Find the distance (-2,4) and (-5,-0)

===========================================

Convert each fraction shown to decimal form

With the exception of 7/16 = 0.43750, the other decimal values are approximate.

From that list, we can see the decimal representations of 7/16, 8/15, and 6/11 are all smaller than the decimal version of 5/9. So we rule out choices A, B, and C. The answer must be choice D.

Sure enough, 14/23 = 0.60870 is indeed larger than 5/9 = 0.55555

---------------------

We can show this another way:

First off, assume that 14/23 and 5/9 are equal. We'll cross multiply and show a contradiction happens

14/23 = 5/9

14*9 = 23*5

126 = 115

The contradiction happens since we should get the same value on both sides if the two sides were equal, but they're not equal.

If we replace each equal sign with a greater than sign, then we get,

14/23 > 5/9

14*9 > 23*5

126 > 115

You can think of it like working backwards up the chain.

Answer:

Following are the solution to the given points:

Step-by-step explanation:

Both A and B are exclusive to each other because of P(A and B) = 0.

Therefore, Let A be the major in mathematics and B be the major in philosophy.

Each student is required to only have one major.

No student does have two significant students.

Therefore, the likelihood of both the major pupils being zero.

This is P(A and B) = zero

Therefore, The events are exclusive to each other.

Step-by-step explanation:

~ Hope this helped u Kaitilyn :)))))

Answer:

11/26 is red, 10/26 is yellow, and 5/26 is blue

Step-by-step explanation:

So, to find the probabilities, we must figure out the total amount of frequency found. To do this lets add up the frequencies of red blue and yellow:

11+10+5 = 26

So our total is 26.

This will be the denominator of our fractions. The numerator will be the amount of the specific freuqency we are looking at.

So reds would be:

11/26 - Frequency of red over Total frequency = Ratio

10/26 - Frequency of red over Total frequency = Ratio

5/26 - Frequency of red over Total frequency = Ratio

So these are your 3 answers!

Hope this helps!

8 columns bar graph.

Step-by-step explanation:

$2 = pen

$3 = notebook

This could be written as a bar graph in multiples of $6.00 along y axes.

3 pens + 8 notebooks. Then 12 pens + 2 notebooks.

Then 9 pens + 4 notebooks . Then 6 pens + 6 notebooks

3p + 8n,    12p + 2n,    9p+4n,    6p + 6n

3p = $6

8n = $24

12p = $24

2n = $6

Answer:

(910.053 ; 959.947)

Pvalue = 0.00596

Step-by-step explanation:

Given :

Population mean, μ = 900

Sample size, n = 200

Population standard deviation, σ = 180

The hypothesis :

H0 : μ = 900

H0 : μ ≠ 900

The 95% confidence interval:

Xbar ± Margin of error

Margin of Error = Zcritical * σ/√n

Since the σ is known, we use the z- distribution

Zcritical at 95% confidence = 1.96

Hence,

Margin of Error = 1.96 * 180/√200

Margin of Error = 24.947

95% confidence interval is :

935 ± 24.947

Lower boundary = 935 - 24.947 = 910.053

Upper boundary = 935 + 24.947 = 959.947

(910.053 ; 959.947)

Hypothesis test :

Test statistic

(935- 900) ÷ (180/√(200))

Test statistic = 2.750

Pvalue from Test statistic ;

Pvalue = 0.00596

Pvalue < α ; Reject H0 and conclude that score has changed

Hence, we can conclude that the score has changed

Answer:

The volume of the cube is decreasing at a rate of 63.1071 cubic millimeters per minute.

Step-by-step explanation:

The volume of a cube is given by:

[tex]V=s^3[/tex]

Implicitly differentiate the equation with respect to time t:

[tex]\displaystyle \frac{dV}{dt}=3s^2\frac{ds}{dt}[/tex]

The edge of the cube decreases by 0.53 mm/min. Therefore, ds/dt = -0.53.

When the edge is 6.3 mm, s = 6.3.

Substitute and evaluate:

[tex]\displaystyle \frac{dV}{dt}=3(6.3)^2\left(-0.53\right)=-63.1071\text{ mm}^3/\text{min}[/tex]

The volume of the cube is decreasing at a rate of 63.1071 cubic millimeters per minute.

