a study studied the birth weights of 1,999 babies born in the United States. The mean weight was 3234 grams with a standard devi
Aleks [24]

Answer:

1899

Step-by-step explanation:

The Empirical Rule states that, for a normally distributed random variable:

68% of the measures are within 1 standard deviation of the mean.

95% of the measures are within 2 standard deviation of the mean.

99.7% of the measures are within 3 standard deviations of the mean.

In this problem, we have that:

Mean = 3234

Standard deviation = 871

Percentage of newborns who weighed between 1492 grams and 4976 grams:

1492 = 3234 - 2*871

So 1492 is two standard deviations below the mean.

4976 = 3234 + 2*871

So 4976 is two standard deviations above the mean.

By the Empirical Rule, 95% of newborns weighed between 1492 grams and 4976 grams.

Out of 1999:

0.95*1999 = 1899

So the answer is 1899

-6x+5y=1<br>6x+4y=-10<br>solve the system below by elimation​
nlexa [21]

Answer:

Y=0.2

X=0.9

Step-by-step explanation:

-6x+5y=1

 +6x -> 5y=1 -> y=0.2

6x+4y=-10

 +6x -> 12x+4y=-10

12x+4*0.2=-10

 12x+0.8=-10

 -0.8

 12x=-10.8

 x=0.9
