The high school band director plans to survey his students about the music he should select for their spring concert. Which group would provide the best representative sample?15 girls from all band levels
20 members of the freshman band
22 jazz band members
5 members from each of the 4 grade-level bands

Answers

Answer 1

Answer:

Ans. 5 members from each of the 4 grade-level bands.

Basing on the data provided, all other factions were already categorized to a specific group which will not provide a realistic data. Having representatives per level bands will bridge the gap of unbiased survey analysis.

a sailfish can swim up to 1 mile per hour less than one fifth the top speed of a peregrine falcon. Find the top speed that a sailfish can swim?

Answers

top speed of a peregrine falcon is 240 miles per hour

240 x 1/5 = 48

48-1 = 47

sailfish can swim 47 miles per hour

Answer: The top speed that a sailfish can swim at $((x)/(5)-1)\ mph$

Step-by-step explanation:

Since we have given that

Top speed of a peregrine falcon be 'x'.

One fifth the top speed of a peregrine falcon would be

$(1)/(5)x$

1 mile per hour less than the above is expressed as

$(1)/(5)x-1$

According to question, the top speed that a sailfish can swim would be

$(1)/(5)x-1$

Hence, the top speed that a sailfish can swim at $((x)/(5)-1)\ mph$

A student has to take two quizzes tomorrow. He has only enough time to study for one of them. The history quiz has 5 true or false questions. The science quiz has 3 multiple choice questions.

Answers

Answer:

Answer:

Option B is correct.

Miguel should study for the Science quiz as he will do worse in that quiz by guessing.

Step-by-step explanation:

Miguel has to take two quizzes

1) 4 true or false questions on History with a 0.5 chance of acing the quiz

Expected number of correct questions = np

n = number of questions

p = probability of acing the test

Expected number of correct questions = 4 × 0.5 = 2

2) 3 multiple choice questions on Science with a 0.2 chance of acing the quiz.

Expected number of correct questions = 0.2 × 3 = 0.6

It is evident that guessing would yield a worse result in the Science quiz with less than 1 question expected to be correct than history, where he is still expected to get 2 questions correctly by guessing.

Answer:

He is correct

Solve for y.
y – (–19) = 25
a. –44
b. –6
c. 6
d. 44

Answers

y - (-19) = 25

First, simplify your brackets. / Your problem should look like: $y + 19 = 25$
Second, subtract 19 from both sides. / Your problem should look like: $y = 25 - 19$
Third, subtract 25 - 19 to get 6. / Your problem should look like: $y = 6$

Answer: C) y = 6
