Answer:
7 fancy shirts and 5 plain shirts
Step-by-step explanation:
f and p are the numbers of fancy and plain shirts
f+p = 12
p = 12-f
20f + 10p = 190
20f + 10(12-f) = 190
20f + 120 - 10f = 190
10f = 70
f = 7
p = 12-f = 5
Answer: 13.6
Step-by-step explanation:
subtract the lowest number from the highest number to find the range. in this case, the data range is 25.6−12=13.6
Solution:
Number of babies which are female = 50%=
So, if Population of 50 is considered , and 50% of population is female then out of 25 must be female.
Population of female can't exceed 25.
Probability of an event =
Probability that 20 or more of the 50 babies born today were female
=
Simulation of the Above Situation
If we use a double sided coin and a sign heads us females and Tails as males,Toss the coin 50 times , number of times Heads comes shows number of females born and number of times tails appears shows Population of men.
It may not happen that Number of heads =Number of tails if we toss the coin 50 times.So if number of tosses increases the chances are more likely that , number of heads= Number of tails. But for above problem we just have to toss coin 50 times only, that is
Number of males = Number of females
Hi again!
Your answer is D. 5/42. Here's how we got that.
1) Multiply across. 1 * 5 / 6 * 7.
2) 1 * 5 = 5. 6 * 7 = 42.
Put solved form of 1 * 5 and 6 * 7 into fraction.
5 / 42.
Hope this helps! ☺♥
