Answer:
15 burgers!
Step-by-step explanation:
The trick is to get rid of the decimal point from the number we are dividing by.
How? We can "shift the decimal point" out of the way by multiplying by 10, as many times as we need to.
But we must do the same thing to both numbers in the division.
Example: 15 divided by 0.2
Let us multiply the 0.2 by 10, which shifts the decimal point out of the way:
0.2 × 10 = 2
But we must also do it to the 15:
15 × 10 = 150
So 15 ÷ 0.2 has become 150 ÷ 2 (they are both 10 times larger):
150 ÷ 2 = 75
And so the answer is:
15 ÷ 0.2 = 75
Answer:
There is 16.2% probability that a randomly selected individual will be between 185 and 190 pounds
Step-by-step explanation:
Z score
The z score is used to determine by how many standard deviations the raw score is above or below the mean. It is given by:
z = (x - μ) / σ
where μ is the mean, x = raw score and σ is the standard deviation.
Given μ = 180, σ = 8.
For x = 185:
z = (185 - 180)/8 = 0.625
For x = 190:
z = (190 - 180)/8 = 1.25
P(185 < x < 190) = P(0.625 < z < 1.25) = P(z < 1.25) - P(z < 0.625) = 0.8944 - 0.7324 = 16.2%
There is 16.2% probability that a randomly selected individual will be between 185 and 190 pounds
10000-1200x=200*(1.08)^x
x≈8.02
The answer can be 8 years after
X+31+40=180
x=109°
