a₁₂ = 25 + 11(-2.2)
a₁₂ = 0.8
2.0 a₂ = 57.5 and a₅ = 80, a₈ = ?a₂ = a + d
57.5 = a + d -- (1)
a₅ = a + 4d
80 = a + 4d --- (2)
solve (1) and (2)
d = 7.5
a = 50
a₈ = a + 7d
a₈ = 50 + 7(7.5)
a₈ = 102.5
3.0 a₁₀ = 141 and a₁₃ = 186, a₈ = ?a₁₀ = a + 9d

-49 = a + 21d ---- (1)
a₂₅ = a + 24d
-58 = a + 24d --- (2)
subtract (1) from (2)
d = -3
a = 14
a₁₂ = a + 11d
a₁₂ = 14 + 11(-3)
a₁₂ = -19
5.0 a₄ = -2 and a₈ = 46, a₁₂ = ?a₄ = a + 3d
-2 = a + 3d --- (1)
a₈ = a + 7d
46 = a + 7d ---- (2)
Subtract (1) from (2)
d = 12
a = -38
a₁₂ = a + 11d
a₁₂ = -38 + 11(12)
a₁₂ = 94
6.0 a₉ = 64 and a₁₂ = 88, a₆ = ?a₉ = a + 8d

a₆ = 0 + 5(8)
a₆ = 40

-13 = a + 22d --- (2)
Subtract (1) from (2)
d = -3
a = 53
a₃₆ = a + 35d
a₃₆ = 53 + 35(-3)

Answers
The correct interpretation of the probability P(X < 5) is; 0.8
How to Solve Probability?We are given the probability of the spin values are;
Probability of Spin Value of 0 = 0.4
Probability of Spin Value of 1 = 0.2
Probability of Spin Value of 2 = 0.2
Probability of Spin Value of 5 = 0.1

Find the value of x.

x
Answers
Answer:
140
Step-by-step explanation:
Angles in a triangle add up 180 :
180 = 107 + 33 + y
y = 180 - (107+33)
y = 180 - 140
y = 40
Angles on a straight line add up to 180 so :
180 = x + y
180 = x + 40
x= 180 - 40
x = 140
Hope this helped and have a good day
Answer:
x = 140°
Step-by-step explanation:
Concepts
The Exterior Angle Theorem states that the two remote angles in a triangle is equal to the exterior angle.
Application
In this case, the two remotes angles are 107 and 33°, and the exterior angle is x. Now, all we have to do is just add 107 and 33 to get our answer.

Two lines are intersecting. What is the value of x?
Answers
Answer:
The correct answer is x = 51.
Step-by-step explanation:
We have been given an image of two intersecting lines. We are asked to find the value of x.
We can see that both angles are supplementary (adding up to 180 degrees), so we can set an equation as:
x + 23 + 2x + 4 = 180
x + 2x + 4 + 23 = 180
3x + 27 = 180
3x + 27 - 27 + 180 - 27
3x = 153
3x/3 = 153/3
x = 51
Therefore, the value of x is 51.
Hope this helps:) Goodluck!

Step-by-step explanation:

Given that the line y=ax+b passes through the points A(0; 3) and B(-2;7), how do I find the values of a and b?

To compute the slope, you simply have to find the difference of y coordinates and divide them by the difference of x coordinates:
a = (y2-y1)/(x2-x1)
a = (7-3)/(-2–0)

a = -2
To compute the y intercept denoted by b, we substitute the value of a with -2 in the formula and choose any point (x,y) and substitute their values in the formula as well. Like so:

The load requirement in your plan is 60 psf at a joist spacing of 16 inches . If the room dimensions are length 13 feet 2 inches and width 11feet 7 inches are 2 by 10 boards appropriate
Answers
The correct answer is; No, because the 2 x 10 boards can support neither the width nor length of the room.
How to find the dimensions?
We are given;
Load requirement = 60 psf
Joist Spacing = 16 inches
Length of room; 13 feet 2 inches
Width of room; 11 feet 7 inches.
Since we want to consider whether 2 by 10 boards are appropriate, this length of 2 by 10 will not be appropriate because it cannot cover up for a room with dimensions of 13 feet 2 inches and 11 feet 7 inches.
Thus, we can conclude that No, because the 2 x 10 boards can support neither the width nor length of the room.
The missing options are;
A. Yes, because 2 x 10 boards can support the width and length of the room
B. Yes, because 2 x 10 boards support the 70 psf
C. No, because 2 x 10 boards can support only the width of the room

Given :
⇒ Length = 6 inches
⇒ Width = 1.5 inches
⇒ Height = 1.5 inches

i) Calculate the number of people like black coffee?
ii) How many people don’t like any of the drinks?
Answers
Answer:
32
Step-by-step explanation:
Answer:
i) 52
ii) 66
Step-by-step explanation:
This sort of problem is usually solved using some sort of table or Venn diagram. We have used a table in the attachment such that each of the cells in the grid represents one of the 8 possible combinations of coffee, tea, or chocolate.
The numbers in black are given directly by the problem statement. The numbers in blue are calculated from the numbers in black and one of the other given numbers in the problem statement. The numbers in red are calculated so the totals work out correctly.
The cells shaded blue-gray are "one and only one" of the drinks. The cell shaded purple-gray is "don't like any".
__
i) black coffeeWe assume that any form of "coffee" is "black coffee." The problem statement tells us 52 people like coffee.
__
ii) noneThe last number we calculated is the number who like none of the drinks: 66. This brings the total of non-coffee drinkers to 148.
_____
Additional comment
As noted above, the colors more or less indicate the order of the calculations. We started with 36 who like coffee only, and 46 who like coffee and not tea. That means 46-36=10 like coffee and chocolate, but not tea.
Since 16 like coffee and chocolate, that leaves 16-10=6 who like coffee and tea and chocolate (all three).
96 like chocolate, but 16 of those like chocolate and tea. The other 80 like chocolate, but not tea.
46+16=52, so there must be 0 who like coffee and tea, but not chocolate.
The number who like only one is 108. We already have 36 that are coffee only, 80-10 = 70 that are chocolate only, so there must be 108 -70 -36 = 2 who like tea only.
Now, we can finish filling the top row of the table and the totals in the bottom row.
