Answer:
H0 : P = 0.72
H1 : P > 0.72
Step-by-step explanation:
Claim is to test that percentage of customers who leave a review is greater than 72%
From the information given :
P0 = 72/100 = 0.72
The null hypothesis, H0 : P = 0.72
Alternative hypothesis claims the proportion is greater than 0.72 and from the sampling result obtained, phat = 0.90
Hence,
Alternative hypothesis, H1 : P > 0.72

For each tank, explain whether or not there is a proportional relationship between
the amount of water, in gallons, and the time, in minutes. If there is a proportional
relationship, identify the unit rate. Use specific features of the graph to support
your answer
hp
Answer: Step-by-step explanation:
A proportional relationship exists. Since the graph is a straight line, you can say.
Tank A's unit rate is 666 2/3 gallons per minute. You'll figure it out by multiplying 1000 gallons by 1.5 minutes. 1000 divided by 1.5 equals 666.66 gallons, or 666 2/3 gallons.
The unit rate for Tank B is 300 gallons per minute. You can determine this by using 600 gallons in 2 minutes. 600/2 = 300 gallons per minutes
Please help me. Thank you very much. （╹◡╹）
Answer and Step-by-step explanation:
First, you find the x-value of f(x) on the graph, and find the corresponding y-value.
On the graph, we see that when we go to the x-value of -7, we are at a y-value of 0. Now, we plug this in to the g(x) function and look for the y-value on the g(x) graph.
When 0 is plugged in for x in g(x), we get the y-value to be 5.
This means that the value of g(f(-7)) is 5.

Answer:
A. y = 4.5x
Step-by-step explanation:
y is the length of the fish and x is the time, by checking each equation with values in the table you can see that this is the one that represents the relationship.
Example using (4 yrs, 18 cm):
A: 18 = 4.5(4) ✅
B: 4 = 4.5(18) ❌
C: 4 = 9(18) ❌
D: 18 = 9(4) ❌

Answer:
900 pi for first question and 14137 for 2nd
Step-by-step explanation:
SA=4pi r^2
r=15 (30/2)
SA=4pi(15^2)
SA=900pi
V=4/3pi r^3
V=4/3(3.14)(15^3)=14137
Answer:
Surface area: 900π in²
Volume: 4500π in³
Step-by-step explanation:
A = 4πr² = 4π(15²) = 900π
V = 4/3 πr³ = 4/3 π(15³) = 4500π
Someone helppp pls :(((((
Answer:
y = ½x + 8
Step-by-step explanation:
✔️First, find the slope (m) using any two given pairs of values, say (0, 8) and (2, 9):
Slope (m) = change in y/change in x
Slope (m) = (9 - 8)/(2 - 0)
Slope (m) = 1/2
m = ½
✔️Find the y-intercept (b):
The y-inteeceot of the function would be the value of y when x = 0.
Form the table, when x = 0, y = 8. Therefore:
y-intercept (b) = 8
✔️To write the equation of the function, substitute m = ½ and b = 8 into y = mx + b.
Thus:
y = ½x + 8

Answer:
B
Step-by-step explanation:
X ≥ 11 means that x could equal 11. The number is included on the answer. So, the circle on the number line has to be closed/filled in. X could be any number equal to or greater than 11, so the number line has to be shaded to the right. :D

Answer:
Q = 12 meters
Step-by-step explanation:
Since all angles of the triangles are the same, the two triangles are similar. Therefore, all you need to do is a simple comparison equation like 10/15=8/x and solve.
Cross multiply, 10x=120. Divide and get x = 12.
Hope this helps!
An isosceles triangle has an angle that measures 116°. Which other angles could be in that isosceles triangle? Choose all that apply.
Answer:
Step-by-step explanation:
since we know that triangles have 180° we know that 116° is two much if it's doubled 2*116 = 232° so that angle has to be the single angle and the left over of 180 - 116 is the left over amount that is even divided into the last two angles so 180 - 116 = 64 / 2 = 32° so the triangle is made up of 116 + 32 + 32 degree angles
