Step-by-step explanation:

Minimum:

Minimum of the data set is the smallest value in the data set.

Median:

Median is the value in data set that divides the data arranged in ascending order in two equal parts.

First Quartile:

A median divides the data arranged in ascending order in two equal parts. The lower half and the upper half. The lower half consists of values less than median and the upper half consists of values greater than the median. First quartile is the value in data that divides the lower half into two equal parts. It can also be called the median of lower half. It is denoted by Q_1 . About 25% of the numbers in the data set lie below Q_1 and 75% values lie above the first quartile.

Third Quartile:

The third quartile is the value in data set that divides the upper half of the data into two equal parts. It can also be called the median of the upper half.

It is denoted by Q_3. 75% values of the data set lie below third quartile and 25% value lie above it.

Maximum:

The maximum of a data is the largest value in the data set..

9th out of 10 questions

Mazyrski [523]

Hello! When dividing fractions, you multiply by the reciprocal of the second fraction. So 2/3 divided by 1/2 would be 2/3 times 2.

As you can see, the first fraction would be the same. Therefore, a will be 4. 5 and 6 will swap, so b will be 6 and c will be 5.

Therefore, our answer is D) a=4, b=6, c=5

I hope this helps!

Keiko's Coffee Shop makes a blend that is a mixture of two types of coffee. Type A coffee cost Keiko $4.15 per pound, and type B

Kay [80]

Answer:

39 pounds of type A coffee were used.

Step-by-step explanation:

Given: Cost of type A coffee is $4.15 per pound and cost of type B coffee is $5.25 per pound. Also, blend used four times as many pounds of type B coffee as type A.

To find: How many pounds of type A coffee were used.

Let $x$ be the number of pounds of type A coffee and $y$ be the number of pounds of type B coffee.

Then, according to question,

$4.15x+5.25y=980.85$ and $y=4x$

Substituting $y=4x$ in $4.15x+5.25y=980.85$ , we get

$4.15x+5.25(4x)=980.85$

⇒ $4.15x+21x=980.85$

⇒ $25.15x=980.85$

⇒ $x=\frac{980.85}{25.15}$

⇒ $x=39$

Therefore, 39 pounds of type A coffee were used.

The distance, D, that a spring is stretched by a hanging object varies directly as the weight, W, if the object. An object weigh

Dmitriy789 [7]

The distance the spring will be stretched with an object weighing 29 kilograms is 47 centimeters

<h3>Variation</h3>

From the question, we are to determine the distance the spring will be stretched with an object weighing 29 kg

From the given information,

The distance, D, that a spring is stretched by a hanging object varies directly as the weight, W, if the object

That is,

D ∝ W

Then, we can write that

D = kW

NOTE: k is the constant of proportionality

Also, from the given information,

An object weighing 30 kilograms stretched the spring 49 centimeters

That is,

D = 49 cm

W = 30 kg

Putting the parameters into the equation to solve for k, we get

49 = k × 30

∴ k = 49/30

Now, for the distance stretched when weight is 29 kg

Using D = kW, we get

D = (49/30) × 29

D = 1421/30

D = 47.367

D ≅ 47 cm

Hence, the distance the spring will be stretched with an object weighing 29 kilograms is 47 centimeters

Classify each pair of numbered angles.

Ksju [112]

Answer:

Angles 1 & 2 are vertical angles, and angles 3 & 4 are adjacent angles.

Step-by-step explanation:

Vertical angles are angles across from each other. Adjacent angles are always beside each other.

It's not a linear pair because a linear pair is adjacent angles that add up to 180°, which is not true for your 2 angles in the picture. Hope this helps!!!

A superhero can fly from New York to Los Angeles in 30 minutes. The distance from New York to Los Angeles is approximately 2450

bulgar [2K]

Answer:

So the superhero covers 2450 miles in 30 minutes or 1/2 hour

Thus, he/she will cover (2450 x 2) miles in 1 hour

Therefore the answer is his/her velocity is (2450 x 2) miles/hour = 4900 miles/hour.

Hope this helps!
