In a certain federal prison, it is known that 2/3 of the inmates are under 25 years of age. It is also known that 3/5 of the inmates are male and that 5/8 of the inmates are female or 25 years of age or older. What is the probability that a prisoner selected at random from this prison is female and at least 25 years old?
The probability that a prisoner selected at random from this prison is female and at least 25 years old is 1/64
What is the probability?Probability refers to a possibility that deals with the occurrence of random events.
The probability of all the events occurring need to be 1.
The formula of probability is defined as the ratio of a number of favorable outcomes to the total number of outcomes.
GIven that 2/3 of the inmates are under 25 years of age also, that 3/5 of the inmates are male and that 5/8 of the inmates are female or 25 years of age or older.
The number of mother inmates = 75% (100) = 75
The number of inmates, who are not mothers = 100 - 75 = 25
Selecting an inmate who is not a mother = 1/4
Selecting 3 female who are not mothers = 1/64
Therefore, the probability that a prisoner selected at random from this prison is female and at least 25 years old is 1/64

The perimeter of the rectangle below is 166 units. Find the value of y.
4y + 2
Sy
The value of y is 9.
Perimeter is the total length of the boundary of any closed shape. It is basically the sum of all the sides of a given figure.
Perimeter of a rectangle is given by [ 2( l + b ) ] or (2 l + 2 b ) or
( l + l + b + b), here l and b represent the length and breadth of the given rectangle.
Perimeter of the given rectangle = 166 units ( given )
Length of the given rectangle = 5y ( given )
Breadth of the given rectangle = (4y + 2) ( given )
By putting values in the formula, we get
perimeter = 2 ( l + b )
166 = 2 [ (5y) + (4y + 2) ]
166 = 2 [ 5y + 4y + 2 ]
166 = 2 [ 9y + 2 ]
166 = 2*9y + 2*2
166 = 18y + 4
166-4 = 18y ( moving 4 to other side thus changing the sign to negative )
162 = 18y
162/18 = y ( moving 18 to other side for further solution )
y = 9
Therefore, the value of y for which the perimeter of the given rectangle is 166 units is 9.

The value of y is 9.
The whole length of any closed shape's boundary is known as its perimeter. In essence, it is the total of a given figure's sides.
A rectangle's perimeter can be calculated using [2(l + b)] or (2 l + 2 b) or
(l + l + b + b), where l and b stand for the provided rectangle's length and width
The rectangle's perimeter is 166 units ( given )
The rectangle's length is 5y ( given )
Given rectangle's width equals (4y + 2) ( given )
When we enter values into the formula, we obtain
perimeter = 2 ( l + b )
166 = 2 [ (5y) + (4y + 2) ]
166 = 2 [ 5y + 4y + 2 ]
166 = 2 [ 9y + 2 ]
166 = 2*9y + 2*2
166 = 18y + 4
166-4 = 18y ( moving 4 to other side thus changing the sign to negative )
162 = 18y

Identify the angle relationship and find the measure of the indicated angle.
(Alternate Interior, Alternate Exterior, Corresponding, Same-side Interior)
The angled relationship is the Same-side interior angle where x is 6 and ∠EFG is 102°
For the parallel lines ED and FG, where EF is the transversal,
The angle DEF and the angle EFG are same-side interior angles.
By the same-side interior angle theorem, we can say that the interior angles on the same side of the transversal are supplementary (the sum of the angles is 180°).
∠DEF = 13x°
∠EFG = 17x°
∠DEF + ∠EFG = 180°
13x + 17x = 180
30x = 180
x = 6
∠DEF = 13x = 13*6 = 78°
∠EFG = 17x = 17*6 = 102°
Therefore, the angles follow the same-side interior angles relationship, x = 6 and ∠EFG = 102°

Step-by-step explanation:
-3(b-7) distribute the -3 to the rest of the equation
= -3b + 21
Answer:
Step-by-step explanation:
So we have our equation -3(b-7)
We are multiplying -3 by b, and by 7, and subtracting the products from each other
so, -3x7=-21
and we would have -3b
so now, we can put this back into the equation as
-3b+21 (because the rule is that subtracting a negative from a negative is the same as adding a positive)

options:
2 - 160
4 - 320
6 - 480 . (white bread)
Rye bread is 0 to 500 .
The bread that has the greatest ratio of Calories to slices is the Wheat bread
How to determine the bread that has the greatest ratio of Calories to slices?The table of values is given as
Wheat bread
Slice - Calories
2 - 160
4 - 320

