The given expression can be proved using the Pythagorean identity as shown below:

$L.H.S \\ \\ 
= 1+ sec^{2} *sin^{2}x \\ \\ 
=1+ \frac{1}{cos^{2}x } sin^{2}x \\ \\
=1+tan^{2}x \\ \\ 
=sec^{2}x \\ \\ 
= R.H.S 
$

Thus, the Left hand side has been proved equal to Right Hand Side.

I don’t know how to solve this problem

The draws are independent, so

$P(\text{red then blue})=P(\text{red})\cdot P(\text{blue})$

There is a total of 11 marbles in the bag, so

$P(\text{red})=\dfrac3{11}$

and

$P(\text{blue})=\dfrac5{11}$

$P(\text{red then blue})=\dfrac{15}{121}$

Ainat [17]

Determine the level of measurement of the variable below.assessed value of a house?

Solution: Assessed value of a house is a ratio variable, because assessed value of a house can be measured numerically and difference between any two values has a useful meaning. Also, when the assessed value of a house is zero, it means there is none of this variable. Therefore, the assessed value of a house is a Ratio Variable
