Answer:
soln
A=(9,j)
x1=9,y1=j
B=(10,4)
x2=10,y2=4
slope=1
by using the fomulaof slope,
slope=y2-y1/x2-x1
1 =4-j/10-9
1 = 4-j/1
1=4-j
j=4-1
j=3
Answer:
j = 3
Step-by-step explanation:
(9 , j) ; [tex]x_{1}= 9[/tex] and [tex]y_{1} = j[/tex]
(10, 4) ; [tex]x_{2} = 10[/tex] and [tex]y_{2} = 4\\\\[/tex]
[tex]Slope = \frac{y_{2}-y_{1}}{x_{2}-x_{1}}\\\\ \frac{4 - j}{10-9} = 1\\\\\frac{4 - j}{1}=1[/tex]
4 - j = 1 {Subtract 4 from both sides}
-j = 1 -4
-j = -3 {Multiply both sides by (-1) }
j = 3

No scams. Show your work. write answer as a percent and round the nearest whole number if needed.
Answer:
Step-by-step explanation:
we will find the area of the inner circle and then the area of the outer circle and see what the ratio is between those 2
area of a circle = [tex]\pi[/tex][tex]r^{2}[/tex] (where r is the radius, NOT the diameter, easy to confuse)
the radius of the inner circle is 2.5. which is half of the diameter of 5
inner circle = [tex]\pi[/tex]*(2.5)^2
inner circle = 19.6349...
outer circle = [tex]\pi[/tex]*(10^2)
outer circle = 314.1592...
the ratio is 19.6349... / 314.1592... = 0.0625
0.0625 = 6.25%
= 6% ( rounded to nearest whole number )
Imagine you wish to determine whether the mean number of hours worked per week by men in a sample differs from the national 40-hour average. Use the information below to calculate the t-statisic. Be sure to also specify the degrees of freedom. Weekly Hours Worked by Men Range 60 Minimum value 5 Maximum value 65 Mean 42.31 Standard deviation 10.00 Number of observations 29
Answer:
Step-by-step explanation:
The sample standard deviation (s) divided by the square root of the number of observations in the sample (n).

C and D are mutually exclusive events. Find P(C or D).
P(C)= 3/7= P(D)= 4/7
P(C or D)
Answer:
[tex]P(C\ or\ D) = 1[/tex]
Step-by-step explanation:
Given
[tex]P(C) = \frac{3}{7}[/tex]
[tex]P(D) = \frac{4}{7}[/tex]
Required
[tex]P(C\ or\ D)[/tex]
Since the events are mutually exclusive, then:
[tex]P(C\ or\ D) = P(C) + P(D)[/tex]
So, we have:
[tex]P(C\ or\ D) = \frac{3}{7} + \frac{4}{7}[/tex]
Take LCM
[tex]P(C\ or\ D) = \frac{3+4}{7}[/tex]
[tex]P(C\ or\ D) = \frac{7}{7}[/tex]
[tex]P(C\ or\ D) = 1[/tex]

Deena works at a customer service call center. She fields an average of 5 calls per hour. Employees are encouraged to field more
than 200 calls per week Deena has already fielded 75 calls this week.
How many more hours, x, does Deena need to work this week to reach the weekly goal of fielded calls if she continutes to field an
average of 5 calls per hour? Select the inequality that includes the fewest number of hours Deena can work this week and still
reach the weekly goal.
1. She needs to field 240 calls, but has already done 96. => 240-96=144
2. She fields six calls per hour, and how many hours will it take. This is a hint for division. 144/6=24
3. Therefore, x, where x is the minimum number of hours Deena will need to answer 144 more calls, is at least 144.
4. Answer: c. x>24

A bottle contains 750mL of fruit punch with a concentration of 50% pure fruit juice. Johan
drinks 100mL of the punch and then refills the bottle with an equal amount of a cheaper
brand of punch. If the concentration of juice in the bottle is now reduce to 48%, what was
the concentration in the punch that Johan added?
Answer:
The juice concentration in the punch that Johan added was 35%.
Step-by-step explanation:
Since a bottle contains 750mL of fruit punch with a concentration of 50% pure fruit juice, and Johan drinks 100mL of the punch and then refills the bottle with an equal amount of a cheaper brand of punch, if the concentration of juice in the bottle is now reduced to 48%, to determine what was the concentration in the punch that Johan added, the following calculation must be performed:
750 = 100
650 = X
650 x 100/750 = X
65000/750 = X
86,666 = X
86.666 x 0.5 + 13.333 x 0.4 = 0.486662
86.666 x 0.5 + 13.333 x 0.39 = 0.4853287
86.666 x 0.5 + 13.333 x 0.35 = 0.4799955
Thus, the juice concentration in the punch that Johan added was 35%.

I have the answer for this geometry question just how to I solve it. Quickest and correct and semi-long explanation gets brainliest and 100 points. HURRY PLEASE!!!
Answer:
75
Step-by-step explanation:
If the area of ABCD is equal to 45, then the perimeter of EFG is equal to x * 1.5 = 45. 45 / 1.5 = 30, so the perimeter of EFG is equal to 30. This means that each side is equal to 10.
The height of the equilateral triangle EFG creates two 30-60-90 triangles, each with a hypotenuse of 10 and a short side equal to 5. We know that the long side of the 30-60-90 triangle (here the height of EFG) is equal to √3 times the short side, or 5√3.
We then apply the formula for the area of a triangle, which is 1/2 * b * h. We get 1/2 * 10 * 5√3 = 5 * 5√3 = 25√3.
In general, the height of an equilateral triangle is equal to √3 / 2 times a side of the equilateral triangle. The area of an equilateral triangle is equal to 1/2 * √3s/ 2 * s = √3s2/4.

A sphere has a radius of 2 m. Calculate its surface area. Round to the nearest whole number
a
b.
50 sq.m
113 sq.m
C.
d.
212 sq.m
103 sq.m
Please select the best answer from the choices provided
A
Answer:
50 square meters should be your answer
Step-by-step explanation:
The formula of the Surface Area of a sphere is 4πr2 (4*r*squared)
if the radius of the sphere is 2 m, our formula will become 4π(2)[squared]
let us break this down into two pieces:
4π = 12.5663706144
2[squared] = 4
Then when we multiply our answers:
12.5663706144 * 4 = 50.2654824576
since it says to round it to the nearest whole number, we can round this to 50
