First calculate your surface area and volume, then make a ratio: SA=5x5x6=150u²,
V=5x5x5=125u³;
Ratio: 150/125=6/5
Answer: 271
Step-by-step explanation:
The formula we use to find the sample size is given by :-
, where is the two-tailed z-value for significance level of
p = prior estimation of the proportion
E = Margin of error.
If prior estimation of the proportion is unknown, then we take p= 0.5 , the formula becomes
Given : Margin of error : E= 0.05
Confidence level = 90%
Significance level
Using z-value table , Two-tailed z-value for significance level of
Then, the required sample size would be :
Simplify,
Hence, the required minimum sample size =271
Answer:
angle C,D,A
Step-by-step explanation:
isnt it just finding a right angle?
Answer:
Step-by-step explanation:
Let L represent the number of laptops and B represent the number of Bicycles.
We are told that each laptop is worth $200, so price of L laptops will be 200L.
We are also told that each bicycle that Hyun Yong donates is worth $100, so B bicycles will be worth 100B dollars.
We are told that Hyun Yong wants to donate more than$5000 in laptops and bicycles. This means that total cost of L laptops and B bicycles should be greater than 5000.
We can represent this information in an inequality as:
Therefore, the inequality represents the number of laptops (L) and bicycles (B) that Hyun Yong should donate to achieve his goal.
You can plug in any values that make the equation true, and then plot the ordered pair.
I chose (3,1) and (6,4)
1 = 3-2
4=6-2
Plot the two ordered pairs and connect the dots to draw a line.
