Answer:
Length of each piece = 16cm.
Step-by-step explanation:
Since the chart paper is 48cm x 32cm in size, finding the total area of the paper would be A = l x w, where l=length of the paper and w=width.
A = 48 x 32 = 1536cm²
Since Stitu was able to get 6 equal pieces, then we can take the total area and divede by 6:
Since 256cm² represents the area of each square, we can take the square root of this number to find the length of just one square since the formula for the area of a square is A=s², where s=the length of one side:
s² = 256 so √s² = √256 or s = 16cm
Answer:
where is the graph?
Step-by-step explanation:
An hour is 60 minutes.
60 minutes/ 15 minutes = 4
There are 4 15 minute segments in an hour.
1 quart x 4 = 4 quarts per hour.
Answer:
A recipe for 1 pizza crust calls for 3/8 table spoon
therefore,
3 pizza crust calls =3/8 × 3=9/8=1.13
tablespoon .
Step-by-step explanation:
Given Information:
Population proportion = p = 0.55
Sample size 1 = n₁ = 30
Sample size 2 = n₂ = 100
Sample size 3 = n₃ = 1000
Required Information:
Standard error = σ = ?
Answer:
Step-by-step explanation:
The standard error for sample proportions from a population is given by
Where p is the population proportion and n is the sample size.
For sample size n₁ = 30
For sample size n₂ = 100
For sample size n₃ = 1000
As you can notice, the standard error decreases as the sample size increases.
Therefore, the greater the sample size lesser will be the standard error.
