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

Choose the correct simplification of the expression d3 ⋅ d5. <br> d <br> d15 <br> d2 <br> d8

irga5000 [103]

Answer:

Option D is correct

$d^{8}$

Step-by-step explanation:

Given the expression: $d^3 \cdot d^5$

Use exponents rule:

$x^a \cdot x^b = x^{a+b}$

Apply the rule in the given expression;

$d^3 \cdot d^5$

$d^{3+5}$

$d^{8}$

Therefore, the correct simplification of the given expression is, $d^{8}$

Find a formula for the nth term of the geometric sequence. Assume the n begins with 1. a1=18, a2=9

LUCKY_DIMON [66]

Answer:

Option E

Step-by-step explanation:

Explicit formula of a geometric sequence is,

$T_n=a_1(r)^{n-1}$

Here, $a_1=$ First term

$r=$ common ratio

$n=$ number of terms

If, $a_1=18$ and $a_2=9$

Common ratio of the sequence $r=\frac{a_2}{a_1}$

$r=\frac{9}{18}$

$r=\frac{1}{2}$

By substituting these values in the formula,

$T_n=18(\frac{1}{2} )^{n-1}$

Therefore, Option E is the answer.

97 1/2 miles in 3/2 hour: miles?

SashulF [63]

Answer:

97 1/2 miles in 1 hour and 30 minutes.

Step-by-step explanation:

I think your asking how many miles he travels in 3/2 of an hour.

He travels 65 miles in 1 hour but because he's been traveling 3/2 of an(=1 hour and 30 minutes because 2 is 1 hour so he has 1 whole or one hour and still has 1/2 so 1/2 of an hour=30 minutes.

He travels 32.5 miles in 30 minutes. And that should be your answer he travels 32.5 miles every 30 minutes.

Here's calculations.

32.5 x 1(30 minutes)=32.5

32.5 x 2(1 hour)=65

32.5 x 3(1 hour and 30 minutes)=97.5

Hope it helps have a great day:)
