Lst question: x = 5, y = 7
2nd question: x = -1, y = 5
3rd question: x = 98, y = 80
Te difference of 2 standard deviation of a population n1 & n2 is given by the formula:
sigma (difference)=√(sigma1/n1 + sigma2/n2), Plug:
sigma(d)= √(49/100 + 36/50)
Sigma(d=difference) =1.1
Answer:
0.43
Step-by-step explanation:
Yellow flowers are 43%.
White flowers are = (100% - 43% ) = 57%
Consider there are total 100 flowers in the garden , so yellow ones are 43 and white ones are 57
Probability of a bee landing on a yellow flower is 43 out of 100
= 43/ 100
=0.43
