Angelica is a sales representative for appliance. She needs to make at least $5,000 in weekly sales of a particular TV model to

Basile [38]

Answer:

20 TV need to be sold to qualify for the trip.

Step-by-step explanation:

Given: Sale price of each TV is $250

Sales target to qualify for trip is $5000.

As given, T represent TV sold.

Now, finding the number of TV sold to qualify for the trip.

Forming an inequality for the number of TV sold to qualify for trip.

We know, Total amount of TV sold= $Selling\ price\ of\ each\ TV \times Number\ of\ TV\ sold$

∴ To qualify for trip: $250T\geq 5000$

solving it by dividing both side by 250

∴ $T\geq \frac{5000}{250}$

$T\geq 20\ TV$

Hence, Angelica need to sell minimum 20 TV to qualify for the trip.

One of the angles formed by two intersecting lines is 30°. What is the measure of the other three angles?

Helen [10]

Answer:

30° 150° 150°

Step-by-step explanation:

there are multiple ways you could get to this answer. the easiest way is to use linear angles (angles that will add up to 180°). so 180°-30°=150°. then use vertical angles (angles across from each other at an intersection are always equal) and figure out that 30° and 150° are the last two angles

Real estate ads suggest that 56 % of homes for sale have garages, 27 % have swimming pools, and 16 % have both features. a) W

Marizza181 [45]

Answer:

a) 0.4

b) 0.28

c) The events are not independent

d) The events are not mutually exclusive

Step-by-step explanation:

Hi!

Lets call:

Gar = {homes with garage}

Pool = {homes with pool},

A = {homes with pool and garage} = Gar ∩ Pool

The data we are given is:

P(Gar) = 0.56

P(Pool) = 0.27

P(A) = 0.16

a) B = {homes with garage but not pool}. This set B is the set Gar without set A: B = Gar / A

P(B) = P(Gar) - P(A) = 0.4

b) This is a conditional probability:

P(Pool | Gar) = P(Gar ∩ Pool) / P(Gar) = 0.16/0.56 = 0.28

c) To be independent events, it must be, by definition:

P(Gar ∩ Pool) = P(Gar) * P(Pool)

0.16 ≠ 0.56*0.27 = 0.15

Then, the events Gar and Pool are not independent

d) Gar and Pool are not mutually exclusive, because there are houses with both pool and garage. We know that because P(A) is not zero.
