The function C(x)=17.5x−10 represents the cost (in dollars) of buying x tickets to the orchestra with a $10 coupon. a. How much

Natasha_Volkova [10]

Answer:

a. It would cost $77.50 to buy 5 tickets.

C(x)=17.5(5)-10

C(x)=87.50-10

C(x)=77.50

b. You can buy 8 tickets with $130

C(x)=17.5x-10

130=17.5x-10

Add 10 on both sides

140=17.5x

Divide 17.5 on both sides

8=x

A physics class has students. Of these, students are physics majors and students are female. Of the physics majors, are female

11Alexandr11 [23.1K]

Answer:

$P(Female\ or\ Physics) = 0.38$

Step-by-step explanation:

Given

$n = 50$ --- total

$Physics =10$

$Female= 12$

$Both = 3$

Required

$P(Female\ or\ Physics)$

This is calculated as:

$P(Female\ or\ Physics) = P(Female) + P(Physics) - P(Both)$

So, we have:

$P(Female\ or\ Physics) = \frac{Female+ Physics - Both}{n}$

$P(Female\ or\ Physics) = \frac{10+ 12- 3}{50}$

$P(Female\ or\ Physics) = \frac{19}{50}$

$P(Female\ or\ Physics) = 0.38$
