Answer:
95% of monthly food expenditures are between $110 and $190.
Step-by-step explanation:
Given : The monthly amounts spent for food by families of four receiving food stamps approximates a symmetrical, normal distribution. The sample mean is $150 and the standard deviation is $20.
To find : Using the Empirical rule, about 95% of the monthly food expenditures are between which of the following two amounts?
Solution :
At 95% of the data is between two standard deviation to left and right of the mean is given by,
To the left side, 
To the right side, 
We have given,
The sample mean 
The standard deviation 
Substitute in the formula,
Therefore, 95% of monthly food expenditures are between $110 and $190.
The answer would be B. Edge
The set of points in space that are a given distance from a given point is called an <u>Edge.</u>
D would be incorrect since it doesn’t have any edges and is like a circle but is 3D. A cylinder is also incorrect since it has curves from top to bottom. C is also incorrect since it only shows one side, which is called the face. That leaves you with edge which would be the correct answer.
Hope this helps! :3
Answer:
15/2
Step-by-step explanation:
when dividing by fractions, we "flip and multiply"-- therefore:
3 ÷ 2\5 = 3 x 5/2
3 x 5/2 = 15/2
I believe the answer would be 6.3 feet if you use Pythagorean theorem
can i have brainliest pls tyyy :)))
Answer:
-9(2p+1)
Step-by-step explanation:
-18p - 9
find the GCF (greatest common factor) for the expression.
-9
then, divide each term by the GCF
-18p / -9 -9 / -9
= 2p = 1
next, put the two terms you get when dividing into the final form of the answer:
GCF on the outside and quotients on the inside
-9(2p+1)
hope this helped! ;)
