A company has 200 employees there are 150 female employees. 40 employees are under the age of 20. The probability of randomly selecting an employee who is female or is under the age of 30 is 85%. What is the probability of randomly selecting an employee who is female and under the age of 30?
Answer and explanation:
Probability= number of favorable outcomes/ total number of outcomes
Probability of selecting an employee who is female= number of female employees/ total number of employees
Probability of selecting an employee who is female= 150/200
Probability of selecting an employee who is under 30= number of employees under 20/ total number of employees
Probability of selecting an employee who is under 30 = 40/200
Probability of randomly selecting an employee who is female and under the age of 30= Probability of selecting an employee who is female × Probability of selecting an employee who is under 30
Probability of randomly selecting an employee who is female and under the age of 30= 150/200×40/200=15/20×4/20=3/20= 0.15
Therefore there's a 15% chance of selecting an employee who is female and under the age of 30

Which value from the set
{1/2, 2/3, 4/3,5/2} is a value of x that will make the equation 3/4 + x = 9/8 true?
a.2/3
b.4/3
c.5/2
d.1/2
Answer:
2/3
Step-by-step explanation:
that does not say + it a division sign how to got 2/3
(3/4) / x = (9/8)
To solve this equation, we want x alone so we start by multiplying x on both sides like this:
((3/4) / x)x = (9/8)x
Which equals:
(3/4) = (9/8)x
Then we divide each side by 9/8 to like this:
(3/4) / (9/8) = ((9/8)x) / (9/8)
(3/4) / (9/8) is 2/3 and ((9/8)x) / (9/8) leaves x which means we end up with x = 2/3. Therefore, the answer to "3/4 divided by what equals 9/8?" is as follows:
2/3
It is always good to double-check your math to make sure you did it right. When we entered 2/3 for x in this equation (3/4) / x = (9/8), we get the following true equation which means our math is correct.
(3/4) / (2/3) = (9/8)
The value of x will be 2/3
What is an equation?
Equation: An equation is basically a statement that equates two expressions.
An equation must contain an "equality" sign.
Given,
3/4 + x = 9/8
Let us make it correct . Replace + sign with / to get the required answer.
(3/4) / x = (9/8)
To solve this equation, we want x alone so we start by multiplying x on both sides like this:
((3/4) / x)x = (9/8)x
(3/4) = (9/8)x
Then we divide each side by 9/8 to like this:
(3/4) / (9/8) = ((9/8)x) / (9/8)
(3/4) / (9/8) is 2/3 and ((9/8)x) / (9/8) leaves x which means we end up with x = 2/3.
Therefore, the answer to "3/4 divided by what equals 9/8?" is as follows:2/3

4. Consider the right triangle below.
If the perimeter is 1,013 units, find the value of x and the area of the
triangle.
16x + 27
14x - 45
25x
The value of x is
The area is
square units.
Answer:
16x+27+14x-45+25x=1013 units
X= 18.75
Area= b × h × (1/2)
A= 1/2 × 327 × 217.5 = 35561.25 units^2
Answers:
x = 1031/55 = 18.74545 approximatelyarea = 35,542.92 square units approximately==============================================================
Explanation:
The perimeter is the sum of the exterior sides. We'll add up these three sides
16x+2714x-4525xand set the sum equal to the perimeter 1013
The equation we need to solve is
(16x+27)+(14x-45)+(25x) = 1013
Solving for x leads to...
(16x+27)+(14x-45)+(25x) = 1013
16x+27+14x-45+25x = 1013
(16x+14x+25x)+(27-45) = 1013
55x-18 = 1013
55x = 1013+18
55x = 1031
x = 1031/55
x = 18.74545 approximately
-----------------------------
Use this x value to find the length of each side. I'll use the decimal form of x. We get the following side lengths:
16x+27 = 16*(18.74545) + 27 = 326.927214x - 45 = 14*(18.74545) - 45 = 217.436325x = 25*(18.74545) = 468.63625Those values are approximate.
We can then find the area of the triangle
area = (1/2)*base*height
area = (1/2)*(326.9272)*(217.4363)
area = 35,542.92036868
area = 35,542.92
The area is approximate as well.

one day. Using t to represent the number of trees he planted, which equation can be used to
represent this situation? How many trees did the landscaper plant that day
Answer:
450 divided by 75 = t
he plated 6 trees
Step-by-step explanation:
Answer: 75t = 450 ; 6 trees
Step-by-step explanation:

If the length of the longest side of the rectangle is 20cm find the shaded area to the nearest hundredth
Answer:
Step-by-step explanation:
diameter of each circle = 20/2 = 10 cm
rectangle is 20 cm by 10 cm
area of rectangle = 20×10 = 200 cm²
radius of each circle = 10/2 = 5 cm
area of each circle = πr² = 25π cm²
shaded area = 200 - 2(25π) = 200 - 50π =42.92 cm²

Estimate 0.95% of 700
Answer:
6.65
Step-by-step explanation:
0.95% of 700
= 0.0095*700
= 6.65
The value of 0.95% of the number 700 is 6.65.
The percentage is defined as representing any number with respect to 100. It is denoted by the sign %. The percentage stands for "out of 100." Imagine any measurement or object being divided into 100 equal bits.
Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.
Given that the number 700 is 0.95%. The number will be calculated as below,
Number = 0.95% of 700
Number = 700 x 0.95/100
Number = 6.65
Therefore, the value of 0.95% of the number 700 is 6.65.

Step-by-step explanation:
I don't know how to graph this answer, sorry!
The solution of the inequality 7n - 1 > 76 gives n < 11 along with the graph.
Given Inequality:
7n - 1 > 76
To solve the inequality add 1 on both side of inequality as
7n - 1 + 1 > 76 + 1
7n > 77
Now, divide the inequality by 7 as
7n/ 7 > 77/ 7
n > 11.
