Answer:
X = 15
Step-by-step explanation:
We move all terms to the left:
<em>x+8+2x-(2x+13)=0</em>
We add all the numbers together, and all the variables:
<em>3x-(2x+13)+8=0</em>
We get rid of parentheses:
<em>3x-2x-13+8=0</em>
We add all the numbers together, and all the variables:
<em>x-5=0</em>
We move all terms containing x to the left, all other terms to the right:
<em>x=5</em>
Answer:
the median will be 200.
the mode will be 402 n 398.
the mean will be 400.
The probability that the contestant wins at least one car is 3/5.
<h3>What is the probability?</h3>
Probability refers to a possibility that deals with the occurrence of random events.
The probability of all the events occurring need to be 1.
For 1 car, we consider two possible outcomes:
P(1 car) = 2/6 x 4/5 + 4/6 x 2/5
P(1 car) = 8/15
For no car in either door
P(no car) = 4/6 x 3/5
P(no car) = 2/5
The probability that the contestant wins at least one car is the sum of the probability of one car and the probability of two cars:
P(2 cars) = 2/6 x 1/5
= 1/15
P(1 car) + P(2 cars) = 8/15 + 1/15
= 3/5

Answer:
Step-by-step explanation:
So the Dimensions are:
Height: 300cm
Length: 300cm
Width: 2cm
SA = 2(H*L)+2(H*W)+2(L*W)
= 180000 + 1200 + 1200
= 182400 
OR 18.24

Answer:
a) C x +x +x +3x +3x = 18
b) x = 2
c) 2 cm, 6 cm
Step-by-step explanation:
a) The sum of the lengths of the sides is equal to the length of the perimeter. The appropriate equation is ...
x +x +x +3x +3x = 18
__
b) Simplifying, the equation becomes ...
9x = 18
x = 2 . . . . . divide by 9
__
c) The shorter sides are x = 2 cm.
The longer sides are 3x = 6 cm.
