The ratio of males to females is 1.4 : 1, so the fraction of the total that is made up of males is 1.4/(1.4 + 1) = 1.4/2.4 = 7/12.
There were (7/12)*475 ≈ 277 males at the party.
There were 475 - 277 = 198 females at the party.
Answer:
140.37 in²
Step-by-step explanation:
C = 2πr
42 = 2πr
21 = πr
r = 21/π
A = πr²
A = π × (21/π)²
≈ 140.37 in²
Answer:
the statements given above are true.
Step-by-step explanation:
Given that Frederick designed an experiment in which he spun a spinner 20 times and recorded the results of each spin.
He spun a 4 five times.
The statements true are:
i) For the experimental outcomes to be closer to the predicted outcome, the number of trials should be increased.
iii) If the number of trials is changed, the experimental probability also changes.
iv) If the number of trials is changed, the predicted number of outcomes also changes.
v) If the number of trials is changed, the number of experimental outcomes also changes.
