Fractions can be converted to percents. For example, 4/8 can be expressed as 50%. Write 6/8 as a percent.
Answer: 75%
Step-by-step explanation: First, you have to divide the numerator (6) by the denominator (8), which equals 0.75 in this case. Then you have to multiply the decimal (0.75) by 100. So you get the answer 75%.

The linear regression equation model obtained from the online regression equation is :
y = 0.75x + 5 ; where ;
y = weekly sales ; x = test score ; 0.75 = slope / gradient ; 5 = intercept
sales if the test score of a salesman is 65.
y = 0.75x + 5
x = 65
y = 0.75(65) + 5
y = 48.75 + 5
y = 53.75

Jenny bought gas for her car. Gas cost $3.45 per gallon. She bought 12.2 gallons for her car. What was the total cost of gas for Jenny's car?
Answer:
42.09
Step-by-step explanation:
3.45 x 12.2 = 42.09 (checked with a calculator)
2 x {6 + (12 = (3 + 1)]} – 1
Help please
Step-by-step explanation:
2×{(6+12)=(3+1)}-1
We will have to solve the ones in the bracket first.
2×{(18)=(3+1)}-1
2×{18=4}-1
So now we remove the brackets
2×18=4-1
36=3
Then we divide both sides by 3
So the final answer is 12

Find the PE ratio. Round to the nearest whole number.
Stock: Crown
Current Price per Share: $32.59
Annual Net Earnings per Share: $9.06
Answer:
4
Step-by-step explanation:
The current price per share is $32.59
The annual net earnings per share is $9.06
Therefore the PE ratio can be calculated as follows
= $32.59/$9.06
= 3.59
= 4 (to the nearest whole number)
Hence the PE ratio is 4
It is the end of the semester, and the clubs at school are recording their profits. The Science Club started out with $20 and has increased its balance by an average of $10 per week. Write an equation in slope intercept form for the Science Club. It is the end of the semester, and the clubs at school are recording their profits. The Math Club has saved $5 per week after starting out with $50 at the beginning of the semester. Write an equation in slope intercept form for the Math Club. It is the end of the semester, and the clubs at school are recording their profits. Graph both lines from question 1 and 2 on the same coordinate plane. When do the clubs have the same balance?
Answer:
Science Club- y=10x+20
Math Club- y=5x+50
They will be equal 6 weeks
Step-by-step explanation:
X equals the number of weeks that have passed. In example of the science club, they would gain $10 every week, making the equation y (total money) equal to 10 dollars a week (or 10x.)
Since we know they begin with 20 dollars, we'll simply add that to the 10 dollars a week.
To find the week when they will be equal, we have to put both equations equal to each other.
10x+20=5x+50
Now we solve for x, or the number of weeks when the equations (and values) will be equal.
10x+20=5x+50
5x+20=50
5x=30
x=6
So... 6 weeks :)

Beams fabricated by process A have flaw rates of 10/meter while beams fabricated by process B have flaw rates of 5/meter. From a yard containing equal numbers of process A and process B beams one beam is selected at random and a 1-meter length of the beam is inspected. If 8 flaws are found what is the probability the inspected beam was fabricated using process A?
Answer:
P(A | Y = 8) = 0.633
Step-by-step explanation:
It is really a simple and interesting question, as it involves the Poisson distribution and probability.
First of all, let's try to understand the problem statement clearly. It says that there are two process by which beams are made, namely A and B.
It further states that, beam made by process A has = 10 flaws per meter.
Beam made by process B has = 5 flaws per meter.
Finally, it says that from a yard containing equal numbers of process A and process B beans, one beam is randomly selected and 1 - meter of it is inspected. And they have found 8 flaws in it.
We now, have to find out the probability that the inspected beam is from process A.
For this,
Let's suppose, Y is no. of flaws
So,
P (Y=8|A) = [tex]\frac{e^{-10}. 10^{8} }{8!}[/tex]
where , e = Euler's Constant = 2.71828
P (Y=8|A) = 0.11
Similarly for process B
P (Y=8|B) = [tex]\frac{e^{-5}. 5^{8} }{8!}[/tex]
P (Y=8|B) = 0.06
As, we know from the problem statement that there are equal numbers of process A and process B beams.
So, the probability of A = Probability of B = 0.5
P(A) = 0.5
P(B) = 0.5
We need to find, P(A|Y=8) and for this we need to find the P(Y=8) first.
Using the law of total probability:
P(Y=8) = P(Y = 8 |A) P(A) + P(Y = 8|B) P(B)
Plug in the values:
P(Y=8) = (0.11 x 0.5) + (0.06 x 0.5)
P(Y=8) = 0.088
Now, by applying Bayes Theorem, we can find the required probability:
P(A | Y = 8) = P(Y = 8 | A) P(A) / P(Y = 8)
8 flaws are found, the probability the inspected beam was fabricated using process A is :
P(A | Y = 8) = 0.11 x 0.5 / 0.088
P(A | Y = 8) = 0.633
Furthermore,
8 flaws are found, the probability the inspected beam was fabricated using process B is :
P(B | Y = 8) = 1-P(A | Y = 8)
P(B | Y = 8) = 1 - 0.633
P(B | Y = 8) = 0.367

what is the range of the function f (x)= -1/3 lx-1l-2?
Answer:
All real values less than or equal to -2 or (infinity, -2].
Step-by-step explanation:
The range of the function is the range of what the output can be. Let’s analyze the equation in parts.
Notice that |x-1| must always be greater than or equal to 0, so we know that 1/3|x-1| also must always be greater than or equal to 1/3*0 = 0.
With the negative, however, -1/3|x-1| must be less than or equal to -1/3*0 = 0.
Finally, we take the -2 into account. -1/3|x-1| - 2 must always be less than or equal to 0-2 = -2.
Therefore, the range is all real values less than or equal to -2, which can be written as (infinity, -2].
I hope this helps!
