7.158 * 10^9 rounds to 7 * 10^9
7 * 10^9 = 7,000,000,000
You can use pythagorean theorem and square 1.5 and 6 and those added together is the hypotenuse (the slope) squared. the answer is approximately 6.2
Answer:
Reject the null hypothesis.
Step-by-step explanation:
n1 = 16
n2 = 21
S.V1 = 5.8
S.V2 = 2.4
= 0.05
= Population Variance 1 ≤ Population Variance 2
= Population Variance 1 > Population Variance 2
Test statistic value = 5.8 / 2.4 = 2.417
Degrees of freedom is n - 1
15 and 20
Critical value is
= 2.2
2.417 > 2.2
we reject the null hypothesis as the critical value is greater than the test statistic.
The answer is D because , 4x176 = 704 which you divide by 60 because thats how many minutes are in an hour which should come out to 11 hours
Multiply by z to get
wz = xy
divide by x
y = wz/x
