Answer:

{1, 2, 4, 8}

Explanation:

The <em>range </em>in a set of ordered pairs is the set of the second number of the pairs (the y-coordinates).

In the set of points {(-1,1),(0,2),(1,4),(2,8)}, the range is {1, 2, 4, 8}.

(ASAP NEED TO SUBMIT NOW!!!) What is the Unit Rate for each cyclist?

sveta [45]

Answer:

Unit rates for cyclist A , B, C , D are 12 mile/ hour , 5 mile/hour, 9 mile/hour and 10 mile/hour respectively. Cyclist A is the fastest among the four.

Step-by-step explanation:

Cyclist A can ride 24 miles in 2 hours

so, cyclist A's unit rate is, $\frac {24}{2}$

= 12 mile/hour

Cyclist B's unit rate is, $\frac {5}{1}$

= $\frac {10}{2}$

= $\frac {15}{3}$

= 5 mile/hour

Equation for cyclist C is, y = 9x ,

so, cyclist C's unit rate is , 9 mile/hour

Slope of the graph for cyclist D,

= $\frac {10 -0}{1 - 0}$

= 10

So cyclist D's unit rate is, 10 mile/hour

So, cyclist A is the fastest.

a company wants to study the effectiveness of a new pain relief medicine. they recruit 100100100 volunteers with chronic pain. e

Andrej [43]

Completely random design is used in this experiment.

In the given question,

A business wants to investigate the efficacy of a novel painkiller.

100 participants who suffer from chronic discomfort are enlisted.

Each participant takes the brand-new painkiller for two weeks before switching to a placebo for an additional two weeks.

The order of the tablets is chosen at random for each participant, and the subjects are unaware of which pill contains the actual medication.

Each subject's variance in total pain will be measured by researchers.

We have to check what type of experiment design is this.

As we can see in the question that they recruit 100 volunteers with chronic pain and each subject they use new pain relief medicine for a 2-week period and a placebo for another 2-week period.

They assign each subject randomly.

As we know that in a completely random design, treatments are randomly assigned to sampling material. The usual method for doing this is to make a list of the treatments and give each one a random number.

So we can see that completely random design is used in this experiment.

A box is 12 centimeters wide ,12 centimeters long, and 15 centimeters tall. What is the total surface area of 4 such boxes?

Grace [21]

First you want to find the surface area of one box
SA=2(l*w)+2(h*l)+2(h*w)
SA=2(12*12)+2(15*12)+2(15*12)
SA=2(144)+2(180)+2(180)
SA=288+360+360
SA=1008 cm² is for one box
Multiply by 4 to get for 4 boxes
4*1008=4032 cm²
