Answer:
im not sure but i think it is $785.34
Step-by-step explanation:
srry if it is wrong :(
27pi
3/4 * r^2*pi = 36 * 3/4 * pi = 27 pi
Answer:
p-value: 0.453
Step-by-step explanation:
Hello!
You have two study variables
X~N(μₓ;σₓ²)
nₓ= 4
X[bar]ₓ= 149.50
Sₓ= 10.66
Y~N(μ;σ²)
= 6
X[bar]= 158.17
S= 19.87
The hypothesis is:
H₀: μₓ = μ
H₁: μₓ ≠ μ
The statistic to use is a pooled t for independent samples with unknown but equal population variances
t= [(X[bar]ₓ - X[bar]) - (μₓ - μ)]/[Sa/√(1/nₓ + 1/)]
The value of the statistic is:
t= -0.789
For this statistic value the corresponding p-value is:
P(t ≤ -0.789) + (1 - P(t ≤ 0.789) = 0.453
I hope it helps!
Answers:
- a) No, the figure would not look the same. See the diagram below
- b) Yes the figure would look the same after a half turn
- c) Yes the figure would look the same after a full turn
==================================================
Explanations:
- a) The figure doesn't have 90 degree symmetry, so that's why we have a different looking figure after a quarter turn.
- b) The figure does have 180 degree symmetry. That's why it looks the same after a half turn (aka 180 degree turn)
- c) Rotating any figure 360 degrees, aka a full turn, will get everything back where it started. It doesn't matter if the figure has any symmetry or not.

Step-by-step explanation:
y = 2x + 8
She know 8 songs. 8 will be the y-intercept and each month she learns 2 songs which will be the slope of the function.
