Lengths of full-term babies in the US are Normally distributed with a mean length of 20.5 inches and a standard deviation of 0.9
mash [69]

Answer:

66.48% of full-term babies are between 19 and 21 inches long at birth

Step-by-step explanation:

Normal Probability Distribution:

Problems of normal distributions can be solved using the z-score formula.

In a set with mean \mu and standard deviation \sigma, the z-score of a measure X is given by:

Z = \frac{X - \mu}{\sigma}

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 p-value, we get the probability that the value of the measure is greater than X.

Mean length of 20.5 inches and a standard deviation of 0.90 inches.

This means that \mu = 20.5, \sigma = 0.9

What percentage of full-term babies are between 19 and 21 inches long at birth?

The proportion is the p-value of Z when X = 21 subtracted by the p-value of Z when X = 19. Then

X = 21

Z = \frac{X - \mu}{\sigma}

Z = \frac{21 - 20.5}{0.9}

Z = 0.56

Z = 0.56 has a p-value of 0.7123

X = 19

Z = \frac{X - \mu}{\sigma}

Z = \frac{19 - 20.5}{0.9}

Z = -1.67

Z = -1.67 has a p-value of 0.0475

0.7123 - 0.0475 = 0.6648

0.6648*100% = 66.48%

66.48% of full-term babies are between 19 and 21 inches long at birth

3[5x - 4] - [-30 - 45x]
Nimfa-mama [501]
3(5x - 4) - (-30-45x)
= 15x - 12 + 30 + 45x <- Distributive Property
=60x + 18 <- Combine Like Terms

If you're trying to solve for 0:

0 = 60 x + 18
-18 = 60x <- Subtracted 18 from both sides
x = \frac{-18}{60} = \frac{-9}{30} <- Divided both sides by 60 and then simplified.

x = \frac{-9}{30} <- Fraction Form
x = -0.3 <- Decimal Form

Give Brainliest for simple answer plz :P

Bas_tet [7]

Step-by-step explanation:

use Pythagoras theorem,

{a}^{2}  +  {b}^{2}  =  {c}^{2}

{6}^{2}  +  {8}^{2}  =  {c}^{2} \\ 36 + 64 =  {c}^{2}  \\ c = \sqrt{100 }   \\ c = 10
