Answer:
Confidence interval = 48±4
Step-by-step explanation:
Given:
Mean X = 48
Standard deviation sd = 14.1
Computation:
Z table value of 90% = 1.645
Total number n = 33
Computation:
Margin of error M.E = Z[sd/√n]
Margin of error M.E = 4 approx.
Confidence interval = 48±4
Answer:
6 with multiplicity 2
-2 with multiplicity 2
Step-by-step explanation:
We have given that find the roots of:
f (x) = (x- 6)²(x + 2)²
Note that the polynomials are already in the factored form. So we will only make it equal to zero
(x-6)² = 0
The square tells us that the root repeat twice
Move -6 to the R.H.S
Then,
x=6 , 6
(x+2)²=0
Move 2 to the R.H.S
Then,
x= -2, -2
Therefore the correct options are:
6 with multiplicity 2
-2 with multiplicity 2 ....
Divide 16/2 to get 8. Then multiply 3.14 x 8 x 8. That gives you 200.96 m. Hope this helps!
Answer:
0.54 ounces in each tube
Step-by-step explanation:
Add the amount she used so we can add it in. 1.35+0.27= 1.62. Then divide it by the number of tube and since it was a 3 pack you divide it by 3. 1.62/3=0.54 so there is 0.54 ounces in each tube.
