A Company Produces Items In Small Batches The Machinery Needs To Warm Up Before The Atom Can Be Produced

Answers

Answer 1

Answer: B. It takes about 20 minutes for the equipment to warm up

Step-by-step explanation:

Took the quiz

Answer 2

The true statement is 'It takes about 20 minutes for the equipment to warm up.'

The correct answer is an option (B)

What is the line of the best fit?

"It is a line through data points that best expresses the relationship between those points."

What is y-intercept?

"It is the points at which the graph of function intersects the Y-axis."

What is the slope of the line?"It is the change in y coordinate with respect to the change in x coordinate.""The slope of the line passing through points [tex](x_1,y_1),(x_2,y_2)[/tex] is [tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]"What is the slope-intercept form of the line?

"The slope-intercept form of the line, y = mx + b where m is the slope and b is the y-intercept."

For given question,

From the scatter plot, the line of the best fit passes through the points   (3, 44) and (5, 60)

We find the slope of the line of best fit.

Let [tex](x_1,y_1)=(3,44),(x_2,y_2)=(5,60)[/tex]

Using slope formula,

[tex]\Rightarrow m=\frac{y_1-y_1}{x_2-x_1}\\\\\Rightarrow m=\frac{60-44}{5-3} \\\\\Rightarrow m=\frac{16}{2}\\\\ \Rightarrow m=8[/tex]

Also, the Y-intercept of the line of best fit is 20.

Using the slope-intercept form, the equation of the line of best fit would be,

y = 8x + 20

From this equation we can say that,

As the number of items in a batch is increases by 1, the production time increases by 8 minutes and it takes about 20 minutes for the equipment to warm up.

Therefore, the correct statement is 'It takes about 20 minutes for the equipment to warm up.'

The correct answer is an option (B)

Solve the proportion 40/z+1 = 15/6

Answers

Answer:

z = 15

Step-by-step explanation:

[tex] \frac{40}{z + 1} = \frac{15}{6} \\ [/tex]

Cross multiply

That's

[tex]15(z + 1) = 40(6) \\ 15z + 15 = 240[/tex]

Send 15 to the right side of the equation

[tex]15z = 240 - 15 \\ 15z = 225[/tex]

Divide both sides by 15

[tex] \frac{15z}{15} = \frac{225}{15} \\ [/tex]

We have the final answer as

z = 15

A = [tex]\frac{h}{2} (a + b)[/tex]

First off, we need to multiply both sides by [tex]\frac{2}{h}[/tex] to cancel out the [tex]\frac{h}{2}[/tex].

[tex]\frac{2A}{h}[/tex] = a + b

Now, we need to subtract b from both sides.

[tex]\frac{2A - b}{h}[/tex] = a

We get the answer to be:

A farmer is selling bushels of cornWhen a bushel has inedible stalks, the supermarket gets a discount on the entire bushel. The farmer profits $8 per bushel with all edible stalks and loses $4 for every bushel with inedible stalks. If 95% of the bushels have all edible stalks and % have inedible stalks, what is the expected profit the farmer makes?

Answers

Answer: $7.80

Step-by-step explanation:

Based on the information given in the question, the expected profit that the farmer makes will be:

= (Probability of edible stocks × Profit) - (Probability of inedible stocks × Loss)

= (95% × $8) - (5% × $4)

= (0.95 × $8) - (0.05 × $4)

= $7.60 + $0.20

= $7.80

Therefore, the expected profit that the farmer makes is $7.80.

For example, if you sleep poorly the night before a big exam, will you do worse? Dr. Kushner is especially curious about selective sleep deprivation, where people are kept from entering REM (rapid eye movement) sleep. Using an electroencephalograph (EEG) to monitor brain waves, he plans to let participants sleep until they enter REM sleep and then wake them. After the participants are awake for one minute, Dr. Kushner plans to let them return to sleep. As they enter REM sleep again, he will wake them again and follow the same procedure. He plans to do this through the entire eight-hour sleep session.
