what is the median of this data set?
16,21,28,30,34,45,58,60

Answers

Answer:

32

Step-by-step explanation:

the median in a data set is the middle number. first, you are going to want to order the numbers in numerical order.

this is what it would look like.

16, 21, 28, 30, 34, 45, 58, 60

(basically how it is in the problem lol)

since there's an even number of numbers in the set, you have to take the mean of the two middle numbers. in this case, the two middle numbers are 30  and 34.

you take the mean of numbers by adding them, and then dividing them based on the number of numbers. (sorry if that doesn't make sense, just look down ehe)

(30+34)/2

we divide by two because there are two numbers.

(30+34)/2

(64)/2

32

if this didn't make sense - sorry - but you can watch this video: https://www.khanacademy.org/math/cc-sixth-grade-math/cc-6th-data-statistics/mean-and-median/v/mean-median-and-mode

BC 136m, AB 89m

BC 89m. AB 136m

BC 105m, AB 162m

BC 162m, AB 106m

Answers

Answer:

BC 136m, AB 89m

Step-by-step explanation:

Find the diagram attached

According to sin rule;

a/sinA = b/sinB = c/sinC

From the diagram;

b = 120m

<B = 60degrees

<C = 40degrees

From the sine formula

b/sinB = c/sinC

120/sin60 = c/sin40

csin60 = 120sin40

c = 120sin40/sin60

c = 120(0.6428)/0.8660

c = 77.1345/0.8660

c = 89.06

c = AB = 89m

Get BC;

According to the sine rule

a/sinA = b/sinB

a/sin(180-100) = 120/sin60

a/sin80 = 120/sin60

asin60 = 120sin80

a = 120sin80/sin60

a = 120(0.9848)/0.8660

a = 118.177/0.8550

a = 136.46

Hence a = BC = 136m

If y varies jointly as x and z and y = 4 when x = 2 and z = 3, what is y when x = -6 and z = 2?

Answers

Answer:

Step-by-step explanation:

Y = kxz

Putting values of y x and z in the equation

4 = k(2)(3)

4 = k6

2/3 = k

Now finding y when x = - 6 and z = 2

Y = kxz

= 2/3(-6)(2)

= - 8

How many grams are equal to 7 kilograms

There are 7000 grams are equal to 7 kilograms.

What is unit conversion?

Conversion of units means the conversion between different units and measurements of the same quantity done by the process of multiplication or division.

Given measurement

7 kilograms

In 1 kilogram = 1000 grams

In 7 kilograms = 7 × 1000 grams

In 7 kilograms = 7000 grams

Hence, 7000 grams are there in 7 kilograms.

De un depósito se gasta primero la mitad del agua, y luego la cuarta parte de lo que quedaba. Al final,
quedan 12 litros. Hallar la capacidad del depósito.

Answers

Answer:5/8 fraction of the deposit has been spent, which is 20 liters

Let "a" be the initial amount of water, then first half the water is used: then a / 2 of water is used and the other half is left at / 2 * (1/4), then the fourth part is used: then 1/8 * a is used, so now it remains: a / 2 - a / 8 = 3/8 * a, so 5/8 * a has been used, then what remains are 12 liters:

3/8 * a = 12 L

a = 12 L * 8/3 = 32 L

Wasted: 32 L - 12 L = 20 L

christen has to run around the rectangle soccer field during practice. The soccer field measures 60 meters long by 45 meters wide. How far did christen run?

Answers

Answer:

210 m

Step-by-step explanation:

Perimeter is the distance around the outside of a two-dimensional shape.

Area is the space inside of a two-dimensional shape. We can also think of area as the amount of space a shape covers.

Christen ran around the soccer field, so she ran around the perimeter.

We can find the perimeter by adding all of the side lengths.

Perimeter=60 m+45 m+60 m+45 m

Christen ran 210m.

An airplane flies 105 miles per half an hour. How far can it fly in 1.25 hours at the same speed. Brainliest for correct answer. (ANSWER ISN't 262.5)

Answers

262.5 should be the correct answer though. 105/30=3.5 so the plane is approximately traveling at 3.5 miles per minute. 3.5x60= 210 so at an hour it has traveled 210 miles. Then we must find .25 of an hour which is 15 minutes. 15x 3.5=52.5. Add both the hour value and the .25 of an hour value together and it is 262.5 miles.

Answer:

Airplane fly 262.5miles far.

solution given:

rate=105 miles per 0.5 hour=210miles per hour

distance =rate ×time=210×1.25=262.5miles

What is the total area of each garden bed has a length of 4 feet Amelia

Answers

64 feet squared because 4 cubes

Answer:

48 ft^2.

Step-by-step explanation:

In this case, our formula is known as 3s^2 which can be written out as 3 x s x s or 3(s x s). S is the variable to represent our length and width because the formula for finding the area is l x w which can be written out as length x width. If the total area of each garden bed has a length of 4 feet, our equation would be 3(4 x 4) or 3 x 4 x 4 or 3(4)^2. 4 x 4 or 4^2 is 16. If we multiply 16 by 3, the answer would be 48. That is why the total area of each garden bed would be 48 ft^2.
