disa [49]

The answer is:  "6.75 ft." .
______________________________________________
Explanation:
_____________________________________________
2 / 3 = (4.5) / x ; Solve for "x" ;

     2x = (3)(4.5) ;

Divide each side of the equation by "2" ; to isolate "x" on one side of the equation; and to solve for "x" ;
_________________________________________________
    2x / 2 = [3*(4.5)] / 2 ;

    to get: x = (13.5)/2 = 6.75 ft. This is already rounded to the
                                                       nearest hundredth.

Which graph represents y=3 sqrt x+2

ziro4ka [17]

Answer:

The graph in the attached figure

Step-by-step explanation:

we have

$y=3\sqrt{x+2}$

Remember that the radicand must be greater than or equal to zero

$x+2\geq 0$

solve for x

subtract 2 both sides

$x\geq -2$

The domain is the interval [-2,∞)

All real number greater than or equal to -2

For x=-2

$y=3\sqrt{-2+2}=0$

The range is the interval [0,∞)

All real number greater than or equal to 0

Find the y-intercept

Remember that the y-intercept is the value of y when the value of x is equal to zero

For x=0

$y=3\sqrt{0+2}$

$y=3\sqrt{2}$

$y=4.243$

The y-intercept is the point (0,4.243)

therefore

The graph in the attached figure

Answer:

The probability that in a one-game playoff, her score is more than 227 is 0.4404.

Step-by-step explanation:

We are given that Susan has been on a bowling team for 14 years. After examining all of her scores over that period of time, she finds that they follow a normal distribution. Her average score is 225, with a standard deviation of 13.

Let, X = scores over that period of time

X ~ N( $\mu = 225, \sigma = 13^{2}$ )
