Answer:
sum: 45
count: 15
mean: 3
Step-by-step explanation:
sum the number of times students ate fast food
count the amount of students that took the survey
the average amount of times students went out to eat
1 is D, because if you wrote out all the choices as equations, you would get that A is 1/2 n - 3, B is also 1/2 n - 3, C is 1/2 - 3, and D is 1/2(n - 3)
2 is A, because 3 times her age minus 4 is 3x-4, with x as Marcys age
3 is C, because although 11 x 5 is 55, it says that 5 times a number is LESS than 55, so the answer is 10, or C
4 is B because the mode is 92, the mean is 122, and the median is 88, which would mean that mean>mode>median
Answer:
$ 3,396.81
Step-by-step explanation:
The formula uses to calculate the amount of an investment after t years which is compounded is given as:
A = P(1 + r/n)^nt
Where:
A = Amount of Investment after t years
P = Principal = $3,000
r = Interest rate = 2.5 %
t = Number of years of Investment = 5 years
n = Compounding frequency = semi annually = 2
First, convert R percent to r a decimal
r = R/100
r = 2.5%/100
r = 0.025 per year,
Then, solve our equation for A
A = P(1 + r/n)^nt
A = 3,000.00(1 + 0.0125/2)^(2×5)
A = $ 3,396.81
The total Investment from compound interest on an original principal of $3,000.00 at a rate of 2.5% per year compounded 2 times per year over 5 years is $ 3,396.81.
Answer:
0.73
Step-by-step explanation:
Given: Painting classes were offered on 22 out of 30 days in September.
To find: decimal that is equivalent to the fraction of days in September that classes were offered
Solution:
Total number of days in September = 30
Number of days when painting classes were offered = 22
So,
fraction of days in September when classes were offered =
Therefore,
decimal equivalent to the fraction of days in September when classes were offered = 0.73
