ANSWER: FG = 69
FG = FK + KG
KG = 1/2(FK)
FK = 46
RULE: When it comes to centroids, the longer section of the line is always 2/3 of the entire line (+ the shorter section of the line is always 1/3). This means that the shorter section of the line is HALF of the longer section of the line.
FG = FK + KG
FG = 46 + 46/2
FG = 46 + 23
FG = 69
CHECK:
FK = 2/3(FG)
46 = 2*69/3
46 = 138/3
46 = 46 ✔️
or
KG = 1/3(FG)
1/2(FK) = 1/3(FG)
46/2 = 69/3
23 = 23 ✔️
Answer: 9 meters
Step-by-step explanation:
Hi, to answer this question we have to apply the formula:
Surface area if a cylinder (S)= 2 π r2 + 2 π r h
Where r is the radius and h is the height
Diameter is equal to 2r , so in our case:
14 =2r
r = 14/2 = 7 meters
Replacing with the values given and solving for h:
224 pi = 2 π 7^2 + 2 π 7 h
224 π - 2 π 7^2 / 2 π 7= h
703.71 -307.87 /43.98 = h
9 = h
Answer:
400 guitars
Step-by-step explanation:
200+200=400
Answer:
a = -14
Step-by-step explanation:
a-2/3=-4. Multiply -4 by 3 to get rid of the denominator. This leaves you with a-2 = -12. Move the -2 to the other side to get a = -2-12, which simplifies to a = -14.
Answer:
The probability that the mean is less than 110
P(x⁻<110) =0.5
Step-by-step explanation:
<u>Explanation</u>:-
Given the standard deviation of the Population' σ' = 1250
Given sample size 'n' = 350
The standard error of the mean determined by
Standard error = 
by using normal distribution 
cross multiplication 66.8z = x⁻-110
x⁻ = 66.81Z+110
P(x⁻<110)=P(66.81Z+110<110)
= P(66.81Z < 110-110)
= P(66.81Z<0)
= P(Z<0)
= 0.5- A(z₁)
= 0.5 - A(0) (here z₁=0)
= 0.5 -0.00
=0.5
<u>Conclusion:- </u>
The probability that the mean is less than 110
P(x⁻<110) =0.5
