Step 1: 0.555 = 555⁄1000
Step 2: Simplify 555⁄1000 = 111⁄200
The given standard deviation of a population (σ) = 7.8
sample size (N) = 85
We have to find standard error of the mean.
The formula to find standard error of the mean
= (standard deviation of the distribution) / (square root of sample size)
= (σ) / (√N)
= 7.8 / (√85)
= 7.8 / 9.219544457
= 0.8460
= 0.85 (approximately taken to two decimal places)
We have got the required answer.
The standard error of the mean is 0.85.
Answer:
They have collected 375 cans of food.
Step-by-step explanation:
In conducting a canned-food drive,the goal of the school is to collect a total of 500 cans of food. They have reached 6/8 of their goal. This means that they have collected 6/8 of the total number of cans of food that they intended to collect. The number of cans of food that they have collected would be
6/8 × 500 = 375 cans of food.
The answer is (4). all u have to do is see what makes sense.
Answer:
20
Step-by-step explanation:
Just plug 3 into the equation for x:
6/3 + 2(3)^2
2 + 18
2 + 18 = 20
