Answer:

78.5

Step-by-step explanation:

The diameter (d) is equal to the radius x 2, so take half of d to get r. Use r (5) in the equation to get your answer.

A= 3.12 x 5^2

A= 78.5

Answer:

56

Step-by-step explanation:

degree of freedom is n - 1, n being the sample size

One sample of 57 participants in a study (given)

For this study, n = 57

Using the degree of freedom formula, 57 - 1 = 56

Hope it helps, Let me know if yoy have any more questions/concerns !

Have a nice rest of your day :)

→The angle between the two segments is marked by a little square which indicates that it’s a right angle in other words the segments are perpendicular.

Answer:

40 problems.

Step-by-step explanation:

I am assuming you are asking what the total number of problems is.

24*100 is 2400

2400/60 is 40

4x=13

Step-by-step

add 3 to both sides making 10=13

4x=13

Answer:the answer would be equal to.

Step-by-step explanation:

The matrix that is equal to the considered matrix [-6,-6.5,1.7;  2, -8..5, 19.3 ] is given by: Option D:  [-6,-6.5,1.7;  2, -8..5, 19.3 ]

Two matrices are equal if and only if their shapes are same, and they've got the same elements for each corresponding row and column positions.

The missing options are specified in the image attached below.

The considered matrix is:

[tex]\left[\begin{array}{ccc}-6&-6.5&1.7\\2&-8.5&19.3\end{array}\right][/tex]

It has 2 rows and 3 columns.

Evaluating each of the options:

Option A and B are wrong as they've got 3 rows and 2 columns, which makes their shape not matching with the shape of the considered matrix.

Option C although has got 2 rows and 3 colums, but its elements are not matching with corresponding elements of the considered matrix.

Option D has 2 rows and 3 colums and its each element matches with the corresponding element of the considered matrix. (ie, for example, element common in first row and first column in option D is -6, and so as for the considered matrix, and similarly, all correspoding elements for each row and column is same in both matrices.)

Thus, the matrix that is equal to the considered matrix [-6,-6.5,1.7;  2, -8..5, 19.3 ] is given by: Option D:  [-6,-6.5,1.7;  2, -8..5, 19.3 ]

Answer:

perfect square trinomial^^

Answer:

what is mean: mean is the "average" of a set of numbers and it is calculated by adding up the values given and dividing by the total number of values given.

Step-by-step explanation:

formula: addition of all values divided by the number of values given.

total number of values given = 10 ( count each number as one )

so ..

20+15+22+13+14+18+19+11+23+17 = 172

divided by 10

= 17.2 ( decimal)

or 17 whole number 1/5 ( mixed fraction )

or 86/5 ( improper fraction ).

Hope this helps.

Good luck .

Step-by-step explanation:

The top left box on the x axis is negitive 3

Answer:

Step-by-step explanation:

You would add probabilities if you want to find out if one event or another could happen. For example, if you roll a die, and you wanted to know the probability of rolling a 1 or a 6, then you would add the probabilities:

Probability of rolling a 1: 1/6

Probability of rolling a 6: 1/6

So the probability of rolling a 1 or a 6 is 1/6 + 1/6 = 2/6 = 1/3.

Answer:

30

Step-by-step explanation:

6/1 x 5/6 = 30/6 or 5.

5/1 divided by 1/6 is 5/1 x 6/1 or 30.

Therefore, the answer is 30.

Answer:

It's C. 30

2/6  x  d   = 388

d = 388 x 6/2 = 1164 m

Answer:

The total distance covered in miles is B, 1164 miles.

Step-by-step explanation:

Since we know that 2/6 of his total trip distance is 388 miles we can do 388 / 2/6 = 1164. Therefore, his total trip distance is 1164 miles.

Answer:

180

Step-by-step explanation:

This is 180 because the specific angles in a triangle will unless an irregularly shaped triangle will equal up to 180.

Answer:

5 ft

Step-by-step explanation:

If all sides are of the same length, we can multiply the value of one side by 3, because a triangle has three sides (and the perimeter is all sides added together), to find the perimeter.

[tex]1\frac{2}{3}[/tex] × 3

[tex]1\frac{2}{3}[/tex] can be rewritten as [tex]\frac{5}{3}[/tex], so:

[tex]\frac{5}{3}[/tex] × [tex]\frac{3}{1}[/tex]

[tex]= \frac{15}{3}[/tex]

The numerator & denominator share a common factor of 3, so:

5 ft is the final answer/perimeter.

Answer:

Step-by-step explanation:

Beth's position over time is constant, which makes the problem a lot easier. You are asked for the rate of position versus time, so begin by doing that. Since the rate is constant, clearly from the table, you can take any two data points and take their ratio. Her rate would be 11 feet every 5 seconds, or equivalently 2.2 feet every second. To graph the data, put position on the y-axis and time on the x-axis. The slope will be 2.2 at every point along her bike ride.

Moving on to the third part. If Amy traveled at a rate of 75 feet every 30 seconds, then she would be traveling 2.5 feet every second. Amy's rate is larger than Beth's rate. Since the rate corresponds to the slope of the postion vs. time graph, Amy's graph will have a steeper incline since the slope is 2.5

Answer:

B. Every 5 minutes 11 ft. traveled

2.2ft.= every 1 minute

C. Steeper. this is because her rate of change is much higher than before

The student T distribution would be used since we don't know the population variance (by extension the population standard deviation).

However, if n > 30, then the student T distribution is going to look very similar to the standard normal Z distribution. It won't be a perfect match, but it'll be close enough that it's more simple to use the Z distribution. With the Z distribution, you only have one set of values and you don't have to worry about the degrees of freedom.

its actually just r=-2
