Answer:
17.81, but I would estimate 17.80 so it doesnt look exact.
Step-by-step explanation:
Using it's concept, it is found that there is a:
- 0.6207 = 62.07% probability of selecting a cow.
- 0.0345 = 3.45% probability of selecting a horse.
- 0.3448 = 34.48% probability of selecting a goat.
- 0% probability of selecting a chicken.
<h3>What is a probability?</h3>
A probability is given by the <u>number of desired outcomes divided by the number of total outcomes</u>.
In this problem, there is a total of 18 + 1 + 10 + 0 = 29 animals, hence:
18/29 = 0.6207.
0.6207 = 62.07% probability of selecting a cow.
1/29 = 0.0345.
0.0345 = 3.45% probability of selecting a horse.
10/29 = 0.3448.
0.3448 = 34.48% probability of selecting a goat.
0/29 = 0.
0% probability of selecting a chicken.

Answer: There are 33 dimes and 17 quarters in my pocket.
Step-by-step explanation:
Step 1: To assign and label the variables.
Suppose,
The number of dimes= x
The number of quarters= y
Step 2: To write the system of equations.
Equation related to the total coins:
x + y = 50 equation 1
Equation related to the total value of the coins:
0.10x + 0.25y = 9.95 equation 2
Step 3: To solve the system of equations.
Multiply equation 1 by 0.10 and then subtract it from equation 2 to eliminate the variable, x.
0.10x + 0.25y – (0.10x + 0.10y)= 9.95 – 5
0.15y = 4.95
y= 33
So, x=50 - 33= 17
Step 4: Therefore, there are 33 dimes and 17 quarters in my pocket.
Answer:
.2813
Step-by-step explanation:
If two events are independent that means that
A*B= A and B
so
let p(b)= x
.09=.32*x
x= .28125
Round this to
.2813
