Answer:
Step-by-step explanation:
Given is the graph bell shaped.
We have to find the variance of the data
We see that the graph looks like a normal distribution curve symmetrical about x=19
Hence mean =19
Since we know maximum area covered within 3 std deviations on either side of mean, we can calculate 6 sigma value from the graph
Extreme left x value = 14 and right = 24
Hence 6 times std dev =24-14 =10
So std deviation = 10/6 =5/3
Variance = 25/9
The answer to this question is 5 days
As this is a parallelogram c=e
so 9y=7y+28
9y-7y=28
2y=28
y=14
so e would be 7(14)+28
=98+28
=126.
and as d + e =180, d=180-126
d=54
and as CF=DE
2x=x+5
2x-x=5
x=5
CF=2x
=2(5)
=10
and lastly CD=FE
CD=3x-4
CD=3(5)-4
=15-4
=11
FE=11
so the answers are:
FE=11
CF=10
d=54
e=126.
hope this helps
Answer:
4-12X
Step-by-step explanation:
Expression: (x+2)-(1x-2)-12x
First step: x+2-1x+2-12x
Second step: (2+2)+(x-1x-12x)
Third step: 4-12X
Answer:
A= P(1+r)^x
$2025
Step-by-step explanation:
Given data
Principal= $1000
Rate= 4%
1. - Develop a function to show the amount in the savings account after x years
Time= x years
The function is
A= P(1+r)^x
2. How much money will be in the account when Theo is 18 and ready for college?
Time= 18 years
A= 1000(1+0.04)^18
A=1000(1.04)^18
A=1000*2.025
A=$2025
