Answer:

The Scale Factor is 1/4.

Step-by-step explanation:

if you multiply each side (of figure A) by 1/4, the product matches with figure B's corresponding sides. for example, 56 to 14, 28 to 7, and 64 to 16.

the scale factor is just how much a chosen shape is multiplied by to get the next shape.

to get bigger shapes into a smaller shape, multiply the sides by fractions like we did this problem.

True. A biweekly compounding will generate a higher annual percentage yield (APY) than a monthly compounding.

True. A biweekly compounding frequency will generate a higher annual percentage yield (APY) compared to a monthly compounding frequency. The APY takes into account the effect of compounding on the total return of an investment over a year.

Biweekly compounding means that interest is calculated and added to the account balance every two weeks, resulting in more frequent compounding periods throughout the year. This more frequent compounding leads to the accumulation of interest on a larger balance, thus generating a higher APY.

On the other hand, monthly compounding occurs once a month, resulting in fewer compounding periods and a lower overall APY. Therefore, for the same nominal interest rate, a biweekly compounding schedule will yield a higher APY compared to a monthly compounding schedule.

Answer:

a. 19 Questions

b. No, Collins grade was 81%, or B-minus :(

Step-by-step explanation:

There are 21 questions in total on the test. Collin wants a 90 percent at least. If you multiply 21 by 90 percent (as below), you will get 18.9

[tex]21 * .9\\=18.9[/tex]

Of course, you can't get 18.9 questions right (unless you're teacher gives .9 extra points lol, So we need to round UP to a whole number (don't round down because it'll give you a number lower than what 90 percent would equate to.

And, Collin got 17 questions right. That's equivalent to 81 percent of 21 (as below).

[tex]17 / 21\\=.8095[/tex]

This rounds to about 81%, meaning Collin did not reach his goal :(. Oh well, he'll just have to try harder next time!

The general solution to the initial value problem is:

y(t) = y_c(t) + y_p(t)

= 8 cos(√7t) + cos(√7t)

To solve the initial value problem using the method of undetermined coefficients, we assume a particular solution of the form:

y_p(t) = A sin(√7t) + B cos(√7t)

where A and B are constants to be determined.

Taking the first and second derivatives of y_p(t), we have:

y'_p(t) = A√7 cos(√7t) - B√7 sin(√7t)

y''_p(t) = -A(√7)^2 sin(√7t) - B(√7)^2 cos(√7t)

Substituting these derivatives back into the differential equation, we get:

(-A(√7)^2 sin(√7t) - B(√7)^2 cos(√7t)) + 7(A sin(√7t) + B cos(√7t)) = 7 sin(√7t)

Simplifying, we have:

(-A(√7)^2 + 7A) sin(√7t) + (-B(√7)^2 + 7B) cos(√7t) = 7 sin(√7t)

To satisfy this equation for all t, the coefficients of sin(√7t) and cos(√7t) must be equal to the corresponding coefficients on the right side.

Therefore, we have the following system of equations:

-A(√7)^2 + 7A = 0 (coefficient of sin(√7t))

-B(√7)^2 + 7B = 7 (coefficient of cos(√7t))

Solving these equations, we find:

A = 0

B = 1

So, the particular solution is:

y_p(t) = cos(√7t)

To find the general solution, we need to find the complementary solution by solving the homogeneous equation:

y'' + 7y = 0

The characteristic equation is:

r^2 + 7 = 0

Solving this quadratic equation, we find two complex roots:

r₁ = √7i

r₂ = -√7i

The complementary solution is then:

y_c(t) = C₁ cos(√7t) + C₂ sin(√7t)

where C₁ and C₂ are constants to be determined.

Using the initial conditions y(0) = 8 and y'(0) = √7, we can substitute these values into the general solution and solve for C₁ and C₂.

y(0) = C₁ cos(0) + C₂ sin(0) = C₁ = 8

y'(0) = -C₁√7 sin(0) + C₂√7 cos(0) = C₂√7 = √7

Therefore, C₁ = 8 and C₂ = 1.

