You're looking at a bar graph and see numbers going from the bottom to the top from 0 to 100 which of the following are you looking at?

A. Horizontal scale
B. Vertical scale
C. Horizontal label
D. Vertical label

Answer:

50/77

Step-by-step explanation:

(1÷2 3/4)+(1÷3 1/2)

2 3/4 is same as 11/44

1/2 is same as 7/2

so to divide fraction you have to flip the second number and multiply

so 1 times 4/11=4/11

and 1 times 2/7=2/7

4/11 +2/7=28/77+22/77=50/77

The empirical rule indicates that we can expect to find approximately 68% of the sample included between x - s and x + s.

The empirical rule, also known as the 68-95-99.7 rule, is a statistical rule that applies to data that is approximately normally distributed. According to this rule:

About 68% of the data falls within one standard deviation (s) of the mean (x).

About 95% of the data falls within two standard deviations of the mean.

About 99.7% of the data falls within three standard deviations of the mean.

Therefore, if we have a sample that is approximately normally distributed, we can expect to find approximately 68% of the sample included between x - s and x + s.

To clarify, this means that if we take all the data points in the sample, and we calculate the mean (x) and standard deviation (s), then approximately 68% of the data points will fall within one standard deviation of the mean in either direction.

The equation of the line passing through (1, 1) and and with -1 as y-intercept is is 2x - y - 1 = 0..

The equation of line in general form is expressed as:

Ax + Bx + C = 0.

From the graph, the line passes through points (0,-1) and (1,1).

First we determine the slope of the line:

\(m = \frac{y_2 - y_1}{x_2 - x_1} \\\\m = \frac{1 - (-1) }{1 - 0} \\\\m = \frac{1 + 1 }{1 - 0} \\\\m = \frac{ 2 }{1 } \\\\m = 2\)

Next, we can choose either of the given points to substitute into the point-slope form.

Point (0, -1) and slope 2:

y - y₁ = m(x - x₁)

y - (-1) = 2(x - 0)

y + 1 = 2x

y = 2x - 1

Now, we express the equation in general form (Ax + By + C = 0), we move all terms to one side:

2x - y - 1 = 0

Therefore, the equation of the line in general form is 2x - y - 1 = 0.

Answer:

(-f+v) = -13i-15j

Step-by-step explanation:

Given that,

Vector f = (10,5) = 10i+5j

Vector v = (-3,-10) = -3i-10j

We need to find (-f+v).

Let x = (-f+v)

Plug all the values,

x = [-(10i+5j) + -3i-10j]

= (-10i-3i)+(-5j-10j)

= -13i-15j

Hence, (-f+v) = -13i-15j

Answer:

D; 85 leaves

Step-by-step explanation:

From what we can see, each 4 days there is a growth of an additional 9 leaves

So for the 20th day, we can see 58

The difference between the 20th and 32nd day is 12

The number of 4s we can see here is 12/4 = 3

For each 4, we can count extra 9 leaves

So for the 12, the number of leaves we can count is 3 * 9 = 27

we proceed to add this to 58

That will yield 58 + 27 = 85

Answer:

y + 2 = 3/4 (x - 1)

Step-by-step explanation:

You would pick one of the points in this case I picked (1, -2), for point-slope form your equation is y - y1 = m(x-x1).

Finding the slope (m) is easy you just do rise (up/down) OVER run (left/right).

So in this case your slope (m) is 3/4.

then you just plug everything in but because two negatives equal a positive you equasion should look like this y + 2 = 3/4(x - 1)

In order to fill the ice cream cone of the above mentioned dimensions of ice cream cone in the question  5 ice cream scoops are required.

The number of ice cream scoops that are needed to fill an ice cream cone with radius 2 inches and height 5 inches given that the ice cream scoop scoops out ice cream spheres with radius 1 inch can be calculated as follows: Volume of an ice cream cone is given by: V = (1/3)πr²hwhere r = radius and h = height of the cone, Radius of the ice cream cone, r = 2 inches, Height of the ice cream cone, h = 5 inches. Volume of the ice cream cone, V = (1/3)πr²h= (1/3) x (22/7) x 2² x 5= 20.95 cubic inches. The volume of a sphere is given by: V = (4/3)πr³where r = radius of the sphere.Radius of the ice cream sphere, r = 1 inch. Volume of the ice cream sphere, V = (4/3)πr³= (4/3) x (22/7) x 1³= 4.19 cubic inches.

Therefore, the number of ice cream scoops needed to fill the ice cream cone is given by: Number of scoops = Volume of the ice cream cone/Volume of the ice cream scoop= 20.95/4.19= 5 scoops. Hence, 5 ice cream scoops are required to fill the ice cream cone with radius 2 inches and height 5 inches.

