It is 3.40 * 700 and that is equal to 2380.
Answer:
Rational
Step-by-step explanation:
This number is rational because it can be expressed as a ratio between two numbers.
Answer:
C. 95%
Step-by-step explanation:
The Empirical Rule states that, for a normally distributed random variable:
Approximately 68% of the measures are within 1 standard deviation of the mean.
Approximately 95% of the measures are within 2 standard deviations of the mean.
Approximately 99.7% of the measures are within 3 standard deviations of the mean.
In this problem, we have that:
Mean of 1189 points, standard deviation of 397 points.
Percentage between 395 and 1983 points?
395 = 1189 - 2*397
1983 = 1189 + 2*397
So within 2 standard deviations of the mean, which by the Empirical Rule is approximately 95%, and the answer is option C.
Answer:
6%
Step-by-step explanation:
<em>To solve this you need to subtract 607000 by 572000 to see how many people in the population decreased.</em>
607,000- 572,000= 35,000
Then you put 35,000 over 607,000
also you need x over 100
35000/607,000 x/100
Then do cross product property
35,000*100=3,500,000
607,000* x= 607,000x
3,500,000= 607,000x
Then do 3,500,000 divided by 607,000
You get 5.76%
Round to the nearest percent and get 6%
You are finding the square root of 121
*the answer is 11*
because if you times 11 by its self you get 121
