Answer:
a. Probability = 0.15
b. Probability = 0.3
Step-by-step explanation:
Given
[tex]P(Bedroom) = 0.4[/tex]
[tex]P(Kitchen) = 0.1[/tex]
[tex]P(Bathroom) = 0.2[/tex]
[tex]P(Living\ room) = 0.15[/tex]
Solving (a): Probability of being somewhere else
This is calculated by subtracting the sum of given probabilities from 1.
[tex]Probability = 1 - (0.4 + 0.1 + 0.2 + 0.15)[/tex]
[tex]Probability = 1 - 0.85[/tex]
[tex]Probability = 0.15[/tex]
Solving (b): Probability of being in bedroom or kitchen
This is calculated as:
[tex]Probability = P(Bedroom) + P(Kitchen)[/tex]
[tex]Probability = 0.2 + 0.1[/tex]
[tex]Probability = 0.3[/tex]

The price of fuel may increase due to demand and decrease due to overproduction. Marco is studying the change in the price of two types of fuel, A and B, over time.
The price f(x), in dollars, of fuel A after x months is represented by the function below:
f(x) = 2.27(0.88)x
Part A: Is the price of fuel A increasing or decreasing and by what percentage per month? Justify your answer. (5 points)
Part B: The table below shows the price g(m), in dollars, of fuel B after m months:
m (number of months) 1 2 3 4
g(m) (price in dollars)3.44 3.30 3.17 3.04
Which type of fuel recorded a greater percentage change in price over the previous month? Justify your answer.
Answer:
A. decreasing 12% per month
B. fuel A recorded the greater change
Step-by-step explanation:
Given an equation and a table of values, you want to compare the rates of change each represents.
A.The fuel price is described by ...
f(x) = 2.27(0.88^x)
We recognize this exponential equation to be of the form ...
f(x) = (initial value) × (growth factor)^x
Comparing parts of the equation, we see ...
growth factor = 0.88
The relation between growth factor and growth rate is ...
growth factor = 1 + growth rate
growth rate = growth factor - 1 = 0.88 -1 = -0.12 = -12%
This tells us the rate of change in fuel price is -12% per month.
B.To find the percentage change, we can use the formula ...
percent change = ((new value) / (old value) -1) × 100%
Applied to the first two table values, we have ...
percent change = (3.30/3.44 -1) × 100% ≈ -4.07%
This decrease of 4.07% is less than the decrease of 12% represented by the equation. Type A fuel recorded the greater percentage change.

What is the slope of the line?
Answer:
1
Step-by-step explanation:
Using two points on the line, (0, -3) and (3, 0),
[tex] Slope (m) = \frac{y_2 - y_1}{x_2 - x_1} [/tex]
Let,
[tex] (0, -3) = (x_1, y_1) [/tex]
[tex] (3, 0) = (x_2, y_2) [/tex]
Plug in the values
[tex] Slope (m) = \frac{0 -(-3)}{3 - 0} = \frac{3}{3} = 1 [/tex]
Slope = 1
Given: AOB is a right angle
Prove: mBOC = 90°
O
B
Since
AOB is a right angle, it is 90°. AOB is supplementary to BOC,
so m AOB + m BOC = 180°. By the substitution property of equality,
90 + m BOC = 180°. Applying the subtraction property of equality,
m BOC = 90%.
What statement is missing from the proof?
The missing piece of information in the proof is that m∠DOA and m∠BOC are vertical opposite angles.
How to find vertically opposite angles?We want to prove that m∠BOC = 90°.
We are given that m∠AOB is a right angle triangle. Thus;
m∠BOC must also be equal to 90°
Now, since m∠BOC and m∠AOB are right angles, then it means that we must equally say that m∠DOA and m∠BOC are vertical opposite angles and they are as such equal.
Thus, the missing piece of information in the proof is that m∠DOA and m∠BOC are vertical opposite angles.

Find the average rate of change of g ( x ) = 7 x 2 + 8 x 3 on the interval [-3, 4].
The average rate of change of g ( x ) = 7 x 2 + 8 x 3 on the interval [-3, 4] is 111.
According to the given question.
We have a function g(x) = 7x^2 + 8x^3.
And a interval [-3, 4].
As we know that, the average rate of change of y over an interval between 2 points (a, f(a)) and (b, f(b)) is the slope of the secant line connecting the 2 points.
To calculate the average rate of change between the 2 points we use the formula
f(b) - f(a)/ b - a
Therefore, the average rate of change of g ( x ) = 7 x 2 + 8 x 3 on the interval [-3, 4] is given by
[7(4)^2 + 8(4)^3 - 7(-3)^(2) - 8(-3)^3]/4 + 3
= [112 + 512 - 63 + 216]/7
= 777/7
= 111
Hence, the average rate of change of g ( x ) = 7 x 2 + 8 x 3 on the interval [-3, 4] is 111.

Looking at the equation, we can see that there is a discontinuity at x = 1 (Vertical Asymptote).
The interval given also includes x = 1 as an enclosed value.
Therefore, the MVT does not apply because the equation is not continuous on the interval [-1, 1].

the variable y varies directly as x. when x=20, y=12. what is the value of y when x=15?
Answer:
9
Step-by-step explanation:
The value of y at x =15 is 9.
What is Direct Variation?Two variables are said to be in Direct Variation when increasing one variable the other also increases.
The direct variation is represented by
y ∝ x
y = kx
where k is the proportionality constant
the value of y =12 , x = 20
12 = k * 20
12/20 = k
k = 0.6
The equation becomes
y = 0.6 x
The value of y at x = 15 is
y = 0.6 * 15
y =9
Therefore, the value of y at x =15 is 9.
