A random number generator is used to create a list of 300 single-digit numbers. Of those 300 numbers, 146 are odd and 154 are ev

Archy [21]

Answer:

0.44

Step-by-step explanation:

The total numbers drawn = 300

Out those 146 are odd and 154 are even.

The number 8 was drawn = 22 times

So, the number of times an even number other than 8 = 154 -22 = 132

The experimental probability = The number of favorable outcomes ÷ The number of possible outcomes.

The experimental probability of an even number other than 8 being generated = $\frac{132}{300}$

Simplify the above fraction to decimal, we get

= 0.44

Therefore, the answer is 0.44

Michael spends a half hour adding water to his pool part of the time at a rate of 15 gallons per minute and the rest of the time

NeTakaya

Answer:

24t + 270 gallons

Step-by-step explanation:

Given that :

Addition rate 1 = 15 gallons per minute

Addition rate 2 = 9 gallons per minute

Total time spent adding water = half an hour = 30 minutes = 0.5 hour

Time spent adding water at faster rate = t

Time spent addition water at slower rate = (30 - t)

Total number of water added to the pool :

Amount of water added = addition rate * time

Hence,

Amount of water added at faster rate :

(15 gal / min) * t = 15t gallons

Amount added at slower rate :

(9 gal / min) * (30 - t) = (270 - 9t) gallons

Total amount of water added to the pool:

15t gallons + (270 - 9t)gallons

15t + 270 + 9t

24t + 270 gallons

What is the slope of the line that passes through the points (-8, -3) and

aleksklad [387]

Answer:

slope of the graph is

$\frac{ - 1}{4}$

Step-by-step explanation:

slope of a graph = (y2 - y1) / (x2 - y1)

1 - (-3) / ( -24 - ( -8 ) )
1 + 3 / -24 + 8
4 / -16
1 / -4
-1 / 4

hence the slope of the graph is

$\frac{ - 1}{4}$

i hope it helped...
