Answers
Answer:
$7.50
Step-by-step explanation:
Divide the 11.25 by 3 (since there are 3 bags) you should get 3.75 now multiply the 3.75 by 2 (since marco need 2) and you get 7.50

A consumer organization estimates that 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. If you own two cars, what is the probability that a) neither will need repair? b) both will need repair? c) at least one car will need repair?
Answers
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

The perimeter of the rectangle below is 64 units. Find the length of side CD.
Write your answer without variables.
Answers
Answer:
CD = 18 units
Step-by-step explanation:
Given a rectangle with length x and width y, the perimeter is:
P = 2x + 2y
Here, we note that x = AB = CD, y = AD = BC, and P = 64 units. So:
2AB + 2BC = 64
We know that AB = 3z and BC = 2z + 2; plug these in:
2 * (3z) + 2 * (2z + 2) = 64
6z + 4z + 4 = 64
10z = 60
z = 6
Now that we've solved for z, we can find AB and, hence, CD because AB = CD.
AB = 3z = 3 * 6 = 18 units
Thus, CD = 18 units, as well.

Find the units of displacement of the point (4,2) to get the image of (7,7). Chapter (transformation) (coordinates) (translation). Please answer my questions correctly. Unnecessary answers will be reported.
Answers
Answer:
The units of the displacement are (3, 5) → T (x + 3, y + 5)
Step-by-step explanation:
The rules of translation of a point
If the point (x, y) is translated h units to the right and k units up, then its image is (x + h, y + k)If the point (x, y) is translated h units to the right and k units down, then its image is (x + h, y - k)If the point (x, y) is translated h units to the left and k units up, then its image is (x - h, y + k)If the point (x, y) is translated h units to the left and k units down, then its image is (x - h, y - k)∵ Point (4, 2) is translated by (h, k)
∵ Its image is (7, 7)
∴ The x-coordinate of the point is increased from 4 to 7
∴ The point is translated to the right by h units
∵ 4 + h = 7
∴ h = 7 - 4 = 3
∴ The point is translated to the right 3 units
∵ The y-coordinate of the point is increased from 2 to 7
∴ The point is translated up by k units
∵ 2 + k = 7
∴ k = 7 - 2 = 5
∴ The point is translated up 5 units
∴ The point is translated 3 units right and 5 units up
∴ The units of the displacement are (3, 5) → T (x + 3, y + 5)

Answers
Answer:
[tex]P=\frac{C}{4} -5[/tex]
Step-by-step explanation:
Step one:
given
cost per drive= $20
additional fee per person= $4
let the number of persons be p
and the total cost be C
The total cost function is expressed as
[tex]C=20+4p[/tex]
Step two:
Required:
We want to make P subject of the cost function
Take 20 to the other side we have
C-20=4p
divide through by 4
P=C-20/4

P=C/4-5
[tex]P=\frac{C}{4} -5[/tex]
x2-11x+18=0 need help!
Answers
Answer:
x = 2 or
x = 9
Step-by-step explanation:
x² - 11x + 18 = 0
x² - 9x - 2x + 18 = 0
x(x - 9) - 2(x - 9) = 0
(x - 2)(x - 9) = 0
x - 2 = 0 or x - 9 = 0
x = 2 or x = 9
Thus, x = 2 or 9
-TheUnknownScientist
Answer:
x = 2, x = 9
Step-by-step explanation:
Given
x² - 11x + 18 = 0
Consider the factors of the constant term (+ 18) which sum to give the coefficient of the x- term (- 11)
The factors are - 2 and - 9 , since
- 2 × - 9 = + 18 and - 2 - 9 = - 11 , thus
(x - 2)(x - 9) = 0 ← in factored form
Equate each factor to zero and solve for x
x - 2 = 0 ⇒ x = 2
x - 9 = 0 ⇒ x = 9

what’s the answer??
Answers
Answer: The answer is x=0
Step-by-step explanation:
Rewrite the equation as a trinomial.
x 2 + 12 x + 0
Move 0 to the right-hand side.
x 2 + 12 x = 0
Divide the coefficient of the x
-term by 2, then square the result. Add the result to both sides.
12 /2 = 6 ;6^2 = 36
x 2 + 12 x + 36 = 36
Factor the perfect square trinomial
x 2 + 12 x + 36
on the left-hand side.
( x + 6 ) 2 = 36
Take the square root of both sides and solve for x .
√ ( x + 6 )^ 2 = ± √ 36 =
x+ 6 = ± 6
x = − 6 + 6 = 0
x = − 6 − 6 = − 12
Check
If x = 0 :
( 0 ) ^2 + 12 ( 0 ) = 0
0 = 0
If x = − 12 :
( − 12 ) ^2 + 12 ( − 12 ) = 0
144 − 144 = 0
0 = 0
