Answer:
An event can have a probability of 3/2 is not true
Step-by-step explanation:
The probability of an event happening is between 0 and 1 inclusive.
A probability of 1 means the event is certain to happen or 100%
You cannot have a probability greater than 1 so
An event can have a probability of 3/2 cannot happen

What is the surface area of the rectangular prism below?
Answer:
Step-by-step explanation:
The surface area of a rectangular prism calculator gives us the answer: A = 2 * l * w + 2 * l * h + 2 * w * h = 2 * 8 ft * 6 ft + 2 * 8 ft * 5 ft + 2 * 6 ft * 5 ft = 236 ft² .
CALCULUS: For the function whose values are given in the table below, the integral from 0 to 6 of f(x)dx is approximated by a Reimann Sum using the value at the left endpoint value of each of three intervals with width 2.
x 0 1 2 3 4 5 6
f(x) 0 0.25 0.48 0.68 0.84 0.95 1
The approximation is:
A. 2.64
B. 3.64
C. 3.72
The table gives values of f(x) at various x in the interval [0, 6], and you have to use them to approximate the definite integral,
∫₀⁶ f(x) dx
with a left-endpoint sum using 3 intervals of width 2. This means you have to
• split up [0, 6] into 3 subintervals of equal length, namely [0, 2], [2, 4], and [4, 6]
• take the left endpoints of these intervals and the values of f(x) these endpoints, so x ∈ {0, 2, 4} and f(x) ∈ {0, 0.48, 0.84}
• approximate the area under f(x) on [0, 6] with the sum of the areas of rectangles with dimensions 2 × f(x) (that is, width = 2 and height = f(x) for each rectangle)
So the Riemann sum is
∫₀⁶ f(x) dx ≈ 2 ∑ f(x)
for x ∈ {0, 2, 4}, which is about
∫₀⁶ f(x) dx ≈ 2 (0 + 0.48 + 0.84) = 2.64
making the answer A.
Solve for x in the figure below
Answer:
x = 6.8
Step-by-step explanation:
7x + 36 = 12x + 2 (alternate interior angles are congruent)
Collect like terms
7x - 12x = -36 + 2
-5x = -34
Divide both sides
-5x/-5 = -34/-5
x = 6.8

Step-by-step explanation:
If you count all the options, there are 36 options/number combinations in all.
However, the only combination that would equal 12 is 6,6
This is because 6 + 6 = 12. No other numbers together would equal 12.

9514 1404 393
Answer:
f(x²) = x² +5(f(x))² = x² +10x +25Step-by-step explanation:
Put the argument in place of x and evaluate the desired expression.
__
1. f(x²) = x² + 5 . . . . . . straight substitution for x
__
2. (f(x))² = (x +5)²
= (x +5)(x +5) = x(x +5) +5(x +5) = x² +5x +5x +25
(f(x))² = x² +10x +25
g(x) = 5x - 12x2 + 3
The factor of the function will be (4x - 3) and (3x + 1). The graph of the function is shown below.
What is a factorization?It is a method for dividing a polynomial into pieces that will be multiplied together. At this moment, the polynomial's value will be zero.
The function is given below.
g(x) = 5x - 12x² + 3
Then the function can be written as
g(x) = - 12x² + 5x + 3
Then the factor of the function will be
g(x) = 0
Then we have
- 12x² + 5x + 3 = 0
12x² - 5x - 3 = 0
12x² - 9x + 4x - 3 = 0
(4x - 3)(3x + 1) = 0
x = -0.33 and 0.75
Then the graph of the equation will be given below.

An appliance salesperson earned $32.80 in commission for selling a refrigerator for $820. At that rate, how much would the salesperson earn in commission for selling a microwave oven for $340?
Answer:
Salesperson would earn $13.6 in commission for selling a microwave oven for $340.
Step-by-step explanation:
We are given that an appliance salesperson earned $32.80 in commission for selling a refrigerator for $820.
We have to find how much would the salesperson earn in commission for selling a microwave oven for $340.
Firstly, we will the find the rate at which the salesperson gets a commission in % terms.
So, Percentage rate of commission is given by;
Rate of commission=(Commission earned ÷ Selling Price of refrigerator) 100
= = = 4%
Now, this rate will be used to find the commission earned on selling a microwave oven for $340, i.e;
Commission earned for selling a microwave oven = 4% of Selling price of microwave oven
= = $13.6
Therefore, salesperson would earn $13.6 in commission for selling a microwave oven for $340.

Convert to slope intercept form 4x+5y=-20
Answer:
Slope-intercept form is: y=mx+b. Where m = slope or rise/run & b = y-intercept or where the line crosses the y axis. So for 4x + 5y = 20 the slope intercept form is y = -4x/5 + 4.
Step-by-step explanation:
Answer:
y = -4/5x - 4
Step-by-step explanation:
4x + 5y = -20
-4x -4x
5y = -4x - 20
divide it all by 5
y = -4/5x - 4

In exercises 4-6, a survey reported that 235 of the 500 voters in a sample voted for candidate A and the rest voted for candidate B?
4. What percent of the voters in the sample voted for candidate A? What percent of the voters in the sample voted for candidate B?
5. What is the margin sampling error? Round your answer to the nearest tenth of a percent.
6. For each candidate, give an interval that is likely to contain the exact percent of all voters who voted for the candidate.
7. For #6, can you determine which candidate won? Explain.
4.
Total voters = 500
Number of voters that voted for candidate A = 235
Number of voters that voted for candidate B = 500 - 235 = 265
Percent of voters that voted for candidate A
= 235
500
× 100%
= 23500
500
= 47%
Percent of voters that voted for candidate B
= 265
500
× 100%
= 26500
500
= 53%
5.
Margin sample error = % of candidate B - 5 of candidate A
= 53% - 47%
= -/+ 6%
Margin sample error = + 6.0% or - 6.0%
6.
Candidate A interval
= 47 ± 0.5
= 46.5% or 47.5%
Candidate B interval
= 53±0.5
= 52.5% or 53.5%
7.
Candidate with the highest percentage win.
Therefore, candidate B won
