2x+5=25
2x=25-5
2x=20
X=20/2
X=10
Answer:
The formula for volume of a cone is area of a circle times height, divided by 3.
Therefore volume is pi times radius squared times height, divided by 3.
V = (3.14)(14)^2 (14)/3
V = (3.14) (196)(14)/3
V = (3.14) (2744)/3
V = 8616.16/3
V = 2872.05333
to the nearest hundredth is 2872.05 cubic yards.
Step-by-step explanation:
Multiply 8.34 by 6 and you'll get 50.04
Using the normal distribution, it is found that a weight of 3125 grams would given a newborn a z-score of −0.75.
<h3>Normal Probability Distribution</h3>
The z-score of a measure X of a normally distributed variable with mean and standard deviation is given by:
- The z-score measures how many standard deviations the measure is above or below the mean.
- Looking at the z-score table, the p-value associated with this z-score is found, which is the percentile of X.
Researching the problem on the internet, it is found that the mean and the standard deviation for the weight of newborns is given as follows:
Hence, the weight associated with Z = -0.75 is given by X:
X - 3500 = -0.75(500)
X = 3125.
