A number is divided by 4, and the quotient is added to 3. The result is 24. What is the number? (Please show how you got it)

Answer:

Step-by-step explanation:

(x/4) + 3 = 24

so in this case try and make x the subject or in other words try to leave x on one side of the equation.

(x/4) = 24 - 3

(x/4) = 21

now multiply 21 by 4 using cross multiplication

so x= 84

Answer: The sample mean $(\overline{x}) = 517$

Step-by-step explanation:

The confidence interval is given by :-

Sample mean ± Margin of error

Given : The scores on a standardized test are normally distributed. If a random sample of standardized test scores is taken and the confidence interval is (497,537).

i.e. Sample mean - Margin of error = 497 ..(i)

Sample mean + Margin of error=537 ..(ii)

Adding (1) and (2), we get

2 (Sample mean) = 1034

⇒Sample mean = 517

Hence, the sample mean $(\overline{x}) = 517$

konstantin123 [22]

Answer: In first question, Number of student's ticket(s) = 400

And number of adult's ticket(d) = 100

In second question, The goal of $3050 fell by $710

Step-by-step explanation:

1. Since, Here d represents the number of adult tickets and s represents the number of student tickets.

And, all 500 seats are filled for a performance.

Therefore, s + d = 500 ------(1)

Also, the price of one adult's ticket = $8.50

The price of one student's ticket= $5.50

And, their is a revenue of $3050 by selling the tickets.

Thus, 8.50 d + 5.50 s = 3050 --------(2)

By solving the equation (1) and equation (2),

we get, s = 400, d=100

Thus, Number of student's ticket(s) = 400

And number of adult's ticket(d) = 100

2. According to the question,

s = 2 d ----- (3)

s + d = 360 -----(4)

By solving equation (3) and (4),

We get, s = 240 and d = 120

thus, the total revenue after selling 360 tickets = 8.50 × 120 + 5.50 × 240 = $2340

But, the goal is $3050 ( according to the question)

Thus the total fall = 3050 - 2340 = $710
