Data collected in a mall recorded the shoe color worn by 30 customers. Based on this information, if there are 360 customers in the mall, how many customers would you expect to have a black shoe?

Answer:

k = [tex]5\frac{1}{3} ,7\frac{1}{3}[/tex]

Step-by-step explanation:

|19 - 3k| = 3

-3k = 3 - 19

-3k = -16

k = 16/3

k = 5 1/3

-19 + 3k = 3

3k = 3 + 19

3k = 22

k = 22/3

k = 7 1/3

2BD=CE

2(x+1)=x+10

2x+2=x+10

2x-x=10-2

x=8

Answer:A: reflection. B: congruent

Step-by-step explanation:(x, y) -> (-x, y) means that the triangle reflected from the (x, y) part of the graph to the (-x, y) part of the graph.

Answer: 9

Step-by-step explanation:

Answer:

Step-by-step explanation:

so the question is asking about the time from 1500 feet to 1100 feet.  How long did they fall, w/o a parachute.    aka   "freefall"   so,   at 1500 feet the jumper is really at time zero.   so, plug in to the formula

1100 = -16[tex]x^{2}[/tex] +1500  

( x represents seconds so i'll change it to t so we know it's time )  

1100 = -16[tex]t^{2}[/tex] + 1500

now we can solve for t  , to see how long the jumper falls

-400 = - 16[tex]t^{2}[/tex]      ( subtracting 1500 from both sides of equation )

25 = [tex]t^{2}[/tex]      ( dividing both sides by  -16 )

oh.. look at how nice that turns out.. :)

[tex]\sqrt{25}[/tex] = t  ( take the square root on both sides )

5 = t    

the jumper fell for 5 seconds to get to 1100 feet  

Answer:

14 and 16

Step-by-step explanation:

They are the ONLY  consecutive even numbers

And also

x and (x+2)

x(x+2)=224 ( product of a number and the consecutive of that number)

x ²+  2x-224=0

(x+16)(x-14) =0

x=-16 or 14

In this case 14 and (14+2)    14 and 16

The  integers are either 14 and 16 or -14 and -16.

x=7 and AC is 46

Answer:

y = -3

Step-by-step explanation:

2y + 6 = 0

2y = -6

y = -3

Since it's just y = -3, there is NO SLOPE and it's just one straight line going horizontally.

So just pick the graph where it's a horizontal line that only goes through the y-axises of -3 (i.e (0, -3), (1, -3), and etc)

Answer:

El pH del refresco es 3.42.

Step-by-step explanation:

Se puede calcular el pH del refresco usando la siguiente fórmula:

[tex]pH = -log([H^{+}])[/tex]

En donde:

[H⁺]: es la cocentración de los iones H⁺ de la solución

Entonces, el pH es:

[tex]pH = -log([H^{+}]) = -log(3.8\cdot 10^{-4}) = 3.42[/tex]

El resutlado obtenido nos permite concluir que ese refresco es ácido.

Por lo tanto, el pH del refresco es 3.42.

Espero que te sea de utilidad!

Usando su fórmula, se encuentra que el valor de PH de ese refresco​ es dado por 3.42.

Es dada por:

[tex]pH = -\log{H^{+}}[/tex]

Onde [tex]H^+[/tex] es la concentración.

En este problema, hay que la concentración es de [tex]H^+ = 3.8 \times 10^{-4}[/tex], por eso:

[tex]pH = -\log{H^{+}}[/tex]

[tex]pH = -\log{3.8 \times 10^{-4}}[/tex]

[tex]pH = 3.42[/tex]

El valor de PH de ese refresco​ es dado por 3.42.

Answer:

45.5

Step-by-step explanation:

First you would find 1/3 third of 10.50 and it is 3.5, you would then do 10.50 x 4 since it said 10.50 per half a yard, so you would do times 4 and you would get 42, you would then add 42 + 3.5 which equals 45.5.

Answer:

$24.50

Step-by-step explanation:

10.50 * 2 1/3 = 24.50

Answer:

Step-by-step explanation:

The antenna height is 41.23 feet if the support wire is attached to the top of the antenna.

Trigonometry is a branch of mathematics that deals with the relationship between sides and angles of a right-angle triangle.

We have:

A support wire is attached to the top of an antenna. The support wire connects to the ground 15 feet from the bottom of the antenna.

Let x be the height of the antenna.

We can find the length of the antenna using the trigonometric ratios:

As we know, the trigonometric ratio is defined as the ratio of the pair of a right-angled triangle.

Applying tan ratio in the right angle triangle:

tan70 = x/15

x =15tan70

x = 41.212 feet  ≈ 41.23 feet

Thus, the height of the antenna is 41.23 feet if the support wire is attached to the top of the antenna.

Answer:

3 runners will be in the last group

Step-by-step explanation:

So first you need to divide the 819 runners into 6 different groups. Once you do this... you get a total of 136. So there are 136 runners in each of the 6 groups. However, once you get to the end of the division problem, there is a remainder of 3. These three stand for the last 3 runners. Giving you your answer.

a. 4

Step-by-step explanation:

Copy and paste this:

I now that the area is: A = b×h/2, so: 16 = (x+4)(x)/2

-> x²+4x-32=0 -> x= -8 and x=4

x = -8 is impossible, so x=4

Answer: A. 4

Step-by-step explanation:

The equation for the area of a triangle is height times( base divided by 2)

4 + 4 = 8

8/2 is 4

4 times 4 is 16
