1 answer:

7 0

1/4 an hour is 60 divided by 4 times 1 which is 15 minutes.
3/5 an hour is 60 divided by 5 times 3 which is 36 minutes.
15 plus 36 equals 51 minutes which is less than 1 hour.

Answer:

probability of getting four head consecutively is 0.2

Step-by-step explanation:

in an experiment coin is flipped 4 times.

given, coin landed heads up more than two times

outcomes of coin landed heads up more than two times =

SAMPLE SPACE : [ {HHHT}{HHTH}{HTHH}{THHH}{HHHH} ]

chance of getting 4 heads = 1 (HHHH)

Probability = $\dfrac{1}{5}$

hence the probability of getting four head consecutively is 0.2

a rectangular pool is 20 ft wide and 50 ft long. the deck is the same width all the way around the pool. the total area of the d

Alex

First, we need to get the total area of the rectangular pool.
Area = l * w
Area = 20 ft * 50 ft
Area = 1000 ft^2

Then the deck is 456 ft^2 with the width of 20ft, the same as the rectangular pool.

Area = l * w
456 = l * 20
l = 456 / 20
l = 22.8 ft.

So the walkway is 22.8ft wide.

Answer:

Step-by-step explanation:

Based on what you have here as the slope we can set the slope formula equal to 34 using the points (0, 8) and (8, c) to solve for c, then use the points (0, 8) and (a, 5) to solve for a.

c first:

$\frac{c-8}{8-0}=34$ and
