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
If 14 inches of wire cost 42 cents how many inches of wire can be bought with 21 cents
If 14 inches of wire cost 42 cents, with 21 cents can be bought 7 inch of wire
Information about the problem:
Inches bought= 14Inches bought cost = 42 centsAmount = 21 centsInches with 21 cents = ?Calculating how much 1 inch cost, we have:
1 inch cost= Inches bought cost / Inches bought
1 inch cost= 42 cents / 14 inches
1 inch cost= 3 cent/inch
Calculating how much can be bought with 21 cents:
Inches of wire= Amount / 1 inch cost
Inches of wire= 21 cent / 3 cent/inch
Inches of wire= 7 inch

Using the cross-multiplication formula we conclude that 768 cents will be given for 96 can recycled.
What is cross-multiplication?Cross multiplying is the process of multiplying the denominator of the second fraction on the other side of the equals to sign by the numerator of the first fraction on the same side.
In a similar manner, the numerator of the second fraction is multiplied by the denominator of the first fraction. Cross-multiplication is another name for the butterfly method. We employ the cross-multiply approach to identify one or more variables in a fraction. Cross multiplying is another method for comparing fractions.
We will do simple cross-multiplication here
given that for 12 cans we get 96 cents, that is
⇒ 12/96
and for 96 cans we get x cents, that is
⇒ x/96
Now, we do cross-multiplication here
⇒ 12/96 = 96/x
⇒ 12x = 96 × 96
⇒ x = (96 × 96)/12

Help me with number 59 and 60 :)
Answer:
59. a₁ = 4
60. a₁ = 10
Step-by-step explanation:
The general equation for the sum of the first n terms Sₙ of a geometric sequence with common ratio r and first term a₁ is
[tex]S_n = a_1 \dfrac{1-r^n}{1-r}[/tex]
Problem 59
Here we are given
[tex]S_n = \dfrac{31}{4}\\\\r = \dfrac{1}{2}[/tex]
So we can plug these values into the above equation and get [tex]a_1[/tex]
Let's first compute [tex]1 - r^n[/tex]
[tex]1 - r^n = 1 - \left(\dfrac{1}{2}\right)^5\\\\\left(\dfrac{1}{2}\right)^5 = \dfrac{1}{32}\\\\1 - r^n = 1 - \left(\dfrac{1}{2}\right)^5 = 1-\dfrac{1}{32} = \dfrac{32}{32}-\dfrac{1}{32} = \dfrac{31}{32}[/tex]
[tex]1- r = 1 - \dfrac{1}{2} = \dfrac{1}{2}[/tex]
So
[tex]\dfrac{1-r^n}{1-r} = \dfrac{31}{32} \div \dfrac{1}{2} = \dfrac{31}{32} \times \dfrac{2}{1} = \dfrac{31}{16}[/tex]
Substituting this value into [tex]S_n = a_1 \dfrac{1-r^n}{1-r}[/tex] we get
[tex]\dfrac{31}{4} = a_1\dfrac{31}{16}[/tex]
Multiplying both sides by [tex]\dfrac{16}{31}[/tex]
[tex]\dfrac{31}{4} \times\dfrac{16}{31} = a_1\dfrac{31}{16} \times\dfrac{16}{31}\\\\4 = a_1 \textrm{or alternatively }\\ \\\boxed{a_1 = 4}[/tex]
Problem 60
Use the same technique as above
[tex]S_8 = 2550, r = 2\\\\S_8 = a_1 \times \dfrac{1-r^8}{1-r}\\\\\\2550 = a_1 \times \dfrac{1-2^8}{1-2}\\\\2550 = a_1 \times \dfrac{1 - 256}{1-2}\\\\2550 = a_1 \times \dfrac{-255}{-1}\\\\2550 = a_1 \times255\\\\== > a_1 = \dfrac{2550}{255}\\\\\boxed{a_1=10}[/tex]

Step-by-step explanation:
The main courses at a restaurant all contain rice or onion. of the 23 choices, 17 contain onion and 14 contain rice. how many dishes contain both rice and onion?
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
31 - x = 23
x = 31 - 23
x = 8
Hence, the number of dishes that contain both rice and onion is calculated to be 8.

if you have a mixture of 10 lb. sunflower seeds which cost 32c per pound and 16 lb. of cracked corn which cost 18¢per pound, how much would this mixture cost per pound?
By unitary method, we get that the total cost of mixture per pound = 50 cents.
What is unitary method?A single unit's value can be determined from the values of multiple units, and multiple units' values can be determined from the values of single units using the unitary method.
Given:
Cost of 1 pound sunflower seeds = 32 cents.
Cost of 1 pound cracked corn = 18 cents.
Available sunflower seeds = 10lb = 10 pounds
Available cracked corn = 16lb = 16 pounds
To find: Cost of the mixture per pound
Finding:
By unitary method, Cost of 1 pound sunflower seeds = 32 cents.
Cost of 10 pounds sunflower seeds = 32(10) = 320 cents.
Again, by unitary method,
Cost of 1 pound cracked corn = 18 cents.
Cost of 16 pound cracked corn
= 18(16) cents
= 288 cents.
Therefore, total cost of mixture per pound
= 32 + 18 = 50 cents.
