Answer:
H0; u = 50 average revenue equals 50
H1: u not equal to 50, average revenue not equal to 50
This is 2 tailed
Alpha = 0.05
Z critical = 1.6449
We find the test statistics
Mean = 54.7
Sd = 11
n = 32
barX - u/sd/√n
= 54.70-50/11/√32
= 4.70/1.9435
= 2.418
Decision rule: reject H0 if test statistic > critical value. Accept if otherwise
2.418>1.6449
We reject H0
We conclude that average revenue is not equal to zero
C. P(z>=2.418) = 0.9922
1 - 0.9922
= 0.0078 (I used Ms excel here)
0.0078 < 0.05
So we Reject h0

What is mean by Angle?An angle is a combination of two rays (half-lines) with a common endpoint. The latter is known as the vertex of the angle and the rays as the sides, sometimes as the legs and sometimes the arms of the angle.
We have to given that;
You leaned the ladder against your house at a 30° angle of elevation.
And, The foot of the ladder is 7 feet from the foot of the house.
Now,
Let the length of ladder = x
Hence, We can formulate;
⇒ cos 30° = 7 / x
⇒ √3 / 2 = 7 / x
⇒ x = 14 / √3 feet
Thus, The length of ladder would be,
⇒ 14/√3 feet

3) Let h(x)= |2x|-4. Find h(x) when x = -7.
a) -10
b) 10
c) -13
d) 13
Answer:
[tex]h(x) = 10[/tex]
Step-by-step explanation:
Given
[tex]h(x) = |2x| - 4[/tex]
[tex]x = -7[/tex]
Find h(x)
Substitute -7 for x
[tex]h(x) = |2*-7| - 4[/tex]
[tex]h(x) = |-14| - 4[/tex]
Absolute values return positive. So:
[tex]h(x) = 14 - 4[/tex]
[tex]h(x) = 10[/tex]

Step-by-step explanation:
Shaun is 1.88 m tall.
David is 6 cm taller than Shaun.
How tall is David
David is 1.94 meters tall.
Given that,
Shaun is 1.88 meters tall.
David is stated to be 6 centimeters taller than Shaun.
To determine David's height, we need to add the additional height to Shaun's height.
Since there are 100 centimeters in a meter, we can convert the 6 centimeters to meters by dividing it by 100: 6 cm / 100 = 0.06 meters.
Now, we can add this height to Shaun's height to find David's height:
1.88 meters + 0.06 meters = 1.94 meters.
Therefore, David is 1.94 meters tall.

James has collected 3985 stamps so far. He had 787 stamps from countries other than the United States. What percent of the stamps are from countries other than the United States?
Answer:
divide 787 by 3985 then multiply that by 100
Step-by-step explanation:
if it were 100 stamps total and 50 from non US countries, you could pretty easily tell it was half, or 50% to ge that you need to divide the number in question by the total so 50/100. which gets .5. to get the percent you multiply it by 100
so given the numbers we divide 787 by 3985 then multiply that by 100

What is another way to write the equation 7/8 x 3/4= -6? (Look at picture! Pls hurry)
Answer:
Step-by-step explanation:
Well it doesn't help you very much, but the answer is A. What this does is separates 7/8 x so that (x/8) sits by itself. After you subtract 3/4 from both sides, you can divide both sides by 7. When you do that, you get x/8 = something, but the fractions are going to be awkward at best. I'll just do a very quick run through
7(x/8) = -6 - 3/4
7(x/8) = - 6.75 Divide by 7
x/8 = 0.9642 Multiply by 8
x = 8 * 0.9642
x = 7.7143

If you have $3250 how many board feet can you buy if the cost per board foot is $2.29?
Answer:
If i am right i think its 1419
Step-by-step explanation:
3250/2.29= about 1419
Answer:
1419.21= 1419
Step-by-step explanation:
Divide the amount of money you have with the cost price of what you want to buy.
$3250/$2.29=1419.213974
The answer is a decimal. But we can not have a unit as decimal so we have to round it down to the nearest whole number.
Therefore = 1419
