A bag contains tiles number 1-10. What is the probability of first selecting a PRIME number, replacing it, then selecting a numb

andrezito [222]

Answer:

0.12 = 12% probability of first selecting a PRIME number, replacing it, then selecting a number less than or equal to 3

Step-by-step explanation:

A probability is the number of desired outcomes divided by the number of total outcomes.

Probability of independent events:

Suppose we have two events, A and B, that are independent. The probability of both happening is given by:

$P(A \cap B) = P(A) \times P(B)$

In this question:

Event A: Selecting a prime number.

Event B: Selecting a number less than or equal to 3

Probability of selecting a prime number:

Between 1 and 10, we have 4 prime numbers(2,3, 5 and 7), out of 10. So

$P(A) = \frac{4}{10}$

Probability of selecting a number less than or equal to 3:

Three numbers(1,2,3) out of 10. So

$P(B) = \frac{3}{10}$

Probability of both:

$P(A \cap B) = P(A) \times P(B) = \frac{4}{10} \times \frac{3}{10} = \frac{12}{100} = 0.12$

0.12 = 12% probability of first selecting a PRIME number, replacing it, then selecting a number less than or equal to 3

Without dividing or multiplying, explain why 0.8 divided by 0.7 is greater

Art [367]

Answer:

It is greater because when you divide decimals you move the decimal which would automatically make the product less than the quotient.

Holly has $10.00 . she saw a purse in a catalog that was marked 14.95 plus 5% sales tax . how much more did holley need to buy t

vladimir1956 [14]

For this case we will first look for the total cost of the purse.
We then have the following rule of three:
14.95 $ -----> 100%
x -------------> 105%
Clearing x we have:
x = (105/100) * (14.95)
x = 15.6975 $
The amount needed to buy the purse is:
15.6975 - 10 = 5.6975 $
Answer:
holley needs 5.6975 $ to buy the purse

Complete the table below to find solutions to the linear equation −4x+4y=16.

Rama09 [41]

Step-by-step explanation:

if x=4, then -4x4+4y=16

so, -16+4y=16

so, 4y=16+16=32

so, y=32/4

so, y=8

and x=4
