Step-by-step explanation:

finding the diagonal

= $√((100+576))$

= 26 inches

perimeter of the window = 2(10+24)

= 68 inches

total strands needed to be purchased = [(2×26)+68] inches

= 120 inches of strands

What is 76/100 simplified

Answers

Find the highest common factor between 76 and 100.
Factors of 76: 1, 2, 4, 19, 38, 76
Factors of 100: 1, 2, 4, 5, 10, 20, 50, 100

The highest common factor is 4. Divide 76 and 100 by 4.

$(76)/(100) = (19)/(25)$

A hungry college student just finished eating a large cheese and pepperoni pizza from Doug's Pizza Palace and felt there wasn't enough cheese and pepperoni on it as he has had large pizzas with more cheese and pepperoni on it from this place in the past. This led him to wonder what the average weight of a large cheese and pepperoni pizza was at Doug's Pizza Palace. Doug ordered a large cheese and pepperoni pizza from Doug's Pizza Palace on 15 randomly selected days during a particular term and weighed each before eating it. Suppose all conditions are met for inference using the one-sample t-methods. The student constructed a 95% confidence interval for the population mean using the one-sample t-methods. How many degrees of freedom does the t critical value have?

Answers

Answer: 14

Step-by-step explanation:

Degrees of freedom is the number of values in the evaluation of a test statistic that are free to vary.

For t-statistic , the degree of freedom for a sample with sample size 'n' is given by :-

$df=n-1$

Given : Sample size : n-1

Then, the number of degrees of freedom the t-value will have :-

$df=15-1=14$

Hence, the t-value will have 14 degrees of freedom.
