Answer:
13/102
Step-by-step explanation:
In a standard deck of 52 cards, there are 13 black spades, 13 black clubs, 13 red diamonds and 13 red hearts. There are 26 <u>black </u>cards in the deck of 52 cards.
Probability of drawing a black card = 26/52 = 1/2
Suppose we drew the black card. There are now <u>only 51</u> cards left in the deck. ALL of the hearts are still there - <u>13</u> of them.
Probability of drawing a heart from this deck of 51 = 13/51
In general, for the probability of event A <u>and then</u> event B, we multiply.
1/2 x 13/51 = 13/102
Step-by-step explanation:
Using the given formula :
I = P × R × T
I = 80000 × 15/100 × 4
I = $48000
He saves = 48000 +80000 = $128000
Answer:
Domain is ![[0,18]](https://tex.z-dn.net/?f=%5B0%2C18%5D)
Average rate of change of bacteria per minute is -3333.33.
Step-by-step explanation:
Domain is the possible values of
.
From the graph, it's clear that the
values ranges from 0 to 18 as the end points of the graph are
and 
So, domain of the function is
.
Now, average rate of change is negative as there is bacteria decay.
Average rate of change is given as the negative ratio of y intercept to the x intercept.
Here, x-intercept is 18 and y-intercept is 60000.
So, average rate of change is given as,

Therefore, average rate of change of bacteria per minute is -3333.33.
