The marginal loss on Washington reds, a brand of apples from the state of Washington, is $35 per case. The marginal profit is $1
AlexFokin [52]

Answer:

42666 cases

Step-by-step explanation:

P = (Marginal Loss)/ (Marginal Loss + Marginal Profit)

P = (35)/(35+15) = 0.7

Considering a normal distribution we can find the corresponding z value by P = 0.7 (which represented the shaded area under the curve)

z = 0.5244

z = (X - Mean Sales)/Standard Deviation

-0.5244 = (X - 45000)/4450

X = 42666.42 ≅  42666

Which of the following is a solution of the system
Aleks [24]

Answer:

Answer B

Step-by-step explanation:

1.  (1, -4) is NOT a solution because (1) - 2(-4) < 4 is false.

2.  (-8, 2):  -8 - 2(2) < 4 is true, and in simplified form is -12 < 4 (true)  We must check whether this point (-8, 2) ALSO satisfies y > -2x - 5:

2 > -2(-8) - 5.  Yes, this is true, so the given point satisfies both inequalities in Answer B.

Jack wants to plant a border of flowers in the shape of an arc along the edge of a circular walkway. of the circle has a radius
Jet001 [13]
To solve this problem you must apply the proccedure shown below:

 1. You must apply the formula for calculate the arc length, which is:

 arc length=(angle)(radius)

 2- As you can see, <span>the circle has a radius of 5 yards and the angle subtended by the arc measures 1 1/2 radians. Therefore, you have:
</span>
 The angle is:

 1 1/2 radians=1.5 radians

 3. When you susbtitute these values into the formula, you obtain:

 arc length=(1.5 radians)(5 yards)
 arc lenght=7.5 yards

 4. Therefore, the answer is: 7.5 yards.

Answer:

The literals are; a, b, and c

The constants are; c, and 3

The variables are; x, and y

Step-by-step explanation:

The literals (numbers) are letters which represent numbers in an expression or equation, and to which mathematical operations, including, addition, subtraction, division, and multiplication can be applied

The given equation is a·x² + b·x + c - y + 3 = 0

The literals are;

'a', 'b', and 'c'

The constants are the values that remain the same always in an equation and does not change

The constants are;

'c', and '3'

The variables are the values that vary in relation to one another

The variables are;

'x', and 'y'
