Answer:
The correct answer is A. It is constant.
Step-by-step explanation:
When the x-values are between 4 and 8, this graph is constant. This can be seen because the graph is a horizontal line, meaning it has zero slope. Since the slope is zero, it is neither increasing nor decreasing, and is known as constant.
Hope this helps!
Answer:
1310.8 feet^3 to nearest tenth.
Step-by-step explanation:
To find the volume we need to find the depth.
The length of the diagonal helps us to do this. We apply the Pythagoras theorem to the triangle formed by the length, the diagonal and the depth (d):
17.8^2 = d^2 + 16.6^2
d^2 = 17.8^2 - 16.6^2
d^2 = 41.28
So the depth d = 6.42 feet.
Thus, the volume = 16.6 * 12.3 * 6.42
= 1310.8 feet^3.
The average of the 3 grades = (81+85+95) /3
=87
This counts as 2/3
of the final grade:
87 * 2/3 = 58 points
For a grade of 90, they still need 90 -58 = 32 points
Let x = final exam score
The final exam is worth 1/3, so we get:
1/3x = 32
To get x, multiply both sides by 3:
x = 32 *3
x = 96
They need a 96 on the final exam.
Answer:
We accept H₀ , we do not have enought evidence for rejecting H₀
Step-by-step explanation:
Normal Distribution
sample size n = 60
standard deviation σ = 15
1.Hypothesis Test : Is a one tailed-test on the right
H₀ null hypothesis μ₀ = 50
Hₐ alternative hypothesis μ₀ > 50
2.-We will do the test for a significance level α = 0,01 tht means for a 99% interval of confidence
then z(c) = 2.32
3.- We compute z(s)
z(s) = [ ( μ - μ₀ ) /( σ/√n ) ⇒ z(s) = ( 2 * √60 ) / 15
z(s) = 15.49/15 ⇒ z(s) = 1.033
4.- We compare values of z(c) and z(s)
z(s) < z(c) 1.033 < 2.32
z(s) is in the acceptance region so we accept H₀ , we do not have enough evidence for rejecting H₀
Answer:
Just copy whatever the picture says. There is a name on each of your questions like a) and b) and c), so I will have that same thing too. LOOK AT PICTURE.
