Answer:

Step-by-step explanation:

350=12(x+20)

(divide both sides by 12)

29.1667=x+20

(subtract 20 from both sides)

x=9.16667

X (9.17) is the additional amount of money the student must save each month in order to reach his goal.

Find the length of base PQ in the trapezoid.

iris [78.8K]

Answer:

PQ = 20

Step-by-step explanation:

Theorem: The length of the median of a trapezoid is the average of the base lengths.

$\frac{PQ + 12}{2} = 16$

PQ + 12 = 32

PQ = 20

See how easy that is if you know the theorem!

Edna decided to purchase a $15,000 MSRP vehicle at a 5% interest rate for 3 years. The dealership offered her a $1500 cash-back

Ad libitum [116K]

P = A/D, Where P = Monthly payments, A = Total amount owed = 15,000-1,500 = $13,500,

$D= \frac{( 1+ \frac{r}{12} )^{nt} -1}{ \frac{r}{12} (1+ \frac{r}{12}) ^{nt} }$

r = 5% = 0.05, nt = 12*3 = 36

Therefore,
D = $\frac{(1+ 0.05/12)^{36}-1 }{(0.05/12)(1+0.05/12)^{36} }$ = 33.37

Then,

P = 13,500/44.37 = $404.61
The correct answer is c.

A small company plans to invest in a new advertising campaign.

There is a 20% chance that the company will lose $5,000 ,

50% chance of a break even, and a 30% chance of a $10,000 profit

So the expected value from the advertisement campaign is calculated as - 20% of 5000 + 0% of 5000 + 30% of 10,000

= -1000 + 0 + 3000

= 2000

The expected value from the advertisement campaign is $2000.

So the Company must go ahead with the campaign.

Answer : Option A

Hope it helps.

Thank you ..!!
