The coordinate 2 has a weight of 2,

the coordinate 3 has a weight of 2,

and the coordinate 10 has a weight of 1.

Find the weighted average.

Answers

Answer 1

The coordinates' weighted average is 4

How is the weight average calculated?The "weighted average" is the average of a group of numbers, each of which has a unique "weight" or value. Add the results after dividing each number by its weight to obtain the weighted average. A weighted average or mean is one in which, as opposed to considering each item equally, each item being averaged is multiplied by a number (weight) based on the item's relative importance.

The given parameters are:

Coordinate 2 has a weight of 2

Coordinate 3 has a weight of 2

Coordinate 10 has a weight of 1

The weight average is then calculated as:

Weight average = Sum of (Weight * Coordinate)/Sum of Weights

So, we have:

Weight average = (2 × 2 + 3 ×2 + 10 × 1)/(2 + 2 + 1)

Evaluate the quotient

Weight average = 4

Hence, the weight average of the coordinates is 4.

The equation of the axis of symmetry is x = 7

Step-by-step explanation:

Mathematically, we have the equation of the axis of symmetry as;

x = -b/2a

where a is the coefficient of x^2 = 1

b is the coefficient of x which is -14

So, the equation of the axis of symmetry will be;

x = -(-14)/2(1) = 14/2 = 7

So the equation of the axis of symmetry is x =7

A bus traveled 330 miles between two cities. If the bus traveled for 6 hours, how
many miles did the bus travel per hour?

Answers

Answer:

55 miles per hour

Step-by-step explanation:

.......ur welcome.......

330÷6=55

we divide the amount of miles by the time it took the bust to travel

A bus traveled 330 miles between two cities. If the bus traveled for 6 hours,, The bus will travel  approximately 55 miles per hour.

To determine the number of miles the bus traveled per hour, we need to divide the total distance traveled by the time taken.

Given:

Total distance traveled = 330 miles

Time taken = 6 hours

To find the miles per hour, we divide the total distance traveled by the time taken:

Miles per hour = Total distance traveled / Time taken

Miles per hour = 330 miles / 6 hours

Miles per hour ≈ 55 miles per hour

Therefore, the bus traveled approximately 55 miles per hour.

Use both the first and second derivative tests to show that f(x) = 3x2 − 6x + 1 has a relative minimum at x=1.

Answers

Step-by-step explanation:

Given: f(x) = 3x^2 − 6x + 1.      x ∈ (-∞, ∞)

now differentiating f(x) w.r.t. x we get

f'(x) = 6x-6

equating it 0 we get

x = 1, which is a critical point

Now using second derivative test to check relative maxima or minima

f''(x) = 6 >0

⇒ x=1 is a relative minima.

also, x=1 f(1) = 3-6+1 = -2

please help me solve for x and find missing side lengths and angle measures,,

Answers

Answer: 90

Step-by-step explanatio

Answer:

the angle measure for angles T and V would be 127 because they are on opposite locations from each other. the angles S and U would 53 because T and U are coplemantery angles (180 degrees) so you subtract. 180-127 to get 53. To find x, on angle S, we simply subtract 1 from 53 (53-1) and divide the answer by 2. To find the lengths of the sides, put them next to each other and separet

them by an equal sign. subtract 3y from both sides of the equation and add 5 to both sides of the equation to get 3y=12. then divide 12 by 3 to get 4 so y=4. Then, simply replace the y with a 4 and solve the equations of the sides.

Alex records the running time—the number of minutes a movie lasts from start to finish—of 50 popular movies. The distribution of times, in minutes, is displayed in the histogram below.

Answers

Answer:

You forgot to attach the question and the histogram.

Is your question “the interval containing the most movies” ? If yes, then the answer is :

Interval 90-100 minutes

Step-by-step explanation:

A histogram is a chart that is used to represent data in form of bars.

Like every other chart, it consists of both the x and y axis. The y axis contains the frequency or percentage of occurrences while the x axis contains the range or intervals.

To determine the interval with the most occurrences, that is the interval containing most movies, we look for the bar with the most height. The bar that is tallest amongst others has the most movies in its running time.

From the attached histogram, the interval containing the most movies is the 90- 100 minutes interval.

This simply means that from Alex’s record, out of the 50 popular movies, more movies run with the 90-100 minutes interval.

PS: view the attached histogram
