Answer:
$92.23
Step-by-step explanation:
If she spent 213.20 in the first month and Mica's total only counts for two months, then you can subtract 213.20 from 305.43 to see how much she spent in the second month.
305.43 - 213.20 = 92.23
Answer:
A pound of a JELLY BEANS cost $2.5
A pound of TRAIL MIX cost $1.5
Step-by-step explanation:
From the question, we can draw out two equations and solve them simultaneously.
We should make some mild assumptions to make it easier:
Let Jelly beans be j
Let Trail mix be t
Therefore, we can extract these equations.
5j + 3t =$ 17 ...........i
2j + 12t = $ 23...…..ii
Let's Multiply equation (I) by 4 so that we can easily eliminate.
20j + 12t = $ 68..... iii
Let equation (iii) minus equation (ii)
18j + 0t = $45
18j = $45
j = $45/18
j = $2.5
A pound of a JELLY BEANS cost $2.5
Let's substitute j= $2.5 in EQUATION (I) so as to solve for TRAIL MIX.
5j + 3t =$ 17
5(2.5) + 3t = 17
12.5 + 3t = 17
3t = 17 - 12.5
3t = 4.5
t = $1.5
A pound of TRAIL MIX cost $1.5
E(X) = 0(0.7) + 1(0.2) + 2(0.1) = 0.2 + 0.2 = 0.4
The expected daily loss due to blackouts = 0.4 * $500 = $200
Var(X) = 0(0.7 - 0.4)^2 + 1(0.2 - 0.4)^2 + 2(0.1 - 0.4)^2 = 0.04 + 0.18 = 0.22
The expected daily variance due to blackouts = 0.22 * $500 = $110
Given:
Consider the given function is:
To find:
The average rate of change of the function over the interval 
.
Solution:
The average rate of change of the function f(x) over the interval [a,b] is:
We have,
At 
,
At 
,
Now, the average rate of change of the function f(x) over the interval is:
Therefore, the average rate of change of the function f(x) over the interval is -3.
The first quadrant is the upper right hand corner of the graph where both y and y are positive
the second quadrant in the upper left hand corner includes negative values of x and positive values of y
the third quadrant the lower he as corner includes negative values of both x and y
the fourth quadrant the lower right handed corner the x is positive and the y is negative
hope this helps, can i have brainliest please
