This is pretty easy and its not 3rd grade hw but whatever
First u do: 30 × 14 which = to 420
EXPLANATION:
If Sod covers 1-foot by 1-foot square then the amount needed will be need to be multiplied by the area of the yard and also 1
Answer: 420 peices
Hope this helped (If so please give brainliest, would really appreciate it)
Answer:
-4.
Step-by-step explanation:
2x^2 - 5xy - y^3
= 2(-3)^2 - 5(-3)(-2) - (-2)^3
= 2*9 - 5(-3)(-2) - (-8)
= 18 -5*6+ 8
= 18 - 30 + 8
= -12 + 8
= -4.
8. is A.
9. is A. -9
10. is x=3
11. is p=3
Hope this helps!! :)
Answer:
A) Null Hypothesis;H0: μ = 5
Alternative Hypothesis;Ha: μ ≠ 5
B) test statistic = -2.1226
C) p-value = 0.0598
D) Option A is correct
Step-by-step explanation:
We are given;
x = 4.52 minutes
s = 0.75 minutes
μ = 5 minutes
n = 11
degree of freedom = n - 1 = 11 - 1 = 10
A) The hypotheses are;
Null Hypothesis;H0: μ = 5
Alternative Hypothesis;Ha: μ ≠ 5
B) t-statistic = (x - μ)/(s/√n)
(4.52 - 5)/(0.75/√11) = -2.1226
C) From the t-score calculator results attached, the p-value is approximately 0.0598.
D) The P-value of 0.0598 is is greater than the significance level of 0.01, thus we fail to reject the null hypothesis, and we say that the result is statistically nonsignificant. So option A is correct.
