Answer:

24.5

Step-by-step explanation:

The mean is calculated as

mean = [tex]\frac{sum}{count}[/tex]

The consecutive terms in the sequence have a common difference d

d = 7 - 2 = 12 - 7 = 17 - 12 = 5

This indicates the sequence is arithmetic with sum to n terms

[tex]S_{n}[/tex] = [tex]\frac{n}{2}[/tex] [ 2a₁ + (n - 1)d ]

where a₁ is the first term and d the common difference

Here a₁ = 2 and d = 5 , thus

[tex]S_{10}[/tex] = [tex]\frac{10}{2}[/tex] [ (2 × 2) + (9 × 5) ]

     = 5(4 + 45)

     = 5 × 49 = 245 , then

mean = [tex]\frac{245}{10}[/tex] = 24.5

Answer:

A. Miguel has the greatest spread.

The range of the two persons can be determined by:

Adam's range = 106 -91 = 15

Miguel's range = 105 -86 = 19

B. Considering the middle 50% of the training time, the person with the least spread is Adam.

Adam - 103 105 104 106 100

Miguel - 88 86 89 93 105

Adam's 50% range = 106 - 100 = 6

Miguel's 50% range = 105 - 86 = 19

Adam has the least spread

C. Miguel is inconsistent with the time set for training compared to that of Adam.

The answers to parts 2a and 2b show that there is a wide variation in the time that Miguel spend during training, but a minimum variation in the time spent by Adam during training.

The answers to parts 2a and 2b show that there is a wide variation in the time that Miguel spends during training, but a minimum variation in the time spent by Adam during training.

The interquartile range is a measurement of a data set's "middle fifty." A range is a measurement of where a set's beginning and end are located.

A. Miguel has the greatest spread.

The range of the two persons can be determined by:

Adam's range = 106 -91 = 15

Miguel's range = 105 -86 = 19

B. Considering the middle 50% of the training time, the person with the least spread is Adam.

Adam - 103 105 104 106 100

Miguel - 88 86 89 93 105

Adam's 50% range = 106 - 100 = 6

Miguel's 50% range = 105 - 86 = 19

Adam has the least spread

C. Miguel is inconsistent with the time set for training compared to that Adam.

Therefore to parts, 2a and 2b show that there is a wide variation in the time that Miguel spends during training, but a minimum variation in the time spent by Adam during training.

Answer:

250 questions

Step-by-step explanation:

65 is equal to 26% of the total number of questions so:

65 / total number of questions (x) is equivalent to 26 / 100

(65 and 26 are a fraction of the whole thing. it doesn't matter whether they go on the numerator or denominator, as long as they are either both on one or the other)

65/x = 26/100

you can simplify this into

26x = 6500

/26    /26

then you divide by 26 on both sides to isolate the variable

x = 250

Answer:

9h

Step-by-step explanation:

l x w x h

that's the formula of volume

Answer:

A. 9h

Step-by-step explanation:

The formula for the volume of a cube is:

side * side * side.

We know that each side is the same length, and we know all the sides, but this question has a variable for one side of the cube.

So, we get 3 * 3 * h which is 9h.

x = -7

The reason why Leslie is wrong is because: D. Her conclusion is wrong. If the rate of change is not constant, then the function cannot be linear.

A linear function can be defined as a type of function whose equation is graphically represented by a straight line on the cartesian coordinate.

This ultimately implies that, a linear function is typically used for uniquely mapping an input variable to an output variable, with the pair of points having a constant of proportionality.

Mathematically, the rate of change can be calculated by using this formula;

Rate of change = (Change in y-axis, Δy)/(Change in x-axis, Δx)

Rate of change = (y₂ - y₁)/(x₂ - x₁)

Rate of change = (-3 - (-4))/(0 - (-1))

Rate of change = 1/1

Rate of change = 1

For the other points chosen, the rate of change is given by:

Rate of change = (5 - (-3))/(2 - (-1))

Rate of change = 8/2

Rate of change = 4.

In conclusion, Leslie is wrong is because the rate of change or constant of proportionality for these data points are not the same.

Complete Question:

Leslie analyzed the graph to determine if the function it represents is linear or non-linear. First she found three points on the graph to be (-1, -4), (0, -3), and (2, 5). Next, she determined the rate of change between the points (-1, -4) and (0, -3) to be (-3 - (-4))/(0 - (-1)) = 1 and the rate of change between the points (0, -3) and (2, 5) to be (5 - (-3))/(2 - (-1)) = 8/2 = 4. Finally, she concluded that since the rate of change is not constant, the function must be linear. Why is Leslie wrong?

Answer:

Step-by-step explanation:

We note that the coefficient of y in equation (iii) is 1, so it is convenient to use that equation to eliminate y from the others.

__

To eliminate the y-variable from equation (i), four times equation (iii) can be added to equation (i).

To eliminate the y-variable from equation (ii), three times equation (iii) can be subtracted from equation (i).
