"Ten subtracted from the quotient of a number and 5 is 18."

Anika [276]

Answer: n/5 - 10 = 18: this would be the equation. Your answer would be 140.

Step-by-step explanation: Let consider the number as ‘X’

Quotient of a number and 5 can be written as

X divided by 5

Ten subtracted from the quotient of a number and 5 can be written as

(X divided by 5)-10

Ten subtracted from the quotient of a number and 5 is 18 can be written as

(X divided by 5)-10=18

By solving the above equation, find ‘X’

(X divided by 5) = 18 + 10

X/5=28

X = 28 x 5 = 140

Answer:

The sample size is $n =33$

Step-by-step explanation:

From the question we are told that

The margin of error is E = 1.5 seconds

The standard deviation is s = 4 seconds

Given that the confidence level is 97% then the level of significance is mathematically represented as

$\alpha =( 100 -97)\%$

=> $\alpha = 0.03$

Generally from the normal distribution table the critical value of $\frac{\alpha }{2}$ is

$Z_{\frac{\alpha }{2} } = 2.17$

Generally the sample size is mathematically represented as

$n =[ \frac{Z_{\frac{\sigma }{2 } } * \sigma }{E} ]^2$

=> $n =[ \frac{2.17 * 4 }{1.5} ]^2$

=> $n =33$
