The table below shows the survey results for six randomly selected lions from five different zoos.

blsea [12.9K]

Answer:

Correct option: fourth one

Step-by-step explanation:

We can see in the table that we have three variables: the gender of the lion, the number of offspring and the age in years.

From these three variables, the gender is a categorical variable, because it can only assume a finite number of values (in this case, 2 values: M or F)

The other two variables (no. of offspring and age) can theoretically assume an infinite number of values (any non-negative integer number).

So the correct option is the fourth one: three variables, and one of them is categorical.

write the slope intercept form of the equation of the line with a slope of -2/5 that passes through 15, -9/2

Sever21 [200]

Answer:

The equation of line in slop-intercept form is y = $\dfrac{-2x}{5}$ + $\dfrac{3}{2}$

Step-by-step explanation:

Given as :

The slope of the a line = m = $\dfrac{-2}{5}$

The line is passes through points $x_1 , y_1$ = 15 , $\dfrac{- 9}{2}$

<u>According to question</u>

Equation of line in slope - intercept form

y - $y_1$ = m × ( x - $x_1$ )

Or, y - ( $\dfrac{- 9}{2}$ ) = $\dfrac{-2}{5}$ × ( x - 15 )

Or, y - ( $\dfrac{- 9}{2}$ ) = $\dfrac{-2}{5}$ × x - ( $\dfrac{-2}{5}$ ) × 15

Or, y - ( $\dfrac{- 9}{2}$ ) = $\dfrac{-2}{5}$ × x + 6

Or, y = $\dfrac{-2}{5}$ × x + 6 - $\dfrac{9}{2}$

Or, y = $\dfrac{-2}{5}$ × x + $\dfrac{12-9}{2}$

Or, y = $\dfrac{-2}{5}$ × x + $\dfrac{3}{2}$

So, The equation of line in slop-intercept form y = $\dfrac{-2}{5}$ × x + $\dfrac{3}{2}$

Hence, The equation of line in slop-intercept form is y = $\dfrac{-2x}{5}$ + $\dfrac{3}{2}$ Answer

Find the quotient of 812.30 divided by 83. Round to the nearest tenth.

elena-14-01-66 [18.8K]

812.30/83 = 9.78674698.....
Nearest tenth means one number under decimal place so...

812.30/83 ~ 9.8

Explanation: The 9.7... rounded up to 9.8 because the number after the tenths place (in this case the number after the 7) is greater or equal to 5.