The general solution to the initial value problem is:

y(t) = y_c(t) + y_p(t)

= 8 cos(√7t) + cos(√7t)

Answer:

No. of students enrolled in Health = 63

No. of students enrolled in P.E. = 181

Step-by-step explanation:

Given,

Total students in grade seven = 244 students

A.T.Q.

Let the number of students enrolled in Health be x

so, The number of students enrolled in P.E. = 3x - 8

As we know,

x + (3x - 8) = 244

4x = 244 + 8

x = 252/4

x = 63

Thus, the number of students enrolled in Health = 63

The number of students enrolled in P.E. = 3x - 8

= 3 * 63 - 8

= 189 - 8

= 181 students

Answer:  C

Step-by-step explanation:

6∫[2,6] (1 + (f'(x))²) dx + 16∫[2,6] x dx = 6S²V1 + 16x dx. To solve this equation, we need additional information about the curve, such as a boundary condition or another equation that relates f(x) and f'(x).

To find a curve that passes through the point (1, 5) and has an arc length on the interval [2, 6] defined by the expression 6S²V1 + 16x dx, we can follow these steps:

Step 1: Determine the general form of the curve equation.

Step 2: Use the arc length formula to obtain an equation involving the curve's equation.

Step 3: Solve the resulting equation to find the specific curve.

Let's proceed with each step:

Step 1: Determine the general form of the curve equation.

Let's assume the curve equation is y = f(x), where f(x) represents the unknown function describing the curve.

Step 2: Use the arc length formula to obtain an equation involving the curve's equation.

The arc length formula for a curve defined by y = f(x) is given by:

S = ∫[a,b] √(1 + (f'(x))²) dx

We are given that the arc length on the interval [2, 6] is defined by the expression 6S²V1 + 16x dx. Substituting the formula for arc length, we have:

6∫[2,6] (√(1 + (f'(x))²))²dx + 16∫[2,6] x dx

Simplifying, we get:

6∫[2,6] (1 + (f'(x))²) dx + 16∫[2,6] x dx

Step 3: Solve the resulting equation to find the specific curve.

Since the expression 6S²V1 + 16x dx represents the arc length on the interval [2, 6], we need to equate it to the arc length formula obtained in Step 2.

6∫[2,6] (1 + (f'(x))²) dx + 16∫[2,6] x dx = 6S²V1 + 16x dx

To solve this equation, we need additional information about the curve, such as a boundary condition or another equation that relates f(x) and f'(x). Without such information, it is not possible to determine the specific curve. Please provide additional constraints or information if available to proceed further in finding the specific curve.

The two unknown integers can be found by graphing the given equations. The larger integer is 10, and the smaller integer is 8.

Let's represent the larger integer as 'x' and the smaller integer as 'y.' According to the given information, we have two equations:

Equation 1: 2x + 3y = 46

Equation 2: x^2 + 4x = 20y + 5

To solve this system of equations, we can graph both equations on the same coordinate plane. The point where the two graphs intersect will give us the values of 'x' and 'y' that satisfy both equations simultaneously.

For equation 1, we rearrange it to y = (46 - 2x)/3. Plotting this equation on the graph, we see a straight line.

For equation 2, we rearrange it to x^2 + 4x - 20y - 5 = 0. Plotting this equation, we get a quadratic curve.

By examining the graph, we can see that the two lines intersect at a point where 'x' is approximately 10 and 'y' is approximately 8. Therefore, the larger integer is 10, and the smaller integer is 8.

By substituting these values back into the original equations, we can verify that they satisfy both equations.

Since s = Σ(xi - x) / n is the sample variance therefore,

Option (a) x/r is correct.

To find the maximum likelihood estimate of β,

We need to maximize the likelihood function L(β) with respect to β.

The likelihood function for a negative binomial distribution with parameters β and r, given n observations with mean x, is,

⇒ L(β) = (Γ(r+n)/Γ(r)n!)  (β^r / (β+x)^r+n) ∏([tex]x_i[/tex]+x)/(([tex]x_i[/tex]+β)^r+1

where Γ is the function and ∏ denotes the product over all n observations xi.

