I need help with this what’s the answer

Answer:

$11

Step-by-step explanation:

[tex]\left\begin{array}{c|ccc}&$Lose \$25&$Gain \$5&$Gain \$45\\$Stock ABC&40\%&15\%&45\%\end{array}\right[/tex]

We want to calculate the expected gain or loss of Stock ABC with the probabilities above.

Note that loss is written in negative.

[tex]E$xpected Value =$ (-25 \times 40\%)+(5 \times 15\%) + (45 \times 45\%)\\=(-25 \times 0.4)+(5 \times 0.15)+(45 \times 0.45)\\=-10+0.75+20.25\\=\$11[/tex]

Stock ABC has an expected gain of $11.

Answer:

Step-by-step explanation:

[tex] 3{x}^{4} - 48[/tex]

Factor out 3 from the expression:

[tex]3( {x}^{4} - 16)[/tex]

Using [tex] {a}^{2} - {b}^{2} = (a - b)(a + b)[/tex],factor the expression

[tex]3(( {x}^{2} ) ^{2} - {(4)}^{2} )[/tex]

[tex]3( {x}^{2} - 4)( {x}^{2} + 4)[/tex]

Again, factor using the formula of [tex] {a}^{2} - {b}^{2} [/tex]

[tex]3(x - 2)(x + 2)( {x}^{2} + 4)[/tex]

[tex](25x + 8)(x + 2)[/tex]

Step-by-step explanation:

[tex]25x^{2} + 58x + 16 = 25x^{2} + 50x + 8x + 16 = 25x(x + 2) + 8(x + 2) = (25x + 8)(x + 2)[/tex]

Answer: Distance is 17

Step-by-step explanation:

[tex]d = √((x2-x1)2 + (y2-y1)2)[/tex]

[tex](x2-x1) = (2 -6) = 8[/tex]

[tex](y2-y1) = (17 - 2) = 15[/tex]

Add them all together

[tex](8)2 + (15)2 = 64 + 225 = 289[/tex]

Square 289

[tex]\sqrt{289} =17[/tex]

Answer:

4 and 5/6; 29/6.

Step-by-step explanation:

3/7 of x is 2-1/14.

(3/7)x = 29/14

x = (29/14) * (7/3)

x = (29/2) * (1/3)

x = 29/6

3/7 of 4 and 5/6 is 2 1/14.

Hope this helps!

Answer:

29/6

Answer:

t = 4

Step-by-step explanation:

you have -8 and twelve you equation is x -12 = -8 so we just have to flip the equation around to make it x = 12 -8 which is easy . You just have to make sure you don't get mixed up while flipping the signs.

The value of t is 4.

An equation is a combination of different variables, in which two mathematical expressions are equal to each other.

Given that,

The temperature in January = 12 °F

And the low temperature is = -8 °F

The equation of temperature t can be given as

t= high temperature + low temperature

t= 12 - 8

t=4

The value of t is 4.

Answer:

Gabriella's average original speed was 56  [tex]\frac{mi}{h}[/tex]

Step-by-step explanation:

Let's use the equation that defines the average speed "v" of Gabriella during the time (t) that her trip took:

[tex]v = \frac{distance}{time} \\v=\frac{400}{t}[/tex]

Next let's write a similar average speed equation for the case in which she drove at (v - 7 mi/h) during the same time "t" and covered 350 miles:

[tex](v-7)=\frac{350}{t}[/tex]

Notice that the time "t" in the denominator appears equally in both equations we wrote, so let's isolate them on the right:

[tex]\frac{v}{400} =\frac{1}{t} \\and\\\frac{(v-7)}{350} =\frac{1}{t}[/tex]

now equal both expression since they both share the same value on the right, and solve for the unknown "v":

[tex]\frac{v}{400} =\frac{(v-7)}{350} \\350\,v=400\,(v-7)=\\350\,v=400\,v-2800\\2800=50\,v\\v=\frac{2800}{50} \,\,\frac{mi}{h}\\v=56\,\,\frac{mi}{h}[/tex]

Answer:

0.64

Step-by-step explanation:

4 out of 5 free throws is 0.8 as a decimal.

The probability that Brian will make 2 free throws is 0.8 for the first one, and then 0.8 of that for the second one. That means you multiply the two to get your answer and 0.8 times 0.8 = 0.64.

AB

Step-by-step explanation:

A tangent is a line that touches a circle but never goes through it. Wherever the the tangent touches is called the point of tangency and creates a perpendicular bisector (90° angle).

A tangent to a circle is a straight line that touches the circle at only one point.

Answer:

2/56

Step-by-step explanation:

You'll be disappointed to find out these are *all* complex numbers, because the set of real numbers is a subset of the complexes.

Probably the question means to ask, "which of these numbers is strictly non-real?" in which case D would be the answer because it contains the square root of a negative number that introduces the imaginary unit i. All the other options are strictly real numbers.

Answer:

9 years

the tree doubles in height

we can make a model

1 x 2 = 2

2 x 2 = 4

4 x 2 = 8

8 x 2 = 16

16 x 2 = 32

32 x 2 = 64

64 x 2 = 128

128 x 2 = 256

256 x 2 = 512

512 x 2 = 1024

Let's say 1024 is the maximum height

half the maximum height is 1024 x 0.5 = 512 so it will take 9 years because it reached 512 on the 9th year

Answer:

224 points.

Step-by-Step Explanation:

We know that Andrew scores 16 points per basketball game.

He continues scoring the same amount of points for 14 more games.

Therefore, the total amount of points he will score in total will be 16 multiplied by 14.

Since 16 times 14 is 224, this means that Andrew will score 224 points in total.

Answer: 40 stamps

Step-by-step explanation:

Let Maddy = M and Simon = S

Given that maddy had twice as many stamps as simon. That is,

M = 2S ....(1)

After maddy sold 60 stamps, simon had twice as many stamps as maddy. That is,

S = 2( M - 60) .... (2)

Substitutes M for 2S from equation (1) into equation (2)

S = 2( 2S - 60 )

Open the bracket

S = 4S - 120

Collect the like terms

S - 4S = -120

- 3S = - 120

S = 120/3

S = 40

Substitute S into the equation (1)

M = 2 × 40 = 80

Maddy has 80 - 40 = 40 stamp

Therefore, Maddy has 40 more stamps than simon in the beginning.

Answer:

444

Step-by-step explanation:

13 + 34 + 25 + 10 + 8 = 90

10/90 * 4000 = 444

Answer: You will expect 444 white cars passed by.

Step-by-step explanation:

The are 5 different colors so we need to find the probability of white cars.

There are 10 white cars But we need to find the total number of cars in all.

13+34+25+10+8 = 90

so the probability of a white car passing by is 25/90 = which reduces to 10/90  

Now multiply 1/9 by 4000.

1/9 * 4000  =  444

Answer:

a) square numbers

b) 9

Step-by-step explanation:

A square number is a number that can be made by multiplying a whole number by itself(49 is a square number because 7*7=49, 64 is a square number because 8*8=64).  The square root of 36 is 6.  The square root of 25 is 5.  The square root of 16 is 4.  Thus, following the pattern, the square root of 9 is 3.

Answer:

41.36% decrease

Step-by-step explanation:

Since it told us that the total amount of people was 1,100 people, we know our percentage is going to have to be x/1100.

We calculate how many less people came to the pool after the weeks have passed, which totals up to 455 people (455 people decrease).

So,

455/1100 = 0.413636 or 41.36% decrease.
