A game at a county fair has a spinning drum holding 15 colored plastic balls: some white, some green, and some red. Every time t

he drum spins, one ball drops out, its color is recorded, and then the ball is placed back in the drum. The table shows the results after 15, 150, and 1500 spins.
What is the best estimate of the number of white balls in the drum?

Outcome Number of trials
15 150 1500
white 5 61 680
green 9 74 713
red 1 15 107

The measure of ∠ROU is 94°.  That is a central angle, which means that the arc it intercepts also measures 94°.  Because ∠SOT is vertical to ∠ROU it is also a 94° angle with a 94° intercepted arc.  The other 2 angles, ∠SOR and ∠TOU are vertical and have the same measure, both the angles and their intercepted arcs.  Those measures will split the difference of 360-94-94, which is 172.  172/2 is 86.  That means that those arcs also measure 86.  Arc SRT is the addition of arc SR, RU. and UT, which are 86+94+86, respectively, which add up to 266.  Second choice down.

The point-slope form of the equation for a line can be written as

... y = m(x -h) +k . . . . . . . for a line with slope m through point (h, k)

Your function gives

... f'(h) = m

... f(h) = k

a) The tangent line is then

... y = 5(x -2) +3

b) The normal line will have a slope that is the negative reciprocal of that of the tangent line.

... y = (-1/5)(x -2) +3

_____

You asked for "an equation." That's what is provided above. Each can be rearranged to whatever form you like.

In standard form, the tangent line's equation is 5x -y = 7. The normal line's equation is x +5y = 17.

Theresa has two brothers, Paul and Steve, who are both the same height. Paul says he is
Schach [20]

Answer:

From given, we have,

Paul says he is 16 inches shorter than 1 1/2 times Theresa's height.  

Steve says he's 6 inches shorter than 1 1/3 times Theresa's height.

Let the height of Theresa be "x" inches.

So, we get,

For Paul, 1 1/2 x - 16 = T

⇒ 3/2 x - 16 = T ......(1)

For Steve, 1 1/3 x - 6 = T

⇒ 4/3 x - 6 = T .........(2)

equating  equations (1) and (2), we get,

3/2 x - 16 =  4/3 x - 6

6 - 16 = 4/3 x - 3/2 x

-10 = (8 - 9)/6 x

-60 = -x

x = 60 inches.

Therefore, Theresa is 60 inches tall.

hamburgers cost $2 per lbs and chicken costs $3 lbs and you only have $30 to spend and expect At least 3lbs of hamburger​
kicyunya [14]

If you want at least 3 pounds of hamburgers, then $6 is enough to buy those 3 pounds of hamburgers. If you ONLY buy 3 Pounds, then you also have enough for 4 pounds of chicken. $3 a pound x 4 = $12. You have 2 dollars left to spare, which means you can buy another pound of hamburgers. So 4 pounds each are able to be purchased.
