Well if you split 1/4 in half then that will give 1/8. You must also split 0.25 in half which gives 0.125
Now you can multiply that by 5 which gives 5/8. But also the fraction
Now we know that 5/8 = 0.625
√2π / √5 (expand the expression)
√2π / √5 x √5 / √5 (multiply the fractions)
√2π√5 / √5/√5 (calculate and multiply)
solution is √10π/5 so 1.98 round it to the nearest 10 and it'll be 2 so the answer is D
Answer:
0.0228
Step-by-step explanation:
When the distribution is normal, we use the z-score formula.
In a set with mean and standard deviation , the zscore of a measure X is given by:
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
The weight of football players is normally distributed with a mean of 200 pounds and a standard deviation of 25 pounds.
This means that
The probability of a player weighing more than 250 pounds is
This is 1 subtracted by the pvalue of Z when X = 250. So
has a pvalue of 0.9772
1 - 0.9772 = 0.0228
The probability of a player weighing more than 250 pounds is 0.0228
V = V 1 + V 2 + V 3 =
= 4² · 8 + 4² · 12 + 4² ·8 =
= 4² · ( 8 + 12 + 8 ) =
= 16 · 28 = 448
