Answer:

To earn $65 in interest in 16 months at a simple interest rate of 3%, you would need to invest $2,166.67. The formula for calculating simple interest is I = P * R * T, where I is the interest earned, P is the principal amount invested, R is the interest rate, and T is the time in years. In this case, we are given that the interest rate is 3%, the time is 16 months, and the interest earned is $65, so we can plug these values into the formula to solve for the principal amount invested:I = P * R * T

$65 = P * 0.03 * (16/12)

$65 = P * 0.03 * (4/3)

$65 = P * 0.01

P = $2,166.67Therefore, to earn $65 in interest in 16 months at a simple interest rate of 3%, you would need to invest $2,166.67.

Answer:

[tex]y=-1/4x+3[/tex]

Step-by-step explanation:

Slope-intercept form is of the form y=mx+b where m is the slope and b is they y-intercept. To solve for the slope, we take the difference of two y-coordinates divided by the x-coordinates difference. Doing this, we get

[tex](3-1)/(0-4)[/tex]

[tex]=-1/4[/tex]

This is our slope. The y-intercept is 3, because the line hits the y-axis when y=3.

Thus, our equation is y=-1/4x + 3.

What is an exponential function?

The definition of an exponential function is given by the equation

y = aeᵇˣ, where a and b are constants.

The given function is f(x) = 87000(0.9)ˣ.

Given that x = 0 represents the year 2010.

Therefore, x= 5 represents the year 2015.

Substitute x = 5 into the given function:

f(5) = 87000(0.9)⁵

    ≈ 51373

Hence, the population of Orange country is about 51373 in 2015.

Now, the population of Greene country was 78000 in 2010 and has decreased exponentially at a rate of 8% each year.

The population of Greene city after 5 years is given by:

78000(1-8%)⁵

= 78000(1 - 0.08)⁵

= 78000(0.92)⁵

= 51408

Therefore, the population of Greene country in 2015 was 51408 which is greater than the population of Orange country in 2015.

Scatter plots exists essential because they can demonstrate the degree of correlation, if any, between the values of observed quantities or occurrences.

Several dots are placed on a horizontal and vertical axis to form a scatter plot. In statistics, scatter plots are crucial because they can demonstrate the degree of correlation, if any, between the values of observed quantities or occurrences (called variables).

Using data visualization, a scatter plot may be used to show how several variables relate to one another. Put different data points between an x- and y-axis to display this data. The name of this form of data visualization comes from the way that each of these data points appears to be "scattered" over the graph.

The graphs known as scatter plots show the relationship between two variables in a data set. On a two-dimensional plane or in a Cartesian system, it represents data points. The dependent variable is represented on the Y-axis, and the independent variable or attribute is plotted on the X-axis.

You can afford the amount of $24588.44 expensive a car.

A monthly payment is a payment made every month to pay off loans or advances. It's similar to EMI.

The monthly payment = Total payback / No. of payment

$325 = Total payback / 108

Total payback = $325 x 108 = $351,00

Let the affordable amount of the car would be P

The total payback = P× r/100 × T + P

Here P, r = 4.75, and T = 9 years

$351,00 = P × (4.75/100 × 9 + 1)

$351,00 = P × ( 0.4275 + 1)

$351,00 = P × 1.4275

P = 351,00 / 1.4275

Apply the division operation, and we get

P = $24588.44

Therefore, you can afford the amount of $24588.44 expensive a car.

Explanation:

The inequality represents the greater than ">" or lesser than "<".

∵ The temperature is less than 3 the answer is x < 3.

#SPJ4

The following inequality represents temperatures below 3°F

c. x < 3

A relationship between two expressions or values that is not equal to each other is referred to as "inequality" in mathematics. So inequality results from an imbalance. For instance, let's say you want to spend $250 on a new bicycle but only have $225. The fact that you are comparing two non-equal numbers makes it an inequality as well.

When two quantities are equal, the symbol "=" is used, and when they are not equal, the symbol "" is used to denote that. When two values are not equal, the first value may be greater than (>), less than (<), greater than equal to (≥), less than equal to (≤). In light of the example given above, 250 > 225.

Solution:

The less than symbol represented as < is only available in x < 3, it is also available in  x < -3 but we have given that temperature ins 3°F and not -3°F.

Thus the correct answer is c. x < 3

Answer:

a²b²

Step-by-step explanation:

Variables cancel out when they are divided by itself because they represent the same thing.

a³ / a = a²

b^4/b² = b²

Thus, the final answer is a²b².

(a) The probability of each possible number of sets that are acceptable without any adjustment can be found using the binomial distribution formula:

P(x) = (n choose x) * p^x * (1-p)^(n-x)

Where:

P(x) is the probability of x successes in n trials

n is the number of trials (in this case, the number of sets produced in a week)

x is the number of successes (in this case, the number of sets that are acceptable without any adjustment)

p is the probability of success (in this case, the probability that a set is acceptable without any adjustment, which is 0.70)

Plugging in the values, we get:

P(0) = (3 choose 0) * 0.70^0 * (1-0.70)^(3-0) = 0.028

P(1) = (3 choose 1) * 0.70^1 * (1-0.70)^(3-1) = 0.081

P(2) = (3 choose 2) * 0.70^2 * (1-0.70)^(3-2) = 0.162

P(3) = (3 choose 3) * 0.70^3 * (1-0.70)^(3-3) = 0.126

(b) To find the expected number of sets that are tested and found to be acceptable without adjustment, we can use the formula:

E(x) = n * p

Plugging in the values, we get:

E(x) = 3 * 0.70 = 2.1

The expected number of sets that are tested and found to be acceptable without adjustment is 2.1.

