Answer:
Option B.
Step-by-step explanation:
From the given statements the true about the process of statistics. are:
1. Data are typically collected from a sample because it is too difficult and expensive to collect data from an entire population.
2. When the results from a sample are extended to the population, it is called inference.
3. If data are not collected properly, the conclusions that are drawn will be meaningless.
But, the first step in the process of statistics is to collect the data. This is not true about the process of statistics because the first step in the process of statistics is identify the research objective.
Therefore, the correct option is B.
The statement about the process of statistics that is not correct is: B. The first step in the process of statistics is to collect the data.
The Process of StatisticsThe first step in a statistical process is to first determine the research objective.Next is to draw a sample that represents the population under study from which to collect data from.The data collected from the sample is then analyzed and interpreted in order to make inference about the population that was studied.The meaningfulness and soundness of the conclusions drawn depends on how accurate the data collected are.Therefore, the statement about the process of statistics that is not correct is: B.

Answer: 5) 72.6° 6) 68.7° 7) 37.3° 8) 81.5°
Step-by-step explanation:
Law of Cosines: a² = b² + c² - 2bc · cos A
b² = a² + c² - 2ac · cos B
c² = a² + b² - 2ab · cos C
5) a = 27, b = 26, c = 20, A = ???
a² = b² + c² - 2bc · cos A
27² = 26² + 20² - 2(26)(20) · cos A
729 = 676 + 400 - 1040 cos A
729 = 1076 - 1040 cos A
-311 = -1040 cos A
[tex]\dfrac{311}{1040}=\cos A\\\\\cos^{-1}\bigg(\dfrac{311}{1040}\bigg)=A[/tex]
72.6° = A
6) a = 11, b = 13, c = 12, B = ???
b² = a² + c² - 2ac · cos B
13² = 11² + 12² - 2(11)(12) · cos B
169 = 121 + 144 - 264 cos B
169 = 265 - 264 cos B
-96 = -264 cos B
[tex]\dfrac{96}{264}=\cos B\\\\\cos^{-1}\bigg(\dfrac{96}{264}\bigg)=B[/tex]
68.7° = B
7) a = 19.2, b = 11.7, c = 16.5, B = ???
b² = a² + c² - 2ac · cos B
11.7² = 19.2² + 16.5² - 2(19.2)(16.5) · cos B
136.89 = 368.64 + 272.25 - 633.6 cos B
136.89 = 640.89 - 633.6 cos B
-504 = -633.6 cos B
[tex]\dfrac{504}{633.6}=\cos B\\\\\cos^{-1}\bigg(\dfrac{504}{633.6}\bigg)=B[/tex]
37.3° = B
8) a = 8.8, b = 12.4, c = 14.1, C = ???
c² = a² + b² - 2ab · cos C
14.1² = 8.8² + 12.4² - 2(8.8)(12.4) · cos C
198.81 = 77.44 + 153.76 - 218.24 cos C
198.81 = 231.2 - 218.24 cos C
-32.39 = -218.24 cos C

Answer: 348 in²
Step-by-step explanation:

Step-by-step explanation:
The population describes the data from which the sample size is gotten.
Now, we are told that A quality control manager randomly selects 40 bottles of orange juice that were filled on june 12 to assess the calibration of of the filling machine.
This means that the sample size is 40 bottles. The population from which this sample is gotten is therefore:
bottles of orange juice that were filled on june 12.

3 is a number that is a polynomial with a single term.
Therefore, the given expression is a polynomial.
Hence Option (C) is the answer.
3 can be written as 3x⁰ (Since x⁰ = 1)
Therefore, degree of the polynomial is 0.
Option (A). degree of the polynomial = 0
What is the answer for 10-6(5-2y)
Answer:
-20 + 12y
Step-by-step explanation:
Equation: 10 - 6(5 - 2y)
Step 1:
10 - 30 + 12y Multiply (5 - 2y) by -6 (distributive property)
Step 2:
-20 + 12y Subtract 10 by 30 (10 - 30 = -20)
Answer:
[tex]12y-20[/tex]
Step-by-step explanation:
First, we need to distribute.
[tex]= 10+(-6)(5)+(-6)(-2y)= 10+-30+12y[/tex]
Now, we need to combine these terms.
[tex]=10+-30+12y=(12y)+(10+-30)=12y+-20[/tex]
The answer is

Answer:
k = 7/3
Step-by-step explanation:
Let's first find the equation of line AC. Since point A has an x-coordinate of 0, we know that point A is the y-intercept so when writing the equation of AC in slope-intercept form, we know that b = -2 in y = mx + b (Note that m = slope and b = y-intercept). To find m, we can use points A and C, therefore, m = (0 - (-2)) / (-2 - 0) = 2 / -2 = -1. Now, we know that the equation of line AC is y = -x - 2. To solve for k, we know that point B belongs to AC and that x = -k, y = 5 - 2k in point B, therefore, after plugging those values into y = -x - 2, we get:
5 - 2k = -(-k) - 2
5 - 2k = k - 2
5 - 3k = -2
-3k = -7
k = 7/3

Hopefully it helps!
Please mark brainliest :)
The mid - point between the numbers is 6.545.
We have two decimal numbers → 6.54 and 6.55
We have to determine their mid - point.
You have two numbers - 'x' and 'y'. Find the mid - point between these two numbers.The midpoint (n) between these two numbers will be -
[tex]$n=\frac{x+y}{2}[/tex]
According to the question, we have -
Number 1 → 6.54
Number 2 → 6.55
Assume the mid - point be n. Therefore -
n = [tex]\frac{6.54+6.55}{2}[/tex] = 6.545
Hence, the mid - point between the numbers is 6.545.

How does the area of the scale drawing where 1 centimeter represents 10 miles compare to the area of a the drawing where 1 centimeter represents 30 miles? Area if 1 cm= 10 mi: square miles Area if 1 cm = 30 mi: square miles The area would be times as great.
Answer:
100 square miles900 square miles9 times as greatStep-by-step explanation:
It seems rather obvious that ...
(1 cm)^2 ⇒ (10 mi)^2 = 100 mi^2 . . . on the first drawing
(1 cm)^2 ⇒ (30 mi)^2 = 900 mi^2 . . . on the second drawing
The area on the second drawing is 900/100 = 9 times as great.
_____
These are the areas represented by 1 square cm on the scale drawing. If the drawing is larger, then the represented area is correspondingly larger. The ratio of represented areas is still 9 times for drawings of the same size.
