A dance student wants to know the favorite type of dance class for students at The Dance Academy. She surveys each student in her ballet class. In which way could the results of her survey be most improved?

Answers

Answer 1

Answer: Since you have not presented any choices wherein we can determine the best answer, I will go on and share my thoughts on how she could improve the results of her survey.

Since she just surveyed her ballet class, she should opt for surveying on other classes with other genres. This would entail reliability and validity and eliminate bias about the results.

Answer 2

Answer:

Answer:

A) She could sample an equal number of students in each type of dance class.

B) She could sample a proportional number of students in each type of dance class.

C) She could sample one student in each type of dance class.

D) She could sample one teacher from each type of dance class.

Solve x/ x-2 + x+2/ x >2

Answers

$(x)/(x - 2) + (x + 2)/(x) \ \textgreater \ 2$
$(x(x))/(x(x - 2)) + ((x - 2)(x + 2))/(x(x - 2)) \ \textgreater \ 2$
$(x^(2))/(x(x - 2)) + (x^(2) - 4)/(x(x - 2)) \ \textgreater \ 2$
$(x^(2) + x^(2) - 4)/(x(x - 2)) \ \textgreater \ 2$
$(2x^(2) - 4)/(x(x - 2)) \ \textgreater \ 2$

Answer:

first answer:-1.75

second:-15.75

third:-40.25

Step-by-step explanation:i am too lazy srry

Final answer:

The constant of proportionality is 1.75 inches per hour. The change in water level at 9 hours of draining is 15.75 inches, and at 23 hours of draining it is 40.25 inches.

Explanation:

The constant of proportionality represents the rate at which the water level is changing over time. To find the constant of proportionality, we can use the formula: constant of proportionality = change in water level / number of hours. Comparing the data in the table, we can find that when the number of hours is 2, the change in water level is 3.5. Therefore, the constant of proportionality is 3.5 / 2 = 1.75 inches per hour.

Next, to find the change in water level at 9 hours, we can multiply the number of hours by the constant of proportionality: 9 x 1.75 = 15.75 inches. Similarly, for 23 hours, the change in water level is 23 x 1.75 = 40.25 inches.

A bank offers a 3.7% annual interest rate for a retirement savings account. A worker puts $8,000 into the account. How much will be in the account after a year?

Answers

Answer:

$8,296

Step-by-step explanation:

(see attached for reference)

assuming simple interest, the final amount is given by

A = P(1 + rt), where

A = final amount (we are asked to find this)

P = principal amount = given as $8000

r = rate = 3.7% = 0.037

t = time = 1 year

substituting the known values into the formula,

A = P(1 + rt)

= 8,000 [ 1 + (0.037)(1) ]

= $8,296
