Answer:
40cm² there you go
Step-by-step explanation:
Area =side×side so 8×5=40
The percent of students that are aged 19 years or more is determined as 84%.
<h3>One standard deviation below the mean</h3>
In a normal distribution curve 1 standard deviation below the mean is defined as follows;
- 1 std below mean : M - d = 16%
M - d = 20.6 yrs - 1.3 yrs = 19.3 years ≈ 19 years
19 years or more will occur at (M - d) + (M) + (M + 2d) = 100% - (M - d)
= 100% - 16%
= 84%
Thus, the percent of students that are aged 19 years or more is determined as 84%.

Answer:
perpendicular
Step-by-step explanation:
4y= 2x-5
y = 1/2 x - 5/4
slope₁ = 1/2
2x+y =3
y = -2x + 3
slope₂ = -2
slope₂ = - 1 / slope₁
Answer:
diagonal is 14 m
Step-by-step explanation:
We are given;
- The area of a square garden as 98 m²
We are required to determine the diagonal of the square.
We know that;
Area of a square = s² , where s is the side of the square
Therefore;
s² = 98
Thus;
s = √98
To get the diagonal
s² + s² = diagonal squared
Hence;
Diagonal squared = (√98)² + (√98)²
= 98 + 98
= 196
Thus;
Diagonal = √196
= 14 m
Thus, the diagonal is 14 m
