Answer:

The answer is (x - 9)(x - 2), or x2 - 11 + 18.

Step-by-step explanation:

Well, think about it. What two numbers add to -11 and multiply to get 18? -9 and -2 add to get -11 and multiply to get 18.

Jim wants to purchase a used car. The price is $12,000 cash or $2,500 down and 24 monthly payments of $450.00. Jim decided to fi

ASHA 777 [7]

<h2>Answer</h2>

The amount that will be financed: $9500

The total amount of the monthly payments: $10,800

The amount of the finance charge: $1,300

<h2>Explanation</h2>

Remember that the down payment is the initial amount you paid to reduce the amount you finance.

Given that, the amount that Jim will finance will be the price of the bath in cash minus the down payment:

Amount that will be financed = $12,000 - $2,500 = $9500

Next, to find the total amount of the monthly payments, we just need to multiply the monthly payment by the total number of monthly payments:

Total amount of the monthly payments = $450.00*24 = $10,800

Finally, to find the financial amount, we just need to subtract the financed amount from the total amount of the monthly payments:

Amount of the finance charge = $10,800 - $9500 = $1,300

Work out the perimeter of this semicircle. take pi to be 3.142

Vanyuwa [196]

Answer:

P = 25.71 cm

Step-by-step explanation:

Perimeter of semicircle = πD/2

Where D=10 cm

P = (3.142)(10)/2

P = (3.142)(5)

P = 15.71 cm

Complete Perimeter of Semicircle = P + Diameter

= 15.71 + 10

= 25.71 cm

Basic Computation: Testing M1 2 M2 A random sample of 49 measurements from a population with population standard deviation 3 had

Elenna [48]

Answer:

The sample statistics follows a standard normal distribution since the sample size are large enough.

Step-by-step explanation:

Given that:

First population:

Sample size $n_1$ = 49

Population standard deviation $\sigma_1$ = 3

Sample mean $\overline x _1$ = 10

Second population:

Sample size $n_2$ = 64

Population standard deviation $\sigma_2$ = 4

Sample mean $\overline x_2$ = 12

The sample statistics follows a standard normal distribution since the sample size are large enough.

The null and alternative hypotheses can be computed as:

$\mathbf{H_o:\mu_1=\mu_2}$

$\mathbf{H_1:\mu_1\ne\mu_2}$

Level of significance = 0.01

Using the Z-test statistics;

$Z = \dfrac{\overline x_1 - \overline x_2}{\sqrt{\dfrac{\sigma_1^2}{n_1} + \dfrac{\sigma_2^2}{n_2}}}$

$Z = \dfrac{10- 12}{\sqrt{\dfrac{3^2}{49} + \dfrac{4^2}{64}}}$

$Z = \dfrac{-2}{\sqrt{\dfrac{9}{49} + \dfrac{16}{64}}}$

$Z = \dfrac{-2}{\sqrt{0.18367 +0.25}}$

$Z = \dfrac{-2}{\sqrt{0.43367}}$

$Z = \dfrac{-2}{0.658536}$

Z = - 3.037

Z $\simeq$ - 3.04

The P-value = 2P (z < -3.04)

From the z tables

= 2 × (0.00118)

= 0.00236

Thus, since P-value is less than the level of significance, we fail to reject the null hypotheses $H_o$
