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
I hope this helps :)

12. The quotient of x divided by six is eight.
13. 28 is four times the number x
Help!!!! lol
Answer:
12. x = 48
13. x = 7
Step-by-step explanation:
x/6 = 8
x = 8*6
x = 48
28 = 4x
28/4 = x
x = 7
Answer:
12) x/6 = 8
13) 28 = 4x
Find the value of x please will mark brainlyiest
Answer:
D) x = 8
Step-by-step explanation:
The information given states that ABCD is similar to RSTU.
Line BC is similar to Line ST. ST is 2 times larger that BC.
Line AB is similar to Line RS. RS must be 2 times larger than AB as well, so multiply 4 x 2 to get x = 8.
Hope it helps!!!
A cognitive psychologist is interested in whether increasing reading speed reduces comprehension. She has students complete a reading comprehension task before and after a six-week speed-reading course. In the beginning of the study, a randomly selected group of 81 students scored an average of 107 points on the reading comprehension task. Since the sample size is larger than 30, the cognitive psychologist can assume that the sampling distribution of MD is normal. She plans to use a repeated-measures t test. The cognitive psychologist identifies the null and alternative hypothesis as:
Answer:
H0: Ud >= 0
H1: UD < 0
Step-by-step explanation:
We have the sample size = 81
Mean of x = 107
The alpha level was not given for me to help you calculate further.
This researcher wants to know if increasing reading speed brings about a decrease in the comprehension of the reader.
The hypothesis are
Null hypothesis
H0: U >= 0
Alternative hypothesis
H1: U < 0

Max has $300 in a savings account. He plans to withdraw $10 per week for lunch money. Which inequality
represents the number of weeks Max can withdraw money before his account will be less than $170?
Answer:
300-10w<170
subtract 300 from both sides
-10w<-130
divide by -10, because we are dividing a negative number the inequality sign changes
w>13

A right triangle table top has legs that
measure 3.5 feet. What is the perimeter
of the table top?
Answer:
i
Step-by-step explanation:
Answer:
12 feet
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
3.5+3.5+5=12
AKI-OLA publication annual income of 258,ooo
salaries Gh49,020
training Gh72,000
housing Gh60,000
entertainment Gh12,000
exigencies Gh23,020
(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
Step-by-step explanation:
Given: Gh 258,000
salaries Gh 49,020
training Gh 72,000
housing Gh 60,000
entertainment Gh 12,000
exigencies Gh 23,020
(a) Percentage of the income spent on salaries = [tex]\frac{amount of salaries}{total income}[/tex] x 100
= [tex]\frac{49020}{258000}[/tex] x 100
= 0.19 x 100%
= 19%
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]
= [tex]\frac{60000}{72000}[/tex]
= [tex]\frac{5}{6}[/tex]
The ratio of the amount for housing to the amount for training is 5:6
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
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.

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

Which values are the solutions to the inequality below? Check all that apply.
X^2 < 10
Answer:
3
Step-by-step explanation:
if you can't use calculator, you must know that after a number being square root, it MUST be in positive
for the negative answer will be false
so for the rest of the answer you need to try it
3² = 9 < 10 so it's true
4² =16 > 10 so it's false
the only answer is 3
