Answer:
8 units
Step-by-step explanation:
x + 2 = 2x
2 = 2x - x
x = 2
uW = 2(2+2) = 8
Given that
the weight of football players is distributed with a mean of 200 pounds and a standard deviation of 25 pounds.
And we need to find What is the minimum weight of the middle 95% of the players?
Explanation -
Using the Empirical Rule, 95% of the distribution will fall within 2 times of the standard deviation from the mean.
Two standard deviations = 2 x 25 pounds = 50 pounds
So the minimum weight = 200 pounds - 50 pounds = 150 pounds
Hence the final answer is 150 pounds.
Answer:
D. a is equal to 
Step-by-step explanation:
Let us assume that segment PQ is 8 units, so that its midpoint M is at 4 units to both P and Q.
Given that X is the midpoint of PM, this implies that X is at 2 units to both P and M.
Then;
PX = aPQ
⇒ = a x 8
= 8a
Therefore, a must be equal to , so that;
PX = 8a
= 8 x
= 2 units
Thus, a is equal to is the correct option.
Answer:
1.) 5^7 2.) 4^a+b 3.) a^c+d
Step-by-step explanation:
If the exponents are number, you can add the numbers together. Do <u>not</u> add the base numbers. ( Ex: 3 + 4 = 7 )(problem 1)
If the exponents are variables, indicate that you are adding the variables by putting an addition sign between the letters.
