Steve ran for class president against Mandy. Steve received 5 votes for every 3 votes that Mandy received. Mandy received 420 votes. If all the students only voted once?how many students voted in the election? Pls help ASAP!!
Answer:
1120
Step-by-step explanation:
The ratio Steve : Mandy is 5 : 3.
We use a proportion to find the number of votes Steve received.
x = number of votes Steve received.
5/3 = x/420
3x = 5 * 420
x = 5 * 140
x = 700
Steve received 700 votes.
The total number of votes is the sum of the votes Steve receive and Mandy received.
420 + 700 = 1120
the monthly utility bills in a city are normally distributed, with a mean of $100 and a standard deviation of $12. Find the probability that a randomly selected bill is between $90 to $120
Answer:
0.7493 or 74.93%
Step-by-step explanation:
We are given;
Population mean; μ = 100
Population standard deviation; σ = 12
Sample mean 1; x1¯ = 90
Sample mean 2; x2¯ = 120
Z-score formula of the data given is;
z = (x¯ - μ)/σ
z1 = (90 - 100)/12
z1 = -0.83
z2 = (120 - 100)/12
z2 = 1.67
Since we wan to Find the probability that a randomly selected bill is between $90 to $120.
Thus;
P(90 < x¯ < 120) = P(−0.83 < Z < 1.67)
Probability will be gotten from online probability with 2 z-scores calculator to get;
P = 0.7493

A beach lifeguard wants to create the largest triangular area he can with three lengths of rope to provide beach goers with the maximum amount of space to play and swim in the water. Multiple buoys are attached to each rope in order to identify the designated swimming area. The first rope is 42 feet long, the second is 50 feet long, and the third is 107 feet long. The lifeguard can only cut one of the ropes in order to create a triangle with the largest possible perimeter. How much rope, in feet, will be remaining after the lifeguard creates the designated swimming triangle? (Note: Answer should be a whole number.)
Answer: the answer is 16
Step-by-step- explanation:
Since the two sides of a triangle must be greater than the third we can take the sum of two smallest sides and add them together to equal 92. Meaning the length of the longest side MUST BE 91 feet so the amount of the remaining rope would equal to 107-91 and that’s where we get 16

Jon loves to go bird watching at a nearby animal sanctuary. Find the mean of the following numbers of birds he spotted at the sanctuary in the last few days.
14,10,17,11,9,15,6,14
Answer:
Mean = 12
Step-by-step explanation:
The arithmetic mean of a distribution is the sum of the number of samples in the distribution divided by the number of samples in the dataset. It is a measure of central tendency. The mean is represented as follows:
[tex]\bar x = \frac{\sum x}{n} \\where\\\bar x = mean\\\sum x = sum\ of\ individual\ terms\\n = number\ of\ terms\\\therefore \bar x = \frac{14\ +\ 10\ +\ 17\ +\ 11\ +\ 9\ +\ 15\ +\ 6\ +\ 14}{8}\\\bar x = \frac{96}{8} \\\bar x = 12[/tex]
Mean = 12

What is the measure of CAD
Answer:
CAD = 128
Step-by-step explanation:
The price of a train ticket consists of an initial fee of $5 plus a fee of $2.75per stop
The inequality that represents this scenario is:
[tex]5 + 2.75x \le 21[/tex]
The complete question describes the use of word problems to represent inequalities. The $21 means that there is a limit to the number of stops she can take using the train.
From the complete question, we have the following parameters:
Initial Fee = $5
Rate per stop = $2.75
Amount = $21
The inequality that represents the scenario is calculated using:
Initial Fee + Rate * Number of stops <= Amount
We use <= because the total charges must not exceed the amount.
Let the number of stops be x.
The above formula becomes
[tex]5 + 2.75 * x \le 21[/tex]
[tex]5 + 2.75x \le 21[/tex]
Hence, the inequality that represents this scenario is:
[tex]5 + 2.75x \le 21[/tex]
