Jerry has taken a random sample of students and determined the number of electives that each student in his sample took last year. There were
19 students in the sample. Here is the data on the number of electives the 19 students took: 6, 6, 8, 7,7,7, 8, 9, 10, 8, 7, 6, 9, 6, 8, 7, 9, 7, 10. The
mean of this sample data is 7.63.
What would the mean be for a different random sample of 19 students from the same population?
A.
The second mean would be the same as the first mean
B. The second mean would be higher than the first mean, but within 1 standard deviation
C. The second mean would be lower than the first mean, but within 1 standard deviation
D. There is insufficient data to predict the mean for the second sample.

in the math equation 8 x 7 = 56, the 8 and the 7 are both factors of 56, since in this lesson we will use square tiles to figure out the factors of a whole find as many different arrays as you can, but follow one important rule: all the rows must have the i can make two rows of nine, so 2 and 9 are both factors of 18.

step-by-step explanation:

the largest number of the four options is 1.8 x 10-2

you have it in scientific notation.

1.80 x 10-6   = 0.00000180

1.80 x 10-4   = 0.000180 (bigger, or "less small", than the former one)

so

1.8 x 10-2       = 0.0180. as you see. the "less small", or the biggest one of them all.

as you have negative exponent, it means you are dividing 1.8 by 100 (i.e. moving the dot towards left, two times).

if you had positive exponent for the scientific notation, power of tenths, you would be multiplying times 100 (moving the dot towards right) as below:

1.8 x (10)2 = 180

so. if you have negative exponent in scientific notation, move the dot toward left. if it is positive, toward right as many times the exponent tells you.

company a

step-by-step explanation:

using the linear regression models , it is found that company a   pays about $14 more. but using the same regression (linear) company b pays about $10 more.

so company a pays more than b

answer: 100
