Answer: 0.643
Step-by-step explanation:
There are 300 people and 193 were female.
The sample portion that is female is therefore;
= 193/300
= 0.643
<h3>answer</h3>
we assume the height of the triangle is x,
so the base length will be x+4
the triangle area will be area = 1/2 ( base * height)
48 = 1/2 (x + 4) x
96 = x2 + 4x
96 + 4 = x2 + 4x + 4
100 = (x + 2)2
10 = x + 2 (for the square 100, we ignore the -10, minus is meaningless in length )
x = 8
x + 4 = 8 + 4 = 12
so the height for the triangle is 8 unit, base is 12 unit,

Answer:
<u>-21844</u>
Step-by-step explanation:
<u>Finding n</u>
- -16384 = -4(4)ⁿ⁻¹
- 4ⁿ⁻¹ = 4096
- 4ⁿ⁻¹ = 64²
- 4ⁿ⁻¹ = (8²)²
- 4ⁿ⁻¹ = (4³)²
- n - 1 = 6
- n = 7
<u>Finding The Sum</u>
- S₇ = -4(4⁷ - 1) / 4 - 1
- S₇ = -4 (16383) / 3
- S₇ = -65536/3
- S₇ = <u>-21844</u>
Answer:
D
Step-by-step explanation:
Dividing the inequality by 2 to get rid of the coefficient of x we get x < 15.
