Answer:
The final balance would be $1,038 after 4 years and 5 months.
Step-by-step explanation:
The final balance would be $1,038 and the total compound interest would be $213.
Ok. So first, we calculate the slope!
m=(y2-y1)÷(x2-x1)= (5-2)÷(3-1)=3/2.
Now that we have the slope, we can start to write an equation for the line by plugging in the given points. b is the y-intercept.
y=mx+b.
2=(3/2)1+b
b=2-(3/2)=2-1.5=.5 or 1/2
so the y-int is (0,.5 or 1/2) .
Next, we have to find the x-int.
to do that, we just plug in 0 for the y.
0=1.5x+.5
x=-.5/1.5= (1/3)
so the x-intercept is
(1/3 or .33,0).
so basically this is obviously easy and number 1 is australia and asustralia is the answer too 2
Answer:
0.5
Step-by-step explanation:
Given that height of 7 year old children are normally distributed with mean =49 inches and std deviation = 2inches
Brenda is 50 inches tall
This means her X score is 50
To convert this X score to Z score we use the formula given below
Here we know all the values of x, mu and sigma
Just substitute
Z score
=
Thus Z score of Brenda is 0.5
12 1/2 - 5x = 3 1/3
12 1/2 - 3 1/3 = 5x
9 1/6 = 5x
x = (9 1/6) / 5
x = 1 5/6
1 5/6 pounds
