Answer:

B. None of these plants is yet producing actual widgets.

Step-by-step explanation:

As we can see in the graph, the number of days is on the x axis, and the number of widgets at y axis.

At 10 days, no line is above the '0' means no one is producing widgets at 10 days point.

Since the y axis represents number of widgets produced, this means none of the plants have produced more than 0 widgets yet.

So, option B is the answer.

SOMEONE PLSSSS HELP!!! Explain the difference in the graphs of Car #1 and Car #2. What is the Slope of each? Why is one line ste

dusya [7]

Answer:

Car 1 slope = 35

Car 2 slope = 40

Red line(car 2) is steeper than the blue line(car 1)

slope is miles per gallon

Step-by-step explanation:

Slope formula is

$slope = \frac{y_2-y_1}{x_2-x_1}$

To find slope, pick two points from graph of Car 1

(4,140) (6,210)

$slope Car1= \frac{210-140}{6-4}$ = 35

To find slope, pick two points from graph of Car 2

(3,120) (5,200)

$slope Car 2= \frac{200-120}{5-3}$ = 40

When slope is larger then line is steeper

slope of Car 2 is greater than slope of Car1

So Red line is steeper than the blue line.

Slope is change is y over change in x

It means Change in miles over change in gallons

So slope is miles per gallon

Can someone help me with translation

Arte-miy333 [17]

Answer:

P' = (4, 4)

Step-by-step explanation:

T(x, y) is a function of x and y. Put the x- and y-values of point P into the translation formula and do the arithmetic.

P' = T(8, -3) = (8 -4, -3 +7) = (4, 4)

_____

Comment on notation

The notation can be a little confusing, as the same form is used to mean different things. Here, P(8, -3) means point P has coordinates x=8, y=-3. The same form is used to define the translation function:

T(x, y) = (x -4, y+7)

In this case, T(x, y) is not point T, but is a function named T (for "translation function") that takes arguments x and y and gives a coordinate pair as a result.

Type the correct answer in the box. Use numerals instead of words. If necessary, use / for the fraction bar.

arsen [322]

Answer:

The probability that a randomly chosen person gets an incorrect diagnosis is 2.965% = 0.02965.

Step-by-step explanation:

Given, The test to detect the presence of a liver disorder is 98% accurate for a person who has the disease.

so, probability of incorrect diagnosis = 100-98 = 2% = 0.02.

and 97% accurate for a person who does not have the disease.

so, probability of incorrect diagnosis = 100-97 = 3% = 0.03.

And 3.5% of the people in a given population actually have the disorder.

⇒ the probability that a randomly chosen person gets an incorrect diagnosis is (3.5% × 0.02) + (96.5% × 0.03) = 2.965% = 0.02965.

The school cafeteria sells three different types of sandwiches: chicken, turkey,

dusya [7]

Answer:

Number of chicken sandwiches = 150

Number of turkey sandwiches = 150

Number of roast beef sandwiches= 100

Step-by-step explanation:

We are told the school cafeteriat makes and sells 3 different types of sandwiches which are; chicken, turkey and roast beef.

Let chicken be x, turkey be y and roast beef be z.

We are told they make 400 sandwiches in total.

Thus;

x + y + z = 400

However, we are told that the cafeteria makes same number of chicken and turkey sandwiches.

Thus, x = y

Thus;

Total is now;

x + x + z = 400

2x + z = 400 - - - (eq 1)

Now,we are told that chicken, turkey and roast beef sandwiches are sold for $3, $3.5 and $4 respectively. Also that the total amount realized from sales is $1375.

Thus;

3x + 3.5y + 4z = 1375

Since x = y. Thus;

3x + 3.5x + 4z = 1375

6.5x + 4z = 1375 - - - (eq 2)

Let's make z the subject in eq 1.

Thus;

z = 400 - 2x - - - (eq 3)

Putting 400 - 2x for z in eq(2) gives us;

6.5x + 4(400 - 2x) = 1375

6.5x + 1600 - 8x = 1375

1600 - 1375 = 8x - 6.5x

225 = 1.5x

x = 225/1.5

x = 150

Putting 150 for x in eq 3 gives;

z = 400 - 2(150)

z = 400 - 300

z = 100

Since x = y. Then y = 150

.can you help please

sweet [91]

Answer:

38.81cm³

Step-by-step explanation:

Volume of a sphere = 4/3πr³

Diameter is 4.2

radius= 4.2/2 = 2.1 or 21/10

4/3 × 22/7 × 21/10 × 21/10 × 21/10

= 4851/125

= 38.808

≈38.81cm³
