Divide $31.75 by 2 to find out the cost for 1 pack. Then multiply that total times 3 to get the total for 3 packs.

31.75/2 = 15.875

15.875 x 3 = 47.625, rounded to $47.63

motikmotik

Answer:

The correct answer is C) $112.50.

Step-by-step explanation:

The problem requires us to calculate future weekly bill that melinda miller will pay after 3 years if inflation rates is 4%. This can easily be calculated using compound factor formula.

Future value = Present value (1+I%)^n

Future value = 100 (1+4%)^3

Future value = 112.5 dollars

A box contains eighteen $1 bills, ten $5 bills, eight $10 bills, three $20 bills, and one $100 bill. You blindly reach into the

zubka84 [21]

Answer: $7.70

Step-by-step explanation:

Given : A box contains eighteen $1 bills, ten $5 bills, eight $10 bills, three $20 bills, and one $100 bill.

Total bills = $18+10+8+3+1=40$

We know that probability of any event = $\dfrac{\text{Favorable outcomes}}{\text{Total outcomes}}$

i.e. the probability of getting $1 bills = $P(E_1)=\dfrac{18}{40}=0.45$

Probability of getting $10 bills = $P(E_2)=\dfrac{10}{40}=0.25$

Probability of getting $5 bills = $P(E_3)=\dfrac{8}{40}=0.2$

Probability of getting $20 bills = $P(E_4)=\dfrac{3}{40}=0.075$

Probability of getting $100 bills = $P(E_5)=\dfrac{1}{40}=0.025$

$\text{Expected value =}1\times P(E_1)+5\times P(E_2)+10\times P(E_3)+20\times P(E_4)+100\times P(E_5)\\\\=1\times 0.45+5\times 0.25+10\times0.2+20\times 0.075+100\times 0.025\\\\=7.7$

Hence, the expected value of your draw= $7.70

How do i find all the missing angles, a b c d e I HAVE TO TURN IT IN SOON AA

castortr0y [4]

Step-by-step explanation:

for a

a+,38°=90°{ angle at circumference through center is 90°}
a=90-38
a=52°

for e

e=38°{base angle of isosceles triangle r equal}

for d

38°+e+d=180°{sum of angle of triangle}
d=180-76
d=104°

for. c

c+d=180°{straight angle}
c=180-104°
c=76°

for b

a+b+c=180°{sum of angle of triangle}
b=180-128
b=52°

hope it helps.
