Answer:
The answer matches with option A.
Step-by-step explanation:
We have to find the product of 100,000 and 1,000,000 using scientific notations.
Now, 100,000 can be written as 
and
1,000,000 can also be written as 
.
So, the product will give
100,000 × 1,000,000
= 
= 
= 
So, the answer matches with option A. (Answer)
The coefficient of the term 13a is 13
The coefficient of 6b in expression is a + 6b is 6
<em><u>Solution:</u></em>
<em><u>Given expression is:</u></em>
13a + 6b
We have to find the coefficient of 13a
The coefficients are the numbers that multiply the variables or letters
Here in 13a , a is the variable that is multiplied with number 13
Thus the coefficient of the term 13a is 13
<em><u>Second expression:</u></em>
a + 6b
Here, in 6b , b is the variable that is multiplied with number 6
so 6 is the coefficient
Answer:
Option D
Step-by-step explanation:
A reporter collects a random sample of 50 runners from all the runners who finished the Cherry Blossom Ten Mile Run in 2009 and constructs a 99% confidence interval for the true mean finish time to be (86.05, 99.38) minutes.
Assuming the reporter performed the calculations correctly, which of the following statements are appropriate interpretations of this confidence interval?
We can expect that 99% of confidence intervals created using the same method the reporter used will contain the true mean run time for runners of this race.
Answer:
a) Prepare a frequency table for the data
Step-by-step explanation:
Answer:
Twice.
Step-by-step explanation:
7 times 2 is 14.
So it can only go in 2x.