(c) The cumulative probability distribution for the number of sets that are tested and found to be acceptable without adjustment is the sum of the probabilities of each possible number of successes. For example, the probability of 0 or 1 successes is the sum of the probabilities of 0 and 1 successes: P(0 or 1) = P(0) + P(1) = 0.028 + 0.081 = 0.109. The probability of 0, 1, or 2 successes is the sum of the probabilities of 0, 1, and 2 successes: P(0 or 1 or 2) = P(0) + P(1) + P(2) = 0.028 + 0.081 + 0.162 = 0.271.

The cumulative probability distribution for the number of sets that are tested and found to be acceptable without adjustment is:

P(0) = 0.028

P(0 or 1) = P(0) + P(1) = 0.028 + 0.081 = 0.109

P(0 or 1 or 2) = P(0) + P(1) + P(2) = 0.028 + 0.081 + 0.162 = 0.271

P(0 or 1 or 2 or 3) = P(0) + P(1) + P(2) + P(3) = 0.028 + 0.081 + 0.162 + 0.126 = 0.397

The corresponding graph would be a step function with a step at each possible value of x (in this case, 0, 1, 2, and 3) and the corresponding probability at each step.

Answer: The rates are not equivalent.

Step-by-step explanation: You have to find the unit rate. This means the number of laps per minute. To find this out you have to divide 12 by 4 which equals 3 and divide 18 by 8 which equals 2.25. Now we know the rates are not equivalent because your rate is 3 laps/minute and your friend's rate is 2.25 laps/minute.

Answer: The rates are not equivalent

Step-by-step explanation:

Firstly,You must identitify the ratio.
The ratio can be 12:4 and 18:8.

Now we must convert 4 minutes and minutes into seconds to make it easier for us to work with.
4 * 60 = 240

18 * 60 = 1080

Now the question is 12: 240 equavialent to 18: 1080.

Method A:

For 12:240 to get 1 lap :

we can divided 240/12 = 20.

1 lap takes 1/3 of a minute or 20seconds.

For 18:1080:

We divide 1080/18 = 60= 1 minute

12:240=20 seconds

18:1080= 60 seconds.

They are not equivalent.

Method B:Compare 12:240 to 18:1080 and divide by 2

if the ratio  split 50/50,they are equavalent.

Add the seconds together,becuase that is the total time

1080+240= 1320 second.

12+ 18=20

Now the ratio is 30:1320

1 lap takes 1320 / 30 = 44seconds

12 laps * 44 = 528s

18laps * 44 = 792s

528s is not 792s.

The statement that is true about the proportional relationship:

Where c is the total cost and p is the number of pounds of shrimp bought at a grocery store.

This means that if you buy one pound  (p = 1) the total cost will be:

C = 13.99*1

C = 13.99

By conducting mathematical operations, we know that John's gross pay will be $1,012 if he works 44 hours a week.

A mathematical "operation" is the process of calculating a value utilizing operands and a math operator.

The supplied operands or integers must adhere to a set of predefined rules that are connected to the symbol of the math operator.

The order of operations refers to the rules that specify how to solve an expression including many operations.

Parentheses, Exponents, Multiplication, Division, Addition, and Subtraction are all referred to as PEMDAS (from left to right).

So, we know that:

John earns $22 per hour for the first 40 hours of a week.

After every additional hour, he earns 1.5 times $22 each hour.

22 * 1.5 = $33

So, John's gross pay if he worked 44 hours will be:

22*40 + 33*4

Since the first equation of system B is created by multiplying system A's second equation by four, both equations will have the same answer. option c is correct

Equations are mathematical expressions that have two algebraic expressions on either side of an equals (=) sign. . For an unknown quantity represented by an unknown variable, equations can be solved to determine its value. A statement is not an equation if it contains no references to "equal to" symbols.

Here,

you have a two-equation system.

System A: 6x + y = 2, and -x - y = 3.

System B: -10 = 2x - 3y, -3 = x - y

Choose the statement about each of the two systems of equations that is true from the list provided.

System A is an example.

6x + y = 2 ......(1) (1)

-x -y = -3 ....(2) (2)

Equation (2) becomes when we double it by 4.

-4x -4y = -12 ......(3) (3)

We now have, after adding (1) and (3),

6x + y +(-4x - 4y) = 2 - 12

solving, we arrive at,

6x + y -4x - 4y = 2 - 12

Equation (1) of system B is 2x – 3y = – 10.

The answer to system A is now discovered.

Equation (2) is created by adding equation (1).

6x + y - x -y = 2 -3

5x = -1

Value of x in (2) yields,

The answer to system B is now discovered.

System B: 2x - 3y = -10... (4)

-x -y = -3 .....(5) (5)

By dividing equation (5) by 3, we get y=16/5

-3x -3y = -9 .......(6) (6)

Equation (6) is obtained by deducting equation (4).

2x - 3y-(-3x - 3y) = -10 +9

5x = -1

Using (5) as the value of x, we obtain x=-1/5

Therefore, the values of systems A and B are equal.
