Members of the Video Digital club produce short videos. At the end
of each school year, the club hosts a Video Digital festival at a local
theater to show the community its top 25 videos.
Part A:
The club has realized from experience that when they don't charge
for admission, 800 people come. For every dollar they charge for
admission, 8 fewer people come. Write an inequality that they can
use to determine the price, p, in dollars that the club must charge for
at least 750 to come to the video festival

is AB tangent to the circle?
Answer:
Yes, AB is tangent to the circle
Step-by-step explanation:
If AB is tangent to the circle, the triangle will be a right triangle, so if:
11.4² + 15.2² = 19²
129.96 + 231.04 = 361
361 = 361
so it is tangent

Answer:
33.49 ft³
Step-by-step explanation:
Use the formula for the volume of a sphere and fill in the given numbers. After that, it's all arithmetic. A calculator is usually helpful.
[tex]V=\dfrac{4}{3}\pi r^3\\\\V=\dfrac{4}{3}(3.14)(2\text{ ft})^3=\dfrac{(4)(3.14)(8)}{3}\text{ ft}^3\\\\=\boxed{33.49\text{ ft}^3}[/tex]

A certain process for manufacturing integrated circuits has been in use for a period of time, and it is known that 12% of the circuits it produces are defective. A new process that is supposed to reduce the proportion of defectives is being tested. In a simple random sample of 100 circuits produced by the new process, 11 were defective.
a. If the proportion of defectives in the sample is less than 12%, it is reasonable to conclude that the new process is better.
1. True
2. False
b. If the proportion of defectives in the sample is only slightly less than 12%, the difference could be due entirely to sampling variation, and it's not reasonable to conclude that the new process is better.
1. True
2. False
c. If the proportion of defectives in the sample is a lot less than 12%, it is very unlikely that the difference is due entirely to sampling variation, so it is reasonable to conclude that the new process is better.
1. True
2. False
Answer:
a. If the proportion of defectives in the sample is only slightly less than 12%, the difference could be due entirely to sampling variation, and it's not reasonable to conclude that the new process is better
b. True
c. True
Step-by-step explanation:
a. The percentage of defective circuits produced = 12%
Given that the percentage of defective circuits produced in the new process is 11% which is only slightly less than the observed 12%, the difference may be due to variation in the sample, as another sample of 100 in the new process cold produce more than 11 defective circuits
b. True. In every sample, there is a slight variation which can account for the difference
c. Given that the defectives in the sample is considerably less than 12%, then it would be more statistically evident that there is a difference in the two processes and the new process can be considered reasonably better
Therefore, the answer is; True

what the total area of a rectangular prism with a hight of 17feet a width of 12 feet and a thickness of 10 feet ?
Answer:
988ft^2
Step-by-step explanation:
Total area of a rectangular prism = 2(lw+wh+lh)
length l = 17feet
width w = 12feet
thickness = 10feet
TSA = 2(17(12)+17(10) + 12(10))
TSA = 2(204+170+120)
TSA = 2(494)
TSA = 988ft^2
Hence the total surface area is 988ft^2
2) A farmer has a cylindrical silo he uses to store corn. The silo has a height of 50 feet and a
radius of 12 feet. How many cubic feet of corn can the silo hold? Use 3.14 for pi

Volume of Cylinder = πr²h
= 3.14 * 12 * 12 * 50
= 22608 cubic ft
Four families went out for lunch. The total food bill came to $220. The families also left a $30 tip for the waitress.
If each family spent the same amount, about how much did each family spend on dinner? Complete the explanation on how you found your answer.
First, add $
and $30 to find the total bill.
$
is between $
and $

C.
84.5 in
D.
20.41 in
Answer:
circumference=2πr=2×22/7×6.5=40.8571428571
option
A.
A.40.82 in
is your answer.

Recall the Akaike information Criterion (AIC) as well as the related Bayesian Information Criterion (BIC) from our study of Variable Selection and Model Building. Without heavy mathematical notation, explain how both the AIC and BIC emphasize goodness-of-fit of a regression model while also controlling model complexity. Why would we wish to do this (that is, to promote goodness-of-it while at the same time controlling model complexity)
Step-by-step explanation:
To check out how efficient or accurate a model is, we use the akaike information criterion or the Bayesian. If the AIC or BIC are lower, then this model would be better. They are also used to control for model complexity
Akaike information criterion = 2k-2ln where k is the number of parameter. A higher k gives a higher AIC.
In the real world complex models are discouraged and avoided since
1. They cause data to be over fitted and can capture noise and information from this data.
2. They are complex and therefore difficult to interpret
3. They consume a lot of time and computing them has several inefficiencies.
Using these two as measure of performance, we can select optimal choice of independent variable.
With forward/backward regression, we are able to put new variables in the model or remove from it. The best is the one with lowest AIC.

Randall enjoys canoeing. The time it takes for his canoe to go 3 miles upstream and back 3 miles downstream in a lake is 4 hours. The current of the lake is 1 miles per hour. Which equation can Randall use to determine the average speed of the canoe in still water?
The equation used to find the average speed is (a - 1)t₁ = 3, (a + 1)t₂ = 3 and t₁ + t₂ = 4.
SpeedSpeed is the ratio of total distance travelled to total time taken. It is given by:
Speed = distance / time
Let t₁ represent the time upstream and t₂ the time downstream while a represent the average speed of the canoe in still water.
Hence:
t₁ + t₂ = 4 (1)
Also:
(a - 1)t₁ = 3 (2)
(a + 1)t₂ = 3 (3)
The equation used to find the average speed is (a - 1)t₁ = 3, (a + 1)t₂ = 3 and t₁ + t₂ = 4.

cosA-sinA+1/cosA+sinA+1=1-sinA/cosA
Answer:
steps below
Step-by-step explanation:
(cosA-sinA+1) * cosA = cos²A - sinA cosA + cosA
= (1 - sin²A) - sinA cosA + cosA + sinA - sinA
= cosA + sinA + 1 - sinA cosA -sin²A - sinA ..Re-group
= (cosA + sinA + 1) - sinA (cosA + sinA + 1)
= (cosA + sinA + 1) * (1 - sinA)
(cosA-sinA+1) / (cosA + sinA + 1) = (1 - sinA) / cosA

Find the volume of the composite figure.
First, find the volume of the cylinder.
Use 3.14 for T. 9 cm
Cylinder Volume = [?] cm 8 cm 6 cm Rectangular Prism Volume = [ ]cm 8 cm 14 cm Total Volume of Composite Figure = [ ] cm3
Answer:
Volume for cylinder = 508.68 [tex]cm^{3}[/tex]
Volume of rectangular prism = 672 [tex]cm^{3}[/tex]
Total volume = 1180.68 [tex]cm^{3}[/tex]
Step-by-step explanation::
[tex]V = \pi r^{2} h[/tex] r = 4.5
= 3.14([tex]4.5^{2}[/tex]) (8) = 508.68
Volume for rectangular prism:
V = lwh = (14)(8)(6) = 672
Total volume = 508.68 + 672 = 1180.68 [tex]cm^{3}[/tex]
