Use a number line to show the sum of 6+(-7) ?

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:

Step-by-step explanation:

3y – 6x = 3     -----------------------------------(I)

y = 2x + 1      ----------------------------------(II)

Substitute y = 2x + 1 in equation (I)

3*(2x+ 1) - 6x = 3

3*2x + 3*1 -6x = 3

  6x + 3 - 6x = 3              

               3 = 3

So, no solutions

Answer:

Use the substitution method to determine the solution type of the following system.

3y – 6x = 3

y = 2x + 1

Correct Answer

Infinitely many solutions

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:

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:

730000000 lbs?

Step-by-step explanation:

Answer:

730000000

Step-by-step explanation:

7.3 x 10^8

Do exponents first. 10^ 8 is the same as 10 x 10 x 10 x 10 x 10 x 10 x 10 x 10, which equals 100000000 x 7.3 = 730000000

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:

[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:

V=56

Step-by-step explanation:

7x8=56

56/7=8

Answer:

v=56

Step-by-step explanation:

1 Multiply both sides by 77.

v=8\times 7v=8×7

2 Simplify  8\times 78×7  to  5656.

v=56

First, determine what is 40% of $600. Multiple 40 (as a decimal) by 600.

0.4 x 600 = 240

Therefore, the discount is $240 off $600.

Subtract the two values to find price (before tax): 600 - 240 = 360

So the TV will cost $360 before tax.

The tax is 8.5%. Multiply 8.5 as a decimal by 360 to find the amount of tax added.

0.085 x 360 = 30.6

Add 30.6 and the price before tax to find the final price.

30.6 + 360 = 390.60

Therefore, the final price of the TV is $390.60

Answer:

A = a^2.....the Area (A) of a square = a^2...where a = one side

79 = a^2...now take the sqrt of both sides, this eliminates the ^2

sqrt 79 = a

8.888 rounded = 8.89 = a......so one side = 8.89 ft

Answer:

whats the question?

Step-by-step explanation:

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:

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:

16 years

Step-by-step explanation:

Let x represent the number of years. The suburb population is growing at a rate of 5000 per year after x years, it can be represented by the equation:

320000 + 5000x

The city population is declining at a rate of 14000 per year after x years, it can be represented by the equation:

624000 - 14000x

The number of years for the city and suburb population to be equal can be gotten from:

320000 + 5000x = 624000 - 14000x

14000x + 5000x = 624000 - 320000

19000x = 304000

x = 304000 / 19000

x = 16

In 16 years the populations of the suburb and the city be equal

Answer and Step-by-step explanation:

Solution:

(a) 8 + 3

Convert into BCD:

8 = 1000

3 = 0011

Add them:

8 + 3 = 11

Answer:

Step-by-step explanation:

pretty easy clap

bisecting is midpoint which makes the two angles congruent

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.

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.
