DiKsa [7]2 years ago

Find the median of each set:-

Median is middle number of a data set. If a data set has an odd number of numbers then the median is the middle number when ordered form least to greatest but if its an even number you have to find the mean for the middle 2 numbers when ordered for least to greatest. 

A.

1.2, 2.4, 3.2, 3.2, 3.6, 4.0, 4.1, 4.7

Even numbers = 8
3.2 + 3.6 = 6.8
6.8 ÷ 2 = 
Median = 3.4
So this shows that A isn't the answer because the median of A is 3.4, not 3.2. 

B.

1.6, 2.8, 2.9, 3.1, 3.3, 3.6, 4.2, 4.5

Even numbers = 8
3.1 + 3.3 = 6.4
6.4 ÷ 2 = 3.2
Median = 3.2
<span>So this shows that B is the answer because the median of B is 3.2.

C. 

1.8, 2.0, 2.0, 2.2, 3.2, 4.7, 4.8, 4.9
</span>
Even numbers = 8
2.2 + 3.2 = 5.4
5.4 ÷ 2 = 2.7
Median = 2.7
<span>So this shows that C isn't the answer because the median of C is 2.7, not 3.2.
</span>
D. 

1.4, 1.7, 2.9, 3.0, 3.1, 3.2, 3.2, 3.2, 4
Odd numbers = 9
Median = 3.1

<span>So this shows that D isn't the answer because the median of D is 3.1, not 3.2.
</span>
The stem and leaf plot which median is 3.2 is B.

How many cubic centimeters of water can this paper cone cup hold?
Igoryamba

Answer:

150.72 cubic centimeter

Step-by-step explanation:

Given:-

Height of cone (h) = 9cm

Diameter of cone(d)=8cm

radius of cone(r)=\frac{d}{2}=\frac{8}{2} =4cm

To calculate= Volume of cone(V_{cone})

Volume\ of\ cone(V_{cone}) =\frac{1}{3} \times \pi \times r^{2} \times h

=\frac{1}{3} \times 3.14\times 4^{2} \times 9

Volume of cone(V_{cone}) =150.72\ cubic\ centimeter

Therefore paper cone cup can hold 150.72 cubic centimeter of water.

A positive integer is 5more than 23 times another. Their product is 6732. Find the two integers
aliina [53]

One integer is m.

The other integer is n.


n = 23m + 5

mn = 6732


m = 6732/n


n = 23 * 6732/n + 5


n = 154,836/n + 5


n^2 = 154,836 + 5n


n^2 - 5n - 154,836 = 0


n = [5 +- sqrt(25 + 4 * 154,836)]/2


n = (5 +- 787)/2


n = 396 or n = -391


We discard -391 because the problem is looking for positive integers.


mn = 6732


m = 6732/n = 6732/396


m = 17


Answer: The integers are 17 and 396.
