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
Write the expression 17 4/3 using radicals :)
The expression can be expressed as radicals in terms of [tex]\mathbf{\sqrt[3]{17^4} }[/tex]
A radical expression is an expression that can be written in square root form. It is an opposite form of an exponent and its power determines the root in which it is been evaluated.
Here, we are given:
[tex]\mathbf{\implies 17^{^\dfrac{4}{3}}}[/tex]
The denominator in the power will be the root of the expression given, since it is 3 it will be the cube root raised to the power of 4.
[tex]\mathbf{\implies \sqrt[3]{17^4} }[/tex]

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

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.

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

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.
