The formula to calculate the experimental probability is "P(event) = Number of times event occurs/total number of trials"

The expiramental probability should be the fraction "21/47"

The theoretical probability should be the fraction "1/3" because the formula for theoretical probability is the number of favorable outcomes (5 dollar bill) over the total number of possible outcomes (10-dollar bill, one dollar bill, & 5 dollar bill). therefore, there is 1 favorable outcome, and 3 possible outcomes = 1/3.

Can someone help me with these please.
ELEN [110]

Answer: Barbara did not include a variable in the term 1.49, which must represents the number of bottles of iced tea she needs to sell.

Step-by-step explanation:

Let be "x" the number of bottle of water Barbara needs to sell and "y"  the number of bottle of iced tea she needs to sell.

She sells iced tea for $1.49 per bottle and water for $1.25 per bottle, so she can write the following equation in order to calculate the number of bottles she needs to sell to earn $100:

1.25x + 1.49y = 100

Since Barbara wrote this equation:

1.25x + 1.49 = 100

We can conclude that the error Barbara made in writing the equation was: She did not include a variable in the term 1.49, which must represents the number of bottles of iced tea she needs to sell.

Which equation represents the line that passes through the point (4, -5) and is perpendicular to the line x + 2y = 5?
Lerok [7]

Answer:

y = 2x - 13

Step-by-step explanation:

Equation of a line is y = mx + c, m is the gradient and c is the intercept

The line passes through points 4 and -5, x is 4 and y is -5

-5 = 4m + c

When two lines are perpendicular, the products of their gradients are equal to -1, m1 * m2 = -1

x + 2y = 5

2y = -x + 5

y = (-1/2 * x) + 5

therefore m = -1/2

m1 * m2 = -1

m * -1/2 = -1

-m = -2 , therefore m = 2

-5 = 4 * 2 + c

c = -5 - 8, which is -13

Therefore the equation for the line is

y = 2x - 13

What is the derivative of this
skelet666 [1.2K]
\bf r(x)=\cfrac{3x-2}{2x+5}\implies \cfrac{dr}{dx}=\stackrel{quotient~rule}{\cfrac{3(2x+5)~~-~~(3x-2)2}{(2x+5)^2}}
\\\\\\
\cfrac{dr}{dx}=\cfrac{\underline{6x}+15\underline{-6x}+4}{(2x+5)^2}\implies \cfrac{dr}{dx}=\cfrac{19}{(2x+5)^2}
