Answer and Step-by-step explanation:
Add together the hours, then divide the amount earned by the total amount of hours.
3 + 5 = 8
105 ÷ 8 = $13.125 (which would round up to 13.13) [About $13.13] is earned per hour.

Find the gradient of the line segment between the points (-2,7) and (4,3). Give your answer in its simplest form
Answer:
m = - 2/3 or
m = - 0.66667.
I don't know which form is simpler.
Step-by-step explanation:
All you want is the slope.
The slope formula is
m = (y2 - y1) / (x2 - x1)
y2 = 7
y1 = 3
x2 = - 2
x1 = 4
My choice of which one is 1 and which one is 2 is totally arbitrary. You could have made y2 = 3 and y1 = 7 and x2 = 4 and x1 = -2
m = (7 - 3) / (-2 - 4)
m = 4 / - 6
m = -2/3 or
m = - 0.6667
Alexis bought 6 pounds of hamburger meat for a
barbecue. How many ounces of meat did she buy?
Answer:
96
Step-by-step explanation:
1 pound=16 ounces
6x16=96
Answer:
She bought 96 ounces.
Step-by-step explanation:
When you convert 6 pounds into ounces it's 96 ounces.
1 pound equals 16 ounces.
16 ounces times 6 is 96.
Let X = the number of nonzero digits in a randomly selected 5-digit PIN that has no restriction on the digits. What are the possible values of X? Give three possible outcomes and their associated X values
Answer: there are total 100,000 5-digit PINs.
Three Possible outcomes Associated X values
12345 5
04555 4
00001 1
Step-by-step explanation:
Here, X = the number of nonzero digits in a randomly selected 5-digit PIN that has no restriction on the digits.
Possible number of outcomes = 10 x 10 x 10 x 10 x 10
= 100,000
Possible outcomes Associated X values
12345 5
04555 4
00001 1
Hence, there are total 100,000 5-digit PINs.
Three Possible outcomes Associated X values
12345 5
04555 4
00001 1

An experiment using 35 guinea pigs is set up to study the weight of the pigs after injecting them with a drug. If the population mean is 23.5 grams with a standard deviation of 3.4 grams, what is the margin of error of the sample mean?
I ONLY NEED ONE ANSWER, AND HAS TO BE THE CORRECT ONE!
A. 0.097 grams
B. 0.575 grams
C. 0.701 grams
D. 1.149 grams
E. 1.403 grams
Answer:
Step-by-step explanation:
The margin of error for the sample is roughly 0.255 gm.
What is Standard Deviation?A set of values' variance or dispersion is measured by the standard deviation.
What is a confidence interval?A confidence interval is made up of the mean of your estimate plus and minus the estimate's range.
This is the range of values you expect your estimate to fall within if you repeat the test, within a given level of confidence. Confidence is another name for probability in statistics.
Given,
Standard deviation = 3.4 gm
Population mean = 23.5 gm
Number of pigs = 35
We know, Margin of Error = [tex]\frac{\sqrt{\mu\times\sqrt{\sigma}}}{n}[/tex]
ME = [tex]\frac{\sqrt{23.5\times\sqrt{3.4}}}{35}[/tex].
ME = 0.225 gm.
As a result, the sample mean's margin of error is roughly 0.255 gm.

You roll two six-sided dice numbered from one through six. What is the probability that the sum of the two dice is greater than or equal to six? Round your answer to two decimal places.
Answer:
ok so so here are the numbers equal to 6
1,5
5,1
2,4
4,2
3,3
so five options and there are 36 possible outcomes(6*6)
so 5/36 or 0.14
Hope This Helps!!!
The solution is, the probability that the sum of the two dice is greater than or equal to six is 0.14.
What is probability?Probability can be defined as the ratio of the number of favorable outcomes to the total number of outcomes of an event.
here, we get,
You roll two six-sided dice numbered from one through six.
so here are the numbers equal to 6
1,5
5,1
2,4
4,2
3,3
so five options and there are 36 possible outcomes(6*6)
we get, sample space = 36
favorable outcome = 5
probability = 5/36
so 5/36 or 0.14

Look at the figure. Which point is coplanar with points B, C, and H?
E
G
D
A
==========================================
Explanation:
Points B, C and H are along the right wall as I've highlighted below. The fourth missing point of this wall is point G
The term "coplanar" means that all points are on the same plane. A plane is any flat surface that doesn't bend or curve.

