Answers
Answer:
(-3,6)
Step-by-step explanation:
[tex]\frac{1}{3}[/tex] x + [tex]\frac{1}{4}[/tex] y = 1 Divide all the way through by 12 to clear the fraction
4x + 3y = 12 Add this to the second equation
2x -3y = -30
6x = -18 Divide both sides by 6
x = -3
Substitute -3 into either of the original equations to solve for y
4x + 3y = 12
4(-3) + 4y = 12
-12 + 4y = 12 Add 12 to both sides
4y = 24 Divide both sides by 4
y = 6

If the hours of daylight in Miami can be
approximated using a sinusoidal wave, what is the
amplitude of the function if the shortest day in
Miami is 10 hours and 52 minutes long and the
longest day in Miami is 13 hours and 45 minutes
long?
Answers
Answer:
the sinusoidal function that approximates the hours of daylight in Miami has an amplitude of approximately 1.44 hours.
Step-by-step explanation:
The amplitude of a sinusoidal function is half the difference between the maximum and minimum values of the function. In this case, the shortest day in Miami is 10 hours and 52 minutes long, and the longest day is 13 hours and 45 minutes long, so the difference between the maximum and minimum values is 2 hours and 53 minutes, which is equal to 173 minutes. Half of this is 86.5 minutes, which is the amplitude of the function.
To express this in hours, divide the amplitude in minutes by 60. This gives an amplitude of 86.5 / 60 = 1.44 hours.
So, the sinusoidal function that approximates the hours of daylight in Miami has an amplitude of approximately 1.44 hours.

What is partial fraction decomposition?Partially decomposing a rational fraction, also known as partially expanding it, in algebra includes expressing the fraction as the sum of a polynomial and one or more fractions with a lower common denominator.
One technique for breaking down rational expressions into smaller partial fractions is partial fraction decomposition. This method serves the integration process better.
In order to integrate a rational function, it is condensed to a valid rational function. The integrand can be expressed as the sum of more elementary rational functions through the use of partial fraction decomposition.
Therefore, starting with the simplified solution and proceeding backwards, the final expression is “decomposed” into the original polynomial fractions.

Answers
The confidence interval for the given equation will be: 0.504.
What is confidence interval?
In frequency statistics, the confidence interval (CI) is the range of estimated values for an unknown parameter. Confidence intervals are computed at the specified confidence level. A 95% confidence level is the most common, but other levels such as 90% and 99% are sometimes used. The confidence level represents the proportion of corresponding CIs over time that contain the true value of the parameter. For example, 95% of all intervals computed at the 95% level must contain the true value of the parameter.
Factors that affect the width of the CI include sample size, sample variability, and confidence level. All else being equal, a larger sample results in a narrower confidence interval, a more varied sample results in a wider confidence interval, and a higher confidence level results in a wider confidence interval.
Therefore, The confidence interval for the given equation will be: 0.504.

What is meant by triangle?Three edges and three vertices define a triangle as a polygon. One of geometry's fundamental shapes is this one.
Any three points determine a distinct triangle and a distinct plane in Euclidean geometry when they are non-collinear (i.e. a two-dimensional Euclidean space). To put it another way, each triangle is contained in a plane, and there is only one plane that includes that particular triangle. All triangles are contained in one plane if and only if all geometry is the Euclidean plane, however this is no longer true in higher-dimensional Euclidean spaces. Except as otherwise specified, the subject of this article is triangles in Euclidean geometry, more specifically, the Euclidean plane.
Given,
C=61° 50, c=31.2, b=23.6
Sine rule:
sin B/b=Sin C/c
sin B=b sin C/c
=(23.6 sin 61° 50)/31.2
sin B=0.65219
sin B=139.3
A+B+C=180
A=180-B-C
A=180-139.3-61.50
A= -20.8 which is not possible.
Because the angle must be positive.
sin B=sin 40.70
A+B+C=180
A=180-40.70-61.50
A=77.79'
sin A/a=sin C/c
a=c sin A/sin C

A family rents a truck to move from Buffalo to Chicago. The rental has a base cost of $49.95, plus, an additional cost of $1.19 per mile driven. The family also pays for gas, which costs $3.89 per gallon. The truck’s average gas mileage is 18 miles per gallon. The family decided to take a rest in Cleveland, what would be the distance travelled from Buffalo to Cleveland if the total cost of the move is $724.85?
Answers
By solving a linear equation, we will see that the distance is 479.98 miles.
How to find the distance?We know:
The rental has a base cost of $49.95 plus $1.19 per mile.
There is also an extra cost of $3.89 per gallon of gas, and with one gallon they can travel 18 miles, then there is another extra cost of:
$3.89/18 per mile.
Then, if you travel x miles, the total cost is given by the linear equation:
C(x) = $49.95 + ($1.19 + $3.89/18)*x
We want to find the value of x, number of miles, such that the total cost is $724.85, then we need to solve:
$724.85 = $49.95 + ($1.19 + $3.89/18)*x
Let's solve that for x:
$724.85 - $49.95 = ($1.19 + $3.89/18)*x
$674.90 = ($1.19 + $3.89/18)*x
$674.90/($1.19 + $3.89/18) = x
479.98 = x

