Answer:

33

Step-by-step explanation:

(1+x) + (3+x) + (5+x) + (7+x) + (9+x) + (11+x) + (13+x) = 231

7x + 49 = 231

7x = 231 - 49

7x = 182

x = 182/7

x = 26

To find the middle number;

7 + x

= 7+26

= 33

If a customer at a particular grocery store uses coupons, there is a 50% probability that the customer will pay with a debit car
AlexFokin [52]

Answer:

A. 0.52

Step-by-step explanation:

Let D be the event that person used Debit card and C b the event that person used coupon.

We have to find the probability of customer does not use coupons given that a customer does not pay with a debit card,

P(C'/D')=P(C')P(D'/C')/[P(C')P(D'/C')+P(D')P(D'/C')]

We are given that P(D)=0.35, P(C)=0.30 and P(D/C)=0.5.

P(D')=1-0.35=0.65

P(C')=1-0.3=0.7

P(D'/C')=0.5.

P(C'/D')=0.7(0.5)/[0.7(0.5)+0.65(0.5)]

P(C'/D')=0.35/[0.35+0.325]

P(C'/D')=0.35/[0.35+0.325]

P(C'/D')=0.35/0.675

P(C'/D')=0.5185=0.52

Thus, the probability of customer does not use coupons given that a customer does not pay with a debit card is 0.52.

\angle c and \angle e are opposite

\angle c and \angle e are congruent

Hence:

\angle c and \angle e are vertical

<em>(d) is correct</em>
