That would be 43 divided by 23 which would equal 1.8695
There is 60% of red t-shirts 40% of them are white and blue so the reds are 60%
Answer:
that no. is 20
Step-by-step explanation:
let us take that certain no. as x
so
2/5. x +2=10
2x/5 = 10-2
2x = 8×5
x= 40/2
x= 20
4 is the answer because it’s just common sense
Answer:
0.12 ± 1.96 * √(0.12(0.88) / 100)
Step-by-step explanation:
Confidence interval :
Phat ± Zcritical * √(phat(1 -phat) / n)
Phat = 12/100 = 0.12
1 - phat = 0.88
Zcritical at 95% = 1.96
Hence, we have :
0.12 ± 1.96 * √(0.12(0.88) / 100)
0.12 ± 1.96 * 0.0324961
0.12 ± 0.0636924
Lower boundary = (0.12 - 0.0636924) = 0.0563
Upper boundary = 0.12 + 0.0636924 = 0.1837
