Answer:

Marko bikes approximately 16.13 miles.
A very slow rate.

Step-by-step explanation:

average speed = 534 minutes per mile

time taken = 8614

d = t/s

distance = 8614 / 534

= 16.13 miles

Final answer:

The student's mean score in the class is calculated as 80.6

The average of a group of variables is referred to as the mean in mathematics and statistics. There are several methods for calculating the mean, including simple arithmetic means (adding the numbers together and dividing the result by the number of observations), geometric means, and harmonic means. The mean represents the average or middle value of all the data in a dataset as a single number. One of many measures of central tendency, it is also referred to as the arithmetic average.

The mean is significant because it reveals the location of the dataset's median value. Because it contains data from each observation in a dataset, the mean is also significant.

Explanation:

Let [tex]x1 = 62, x2 = 83, x3=91, x4=88, x5=76[/tex]

Test scores count for 20% of the grade, final grades for 25%, and homework grades for 15% of the grade. Therefore

[tex]w1 = w2= w3 = 0.20\\w4 = 0.25\\w5 = 0.15[/tex]

[tex]= > \frac{12.4 + 16.6 + 18.2 + 22+11.4}{1}[/tex]

Which becomes,

[tex]= 80.6[/tex]

According to weights proportionate to values in the final grade, the weighted mean yields the mean value. The observed values are multiplied by the weights, which are then divided by the total number of weights.

Answer:

V = [tex]\frac{Bh}{3}[/tex]

Step-by-step explanation:

B = 3 × [tex]\frac{V}{h}[/tex] ( multiply both sides by h to clear the fraction )

Bh = 3V ( divide both sides by 3 )

Answer:

we assume the two boys lifted the same amount of weight of boxes. Let s be the weight of the boxes Steven lifted. Hence,

Step-by-step explanation:

13 ( s+12) = 15 s

where s + 12 means that the box lifted by Nathan weighed 12 more than that of Steven.

we solve,

s = 78 pounds

such that Nathan's is 90 pounds.

In a survey of 232 professional athletes, 23 athletes do not own any of the three items. 49 owns a convertible and a tv, but not a store. 163 athletes owns a convertible or a tv. 109 athletes owns exactly one type of item in the survey. 209 athletes owns at least one type of item in the survey. 55 owns a tv or a store, but not a convertible.

Using Venn diagram, a diagram used to present the relationship between sets in a logical form, we analyze the given information.

athletes who do not own any of the three items = 232 - (121 + 100 + 93) +(54 + 38 + 18) - 5 = 23

athletes who owns a convertible and a tv, but not a store = 54 - 5 = 49

athletes who owns a convertible or a tv = (121 + 93) - (18 + 38 - 5) = 163

athletes who owns exactly one type of item in the survey = (121 - 54 - 18 + 5) + (100 - 38 - 54 + 5) + (93 - 18 - 38 + 5) = 109

athletes who owns at least one type of item in the survey = 121 + 100 + 93 - 54 - 38 - 18 + 5 = 209

athletes who owns a tv or a store, but not a convertible = (100 - 54 -38 + 5) + (93 - 18 - 38 + 5) = 55

The true statement is sometimes true

The equation is  given as

5x + 3 - 2x = 7x + 3

Evaluate the like terms on each side of the equation

So, we have

3x + 3 = 7x + 3

Evaluate the like terms on both sides

4x = 0

Divide both sides by 4

x = 0

This means that the equation is only true when x = 0

To solve the for x the equation will be   3x° = 80° - x° and the value of x is 20°.

When two or more lines meet at a common point it is known as  intersecting lines.

According to the question we have been given that there are two lines who are intersection at a point. And we have been given measure of two angles.

Let the first angle be given as ∠A and the second angle be given as ∠B.

The measure of angles given to us are :

   ∠A = 3x°  and  ∠B = (80 - x)°

We know that when two lines intersect then the vertically opposite angles are equal, that is

              ∠A = ∠B

Putting the required values we get

            3x° = 80° - x°

            4x° = 80°

              x = 20°

Hence the value of x = 20°. Thus the measure of ∠A = 60°  and ∠B = 60°

The distance between the two points ( − 4 , - 5 ) and ( 0 , 5 ) is 10 units.

We are given the two points:

( − 4 , - 5 ) and ( 0 , 5 )

We need to find the distance between the two points.

The formula for distance is given as:

Distance = √ (x₂ - x₁)² + (y₂ - y₁)²

Substituting the values, we get that:

Distance = √ ( 0  + 4 )² + ( 5 + 5)²

Distance = √ ( 4 )² + ( 10 )²

Distance = √ 16 + 100

Distance = √ 116

Distance = 2 √29 units.

Therefore, we get that, the distance between the two points ( − 4 , - 5 ) and ( 0 , 5 ) is 2 √29 units.

The coordinates of the ends of the line segment A''B'' are A''(x, y) = (3, 3) and B''(x, y) = (- 1, 7), respectively. The graph of the line segment is attached aside.

In this problem we must find the coordinates of a new line segment, generated after making translations and rotation, two kinds of rigid transformations. First, determine the coordinates of the ends of the line segments by translation formula:

A'(x, y) = (3, 4) + (- 2, 1)

A'(x, y) = (1, 5)

B'(x, y) = (- 1, - 2) + (- 2, 1)

B'(x, y) = (- 3, 1)

Second, determine the coordinates of the ends of the line segment by using the rotation formula:

A''(x, y) = O(x, y) + ((A'x - Ox) · cos θ - (A'y - Oy) · sin θ, (A'x - Ox) · sin θ + (A'y - Oy) · cos θ)

A''(x, y) = (1, 3) + ((1 - 1) · cos (- 90°) - (5 - 3) · sin (- 90°), (1 - 1) · sin (- 90°) + (5 - 3) · cos (- 90))

A''(x, y) = (1, 3) + (2, 0)

A''(x, y) = (3, 3)

B''(x, y) = O(x, y) + ((B'x - Ox) · cos θ - (B'y - Oy) · sin θ, (B'x - Ox) · sin θ + (B'y - Oy) · cos θ)

B''(x, y) = (1, 3) + ((- 3 - 1) · cos (- 90°) - (1 - 3) · sin (- 90°), (- 3 - 1) · sin (- 90°) + (1 - 3) · cos (- 90))

B''(x, y) = (1, 3) + (- 2, 4)

B''(x, y) = (- 1, 7)

The coordinates of the ends of the line segment A''B'' are A''(x, y) = (3, 3) and B''(x, y) = (- 1, 7), respectively. The graph of the line segment is attached aside.

∠2≅∠3 because ∠1≅∠2 and ∠1≅∠3. Hence proved.

Given that, AD bisects ∠BAC and ∠1≅∠3.

An angle bisector is defined as a ray, segment, or line that divides a given angle into two angles of equal measure. The word bisector or bisection means dividing one thing into two equal parts.

Since AD bisects ∠BAC, ∠BAD=∠DAC.

That is ∠1≅∠2 (AD bisects ∠BAC into two equal angles)

Since ∠1≅∠2 and ∠1≅∠3 (given)

Remember that for a general linear function we have:

y = a*x + b

Where a is the rate of change and b is the y-intercept.

Then comparing our function with the general one, we can see that the rate of change is 1/2.

Now, because the rate of change is positive, we can see that when x tends to infinity the function also tends to infinity.
