Well the answer would be 13, because 13 plus 4 is 17.
Answer:
Option C
Step-by-step explanation:
From the number line given in the picture,
Blue arrow has the starting point at a = 6 (Dark point) and moving towards negative side of the number line.
Therefore, number line represents a ≤ 6
3a ≤ 3(6)
3a ≤ 18
3a - 11 ≤ 18 - 11
3a - 11 ≤ 7
Therefore, Option C is the correct option.
Answer:
9+11s
Step-by-step explanation:
9+18s-7s
=9+11s
You can't add 9 and 11s because they are different variables
Answer: 2 3/10 hope this helps :)
Step-by-step explanation:
Answer:
Step-by-step explanation:
Given that a simple random sample of 40 ten-gram portions of the food item is obtained and results in a sample mean of x overbarequals2.5 insect fragments per ten-gram portion.
a) By central limit theorem for samples randomly drawn with large sample sizes (atleast 30) the sample mean follows a normal distribution irrespective of the original distribution it belonged to.
b) Mean of X bar = Sample mean = 5
Std error of x bar = s/sqrt n =
c) P( x bar >5.8) = P(Z>)
=0.4930
