kareem is paid 72 for working 8 hours how much would he have been paid to work only 5 hours
Answer:
If Kareem were to work for 5 hours, she would get paid $45.
Step-by-step explanation:
If she gets paid $72 for working 8 hours, you would need to find how much she gets paid per hour by doing [tex]72/8[/tex].
Which then gives you $9 per hour, so then all you need to do is multiply $9 by the number of hours which in this case is 5 to get the answer of $45.
Clarissa has a bag of marbles. 9 are blue, 5 dre yellow, 2 dre purple, and 4 are green. What is the probability Clarissa reaches in the bag and pulls out a yellow marble, and then without replacing it, pulls out a marble that is not blue?
Answer:
Step-by-step explanation:
So, first lets the probability of just finding a yellow marble. There are 9+5+2+4 marbles in total, and that is 19 marbles.
5 out of those 20 are yellow, so the probabilty is 5/20 which is 1/4 or 20%
Then, lets do just finding the probability of a color that isn't blue.
Out of 20 marbles, 11 are color not blue, and 9 are.
So that probability is 11/20
Now, I think we need to do 11/20-5/20 so 6/20=3/10
Im so sorry, I might be wrong. I found both probabilities but I dont know if my final step is right.
Malik completes 0.7 of the total number of push-ups his coach requires. Which does NOT represent the part of the push-ups Malik completes? Please help I really need your help!!!
7%
14/20
70%
0.70
Answer:
7% does not represent the part 0.7 of the push-ups Malik completes because 7% is NOT equivalent to 0.7.
Step-by-step explanation:
Given that Malik completes 0.7 of the total number of push-ups his coach requires.
Checking the given options:
7% = 7/100 = 0.07
14/20 = 0.7
70% = 70/100 = 7/10 = 0.7
0.70 = 0.7
Therefore,
7% does not represent the part 0.7 of the push-ups Malik completes because 7% is NOT equivalent to 0.7.

i’m so confused i need to know the transformation but i don’t know what it is help may please
9514 1404 393
Answer:
2. K'(-1, -5)
3. (-3, 5), (3, 10), (-6, 8); translation left 2 and up 7
Step-by-step explanation:
2. The transformation is the one you have shown:
(x, y) ⇒ (x, -y) . . . . reflection over the x-axis
You are given the coordinates for K and asked for K', the reflected point. Use the x- and y-values in the transformation formula:
K(-1, 5) ⇒ K'(-1, -5) . . . . . . the y-coordinate is negated
It's that simple.
__
3. Same deal, different formula.
(x, y) ⇒ (x -2, y +7)
A(-1, -2) ⇒ A'(-1-2, -2+7) = A'(-3, 5)
B(5, 3) ⇒ B'(5 -2, 3 +7) = B'(3, 10)
C(-4, 1) ⇒ C'(-4 -2, 1 +7) = C'(-6, 8)
When constants are added to the coordinates, the transformation is a translation.
The x-values are decreased by 2, so that is a shift left by 2 units.
The y-values are increased by 7, so that is a shift up by 7 units.
The attachment shows the translated triangle (red). The translation vector (-2, 7) is shown as a black arrow. You will notice each triangle vertex is translated that length in that direction.
Given the following list of data, find the median. 3,18,11,36,23,5,8,15,32,22,16 Give your answer as a number only. For example, if you found the median was 20, you would enter 20.
Answer:
The median is 16.
Step-by-step explanation:
To find the median of a set, first we sort the set in an incresing way. So
3,5,8,11,15,16,18,22,23,32,36
The set has 11 elements, so the median will be element at the position (11+1)/2 = 6, that is, the 6th element of the sorted set.
In this case, the median is 16.

The graph shows y as a function of x:
In which segment is the function constant?
О А
O B
О C
O D
Answer:
A
Step-by-step explanation:
A constant line looks like a flat line with a slope of 0.
The segment that shows a constant function is segment A.
Option A is the correct answer.
What is a function?A function has an input and an output.
A function can be one-to-one or onto one.
It simply indicated the relationships between the input and the output.
Example:
f(x) = 2x + 1
f(1) = 2 + 1 = 3
f(2) = 2 x 2 + 1 = 4 + 1 = 5
The outputs of the functions are 3 and 5
The inputs of the function are 1 and 2.
We have,A function is constant if the graph is a straight line.
So,
From the given graph, we see that line A is a straight line.
This means,
Segment A shows a constant function.
Thus,
The segment that shows a constant function is segment A.

When the transmogrifiers are made at the factory, they move along a conveyer belt. Every 8th transmogrifier gets a blue control panel, every 3rd transmogrifier comes in green, and every 4th transmogrifier comes with a genuine Spaceman Spiff autographed photo.

The mean number of flight hours for Continental Airline pilots is 49 hours per month. Assume that this mean was based on a sample of 100 Continental pilots and that the sample standard deviation was 11.5 hours. Calculate the margin of error for a 95% confidence interval.
Answer:
The margin of error for a 95% confidence interval is of 2.18 hours.
Step-by-step explanation:
The first step to solve this problem is finding how many degrees of freedom, we have. This is the sample size subtracted by 1. So
df = 100 - 1 = 99
95% confidence interval
Now, we have to find a value of T, which is found looking at the t table, with 99 degrees of freedom(y-axis) and a confidence level of [tex]1 - \frac{1 - 0.95}{2} = 0.975[/tex]. So we have T = 1.984
The margin of error is:
[tex]M = T\frac{s}{\sqrt{n}}[/tex]
In which s is the standard deviation of the sample(square root of the variance) and n is the size of the sample.
In this question:
[tex]s = 11.5, n = 100[/tex]. So
[tex]M = T\frac{s}{\sqrt{n}}[/tex]
[tex]M = 1.984\frac{11}{\sqrt{100}}[/tex]
[tex]M = 2.18[/tex]
The margin of error for a 95% confidence interval is of 2.18 hours.

Answer:
$1.60 tip on a $8 sandwich
Step-by-step explanation:
SO to find percent
just multiply the number by the percent
Remeber the percent means x/100
SO in this case 20/100 or 1/5
So you can just multiply 1/5*8 and get 1 3/5.
If you convert 3/5 into a decimal
3 divided by 5
that is .6
SO add them up
1+0.6= $1.60
