Answer:
Missing side = x+2
Step-by-step explanation:
The perimeter of the classroom, 6x+3, is equal to the 4 side lengths added up.
In their first line of work, the first plus sign should be an equal sign as follows:
6x+3 = 3x+1+x+x+?
simplify
6x+3 = 5x+1+?
subtract (5x+1) from both sides
x+2 = ?
There's the length of the missing side.
Answer:
area = 13.8 cm²
Explanation:
The area of the triangle can be calculated using the following rule:
area of triangle = (1/2) * base * height
In the given:
base of triangle = 6.9 cm
height of triangle = 4 cm
Substitute with the givens in the above equation to get the area as follows:
Area = (1/2) * (6.9) * (4)
Area = 13.8 cm²
Hope this helps :)
3x+4y=36
2x-y=2
<em><u> </u></em><em><u>=</u></em><em><u>x-7y</u></em><em><u>=</u></em><em><u>3</u></em><em><u>4</u></em>
F(X) = 4x - 5
G(X) = 6x - 3
F(x) - G(x)
(4x - 5) - (6x - 3)
4x - 5 - 6x + 3
-2x - 2
-2(X + 1).
I believe this would be the simplified solution.
Answer:
The probability of of a randomly chosen student being exactly 21 years old.
= 1.293
Step-by-step explanation:
<u><em>Step(i):-</em></u>
<em>Given Population size n = 500</em>
<em>Mean of the Population = 20 years and 6 months</em>
<em> = </em>
<em></em>
<em>Standard deviation of the Population = 2 years</em>
Let 'X' be the range of ages of the students on campus follows a normal distribution
Let x =21


<em>The probability of a randomly chosen student being exactly 21 years old.</em>
<em>P( Z≤21) = 0.5 + A( 0.2) </em>
= 0.5 +0.793
= 1.293
