Half of a number plus three
times the number.

Write it in expression or equation solve the equation

Answer:

A. 19

Step-by-step explanation:

The median is the middle-point

The middle-point is also the number that is halfway into the set. To find the middle-point, the data should be arranged in order from least to greatest. If there is an even number of items in the data set, then the middle-point is found by taking the mean (average) of the two middlemost numbers.

Answer:

£25 or £20.10

Step-by-step explanation:

calculate the area to be painted:

2.1x4.5= 9.45m^2 for each wall

x4= 37.8m^2

area of door= 1.8x0.9= 1.62m^2

subtract the area of the door from the wall area

37.8-1.62= 36.18m^2 to be painted

divide the area by the area that 1L of paint can cover

16.18/12= 3.015 L needed

if 1.5L= £10 then, 3L= £20. she needs 2 cans + an extra 0.015 L- so another can (3 cans total) add price up.

£30- but buy 2 get 3rd 1/2 price, so take £5 off. price is £25

or

calculate price for 0.015L

1.5=£10

divide both sides by 100

0.015= £ 0.10

if 1.5L= £10 then, 3L= £20. she needs 2 cans + an extra 0.015 L

£20+£0.10= £20.10

First divide both sides of the inequality by 3.

On the left, the 3's cancel and you're left with j

and on the right, 6 divided by 3 is 2.

So we have j >2 which is the solution to this inequality.

I have graphed the inequality for you below.

Start with an open dot on 2.

We use an open dot because j > 2 but it is not equal to 2.

Then draw an arrow to the left to

Answer:

Yes, because it passes the vertical line test

Step-by-step explanation:

A function has one output for each input.  This is called a one to one correspondent.  This is shown by the vertical line test

This graph passes the vertical line test and is therefore a function

Answer:

D

Step-by-step explanation:

The vertical line test is a visual way to determine if a curve is a graph of a function or not. A function can only have one output, y, for each unique input, x.

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

Example: The first table is a function because each input value has only 1 output value, but the second table has more that one output value per input.  (View Attached Picture Below)

The input value 4 in Table A has only 1 output value, 20. But in Table B, the input value for 4 has 2 output values, 16 and 17. So Table A is a function, while Table B is not.

Answer:

50%

Step-by-step explanation:

We have that the mean is 52000 miles (m) and the standard deviation is 2000 miles (sd), so we are asked:

P (x <52000)

P ((x - m) / sd <(52000 -52000) /2)

P (z <0)

If we look in the normal distribution table we have to:

P (x <52000) = 0.5

That is, the probability is of randomly selecting a car with a mileage less than 52,000 miles 50%

Answer:2*sqrt(130)

Step-by-step explanation:[tex]From right triangle $AXC$, we have $\angle XAC = 90^\circ - \angle XCA$. We also must have $\angle YCB + \angle ACB + \angle XCA = 180^\circ$, so $\angle YCB = 180^\circ - 90^\circ - \angle XCA = 90^\circ - \angle XCA$, which means $\angle YCB = \angle XAC$. Combining this with $\angle X = \angle Y$, we have $\triangle XCA \sim \triangle YBC$ by AA Similarity, and\[\frac{CX}{AX} = \frac{BY}{CY},\]so\[\frac{CX}{4} = \frac{18}{2CX}.\]\\\\This gives us $2CX^2 = 72$, so $CX^2 =36$ and $CX=6$. \\\\\\\\[/tex][tex]Therefore, $CY = 12$.Applying the Pythagorean Theorem to right triangles $XCA$ and $CYB$ gives us\begin{align*}CA^2 &= XA^2 + XC^2 = 16 + 36 = 52,\\BC^2 &= CY^2 + BY^2 = 144 + 324 = 468.\end{align*}Applying the Pythagorean Theorem to right triangle $ABC$ gives\[AB = \sqrt{AC^2 + BC^2} = \sqrt{52 + 468} = \sqrt{520} = \boxed{2\sqrt{130}}.\](We can also compute $AB$ by dropping a perpendicular from $A$ to $\overline{YZ}$, which creates a right triangle.)[/tex]

The length of the side AB from the figure is approximately 22.8.

Given a rectangle WXYZ.

Consider triangles ΔACX and ΔBCY.

∠AXC = ∠BYC

Also, ∠CAX + ∠ACX = 180° - 90°

So, ∠CAX = 90° - ∠ACX [Equation 1]

Given that ∠ACB = 90°

Also, ∠ACX, ∠ACB, and ∠BCY form linear angles.

So, ∠ACX + ∠ACB + ∠BCY = 180°

So, ∠ACX + 90° + ∠BCY = 180°

∠ACX + ∠BCY = 90°

∠BCY = 90° - ∠ACX [Equation 2]

From [Equation 1] and [Equation 2], ∠CAX = ∠BCY

By AA similarity, triangles ΔACX and ΔBCY are similar.

So, the corresponding sides are proportional.

