Answer:

210 ÷7 = 30

Step-by-step explanation:

We can round the numbers to numbers that make the math easier

I will round 208 to 210

We know 21 divide by 7 is 3

210 ÷7 = 30

This is very close to the actual answer.

208÷7 = 29.71428571........

1. Average Senior High School annual cost of tuition fee for all private schools in Cavite last year was 46,300 a random sample
anygoal [31]

Answer:

Step-by-step explanation:

H0 : μ = 46300

H1 : μ > 46300

α = 0.05

df = n - 1 = 45 - 1 = 44

Critical value for a one tailed t-test(since population standard deviation is not given).

Tcritical = 1.30

The test statistic :(xbar - μ) ÷ (s/sqrt(n))

The test statistic, t= (47800-46300) ÷ (5600√45)

t = 1500

t = 1500 / 834.79871

t = 1.797

The decision region :

Reject H0: if t value > critical value

1. 797 > 1.30

Tvalue > critical value ; We reject H0

Hence, there is sufficient evidence to conclude that cost has increased.

Which System of Inequalities could be used to solve the problem below?
SCORPION-xisa [38]

a+y≤1000 and 25a+12.50y>15000 is the system of inequalities that could be used to solve the problem.

Step-by-step explanation:

Given,

Price of one adult ticket = a = $25

Price of one youth ticket = y = $12.50

Maximum people that can be hold by theater = 1000

Therefore;

The maximum number of people can be 1000 or less than that.

a+y\leq 1000

As they want to revenue to be more than 15,000 therefore,

25a+12.50y>15000

a+y≤1000 and 25a+12.50y>15000 is the system of inequalities that could be used to solve the problem.
