sammy [17]

Answer: $x^3y^9$

Step-by-step explanation:

Reformatting the input :

Changes made to your input should not affect the solution:

(1): Dot was discarded near "7.".

Simplify $\frac{y^2}{x}$

<u>The equation at the end of step 1:</u>

$((x^4)*\frac{y^2}{x} )*y^7$

<u>Multiplying exponential expressions:</u>

2.1 $y^2$ multiplied by $y^7$ $=y^(2+7)=y^9$

Final result is $x^3y^9$

Lilit [14]

Given:
wild turkey ; 12 in the first hour and cumulative number increases by 40% per hour
white-tail deer ; 18 in the first hour and 10 deer each hour after that.

wild turkery: 12 * (1.40)^n-1 ; n is the number of hour
white-tail deer: 18 + 10^n-1 ; n is the number of hour

n wild turkey white-tail deer
1 12 18
2 17 28
3 24 38
4 33 48
5 46 58
6 65 68
7 90 78

It would be hour 7 after sunrise that the cumulative count of the turkeys first exceed the cumulative count of the deer.

A person draws a card from a hat. Each card is one color, with the following probabilities of being drawn: 1/25 for red, 1/20 fo

VARVARA [1.3K]

Probability helps us to know the chances of an event occurring. The probability of pulling a green or red card is 9 / 100.

<h3>What is Probability?</h3>

Probability helps us to know the chances of an event occurring.

P = $\dfrac{Desired \ outcomes}{Posiible \ outcomes}$

The probabilities of different color cards being pulled are 1/25 for red, 1/20 for green, 1/15 for purple, and 1/10 for black Therefore, the probability of pulling a green or red card is,

Probability = 1/20 + 1/25

= (5 + 4) /100

= 9 / 100

Hence, the probability of pulling a green or red card is 9 / 100.
