The line plot shows the heights of the players on a basketball team, in inches.
Part B
he next year, a player who is
71
inches tall is replaced by a player who is
73
inches tall. Otherwise the team remains the same. Is
74
an outlier the next year? Explain.
A: based on the given dot plot are: statements B, D, and E.
B: A. No. 74 is not an outlier because it is not different from the other heights in the dot plot.
What is a Dot Plot?In a dot plot, frequencies of each data point is represented as dots.
Part A:
Thus, in the dot plot given:
Players of 70 1/2 in. tall and above are 7 in number. This is half of the number of the total players. (option B is true).
Players with height of 69 1/2 in. (3 players) are more than those that are 70 in. tall (1). (option A is not true).
One of the player is 68 1/2. (option C is not true).
Four of the players are 74 in. tall (option D is true).
The team has 6 different heights as shown in the dot plot given (option E is correct).
Therefore, the statements that are correct based on the given dot plot are: statements B, D, and E.
Part B:
If a player of 73 in. tall replaces a player of 71 in, tall, 73 is close to 74.
Therefore, we can conclude that: A. No. 74 is not an outlier because it is not different from the otehr heights in the dot plot.

Mike is working on solving the exponential equation 74^x = 37; however, he is not quite sure where to start. Using complete sentences, describe to Mike how to solve this equation.
Answer:
Method 1
[tex]74^x = 37[/tex]
Take natural logs of both sides:
[tex]\implies \ln74^x = \ln37[/tex]
Apply the log power rule: [tex]\ln(a)^b=b \ln (a)[/tex]
[tex]\implies x\ln74 = \ln37[/tex]
Divide both sides by ln 74:
[tex]\implies \dfrac{x\ln74}{\ln74} = \dfrac{\ln37}{\ln74}[/tex]
[tex]\implies x= \dfrac{\ln37}{\ln74}[/tex]
[tex]\implies x=0.8389552282...[/tex]
Method 1
[tex]74^x = 37[/tex]
Take logs of base 74 of both sides:
[tex]\implies \log_{74}74^x = \log_{74}37[/tex]
Apply the log power rule: [tex]\log_am^n=n\log_am[/tex]
[tex]\implies x\log_{74}74= \log_{74}37[/tex]
Apply log of the same number as base rule: [tex]\log_aa=1[/tex]
[tex]\implies x= \log_{74}37[/tex]
[tex]\implies x=0.8389552282...[/tex]
Answer:
[tex]x = \log_{74}(37) [/tex]
Step-by-step explanation:
we want to solve the following exponential equation:
[tex] \iff {74}^{x} = 37[/tex]
Taking common logarithm of both sides yields:
[tex]\iff \log{74}^{x} = \log37[/tex]
recall that,
[tex] log( {a}^{x} ) = x log(a) [/tex]utilizing it yields:
[tex] \iff x \cdot\log{74} = \log37[/tex]
divide both sides by log74:
[tex]\iff \dfrac{ x \cdot\log{74}}{ \log(74)} = \dfrac{ \log37}{ \log(74) }[/tex]
remember that,
[tex] log_b( {a} ) = \frac{log(a)}{log(b)} [/tex]
hence,
[tex]x = \boxed{ \log_{74}(37)} [/tex]
What is the equation to this graph using Y=MX+B. Show Work.
Answer:
y = 2x + 9
Step-by-step explanation:
Y = mx + b indicates slope-intercept equation.
"b" represents y -intercept/beginning.
"mx" represent slope/constant of variation/rate of change
x-intercept represents the end of the graph. (in stories using money its the ending amount).
The y-intercept is always when the x-value is 0. The point of the y-intercept is on the y-axis. The line on the graph starts at the point (0,9). It can be located on the point right above the number labeled under the 9 which is 8. Since the x-value is 0,
The y-intercept is 9.
To find the slope, we have to find two points on the graph to use.
Two points on the graph are:
(1.5, 13) , (2, 14)
Using the slope formula:
y2-y1/x2-x1
Plug in:
14-13/2-1.5
Complete:
1/0.5
divide:
The numbers in 1 divided by 1/2 are labeled below:
1 = whole number
1 = numerator
2 = denominator
To make it a fraction form answer, you multiply the whole number by the denominator and make the result the new numerator. The old numerator becomes the new denominator:
1 x 2/1 = 2/1
Thus, the answer to 1 divided by 1/2 in fraction form is:
2/1
To make the answer to 1 divided by 1/2 in decimal form, you simply divide the numerator by the denominator from the fraction answer above:
2 / 1 = 2
The answer is rounded to the nearest two decimal points if necessary.
2/1 is an improper fraction and should be written as 2.
So now that we have the y-intercept and slope:
Y-intercept: 9
Slope: 2
Equation: y = 2x + 9

Answer: The first term of a GP is 6 if it's common ratio is 2 find the 6th term
The nth term is ar^(n-1)
So, for your GP, the 6th term is 6*2^5 = ___
Step-by-step explanation: 10:2021
The value of 16th term in the geometric series is,
⇒ 6th term = 192
What is Geometric sequence?An sequence has the ratio of every two successive terms is a constant, is called a Geometric sequence.
Given that;
The first term is 6 and the common ratio is 2.
Hence, We can formulate;
⇒ nth term = arⁿ⁻¹
⇒ 6th term = ar⁶⁻¹
⇒ 6th term = ar⁵
⇒ 6th term = 6 (2)⁵
⇒ 6th term = 6 x 32
⇒ 6th term = 192
Thus, The value of 16th term in the geometric series is,
⇒ 6th term = 192

A. The graph off has a relative minimum or relative maximum at x = C.
B. The graph off has an inflection point at x = C.
C. The graph off has an x-intercept at x = C.
D. None of the above is necessarily true.
Answer: D
Step-by-step explanation:
f'(C) = 0 ⇒ There is a critical point here
There could be a relative max or min here, but since we do not know if f''(x) is positive or negative, we cannot be sure if the function is truly changing from positive to negative or vice versa. "C" could simply be at a horizontal tangent of a function like x³.

Origami paper is always in the shape of a square. If you take the top corner of either side of a 9 x 11-inch piece of paper and fold it to the lower opposite side and trim off the excess paper, this creates the square that we need. Then fold the top corner to the opposite corner to create a diagonal, which is a typical first step to most origami designs. What are the dimensions of your square? What is the length of the diagonal? Write your answer in exact and decimal form.
Answer:
Dimensions are nine by nine, the diagonal is the square root of 162.
Step-by-step explanation:
The resulting square will have the same width as before, with a height to match, (9,9) The diagonal can be found using the pathagyreon theorom.
9^2 + 9^2 = x^2.
The dimensions of the square would be nine by nine, the diagonal is the square root of 162.
The square will have the same width as before, with a height to match, (9,9)
