Answer:
The claim is false.
Step-by-step explanation:
Given the data :
13 24 21 37 15 25 18 22 40 32
The sample mean and standard deviation can ben calculated for the given sample.
Using calculator :
Sample mean, xbar = 24.7
Sample standard deviation, s = 9.04
Sample size, n = 10
The hypothesis :
H0 : μ = 17
H1 : μ ≠ 17
The test statistic :
(xbar - μ) ÷ (s/√(n))
(24.7 - 17) ÷ (9.04/√(10))
7.7 / 2.8586990
Test statistic = 2.694
We can obtain the Pvalue, at α = 0.05 ; df = n-1 = 9
Pvalue = 0.0246
Since Pvalue < α ; we reject the null ; Hence, there is significant evidence to conclude that an adult American does not spend average of 17 hours in leisure
Answer:
(1,2)
Step-by-step explanation:
y = 2x. y = -x+3
Set the two equations equal
2x = -x+3
Add x to each side
2x+x = -x+x+3
3x = 3
Divide by 3
3x/3 = 3/3
x = 1
Now find y
y =2x = 2(1) = 2

Answer:
The answer is 3 inch
Step-by-step explanation:
To start off, the equation you want to use the formula V=whl
Next, you simply plug in the values you already know, so you have 450=w*20*7.5
After you do that you multiply 20 times 7.5 to get which is 150, which leaves you with 450= w *150 to solve for w, you need to isolate it. To do that you divide 450 by 150. You are left with the answer of 3.
Martin's error : The graph of g(x) should be translated 3 units left (not right) from the parent graph.
<u>Concept - Horizontal Translation</u>:
If f(x) is a parent function, then
shifts graph of f(x) by <em>h</em> units to the left.
shifts graph of f(x) by <em>h</em> units to the right.
<u>Given:</u>
Parent function: 
By using concept of horizontal translation,
The graph of g(x) should be translated 3 units left from the parent graph.
i.e. Martin's error : The graph of g(x) should be translated 3 units left (not right) from the parent graph.
