Answer:
Kindly check explanation
Step-by-step explanation:
xbar = 2.6
Sample size, n = 100
s = 0.4
Mean, μ = 4
The test statistic :
(xbar - μ) ÷ s/sqrt(n)
(2.6 - 4) ÷ 0.4/sqrt(25)
1.4 ÷ 0.08
= −17.5
Critical tvalue for 95% confidence interval :
df = n - 1 = 25 - 1 = 24
Tcritical at 0.05/2; df
Tcritical = ±2.064
Since, Tstatistic value does not fall within the Tcritical value ±2.064, we reject the Null
Using the p value from Tstatistic calculator :
P value at t = - 17.5 at 0.05 < 0.000001
Since p value is < 0.05, we reject H0.
Answer:
Step-by-step explanation:
x=55. Explanation: If x varies inversely as y , then that means: y=kx. Let's multiply both sides of the equation by x to find k . k=xy.
Answer:
B because (0,2) is your slope intercept, its the only table that has that coordinate pair
Step-by-step explanation:
Answer: option a.
Step-by-step explanation:
Given the expression 
, you need to remember:
The Product of powers property:
The Power of a power property:
And:
![\sqrt[n]{a^n}=a](https://tex.z-dn.net/?f=%5Csqrt%5Bn%5D%7Ba%5En%7D%3Da)
Therefore, as the index of the radical is 2, you can rewrite 
as:
Rewrite this and simplify. Then:
This matches with the option a.
