Formulate the situation as a system of inequalities. (Let x represent the number of dinghies the company can manufacture and y r
kirill [66]

Answer:

x (smallest to largest) = 0,45 ,55

y (smallest to largest) = 0,10,40

Step-by-step explanation:

(hours)        Dinghy Rowboat        Labor Available

Metal Work 2             3                       120

Painting         2              2                        110

Let x represent the number of dinghies the company can manufacture and y represent the number of rowboats.

So, total hours for metal work = 2x+3y

So, total hours for Painting = 2x+2y

So, equation becomes:

2x+3y\leq 120

2x+2y\leq 110

x\geq 0

y\geq 0

Plot the inequalities

Refer the attached figure

So, the vertices of the feasible region are (0,40),(45,10) and (55,0)

So, x values are 0 , 45 and 55

x represents the number of dinghies

So, x (smallest to largest) = 0,45 ,55

y values are 40,10,0

y represent the number of rowboats.

So, y (smallest to largest) = 0,10,40

Volgvan

Answer:

Binomial Distribution

Step-by-step explanation:

In this case there are only two possible outcomes that is either the processor requires repair or does not require.

In such cases binomial distribution is beneficial to use.

Binomial Distribution is simply the probability of failure or success in an experiment that is repeated multiple times.

for binomial to be used following three conditions are to be used:

1. Fixed number of trails

2. Each trial or observation is independent

3. probability of success is exactly same

Rachel runs 6 miles in 50 minutes. At the same rate, how many miles would she run in 35 minutes?
Naily [24]

Answer: 4.2 miles

Step-by-step explanation:

So she ran 6 miles in 50 minutes how long will she run in 35 minutes?

So the equation will therefore be:

6=50

x=35

Cross multiply

6 x 35 = 50x

210 = 50x

Divide both sides by 50

The answer is 4.2 miles

The side lengths of a triangle are 9, 12, and 15. Is this a right triangle?
Ierofanga [76]

Answer:

Step-by-step explanation:

Those are the side lengths not the angles so I'm not sure, also are you sure that's right? I believe there has to be a hypotenuse and the hypotenuse is the sum of the two shorter sides added together.

Do you have any more information? I can try to help :)
