GREYUIT [131]3 years ago

Answer:

$9,840

Step-by-step explanation:

Let the money earned from college be 'x'.

Given:

Total money earned from the two jobs = $50,450

Money earned at the store = 1250 + 4(Money earned at college)

∴ Money earned at the store = 1250 +4x

Now, total money earned by Erica is the sum of money earned at store and college. Therefore,

Total money = Money at store + Money at college

50450=1250+4x+x\\5x+1250=50450\\5x=50450-1250\\5x=49200\\x=\frac{49200}{5}=\$9840

Therefore, the money earned by Erica from her job at the college is $9,840.

A and B are independent events. P(A) = 0.50 P(B) = 0.30 What is P(A/B)? a. not enough information. b. 0.30 c. 0.50 d. 0.15
Gala2k [10]

Answer:

0.50

Step-by-step explanation:

P(A|B)=P(A and B)/P(B) is the formula to find a conditional probability when A and B are not independent.

A and B are independent. This means B has no effect of A. This means P(A|B)=P(A).

P(A|B)=P(A) since A and B are independent

P(A|B)=0.50

Which graph represents the solution to the given system y=-3x-4 and y=3/4x+2
tatyana61 [14]

Answer:

See attached picture

Step-by-step explanation:

To graph, use y=mx+b as a guide where m is the slope and b is the y-intercept.

y=-3x-4

Start at -4 on the y-axis. Plot a point. This is the y-intercept b. From this point count down 3 units and 1 unit to the right. Plot this point and connect.

y=3/4x +2

Start at 2 on the y-axis. Plot a point. This is the y-intercept b. From this point count up 3 units and 4 units to the right. Plot this point and connect.
