Answer:

(8, 23, 31)

Step-by-step explanation:

The sum of the lengths of the two shorter legs must be greater than the length of the longer leg

(not equal to either)

Use the inverse sine ratio when you know the length of a leg opposite the required angle. True or false

Answer:

False

Step-by-step explanation:

The function you use to find the angle will depend on the other information given. Regardless, finding the angle may involve the inverse sine function, not the inverse sine ratio.

_____

If you know the leg adjacent as well as the leg opposite, the inverse tangent function will be an appropriate choice.

The probability that an individual is left-handed is 0.12. in a class of 39 students, what is the probability of finding five le

Snezhnost [94]

We are given:

p = probability = 0.12
n = total students = 39

x = left handers = 5
u = mean = p* n = 4.68
σ = standard dev = √ ( n*p*(1-p)) = √ ( 39 * 0.12 * 0.88 ) = 2.03

Calculating for the z score:

z = (x – u) / σ
z = (5 – 4.68) / 2.03

z = 0.1576 = 0.16

Using the standard tables for z, the p value is:

p value = 0.5636 = 56.36%

Hence there is a 56.36% chance.

A farmer has 20 acres to plant in wheat and barley. He has to plant at least 15 acres. Wheat costs $200 per acre to plant and ba

maria [59]

Answer:

16 acres of barley only (no acres of wheat)

Step-by-step explanation:

A graph shows cost of planting puts an upper limit on planted area. The lower limit is provided by the requirement to plant at least 15 acres. The vertices of the feasible solution region are ...

(wheat acres, barley acres) = {(0, 15), (0, 16), (3, 12)}

The profit associated with these scenarios will be ...

for (0, 16): 16·350 = 5600

for (3, 12): 3·450 +12·350 = 1350 +4200 = 5550

To maximize profit, the farmer should plant 16 acres of barley.
