Answer:
the first one
Step-by-step explanation:
The problem says that the plot must have a maximum of 44, which means the most right dot must be on the 44 mark. All the graphs fit this requirement (the dashes are in increments of 2) The problem says that it must have an upper quartile of 39, which means the line closest to the maximum dot must be on the 39 mark. Graphs 2 and 3 do not meet this requirement, so they are eliminated. The last requirement is the median of 25. The median is represented by the middle line in the middle of the boxes. Graph 4 does not fit this requirement, so it is eliminated. Thus, only the first graph follows all 3 requirements.

(3x + 8)(3x + 8) = 0
(3x-8)(3x + 8) = 0
x(3x - 8) = 0
(3x-8)(3x - 8) = 0
= -8
Answer:
The answers to your questions are given below.
Step-by-step explanation:
1. (3x + 8)(3x + 8) = 0
3x + 8 = 0 or 3x + 8 = 0
3x = –8 or 3x = –8
x = –8/3 or –8/3
2. (3x – 8)(3x + 8) = 0
3x – 8 = 0 or 3x + 8 = 0
3x = 8 or 3x = –8
x = 8/3 or –8/3
3. x(3x – 8) = 0
x = 0 or 3x – 8 = 0
x = 0 or 3x = 8
x = 0 or 8/3
4. (3x – 8)(3x – 8) = 0
3x – 8 = 0 or 3x – 8 = 0
3x = 8 or 3x = 8
x = 8/3 or 8/3

The correct answer is 48
Step-by-step explanation:
if a graph shows no solution what is the inequality
If the number on the other side of the inequality sign is negative, your equation either has no solution or all real numbers as solutions. Use the sign of each side of your inequality to decide which of these cases holds. If the number on the other side of the inequality sign is positive, proceed to step 3.

A normal distribution has a mean of 102 and a standard deviation of 2.9.
What is the z-score of 105?
Enter your answer, rounded to the nearest hundredth, in the box.
Answer:
the z score of 105 is 1.03
Step-by-step explanation:
Given that
the mean is 102
And, the standard deviation is 2.9
We need to find the z score of 105
As we know that
Z score = (Observed value - mean) ÷ standard deviation
= (105 - 102) ÷ 2.9
= 1.03
Hence, the z score of 105 is 1.03

I need help to find m
Answer:
∠MNO = 75°
Step-by-step explanation:
∠mno = 1/2 ( arc MLP - arc MOP )
arc MLP = 241 and arc MOP = 91
so ∠MNO = 1/2 ( 241 - 91 )
241 - 91 = 150
150/2 = 75
Hence, ∠MNO = 75°

Using Cavalieri's Principle, what is the general formula for the volume of a cone?
Answer:
The volume for a cone and pyramid are the same, V = 1/3 Bh where B is the area of the base.
Step-by-step explanation:
So even though the base is a different shape, as long as the areas and heights are the same, they will have the same volume.

