A researcher wants to know if eating a mint affects whether people can distinguish between two popular orange juice brands. To c

onduct an experiment, the researcher places 50 participants in two groups. The treatment group will eat a mint before drinking a juice, while the control group will not eat a mint before drinking. Then the participants will guess the juice brand. To select the groups, the researcher labels each participant with a number and selects slips of paper labeled 1–50 from a bowl at random. The first 25 participants whose numbers are selected will be the treatment group, while the other 25 will be the control group.
The characteristics of the two groups

A should be roughly equivalent because both groups will have 25 participants.
B should be roughly equivalent because the participants were labeled and then randomly selected for the groups.
C might not be roughly equivalent because one group may contain people that drink more juice than the other group.
D might not be roughly equivalent because one group may contain more people that prefer a particular juice brand.

Andrew received a raise from $14,580.00 per year to $25,317.40 per year. He received
skelet666 [1.2K]

Answer:

Step-by-step explanation:

$25,317.40 is about 57.5% higher than $14,580.00

57% doesn't fit the answers you provided, so either something is missing in the question, or the numbers may be messed up, or the answer is just 57.5%.

A 2% raise would be $14,871.60 per year.

A 3% raise would be $15,017.40 per year.

A 7.4% raise would be $15,658.92 per year.

A 29% raise would be $18,808.20 per year.

I hope this helps

In triangle ABC, (angle A) is a right angle and (m angle B) = 45deg.
Ratling [72]
We can use the ratios for special triangles (see the attachment below). We'll be using the 45-45-90 triangle. We notice that side BC is equal to x \sqrt{2}, and side AC (x using the special right triangle) is equal to 16. We can therefore say that side BC is equal to 16 \sqrt{2} ft

What is the slope of the line created by this equation?<br> y-6 = -3(x--8)<br> Help!
aliya0001 [1]

Rewrite the equation in slope intercept form:

Y -6 = -3(x - -8)

Use the distributive property on the right side first:

Y -6 = -3x -24

Add 6 to both sides

Y = -3x -18

The slope is the number in front of the x variable.

Slope = -3

HELPP plz in. 17 thank u so much
sergij07 [2.7K]
In the table, you can see level 1 is 5 to the first power, level 2 is 5 to the second and go on. 
so in level 6 would be 5 to the sixth power
so the answer to first one is 5^6 
for the second question you should know that level 2 is 5^2 and level 6 is 5^6 so 5^6/5^2 = 5^4 is the answer :))))
I hope this is helpful
have a nice day

Formula for circumference
Licemer1 [7]

Answer:

pi x diameter

Step-by-step explanation:

To calculate the circumference of a circle, simply multiply pi (3.14) by the diameter (straight line passing from side to side through the center of the circle)

For instance, if you knew the diameter of a circle was 6 inches. Simply multiply 6 inches by pi!

6 x pi = ?

? approximately equals 18.85 inches.

The circumference of the circle would be 18.85 inches!

If you only have the radius of the circle, simply multiply it by two to get your diameter. Remember, the radius is just half the length of the diameter.

Hope this helps! :)
