Mary has an office-supplies budget of $150 for

tatyana61 [14]

Part a)

The inequality that represents the number of folders f and notebooks n she can purchase is $2.15f+4.60n\leq 150$

Part b)

The graph is attached in figure.

Step-by-step explanation:

Part a)

Total budget of Mary = $150

Price of each folder = $2.15

Price of each notebook= $4.60

Let f represent folder and n represent notebooks the inequality will be:

$2.15f+4.60n\leq 150$

We are using less than or equal to (≤) because the budget is 150. the total price should be less than or equal to 150.

So, inequality that represents the number of folders f and notebooks n she can purchase is $2.15f+4.60n\leq 150$

Part b)

Graph the inequality 2x – 3y = 12

We need to graph the inequality but in the given question the inequality sign is missing.

Considering less than equal to (≤) sign

2x – 3y <= 12

The graph is attached in figure below.

Answer: 90% confidence interval is; ( - 0.0516, 0.3752 )

Step-by-step explanation:

Given the data in the question;

n1 = 72, n2 = 17

P1 = 54 / 72 = 0.75

P2 = 10 / 17 = 0.5882

P_good = 0.75

P_bad = 0.5882

standard ERRROR will be;

SE = √[(0.75×(1-0.75)/72) + (0.5882×(1-0.5882)/17)]

SE = √( 0.002604 + 0.01424)

SE = 0.12978

given confidence interval = 90%

significance level a = (1 - 90/100) = 0.1, |Z( 0.1/2=0.05)| = 1.645 { from standard normal table}

93% CI is;

(0.75 - 0.5882) - 1.645×0.12978 <P_good - P_bad< (0.75 - 0.5882) + 1.645×0.12978

⇒0.1618 - 0.2134 <P_good - P_bad< 0.1618 + 0.2134

⇒ - 0.0516 <P_good - P_bad< 0.3752

Therefore 90% confidence interval is; ( - 0.0516, 0.3752 )
