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:
[tex]P(A \cap B) = P(A) \times P(B)[/tex]
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
[tex]P(A) = \frac{4}{10}[/tex]
Probability of selecting a number less than or equal to 3:
Three numbers(1,2,3) out of 10. So
[tex]P(B) = \frac{3}{10}[/tex]
Probability of both:
[tex]P(A \cap B) = P(A) \times P(B) = \frac{4}{10} \times \frac{3}{10} = \frac{12}{100} = 0.12[/tex]
0.12 = 12% probability of first selecting a PRIME number, replacing it, then selecting a number less than or equal to 3

9/2+ 3(4 – 1) – 7 + 23
Step 1: = 9/2+ 3(3) — 7 + 23
Step 2: = 9/2 + 3(3) - 7 + 8
Step 3: =15/2 (3) — 7+8
Step 4: =45/2 - 7+8
Step 5: =31/2 +8

Step-by-step explanation:
For this exponential function what is the output value (y) when the input value (c) is 3?
Answer:
y = 40
Step-by-step explanation:
Given, y = 5 * 2^x
If x = 3, y would be:
Substitute the value of x into the given function.
Thus,
y = 5*2³
y = 5*8
y = 40

There were 22,180 seats in a stadium. There are 85 sections with an equal number of seats in each and the remaining seats are floor level. How many seats are on the floor?
Answer:
Step-by-step explanation:
There are multiple solutions.
If each section has n seats, the floor has 22,180-85n seats.
22,180/85 ≅ 260.9, so each section has at most 260 seats.
If each section has 260 seats, the floor has 22,180-85×260 = 80.

Turn this improper fraction in mixed numbers.23/7
Answer:
3 2 /7
Step-by-step explanation:
Divide using long division. The whole number portion will be the number of times the denominator of the original fraction divides evenly into the numerator of the original fraction, and the fraction portion of the mixed number will be the remainder of the original fraction division over the denominator of the original fraction.
Identify in the given expressions, terms which are not constants. Give their numerical coefficients.
(i) 5x – 3
(ii) 11 – 2y2
(iii) 2x – 1
Given:
The expression are
(i) [tex]5x-3[/tex]
(ii) [tex]11-2y^2[/tex]
(iii) [tex]2x-1[/tex]
To find:
The terms which are not constants and their numerical coefficients.
Solution:
Constants: The terms which are free from variables.
Numerical coefficient: Number multiplied with a variable.
(i) [tex]5x-3[/tex]
Constant = -3
Term which is not constant = 5x
Numerical coefficient = 5
(ii) [tex]11-2y^2[/tex]
Constant = 11
Term which is not constant = [tex]-2y^2[/tex]
Numerical coefficient = -2
(iii) [tex]2x-1[/tex]
Constant = -1
Term which is not constant = 2x
Numerical coefficient = 2
Therefore, the terms which are not constants are [tex]5x,-2y^2,2x[/tex] respectively and their numerical coefficients are 5, -2, 2 respectively.

Glen needs to select the shortest length nail available to build a small bird house. Of the following for sizes available which one should he select: A) 1 3/5 inches B) 1 5/8 inches C) 1 2/3 inches D) 1 3/4 inches
Answer:
B) 1 7/8
Step-by-step explanation:
1. first, if you have 16/8 then it would be 2, but since it is 15/8 you need to minus 15 and 8
2. 15-8=7, now you only have 7
3. last, since you only have 7 then it is 1 whole and 7 8ths
4. 1 7/8 is your answer.

What is the value of x in the equation -2/9x2/5 ?
A. -1 4/5
B. -5/9
C. 5/9
D. 1 4/5
Answer:
-1 4/5
Step-by-step explanation:
-2/9x = 2/5
(multiply both equations by 9 and 5)

(divide both equations by -10)
x = - 18/10
Simplify:
x= - 9/5
= - 1 4/5