The length of AB is 12 units. The two smaller triangles formed, namely ABD and BCD, are similar to the original triangle ABC.

In a right triangle ABC, with the altitude BD drawn to the hypotenuse AC, we can use the property of similar triangles to find the length of AB.Let x be the length of AB. Since the triangles ABD and ABC are similar, we can set up a proportion:

AB/AD = AC/AB+BC

Substituting the given values, we have:

x/12 = 27/(x + BC)

Cross-multiplying, we get:

27x = 12(x + BC)

Simplifying further:

27x = 12x + 12BC

Combining like terms:

15x = 12BC

Dividing both sides by 15:

x = (12/15)BC

Since BD is the altitude, we know that BD + DC = AC. Substituting the values:

12 + BC = 27

Simplifying:

BC = 15

Substituting BC = 15 back into the equation for x, we find:

x = (12/15)(15)

x = 12

The slope of the line that joins the points is negative.

i.e m = -6/5

Step-by-step explanation:

Taking two points from the graph to determine the slope

Finding the slope between (-3, 4),(2, -2)

\(\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}\)'

\(\left(x_1,\:y_1\right)=\left(-3,\:4\right),\:\left(x_2,\:y_2\right)=\left(2,\:-2\right)\)

AB ≠ I and BA ≠ I, the two matrices are not inverses of each other.

To check if two matrices are inverses of each other, we can multiply them and see if we get the identity matrix.

Let A be the first matrix and B be the second matrix. Then, the product of A and B is:

AB = 10(0) + 1(-1) 10(1) + 1(10)

(-1)(0) + 0(1) (-1)(1) + 0(10)

= -1 11

0 -1

Similarly, the product of B and A is:

BA = 0(10) + 1(-1) 0(1) + 1(10)

(-1)(0) + 10(1) (-1)(1) + 10(0)

The measure of an exterior angle of triangle equals the sum of the measures of its two remote interior angles.

The angle measuring 12x + 14 is an exterior angle of the triangle.

The angles measuring 76 deg and 1 + 5x are its remote interior angles.

12x + 14 = 1 + 5x + 76

The average rate of change in the population in each state between 1970 and 2010 is given as follows:

The average rate of change of a function is given by the change in the output of the function divided by the change in the input of the function. Hence, over an interval [a,b], the rate is given by the fraction presented as follows

\(r = \frac{f(b) - f(a)}{b - a}\)

For California, the populations are given as follows:

Hence the rate is:

r = (35 - 20)/(2010 - 1970) = 0.375 million people a year = 375,000 people a year.

Answer:

d. Missing x:2 Missing y:5

Step-by-step explanation:

To determine the missing data values, we need to first determine the equation of the linear function that represents the given data. We can use the two given data points (x=0, y=3) and (x=-1, y=2) to find the slope of the function:

slope = (y2 - y1) / (x2 - x1) = (2 - 3) / (-1 - 0) = -1

Next, we can use the point-slope form of a linear equation to find the y-intercept of the function:

y - y1 = m(x - x1)

y - 3 = -1(x - 0)

y - 3 = -x

y = -x + 3

Using this equation, we can determine the missing data values:

When x=4, y = -4 + 3 = -1.

When x=2, y = -2 + 3 = 1.

Therefore, the correct option is:

d. Missing x:2 Missing y:5

Pete scored higher than 730 of the 1000 students who took the standardized test.

Pete's score of 63 means that 73% of students who took the standardized test scored lower than Pete. This can be expressed mathematically as:

Pete's Percentile Rank = \(# of Students Scoring Lower than Pete / Total # of Students * 100 = 73%.\)

This calculation can also be expressed as:

Students Scoring Lower than Pete = Total no of Students * Percentage Rank

= 1000 * 0.73 = 730.

Therefore, Pete scored higher than 730 of the 1000 students who took the standardized test.

The basketball player made 10 two-point shots and 7 free throws.

To find the number of two-point shots made by the basketball player, we need to divide the total number of points scored by 2 (since each two-point shot is worth 2 points).

So, to find the number of two-point shots, we divide the total points (21) by 2:
21 / 2 = 10.5

Since we cannot have half a shot, we round down to the nearest whole number.

Therefore, the basketball player made 10 two-point shots during the game.

To find the number of free throws made, we subtract the number of two-point shots from the total number of scores.

So, to find the number of free throws, we subtract 10 from 17:
17 - 10 = 7

Therefore, the basketball player made 7 free throws during the game.

In summary:
- The basketball player made 10 two-point shots.
- The basketball player made 7 free throws.
