What is the Common denominator for 3 1/3 and 2/5

Answer:

360

Step-by-step explanation:

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)

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:

Thus, 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)

Answer:

The answer is -3

Step-by-step explanation:

When negative three is put into the equation, making it -3x + 17 = -3x + 19. there are no solutions because when solved the answer to that equation is 17 = 19, which is not true.

Step By Step Solving

-3x +17 = -3x + 19 - move the -3x to the other side by adding 3x to both sides.

17 = -3x + 3x + 19 - solve -3 + 3 and -x + x = 0 to get the answer

17 = 19 - which is not true so there are no solutions when the missing number is -3.

Answer:

A cylinder's volume is π r² h, and its surface area is 2π r h + 2π r².

Answer:

Step-by-step explanation:

1.5m

(2500mm)/(1000 mm/m) = 2.5m

(850mm)/(1000 mm/m) = 0.85m

4.8m

Add the number of meters:

1.5 + 2.5 + 0.85 + 4.8 = 9.65m

We have the given measurements 1.5 m, 2500 mm, 850, 4.8m. Therefore, the total length would be 9.65m.

One meter is equal to 1000 millimeters. So, to convert one millimeter into a meter we have to divide by 1000.

We have the given measurements 1.5 m, 2500 mm, 850, 4.8m

To convert a millimeter into a meter

2500 mm

= (2500mm)/(1000 mm/m)

= 2.5m

850mm

(850mm)/(1000 mm/m)

= 0.85m

Add the number of meters:

= 1.5 + 2.5 + 0.85 + 4.8

= 9.65m

Therefore, the total length would be 9.65m.

i got confused so i j filled in the table. mark as brainliest please :)

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.

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.

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.

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.

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

Answer:

-8+2x is less than 5 and - 8+2x is less than 5

Because it contains the points (0, 0) and (pi/2, 1), the first 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.