Taking the natural logarithm of the likelihood function, we get,

⇒ ln L(β) = ln(Γ(r+n)) - ln(Γ(r)) - ln(n!) + r ln(β) - (r+n) ln(β+x) + Σ ln(xi+x) - Σ ln(xi+β) - (r+1)Σ ln(xi+x)

To find the maximum likelihood estimate of β,

we take the derivative of ln L(β) with respect to β,

set it equal to zero, and solve for β,

⇒ d/dβ ln L(β) = r/β - (r+n)/(β+x) + Σ 1/(xi+β) - (r+1)Σ 1/(xi+x) = 0

We can solve this equation numerically using iterative  methods, but we can also simplify it by using the fact that when the derivative of a function equals zero, the function is at a maximum or minimum.

Multiplying both sides of the equation by β(β+x), we get.

⇒ r(β+x) - (r+n)β + β(β+x)Σ 1/(xi+β) - (β+x)(r+1)Σ 1/(xi+x) = 0

Simplifying and solving for β, we get,

⇒ β = x(r+n-1) / (Σ 1/(xi+β) - (r+1)Σ 1/(xi+x))

We can use an iterative method to solve for β, starting with an initial estimate of β and updating it until convergence.

One common method is to use the Newton-Raphson algorithm.

After some algebraic manipulations,

we can show that the maximum likelihood estimate of β is,

⇒ B =  x(r / s - 1)

Here s = Σ( - x) / n is the sample variance of the n observations. Therefore, the correct option is (a) x/r.

The correct option id D. There is a 9.52% chance that a random sample of 100 Cal State East Bay students would have more than our sample's 36 working full-time

A study was conducted to determine if more than 30% of Cal State East Bay students work full-time.

The sample of Cal State East Bay students selected was random.

Out of 100 students, 36 were found to be working full-time.

The p-value was calculated to be 0.0952.

The probability of having more than 36 Cal State East Bay students working full-time out of a random sample of 100 students is 9.52% if exactly 30% of Cal State East Bay students work full-time.

Therefore, it is concluded that the null hypothesis cannot be rejected.

The p-value is greater than 0.05 which shows the significance level.

Hence, we accept the null hypothesis.

The null hypothesis states that the proportion of Cal State East Bay students who work full-time is not greater than 30%.

The alternate hypothesis states that the proportion of Cal State East Bay students who work full-time is greater than 30%.

The test is a right-tailed test.

The sample proportion is p = 0.36. The test statistic is given as Z = (p - P0) / √ [P0 (1 - P0) / n]Z = (0.36 - 0.30) / √ [(0.30) (0.70) / 100] = 1.76The p-value is given as 0.0392.

Since the p-value is less than 0.05, we can reject the null hypothesis.

Thus, we can conclude that more than 30% of Cal State East Bay students work full-time.

Hence, option D is the correct answer.

There is a 9.52% chance that a random sample of 100 Cal State East Bay students would have more than 30% working full-time.

a) The mean and standard deviation need to be determined for the given data on the number of ways each sum can be obtained when rolling three dice.

b) A frequency polygon can be drawn to represent the data.

c) Whether the data has a normal distribution or not needs to be determined, and an explanation is required.

a) Mean and Standard Deviation: The mean can be calculated by summing up the products of each value and its corresponding frequency, then dividing by the total frequency. The standard deviation can be calculated by finding the square root of the variance, where the variance is the sum of the squared differences between each value and the mean, divided by the total frequency.

b) Frequency Polygon: A frequency polygon can be plotted by taking the sum values on the x-axis and the corresponding frequencies on the y-axis. Points are plotted for each sum value, and then lines are drawn to connect these points to form the polygon.

c) Normal Distribution: To determine if the data follows a normal distribution, one can visually analyze the frequency polygon. If the polygon displays a symmetric, bell-shaped curve, it suggests a normal distribution. However, if the polygon is skewed or does not exhibit a bell shape, the data is unlikely to have a normal distribution.
