In a study conducted several years ago, the average farm size in the United States was 47.1 acres. The standard deviation of the sample was 8.6 acres. That data was approximately normally distributed. Determine the range of farm acreage that covers 68% of the farms. 42.8 to 51.4

15.1 to 79.1

29.9 to 64.3

38.5 to 55.7

24

step-by-step explanation:

the graph shows 30% of students walk. 80 students were questioned, so the number that said they walk is

30% × 80 = 0.30 × 80 = 24

hi there!

first we need to find out how much they are adding to each number to make the next number.

ex: 4 + 4 = 8, 8 + 8 = 16, and so on.

so continuing with 32,

32 + 32 = 64

64 + 64 = 128

128 + 128 = 256

256 + 256 = 512

4, 8, 16, 32, 64, 128, 256, 512

the 8th term of the sequence will be 512

hope this ! ~

there would only be 50 odd numbers between 1 and 100 so therefor there would be 50 even so that would only be 50 odd numbers.