Answer:

a. [tex]\frac{dy}{dt} = -\frac{13}{8}[/tex]

b. [tex]\frac{dx}{dt} = \frac{9}{2}[/tex]

Step-by-step explanation:

To solve this question, we apply implicit differentiation.

xy = 2

Applying the implicit differentiation:

[tex]y\frac{dx}{dt} + x\frac{dy}{dt} = \frac{d}{dt}(2)[/tex]

[tex]y\frac{dx}{dt} + x\frac{dy}{dt} = 0[/tex]

a. Find dy/dt, when x = 4, given that dx/dt = 13.

x = 4

So

[tex]xy = 2[/tex]

[tex]4y = 2[/tex]

[tex]y = \frac{2}{4} = \frac{1}{2}[/tex]

Then

[tex]y\frac{dx}{dt} + x\frac{dy}{dt} = 0[/tex]

[tex]\frac{1}{2}(13) + 4\frac{dy}{dt} = 0[/tex]

[tex]4\frac{dy}{dt} = -\frac{13}{2}[/tex]

[tex]\frac{dy}{dt} = -\frac{13}{8}[/tex]

b. Find dx/dt, when x = 1, given that dy/dt = -9.

x = 1

So

[tex]xy = 2[/tex]

[tex]y = 2[/tex]

Then

[tex]y\frac{dx}{dt} + x\frac{dy}{dt} = 0[/tex]

[tex]2\frac{dx}{dt} - 9 = 0[/tex]

[tex]2\frac{dx}{dt} = 9[/tex]

[tex]\frac{dx}{dt} = \frac{9}{2}[/tex]

Answer:

There is significant preference among the 3 designs

Step-by-step explanation:

Given :

Design 1 Design 2 Design 3

54 38 28

H0 : no significant preference among the 3 designs

H1 : The preference among the designs are different

To test, we use the Chisquare test for independence ;

χ² = (observed - Expected)² / Expected

The sample size, n = 120

Expected = 120 / number of designs = 120 / 3 = 40

(54-40)^2/ 40 + (38 - 40)² / 40 + (28 - 40)² / 40

= 4.9 + 0.1 + 3.6

= 8.6

The Chisquare critical value at 95% = 5.99

Since ;

|χ² critical| < χ² statistic ; we reject the null and conclude that there is significant preference among the 3 designs

Answer:

The answer is D. Translate vertex A to Vertex D, and then rotate triangleABC around point A to align the sides and angles

Translating vertex A to vertex D, and then rotate △ABC around point A to align the sides and angles will bring about a rigid transformation, the correct answer is D.

The transformations that preserves the Euclidean distance between points. This could be as a result of the any transformation.

Triangle ABC and DEF is shown,

Triangle A B C is rotated to the left about point A and then is shifted up and to the right to form triangle D E F.

To map ΔABC to ΔDEF , the  vertex A will be translated to vertex D, and then the triangle is rotated around point A.

This will maintain the distance between the points when vertex A to D.

Answer:

The reflection of the point (x, y) across the y-axis is the point (-x, y). When you reflect a point across the line y = x, the x-coordinate and the y-coordinate change places. Notice how each point of the original figure and its image are the same distance away from the line of reflection (x = –2 in this example).

Step-by-step explanation:

Answer:

the rotated point B is then at (3, -7)

Step-by-step explanation:

the specification says a rotation of -90 degrees (counter clockwise) around the point (0, 0).

a turn by 90 degrees in any direction brings it always into the next quadrant, because every quadrant represents 90 degrees.

the rotated point will have the same distance from the center, of course. and the angle of the connection line center to B to the negative x-axis will be then the same as the angle of the connection line to the rotated point to the negative y-axis.

just think about rotating the original graph by -90 degrees. point B stays on the grid were it is and moves with the grid, and we just flip the coordinate axis.

so, it will be (3, -7).

Answer:

A proof for the statement by selecting the given sentences are as follows;

Suppose there is an integer m such that 7·m + 4 is divisible by 7

By definition of divisibility, 7·m + 4 = 7·k for some integer k

Subtracting 7·m from both sides of the equation gives 4 = 7·k - 7·m = 7·(k - m)

Dividing both sides of the equation by 7 results in 4/7 = k - m

But k - m is an integer and 4/7 is not an integer

Therefore, for every integer m, 7·m + 4 is not divisible by 7

Step-by-step explanation:

The given equation can be expressed as follows;

Where 7·m + 4 is divisible by 7, we have;

7·m + 4 = 7·k

Where 'k' is an integer

We have;

7·m + 4 - 7·m = 4 = 7·k - 7·m

∴ k - m = 4/7, where k - m is an integer

∴ k - m cannot be equal to 4/7, from which we have;

7·m + 4 cannot be divisible by 7.
