Answer:

Step-by-step explanation:
The slope-intercept form of an equation of a line:

m - slope
b - y-intercept
The point-slope form of an equation of a line:

We have the equation of a line in the slope-intercept form

and the point (-3, 8).
Substitute:

$6500 Step-by-step explanation:
the total is...
2500 added to the commission
the commission is ...
80000 multiplied by the 5 percent
which is 4000
total is 4000 plus the 2500
ans is ...$6500
<u>Estimate
5.</u> 49.2 this is actually 20% but its close enough to estimate <u>
6.</u> 120 this is closer to 150%<u>
7.</u> 226.8 this is 70%
<u>
8.</u> 36 this is closer to 55%
<u>
9.</u> It would be closer to fifteen minutes because 25% = 1/4 and 15/45 = 25% and 45 minutes is close to 50 min
<u>write an equation
</u><u>10.</u> 14% = .14 so .14×64 = 8.96<u>
</u><u>
11.</u> x = .36 × 194 x = 69.84<u>
12.</u> .82x = 73.8 divide each side by .82 x = 90<u>
13.</u> 75 = 50x divide each side by 50 x = 1.50 or 150%
We've got the first number, so now we need the others.
There is 1 possibilty for the first digit, 10 for the middle ones, and 2 for the last one.

Answer: 
Step-by-step explanation:
Given : A company produces a women's bowling ball that is supposed to weigh exactly 14 pounds.
Sample size : n=11
Degree of freedom =n-1=10
Sample standard deviation : s= 0.71 pounds
Significance level for 95% confidence interval :
We assume that the bowling ball weight is normally distributed.
Using chi-square distribution table, the required critical values are :-


Then, the 95% confidence interval for the variance of the bowling ball weight will be :


∴ The 95% confidence interval for the variance of the bowling ball weight will be :
