Answer:
A
Step-by-step explanation:
In converting a decimal to a percent you just need to multiply it by 100.
Solution on the problem above:
3.45 x 100 = 345%
Therefore the answer is letter A.
It will be vice versa in converting percent to decimal. You just need to divide it by 100.
For example, we convert the 345% to decimal:
345%/100 = 3.45
Answer:
The correct answer is C
Step-by-step explanation:
If we see a curved relationship in the residual plot, the linear model is not appropriate. Another type of residual plot shows the residuals versus the explanatory variable.
Answer:
The probability of getting an odd number when the spinner is spun, is p(even number) = 1/2
Step-by-step explanation:
Given that the spinner has 12 equal sections labelled 1-12
Let S be the sample space
Then
S = {1,2,3,4,5,6,7,8,9,10,11,12}
Let A be the event that the outcome is an even number
Then
A = {2,4,6,8,10,12}
The probability of A will be given as:
Hence,
The probability of getting an odd number when the spinner is spun, is p(even number) = 1/2
Answer:
Step-by-step explanation:
b and c are the speeds of the boat in stool water, and current, respectively.
Going with the current, the boat travels b+c=16 km/h.
Going against the current, the boat travels b-c=6 km/h
add the equations together
b+c = 16
b-c = 6
—————
2b = 22
b = 11
c = 16-b = 5
