If my pay rate is $9 an hour and I worked 7 hours and 45 minutes. How much money did I make?
Answer:
$69.75
Step-by-step explanation:
$9 x 7 = $63
45 min/60 min = 0.75
$9 x 0.75 = $6.75
$63 + $6.75 = $69.75
Answer:
$69.75
Step-by-step explanation:
$9 x 7 hours = $63
$9 x 3/4 = $6.75
$63 + $6.75 = $69.75

The intercepts of the line Y=-2x-21
Answer:
-21
Step-by-step explanation:
GIven data
We are given the equation of a line as
Y=-2x-21
let us compare this with the general equation of a line
y=mx+c
from the comparison, we can see that the intercept is -21
Therefore, the intercept is -21

Solve |3x + 9| + 6 = 6 Question 4 options: A) x = –3 B) x = 3 or x = –3 C) No solutions D) x = 3
Answer:
A) x = -3
Step-by-step explanation:
|3(-3) + 9| = 0
|-9 + 9| = 0
|0| = 0
0 = 0
Answer:
A)x=−3
Step-by-step explanation:
Step 1: Add -6 to both sides.
|3x+9|+6+−6=6+−6
|3x+9|=0
Step 2: Solve Absolute Value.
|3x+9|=0
We know 3x+9=0
3x+9=0(Possibility 1)
3x+9−9=0−9(Subtract 9 from both sides)
3x=−9
3x /3 = −9 /3
(Divide both sides by 3)
x=−3

There are 1420 students enrolled at Senn. If 60% of these students walk to school, how many students are walking to school?
I need an explanation also :)
Answer:
852 students walking to school
Step-by-step explanation:
Lets start with a simple example so you can get it
if 60% of 100 students walk to school that means
60 students walk to school... right??
so lets simplify it more that means you have multiplied 100 (students) by 60%
or [tex]\frac{60}{100}[/tex] (note: you can say that 60% is equal to [tex]\frac{60}{100}[/tex] )
so the problem told 60% of 1420 students walk to school that means we should
do this: [tex]1420*\frac{60}{100} = 852[/tex]
Answer:
852 walk to school
Step-by-step explanation:
i got this because i divided the 1420 into 10 which became a 142, multiply by 6 and you get 852
also you could
it is really simple also, all you have to do is multiply the number of student, S times the precent of students who walk, so s times w, which is 60 precent turend into .6 precent so 1420 x .6

measure 3.5 feet. What is the perimeter
of the table top?
Answer:
i
Step-by-step explanation:
Answer:

Step-by-step explanation:
use the pythagorean theorem to figure out what the hypotenuse is
3.5^2+3.5^2=x^2
12.25+12.25=x^2
25=x^2
x=5
now that you know the hypotenuse, you can find the perimeter by adding up all the sides

To visit his grandmother, Luis takes a train 6.376.376, point, 37 kilometers and a car 5.455.455, point, 45 kilometers.
How many kilometers is Luis's journey in total?
Answer:
Luis traveled 11.82 km in total.
Step-by-step explanation:
The statement should say: To visit his grandmother, Luis takes a train 6.37 kilometers and a car 5.45 kilometers. How many kilometers is Luis's journey in total?
Hence, to find the total distance traveled by Luis we must add the distances of the train (6.37 km) and the car (5.45 km):
[tex] d = d_{t} + d_{c} = 6.37 km + 5.45 km = 11.82 km [/tex]
Therefore, Luis traveled 11.82 km in total.

PLEASE HELP ME WITH THE LITTLE QUESTION
Answer:
y = -x +2
Step-by-step explanation:
First let's find the slope.
(-1,3) and (4,-2)
3 - -2/ -1 - 4 = 5/-5 = -1
Slope = -1
Now let's use slope intercept form:
y1-y2=m(x1-x2)
Let's plug in our slope for m.
y1-y2= -1 (x1-x2)
And now let's substitute y2 and x2 for one of our points, I'll use (4,-2)
y1+2 = -1(x1- 4)
y= -x + 4 -2
y = -x +2
Peter lives in an apartment and pays the following expenses each month: electric bill, $34.80; TV streaming service,
$27.99; and rent, $614.85. Estimate his total expenses for the month by first rounding each value to the nearest tens
place.
Answer:
680
Step-by-step explanation:
add al you can add all of them and then my total came to 67 7.64 rounded to the nearest should be around 680
The total expenses for the month including electric bills, TV streaming service and rent is $677,6.
What is summation?Summation is basically the result obtained by addition of all the numbers whose summation is to be obtained. The symbol used is ∑ for summation.
How to calculate total expenditure?The expenditures done by Peter who lives in an apartment are:
Electric bill=$34.80
TV streaming service=$27.99
Rent=$614,85
Total expenditure incurred by Peter on electric bill, TV streaming service and rent =34.80+27.99+614.85
=$677.64
After rounding off we will get $677.6.
Hence the total expenses done by Peter on electric bill, tv streaming service, rent is $677.6.

