Answer:
12:7
Step-by-step explanation:
From the diagram shown;
QS/PS = RT/PT
QS/PS = RT/PS+ST
QS/14 = RT/14+10
QS/14 = RT/24
14RT = 24QS
RT/QS = 24/14
RT/QS = 12/7
Hence the required ratio is 12:7

(x, y) = (12, -1)
Step-by-step explanation:
I find the simplest solution is often found using a graphing calculator.
(x, y) = (12, -1)
__
We notice that the coefficients of x are identical, so we can eliminate x by subtracting the first equation from the second.
(x +3y) -(x -2y) = (9) -(14)
5y = -5 . . . . simplify
y = -1 . . . . . divide by 5
x = 14 +2y = 14 +2(-1) . . . . using the first equation to find x

Suppose that you head an insurance company. Your most popular insurance policy has a premium of $600 and a deductible of $1,000. This insurance policy provides your state’s minimum coverage of $30,000 for injury or death to one person, $50,000 for injury or death to two or more people, and $10,000 for damage to property, which is called 30/50/10 coverage.
Assume that, on average, 2 of your 100 customers have an accident every year. One of the accidents causes damage to property and the other causes injury or death to one person. Both drivers file for the maximum claims. After paying the claims, will your company still profit from the premiums collected in a year? Explain your answer
Answers
Answer:
Yes they will profit $22,000
Step-by-step explanation:
First find total money:
100 customers * $600 premium
= $60,000
add deductibles ($1000) because they are paying for the accident:
=$62,000
Then find the subtractions:
"One of the accidents causes damage to property and the other causes injury or death to one person."
based on the 30/40/10 coverage:
-$30,000 for injury or death to One person
-$10,000 for property damage
62,000 - 40,000 = 22,000
Overall profit : $22,000
I think I did that right...
The company will earn the profit of $22,000.
Profit= $22,000.
What is insurance deductible ?The amount you pay for covered health care services before your insurance plan starts to pay.
It is given that:
Most popular premium= $600
According to question there is estimation of 100 person
Total money = 100 customers * $600 premium
= $60,000
The deductible amount is $1000 because they are paying for the accident.
So, the deductible amount is= $2000
Total deductible amount =$62,000
As one of the accidents causes damage to property and the other causes injury or death to one person.
So, based on 30/40/10 coverage there will be:
-$30,000 for injury or death to One person-$10,000 for property damageSo, the profit will be: 62,000 - 40,000
= $22,000
Overall profit : $22,000

If z = -1.3, mu=80, sigma=30 What is the actual data value? Round to 2 decimal places.
Answers
Step-by-step explanation: This simple confidence interval calculator uses a Z statistic and sample mean (M) to generate an interval estimate of a population mean (μ).
Note: You should only use this calculator if (a) your sample size is 30 or greater; and/or (b) you know the population standard deviation (σ), and use this instead of your sample's standard deviation (an unusual situation). If your data does not meet these requirements, consider using the t statistic to generate a confidence interval.
where:
M = sample mean
Z = Z statistic determined by confidence level
sM = standard error = √(s2/n)
As you can see, to perform this calculation you need to know your sample mean, the number of items in your sample, and your sample's standard deviation (or population's standard deviation if your sample size is smaller than 30). (If you need to calculate mean and standard deviation from a set of raw scores, you can do so using our descriptive statistics tools.)

Answers
basically for the pythagorean theorem you use the formula a^2 + b^2 = c^2
it works for right triangles, with a and being being sides of the triangles and c being the hypotenuse
therefore for this specific example, you plug in the side 4 and the hypotenuse 5:
a^2 + 4^2 = 5^2
a^2 + 16 = 25
a^2 = 9
a = 3

Answer:

Step-by-step explanation:
Given The samples:
X = 10.2, 9.7, 10.1, 10.3, 10.1, 10.3, 10.1, 9.8, 9.9, 10.4, 10.3, 10.5,11.2,11.3, 9.8
Using a calculator ;
Sample mean, xbar = 10.27
Sample standard deviation, s = 0.462
H0 : μ = 15
H1 : μ < 15
The test statistic :
(xbar - μ) ÷ (s/sqrt(n))
(10.27 - 15) / (0.462/sqrt(15))
-4.73 / 0.1192878
= - 39.65
Using the Pvalue form Tscore, calculator, df = 14
Pvalue = 0.000001,
Since, Pvalue < α ; then we reject the Null
Confidence interval :
Xbar ± Margin of error
Margin of Error = Tcritical * s/√n
TCritical at 95%, df = 14
Margin of Error = 2.145 * 0.462/sqrt(15) = 0.2559
Lower boundary :
10.27 - 0.2559 = 10.0141
Upper boundary :
10.27 + 0.2559 = 10.5259
(10.0141 ; 10.5259)
The true population means should reside within the interval

