Answer:

Equivalent

Step-by-step explanation:

A set is a well defined collection of objects.

Two sets are said to be equal if they have the same elements.

Two sets are said to be equivalent if they have the same number of elements.

Given sets are [tex]\{0,9\}\,,\,\{8,1\}[/tex]

These sets are not equal as both the sets have different elements.

Order of both the sets is 2 (number of elements in both sets is 2)

So,

these two sets are equivalent.

Answer:

¾

Step-by-step explanation:

The line that slants upward from left to right is a positive slope, while the line that slants downwards from left to right is a negative slope.

Therefore, the blue line would have a positive slope. Since the blue line with a positive slope is perpendicular to the red line with a negative slope, therefore, the slope of the line with a positive slope that we are looking for and that is perpendicular to one of the lines (red line) would be the same with the slope of the blue line.

The slope of the blue line is calculated as shown below:

Use the coordinates of these two points on the blue line to find the slope, (0, 1) and (4, 4)

[tex] slope(m) = \frac{y_2 - y_1}{x_2 - x_1} = \frac{4 - 1}{4 - 0} [/tex]

[tex] slope(m) = \frac{3}{4} [/tex]

The slope of the line we are looking for is ¾.

Answer:$94.50

Step-by-step explanation:5% of 50 is 2.5 and 5% of 40 is 2 so the math you would do is 50+40+2.5+2 which equals $94.50.

Answer:

The probability is  [tex]P(k) =0.07843[/tex]

Step-by-step explanation:

From the question we are told that

   The total number of cards is  n  =  52

Generally the number of ace in a standard deck of cards is  k  =  4

Generally the the first card drawn is not an ace so the remaining number of ace after the first card is drawn is  k =  4

also the remaining total number of cards after the first card is drawn is

     N =  n- 1

=>  N =  52 - 1  

=>  N =  51

Generally the probability of drawing an ace on the second attempt if the first card (which you did NOT put back in the pack) was not an ace is mathematically represented as

        [tex]P(k) =\frac{k}{N}[/tex]

=>      [tex]P(k) =\frac{4}{51}[/tex]

=>      [tex]P(k) =0.07843[/tex]

Answer:

[tex]MN = 8[/tex]

Step-by-step explanation:

Given

[tex]LM = 5\\MN = x - 4\\LN = 2x - 11[/tex]

Required

Determine MN

MN is calculated as thus:

[tex]LN = LM + MN[/tex]

Make MN the subject

[tex]MN = LN - LM[/tex]

Substitute values for MN, LN and LM

[tex]x - 4 = 2x - 11 - 5[/tex]

[tex]x - 4 = 2x - 16[/tex]

Collect Like Terms

[tex]x - 2x = -16 +4[/tex]

[tex]-x = -12[/tex]

[tex]x= 12[/tex]

Substitute 12 for x [tex]MN = x - 4[/tex]

[tex]MN = 12 - 4[/tex]

[tex]MN = 8[/tex]

Answer:

angle T = 114

Step-by-step explanation:

SRT = STR

angle R = angle T

angle R = 33°

so angle R and angle T = 33°

all angles on a triangle = 180°

so

angle R + angle S + angle T = 180°

and angle R and S = 33° so subtitute...

33 + 33 + T = 180

then solve:

66 + T = 180

-66         -66

T = 114

mathy way:

SRT = STR                 Given

SRT = 33                   Given

33 = STR                   Substitution Property of Equality

STR = 33                  

R + S + T = 180°        Deffinition of triangle

33 + 33 + T = 180     Substitution Property of Equality

66 + T = 180             Addition

T = 114                       Subtraction Property of Equality

whats the question?

Step-by-step explanation:

Answer:

a)Total amount of water in pool 1 after x minutes = 1850+27x

Total amount of water in pool 2 after x minutes = 1334+39x

b) an equation to show when the two pools would have the same amount of water is 1850+27x= 1334+39x

Step-by-step explanation:

First Pool :

Initial amount of water in Pool = 1850 liters

Water is being added to the first pool at a rate of 27 liters per minute.