In an article in the Journal of Advertising, Weinberger and Spotts compare the use of humor in television ads in the United States and the United Kingdom. They found that a substantially greater percentage of U.K. ads use humor. (a) Suppose that a random sample of 400 television ads in the United Kingdom reveals that 147 of these ads use humor. Find a point estimate of and a 95 percent confidence interval for the proportion of all U.K. television ads that use humor. (Round your answers to 3 decimal places.) (b) Suppose a random sample of 455 television ads in the United States reveals that 119 of these ads use humor. Find a point estimate of and a 95 percent confidence interval for the proportion of all U.S. television ads that use humor. (Round your answers to 3 decimal places.) (c) Do the confidence intervals you computed in parts a and b suggest that a greater percentage of U.K. ads use humor
Answer:
a)
The point estimate is 0.368.
The 95 percent confidence interval for the proportion of all U.K. television ads that use humor is (0.321, 0.415).
b)
The point estimate is 0.262.
The 95 percent confidence interval for the proportion of all U.S. television ads that use humor is (0.222, 0.302).
c)
Yes, because the lower bound of the confidence interval for UK proportions is higher than the upper bound of the confidence interval for US proportions.
Step-by-step explanation:
(a) Suppose that a random sample of 400 television ads in the United Kingdom reveals that 147 of these ads use humor.
In a sample with a number n of people surveyed with a probability of a success of [tex]\pi[/tex], and a confidence level of [tex]1-\alpha[/tex], we have the following confidence interval of proportions.
[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
In which
z is the zscore that has a pvalue of [tex]1 - \frac{\alpha}{2}[/tex].
Sample of 400:
This means that [tex]n = 400[/tex]
Point estimate:
[tex]\pi = \frac{147}{400} = 0.368[/tex]
The point estimate is 0.368.
95% confidence level
So [tex]\alpha = 0.05[/tex], z is the value of Z that has a pvalue of [tex]1 - \frac{0.05}{2} = 0.975[/tex], so [tex]Z = 1.96[/tex].
The lower limit of this interval is:
[tex]\pi - z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.368 - 1.96\sqrt{\frac{0.368*0.632}{400}} = 0.321[/tex]
The upper limit of this interval is:
[tex]\pi + z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.368 + 1.96\sqrt{\frac{0.368*0.632}{400}} = 0.415[/tex]
The 95 percent confidence interval for the proportion of all U.K. television ads that use humor is (0.321, 0.415).
(b) Suppose a random sample of 455 television ads in the United States reveals that 119 of these ads use humor.
Sample of 455:
This means that [tex]n = 455[/tex]
Point estimate:
[tex]\pi = \frac{119}{455} = 0.262[/tex]
The point estimate is 0.262.
95% confidence level
So [tex]\alpha = 0.05[/tex], z is the value of Z that has a pvalue of [tex]1 - \frac{0.05}{2} = 0.975[/tex], so [tex]Z = 1.96[/tex].
The lower limit of this interval is:
[tex]\pi - z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.262 + 1.96\sqrt{\frac{0.262*0.738}{455}} = 0.222[/tex]
The upper limit of this interval is:
[tex]\pi + z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.262 + 1.96\sqrt{\frac{0.262*0.738}{455}} = 0.302[/tex]
The 95 percent confidence interval for the proportion of all U.S. television ads that use humor is (0.222, 0.302).
(c) Do the confidence intervals you computed in parts a and b suggest that a greater percentage of U.K. ads use humor?
Yes, because the lower bound of the confidence interval for UK proportions is higher than the upper bound of the confidence interval for US proportions.

(a) what percentage of the income is spent on salaries.
(b) what is the ratio of the amount for housing to the amount for training,
Answer:
(a) 19%
(b) 5:6

salaries Gh 49,020
training Gh 72,000
housing Gh 60,000
entertainment Gh 12,000

The percentage of the income spent on salaries is 19%.
(b) Ratio of amount for housing to amount for training = [tex]\frac{amount for housing}{amount for training}[/tex]
