Answer:
1 * 10^12
Step-by-step explanation:
Scientific notation is a representation of a large number in a short form. The answer, 1*10^12 (read as ten to the twelfth power) essentially says that the number when expanded is 1 with 12 zeros appended to it. If you did a number like 7 trillion you would have 7 * 10^12.
Same thing can be applied for 1,000,000 (one million).
1 * 10^6 because one million has 6 zeros appended to it.
Mean: Average of the numbers in a set of data.
The mean of a data set is equal to the sum of the set of numbers divided by how many numbers are in the set. If we want to find the mean of the data set shown here, let's begin by adding the numbers.
35 + 40 + 45 + 50 + 55 + 60 + 65 = 350
Now, this will be divided by how many numbers are in the set which is 7.
350 ÷ 7 = 50.
Therefore, the mean of the set of data shown here is 29.2.
Answer:
Step-by-step explanation:
- Use ratios to solve for x. Corresponding sides have same ratio.
Q1
- (x + 5)/30 = (36 - 20)/20
- (x + 5)/30 = 16/20 = 4/5
- 5(x + 5) = 4(30)
- 5x + 25 = 120
- 5x = 95
- x = 19
Q2
- (5x - 2)/(3x + 1) = 39/26
- (5x - 2)/(3x + 1) = 3/2
- 2(5x - 2) = 3(3x + 1)
- 10x - 4 = 9x + 3
- 10x - 9x = 3 + 4
- x = 7
TS = 3x + 1 = 3(7) + 1 = 22
Answer:
800%
Step-by-step explanation:
Let p represent the population
in 1965 → the population becomes 2p
in 1970 → the population becomes 2(2p) = 4p
in 1975 → the population becomes 2(4p) = 8p
p ——————> 100%
8p ————-—-> x%
then
