Hello :)
In 8 years, the father will be 2 times older than the child.
In 8 years, the father will be 40
In 8 years, the child will be 20
40 ÷ 20 = 2
So again, the answer is 8 years :)
Hope this helps and have a great day
Answer:
(e) 0.75
Step-by-step explanation:
The correlation coefficient is not affected by translation or scaling of scores. Converting them from "raw scores" to z-scores does not affect their correlation.
The correlation coefficient of the z-scores is 0.75.
Answer:
No. Remember, a right angle must have a 90 degree angle. We can find the lengths with the Pythagorean Theorem.
Step-by-step explanation:
Given the length 7, 10, and 12, we can assume that 12 is the hypotenuse (it is the longest length).
- we can use 7 and 10 interchangeably.
Fill in the equation, 
where c = 12, and a or b = 7 or 10.
To indicate if the given lengths would form a right angle, we can only input 7 or 10, not both.
Therefore, 
or 
==> 49 + b^2 = 144 ==> <u>b= </u>
<u> ==> </u><u>9.746</u>
b= 9.7, not 10.
==> 100 + b^2 = 144 ==> <u>b = </u>
<u> ==> </u><u>6.633 </u>
b= 6.6, not 7.
Therefore, the lengths 7, 10, and 12, does NOT make a right triangle.
Hope this helps!

Answer:
Last part 24x
Step-by-step explanation:
I understand some of this, like the last question. if each class had 24 pupil, and were trying to find out how many are in each class, it would be 24x (x stands for the amount of classes)
You have not given a true amount of pupils so I can not give a 100% correct answer for the first part.
