Answer = 48 blue counters
———————————————
There are originally 18 red and 48 blue.
The ratio of 3:8 is multiplied by six
3 x 6 = 18
8 x 6 = 48
Take out two red
18 - 2 = 16
The ratio 16:48 (divide by 3) simplifies to 1:3
so it fits.
Answer:
25/64
Step-by-step explanation:
To get this answer, first you need to use the distributive property:
(-3/8)(-5/8) - (1/4)(-5/8)
Next, multiply:
15/64 - (-5/32)
Change the negative signs into a positive sign:
15/64 + 5/32
Multiply 5/32 by 2 on both top and bottom:
15/64 + (5)(2)/(32)(2)
You will then get:
15/64 + 10/64
Now, add the numerators. You will get:
25/64

Answer:
1. C
2. B
3. $220
4. $100
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.