In the figure below, ZAPE and ZEPD are congruent.
What is the arc measure of major arc BAD on circle P in degrees?
Answer:
54degrees
Step-by-step explanation:
From the given diagram;
2<P + 136 + 74 + 42 = 360 (sum of angle at a point is 360degrees)
2<P +252 = 360
2<P = 360 - 252
2<P = 108
<P = 108/2
<P = 54
Hence the measure of <P is 54degrees
Susan rolled a die 888 times.
Which of the following would be a good estimate of the number of times she rolled the number 3 on the die?
A. 248
B. 260
C. 151
D. 103
Answer:
C. 151
Step-by-step explanation:
Since there are 6 sides on a die, and one of them is 3, the chance of rolling a 3 is 1/6.
To estimate how many times Susan rolled a 3, multiply 888 by 1/6:
888(1/6)
= 148
So, Susan rolled 3 on the die around 148 times.
This is closest to answer choice C. 151

The defensive coaches had hoped that the average number of tackles of the opponent’s QB would increase during the game in a distribution of 15% of the tackles in the first quarter,15% in the second,30% in the third, and 40% in the fourth. The mean number of tackles for the 2007 season was as follows: 37, 35, 73, 40. Did the mean sacks per game fit the desired distribution? Let a = 0.10.
5. Mr. Q's class is having a give-
away where his students can
receive 100 classroom credits.
He will pull names out of a hat
and select two winners. Once a
student wins, they are not
eligible to win a second time. If
there are 40 total people in the
class, including you and your
best friend.
What is the probability that both you and your best friend get the 100 classroom
credits? (Show work please)
Answer:
The probability that both me and my best friend get the 100 classroom credits is 0.06%.
Step-by-step explanation:
Since Mr. Q's class is having a give-away where his students can receive 100 classroom credits, and he will pull names out of a hat and select two winners, and once a student wins, they are not eligible to win a second time, if there are 40 total people in the class, including me and my best friend, to determine what is the probability that both me and my best friend get the 100 classroom credits, the following calculation must be performed:
I = 1/40 = 0.025
my best friend = 1/39 = 0.02564
0.02564 x 0.025 = X
0.0006410 = X
X x 100 = 0.064
Therefore, the probability that both me and my best friend get the 100 classroom credits is 0.06%.
Celia simplified the expression Negative 4 x (1 minus 3) minus (2 x + 2). She checked her work by letting x = 5 in both expressions. Her work for the original expression is shown below.
Negative 4 x (1 minus 3) minus (2 x + 2) = negative 4 (5) (1 minus 3) minus (2 (5) + 2) = negative 20 (negative 2) minus 12 = 40 minus 12 = 28.
Celia knows that the simplified expression should also equal 28 when x = 5. Which shows Celia’s simpllifed expression?
Answer:
-4x (1-3) - (2x + 2)
-4(5)(1-3) - (2(5) + 2)
-20(1-3) - (10 + 2)

What is the probability of flipping a coin 10 times and getting tails 6 times? Round your answer to the nearest tenth of a percent. O A. 20.5% B. 11.7% O C. 1.0% O D. 4.4% SUBMIT
Answer:
0.2051
Step-by-step explanation:
The probability of follppping a coin 10 tones and getting a tail 6 times can be solved in different ways :
One way is to use the binomial probability relation :
Where :
P(x = x) = nCx * p^x * q^(n-x)
Number of trials, n = 10
p = 1/2 (probability of obtaining a tail per flip)
q = 1- 1/2 = 1/2
x = 6
P(x = 6) = 10C6 * 0.5^6 * 0.5^4
P(x = 6) = 0.205078125
P(x = 6) = 0.2051