AX / CY = CX / BY

4 / 2CX = CX / 18

(CX)² = 36

CX = 6

Now, using the Pythagoras theorem:

AC = √(4² + 6²) = √52

BC = √(18² + 12²) = √468

So, AB = √(√52)² + (√468)²

            = √520

            ≈ 22.8

Multiplication is the process of multiplying, therefore, adding a number to itself for the number of times stated. The product of the two resulting integers is 80.

Multiplication is the process of multiplying, therefore, adding a number to itself for the number of times stated. For example, 3 × 4 means 3 is added to itself 4 times, and vice versa for the other number.

Let the unknown integer be represented by x. Given that the sum of two consecutive integers is -15. Therefore, we can write,

x + (x+1) = -15

2x + 1 = -15

2x = -16

x = -8

Thus, the smaller integer is -9 and the larger integer is -8.

Now, If 1 is added to the smaller integer and 2 is subtracted from the larger integer.

Smaller Interger = -9 + 1 = -8

Larger Integer = -8 - 2 = -10

Further,  the product of the two resulting integers is,

Product = -8 × -10

             = 80

Hence, the product of the two resulting integers is 80.

The graph is a vertical shift of the parent function 2 units up.

Step-by-step explanation:

Our the function is:

y = √x + 2

Its parent function is: f(x) = √x

Answer:

The graph is a vertical shift of the parent function 2 units up.

Step-by-step explanation:

Our the function is:

y = √x + 2

Its parent function is: f(x) = √x

Then, the transformation can be rewritten as: f(x) + 2, which has the form f(x) + c, which is a vertical shift of f(x) c units up. Therefore, in this case, the parent function is shifted 2 units up.

This question is based on the concept of graph .Hence,the correct option is (c) i.e. the graph is a vertical shift of the parent function 2 units up.

Given:

The function of graph is [tex]\bold{y=\sqrt{x+2}}[/tex].

Its parent square root function is [tex]\bold{f(x)= \sqrt{x}}[/tex].

By the parent function we have to obtain given function ,So,we have to add on both  sides 2,

f(x)+2 = [tex]\sqrt{x+2}[/tex]

Thus, we have to added 2 to transform the parent root function into given function.Therefore, graph is shifted vertically 2 units up.

Hence,the correct option is (c) i.e. the graph is a vertical shift of the parent function 2 units up.

Answer:

x = 45 degree as it is an alternate angle we use 135 degree to prove supplementary angles across the straight line add up to 180 degree.

Therefore we prove 180-135 = 45 degree and say all angles on straight line add up to 180 degree, and recognize x is an alternate angle as the arrow straight lines are parallel and create precise alternate lines from which we can prove multiple supplementary and alternate angles.

Supplementary can be either angle will always be supplementary from either 45 degree angle matched with any 135 degree as they don't have to be together to be supplementary they only have to equal 180 degree to be a supplementary angle.

Answer:

x, y, 4, 0

Step-by-step explanation:

To determine the inverse of the given function change f(x) to y switch x and y and solve for  y.

f(x) = sqrt(x - 4)

y = sqrt(x - 4)

x = sqrt(y - 4)

x^2 = y - 4

x^2 + 4 = y

y = x^2 + 4

The domain of the inverse is the same as the range of the original function.

inverse f(x) = x^2 + 4

x^2 + 4 >= 4

x^2 >= 0

x >= 0

The resulting function can be written as inverse f(x) = x^4 + 4, where x >= 0.

Answer:

A) The probability that each player gets an ace, a 2 and a 3 with the order unimportant = (72/1925) = 0.0374

B) The probability of winning the jackpot = (1/1200) = 0.0008333

Step-by-step explanation:

A) There are four Aces, four 2's, and four 3's, forming a set of 12 cards

These cards are to be divided at random between 4 players.

What is the probability that each player gets an ace, a 2 and a 3.

We start with the first player, the probability of these cards for the first player, with order not important (because order isn't important, there are 6 different arrangement of the 3 cards)

6 × (4/12) × (4/11) × (4/10) = (16/55)

Then the second player getting that same order of cards

6 × (3/9) × (3/8) × (3/7) = (9/28)

Third player

6 × (2/6) × (2/5) × (2/4) = (2/5)

Fourth player

6 × (1/3) × (1/2) × (1/1) = 1

Probability that each of the players get different cards is then a multiple of the probabilities obtained above

= (16/55) × (9/28) × (2/5) × 1

= (288/7700) = (72/1925) = 0.0374

B) The concluding part of the B question.

To win the jackpot, the numbers on your ticket must match the three white balls and the SuperBall. (You don't need to match the white balls in order). If you buy a ticket, what is your probability of winning the jackpot?

Probability of wimning the jackpot is a product the probability of getting the 3 white balls correctly (order unimportant) and the probability of picking the right red superball

Probability of picking 3 white balls from 10

First slot, any of the 3 lucky numbers can fill this slot, (3/10)

Second slot, only 2 remaining lucky numbers can fill this slot, (2/9)

Third slot, only 1 remaining lucky number can fill this slot, (1/8)

(3/10) × (2/9) × (1/8) = (1/120)

Probability of picking the right red superball

(1/10)

Probability of winning the jackpot = (1/120) × (1/10) = (1/120) × (1/10) = (1/1200) = 0.0008333
