Answer:

The answer is 4th point.

Step-by-step explanation:

You can do it by seperating everything out and put everything back in the end :

(-5/6)×(√72)×(√p)

= (-5/6)×(√2×36)×(√p)

= -5/6 × 6√2 × √p

= -5√2 × √p

= -5√2p

<em>Six (6)</em> different pizzas can be made with one vegetable and one meat.

They are:

1). broccoli, pepperoni

2). broccoli, sausage

3). peppers, pepperoni

4). peppers, sausage

5). onions, pepperoni

6). onions, sausage

Estimate = 700 lbs

Real bear = 634 lbs

Difference = (700 - 634) = 66 lbs

The estimate is <em>66 pounds more</em> than the actual weight.

The estimate is 10.4% too high.

The actual bear weighs 9.4% less than the estimate.

Vina has $4.70 in quarters, dimes and nickels in her purse. She has eight more dimes than quarters and six more nickels than qua

DanielleElmas [232]

Nickels (0.05): Q + 6

Dimes (0.10): Q + 8

Quarters (0.25): Q

Nickels + Dimes + Quarters = Total

0.05(Q + 6) + 0.10(Q + 8) + 0.25(Q) = 4.70

0.05Q + 0.30 + 0.10Q + 0.80 + 0.25Q = 4.70

0.40Q + 1.10 = 4.70

0.40Q = 3.60

Q = 9

Nickels (0.05): Q + 6 = (9) + 6 = 15

Dimes (0.10): Q + 8 = (9) + 8 = 17

Answer: Nickels = 15, Dimes = 17, Quarters = 9

Below are the jersey numbers of 11 players randomly selected from a football team. Find the range, variance, and standard deviat

Aleksandr-060686 [28]

Answer:

Range = 71

Variance = 546.0

Standard Deviation = 23.4

Option A) Jersey numbers are nominal data that are just replacements for names, so the resulting statistics are meaningless.

Step-by-step explanation:

We are given the following data set in the question:

33, 29, 97, 56, 26, 78, 83, 74, 65, 47, 58

Formula:

$\text{Standard Deviation} = \sqrt{\displaystyle\frac{\sum (x_i -\bar{x})^2}{n-1}}$

$\text{Variance} = \displaystyle\frac{\sum (x_i -\bar{x})^2}{n-1}$

where $x_i$ are data points, $\bar{x}$ is the mean and n is the number of observations.

$Mean = \displaystyle\frac{\text{Sum of all observations}}{\text{Total number of observation}}$

$Mean =\displaystyle\frac{646}{11} = 58.7$

Sum of squares of differences = 5460.18

$\text{Variance} = \frac{5460.18}{11} = 546.0$

$S.D = \sqrt{\frac{5460.18}{10}} = 23.4$

Sorted Data Set: 26, 29, 33, 47, 56, 58, 65, 74, 78, 83, 97

Range = Maximum - Minimum

Range = 97 - 26 = 71

Based on the values, we can say that

Option A) Jersey numbers are nominal data that are just replacements for names, so the resulting statistics are meaningless.

mark just bought a new vacuum cleaner for $220. he used a 30% off coupon and then paid 5.1% sales tax. what was his final cost?

MissTica

Answer: $161.85

Step-by-step explanation: $220 is the original price. you want to first deduct the 30% tax. Find out the 30% tax by multiplying 220 x .30 = 66. So deduct the $66 from $220 to get $154. That is the price. You will need to add on the 5.1% tax. So to get the tax you multiply $154 by .051 to get $7.854. Add that to the $154 sales price to get a total of $161.854. But since money, you can't have a portion of a cent so you round the 4 down
