Answer:
median
Step-by-step explanation:
because you have the smallest to the largest number and its one to five so once it counts from one to five its median
Answer:
Its Either B or C.
Step-by-step explanation:
So, the median and the interquartile range are the most appropriate measures to describe the center and the variation.The range is a measure of variability because it indicates the size of the interval over which the data points are distributed. A smaller range indicates less variability (less dispersion) among the data, whereas a larger range indicates the opposite.

Answer:
2) 54 units
3) 2770 square units
Step-by-step explanation:
2) The perimeter is the sum of the lengths of the sides of the figure. The sum of the lengths of the horizontal segments is 2×16 = 32 units. All but one of the lengths of the vertical segments are given. The missing one is the inside segment on the left side, which is 9 - (6 -2) = 5 units. Then the sum of vertical segment lengths is 9 +5 +2 +6 = 22 units. The total perimeter is ...
P = 32 units + 22 units = 54 units
__
3) The centerline of the green region is 60×2 units plus the circumference of a circle 50 units in diameter. That centerline length is ...
60×2 +50×3.14 = 120 +157 = 277 . . . units
The width of the region is 10 units, so the total area of the green region is ...
A = LW = (277 units)(10 units) = 2770 square units

14. Students in a statistics class would like to investigate if more than two-thirds of the Earth is water.
To answer this question, students tossed an inflatable globe back and forth. After each catch, the
student recorded whether the tip of their pointer finger of their right hand was on water or land. In
50 tosses, their finger was on water 38 times. Assuming all conditions for inference are met, do the
data provide convincing statistical evidence at the significance level of a = 0.05 that more than two-
thirds of the Earth is water?
(A) Yes, because the p-value of 0.76 is greater than the significance level of 0.05.
(B) Yes, because the p-value of 0.08 is greater than the significance level of 0.05.
(C) Yes, because the p-value of 0.05 is less than the significance level of 0.08.
(D) No, because the p-value of 0.08 is greater than the significance level of 0.05.
(E) No, because the p-value of 0.03 is less than the significance level of 0.05.
Answer:
D
Step-by-step explanation:
No, because the p-value of 0.08 is greater than the significance level of 0.05.
No, there isn't convincing statistical evidence at the significance level of a = 0.05 because the p-value of 0.08 > 0.05. (Option D)
How to find the corresponding value of z test statistic for a value of proportion random variable?Suppose the population proportion mean be denoted by [tex]\hat{p}[/tex]
and the population proportion random variable be denoted by p
Then, the z-test statistic's value for [tex]p = p_0[/tex] for sample of size n is specified by
[tex]z = \dfrac{\hat{p} - p_0}{\sqrt{\dfrac{p_0(1-p_0)}{n}}}[/tex]
For this case, we're specified that:
Students in a statistics class would like to investigate if more than 2/3 of the Earth is water.Sample size = 50Favorable cases = 38Level of significance = 0.05Thus, sample proportion is:
[tex]\hat{p} = \dfrac{38}{50} = 0.76[/tex]
(1) Null and Alternative Hypotheses
The following null and alternative hypotheses for the population proportion needs to be tested:
[tex]\begin{array}{ccl} H_0: p & \leq & 2/3\\ H_a: p & > & 2/3 \end{array}[/tex]
This corresponds to a right-tailed test, for which a z-test for one population proportion will be used.
(2) Rejection Region
Based on the information provided, the significance level is [tex]\alpha = 0.05[/tex], and the critical value for a right-tailed test is [tex]z_c = 1.64[/tex]
The rejection region for this right-tailed test is [tex]R = \{z: z > 1.645\}[/tex]
(3) Test Statistics
The z-statistic is computed as follows:
[tex]\begin{array}{ccl} z & = & \displaystyle \frac{\hat p - p_0}{\sqrt{ \displaystyle\frac{p_0(1-p_0)}{n}}} \\\\& = & \displaystyle \frac{0.76 - 2/3}{\sqrt{ \displaystyle\frac{ 2/3(1 -2/3)}{50}}} \\\\ & = & 1.401 \end{array}[/tex]
(4) Decision about the null hypothesis
Since it is observed that [tex]z = 1.401 \le z_c = 1.645[/tex], it is then concluded that the null hypothesis is not rejected.
Using the P-value approach: The p-value is p = 0.0806, and since [tex]p = 0.0806 \ge 0.05[/tex], it is concluded that the null hypothesis is not rejected.
(5) Conclusion
It is concluded that the null hypothesis H₀ is not rejected. Therefore, there is not enough evidence to claim that the population proportion pp is greater than 2/3, at the [tex]\alpha = 0.05[/tex] significance level.
Thus, there isn't convincing statistical evidence at the significance level of a = 0.05 because the p-value of 0.08 > 0.05. (Option D)

