Answer:
(a) 0.5184
(b) 0.0784
(c) 0.4816
Step-by-step explanation:
According to the given estimation over a 1-year period, 18% of cars will need to be repaired once, 7% will need repairs twice, and 3% will require three or more repairs.
So, the probability that a car need repair once = 18/100=0.18 ...(i)
The probability that a car needs repair twice = 7/100=0.07 ...(ii)
The probability that a car needs repair thrice or more = 3/100=0.03 ...(iii)
From equations (i), (ii), and (iii), the probability that a car needs repair = (0.18+0.07+0.03) = 0.28 ...(iv)
The probability that a car doesn't needs repair = 1-(0.18+0.07+0.03)= 1-0.28=0.72 ....(v)
Given that I own two cars, denoting the cars by A and B.
(a) The probability that neither will need repair=(Probability that car A doesn't need repair) and (Probability that car B doesn't need repair)
=0.72 x 0.72 [ from equation (v)]
=0.5184
(b) The probability that both will need repair = (Probability that car A needs repair) and (Probability that car B needs repair)
=0.28 x 0.28 [ from equation (iv)]
=0.0784
(c) The probability that at least one car will need repair= 1 - (The probability that neither will need repair)
=1-0.5184 [ by using part (a)]
=0.4816

Write equations for the horizontal and vertical lines passing through the point (4, -5).
horizontal line: 0
OO
Х
vertical line:
Answer:
Horizontal line: y=-5
Vertical line: x = 4
Step-by-step explanation:
As we have to determine the equations for the horizontal and vertical lines passing through the point (4, -5).
To determine the equation for the horizontal line passing through the point (4, -5), we must observe that the horizontal line will always have the same y-value regardless of the x-value.Therefore, the equation of the horizontal line passing through the point (4, -5) will be: y=-5
To determine the equation for the vertical line passing through the point (4, -5), we must observe that the vertical line will always have the same x-value regardless of the y-value.Therefore, the equation of the vertical line passing through the point (4, -5) will be: x=4
Hence:
Horizontal line: y=-5
Vertical line: x = 4

7. The graph of the linear function is shown on the coordinate grid below.
Answer: C . The slope is -4/3 and the y-intercept is 4.
Step-by-step explanation:
Using the two given points, we will use them to evaluate the slope and the y intercept.
(-1.5,6)
( 4.5,-2)
To find the slope we will find the difference in the y coordinates of the points and divide it by the difference in the x coordinates of the point.
6-(-2) = 8
-1.5 - 4.5 = -6
Slope : 8/-6= -4/3.
Since the slope is -4/3, we will use the formula y= mx + b to find the y intercept. In the formula y= mx + b, the slope is m and b is the y intercept.
Use one of the given points, and input its x and y values into the formula including the slope to solve for b(the y-intercept).
We will use the point, ( -1.5,6)
6 = -4/3(-1.5) + b
6 = 2 + b
-2 -2
b = 4.
b is indeed equal to 4 because it even indicates on the graph that the y intercept is 4 which is where x is equal to 0.

f(x) = 2x4 – 14x3 + 33x2 – 26x
Given that x = 3 + i is a solution of the equatio
f(x) = 0, solve f(x) = 0 completely.
Answer:
x = 0, 2, 5/2 ± 1/2i
Step-by-step explanation:
I'm not really sure what the question is asking but I'm going to assume you want to find the zeroes of the function.
0 = 2x^4 - 14x^3 + 33x^2 - 26x
~Factor
0 = x(x - 2)(2x² - 10x + 13)
~Set factors to equal 0 and solve
x - 2 = 0
x = 2
2x² - 10x + 13 = 0
~Use quadratic formula
x = 0, 5/2 ± 1/2i
Best of Luck!

Does the equation y+3=2(x+9) include the point (-6,3)?
Please explain how you got the answer! :3
Answer:
Step-by-step explanation:
if it includes the point should verify the equation
substitute x= -6 and y=3 in the equation
3+3 = 2 ( -6+9) calculate
6 = 6 is true! so YES the equation includes the point

Answer:
The volume of the figure is 126 cubic cm
Step-by-step explanation:
The figure consists of two rectangular prisms of dimensions 6 x 7 x 1 and 3 x7 x 4 respectively.
Calculate the first volume:
[tex]V_1=6~cm\cdot 7~cm\cdot 1~cm= 42~cm^3[/tex]
[tex]V_1= 42~cm^3[/tex]
Calculate the second volume:
[tex]V_2=3~cm\cdot 7~cm\cdot 4~cm= 84~cm^3[/tex]
[tex]V_2= 84~cm^3[/tex]
The total volume of the figure is the sum of both volumes:
[tex]V_t=V_1+V_2=42~cm^3+84~cm^3=126~cm^3[/tex]
The volume of the figure is 126 cubic cm
