a fitness club with 100 members offers one free training session per member in either running, swimming, or weightlifting. Thirty of the fitness center members sign up for a free session. The running and swimming sessions are each twice as popular as the weightlifting session. What is the probability that a randomly chosen fitness club member signs up for a free running session?
The probability that a randomly chosen fitness club member signs up for a free running session is 0.4.
Let total s members sign up for the weightlifting session.
So, the total members for the running session is 2x.
And the total members for the swimming session be 2x.
Also here it is given that, thirty of the fitness center members sign up for a free session.
⇒ x + 2x + 2x = 30
⇒ 5x = 30
⇒ x = 30/5
⇒ x = 6
Thereofre, the probability that a randomly chosen fitness club member signs up for a free running session
= total number of members in running session/ number of members sign up for a free session
= 12/30
= 0.4
Hence, the probability that a randomly chosen fitness club member signs up for a free running session is 0.4.

Answer: XYW = 32, WYZ = 85
Step-by-step explanation:
We are looking for what x is, which we can find with the formula:
117 = (6x+44) + (-10x+65)
117 = -4x + 109
8 = -4x
x = -2
We can verify this is correct by plugging it in and seeing if they add up to 117.
6x + 44 (XYW)
= 6(-2) + 44
= -12 + 44
= 32
-10x + 65 (WYZ)
= -10(-2) + 65
= 20 + 65
= 85
32 + 85 = 117
Draw a line representing the "rise" and a line representing the "run" of the line. State the slope of the line in simplest form.
The slope of the line in simplest form is: 1.
How to Find the Slope of a Line?The slope (m) of a line is calculated as:
Slope (m) = rise/run = change in y / change in x.
The horizontal distance across the line is the run, while the vertical distance is the rise.
The blue line shows the rise of the line = 2 units
The red line shows the run of the line = 2 units
Slope (m) = rise/run = 2 units/2 units
Slope (m) = 1
Therefore, the slope of the line in simplest form is: 1.

in infant's Tylenol, 5 ml contains 160 mg of Acetaminophen. If you child's pediatrician says that your child can take 48 mg of Acetaminophen, how many milliliters (ml) should you give the child?
The amount of milliliters (ml) you should give the child is 1.5 ml
How to determine how many milliliters (ml) you should give the child?The given parameters are:
infant's Tylenol, 5 ml = 160 mg
This can be represented as
5 ml = 160 mg
Let the number of ml to give a child that requires 48 mg be x
So, we have:
5 ml = 160 mg
x = 48 mg
Cross multiply
x * 160 = 48 * 5 ml
Divide both sides by 160
x = 1.5 ml
Hence, the amount of milliliters (ml) you should give the child is 1.5 ml

If the main courses at a restaurant all contain rice or onion and of the 23 choices, 17 contain onion and 14 contain rice, then the number of dishes containing both rice and onion will be equal to 8.
The number of dishes that contain both rice and onion at the restaurant can be calculated by using an algebraic expression.
An algebraic expression can be defined as an equation in which both numerals and letters are present.
An algebraic expression for this problem can be given as,
(14 - x) + x + (17 - x) = 23
Here x is equal to the number of dishes containing both rice and onion.
14 + 17 - x + x - x = 23

The correct symbol will be (equal to) 6.5 = 6.5
Use the greater than and less than symbols to compare values and expressions. > is the symbol for more than. 6.5 is commonly thought to mean 6.5 "6.5 is the same as 6.5. " "= "is the sign of equality. Two more comparison expressions are "greater than" and "equal to" (less than or equal to).
Two values are equal when the "equals" sign is used to indicate this. (=)
When two values are obviously not equal, the "not equal to" signal is used. (≠)
To show that one value is smaller than another, we use the "less than" sign. (<)
To show that one value is greater than another, we use the "greater than" symbol. (>)
The answer to the left-hand question is 6.5, whereas the answer to the right is 6.5 * 1 is equal to 6.5.
