In physics, work is equal to the product of force and distance, given that the direction of force is the same with the direction of the distance.
W = Fd
The total force is
F = 1,700 N + 500 N = 2,200 N
Now, if the question is the work needed to lift the barbell from the ground, the distance would be 2 m. Hence, the work would be
W = (2,220 N)(2 m) = 4,400 N·m or 4,400 J
Answer:
12.1%
Step-by-step explanation:
Given that:
Mean (μ) = 20.2 grams and standard deviation (σ) = 0.18 grams.
The z score is a score used to determine the number of standard deviations by which the raw score is above or below the mean. A positive z score means that the raw score is above the mean and a negative z score means that the raw score is below the mean. It is given by:
a) For x < 19.99 g:
From the normal distribution table, P(x < 19.99) = P(z < -1.17) = 0.1210 = 12.1%
The probability that a randomly chosen mouse has a mass of less than 19.99 grams is 12.1%
4.4 inches = 11.176 centimeters.
1 inch = 2.54 cm.
So, to get the answer, you have to multiply 4.4 x 2.54, which gets you 11.176 centimeters.
Answer:
410 kilograms
Step-by-step explanation:
The mean is another way to say average.
Add the weights of all the polar bears together
3,280 kilograms total.
Then divide by the total number of bears
3,280 / 8 = 410
96/7 because if it was any negative number the whole answer would be thrown off so that brings it down to 6 and 96/7 when you plug 6 in the number is to low and when you plug 96/7 in it works perfectly so the answer is c
