Answer:
60 minutes
Step-by-step explanation:
Ratio is 9:5
if that needed to go to 108:?
you multiply 9 by 12 to get 108, so u must do the same with the other side. 5*12 is 60. so this would be
108:60
Jace purchases a new motorcycle for $8000. The bike depreciates 12% every year.
Write two equations that models the price of the bike after 5 years.
Answer:
We know that the original price of the bike was $8,000.
After one year, the price of the bike decays a 12%, then the new price of the bike is:
P(1) = $8,000*( 1 - 12%/100%) = $8,000*(1 - 0.12)
After another year, the price again decays a 12%, the new price will be:
P(2) = $8,000*(1 - 0.12)*(1 - 12%/100%) = $8,000*(1 - 0.12)*(1 - 0.12) = $8,000*(1 - 0.12)^2
We already can see the pattern here, after t years, the price of the bike will be:
P(t) = $8,000*(1 - 0.12)^t
With this equation, we can find the price of the bike after 5 years, where we only need to replace t by 5
We will get:
P(5) = $8,000*(1 - 0.12)^5 = $4,221.9
The price of the bike after 5 years is $4,221.9.
Now we want two equations to represent this, so we need another.
This is kinda trivial, because there is only one equation that represents this, so we only can rewrite our equation in another form.
We could say that the price of the bike after t years is:
P(t) = $8,000*(0.88)^t
or something like:
P(t) = $7040*(0.88)^(t - 1)
Where i multiplied the initial value by 0.88, and then reduced the exponent by one.

According to the recent poll, 22 1/4% of the people polled said that they approved of the city plan to expand the library. If 1004 people was polled, about how many were in favor of the expansion?
Answer:
Some 224 people were in favor of the expansion.
Step-by-step explanation:
Given that, according to the recent poll, 22 1/4% of the people polled said that they approved of the city plan to expand the library, if 1004 people was polled, to determine how many were in favor of the expansion should be done the following calculation:
1/4 = 0.25
100 = 1004
22.25 = X
1004 x 22.25 / 100 = X
223.39 = X
Thus, some 224 people were in favor of the expansion.

the cost of the beam was _______per yard
Answer:
$27
Step-by-step explanation:
According to your question. The complete cost was $135 for a fifteen feet long beam. If you are looking for the price per yard, a yard has three feet, therefore in fifteen feet, there are five yards.
15 divided into 3 equals 5
$135 divided into five equals $27

Use a linear approximation (or differentials) to estimate the given number. (Round your answer to two decimal places.) (1.999)3
Consider the function f(x) = x ³. Since 2³ = 8 is a perfect cube that is pretty close to x = 1.999, take the linear approximation to f(x) at x = 2. It is
f(x) ≈ L(x) = f (2) + f ' (2) (x - 2)
Compute the derivative:
f(x) = x ³ → f ' (x) = 3x ² → f ' (2) = 12
Then
L(x) = 8 + 12 (x - 2) = 12x - 16
Now approximate 1.999³ :
f (1.999) ≈ L (1.999) = 12•1.999 - 16 = 7.988
(Compare this to the actual value, 7.98801.)

Answer:
242 ft²
Step-by-step explanation:
The shape can be decomposed to give us a trapezium and a rectangle
Area of the shape = area of the trapezium + area of the rectangle
✔️Area of the trapezium = ½(a + b)h
a = 14 ft
b = 20 ft
h = 13 - 7 = 6 ft
Area = ½(14 + 20)*6
Area of trapezium = 102 ft²
✔️Area of rectangle = L*W
L = 20 ft
W = 7 ft
Area = 20*7 = 140 ft²
✔️Area of the shape = 102 + 140 = 242 ft²

16 cm 2
48 cm 2
96 cm 2
80 cm 2
Answer:
Surface area = 80 cm²
Step-by-step explanation:
Surface Area of rectangular prism = 2(LW + LH + WH)
L = 4 cm
W = 4 cm
H = 3 cm
Plug in the values
Surface Area = 2(4*4 + 4*3 + 4*3) = 2(16 + 12 + 12)
Surface Area = 2(40) = 80 cm²

In a filling line at A & C Foods, Ltd., the mean fill volume for rice bubbles is 475 grams and the standard deviation is 10 grams. The design specifications are [450, 495] grams. Any output outside of design specifications is treated as non-conforming. (1) Calculate the dpmo of the process (by calculating the area of non-conformance). Please type your answer in integers.
Answer:
The dpmo of the process is of 29000
Step-by-step explanation:
Dpmo of a process:
The dpmo of a process is the number of defects per million opportunities.
Normal Probability Distribution:
Problems of normal distributions can be solved using the z-score formula.
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.
In this question:
First, using the normal distribution, we calculate the proportion of defective bubbles. Then, using this proportion, we calculate the dpmo.
Mean fill volume for rice bubbles is 475 grams and the standard deviation is 10 grams.
This means that [tex]\mu = 475, \sigma = 10[/tex]
The design specifications are [450, 495] grams. Any output outside of design specifications is treated as non-conforming.
Below 450 and Above 495 are non-conforming.
Below 450:
The proportion is the pvalue of Z when X = 450. So
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{450 - 475}{10}[/tex]
[tex]Z = -2.5[/tex]
[tex]Z = -2.5[/tex] has a pvalue of 0.0062
Above 495:
The proportion is 1 subtracted by the pvalue of Z when X = 495. So
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{495 - 475}{10}[/tex]
[tex]Z = 2[/tex]
[tex]Z = 2[/tex] has a pvalue of 0.9772
1 - 0.9772 = 0.0228
The proportion of defectives is 0.0228 + 0.0062 = 0.0290
Dpmo:
Number of defects per million, that is, the proportion multiplied by 1000000.
1000000*0.0290 = 29000
The dpmo of the process is of 29000
