A very simple example problem to satisfy the required above is,
"John has 8 apples and 17 oranges. How much more oranges does John has than apple?"
To answer this item, one needs to subtract the number of apples from the number of oranges. This is as shown below,
D = 17 - 8 = 9
The concept of "how much more than" is linked to finding the difference between the numbers.
Answer:
173 bagels were left after the second hour!!
Step-by-step explanation:
The answer would be 30x-10
See the picture to better understand the problem
F________G_______H_______I
we know that
FI=FG+GH+HI-----> solve for GH
GH=FI-FG-HI
FI=7 units
FG=2 units
HI=1 unit
substitute
GH=7-2-1-----> GH=4 units
the answer is
GH=4 units
Answer:
(A) 0.04
(B) 0.25
(C) 0.40
Step-by-step explanation:
Let R = drawing a red chips, G = drawing green chips and W = drawing white chips.
Given:
R = 8, G = 10 and W = 2.
Total number of chips = 8 + 10 + 2 = 20

As the chips are replaced after drawing the probability of selecting the second chip is independent of the probability of selecting the first chip.
(A)
Compute the probability of selecting a white chip on the first and a red on the second as follows:

Thus, the probability of selecting a white chip on the first and a red on the second is 0.04.
(B)
Compute the probability of selecting 2 green chips:

Thus, the probability of selecting 2 green chips is 0.25.
(C)
Compute the conditional probability of selecting a red chip given the first chip drawn was white as follows:

Thus, the probability of selecting a red chip given the first chip drawn was white is 0.40.