How to find the x-intercept of a quadratic function ?Let us assume f(x) [tex]=ax^{2} +bx+c[/tex], then to find the x-intercepts of this quadratic equation, let y = 0, i.e. [tex]ax^{2} +bx+c=0[/tex]
How to find zeros of the given function ?Given, f(x)= [tex]3x^{2} -5x-22[/tex], whose one zero is (-2,0)
Now, to find the x-intercepts of the given quadratic equation, we have to take y = 0.
∴ [tex]3x^{2} -5x-22=0[/tex]
Now we have to solve this equation to find it's another zero.
[tex]3x^{2} -5x-22=0[/tex]
⇒ [tex]3x^{2} -(11-6)x-22=0[/tex]
⇒ [tex]3x^{2} -11x+6x-22=0[/tex]
⇒ [tex]x(3x-11)+2(3x-11)=0[/tex]
⇒ [tex](3x-11)(x+2)=0[/tex]
We know that, if multiplication of two terms is zero, then each of this term is seperately zero.
∴ [tex]3x-11=0[/tex] or [tex]x+2=0[/tex]
⇒ [tex]3x=11[/tex] or [tex]x=-2[/tex]
⇒ [tex]x=\frac{11}{3}[/tex] or [tex]x=-2[/tex]
So, another zero of the function is [tex](\frac{11}{3}, 0)[/tex].

Question #6
Show steps
Correct answer is A
Answers
We'll first need to determine what the composite function f(g(x)) is equal to.
Start with the outer function f(x). Then replace every copy of x with g(x). Afterward, plug in g(x) = 3x-2
So we get the following:
[tex]f(x) = \sqrt{x^2-4}\\\\f(g(x)) = \sqrt{(g(x))^2-4}\\\\f(g(x)) = \sqrt{(3x-2)^2-4}\\\\f(g(x)) = \sqrt{9x^2-12x+4-4}\\\\f(g(x)) = \sqrt{9x^2-12x}\\\\[/tex]
Next, we apply the derivative
[tex]f(g(x)) = \sqrt{9x^2-12x}\\\\f(g(x)) = (9x^2-12x)^{1/2}\\\\f'(g(x)) = \frac{1}{2}(9x^2-12x)^{-1/2}*\frac{d}{dx}(9x^2-12x)\\\\f'(g(x)) = \frac{1}{2}(9x^2-12x)^{-1/2}*(18x-12)\\\\f'(g(x)) = \frac{9x-6}{\sqrt{9x^2-12x}}\\\\[/tex]
Don't forget about the chain rule. The chain rule is applied in step 3 of that block of steps shown above.
The last thing we do is plug in x = 3 and simplify.
[tex]f'(g(x)) = \frac{9x-6}{\sqrt{9x^2-12x}}\\\\f'(g(3)) = \frac{9*3-6}{\sqrt{9*3^2-12*3}}\\\\f'(g(3)) = \frac{21}{\sqrt{45}}\\\\f'(g(3)) = \frac{21}{\sqrt{9*5}}\\\\f'(g(3)) = \frac{21}{\sqrt{9}*\sqrt{5}}\\\\f'(g(3)) = \frac{21}{3*\sqrt{5}}\\\\f'(g(3)) = \frac{7}{\sqrt{5}}\\\\[/tex]
Side note: if you choose to rationalize the denominator, then you'll multiply both top and bottom by sqrt(5) to end up with [tex]f'(g(3)) = \frac{7\sqrt{5}}{5}\\\\[/tex]; however, your teacher has chosen not to rationalize the denominator.

6) C because there are 6 numbers altogether and 1 6s on a dice so 6+6 because we have two dice and 2 6s on both so 2/12 or simplified 1/6
7) D because mean is all the numbers add up divided by the amount of numbers so 20+25+30+20+30 = 125 and 125 ÷ 5 = 25
8 B because mean is all the numbers add up divided by the amount of numbers so
5+6+7+8+8+8+8+8+8+9+9 = 76 ÷ by 10 is 7.6
7+7+7+7+8+8+8+8+10+10 = 80 ÷ by 10 = 8

Prices of: 41, 38, 19, 30, 21, 53, 34, 34, 37, 29, 50, 43, 57, 28, 50
The average is:
[tex]M = \frac{41 + 38 + 19 + 30 + 21 + 53 + 34 + 34 + 37 + 29 + 50 + 43 + 57 + 28 + 50}{15} = 37.6[/tex]
The average spent at his store is of $37.60.
Store of the competitor:
15 orders
Prices of: 86, 15, 75, 40, 51, 60, 27, 45, 112, 7, 65, 31, 18, 27, 69
The average is:
[tex]M = \frac{86 + 15 + 75 + 40 + 51 + 60 + 27 + 45 + 112 + 7 + 65 + 31 + 18 + 27 + 69}{15} = 48.53[/tex]

Answer:
a) Manager's store: mean = $37.60
