.5
Step-by-step explanation:
.5 times 1/10 is .05. move the decimal over!
Answer:
x = 7.8
Step-by-step explanation:
a^2 + b^2 = c^2
4^2 + 2^2 = c^2
16 + 4 = c^2
c^2 = 20
c = 4.5
a^2 + b^2 = c^2
a^2 + 4.5^2 = 9^2
a^2 + 20.25 = 81
a^2 = 81 - 20.25
a^2 = 60.75
a = 7.8
We first convert the given equation of the line to slope-intercept form, giving us,
y = -2x - 5
The slope is -2 and the y-intercept is -5. For the new line, the slope should also be equal to -2 and the y-intercept be equal to 2. The equation is then equal to,
y = -2x + 2
The probability of loss is
1 - 0.2 - 0.1 = 0.7
To solve the given problem
We can consider,
30% are girls of 30 people
70% are boys in 30 people
In order to get the number, we just multiply the total number
of people with the percentage of the designated target populace.
<span><span>1. </span>30 x 0.3 =
9 girls</span>
<span><span>
2. </span>30 x 0.7 =
21 boys</span>
<span><span>
3. </span>21 boys + 9
girls = 30 people</span>
Hence, there are 21 boys.
