Answer:
slope is 9
Step-by-step explanation:
use the formula y=mx+b wherein m is the slope and b is the y-intercept
to solve for m, use formula (y2-y1)/(x2-x1):
[tex]\frac{127-1}{5-(-9)}[/tex] = [tex]\frac{126}{14}[/tex] (you add 5 and 9 together because negative + negative is positive)
126/14 = 9
Which line plot displays a data set with an outlier?
Answer:
The third plot shows the outlier
Step-by-step explanation:
The other plots dots are closer together than the third image. Therefore making the image that has the outlier would be the third image represented
Jenna's class brought in 40 pieces of fruit for a celebration and 32 pieces of fruit were eaten. What percentage of the fruit was NOT eaten?
Answer:
20%
Step-by-step explanation:
40 pieces total
32 pieces eaten
40 - 32 = 8
8 pieces not eaten
Percentage = (part / whole) x 100%
Percentage = (8 / 40) x 100% = 0.2 x 100%
Percentage = 20%

Answer:
G. 118⁰100% right answer
Answer:
G. 118°
Step-by-step explanation:
Imagine a line, parallel to AD, that passes through B to a point x on the line CD.
∠CBX=∠CAD=28 (corresponding angles)
∠EBX=90 (BX║ED, BE║XD)
∠CBE=∠CBX+EBX
∠CBE=28+90

(5, -30) (6, -36)
(-36 + 30)/(6 - 5) = -6/1 = -6

Jeff Bezos, who owns Amazon, has a net worth of approximately $143.1 billion (as of mid-2018). An employee in the Amazon distribution center earns about $13 an hour. The estimated lifespan of the employee is 71 years. If the employee worked 24 hours a day, every day of the year from the moment of his birth, how many lifespans would it take for him to earn wages equivalent to Jeff Bezos' net worth? Round the answer to the nearest whole number.
Answer:
Lifetimes=17,698.39
Step-by-step explanation:
The number of hours, H, in the employee's lifetime is
H=24(365)(71)=621960
At 13/hour, this is lifetime wages of
13(621960)=8,085,480
Divide this into 143,100,000,000 to get
Lifetimes=17,698.39
Note that this does NOT imply that the employee is underpaid.

Simply the expression by combining the like terms:
-6j + 4 + 2j - 1
Answer:
-4j + 3 or 3 - 4j
Step-by-step explanation:
you can combine the terms in any order that you want, but i'm going to begin with the j terms.
first, identify the like terms.
-6j + 4 + 2j - 1
then combine the like terms.
-6j + 2j = -4j
now identify the next set of like terms.
-6j + 4 + 2j - 1
combine those like terms.
4 - 1 = 3
after combining the first set of like terms, you're left with: -4j
after combining the second set of like terms, you're left with: 3
therefore the simplified expression is -4j + 3 or 3 - 4j. rearranging those terms doesn't change the answer, so it doesn't matter what order you write it in.

There are 23 bears in Yellow Park. There are 5 times as many bears in Green Park. Which equation will help us find out how many bears are in Green Park?
A. b=23+5
B. b=23*5
C. b=23/5
D. b=23-5
Answer:
B
Step-by-step explanation:
"5 times as many bears"
A would be 5 more bears than,
B would be 5 times more bears than,
C would be 5 times less bears than, and
D would be 5 less bears than.
Answer:
B. b = 23 * 5
Step-by-step explanation:
Yellow Park: 23 bears
Green Park: 5 times as many bears as in Yellow Park
5 times 23 bears is is 5 * 23 or 23 * 5
Answer: B. b = 23 * 5
A school psychologist notes that the average number of times that students are disruptive during class is 1.4 [μ=1.4] times per day. Following recent classroom policy changes, the psychologist tests if the number of disruptions during class has changed. He records the following number of disruptions observed during a class day: 2, 4, 3, 5, 1, 1, and 4.
A. Test the hypothesis that the number of complaints has increased or decreased using a .05 level of significance.
B. Compute effect size using estimated Cohen's d.
Answer:
Reject the Null ;
0.928
Step-by-step explanation:
Given the data: 2, 4, 3, 5, 1, 1, 4
Sample mean = (2 + 4 + 3 + 5 + 1 + 1 + 4) / 7 = 2.857
Standard deviation, s = 1.57 ( using calculator)
The hypothesis :
H0 : μ = 1.4
H1 : μ ≠ 1.4
Since sample size is small, use T test
Test statistic :
Tstatistic = (x - μ) / s/sqrt(n)
Tstatistic = (2.857 - 1.4) / 1.57/sqrt(7)
Tstatistic = 1.457 / 0.593 = 2.455
Two tailed test at α = 0.05
Tcritical at df = 7-1 = 6 ; α = 0.05 = 2.447
Tstatistic > Tcritical ; reject the null
Since ;
2.455 > 2.447 ; we reject the null ;
There is significam evidence that Number of complaints has changed.
Effect size ;
d = (x - μ) / s
d = (2.857 - 1.4) / 1.57
d = 1.457 / 1.57
d = 0.928

4% of what number is 39
Answer:
975
Step-by-step explanation:
39 ÷ 4% = 975
Answer:
975Step-by-step explanation:
Formula = Number × 100 = 39 × 100
Percent 4
Following shows the steps on how to derive this formula
Step 1 : if 4% of a number is 39, then what is 100% of the number ? Setup the equation.
39 = Y
4% 100 %
Step 2 : Solve for Y
Using cross multiplication of two fractions , we get
4Y = 39 × 100
4Y = 3900 = 975

The Sunny Days Apartment building has a cylindrical, above ground pool in the yard. The radius of the pool is 2 times its height, and the volume is 3000 cubic feet. How deep is the pool? In other words, what is the height of the pool?
9514 1404 393
Answer:
6.2 ft
Step-by-step explanation:
The volume of a cylinder is given by ...
V = πr²h
Here, we have r=2h and V=3000 ft³. Putting these numbers into the formula and solving for h, we get ...
3000 ft³ = π(2h)²h
(3000 ft³)/(4π) = h³ . . . . . divide by the coefficient of h³
h = ∛(750/π) ft ≈ 6.2 ft
The pool is about 6.2 feet deep.

Help on this will mark brainalist!
Answer:
y = 2x - 10
Step-by-step explanation:
Slope-intercept form is...
y = mx + b
To get the slope, you have to use the formula...
(y2 - y1) / (x2 - x1)
In this case,
y2 = 2
y1 = 10
x2 = 6
x1 = 10
So...
(2 - 10) / (6 - 10)
= -8 / -4 = 2
Therefore, slope is 2
y = 2x + b
Using any of the two x and y value provided, input the values in the equation
(I'm going to use 6,2)
2 = 2(6) + b
2 = 12 + b
b = -12 + 2
b = -10
Put this all together...
y = 2x - 10
Hope this helps :)

In the figure, △XYZ ≅ △MNL.
Find m∠Z.
Answer:
m∠Z= 23°
Step-by-step explanation:
if they're equal, as are their angles
124°+33°= 157°
180°-157°= 23°
m∠Z = 23°
The triangles are congruent. Therefore,
ΔXYZ ≅ ΔMNL
∠Y ≅ ∠N
Therefore,
∠Y = 124°
Sum of angles in a triangle = 180°
33 + 124 + m∠Z = 180°
157 + m∠Z = 180°
m∠Z = 180 - 157
m∠Z = 23°
