It would be b because a^2+b^2=c^2 so in this case 5^2+8^2=c^2
The answer is 2.99 explanation is that I used my calculator lol
Answer:
x = 4
Step-by-step explanation:
3 x ( 4x -7 ) = 27
3 x 4x = 12x
3 x -7 = -21
12x -21 = 27
12x -21 + 21 = 27 + 21
12x = 48
12x/12 = 48/12
x = 4
This is a proportion problem. Eric earned 60 out of a possible 75 points, so the ratio is 60/75. You put that equal to x, so 60=x% and 75=100%. So it would look like
<u>60</u> = <u> x </u><u>
</u>75<u /> 100
then you cross multiply 60 and 100, and 75 and x, so you get
6000=75x
then divide by 75 and you have your percent :)
Answer: The value of test statistic is 0.696.
Step-by-step explanation:
Since we have given that
Similarly,
At 0.01 level of significance.
Hypothesis are :
So, the test statistic value would be
Hence, the value of test statistic is 0.696.
