A = $ 2,736.00
Equation:
A = P(1 + rt)
Calculation:
First, converting R percent to r a decimal
r = R/100 = 2%/100 = 0.02 per year,
then, solving our equation
A = 2400(1 + (0.02 × 7)) = 2736
A = $ 2,736.00
The total amount accrued, principal plus interest,
from simple interest on a principal of $ 2,400.00
at a rate of 2% per year
for 7 years is $ 2,736.00.
15/17 Because there is a 13/13 chance but then you put a ball in from Urn 1 and that is 2/4. Also, 13/13 plus 2/4 = 15/17
We will evaluate each case separately:
with a roller:
P1 = (40/8) * 10 + (1/2) * 10 = 55 $
spray gun:
P2 = (40/20) * (5 + 10) + (1) * (10) = 40 $
Then, the saving is:
P1-P2 = 55-40 = 15 $
answer:
you save by using the spray gun on a paint job that involves painting 40 m2 15 $
Chance of seed growing into healthy plant: 0.65
Chance of seed NOT growing into a healthy plant: 0.35
To answer this question, we will use the nCr button on the calculator.
In this situation, n = 8 and r = 1.
If 1 seed doesn't grow, then 7 seeds will grow. So will raise 0.65 to the 7th power and 0.35 to a power of 1
7 seeds grow, so we use the 7th power
1 seed doesn't grow, so we use power 1 :
So the answer is:
⁸C₁ × (chance of successful growth)⁷ x (chance of Unsuccessful growth)¹
= ⁸C₁ × 0.65⁷ × 0.35¹
= 0.137 (3sf)

Answer:
Probability that exactly one seed doesn't grow is:
0.137
Answer:
A) The box plot will be symmetrical because there are no exceptionally high or low prices.
Step-by-step explanation:
If they were made into a box plot, it would be almost, if not perfectly symmetrical because it is pretty balanced.
