Answer:
6 blue marbles
Step-by-step explanation:
Given;
Total number of marbles N = 15
probability of randomly selecting a green marble
P(G) = 1/5
The probability of randomly selecting a green marble, replacing it, and then randomly selecting a blue marble P(G∩B) = 2/25
P(G∩B) = P(G) × P(B)
P(B) = P(G∩B) ÷ P(G)
The probability of selecting a blue marble
P(B) = 2/25 ÷ 1/5 = 2/5
The number of blue marbles N(B) = P(B) × N
N(B) = 2/5 × 15 = 6
There are 6 blue marbles
Answer:
Try 116?
Explanation:
First, let's us know the formula for finding area of a rectangle.
Formula - A = l * w
In the image, it shows the length (12) and width (10)
Length = L
Width = W
Now, what is 12 x 10? 120
Because we need the shaded region and the little box isn't apart of it, we need to find the area of that box to and subtract it from big box
The length is 2 and the width is 2, shown by the image.
2x2 = 4
120-4 = 116
Answer:
397
Step-by-step explanation:
lets say there's an eqn which is y = mx + c, x is the term no. (5, 6 in the egs provided), y is the value corresponding to x (17, 21)
to find the 100th term sequence we need to find m and c. m is how much y changes when x increases by 1
in this case we can find m easily (m = 21-17 = 4)
now we have c left so just sub one of the egs given to what we have alrd found
17 = 4(5) + c
17 = 20 + c
c = - 3
so the eqn is y = 4x - 3, and we can solve for when x = 100
y = 4(100) - 3
y = 397
hope this isn't too confusing :^)
Answer:
5,280
Step-by-step explanation:
Since there are no decimals this number can't be done
