Answer:
16.68 cm
Step-by-step explanation:
Given that :
Mean , m = 15
Standard deviation, s = 2
Length of salamander that would Place it at 80% of salamander length :
P(Z ≤ x) = 0.8
Zscore equivalent to 0.8 = 0.842
Using the relation :
Zscore = (x - m) /s
0.842 = (x - 15) / 2
1.684 = x - 15
Add 15 to both sides
1.684 + 15 = x - 15 + 15
16.684 = x
Hence, x = 16.68 cm
Negative , you always put the biggest numbers value at the end
Answer:
5 nickles in a quator.
Step-by-step explanation:
We start with 56/154. Dividing each number by two, we have:
28/77
Dividing each number by seven, we have:
4/11
As the greatest common factor of 4 and 11 is 1, this fraction is in simplest form. Thus, 56/154 is equal to 4/11.
Answer:
a = 72
Step-by-step explanation:
Subtract 56 from both sides of the equation so you can isolate the variable
128-56=72
