Answer:

Step-by-step explanation:
<u>Inequalities</u>
To solve the inequality:

We need to perform the required operations on both sides of the inequality to have the variable w isolated.
First, we subtract 9:


Subtracting 6w:

Operating:
-7w>-1
Now we divide by -7 but recall that when dividing by a negative number, we must flip the inequality sign:

Operating:

Answer:
The <em>p</em>-value is 0.809.
Step-by-step explanation:
In this case we need to perform a significance test for the standard deviation.
The hypothesis is defined as follows:
<em>H</em>₀: <em>σ</em>₀ = 4 vs. <em>Hₐ</em>: <em>σ</em>₀ ≤ 4
The information provided is:
<em>n</em> = 9
<em>s</em> = 3
Compute the Chi-square test statistic as follows:


The test statistic value is 4.5.
The degrees of freedom is:
df = n - 1
= 9 - 1
= 8
Compute the <em>p</em>-value as follows:

*Use a Chi-square table.
Thus, the <em>p</em>-value is 0.809.
Answer:
The person bikes 20 miles in an hour
Step-by-step explanation:
Let the number of $1 bill be x and $5 bill be y
x=5y
5y+y=48
6y=48
x=40
y=8
number of $1 bill= 40
number of $5 bill = 8
