Answer:

The actual length of car is <u>48 feet</u>.

Step-by-step explanation:

Given:

Tiffany sketched a picture of a car she used the scale 2 inches : 12 feet.

In her sketch the car is 8 inches long.

Now, to find the length in feet of the actual car.

Let the actual length of car in feet be x\ feet.

And the length of car in her sketch is 8 inches.

<em>So, the ratio of the scale used by Tiffany as given is 2 inches : 12 feet.</em>

Now, to get the actual length of car by using cross multiplication method:

\frac{2\ inches}{12\ feet} =\frac{8\ inches}{x\ feet}

⇒ \frac{2}{12} =\frac{8}{x}

<em>By cross multiplying we get:</em>

⇒ 2x=96

<em>Dividing both sides by 2 we get:</em>

⇒ 48=x

⇒ x=48\ feet.

Therefore, the actual length of car is 48 feet.

Mkey [24]

Answer:

Step-by-step explanation:

given that a batch of 140 semiconductor chips is inspected by choosing a sample of 5 chips without replacement.

10 chips do not conform to customer requirements.

i.e. out of 140 chips 10 are defective and 130 are good

a) 5 chips can be selected form 140 chips in 140C5 ways

= 416965528

b) For containing exactly one non conforming chip we have one selected from 10 and other 4 selected from 130

No of ways = 10C1 (130C4)\\=10(11358880)\\=113588800

c) For atleast one nonconforming chip we can calculate as total - no non conforming

i.e. 416965528-130C5\\= 416965528-286243776\\=130721752

Setler [38]

Answer:

12 students

Step-by-step explanation:

Given

Students = 54

Required

Determine the number of students that eat lunch once a week

In Sets;

If out of 9, at least 7 eats one a week then

9 - 7 eats lunch once a week

9 - 7 = 2

<em>In other words;</em>

2 out of 9 students eat lunch once a week

Number of students in this category is then calculated as thus;

Number = \frac{2}{9} * 54

Number = \frac{2 * 54}{9}

Number = \frac{108}{9}

Number = 12

Find the average rate of change of f(x) = -x² + 5x+2 from x=3 to x=6.
ivolga24 [154]

9514 1404 393

Answer:

  -4

Step-by-step explanation:

The points at the ends of the interval are ...

  (3, f(3)) = (3, 8)

  (6, f(6)) = (6, -4)

The slope is given by the slope formula:

  m = (y2 -y1)/(x2 -x1)

  m = (-4 -8)/(6 -3) = -12/3 = -4

The average rate of change is -4.
