What is the value of t? Points D and E are midpoints of the sides of triangle ABC. The perimeter of the triangle is 48 units. 2 3 B 6 8 D 37 А 4t 7t + 6 С
Answers
Answer:
2
Step-by-step explanation:
A midpoint divides a segment in two equal segments
DB = 3t
AB = 6t
BE = 4t
BC = 8t
8t + 6t + 7t + 6 = 48
21t = 42
t = 2
The value of t in the given triangle is 2.
What is Triangle?A triangle is a three-sided polygon that consists of three edges and three vertices.
ABC is a given triangle.
The points D and E are the midpoints of the triangle ABC.
The perimeter of the triangle is 48 units.
We know that a midpoint divides a segment in two equal segments.
The midpoint is the middle point of a line segment.
DB = 3t
AB = 6t
BE = 4t
BC = 8t
From perimeter definition the sum of the sides is the perimeter.
8t + 6t + 7t + 6 = 48
Add the like terms
21t = 42
Divide both sides by 21
t = 2
Hence, the value of t in the given triangle is 2.

A game at the fair involves a wheel with seven sectors. Two of the sectors are red, two of the sectors are purple, two of the sectors are yellow, and one sector is blue.
Landing on the blue sector will give 3 points, landing on a yellow sector will give 1 point, landing on a purple sector will give 0 points, and landing on a red sector will give –1 point.
Let X = the points you have after one spin. Fill out the missing values in the table.
If you take one spin, what is your expected value?
What changes could you make to values assigned to outcomes to make the game fair? Prove that the game would be fair using expected values.
Answers
The expected value based on the probability will be 3/7.
How to calculate the probability?
Landing on the blue sector will give 3 points = 3/7 points
Landing on a yellow sector will give 1 point = 2/7 points
Landing on a purple sector will give 0 points = 0 points
Landing on a red sector will give –1 point. = -2/7 points
The expected value will be:
= 3/7 + 2/7 + 0 - 2/7
= 3/7
The change to the values assigned to outcomes to make the game fair is to make 3.5 points for landing on the blue sector.

Use the function b = 14j + 12 to find the value of b when j = 3.
Answers
Answer:
b=54
Step-by-step explanation:
b=14(3)+12
b=42+12
b=54
Hey there!
b = 14j + 12
TURN the EQUATION
14j + 12 = b
j = 3
NEW EQUATION: 14(3) + 12
14(3) + 12
14(3) = 42
42 + 12 = b
SIMPLIFY ABOVE and you will have your answer of b
42 + 12 = 54
Therefore your answer is: b = 54

4. A drawer contains 21 black socks and 9 white socks. A number generator simulates randomly selecting 10 socks from the drawer. The number generator is used 10 times and the number of black socks in each trial is shown in the plot.
Does this number generator appear to be fair?
WHY OR WHY NOT?
I know the answer is yes it appears to be fair, but please answer WHY. Thank you :)
Answers
There are 21 black socks and 9 white socks. Theoretically, the probability of picking a black sock is 21/(21+9) = 21/30 = 0.70 = 70%
Assuming we select any given sock, and then put it back (or replace it with an identical copy), then we should expect about 0.70*10 = 7 black socks out of the 10 we pick from the drawer. If no replacement is made, then the expected sock count will likely be different.
The dot plot shows the data set is
{5, 5, 6, 6, 7, 7, 7, 8, 8, 8}
The middle-most value is between the first two '7's, so the median is (7+7)/2 = 14/2 = 7. This can be thought of as the average expected number of black socks to get based on this simulation. So that's why I consider it a fair number generator because it matches fairly closely with the theoretical expected number of black socks we should get. Again, this is all based on us replacing each sock after a selection is made.
HURRY! What value of m completed the two-way table?
Answers
=========================================================
Explanation:
We're told that there are 50 people in each grade that are surveyed. So that means 50 eighth graders were surveyed.
Add up the values along the bottom row. Set the sum equal to 50 and solve for m
m+8+29 = 50
m+37 = 50
m = 50-37
m = 13
Then note how 13+8+29 = 50 along the bottom row. Also, for the top row we have 17+15+18 = 50 as well.
Answer:
A - 13

2) 10-4(6-x) + 5x
Answers
Answer:
1) -2x-12
2) 9x-14
Step-by-step explanation:
1). We use distributive property. We have to multiply -2 by x and 6. This means that the expression is -2x-12.
2). We use the distributive property again. We have to multiply -4 by 6 and x. Therefore, the equation will be 10-24+4x+5x. Then, we have to combine like terms. 10-24 is equal to -14 and 4x+5x is equal to 9x. Therefore, it is equal to 9x-14.

Answer:
184 cm^2
Step-by-step explanation:
To find the surface area, find the area of each of the faces and add them up.
Let's start with the base/bottom.
The dimensions are 6 and 10, and it is a rectangle.
Area = 6 x 10 = 60 cm^2
Next, lets do the slanted sides.
The dimensions are 10 and 5, and they are both rectangles.
Area = 10 x 5 = 50 cm^2
Since there are 2 of the slanted sides, multiply 50 by 2.
50 x 2 = 100 cm^2
Then, do the triangles.
The dimensions are 6 (base) and 4 (height)
Area = 6 x 4 / 2
Area = 24 / 2
Since there are 2 triangles, we do not need to divide by 2. We will need to multiply by 2 afterwards, so there's no point in dividing by 2.
24 cm^2
Finally, add up all the areas.
60 + 100 + 24 = 184 cm^2
