Answer:
D)the time (in hours) a 4-year-old spends unsupervised per day
Step-by-step explanation:
Given that 4-year-olds in a certain country average 3 hours a day unsupervised and that most of the unsupervised children live in rural areas, considered safe
X - the time (in hours) a 4-year-old spends unsupervised per day
X is N(3,1.8)
Answer:
You need to plot the points at (1.5, 0) and (0,-3)
Step-by-step explanation:
If you would like to know what is 3/8 written as a percent, you can calculate this using the following steps:
3/8 = 375/1000 = 0.375
0.375 * 100 % = 37.5%
The correct result would be 37.5%.
I will take M as molly and S as her sister
M=x-5
S=x
M+S=37
X-5+x=37
2x-5=37
Now you add 5 on both sides so you get 2x=37+5
-5 on other becomes 0 because when you add +5 and -5 get cancels out
So I am left with 2x=37+5
2x=42
Than you divide 2 on both side to get x alone so you are left with
X=(42/2)
X=21
Molly’s age equation is x-5
Now you plug x into the equation so you get
21-5
And that’s equal to 16
So Molly’s age is 16 years
