How many years are in 525,000 minutes? Round to the nearest whole.

Answer:
About 1 year
Step-by-step explanation:
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

Which of the following has a graph that is a straight line?
Equation 1: y = 4x3 + 6
Equation 2: y = 5x − 4.5
Equation 3: y2 = x − 1
Equation 4: y = 2x2 + 6
Answer:
Equation 2: y= 5x - 4.5
Step-by-step explanation:
This is a correct linear function. I would think this equation is linear because it goes by the f(x)=mx+b formula.
Answer: It would be equation B!

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

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.

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]
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]
Find the measure of angle B in triangle ABC below.Explain
Answer:
B ≈ 76°
Step-by-step explanation:
∆ABC is a right triangle
Reference angle = B
AC = 8 units = Opposite
BC = 4 units = Adjacent
Thus, apply TOA:
Tan B = Opp/Adj
Tan B = 8/2
Tan B = 4
B = Tan^{-1}(4)
B ≈ 76°
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

What is the value of x in simplest radical form?
Answer:
x = 85
Step-by-step explanation:
Because this is a right triangle, we can use the Pythagorean Theorem:
a² + b² = c²
Where c is the hypotenuse, or the longest side. This is opposite to the right angle of the right triangle. So now you have:
84² + 13² = x²
7056 + 169 = x²
7225 = x²
√7225 = √x²
85 = x
x = 85
