The probability that a randomly selected senior voted for an eagle mascot is 11/68.
Given that, the Central High School students voted to select a school mascot. The results of the vote are recorded in the table.
We need to find what is the probability that a randomly selected senior voted for an eagle mascot.
What is the formula to find the probability of an event?Probability can be defined as the ratio of the number of favourable outcomes to the total number of outcomes of an event. For an experiment having 'n' number of outcomes, the number of favourable outcomes can be denoted by x. The formula to calculate the probability of an event is as follows.
Probability(Event) = Favorable Outcomes/Total Outcomes = x/n
Now, probability = 55/340 =11/68
Therefore, the probability that a randomly selected senior voted for an eagle mascot is 11/68.

The area of a circle is 23.79cm2.
Find the length of the radius rounded to 2 DP.
Answer:
2.75cm
Step-by-step explanation:
Given data
Area of circle= 23.79cm^2
We know that the formula for the area of a circle is
Area= πr^2
Substitute
23.79=3.142*r^2
23.79/3.142= r^2
7.57=r^2
Square roo both sides
r= √7.57
r= 2.75 cm
Hence the radius is 2.75cm

Which of the following is the most reasonable product of 5 10/11 and 3 16/17
15
18
20
24
Answer:
24
Step-by-step explanation:
Both improper fractions are very close to the next whole number, and since it asks for the most reasonable product (multiply/times) you can round them both up to 6 and 4. 6 x 4= 24
A field has a length of 260 meters and a width of 500 meters. Part of the field, 50 meters by 200 meters, is paved for a parking lot. How much of the area remains unpaved?
Answer: 120,000 meters²
Step-by-step explanation:
First find the area of all the land both paved and unpaved:
= Length * Width
= 260 * 500
= 130,000 meters²
The find the area paved:
= 50 * 200
= 10,000 meters²
The area left unpaved:
= Total area - Paved area
= 130,000 - 10,000
= 120,000 meters²
 A set of measurements is taken and recorded and the table shown.
does the data in the table have a constant rate of change or a constant multiplier, and what is its value?
A.
Constant rate of change of 1.2
B.
Constant multiplier of 1.2
C.
Constant rate of change of 1.5
D.
Constant multiplier of 1.5
Answer;
The correct answer here is constant multiplier of 1.5
Step-by-step explanation:
To get the constant multiplier, we have to take a look at the y values
subsequent y values were obtained by multiplying the preceding y value with a term
So we have it that;
3.6/2.4 = 5.4/3.6 = 8.1/5.4 = 1.5
The correct answer here is constant multiplier of 1.5

some patients participated in a clinical trial for a new drug to treat osteoporosis. A patient is selected at random. The probability that the patient had no change in his bone mass density is 7/13, the probability that he had a slight reduction in his bone mass density is 1/k and the probability that he had a significant reduction in his bone mass density is 1/2k. Find the value of k
Answer:
k = 3.9
Step-by-step explanation:
Since the three possible outcomes are given. Therefore, the sum of all the probabilities of the three possible outcomes will be equal to one:
[tex]\frac{7}{13} +\frac{1}{k}+ \frac{1}{2k} = 1 \\\\\frac{1}{k} \frac{1}{2k} =1-\frac{7}{13}\\\\\frac{3}{2k} \frac{5}{13}\\\\2k = \frac{(13)(3)}{5}\\\\k = \frac{39}{(5)(2)}\\[/tex]
k = 3.9

The price of a snowsuit is reduced by $28.38.
This is a discount of 33%.
a) What is the regular price of the snowsuit?
b) What is the sale price of the snowsuit, including taxes?
Answer:
(a) s = the original price = $28.38 / 0.67 = $42.36
Step-by-step explanation:
Let s represent the original price of the snowsuit.
If $28.38 is a discount of 33% from the original price, then (1.00 - 0.33)s = $28.38, or 0.67s = $28.38.
(a) s = the original price = $28.38 / 0.67 = $42.36
(b) if taxes are 7% then the sale price is (1.07)($42.36) = $45.32.
Of course, if the tax rate is other than 7%, the total sale price will be different.

The zeros of a function are the values of for which the function is equal to zero. Enter a number in each blank to make true statements about the function ()=(2−6)(−4).
Answer:
Here we want to complete the blank to make the equality true:
( ) = (2 - 6)*(-4)
The equality is true if we have the same value in both sides, so we can think of this as an algebraic equation:
x = (2 - 6)*(-4)
We just need to find the value of x.
Then let's solve the right side:
x = (2 - 6)*(-4) = (-4)*(-4)
Remember the rule of signs:
(-)*(-) = (+)
x = (-4)*(-4) = 4*4 = 16
Then we need to complete the blank with the number 16
(16) = (2 - 6)*(-4)

Heck I can't leave I should but I can't---At a local pet store, Shirley noticed that about four out of five customers who bought pets chose goldfish. Shirley wants to know the estimated probability that three randomly selected customers buying pets would not buy goldfish. How could Shirley design a simulation for this scenario?
A.
She could roll a six-sided die three times. On the die, numbers 1 to 3 represent customers who buy goldfish and 4 to 6 represent customers who don’t buy goldfish.
B.
She could spin a spinner divided into nine equal sections three times. On the spinner, four sections represent customers who buy goldfish and five sections represent customers who do not buy goldfish.
C.
She could spin a spinner divided into five equal sections three times. On the spinner, four sections represent customers who buy goldfish and one section represents customers who do not buy goldfish.
D.
She could use a random number generator to generate a set of three numbers from 0 to 9. The numbers 0 to 4 represent customers who buy goldfish, and 5 to 9 represent customers who do not buy goldfish.
E.
She could use a number generator to generate a set of five numbers from 0 to 3. The numbers 0 to 2 represent customers who buy goldfish, and 3 represents customers who do not buy goldfish.
Answer:
C. She could spin a spinner divided into five equal sections three times. On the spinner, four sections represent customers who buy goldfish and one section represents customers who do not buy goldfish.
Step-by-step explanation:
We are told that four out of five customers who bought pets chose goldfish.
Thus;
P(those who bought pets also chose gold fish) = 4/5
Therefore;
P(those who bought pets but do not buy gold fish) = 1 - (4/5) = 1/5
Now, she wants to know the estimated probability that three randomly selected customers buying pets would not buy goldfish.
The probability we have is 1/5.
Therefore,to accommodate the 3 randomly selected customers, we have to multiply the numerator and denominator for each probability by 3.
Thus;
P(those who bought pets also chose gold fish) = 4/5 × 3/3 = 12/15
P(those who bought pets but do not buy gold fish) = 1/5 × 3/3 = 3/15
Looking at the new probabilities, the simulation she can use is to divide a spinner into five equal sections three times so that for each section, we can have the probability of 1/5 and 4/5.
Thus, option C is correct.
Katie has the following grades on the last 5 math tests: 56, 90, 67, 82, 78. What would her average test score be?
Answer:
74.6
Step-by-step explanation:
Tp find the average, add all the scores and divide by the number of scores.
56 + 90 + 67 + 82 + 78 = 373
Now divide 373 by 5.
373 / 5 = 74.6
