Answer:
Step-by-step explanation:
Given that:
Mean μ= 100
standard deviation σ = 2.6
sample size n = 9
sample mean X = 100.6
The null hypothesis and the alternative hypothesis can be computed as follows:


The numerical value for the test statistics is :



z = 0.6923
At ∝ = 0.05

The critical value for the z score = 0.2443
From the z table, area under the curve, the corresponding value which is less than the significant level of 0.05 is 1.64
P- value = 0.244
c> If the true population mean is 101.3 ;
Then:



z = 0.808
From the normal z tables
P value = 0.2096
Answer:
0
Step-by-step explanation:
First we have to identify 1/3 m. We know that m is 21 and 1/3 of 21 is 7.
Then we find 1/2 on n which we know is 12 so 1/2 of 12 is 6.
Then we subtract. 7-1 is 6 and 6-6 is 0
Hope this helped!!! :D
Answer:
408 in²
Step-by-step explanation:
A rectangular prism has 6 rectangular faces.
Opposite faces are congruent
2 faces at (6 × 9) = 2 × 54 = 108 in²
2 faces at (9 × 10) = 2 × 90 = 180 in²
2 faces at (6 × 10) = 2 × 60 = 120 in²
surface area = 108 + 180 + 120 = 408 in²
Take the f function minus the g function and subtract like terms
4 - (-2) is 6, so that part is 6*8 to the x power,
then you have the 18x with nothing subtracted from it,
and then -7 - -12....or at least that looks like -12...hard to see with it being covered up...anyway that part would be 5.
so 6*8^x + 18x + 5 is the answer
