The answer is 882 because if you take answer choices A, B, and C, and divide them by 6, none of them come out to a whole number. However, D, 882, comes out to 882/6= 147. Since it is a whole number, 882 is a multiple of 6.
Answer:
1
Step-by-step explanation:
There are 2 categories male and female and 1 attribute those who text during driving so the number of cells is 2*1= 2
And degrees of freedom is found by subtracting 1 from k= k-1= 2-1= 1 where k is the number of the categories
The degrees of freedom for this chi square test of proportions is 1
The critical value for ∝= 0.05 is .χ²≥ χ²(0.05,1)= 3.84
The critical value for ∝= 0.01 is .χ²≥ χ²(0.05,1)= 2.71
Ok so d is across from angle 70, thiat means that are equal, so d=70
then you can easily tell angle e is 180 - d, Wich is 110, so angle e is 110
angle a plus angle 70 is 90 degrees, so 90-70=20, so angle a is 20
it says angle b plus angle a is 90, we know angle a is 20, so 20plus 70 equals 90, so angle b is 70 degrees
angle b plus angle c equals 90, so we know b is 70. that makes angle c 20

Explanation:
The factors of 60 are 1 and 60, 2 and 30, 3 and 20, 4 and 15, 5 and 12, and 6 and 10.
The next clue eliminates every number except 5, 10, 15, 20, 30, and 60.
5, 10, 15 are less than 20 and eliminated (60 is eliminated because it is more than 50).
20 is eliminated because it is not greater than itself and so Mrs. Smith must be 30.
