A newsletter publisher believes that 43% of their readers own a Rolls Royce. A testing firm believes this is inaccurate and performs a test to dispute the publisher's claim. After performing a test at the 0.02 level of significance, the testing firm fails to reject the null hypothesis.

Answers

Answer 1

The conclusion regarding the test of the hypothesis is given as follows:

There is not sufficient evidence at the 0.02 level of significance that the percentage is not of 43%.

What are the hypothesis tested?

At the null hypothesis, it is tested if there is not enough evidence to conclude that the percentage is not of 43% = proportion of 0.43, hence:

[tex]H_0: p = 0.43[/tex]

At the alternative hypothesis, it is tested if there is enough evidence to conclude that the percentage is not of 43%, hence:

[tex]H_1: p \neq 0.43[/tex]

The decision was to not reject the null hypothesis, meaning that there is not sufficient evidence at the 0.02 level of significance that the percentage is not of 43%.

Missing Information

The problem asks to identify the correct conclusion from these two options:

There is not sufficient evidence at the 0.02 level of significance that the percentage is not of 43%.There is sufficient evidence at the 0.02 level of significance that the percentage is not of 43%.

An investor obtains a balloon mortgage with the terms shown below.
Balloon Mortgage
$530,000
30/7 balloon
6.8% annual rate
What is the monthly payment on this mortgage?
a. 3,455.20 b. 3,678.58 c. 6,738.57 d. 7,947.40

Answers

9514 1404 393

Answer:

  a.  $3,455.20

Step-by-step explanation:

The monthly payment is given by the amortization formula:

  A = P(r/12)/(1 -(1 +r/12)^(-12t))

for loan amount P at annual rate r for t years.

For this mortgage, we use P = $530,000, r = 0.068, t = 30.

  A = $530,000(0.068/12)/(1 -(1 +0.068/12)^(-360)) ≈ $3,455.20

The monthly payment is $3,455.20.

First. Let’s find the radius. The diameter of the circle is 6in. Radius equals to half of the diameter. That means r=6/2=3in
Now if we find the area of circle, we have to multiply the quadratic of the radius by pi.
A=(3in)^2*3.14=9*3.14=28.26in^2
Now we can find the volume by multiply the area and the height.
V=28.26*8=226.08in^3
Now if we find the cube volume
V=a*b*h=15*9*9=1215in^3
V(toral)=226.08+1215=1441.08in^3

In ADEF, f = 610 inches, e = 590 inches and ZE=70°. Find all possible values of ZF,
to the nearest degree.

Answers

Answer:

"76°" is the appropriate solution.

Step-by-step explanation:

Please find attachment of the diagram according to the given query.

The given values are:

In ΔDEF,

f = 610 inches

e = 590

∠E = 70°

∠F = ?

By using the law of sines, we get

⇒  [tex]\frac{Sin E}{e} =\frac{Sin F}{f}[/tex]

On substituting the values, we get

⇒  [tex]\frac{Sin70^{\circ}}{590} =\frac{SinF}{610}[/tex]

On applying cross multiplication, we get

⇒   [tex]SinF=\frac{610\times Sin 70^{\circ}}{590}[/tex]

On substituting the values, we get

⇒            [tex]=\frac{61\times 0.95969262}{59}[/tex]

⇒            [tex]=\frac{57.3212499}{59}[/tex]

⇒            [tex]=0.971546608[/tex]

now,

⇒  [tex]F=Sin^{-1}(0.971546608)[/tex]

⇒      [tex]=76^{\circ}[/tex]

If gas costs $2.19 per gallon, how many whole gallons of gas could you buy with $17.00? (Make sure to answer with a whole number.)

Answers

With $17.00, you can buy approximately 8 whole gallons of gas.

To calculate the number of whole gallons of gas that can be bought with $17.00, we need to divide the total amount of money by the cost per gallon.

Given that the cost of gas is $2.19 per gallon, we can set up the following equation:

Number of gallons = Total money / Cost per gallon

Substituting the values into the equation, we have:

Number of gallons = $17.00 / $2.19

Performing the division, we get:

Number of gallons ≈ 7.7625570776255707762557077626

Since we are asked to provide a whole number, we round the decimal to the nearest whole number:

Number of gallons ≈ 8

It's important to note that this calculation assumes that the cost per gallon remains constant, and any taxes or additional fees are not taken into account. Additionally, the actual number of gallons that can be purchased may vary depending on the specific pricing and location.
