Answer:
The expected frequency for each category would be:
10.
Step-by-step explanation:
a) Data and Calculations:
Number of respondents = 30
Number of categories = 3
Political preferences (categories) = 3
Probability of each category or preference occurring = 1/3
Expected frequency for each category = 1/3 * 30 = 10
b) The expected frequency for each political category (political affiliation) can be calculated by multiplying the probability of each category (political preferences) by the number of respondents. Note that the expected frequency will be different from the observed frequency, which is the actual number of times that each category of political affiliations will be preferred.
Circumference: C=2pir
C stands for circumference. pi is 3.14... and r is the radius.
of course, you can always do, C=pid. where d is diameter because the radius is half the diameter
Area: A=pir^2
A stands for the Area, pi stands for 3.14... r stands for radius, and the little ^2 is the equation squared. The way to solve that is square the radius and then multiply what you got from squaring the radius by pi.
DO NOT replace radius with the diameter when trying to find the Area
Answer:
Answer 4, the bottom right answer
Step-by-step explanation:
Question was pretty blurry so I had to write it out:
The school Spanish Club is holding a car wash to raise $200 to attend a conference. After spending $10 on supplies, the club will was cars for donations of $4 each.
The situation can be modeled by the inequality 4z-10≥200, which has the solution z≥52.5. What is the best way to interpret this solution?
1. At least 53 members of the Spanish Club must volunteer to help at the car wash.
2. The Spanish Club should have spent at least $52.50 on supplies.
3. The Spanish Club needs $52.50 more to meet its goal.
4. The Spanish Club must wash at least 53 cars to meet its goal.
The answer would be 4, because the inequality is saying 4 dollars times the number of cars minus 10 dollars (for supplies) has to be greater than or equal to their goal of 200 dollars they want to raise.
Another way to explain: The 4z would represent how much money they would make for all the cars they wash, but they have to subtract 10 dollars for the supplies. This total has to be equal to or more than their goal of 200 dollars.
