Answer:
1.4
Step-by-step explanation:
use distance formula
Answer:
E) 166
Step-by-step explanation:
Standard deviation is 10
Margin error for the problem is 2
Probability 99%, that means thet the siginficance level α is 1 – p
α = 1 – 0.99 = 0.01
margin of error (ME) can be defined as follows
ME = Z(α/2) * standard deviation/ √n
Where n is the sample size
Z(0.01/2) = Z(0.005)
Using a z table Z = 2.576
Now, replacing in the equation and find n
2 = 2.576 * 10/ √n
2 = 25.76 /√n
√n = 25.76 /2
√n = 12.88
n = 12.88^2
n = 165.89 ≈166
Answer:
28
Step-by-step explanation:
700 x 4% = 700 x 0.04 = 28
Answer:
10
Step-by-step explanation:
Since it's a right angle, it's already 90 degrees. So, you add 48 + 32 which gives you 80. 80 minus 90 equals 10.
48 + 32 = 80
90 - 80 = 10
