Which of the following statements are true?Check all that apply.
The mean is affected by outliers.
The mean is always a more accurate measure of center than the median.
Removing an outlier from a data set will cause the standard deviation to increase.
If a data set’s distribution is skewed, then 95% of its values will fall between two standard deviations of the mean.
If a data set’s distribution to skewed to the right, its mean will be larger than its median.

Answers

Rob cuts 15-foot wire into 8 equal pieces. About how long is each piece

Answers

Answer

1.857

Explanation

The wire is 15 foot. Rop is to get 8 pieces.

If you are to get the length of each piece, we divide 15 by 8.

15 ÷ 8 = 15/8

= 1.875 foot

1.875 feet each. 1.875* 6= 15

Michael's favorite song is 3.19 minutes long. If he listens to the song 15 times on repeat, how long will he have listened to the same song?

Answers

Answer: 3.19x15=47.85

If you multiply 3.19 by 15 which is the amount of times he played the song, 47.85 minutes would be the amount of time that he has listened the song for so the answer would be 47.85

In triangle XYZ, angle Z is a right angle. If sinX = 3/4, find tan Y.

Answers

ANSWER

${ \tan(y) } = ( √(7) )/(3)$

EXPLANATION

$\sin(X )= (3)/(4)$

$\sin(X )= (opposite)/(hypotenuse)$

This implies that the opposite is 3 units and the hypotenuse is 4 units.

We now find the adjacent side using the Pythagoras Theorem.

${a}^(2) + {o}^(2) = {h}^(2)$

${a}^(2) + {3}^(2) = {4}^(2)$

${a}^(2) + 9 =16$

${a}^(2) =16 - 9$

${a}^(2) = 7$

${a}= √(7)$

${ \tan(y) } = (opposite)/(adjacent)$

The side opposite to Y is √7 and the side adjacent to Y is 3.

${ \tan(y) } = ( √(7) )/(3)$

How can you use a rate to compare the cost of two boxes of cereal that are different sizes

Answers

Answer:

Step-by-step explanation:

I think it is quite simple

Step 1. Find out the cost per ounce.

Step 2. Divide the cost of the box by the number of ounces.

hope this will find you well!

I know of one way, but I'm not sure if this is what you're looking for. Let me give an example to help:

I have 2 cereal boxes. One that weighs 10oz and cost $5, and another that weighed 6oz and cost $2. To compare them, you'd create ratios. I'll do oz/$

$(10)/(5)$ & $(6)/(2)$
Simplify. You should get 2 and 3. Now we know that the 10oz for $5 is a better deal than 6oz for $2.