What do you mean by Factoring of polynomial?
The process of multiplying polynomial factors is known as factoring polynomials. A polynomial of degree "n" in variable x is an equation of the form axn + bxn-1 + kcxn-2 +....+kx+ l, where each variable has a constant acting as its coefficient. A polynomial is an expression that has a constant and a variable together with an addition or a subtraction sign between them.
Factors of polynomials are zeros of polynomials that may be expressed as another linear polynomial. If we divide a given polynomial by any of its components after factorization, the residual will be zero.
Contingents: 1, 2, 5, and 7.variables: x, y, and hTerms: 3x, 8y, and 2h (terms are often separated by a + or a -).(Note that words can also include variables and constants)
Formulas: 3x+1, 4x +5, 2h + 2wEquations: P = 2h + 2w, x = 4, y = x + 2One of the variables or constants that is multiplied by another factor to create a phrase is called a factor. Factors 4 and x make up the phrase 4x. To factor is to divide the object of the multiplication. Therefore, factoring "disassembles" the result of multiplication.
We frequently need to factor a term in order to "solve" (that is, get the value of, say, x) an equation
For Example:
The operation of factoring falls in between multiplication and dividing. Let's examine the following statement:
3x + 12
We can factor out the third because 3x and 9 both share the number three:
3x ÷ 3 = x 12 ÷ 3 = 4
We set it aside what's left after factoring out 3:
3(x + 4)

Answer is 0
Given:- arithmetic sequence 20,18,16,14,....
To find:- 11th term of given arithmetic sequence
Arithmetic Progression (AP) is sequence of numbers in order, in which the difference between any two consecutive numbers is constant value. It is also known as Arithmetic Sequence.
The 11th term of the A.P. can be found by a formula, a(n)=a(1)+(n-1)d , where n is the number of terms, a(1) is teh first term of A.P and d is difference between any two continuously terms.
Number of terms to be found = 11
therefore, a(11) = a(1)+(n-1)d
d=a(2)-a(1)
d=18-20
d=-2
putting value of d in above equation,
a(11) = 20 + (11-1)(-2)
a(11) = 20 - 20
a(11) = 0
hence the 11th term of arithmetic sequence 20,18,16,14,.... is 0.

A cell phone manufacturer guarantees that the mean battery life for its latest cell phone model is at least 36 hours. You are asked to design a hypothesis test to challenge this claim.a. State the null and alternative hypotheses and identify which represents the claim.b. Describe type I and type II errors for a hypothesis test of the claim.c. Explain whether the hypothesis test is left-tailed, right-tailed, or two-tailed.d. Explain how you should interpret a decision that rejects the null hypothesis. e. Explain how you should interpret a decision that fails to reject the null hypothesis.
Answers
Null hypothesis: H₀: population mean, μ ≥ 36hours
Alternate hypothesis: H₁: population mean, μ < 36hours
Given that,
A maker of cell phones promises that the average battery life of its most recent cell phone model is at least 36 hours. To refute this assertion, you are required to create a hypothesis test.
We have to find
a. Describe the null and alternative hypotheses, then choose the one that best supports the claim.
b. Explain type I and type II mistakes for the claim's hypothesis test.
c. Describe if the hypothesis test has left-, right-, or two-tailed distributions.
d. Describe how to read a conclusion that rejects the null hypothesis. a. Describe how you should evaluate a choice that does not rule out the null hypothesis.
We know that,
a. Null hypothesis: H₀: population mean, μ ≥36hours
Alternate hypothesis: H₁: population mean, μ < 36hours
b. Type 1 error: is an error made when we reject the null hypothesis, when the null hypothesis is true. This happens the significance level % of time. In our example, a type 1 error would be made when the population mean is actually greater than 36 hours, but we conclude that the population mean is less than 36 hours.
Type 2 error: is an error made when we fail to reject the null hypothesis, when the null hypothesis is false. This is represented by beta. In our example, a type 2 error would be made when the population mean is actually less than 36 hours, but we conclude that the population mean is not less than 36 hours.
c. The test is left tailed since the area of rejection is on the left side (less than side).
d. We would interpret that at x% confidence level (generally 95%), we reject the claim that the population mean is greater than 36 hours. We would conclude that we have enough evidence from the sample that the population mean is significantly less than 36, and hasn't happened as a matter of chance.

Answer:
68%
Step-by-step explanation:
93 is 7 pts BELOW 100 this represents -7 /15 = -.4666 Z-score
From Z-score table this represents .3192 ..or 31.92 % to the LEFT of the 93 ...... to the RIGHT is 100% - 31.92 % = ~ 68%
A mammogram is used to screen women for breast cancer. False positives are tests that incorrectly show a positive result. 85% of positive mammograms are actually false positives. If 1,000 women receive mammograms, and 200 are told there is an abnormal finding, how many women are likely to actually have breast cancer?
