Answer:

19,180, and 181 are side lengths of a right triangle.

Step-by-step explanation:

All of them do not fit the formula a squared + b squared= c squared except for 19+180+181 because:

19 squared= 361

180 squared= 32400

32400+361= 32761

the sq. root of 32761=181

Yuliya22 [10]

Answer: There are 980 degrees of freedom for the within subjects factor.

Step-by-step explanation:

Since we have given that

Number of groups = 20

Number of participants in each group = 50

So, number of participants in 20 groups is given by

$20\times 50\\\\=1000$

As we know that

Degrees of freedom for the within subjects factor would be

$v=n-k\\\\v=1000-20\\\\v=980$

Hence, there are 980 degrees of freedom for the within subjects factor.

Mr. Autry bought a hat for $99.90. He also bought a pair of boots for $89.90. What was the total cost of the hat and boots inclu

Pepsi [2]

Answer:

$204.98

Step-by-step explanation:

Step 1: Add both item cost

$99.90 + 89.90 = 189.80$

Step 2: Find the sales tax of the result

$\frac{8}{100}\times 189.8 = 15.184$

Step 1: Convert 8% to fraction
$8\%= \frac{8}{100}$
Simplify
$\frac{8}{100} = \frac{2}{25}$
Step 2: Convert 189.80 to a fraction
$189.80 = \frac{189.8}{1}$
Step 3: Set it up
$\frac{2}{25}\times \frac{189.8}{1}$
Step 4: Cross divide
$189.80 \div 25 = 7.592\\2 \div 1 = 2$
Step 5: Multiply the result
$7.592 \times 2 = 15.184$

Step 3: Add the result from the total cost of both items

$189.80 + 15.184 = 204.98$

The total cost of the hats and boots including sales tax is 204.98 dollars
