7.2 times 4=28.8-10=18.8
she saves 18.8 dollars per week.
18.8 times 12=225.6
after 12 weeks she has saved 225.6 dollars
225.6 times 0.25=56.4
her grandparents giver her 56.4 dollars
56.4+225.6=282
she has 282 dollars
Using the arithmetic formula an = a1 + d(n - 1) to identify the sequence.
an = 5n - 13

The answer is g=37. This is correct
Answer:
A
Step-by-step explanation:
B,.C and D are wrong because
B states all. The hypothesis stated above does not mention all samples
.
C. Mentions a mean. Per the hypothesis, the percentage of defective screens was an actual number and not a mean.
D. The question is not referring to a standard deviation
All angles in a triangle always equal 180 degrees, so to solve this problem you must set 8,3,4 equal to 180. 8x + 3x + 4x = 180. 15x = 180. 180/15 = 12. x = 12. Now you take the value of x and multiply it by the angle you are trying to find. 3(12) = 36.
The measure of the smallest angle is 36.
To check this problem, multiply all the angle ratios by the x value and if it equals 180, it is correct. 8(12) + 3(12) + 4(12) = 180.
