Answer: $10,800
Step-by-step explanation:
$1000 * 30% = $300
y = 300x + 1000
12 * 3 = 36
y = 300(36) + $1000
y = $10,800
There will be $10,800 in the account when the three years have passed.
The answer is 8.45498149331, you can round it to the nearest thousandths place though, too.
Answer:
0.3446
Step-by-step explanation:
P(X≥2) = 1 − P(X<2)
P(X≥2) = 1 − P(X=0) − P(X=1)
P(X≥2) = 1 − ₆C₀ (0.2)⁰ (0.8)⁶ − ₆C₁ (0.2)¹ (0.8)⁵
P(X≥2) = 1 − 0.2621 − 0.3932
P(X≥2) = 0.3446
Answer:
Jill bought 16 books and Sam bought 9 books
Step-by-step explanation:
Let the number of books that Jill bought be j.
Let the number of books that Sam bought be s.
Jill bought 7 more books than Sam:
j = 7 + s
They bought 25 books altogether:
j + s = 25
Put j = 7 + s into the second equation:
7 + s + s = 25
7 + 2s = 25
2s = 25 - 7 = 18
s = 18/2 = 9 books
Therefore:
j = 7 + s = 7 + 9
s = 16 books
Jill bought 16 books and Sam bought 9 books.
