The accounting at GEICO notices that the average claim might be larger than $1800, which was previously set as a true average cl

aim amount.
If the actual average is higher, the company will be loosing money in the long run. They ran domly select 45 claims, and calculate a sample mean of S1,920.

Suppose that the variance of claims is known to be equal to S1600.

(a) Set the significance level to α 0.05 and use the hypothesis testing to check if the average claim is larger than $1800.

(b) Find the probability of Type I error.

(c) Find the p-value corresponding to the given sample.

Calculate the unpaid balance, finance charge, and new balance using the unpaid balance method. Note: interest rate is given as a

Karolina [17]

Answer:

The new balance will be $385.04.

Step-by-step explanation:

Previous balance = $179.32

Payments/credits = $85.00

Unpaid balance = $179.32+85$ = $264.32

Monthly rate = 1.25%

Finance charge = $0.0125\times264.32$ = $3.30

New purchases = $117.42

New balance = $264.32+3.30+117.42$ = $385.04

Consider the function FX equals -2/3 X -24 which conclusions can be drawn about F negative 1X select two options a F negative 1X

omeli [17]

The conclusions that can be drawn about f–1(x) are:

$f^-^1(x)$ has an x-intercept of (-36, 0)
$f^-^1(x)$ has a range of all real numbers.

<h3>Calculations and Parameters:</h3>

Given:

$f(x) = \frac{-2}{3}x - 24$

$f(x) + 24 = \frac{-2}{3}x$

To find x, we would multiply both sides by -2/3

= $x= \frac{-3}{2} (f(x) + 24)$

$f^-^1(x) = -\frac{3}{2} (0) - 36$

$f^-^1(x) = -36$

Therefore, $f^-^1(x)$ has an x-intercept of (-36, 0)

Furthermore, $f^-^1(x)$ has a range of all real numbers.

Write the equation of the line that passes through points (-4, 5) and (0,13) in slope-intercept form.

LiRa [457]

Answer:

The answer is

$y = 2x + 13$

Step-by-step explanation:

Remember:

$Slope-intercept form: \: \\ y = mx + b \\ \\ m = slope \\ b = y - intercept$

$M = \frac{y_2 - y_1}{x_2 - x_1}$

First: Find the slope.

$M = \frac{13 - 5}{0 - ( - 4)} = \frac{8}{4} = 2$

.

Second: Solve for the y-intercept

$y = mx + b \\ 5 = 2( - 4) + b \\ 5 = - 8 + b \\ \frac{+ 8 = + 8 \: \: \: \: \: \: \: \: }{13 = b}$

.

Third: Plug in.

$y = mx + b \\ y = 2x + 13$

Which expression is equivalent to -32 to 3/5 power

levacccp [35]

<u>Answer:</u>

8

<u>Step-by-step explanation:</u>

We are given the following expression and we are to find the simplest form of this expression:

$- 3 2 ^ { \frac { 3 } { 5 } }$

First of all, we will factor the coefficient:

$3 2 = 2 ^ 5$

Rewriting it as:

$- ( 2 ^ 5 ) ^ { \frac { 3 } { 5 } }$

Applying the exponent rule $(a^b)^c = a^{bc}$ to get:

$-2^{5.\frac{3}{5}}=-2^3$

$-2^3=-8$
