Answer:
53/5 = 10 3/5
Step-by-step explanation:
convert both to fraction
7x5 + 1 = 36
3x5 + 2 = 17
36 + 17 = 53
actually you could have just added
7 + 3 = 10
1 + 2 = 3 for the fraction
Answer:
She can buy 8 bags of soil
Step-by-step explanation:
2.7s + 14.9 < 39.2
Subtract 14.9 from both sides
2.7s < 39.2 - 14.9
2.7s < 24.3
Divide both sides by 2.7
s < 24.3 /2.7
s < 8.89

Answer: = ( 0.411, 0.409)
Therefore at 95% confidence interval (a,b) = (0.411, 0.409)
Step-by-step explanation:
Confidence interval can be defined as a range of values so defined that there is a specified probability that the value of a parameter lies within it.
The confidence interval of a statistical data can be written as.
x+/-zr/√n
Given that;
Mean gain x = 0.41
Standard deviation r = 0.016
Number of samples n = 1000
Confidence interval = 95%
z(at 95% confidence) = 1.96
Substituting the values we have;
0.41+/-1.96(0.016/√1000)
0.41+/-1.96(0.000506)
0.41+/-0.00099
0.41+/-0.001
= ( 0.411, 0.409)
Therefore at 95% confidence interval (a,b) = (0.411, 0.409)
