Answer:

C. -1/2, 2, √5, √16, 4,05

Step-by-step explanation:

When ordering numbers from least to greatest first comes negative values then we compare all positive expressions

2 is smaller than √5 because it's approximately 2.2 and then comes √16 because it's equal to 4 and finally comes 4.05

Answer:

C

Step-by-step explanation:

Dividing zero by any value gives a result of zero, thus

[tex]\frac{0}{7}[/tex] = 0 → C

Answer:

C. 0

Step-by-step explanation:

0/7.  It means 7 divided by 0, which is 0.  

But if it was 7/0, it would be undefined.

7/0= undefined

0/7= 0

The answer is c, 0.  :)

Explanation:

There is only one way to get a sum of 18 and that is rolling three '6's to get 6+6+6 = 18.

There are 6*6*6 = 216 different ways to roll three dice.

Divide the two values to get 1/216

Answer:

8

Step-by-step explanation:

think about this: which number has the bigger distance from 0 on a number line.

-4  -3  -2  -1  0  1  2  3  4  5  6  7  8

You can see the distance between -4 and 8. Because 8 is eight spaces away from zero, and -4 is 4 spaces away from zero, we can see that 8 is bigger

The 8 is greater than -4. The difference between the two numbers is 12, and 8 is a positive number, while -4 is a negative number, solidifying that 8 is the larger value.

To compare the numbers -4 and 8, we can use the number line or basic numerical comparison. On the number line, -4 is to the left of 8, indicating that 8 is greater. Additionally, we can verify this by subtracting -4 from 8, which gives us 12 (8 - (-4) = 12). Since 12 is positive, 8 is indeed greater than -4.

In numerical comparison, when a positive number is compared to a negative number, the positive number is always greater. This is because negative numbers are "less than" zero, and positive numbers are "greater than" zero.

In conclusion, 8 is greater than -4. The difference between the two numbers is 12, and 8 is a positive number, while -4 is a negative number, solidifying that 8 is the larger value.

Answer:

The next step of the construction is;

Place the compass at point N and adjust the width to the point where the arc crosses the other side leg of the angle

Step-by-step explanation:

The steps to copy an angle are;

1) Mark the point C of the vertex of the new angle

2) Draw a ray from C in the desired direction

3) With the compass placed at M of the original angle, draw an arc that crosses both sides of the original angle. Mark the crossing points N and O

4) With the same compass width from the arc drawn in the above step, draw a similar arc that crosses the ray from C at point D

5) Place the compass at point N and adjust the width to point O, the point where the arc crosses the other side of the angle

6) While the adjusted compass width is held to remain the same, place the compass at point D and draw an arc to cross the previous arc drawn from C and label the intersection point E

7) With the straight edge, draw a ray FC that passes through E to point C to complete the copied angle.

Step-by-step explanation:

(1) The range of set A is greater than the range of set B.

This statement  gives only the range which means only outermost values but what about the other values. For example-11,0,0,0,11 and -10,-10,0,10,10

Clearly, Former one has higher range but lower standard deviation.

(2) Sets A and B are both evenly spaced sets.

Evenly spaced is fine. However, we don't know the spacing since that is required to know the deviation.

For, example, sets A{2,4,6,8,10} and B {1,2,3,4,5} so in this case SD of A> SD of B. Or,  we can have B{2,4,6,8,10} and A{1,2,3,4,5} so in this case SD of B> SD of A.

The graph of a linear equation is a straight line.

The graph has a positive slope and it passes through the origin

The given parameters are:

[tex]\mathbf{m =\frac 23}[/tex]

[tex]\mathbf{(x,y)= (0,0)}[/tex]

A linear equation is represented as:

[tex]\mathbf{y = mx + b}[/tex]

[tex]\mathbf{m =\frac 23}[/tex]

So, we have:

[tex]\mathbf{y = \frac 23 x + b}[/tex]

[tex]\mathbf{(x,y)= (0,0)}[/tex] represents the y-intercept (i.e. b = 0).

So, we have:

[tex]\mathbf{y = \frac 23 x + 0}[/tex]

[tex]\mathbf{y = \frac 23 x}[/tex]

See attachment for the graph of [tex]\mathbf{y = \frac 23 x}[/tex]

The slope of the line through the points is -5/7

Step-by-step explanation:

Here, we want to calculate the value of the slope through the lines

Mathematically;

m = y2-y1/(x2-x1)

Where (x1,y1) = (-4,2)

and (x2,y2) = (3,-3)

Substituting these values, we have;

m = (-3-2)/(3-(-4)) = -5/7 = -5/7

Answer: Mean get decreased and median remains same.

Step-by-step explanation:

Given: The low scores of all 4 friends  are all between 90 and 100, except for Angie, whose low score is 80.

i.e. Angie is an outlier.

[An outlier is an extreme value which lies far from the other data values.]

Angie then golfs a great round and has a new low score of 75.

i.e. more lower value.

Since Mean gets effected by an outlier but median remains same.

Here, value of new outlier(75) is less than the previous one (80), so mean score will get decreased, where as median (middle most value in ordered data) remains the same.

Answer:

[tex]8\sqrt{2}[/tex]

Step-by-step explanation:

Step 1: Use Pythagorean Theorem to find the length of the hypotenuse

[tex]a^{2}+b^{2} =c^{2}[/tex]

[tex]9^{2}+7^{2} =c^{2}[/tex]

[tex]81+47 =c^{2}[/tex]

[tex]128 =c^{2}[/tex]

[tex]\sqrt{c^{2} } =\sqrt{128}[/tex]

[tex]c=\sqrt{128}[/tex][tex]\sqrt{128} =8\sqrt{2}[/tex]

Therefore the third side is [tex]8\sqrt{2}[/tex]

Answer:

The slope is 0.

Step-by-step explanation:

To find the slope, we can do (7 - 7) / (12 - 3) = 0 / 9 = 0. This makes sense because if we look at the points, they both have the same y-coordinate, so we know that as x increases / decreases, y never changes. Because y never changes, the slope is 0.

Answer:

m=0

Step-by-step explanation:

To find slope, it is y2-y1/x2-x1

Therefore, x1=3, x2=12, y1=7 and y2=8

Plugging those variables in,

(7-7)/(12-3)=

7-7=0

12-3=9

0/9=0

Therefore, slope of the line that passes through points (3,7) and (12,7) is 0

Answer:

A

Step-by-step explanation:

The secant- tangent angle 50° is half the difference of the measures of the intercepted arcs, that is

[tex]\frac{1}{2}[/tex](210 - x) = 50 ( multiply both sides by 2 )

210 - x = 100 ( subtract 210 from both sides )

- x = - 110 ( multiply both sides by - 1 )

x = 110°

The sum of the 3 arcs on the circle = 360°

210 + x + z = 360

210 + 110 + z = 360

320 + z = 360 ( subtract 320 from both sides )

z = 40°
