Mr. Johnson purchased 20 concert tickets for a total of $225. The concert tickets cost $15 for adults and $10 for children under twelve. How many tickets for children under twelve did Mr. Johnson purchase?

Answers

Answer:

15

Step-by-step explanation:

15a +10c=$225
a + c = 20
Rewrite the second equation so it has a value for c
c= 20 -a
Now using substitution method replace the c for the given value
15a + 10(20-a)=225
15a +200-10a=225
Combine like terms
5a +200=225
5a=25
a=5
So 5 adult tickets were bought and 15 children tickets

Knowing that correlation coefficients have values between -1 and 1 and that the closer the value is to -1 or 1, the stronger the correlation -- which of the following correlation coefficients would represent the strongest correlation?
0.02
0.87
-0.5
-0.97

Answers

Answer: -0.97

Explanation:
-0.97 is the closest number to -1 or 1.

-0.97 has the strongest correlation. Therefore, option D is the correct answer.

What is the correlation coefficient?

The correlation coefficient describes how one variable moves in relation to another. A positive correlation indicates that the two move in the same direction, with a value of 1 denoting a perfect positive correlation. A value of -1 shows a perfect negative, or inverse, correlation, while zero means no linear correlation exists.

Given that, correlation coefficients have values between -1 and 1 and that the closer the value is to -1 or 1, the stronger the correlation

From the options -0.97 is closer to -1

Thus, -0.97 has the strongest correlation

Therefore, option D is the correct answer.

Answers

Answer:

AC 4x + 16

Angle BEC is 72 degrees

Step-by-step explanation:

AE is 2x + 8, and AC is 2 times bigger, so 4x + 16

Angle EAD is the same as angle EDA, which is 54 degrees, a triangle has 3 sides measuring 180 degrees total, 54 + 54 = 108, so the last angle is 180 - 108 = 72, angle AED is 72, since angle BEC is the same as angle AED, it is also 72 degrees

In a wildlife preserve, a random sample of the population of 150 raccoons was caught and weighed. The results, given in pounds, were 17, 19, 20, 21, 23, 27, 28, 28, 28 and 32. Jean made the inference, "the average weight of the raccoon population is 25 pounds". Is this statement reasonable? Explain.

Answers

Answer:

    First you add all of the results together for a sum of 243. Then, you divide that sum, 243 by 10, the number of results in total. That means the average weight of 10 random raccoons out of 150 raccoons in that wildlife preserve, is 24.3 pounds. Her statement is not reasonable because Jean stated the average weight of ALL raccoons is 25 pounds.

Step-by-step explanation:

hope this helps :)

No, because the average weight of the raccoons is 24.3 pounds.

Step 1) 17+19+20+21+23+27+28+28+28+32=243

Step 2)
243 divided by 10 = 24.3pounds
