ASSET Math 1 Answer Key

Step-by-step explanation:

C is the correct answer

The distance Train A travels is represented by d = 80t, where d is the distance in kilometers
and t is the time in hours. The distance Train B travels at various times is shown in the
table. What is the rate of each train? Which train is going faster?
Time (hours) Distance (km)
2
190
4
380
5
475
The rate of Train A is 160|
km per hour.
The rate of Train Bis
km per hour.
Train (select)
is going faster.

Answers

Answer:

Train B is going faster than Train A

Step-by-step explanation:

The distance travelled by Train A, d = 80t

The distance travelled by Train B is given as follows;

Time (hours)  [tex]{}[/tex]                     Distance (km)

2                   [tex]{}[/tex]                         190

4                   [tex]{}[/tex]                         380

5                   [tex]{}[/tex]                         475

Therefore, we have that the rate of change of Train B is given as follows;

(475 - 380)/(5 - 4) = 95 km/h

(475 - 190)/(5 - 2) = 95 km/h

The rate of change of Train B = 95 km/h

While the distance covered by Train A per 1 hour, t = 1 is given as follows

Distance covered in 1 hour for Train A, d = 80 ×  1 = 80 kilometers

The rate of train A = Distance covered/(Time in which the distance was covered)

The rate of train of change A = 80 km/(1 hour) = 80 km/hour

The rate of train of change A = 80 km/h

Therefore, Train B is going faster than Train A.

Graph the equation y=x^2-8x+7y=x on the accompanying set of axes. You must plot 5 points including the roots and the vertex.
what points do i need to plot on the graph from this equation please hurry brainlest for whoever can help and 20 points

Answers

Answer: If you're plotting 1 equation (y=x^2-8x):

(-4,16) Vertex

(0,0) root

(8,0) root

If plotting both (y=x^2-8x) & (7y=x):

(-4,16) Vertex

(0,0) root

(8,0) root

(7,1) point on line

(-7, -1) point on line

Step-by-step explanation:

The vertex of the parabolic equation y = x² - 8x + 7 will be at (4, -9).

Now, Let the point (h, k) be the vertex of the parabola and a be the leading coefficient.

Then the equation of the parabola will be given as,

y = a(x - h)² + k

The equation is given below.

y = x² - 8x + 7

Convert the equation into a vertex form. Then we have

y = x² - 8x + 7

y = x² - 8x + 16 - 16 + 7

y = (x - 4)² - 9

Hence, The vertex of the parabolic equation y = x² - 8x + 7 will be at

(4, -9).

So, The graph is given below.

More about the equation of the parabola link is given below.

The expression (3)(4)(-3/4) is equivalent to -9.

None of the given options is correct.

Given information:

The expression is (3) (4) (-3/4).

Multiplying 3, 4, and -3/4, we get:

(3)(4)(-3/4),

Simplify the parenthesis,

2. Not only is the mean of pairs of clothes purchased is 10, but the population standard deviation is 4.5. When the researcher from problem number 1 calculates a standard deviation for the distribution of sample means for her 2,950, 000 samples, is the standard deviation of sample means likely to be less than, greater than, or equal to 4.5? Explain

Answers

Answer:

Less than 4.5

Step-by-step explanation:

Given that :

Mean = 10

Population standard deviation (σ) = 4.5

Sample size (n) = 2950000

The standard deviation of sample means becomes smaller or lesser as the sample size increases according to the central limit theorem. This is because the standard deviation of sample means is obtained by dividing the population standard deviation by the square root of the sample size. Thus is called the standard error.

The standard deviation of sample means is called the standard error ; and is obtained by:

Standard Error = σ/√n

Standard Error = 4.5 / √2950000

Standard Error = 4.5 / 1717.5564

= 0.0026200

There could be only two terms, and there could be one hundred, thousand. There seem to be summations with an infinite number of representatives.

On another hand, an isosceles triangle is a triangle in which any two sides or angles will be the same.

Hence given that the triangle has

Angle first = 70°

Angle second = 70° since there are two angles same so there will also be two sides equal so it will be an isosceles triangle.
