a. By what percent is the number of females greater than the number of males? Round your answer to the nearest tenth.
35 divided by 65
b. By what percent is the number of males less than the number of females? Round your answer to the nearest tenth.
Answer:
a = 50 b = 50
Step-by-step explanation:
a. 35/65=0.53 - rounded to the nearest tenth would equal to 50.
b.
65-35=30
30/65 = .46

114.6 = 6b
b = 114.6/6
b = 19.1
What is 8/9 divide 4
Answer: 8/9 divided by 4 is 2/9.
Step-by-step explanation: If you want to divide fractions, first you need to find the reciprocal of the second term. The reciprocal is when you swap the numerator and the denominator. The reciprocal of 4 is 1/4. Then, you multiply 8/9 is 1/4. 8 x 1 is 8, and 9 x 4 is 36. The answer is 8/36, which you can simplify into 2/9.
The value of the expression (8/9)÷4 is (8/9)×1/4.
What is PEMDAS rule?PEMDAS rule states the correct order of simplifying an expression is as follows -: Parenthesis, exponents, multiplications, divisions, additions, and, subtractions.
Given, A fraction 8/9 and it is being divided by 4.
∴ (8/9)÷4.
= (8/9)×1/4. (think of flipping the divisor to make it a multiplier)
= 32/9
Or
3 whole 5/9.

The Career Placement department at a university wants to administer a survey to determine student awareness of the resources offered. The department expects that student awareness of the Career Placement resources will vary significantly depending on how many years a student has attended the university, so they plan to randomly select 30 freshmen, 30 sophomore, 30 juniors, and 30 seniors. This type of sample can be best described as a: *
Answer:
This type of sample can be best described as a stratified sample
Step-by-step explanation:
Samples may be classified as:
Convenient: Sample drawn from a conveniently available pool.
Random: Basically, put all the options into a hat and drawn some of them.
Systematic: Every kth element is taken. For example, you want to survey something on the street, you interview every 5th person, for example.
Cluster: Divides population into groups, called clusters, and each element in the cluster is surveyed.
Stratified: Also divides the population into groups. However, then only some elements of the group are surveyed.
In this question:
The students are divided into groups, according to how many years they have attended the university. Then, from each group, some(30) students are surveyed. This is an example of Statrified Sampling

a salmon can swim 37.5 meters in 3 seconds. A swordfish can swim 3,204 meters in 2 minutes. which fish swims faster? explain
Answer:
The salmon can swim faster.
Step-by-step explanation:
The salmon can swim faster BECAUSE, if you multiply 37.5x60 (60 stand for seconds, and 60 seconds is a minute) it equals to 2250. If you do 2250x2, that equals 4500, and the 2 is two minutes. The swordfish swims 3,204 meters in 2 minutes, and the salmon swims 4500 meters in 2 minutes. Therefor, the salmon is faster.

Step-by-step explanation:
Write a recursive formula for the sequence 180,160, 140, 120, 100...
Answer:
g(n) = 180 - 20(n-1)
Step-by-step explanation:
Since your has its g(1) value as 180, we put 180 in front. Then, we subtract 20 multiplied by n-1, n being the sequence number. For example, if the recursive function has recursed 3 times, we do 3-1, which is 2. We multiply 2 with 20, which is 40. Finally, we subtract 40 from 180, which is 140. This equation is equivalent to g(3) = 180 - 20(3-1). When the sequence has g(3), we clearly see the answer is 140. When we look at the sequence, the third number is 140, proving this equation correct.

Mia takes a random sample of 10 of her coworkers and asks them each how many pets they have. Assume that
their results are independent, and let X represent the average number of pets in the sample.
Answer: Each trial isn’t being classified as a success or failure, so X is not a binomial variable.
Step-by-step explanation:
X is not a binomial variable since each trial is not categorized as a success or failure.
What is a binomial variable?The likelihood of failure increased to the power of the difference between the number of successes and the number of tries is multiplied by the chance of succeeding raised to the power of the number of successes.
The chance of success for the trials in question in a binomial distribution must stay constant. Because there are only two possible outcomes when flipping a coin, the likelihood of doing so is 0.5 for each trial.
Since lX indicates the typical number of pets in the sample and their outcomes are independent, X is not a binomial variable.