The missing graph that represents the graph of rye bread is added as an attachment
On the graph, we have the following table of values
Rye bread
Slice - Calories
2 - 130
4 - 260
6 - 390
We start by calculating the rates of each table using
Rate = Calories/Slice
So, we have
Wheat bread = 160/2
Wheat bread = 80
Rye bread = 130/2
Rye bread = 65
80 is greater than 65
Hence, the bread that has the greatest ratio of Calories to slices is the Wheat bread

For the two similar triangles, the length of side DA = 4 units.
What is defined as the similar triangles?If two triangles get the same ratio of corresponding sides and then an equal pair of corresponding angles, they are similar.When two or more figures share a common shape but differ in size, they are referred to as similar figures.The three-sided polygon is the triangle. The following is the condition for triangle similarity:Both triangles' corresponding angles are equal, andBoth triangles' corresponding sides are proportional to one another.For the two triangles;
ΔABC ≡ ΔADE

If α =i+j−2k, β =−i+2j+3k andγ =5i+8k, then find c and d such that γ−cα−dβ is perpendicular to both α and β
If [tex]\hat\gamma-c\hat\alpha-d\hat\beta[/tex] is perpendicular to both [tex]\hat\alpha[/tex] and [tex]\hat\beta[/tex], then their dot products are zero.
Recall that for any vector [tex]\hat x[/tex], [tex]\hat x\cdot \hat x = \|\hat x\|^2[/tex].
Now, we have
[tex](\hat\gamma - c\hat\alpha - d\hat\beta) \cdot \hat\alpha = (\hat\gamma\cdot\hat\alpha) - c\|\hat\alpha\|^2 - d (\hat\beta\cdot\hat\alpha) = 0[/tex]

[tex]\hat\beta\cdot\hat\alpha = -1 + 2 - 6 = -5[/tex]

and

Solve for [tex]c[/tex] and [tex]d[/tex]. By elimination,
[tex]5(6c - 5d) - 6(5c - 14d) = 5(-11) - 6(-19)[/tex]

x = 9 / 2. How to find the variable x in the equation?The equation is represented as follows;
2 / 5 (2 - x) = - 1 / 3 x + 1 / 2
open the bracket on the left side
2 / 5 (2 - x) = - 1 / 3 x + 1 / 2
4 / 5 - 2x / 5 = - 1 / 3 x + 1 / 2
Add 1 /3 x to both sides
4 / 5 - 2x / 5 = - 1 / 3 x + 1 / 2
4 / 5 - 2x / 5 + 1 / 3 x = - 1 / 3 x + 1 / 3 x + 1 / 2
4 / 5 + 1 / 3 x - 2 / 5 x = 1 / 2
4 / 5 + 5x - 6x / 15 = 1 / 2
4 / 5 - x / 15 = 1 / 2
subtract 4 / 5 from both sides
4 / 5 - 4 / 5 - x / 15 = 1 / 2 - 4 / 5
- x / 15 = 5 - 8 / 10
- x / 15 = - 3 / 10
cross multiply
- x / 15 = - 3 / 10
-10x = - 45
divide both sides by -10
x = 45 /10
x = 9 / 2
Therefore, the algebraic solution for the variable x is 9 / 2.

The length of a rectangel is 11 less than 9 times the width. The perimeter of the rectangle is 18 inches
According to the question, the given parameters has relationship between the length and the width of the rectangle.
The perimeter of the rectangle is 18 inches.
Now, using standard perimeter as well as area formulas of a rectangle. Therefore, the equation can become:
Let us assume, the width of the rectangle be 'w' inches
The length of a rectangle be (9w - 11)
As we know, perimeter of a rectangle is 2(l + w)
Substitute the calculated parameters in the perimeter formula:
18 = 2(9w - 11 + w)
⇒ 9 + 11 =10w
⇒ w = 2 inches and l = 7 inches
Then, the calculated width is 2 inches and length is 7 inches.
