1 1/6 * 9

____________________________________________________________

Change 1 \frac{1}{6} to an improper fraction.

Multiply the whole number by the denominator and add the numerator. Your answer will become the numerator and the denominator stays the same.

\frac{(1 \times 6 + 1)}{6} → 7/6

____________________________________________________________

Make 9 an improper fraction by adding 1 to its denominator (doesn't change its value)

9 → 9/1

____________________________________________________________

Multiply 7/6 * 9/1

\frac{7}{6} \times \frac{9}{1}

Multiply top and bottom numbers

This would look like: \frac{7 \times 9}{6 \times 1}

\frac{7 \times 9}{6 \times 1} = \frac{63}{6}

____________________________________________________________

Answers:

Improper fraction: \boxed {\frac{63}{6} }

Mixed number: \boxed {10 \frac{1}{2} }

Find the surface area of the pyramid shown to
Butoxors [25]

Answer:

914 m^2 to the nearest whole number.

Step-by-step explanation:

The area of the hexagonal base is made up of 6 congruent triangles so its area = 6 *  1/2 base * height

= 6 * 1/2 * 12 * 6√3

= 216√3 m^2.

The area of each slanting triangle = 6 * 15 m^2 so the lateral area of the pyramid

= 6*6*15 = 540 m^2

Total surface area = 540 + 216√3

= 914.12 m^2.

For a bivariate random variable (x, y ), if the covariance is 1225, the variance of x is 1600, and the variance of y is 2500. Fi
prisoha [69]

If the covariance is 1225, variance of x is 1600,variance of y is 2500 then the correlation coefficient between x and y is 0.6125.

Given the covariance is 1225, variance of x is 1600,variance of y is 2500.

We have to find the correlation coefficient between x and y.

Covariance is basically a measure of the joint variability of two random variables.

Variance is a basically a measure of dispersion, meaning it is a measure of how far a set of numbers is spread out from their average value.

The correlation coefficient is basically the specific measure that quantifies the strength of the linear relationship between two variables in a correlation analysis.

We know that the formula of correlation coefficient is as under:

r=covariance (x,y)/\sqrt{variance(x)}*\sqrt{variance (y)}

r=1225/\sqrt{1600}*\sqrt{2500}

r=1225/(40*50)

r=1225/2000

r=0.6125

Hence if the covariance is 1225, variance of x is 1600,variance of y is 2500 then the correlation coefficient between x and y is 0.6125.
