Step-by-step explanation:
small triangle is similar to larger one
set up a proportion: 9 = x + 4
9+12 x+4+2x
9 = x+ 4 cross-multiply: 9(3x + 4) = 21(x + 4)
21 3x + 4 27x + 36 = 21x + 84
6x + 36 = 84
6x = 48
x = 8

The two quantitative elements of process variation are: Select one: a. common cause and special cause b. median and variance c. central tendency and spread d. inspection and detection
Answers
Answer:
The two quantitative elements of process variation are:
a. common cause and special cause.
Step-by-step explanation:
When a process fails to follow the prescribed process pattern, with reduced productivity, higher costs, longer lead times, and late deliveries, a process variation has occurred. Thus, process variation is a leading cause of quality issues. There are common cause variation, which is inherent in the system itself, and special cause variation, which is caused by external factors outside of the system. Process variations can be reduced by reducing the common and special cause variations, among other steps.
A store in Melrose, Massachusetts advertised a 35-mm camera for $259.99 and a wide-angle lens for $89.99. What is the total purchase price if the state sales tax rate is 6 percent
Answers
Answer:
The total purchase price is $370.97.
Step-by-step explanation:
Given;
price of the 35-mm camera, = $259.99
price of the wide-angle lens = $89.99
TAX rate = 6% = 0.06
The total purchase price = 0.06($259.99 + $89.99) + ($259.99 + $89.99)
The total purchase price = $20.99 + 349.98
The total purchase price = $370.97
Therefore, the total purchase price is $370.97.

Step-by-step explanation:
it shows that the intercept is around halfway between 0 and 20, and the plots are not exactly at the 10s marks, if you look- June is supposed to be 6, but it’s closer to 66. since 6*11=66, i’d say 11x+12 is the answer.

In a certain town, 23% of males have a beard. In random samples of 25 men from
this town, what are the mean and standard deviation of the number of men with
a beard?
Answers
Answer:
Mean μ = 5.75
Standard deviation σ = 2.1041
Step-by-step explanation:
Step(i):-
Given that the size of the sample 'n' = 25
Given proportion p= 23% = 0.23
Let 'X' be the random variable in a binomial distribution
Mean μ = np = 25 × 0.23 = 5.75
Step(ii):-
Standard deviation
σ = √npq
σ = [tex]\sqrt{25 X 0.23 X0.77}[/tex]
σ = 2.1041

You charge 2500 to a credit card. Use the compound interest formula to find the new amount you owe on your credit card after 6 months 20% APR compounded daily (assuming you don’t make any payments)
Answers
Answer: Well This is what 24% APR on a credit card is?
If you have a credit card with a 24% APR, that's the rate you're charged over 12 months, which comes out to 2% per month. Since months vary in length, credit cards break down APR even further into a daily periodic rate (DPR). It's the APR divided by 365, which would be 0.065% per day for a card with 24% APR.

Simplify sin θ/cosθ tan θ to a number or a single trigonometric function
Answers
Answer:
The answer is below
Step-by-step explanation:
Trigonometric functions are functions used in right angled triangles to relate an angle in the triangle to the ratio of two side. The most common trigonometric functions are the sine, the cosine, and the tangent.
Some trigonometric identities are:
secθ = 1/ cosθ, cosecθ = 1 / sinθ, tanθ = sinθ / cosθ, cotθ = 1 / tanθ = cosθ / sinθ.
Hence simplifying the question:
[tex]\frac{sin\theta}{cos\theta tan\theta} =\frac{sin\theta}{cos\theta *\frac{sin\theta}{cos\theta} }\\\\=\frac{sin\theta}{sin\theta}\\\\=1[/tex]

f(x)=x^2+8x-10 find f(a)+5
Answers
Answer:
We conclude that:
f(a) + 5 = a² + 8a - 5
Step-by-step explanation:
Given
The function is given by
f(x) = x²+8x-10
To determine
f(a)+5
In order to determine f(a)+5, first, we need to determine f(a).
Now substitute x = a in the function f(x) = x²+8x-10
f(a) = (a)² + 8(a) - 10
f(a) = a² + 8a - 10
Thus,
f(a) + 5 = (a² + 8a - 10) + 5
f(a) + 5 = a² + 8a - 5
Therefore, we conclude that:
f(a) + 5 = a² + 8a - 5
