Answer:
P(1 dime then 1 nickel)= 15/208= 0.072115
or 7.2%
Step-by-step explanation:
No coin replenished.
total coins =65
P(1 dime then 1 nickel) = (20/65) * (15/64) =20 * 3 / (13 * 64) = 15/(13*16)
P(1 dime then 1 nickel)= 15/208= 0.072115
or 7.2%
The value of the final deposit is 5000. The value of the one a year previously is 5000*1.1 = 5500. The one previous to that has a value of 5000*1.1^2 = 6050. The first deposit has a value of 5000*1.1^3 = 6655.
The total value of the 4 deposits is
.. 6665 +6050 +5500 +5000 = 23,205
You will have $23,205 just after you make the 4th deposit.
_____
This is the sum of 4 terms of a geometric sequence with common ratio 1.1 and initial value 5000. That can be calculated as
.. a0*(r^n -1)/(r -1)
.. 5000*(1.1^4 -1)/(1.1 -1)
.. = 5000*4.641
.. = 23,205
Answer:
B. Distributive property.
Step-by-step explanation:
The expression is simplified by expanding it using the distributive property which says for any real numbers and
and upon simplification the expression becomes:
Answer:
see below
Step-by-step explanation:
We can see the blue angle is 150° and is made up of 90° and something. That something is 150 - 90 = 60°. Since x and 60° are vertical angles, x = 60°.
Answer: 30
Step-by-step explanation:
180=88+3x+2
180=90+3x
90=3x
x=30
