Answer:
1240 (I'm not so sure but per my calculation that is what i got)
Step-by-step explanation:
Boy : Girl
11 : 9
124 + x : x
11/9 = 124 + x / x
9(124 + x) = 11 x
1116 + 9x = 11x
1116 = 11x - 9x
1116 = 2x
x = 558
Thus, there are 558 girls in the school
Number of boys = 124 + x
= 124 + 558
= 682
Therefore, total number of students = 558 + 682 = 1240 students
Answer:
1. 6
2. 1
3. 5
Step-by-step explanation:
You can find the GCF by finding the prime factorization of the numbers.
1. 12 and 18
12= 2*2*3
18=2*3*3
They both have 2 and 3 in common, so their GCF is 2*3 or 6.
2. 9 and 35
9= 3*3
35= 5*7
Although they don't have any prime numbers in common, all numbers have the factor one in common, so they're relatively prime but their GCF is 1.
3. 15 and 25
15 = 3*5
25= 5*5
They have one 5 in common so their GCF is 5.
A 95% confidence interval for the proportion of non-fatal accidents involving a distracted driver using some kind of electronic device is 62.5%<x<71.61%
The 95% confidence interval for the proportion is expressed according to the formula;
p is the proportion = 268/400 = 0.67
z is the 95% z-score = 1.96
n is the sample space = 400
Substitute the given parameters into the formula to have:
Hence a 95% confidence interval for the proportion of non-fatal accidents involving a distracted driver using some kind of electronic device is 62.5%<x<71.61%

Well its actually really easy :) I am a girl lol
Step-by-step explanation:
We like it when you just talk and be there for us. Make jokes get to know the girl and just talk to her. A real relationship will take time for the connection to grow if you want a good long relationship don't rush to get into it with the person.