Step-by-step explanation:
the height of a house having three rooms of the dimensional 9 feet into 12 feet 14 feet into 16 feet and 12 feet into 14 feet respectively is 90 Feet what will be the amount required to paint on all was from inside at the rate of 160 per square feet
Answer:
Amount required = 2,217,600
Step-by-step explanation:
Dimensions of the rooms are as follows;
Room 1; 9 feet × 12 feet
Room 2; 14 ft × 16 ft
Room 3; 12 ft × 14 ft
Perimeter of rooms;
P1 = 2(9 + 12) = 42 ft
P2 = 2(14 + 16) = 60 ft
P3 = 2(12 + 14) = 52 ft
Total perimeter; P = 42 + 60 + 52 = 154 ft
Height is 90 ft.
Thus, total area is;
A = 154 × 90
A = 13860 ft²
Rate of painting is 160 per Sq.ft.
Thus amount to paint entire area = 160 × 13860 = 2217600

p(x + h)
= (x + h)3 + (x + h)
= x3 + 3x2h + 3xh2 + h3 + x + h
StartFraction p (x + h) minus p (x) Over h EndFraction = StartFraction (x cubed + 3 x squared h + 3 x h squared + h cubed + x + h) minus (x cubed + x) Over h EndFraction
What is the simplified expression for the difference quotient for all nonzero values of h?
3x2 + 3xh + h2
3x2 + 3xh + h2 + 1
3x2 + 3xh + h2 + h
3x2 + 3xh + h2 + 2x + 1
Answer:
The answer is B
Step-by-step explanation:
The simplified expression for the difference quotient for all nonzero values of h is 3x² + 3xh + h² + 1 option (B) is correct.
What is a function?It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.
It is given that:
The function is:
p(x) = x³ + x
The difference quotient of the function:
p(x + h) = (x + h)³ + (x + h)
The difference quotient of the function:
= [((x + h)³ + (x + h)) - (x³ + x)]/h
= [x³ + 3x²h + 3xh² + h³ + x + h - x³ - x]/h
= [3x²h + 2xh² + h³ + h]/h
= 3x² + 3xh + h² + 1
Thus, the simplified expression for the difference quotient for all nonzero values of h is 3x² + 3xh + h² + 1 option (B) is correct.

A function assigns the values. The last column in the table is needed to be filled as (-2,2), (0,4), and (2,10), respectively.
What is a Function?A function assigns the value of each element of one set to the other specific element of another set.
Given the value of x and the value of y is needed to be calculated using the function y=3x+4. Also, in the last column, the value of x and y is needed to be written in the form of a coordinate. Therefore, the value of y can be written as,
x=-2
y=3x+4
y=3(-2)+4
y = -2
x=0
y=3x+4
y=3(0)+4
y=4
x=2
y=3(2)+4
y=10
Hence, the last column in the table is needed to be filled as (-2,2), (0,4), and (2,10), respectively.

Select the graph of y= sin x.
Because it contains the points (0, 0) and (pi/2, 1), the first graph is the graph of sin(x).
Which graph is the graph of sin(x)?To identify the graph of sin(x), we need to remember some points of the sine function.
We know that sin(0) = 0, this means that this passes through the point (0, 0).
And we also know that sin(pi/2) = 1, then it also passes through the point (pi/2, 1).
With that in mind, the graph that passes through those two points is the first one, so that is the correct option.