I did the test and it was right
In an article by researchers Meehl and Rosen (Psychological Bulletin, 1955), a diagnostic test was examined for detecting psychological adjustment in soldiers. A positive result indicates the solder is mal-adjusted whereas a negative result indicates well-adjusted. For soldiers known to be well-adjusted, the test gives a positive result 19% of the time. For soldiers known to be mal-adjusted, the test gives a positive result 55% of the time. The researchers believed that 5% of all soldiers are mal-adjusted. Suppose a soldier is selected at random and they test positive. What is the probability that soldier is mal-adjusted
Answer:
0.1322 = 13.22% probability that the soldier is mal-adjusted.
Step-by-step explanation:
Conditional Probability
We use the conditional probability formula to solve this question. It is
[tex]P(B|A) = \frac{P(A \cap B)}{P(A)}[/tex]
In which
P(B|A) is the probability of event B happening, given that A happened.
[tex]P(A \cap B)[/tex] is the probability of both A and B happening.
P(A) is the probability of A happening.
In this question:
Event A: Positive test
Event B: Soldier is mal-adjusted.
Probability of a positive test:
55% of 5%(mal-adjusted).
19% of 100 - 5 = 95%(well adjusted). So
[tex]P(A) = 0.55*0.05 + 0.19*0.95 = 0.208[/tex]
Probability of a positive test and soldier being mal-adjusted.
55% of 5%. So
[tex]P(A \cap B) = 0.55*0.05 = 0.0275[/tex]
What is the probability that the soldier is mal-adjusted?
[tex]P(B|A) = \frac{P(A \cap B)}{P(A)} = \frac{0.0275}{0.208} = 0.1322[/tex]
0.1322 = 13.22% probability that the soldier is mal-adjusted.
what is the y intercept of 2(x-2)^2+3
Write the slope-intercept form of the equation of the line.
9514 1404 393
Answer:
y = x + 2
Step-by-step explanation:
We observe that the line crosses the y-axis at y=2, so the y-intercept is 2.
The line has a rise of 1 grid square for each run of 1 grid square to the right. The slope is the ratio of rise to run:
m = rise/run = 1/1 = 1
The slope and intercept can be put into the slope-intercept form:
y = mx + b . . . . . line with slope m and y-intercept b
y = 1x +2 . . . . . . line with slope 1 and y-intercept 2
y = x +2 . . . . . . . simplified

Answer:
a = 4
b = 2√3
Step-by-step explanation:
The side lengths of a 30°-60°-90° right triangle are in the ratio 1 : √3 : 2.
The shortest side in the given triangle is 2, so we can multiply by 2 to see the ratios are ...
2 : 2√3 : 4 = 2 : b : a
b = 2√3
a = 4
The circumference of a circular painting is 40.82 feet. What is the radius of the painting? Use 3.14 for pie and do not round your answer.
Answer:
The radius is equal to 6.5 feet.
Step-by-step explanation:
To solve this we need to know that circumference equals 2πr (where "r" is the radius). Therefore, we can make the following equation...
2πr = 40.82
πr = 20.41
3.14r = 20.41
r = 6.5
Now we know that the radius is equal to 6.5 feet.

The slope of the line in the graph is 4. Fill in the y intercept. Choose the correct equation in the form y = mx + b The y intercept is: The equation is y =
Answer:
[tex]\rm\implies y = 4x + 3 [/tex]
Step-by-step explanation:
Given :-
The slope of the line in the graph is 4.And we need to find the equation of the line. On looking at the graph we see that , it cuts y axis at (0,3) .So the y Intercept of the equation is 3 .
Slope Intercept Form :-
[tex]\rm\implies y = mx + c[/tex]
Substituting the respective values :-
[tex]\rm\implies y = 4*x + 3 \\\\\rm\implies y = 4x + 3 [/tex]
Hence the equation of line is y = 4x + 3

1.What is the surface area of the prism? (1 point)
283.8 m²
292.4 m2
325.4 m²
407 m²
2. What is the lateral surface area of the prism? (1 point)
283.8 m²
292.4 m2
325.4 m²
407 m²
Answer:
The surface area is [tex]325.4m^2[/tex]
The lateral surface area is: [tex]292.4m^2[/tex]
Step-by-step explanation:
Given
[tex]L = 3m[/tex] -- Length
[tex]H =17.2m[/tex] --- Height
[tex]W = 5.5m[/tex] --- Width
See attachment for prism
Solving (a): The surface area
This is calculated as:
[tex]S.A = 2 * (LW + WH + LH)[/tex]
This gives:
[tex]S.A = 2 * (3*17.2 + 17.2 * 5.5 + 3 * 5.5)[/tex]
[tex]S.A = 2 * (51.6 + 94.6 + 16.5)[/tex]
[tex]S.A = 2 * 162.7[/tex]
[tex]S.A = 325.4m^2[/tex]
Solving (b): The lateral surface area
This is calculated as:
[tex]L = 2 * (L + W) * H[/tex]
So, we have:
[tex]L = 2 * (3 +5.5) * 17.2[/tex]
[tex]L = 2 * 8.5 * 17.2[/tex]
[tex]L = 292.4m^2[/tex]
