Determine the MEDIAN of the following numbers: 8, 11, 11, 12, 13, 15, 16, 16,
18, 21
15
13
14
21
Answer:
Step-by-step explanation:
Determining Median is super easy!
1. Order the numbers, in ascending order.
8, 11, 11, 12, 13, 15, 16, 16, 18, 21
2. Cross off one number from both ends until you reach the middle number, whether you're left with one or two.
11, 11, 12, 13, 15, 16, 16, 18
11, 12, 13, 15, 16, 16
12, 13, 15, 16
13, 15
3. Determine the average of these two numbers.
(13 + 15) / 2
28 / 2
14
The median for this set of data is 14.
P.S. the average only needs to be calculated when left with two numbers, if you are left with only one, that number is your answer!
Hope this helps :)
Answer:
The median of the following numbers is 14

. Seven cards are numbered from 1 to 7 and placed in a box. One card is selected at random, then replaced. Another
card is randomly selected. What is the probability of selecting two odd numbers?
Answer:
Im not sure, but I can give advice!
Step-by-step explanation:
Study and wach yt vids (: hope I helped a bit!
Answer:
25/59
Step-by-step explanation:
Since there are 5 odd cards and 7 cards total, the probabilty of drawing an odd card is 5/7.
he probability of two events happening is the probability of each multiplied together, so multiply 5/7 by 5/7 to get 25/49.
A population of bacteria P is changing at a rate based on the function given below, where t is time in days. The initial population (when t = 0) is 900. dP dt = 2900 1 + 0.25t Write an equation that gives the population at any time t. Then find the population when t = 2 days. (Round your answer to the nearest whole number.)

Find the altitude of the triangle.
30 degrees
Hypotenuse of 14
Answer:
Approx. 12.124 units tall
Step-by-step explanation:
Since you need to find the height (which is adjacent to the given angle), you need to use cosine (adj. over hypotenuse).
cos(30) = x/14
Multiply both sides by 14:
14cos(30) = x

Why do we need to learn about Statics? What are its capabilities?
Answer:
I DID NOT WRITE THIS
Step-by-step explanation:
Statistical knowledge helps you use the proper methods to collect the data, employ the correct analyses, and effectively present the results. Statistics is a crucial process behind how we make discoveries in science, make decisions based on data, and make predictions.
Answer:
Statistics is the science and, arguably, also the art of learning from data. As a discipline it is concerned with the collection, analysis, and interpretation of data, as well as the effective communication and presentation of results relying on data.
Step-by-step explanation:
Statistics are important because today we live in the information world and much of this information's are determined mathematically by Statistics Help. It means to be informed correct data and statics concepts are necessary. They use their statistical skills to collect the relevant data.

4. Suppose the probability of event A is 0.23, the probability of the intersection of event A and event Bis 0.12, and
the probability of the union of event A and event B is 0.34. Find the probability of the complement of event B.
(A) 0.11
(B) 0.23
(C) 0.48
(D) 0.52
(E) 0.77
Answer:
[tex]P(B') = 0.77[/tex]
Step-by-step explanation:
Given
[tex]P(A) = 0.23[/tex]
[tex]P(A\ n\ B) = 0.12[/tex]
[tex]P(A\ u\ B) = 0.34[/tex]
Required
Find P(B')
First, we calculate P(B).
We have:
[tex]P(A\ n\ B) = P(A) + P(B) - P(A\ u\ B)[/tex]
Substitute values
[tex]0.12 = 0.23 + P(B) - 0.34[/tex]
[tex]0.12 = 0.23 - 0.34 + P(B)[/tex]
Collect like terms
[tex]P(B) = 0.12 - 0.23 + 0.34[/tex]
[tex]P(B) = 0.23[/tex]
P(B') is then calculated as:
[tex]P(B') = 1 - P(B)[/tex]
[tex]P(B') = 1 -0.23[/tex]
[tex]P(B') = 0.77[/tex]

What is the product of 1/4x-1/2 and 5x^(2) - 2x + 6? Write your answer in standard form. Show your work. Please this is due by tomorrow :c
Solution:
(4x2 - 2x) - (-5x2 - 8x)
= 4x2 - 2x + 5x2 + 8x.
= 4x2 + 5x2 - 2x + 8x.
= 9x2 + 6x.
= 3x(3x + 2).
Answer: 3x(3x + 2)
Solution:
(4x2 - 2x) - (-5x2 - 8x)
= 4x2 - 2x + 5x2 + 8x.
= 4x2 + 5x2 - 2x + 8x.
= 9x2 + 6x.
= 3x(3x + 2).
Answer: 3x(3x + 2)
Solution:
(4x2 - 2x) - (-5x2 - 8x)
= 4x2 - 2x + 5x2 + 8x.
= 4x2 + 5x2 - 2x + 8x.
= 9x2 + 6x.
= 3x(3x + 2).
Answer: 3x(3x + 2)

A 10 meter ladder is leaned up against a building. If
the angle of elevation is 60 degrees, what is the
height of the building?
Answer:
8.7
Step-by-step explanation:
Use trigonometry. The ladder and the building form a right triangle with the ground. You are given the length of the hypotenuse and the base angle. You use sine since we are trying to figure out the opposite side from the angle and we have the hypotenuse length. Sin = opposite/hypotenuse. So in this case, sin 60°= x/10. We solve for x by multiplying both sides by 10. Now x= sin 60° (10) = (0.8660)(10) = 8.7 m.
Find the discount.
Original price: $0.75
Discount: ??
Sale price: $0.15
Answer:
80%
Step-by-step explanation:
0.75 ⇒ 100%
0.15 ⇒ x%
0.75x = 100·(0.15)
0.75x = 15
x = 15/(0.75)
x = 1500/75
x = 20%
100% - (discount) = x%
100% - (discount) = 20%
discount = 100%-20%
discount = 80%
Answer:
60% off

The points (11, 13) and (7, 13) fall on a particular line. What is its equation in slope-intercept form?
Answer:
slope -intercept form y=mx+c
The equation of the straight line
y = 0x +13
Step-by-step explanation:
Step(i):-
Given that the points
(11 ,13) and (7,13)
The slope of the line
[tex]m = \frac{y_{2}-y_{1} }{x_{2} -x_{1} } = \frac{13-13}{7-11} = \frac{0}{-4} =0[/tex]
Step(ii):-
Equation of the straight line passing through the point (11,13) and slope m=0
y - y₁ = m( x-x₁)
y - 13 =0(x-11)
y-13 =0
y =13
slope -intercept form y=mx+c
y = 0x +13
