Let, the Age of Michelle = x
Age of Steve = x + 15

After 8 years, (x + 15 + 8) = 2(x + 8)
x + 23 = 2x + 16
2x - x = 23 - 16
x = 7
So, x + 15 = 22

In short, Age of Michelle is 7 & Age of Steve is 22 Years

Hope this helps!

Which is bigger 3/8 or 0.3
Luba_88 [7]
\frac{3}{8} \\
0.3=\frac{3}{10}

If two fractions have the same numerator, the fraction with the smaller denominator is bigger.
8\ \textless \ 10 \Rightarrow \frac{3}{8} \ \textgreater \  \frac{3}{10}

3/8 is bigger.

svetoff [14.1K]

Answer:

= ( -4.725, 6.945) pg/ml

Therefore at 95% confidence interval (a,b) = ( -4.725, 6.945) pg/ml

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 = 1.11 pg/ml

Standard deviation r = 15.18 pg/ml

Number of samples n = 26

Confidence interval = 95%

z(at 95% confidence) = 1.96

Substituting the values we have;

1.11+/-1.96(15.18/√26)

1.11+/-1.96(2.977042931397)

1.11+/-5.835004145539

1.11+/-5.835

= ( -4.725, 6.945) pg/ml

Therefore at 95% confidence interval (a,b) = ( -4.725, 6.945) pg/ml
