Their answer is correct so you need explanation?
Answer:
Sample size should be less than 85
Step-by-step explanation:
Sample size should be less than 85
Step-by-step explanation:
To use the infinite standard deviation formula, n has to be <= (0.05)(1700)
n <= 85
So the sample size has to be less than 85
In another way too,
n = sample size
N = population size
For population, we multiply correction factor to the infinite standard deviation
F is <= 0.05
n<0.05x1700
n<85
Sample size should be less than 85
Answer:
y = 6x + 24
Step-by-step explanation:
Remember, any line can be parallel to y= 6x + 8 as long as it has the same slope (m, or in this case 6), and a different b (in this case 8).
Answer:
x = -1
Step-by-step explanation:
4(x - 7) + 8(1 - 6x) = 24
distribute
4x - 28 +8 -48x = 24
Combine like terms
-44x -20 = 24
Add 20 to each side
-44x -20+20 = 24+20
-44x = 44
Divide each side by -44
-44x/-44 = 44/-44
x = -1
Complete question :
Jenna’s method: Mia’s method: 5(30 + 4) 5(30 + 4) (5)(30) + (5)(4) 5(34) = 170 150 + 20 = 170 Explain why both Jenna and Mia arrived at the same answer and the advantage of one method over the other.
Answer:
Kindly check explanation
Step-by-step explanation:
Jenna's method :
5(30 + 4) = 5(34) = 170
Mia’s method :
5(30 + 4) :
5(30) + 5(4)
150 + 20
= 170
With both methods, we will arrive at the same answer as justified in the workings above. However, Jenna's method gives a very simple approach and less complicated arithmetic by using the distributive property to overrode some multiplication process which Mia went through in her own calculation. Therefore, Jenna's method is less complicated and requires two simple steps at obtaining the final result.