Amount of water added after x minutes = 27x

So, Total amount of water after x minutes = 1850+27x

Second Pool:

Initial amount of water in Pool = 1334 liters

Water is being added to the first pool at a rate of 39 liters per minute.

Amount of water added after x minutes = 39x

So, Total amount of water after x minutes = 1334+39x

Now to find  an equation to show when the two pools would have the same amount of water.

1850+27x= 1334+39x

1850-1334=39x-27x

516=12x

[tex]\frac{516}{12}=x[/tex]

43 =x

Hence

a)Total amount of water in pool 1 after x minutes = 1850+27x

Total amount of water in pool 2 after x minutes = 1334+39x

b) an equation to show when the two pools would have the same amount of water is 1850+27x= 1334+39x

Answer:

x ∈ R ( 0 , + ∞ )

Step-by-step explanation:

In the function:

F(x) = 4*x -0,1*x²

The domain of  F(x) is all the set of real numbers

R ∈ ( -∞ , +∞ )

values for F(x), can be found from negative and positive values of x

for instance for:

x = -2          F(x) = 4*(-2) - 0,1 * (-2)²        F(x) = - 8,4

x = 2           F(x) = 4*(2) - 0,1 * (2)²           F(x) = 7,6

But distance x could not be negative ( there is not negative distance in the real world), therefore the reasonable range restricts values of x only to positive values.

Then x can be any number x ≥ 0  ( distance could be 0 )

Answer:

C) The limitation for the reasonable range restricts it to real numbers greater than or equal to 0 and less than or equal to 40.

Answer:

Sample size should be less than 85

Step-by-step explanation:

Sample size should be less than 85

Step-by-step explanation:

To use the infinite standard deviation formula, n has to be <= (0.05)(1700)

n <= 85

So the sample size has to be less than 85

In another way too,

n = sample size

N = population size

For population, we multiply correction factor to the infinite standard deviation

F is <= 0.05

[tex]n/{N} <0.05[/tex]

n<0.05x1700

n<85

Sample size should be less than 85

Answer:

The correct answer is -3

Step-by-step explanation:

attached is a number line to show diagrammatically how to count five units from the chosen point to point 2 on a number line.

Moving five units from -3 to 2 on a number line is given as follows:

-3 ⇒ -2 ⇒ -1 ⇒ 0 ⇒ 1 ⇒ 2

From the motion expression shown above, moving from -3 to 2 involves moving 5 units.

another way of determining the correct answer is to find the difference in interval between the two points as shown below:

Let the point be x

2 - x = 5 units

2 - 5 = x

∴ x = -3

Answer:

0.940

Step-by-step explanation:

Given the data:

Age in years(X) _____Height(Y)

7 _________ 47.3

8 _________48.8

5 __________41.3

8 _________ 50.4

8 ___________51

7 __________47.1

7 __________46.9

7 ___________48

9 __________51.2

8 __________51.2

5 __________40.3

8 __________48.9

6 __________45.2

5 __________41.9

8 __________49.6

The proportion of Variation explained by the line of best fit in a regression model can be determined by calculating the Coefficient of determination (R²) of the model.

Using the online R² calculator, the variation in the sample values of height which is estimated by the model is 0.9696² = 0.94012416.

Hence about 0.94 or 94% variation in sample values of height is estimated by the model while (1 - 0.94 = 0.06 or 6%) is explained by other factors.

Answer:

25

Step-by-step explanation:

By the vertical angle theorem, we can find that:

m∠1 = 85

By the corresponding angle theorem, we can find that:

m∠2 = 2x

By the alternate interior angle theorem, we can find that:

m∠3 = x - 10

We also know that angles 1, 2, and 3 are the measures of the angles of a triangle. So:

85 + 2x + (x - 10) = 180

Lets solve for x. Combine like terms.

75 + 3x = 180

Subtract 75 from both sides.

3x = 105

Divide both sides by 3.

x = 35

So now we know that x + 35. Knowing this, we can find the measure of angle 3 by plugging 35 for x in x - 10

m∠3 = 35 - 10 = 25

So the measure of angle 3 is 25.

I hope this helps. Happy studying.
