The maximum number of batches in the table is 9
So, 6 more batches than the maximum number of batches is 9+6=15
Also, we must see that there is a trend in the total number of cookies
As the batch increases by one, we can see that the total number of cookies increases by 16
Hence, the total number of cookies when she bakes 15 batches is
229+ 15x6 = 319

How do you take 79-100 and then do what ever that = and turn that into a fraction

Alekssandra [29.7K]

79 $\frac{79-100}{1} = \frac{-21}{1} = \boxed {\frac{-21\times x}{1\times x}= \frac{-21}{1} = \frac{-42}{2}= \frac{-63}{3} =... and~so ~on}$

What do I need to do here? I don't understand.

Allushta [10]

All you have to do to solve this is to find the square root of 183.84 and multiply it by 4. Since the square root is 13.558761005342634 then that would equal one side of the square. Multiply it by 4 to get the perimeter of the entire square.

A bakery sells rolls in units of a dozen. The demand X (in 1000 units) for rolls has a gamma distribution with parameters α = 3,

bearhunter [10]

Answer:

The value is $E(X) = \$ 1.7067$

Step-by-step explanation:

From the question we are told that

The parameters are α = 3, θ = 0.5

The cost of making a unit on the first day is c = $2

The selling price of a unit on the first day is s = $5

The selling price of a leftover unit on the second day is v = $ 1

Generally the profit of a unit on the first day is

$p_1 = 5 - 2$

$p_1 = \$3$

The profit of a unit on the second day is

$p_2 = 1 - 2$

=> $p_2 = - \$1$

Generally the probability of making profit greater than $ 1 is mathematically represented as

$P(X > 1 ) = Gamma (X ,\alpha , \theta)$

=> $P(X > 1 ) = Gamma (1 ,3 , 0.5)$

Now from the gamma distribution table we have that

$P(X > 1 ) = 0.67668$

Generally the probability of making profit less than or equal to $ 1 is mathematically represented as

$P(X \le 1 ) = 1 - P(X > 1 )$

=> $P(X \le 1 ) = 1 - 0.67668$

=> $P(X \le 1 ) = 0.32332$

So the probability of making $3 is $P(X > 1 ) = 0.67668$

and the probability of making -$1 is $P(X \le 1 ) = 0.32332$

Generally the value of profit per day is mathematically represented as

$E(X) = 3 * P(X > 1 ) + (-1 * P(X \le 1 ) )$

=> $E(X) = 3 * 0.67668 + (-1 * 0.32332 )$

=> $E(X) = \$ 1.7067$

What is the equation of the line that is parallel to the line y =-1\3

PilotLPTM [1.2K]

Hello!

If a you want to find an equation of the line that is parallel to the given line, we must know that if two lines are parallel, then their slope will <em>always</em> have to be equal.

This means that the new equation must have a slope of -1/3.

Also, you would need to substitute the given point (6, 8) into the equation with the slope: -1/3 as well. Following these steps allows you to find the equation of line.

y = -1/3x + b (6, 5)

5 = -1/3(6) + b

5 = -2 + b (add 2 to both sides)

7 = b

Therefore, the equation of the line is y = -1/3x + 7.
