First you subtract 8x to both sides so you get
2y=-8x+ 70
then you divide 2 with everything to get y by itself
-4x+35=y

Is Y=x you would change 2y to 2x

you would combine 8x+2x=10x

You are now left with 10x=70

Now you would divide 10 from both sides to get x=7

Find the range and interquartile range (IQR) of the data set in the box plot.
Eduardwww [97]

Answer:

Range = 23

IQR= 14.5

Step-by-step explanation:

Range is the biggest number- smallest number

so 30-7=23

IQR - Interquartile range = upper quartile - lower quartile

Lakima has a spinner divided into 5 equal sections that are labeled 1 though 5. She wants to compare the theoretical probability
Scrat [10]

Using probability concepts, it is found that:

  • The theoretical probability of spinning an odd number is equal to 3/5 = 0.6.
  • The experimental probability of spinning an odd number is equal to 1/2 = 0.5.
  • Therefore, the theoretical probability of spinning an odd number is greater than the experimental probability of spinning an odd number.

<h3>What is a probability?</h3>

A probability is given by the <u>number of desired outcomes divided by the number of total outcomes</u>.

A theoretical probability is calculated without considering experiments, and we have that 3 out of the 5 numbers(1,3,5) and are odd, hence the theoretical probability is given by:

pT = 3/5 = 0.6.

For an experimental probability, we consider the experiments. Of the 6 spins, 3 resulted in an odd number, hence the experimental probability is given by:

p = 3/6 = 1/2 = 0.5.

Therefore, the theoretical probability of spinning an odd number is greater than the experimental probability of spinning an odd number.

The means and mean absolute deviations of the individual times of members on two 4 times 400 meter relay track teams are shown i
Yakvenalex [24]

The correct answer is option C which is the ratio of the difference in the means of the two teams to the mean absolute deviation of Team B will be 0.25.

<h3>What is mean?</h3>

Mean is defined as the ratio of the sum of the number of the data sets to the total number of the data.

The difference between the mean times is about 16 times the mean absolute deviation of the data set.

59.32 - 59.1 = 0.22

2.4 - 1.5 = 0.9

0.22 / 0.9 = 0.25

Therefore the correct answer is option C which is the ratio of the difference in the means of the two teams to the mean absolute deviation of Team B will be 0.25.
