Jim buys a skateboard for $200. The value of the skateboard depreciates by 15% each year
since buying it. Create a function to represent the value of the skateboard, f(2), in dollars,
after 3 years since buying it.

Answers

Answer: f(x)=200•(0.85)^x

Step-by-step explanation:

C(t) is the actual value of the function at time t

Co is the initial value of C at t=0

r is the decaying rate, expressed in decimal

Depreciation is often modeled as an exponential decay function. Since Jim bought a skateboard for Co=$200, its value will depreciate by r=15% = 0.15 each year since buying it.

Which equation represents a line with a slope of -6/5
and a y-intercept of 1?

Answers

Answer:

y = -6/5x + 1

Step-by-step explanation:

The equation that represents a line with a slope of -6/5 and a y-intercept of 1 is y = -6/5x + 1

How to determine the equation?

The given parameters are:

Slope, m = -6/5y-intercept = 1

Let the variable of the equation be x.

A linear equation is represented as:

y = Slope * x + y-intercept

So, we have:

y = -6/5 * x + 1

Evaluate

y = -6/5x + 1

Hence, the equation is y = -6/5x + 1

The ratio of teachers to students at Priory School is 2:27

What is school's total population if there are 42 staff

Answers

Answer:

609

Step-by-step explanation:

ratio of teachers to students at Priory School =2:27

Let X= total number of both the students and the teacher

Ratio of teacher=( 2/29)X

Ratio of student is (27/29 )X

But total number of teacher = 42

2/29 ×X =42

2X= 42×29

2X=1218

X= 609

Hence, school's total population is 609

solve using substitution
-5x+7y=-5
y=-5
x=?

Answers

So if you solve for x using the first equation, you get: x = 5y - 5.

From there you can plug that into the second equation which would give you:

7y-5y+5=-23

Simplifying from that point, you get y = -9.

Now that you have one of the values, you can solve for x by plugging it back into the equation we made (x = 5y - 5) and getting to the answer x = -40.

A) 58.7 <h<64.9
B)59.5<h<61.8
C)59.5<h<64.1
D)61.8<h<64.1

Answers

I am extremely bad at math and I am trying to help other to ask a question, but I personally think C

The interval estimate of the population mean when a random sample is taken of the speed on highway is 59.5<h<64.1. Option C is correct.

What is margin of error?

The probability or the chances of error while choosing or calculating a sample in a survey is called the margin of error.

The interval estimate of the population mean can be found out using the following formula:

[tex]\overline X\pm MOE[/tex]

Here, [tex]\overline X[/tex] is the average mean, and the MOE is the margin of error.

On a highway, a random sample is taken of the speed, in mph, of 50 cars.

A mean speed is 61.8 mphThe margin of error is +2.3 The confidence interval is 95%

Put the values in the above formula as,

[tex]61.8\pm 2.3\\59.5,641[/tex]

Thus, the interval estimate of the population mean

[tex]59.5 < h < 61.8[/tex]

Hence, the interval estimate of the population mean when a random sample is taken of the speed on highway is 59.5<h<64.1. Option C is correct.
