A school had a lot of problems with
student absences and wanted to try a
intervention program to see if it
encouraged students to come to school
more often. As a trial, 20 students were
split into two equal size groups. Group 1
would get the new intervention and
Group 2 got no intervention. The mean-
number of absences was calculated after
one month for each group, as shown in
the table below. What inference can be
made about the results?

Answers

The inference is that the results of the study are statistically significant.

How to make the inference about the results?

For group 1, we have:

Mean = 1.7

For group 2, we have:

Mean = 3.3

The mean of group 2 is greater than group 1, and the mean difference is:

Difference = 3.3 - 1.7

Evaluate

Difference = 1.6

Based on the sample values, the mean difference of 1.6 is significant.

Hence, the inference is that the results of the study are statistically significant.

Work out the surface area of this cylinder. 8 cm 16.8 cm

Answers

The complete question is

" Work out the surface area of this cylinder if the diameter of the cylinder is 8 cm and height is 16.8 cm."

The surface area of the cylinder of diameter 8 cm and height 16.8 cm would be 547.616 cm sq.

What is the surface area of the cylinder?

The surface area of the cylinder of the radius of the base r and the height h,

A = 2πr ( r + h)

We have been given as

diameter = 8 cm

Height = 16.8cm

The radius = 8/2 = 4cm

The surface area of the cylinder

A = 2πr ( r + h)

A = 2 x 3.14 x 4 ( 4 + 16.8)

A = 25.12 (21.8)

A = 547.616 cm sq.

Hence, The surface area of the cylinder of diameter 8 cm and height 16.8 cm would be 547.616 cm sq.

Answer:

(-14, 12) and (5, 12)

Step-by-step explanation:

From inspection of the points given, we can see that all pairs of points share the same y-values.

Therefore, each pair of points are on the same horizontal line.

To find the distance between the points, simply find the difference between the x-values.

Given points:  (-14, 12) and (5, 12)

⇒ Difference between x-values = 5 - (-14) = 19 units

Given points:  (-5, 19) and (12, 19)

⇒ Difference between x-values = 12 - (-5) = 17 units

Given points:  (-20, 5) and (1, 5)

⇒ Difference between x-values = -20 - 1 = -21 = 21 units

Given points:  (14, 12) and (5, 12)

⇒ Difference between x-values = 14 - 5 = 9 units

Answers

The length and the width of the outside edge of the garden will be ( 6x + 12 ) and ( 9x + 6 ) respectively.

What is the scale factor?

In mathematics, a scale factor is the proportion of related dimensions of an object to a description of that object.

Given that:-

The outside edges of the walkway form a rectangle whose length and width are proportional to the sides of the garden, increased by a scale factor of 3. the sides of the garden are (2x+4) and (3x+2)

The length and width of the outside edge will be:-

The sides are Dilated by factor 3 so the edges of the rectangle will be calculated as;-

Length = 3 ( 2x+4 ) = 6x + 12

Width   = 3 ( 3x+2 ) = 9x + 6

The time taken for the rocket to reach the ground can be found on the graph by finding the x-intercept, at which the height (y-value) will be 0

According to the graph :

The x-intercept is (5.04, 0)Hence, it takes the rocket 5.04 seconds to reach the ground after takeoff

Observe the end points on x axis of the parabola

They are

Answers

The equation that models the height of the baseball is determined as H(t) = 5 + 49.64t -16(t)².

Maximum height reached by the base ball

The maximum height reached by the baseball is calculated as follows;

H = y₀ + v₀yt + ¹/₂gt²

Assuming negative direction for upward motion

H = y₀ + v₀yt - ¹/₂gt²

0 = y₀ + vt -16(t)²

0 = 5 + 3.2v - 16(3.2)²

0 = 5 + 3.2v - 163.84

3.2v = 158.84

How many combinations of 3 playing cards (from a 52-card deck) exist?
25,000
1,649
523

its not 22,100 btw....

Answers

523 should be your answer

Answer:

Step-by-step explanation:

To determine the number of combinations of 3 playing cards from a standard 52-card deck, we can use the formula for combinations, which is given by:

C(n, k) = n! / (k!(n-k)!)

Where n is the total number of items (in this case, the number of cards in the deck) and k is the number of items chosen (in this case, 3 cards).

Plugging in the values:

n = 52 (total number of cards in the deck)

k = 3 (number of cards chosen)

C(52, 3) = 52! / (3!(52-3)!)

Calculating the factorial terms:

52! = 52 x 51 x 50 x ... x 3 x 2 x 1

3! = 3 x 2 x 1

(52-3)! = 49! = 49 x 48 x ... x 3 x 2 x 1

Simplifying the equation:

C(52, 3) = 52 x 51 x 50 / (3 x 2 x 1)

Cancelling out the common factors:

C(52, 3) = (52 x 17 x 25) / (3 x 2 x 1)

C(52, 3) = 22,100

Therefore, there are 22,100 combinations of 3 playing cards that can be chosen from a 52-card deck.

Answers

The sides of the triangle are (d) 12√2, 12√2, 24

How to determine the side lengths?

The given parameters are:

Hypotenuse = 24Angle = 45-45-90 degree angles

In a 45-45-90 degree angle triangle, we have:

Hypotenuse = Opposite√2 and Hypotenuse = Adjacent√2

This means that:

Opposite =Adjacent

So, we have:

24 = Adjacent√2

Divide both sides by √2

Adjacent = 24/√2

Evaluate

Adjacent = 12√2

This means that:

Opposite = 12√2

Hence, the sides of the triangle are (d) 12√2, 12√2, 24

Since [tex]\overline{GH} \parallel \overline{DE}[/tex], by the corresponding angles theorem, [tex]\angle FGH \cong \angle FDE, \angle FHG \cong \angle FED[/tex]. This means [tex]\triangle FGH \sim \triangle FDE[/tex] by AA.

Their plan is to study a rectangular area of the moon by placing a grid over the map as shown. On the grid, 1 unit represents 1 kilometer (km).the Rover will land at (3.5,1) , explore up to (3.5,4), and then over (2,4). PART A. what are the coordinates of the fourth vertex of the rectangle that the scientist plan to explore ?PART B. what is a horizontal length of the rectangle? what is the vertical length of the rectangle PART C. find the area of the Moon exploration area in square kilometers.
