By comparing the fractions, we see that 7/9 is larger than 5/8, thus, Jamal has the better record.

We know that Jamal made 7/9 of his free throws while Brian made 5/8 of his free throws.

To see which player has the better record, we need to see which one of the two fractions is larger.

To do so we can write both of the fractions as decimals, we will get:

7/9 = 0.77...

5/8  =0.625

There we can see that 7/9 is larger, thus, we can conclude that Jamal has a better record.

When counting the number of successes in n trials, the (D) binomial distribution should be used if the success probability, p, stays constant from trial to trial.

As it is given in the descrip[tion itself that the probability of observing a specific number of successful outcomes in a specific number of trials is determined by the binomial distribution.

Therefore, when counting the number of successes in n trials, the (D) binomial distribution should be used if the success probability, p, stays constant from trial to trial.

The inequalities that model each situation are given as follows:

a. w ≤ 20, meaning that vehicles with two axles can weight at most 20 tons.

b. w ≤ 30, meaning that vehicles with three axles can weight at most 30 tons.

c. w ≤ 40, meaning that vehicles with four axles can weight at most 40 tons.

In each inequality, the plotted numbers are the numbers to the left, with a closed circle, hence:

In item a, we have that for vehicles with 2 axles, the upper weight limit is of 20 tons, hence the inequality is:

w ≤ 20.

In item b, we have that for vehicles with 3 axles, the upper weight limit is of 30 tons, hence the inequality is:

w ≤ 30.

In item c, we have that for vehicles with 4 axles, the upper weight limit is of 40 tons, hence the inequality is:

Answer:x=-13+1/5

Step-by-step explanation:

10x-18=15x+48

We move all terms to the left:

10x-18-(15x+48)=0

We get rid of parentheses

10x-15x-48-18=0

We add all the numbers together, and all the variables

-5x-66=0

We move all terms containing x to the left, all other terms to the right

-5x=66

x=66/-5

x=-13+1/5

The degree measure of one angle of a 30 sided regular polygon is 168°​

A two-dimensional geometric shape with a finite number of sides is called a polygon. A polygon's sides or edges are made up of segments of straight lines that are joined end to end to create a closed shape.

The intersection of two lines is referred to as a vertex or corner, and an angle is created as a result. Regular polygons are those that have sides that are congruent.

We will use the side-angle relation of a regular polygon with any no. of sides to find total sum of interior angles that is

(Side - 2) × 180°

(30 - 2) × 180°

= 5040°

Measure of each angle of 30-gon

= 5040°/30

= 168°​

Thus, the degree measure measure of One angle of a 30 sided regular polygon is 168°​

If your train travels at 65 miles per hour for 3.5 hours, it go 227.5 miles.

What is Speed ?

Velocity is the pace and direction of an object's movement, whereas speed is the time rate at which an object is travelling along a path. In other words, velocity is a vector, whereas speed is a scalar value.

Given:

Speed S = 65 miles per hour

Time T = 3.5 hours

We know that,

S= D/T  Where D is the distance traveled.

Therefore,

65 miles per hour = D/ 3.5 hours

D = 65 x 3.5 miles

=227.5 miles

The range for both groups are the same, therefore: C. The variability in students’ heights of both groups is the same.

To find the mean of a data set, sum all data points given together and divide what you get by the number of data points that is given in the data set.

The range of a data gives us an idea of the spread of a data, which is a measure of variability. The larger the range, the more the variability that exist in the data set.

Given, Group A: 51, 53, 60, 64, 55, and Group B: 50, 55, 58, 63, 52, find the mean of each data set

Mean for Group A = (51 + 53 + 60 + 64 + 55)/5 = 283/5 = 56.6

Mean for Group B = (50 + 55 + 58 + 63 + 52)/5 = 278/5 = 55.6

Range for Group A = 64 - 51 = 13

Range for Group B = 63 - 50 = 13

This means that variability in students’ heights is the same for both group A and B.

3)a) The angles are congruent by alternate interior angles postulate.

b) The angles are congruent by linear pairs postulate.

c) The angles are congruent by corresponding angles postulate.

When two parallel lines are intersected by a third one, the angles that occupy the same relative position at each intersection are known to be corresponding angles to each other.

1) From definition of corresponding angles, line m is parallel to line n and as such, we can say that;

2x + 12 = 38

2x = 38 - 12

2x = 26

x = 13

2) From definition of corresponding angles, line m is parallel to line n and as such, we can say that;

3x + 41 = 8x - 29

8x - 3x = 41 + 29

5x = 70

x = 14

3) a) From definition of alternate interior angles, we can say that yes the angles are congruent by alternate interior angles postulate.

b) Linear pair of angles are formed when two lines intersect each other at a single point. Thus, the angles are supplementary and add up to 180° and they are congruent by linear pairs postulate.

Line A is perpendicular to D because a is parallel to c and c is perpendicular to d.

Parallel lines have the same slope since the slope is like a measure of steepness and since parallel lines are of the same steepness, thus, are of the same slope. Since the given parallel line has equation y = 2x + 2, thus its slope is 2 and thus, the slope of the needed line is 2 too.

WE have been given that a ll b,b ll c,c is perpendicular to d.

Here the line a is parallel to b and b is parallel to c so a must be parallel to c.

As we know that c is perpendicular to d since, a is parallel to c.

Therefore, Line A is perpendicular to D because a is parallel to c and c is perpendicular to d.

Considering when a triangle is formed given three sides, the code for the puzzle is given as follows:

BBBACC

In a triangle, the sum of the lengths of the two smaller sides of the triangle has to be greater than the length of the greater side of the triangle.

For the first letter, we have two sides, hence there are many possible values for the third side x, as long as 2.5 + x > 8, for x < 8 or x < 10.5, for x > 8, hence the first letter of the code is of B.

For the second letter, 4 + 7 < 19, hence no triangle can be formed with these dimensions and the letter is of B.

For the third letter, 2 + 4 > 5, hence one unique triangle can be formed with all the dimensions given and the letter is of B.

For the fourth letter, 6 + 8 > 12, hence one unique triangle can be formed with all the dimensions given and the letter is of A.

For the fifth letter, we have two sides, hence there are many possible values for the third side x, as long as 1 + x > 2.4, for x < 2.4 or x < 3.4, for x > 2.4, hence the letter is of C.

For the sixth letter, 5 + 9 > 13, hence one unique triangle can be formed with all the dimensions given and the letter is of C.

Answer: their difference in elevation is 188 feet

Step-by-step explanation:

The derivative of f(x) = (1 - 3x)^(1/3) is  f'(x) = - (1 - 3x)^(-2/3). The  *(-3) comes from the derivative of (1 - 3x) with respect to x, due to the chain rule.

Chain rule:  dy/dx = dy/du. du/dx

Suppose we have f(g(x)), then its derivative is: f'(g(x)) . g'(x)

In the problem:

f(x) = (1 - 3x)^(1/3)

Let u = 1 - 3x

then f(u) = u^(1/3)

and f'(u) = 1/3 u^(-2/3)

That part only the derivative of f with respect to u. We still need to take the derivative of u with respect to x. That is:

u(x) = 1 - 3x

u'(x) = -3

Hence, the complete derivative is:

f'(x) = f'(u) . u'(x)

     = 1/3 u^(-2/3) . (-3)

     = -  u^(-2/3)    ( substitute back u = 1 - 3x )

     = - (1 - 3x)^(-2/3)

Hence the *(-3) comes from the derivative of (1 - 3x) with respect to x, due to the chain rule.
