In a whole hour, a half-hour goes by, two times.
In the first half-hour, 7/8 of a gallon leaks out of the pool.
In the second half-hour, another 7/8 of a gallon leaks out of the pool.
In the whole hour, (7/8 gallon + 7/8 gallon) leaks from the pool.
Can you add those two fractions, and make a single number ?
Answer:
0.01923 or 1.92 %
Step-by-step explanation:
The probability of drawing a queen card out of deck is 4/52
∴ P(Q)= 4/52
there are 4 queens in a deck, one of each suit.
The probability of drawing a diamond card out of deck is 13/52
∴P(D)= 13/52
there are 13 cards in diamond suit (including the three face cards).
The total will remain 52 as he has replaced the first card and have not moved it aside
therefore, the net probability for both scenarios will be defined by calculating both probabilities.
P= P(Q) x P(D)
P= 4/52 x 13/52
P=1/52
P=0.01923 (converting into percentage)
P=0.01923 x 100%
P=1.92 %
Answer: the probability that James draws a queen card as the first card and a diamond card as the second card is 1.92%

Answer: Rectangle
If you let
P = (0,0)
Q = (0,b)
R = (a,b)
S = (a,0)
you'll be able to find that
PQ is a vertical line with undefined slope
QR is a horizontal line with slope 0
so PQ and QR form a right angle as they are perpendicular lines
You'll find this with the other line pairings as well. We'll have four right angles

Answer:
(x, f(x)) = (1, 6), (2, 11), (3, 18), (4, 27)
Step-by-step explanation:
Each figure consists of two small squares and a square that has a side length of 1 more than the figure number. That is, ...
f(x) = (x +1)^2 +2
You can count the squares in figures 1-3. Figure 4 will be 2 more squares than 5^2 = 25, so will be 27 squares.
(x, f(x)) = (1, 6), (2, 11), (3, 18), (4, 27)
