Answer:
C.)
Step-by-step explanation:
Since we are given the radius of the cone's base and the slant height, we can use the following equation to solve for surface area:
Now we just plug in the given information and solve:
Answer:
x=2, y=3
Step-by-step explanation:
y = 3
3x-y =3
Substitute y =3 into the second equation
3x -3 =3
Add 3 to each side
3x-3+3 = 3+3
3x=6
Divide by 3
3x/3 = 6/3
x =2
1. D none of the above.
2. A 5.43, 5.62, 5.74
3. A 75%
4. A 87.5%
5. A 0.7
6. B between 0.5 and 1.0
Answer:
The training does reduce response time at 0.05 level of significance
Step-by-step explanation:
Population mean for a population with normal distribution, where the standard deviation is known and the appropriate significant test is given then;
z=x-μ / δ/√n
where
μ= 9 minutes
x=8 minutes
δ= 4.2
n= 36
Applying the formula;
z= 8-9 / 4.2/√36
z= -1 / 4.2/6
z= -1 /0.7 = - 1.429
Perform the test where
H₀ : p=0.05 verse Ha : p < 0.05
Using the Z-table, find the probability that Z is less than -1.43.
You will find the probability of 0.0764 of Z being more than the value in test thus; there are high chances that results will be observed according to the null hypothesis
Answer:
f(1) = 4
Step-by-step explanation:
f(1) = 3(1)^2 -(1) + 2 = 4
Just replace all the x's with 1.
