Answer: Since the dependent variable is the height in cm, and the independent variable is the color of light, then a testable question could be "Will the color of a lamp affect the height of plants?"
Given
MINING A mine produces 42.5 tons of coal per hour.
Find out the how much coal will the mine produce in 9.5 hours.
To proof
As given in the question
A mine produces 42.5 tons of coal per hour i.e in the 1 hour mine produces the 42.5 tons .
Let us assume that the coal produce in the 9.5 hours be x.
than the equation becomes
x = 9.5 × 42.5
x = 403 . 75 tons
403 . 75 tons coal will the mine produces in the 9.5 hours.
Hence proved
Answer:
0.2266
Step-by-step explanation:
We know that the grade point averages of a large population of college students are approximately normally distributed with a mean of 2.4 and a standard deviation of 0.8. The z-score related to 3.0 is computed as (3.0-2.4)/0.8 = 0.75. Therefore the probability that a randomly selected student will have a grade point average in excess of 3.0 is P(Z > 0.75) where Z comes from a standard normal distribution. So, P(Z > 0.75) = 0.2266
Answer:
9400.32 square inches
Step-by-step explanation:
The area of one floor tiles is 92.16
The area of a kitchen floor covered with 102 floor tiles can be calculated as follows
= 102 × 92.16
= 9400.32 square inches
Hence the area is 9400.32 square inches
Divide 138.16 by 3.14. This gives a diameter of 44 meters.
Hope this helped :)
