Bill notes that his apple tree is 4/5 the size of his pear tree is apple tree is 4 M tall how tall is the pear tree

e-lub [12.9K]1 year ago
7 0

1) Given that the apple tree is 4/5 pear tree we can write

Apple Tree size = 4/5 Peartree

Apple tree= 4m

2) So we can write the following expression for that:

\begin{gathered} Apple=\frac{4}{5}P \\ 4=\frac{4}{5}_{}P \\ 4P=20m \\ P=\frac{20}{4} \\ P=5 \\  \\  \end{gathered}

So the Pear tree is 5 meters tall, and the apple tree is 4/5*5 = 4 m

Solve the system y = -x + 7 and y = -0.5(x - 3)2 + 8<br> I'll mark the brainliest!!!!!!!!!
hram777 [196]

Answer:

(1, 6)

(7, 0)

Step-by-step explanation:

y = -x + 7

y = -0.5(x - 3)² + 8

-x + 7 = -0.5(x - 3)² + 8

-x + 7 = -0.5(x² - 6x + 9) + 8

-x + 7 = -0.5x² + 3x - 4.5 + 8

       0 = -0.5x² + 4x - 3.5

       0 = x² - 8x + 7

       0 = (x - 7)(x - 1)

x - 7 = 0 or x - 1 = 0    

x = 1 or 7

Complete parts ​(a) through ​(c) below. ​(a) Determine the critical​ value(s) for a​ right-tailed test of a population mean at t
olga_2 [115]

Answer:

a) The critical value on this case would be t_{crit}=1.325

b) The critical value on this case would be t_{crit}=-1.345

c) The critical values on this case would be t_{crit}=\pm 2.201

Step-by-step explanation:

Part a

The system of hypothesis on this case would be:

Null hypothesis: \mu \leq \mu_0

Alternative hypothesis: \mu > \mu_0

Where \mu_0 is the value that we want to test.

In order to find the critical value we need to find first the degrees of freedom, on this case that is given df=20. Since its an upper tailed test we need to find a value a such that:

P(t_{20}>a) = 0.1

And we can use excel in order to find this value with this function: "=T.INV(0.9,20)". The 0.9 is because we have 0.9 of the area on the left tail and 0.1 on the right.

The critical value on this case would be t_{crit}=1.325

Part b

The system of hypothesis on this case would be:

Null hypothesis: \mu \geq \mu_0

Alternative hypothesis: \mu < \mu_0

Where \mu_0 is the value that we want to test.

In order to find the critical value we need to find first the degrees of freedom, given by:

df=n-1=15-1=14

Since its an lower tailed test we need to find b value a such that:

P(t_{14}

And we can use excel in order to find this value with this function: "=T.INV(0.1,14)". The 0.1 is because we have 0.1 of the area accumulated on the left of the distribution.

The critical value on this case would be t_{crit}=-1.345

Part c

The system of hypothesis on this case would be:

Null hypothesis: \mu = \mu_0

Alternative hypothesis: \mu \neq \mu_0

Where \mu_0 is the value that we want to test.

In order to find the critical value we need to find first the degrees of freedom, given by:

df=n-1=12-1=11

Since its a two tailed test we need to find c value a such that:

P(t_{11}>c) = 0.025 or P(t_{11}

And we can use excel in order to find this value with this function: "=T.INV(0.025,11)". The 0.025 is because we have 0.025 of the area on each tail.

The critical values on this case would be t_{crit}=\pm 2.201

Choose the correct answers for amount financed and the finance charge in dollars for the following problem. Curtis Hindle purcha
gulaghasi [49]

<u>Answer:</u>

Total paid = $717.3

Finance charge = $167.3

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

The cost price of mountain bike = $550

The down payment on bike = 75% of $550 = 0.75 * 550 = $412.5

We know that he will make 12 payments of $25.40 each so total monthly payments = 12 * 25.40 = $304.8

The total amount paid = Down payment + Total monthly payments = $412.5 + $304.8 = $717.3

The finance charge = Total amount paid - Cost price = $717.3 - $550 = $167.3
