Answer:

Step-by-step explanation:

We can use long division to solve this.

$33\overline{\smash{)}#2871}$

33 goes into 287 8 times and 33 goes into 231 7 times.

So, 87.

Hope this helped!

Answer:

$\sigma = 121.53$

Step-by-step explanation:

Required

The population standard deviation

First, calculate the population mean

$\mu = \frac{\sum x}{n}$

This gives:

$\mu = \frac{148+ 329+ 491 +167+ 228+285+ 441}{7}$

$\mu = \frac{2089}{7}$

$\mu = 298.43$

The population standard deviation is:

$\sigma = \sqrt{\frac{\sum(x - \bar x)^2}{n}}$

So, we have:

$\sigma = \sqrt{\frac{(148 - 298.43)^2 + ..........+ (441- 298.43)^2}{7}}$

$\sigma = \sqrt{\frac{103387.7143}{7}}$

$\sigma = \sqrt{14769.6734714}$

$\sigma = 121.53$

Olivia is making model cars to go on shelves in her room. The number of wheels she uses is a function of how many cars she makes

Luba_88 [7]

Answer:

Domain = 1 to 7

Range = 4 to 28

Step-by-step explanation:

Given that:

Number of wheels used is a function of number of cars manufactured.

Number of wheels present = 28

1 car uses 4 wheels

2 cars use 8 wheels.

3 car uses 12 wheels

and so on.

Let the function be of the form:

$y =f(x)$

Domain of the function is the value of $x$ that can be given as valid input to the function.

Range of the function is the value of $y$ that can be output of the function.

Let $x$ be the number of cars manufactured.

Then value of $y$ is nothing but $x$ times 4.

$y=4x$

We are given that maximum value of $y$ can be 28.

$28 = 4x\\\Rightarrow x =7$

Therefore, maximum value of input can be 7.

Minimum number of wheels can be 4 to make a minimum of 1 car.

Therefore domain is 4 to 28 and range is 1 to 7.

The future value annuity is given by:
FV=(1+r)*p{[(1+r)^n-1]/r}
our value will be:
FV=(1+0.071/2)*450{[(1+0.071/2)^(9*2)-1]/0.071/2}
FV=11,468.337

The present value of the annuity will be:
FV=PV(1+r)^n
11,468.337=PV(1+0.071)^9
solving for PV we get
PV=6185.791

Answer: PV=$6185.791
