If you need 3 hot dogs for every 5 people and 1,200 people show up how many hot dogs would you need

Answer:

15/64 = 23.4 %

Step-by-step explanation:

Let's consider the first two selections. Let's call B the case in which she extracts a boy and G the case in whish she extracts a girl.

For each selection, the probabilty of event B (selecting a boy) is

[tex]P(B)=\frac{12}{32}=\frac{3}{8}[/tex]

While the probability of event G (selecting a girl) is

[tex]P(G)=\frac{20}{32}=\frac{5}{8}[/tex]

We are asked to find the probability that the first two events are B and then G:

[tex]P(B,G)[/tex]

In the first two selections, we have 4 possible combinations:

BB, BG, GB, GG

The probability for each combination is given by:

[tex]P(BB)=P(B)\cdot P(B) = \frac{3}{8}\cdot \frac{3}{8}=\frac{9}{64}=14.1 \%[/tex]

[tex]P(BG)=P(B)\cdot P(G) = \frac{3}{8}\cdot \frac{5}{8}=\frac{15}{64}=23.4 \%[/tex]

[tex]P(GB)=P(G)\cdot P(B) = \frac{5}{8}\cdot \frac{3}{8}=\frac{15}{64}=23.4 \%[/tex]

[tex]P(GG)=P(G)\cdot P(G) = \frac{5}{8}\cdot \frac{5}{8}=\frac{25}{64}=39.1 \%[/tex]

The second one is the probability we are searching for, so the probability that she will select a boy first and then a girl is 15/64, or 23.4%.

First thing to do is solve the given equation for v

-11v-7 = 4

-11v = 4+7

-11v = 11

v = 11/(-11)

v = -1

Once we know this, we can use it to compute the following

7v-10 = 7*(-1) - 10 = -7 - 10 = -17

Consider the given triangles.

Given: [tex]\angle C \cong \angle Q[/tex]

ASA congruence criterion states that if two angles and the included side of one triangle are congruent to the corresponding parts of another triangle, then the triangles are congruent.

AAS congruence criterion states that if two angles and a non-included side of one triangle are congruent to the corresponding parts of another triangle, then the triangles are congruent.

Consider the first part:

1. In triangles ABC and QPT

If we take [tex]\angle B \cong \angle P , BC \cong PQ[/tex] along with the given condition.

Then the triangles are congruent by ASA congruence criterion.

2. If we take [tex]\angle A \cong \angle T[/tex] and [tex]AC= TQ=3.2[/tex] along with the given condition.

Then the triangles are congruent by ASA congruence criterion.

3. As,[tex]\angle C \cong \angle Q[/tex], [tex]\angle A \cong \angle T[/tex] and [tex]\angle B \cong \angle P[/tex], so the triangles can not be congruent.

4. If we take [tex]\angle A \cong \angle T[/tex] and [tex]BC \cong PQ[/tex] along with the given condition.

Then the triangles are congruent by AAS congruence criterion.

5. If we take AC=TQ=3.2 and CB=QP=3.2 along with the given condition, then the triangles are congruent but by SAS congruence criteria neither by ASA nor AAS congruence criterion.

Answer: (a) 5

Step-by-step explanation:

[tex]\lim_{x \to 2} 5[/tex] means what is the y-value when x = 2 .

The given equation is: y = 5 so the y-value is 5 for all values of x

Answer: (c) 13

Step-by-step explanation:

f(x) = x² + 5x

f'(x) = 2x + 5

f'(4) = 2(4) + 5

      = 8 + 5

      = 13

Answer: (c) 2

Step-by-step explanation:

The question is asking what the y-value is when x = -2.  The graph shows that the coordinate (-2, 2) is on the curve. So, when x = -2, y = 2.

Answer:

lim x→2   5     =5

The slope is 13

lim x→-2   x^2 -2  =2

Step-by-step explanation:

lim x→2   5     =5

The limit of a constant is the constant

f(x) = x^2 +5x

We need to take the derivative

f'(x) = 2x+5

Then evaluate the derivative at x=4  (4,36)

f'(4) = 2*4 +5

     = 8+5

    = 13

The slope is 13

lim x→-2   x^2 -2  =2

Looking at the graph, the value of the function at -2  is about 2

We can also calculate it   (-2)^2 -2 =  4-2 = 2

Answer:

The answer is 180 feet.

Step-by-step explanation:

Here's your equation. (330 x W = 59,400).  If you want to find the width then divide 59,400 by 330 and you get 180 feet.

You can check by multiplying 330 and 180 which will result in 59,000.

So the correct answer is 180 feet.

Answer:

The distance to the earth's horizon from point P is 216.2198187 mi, appriximately 216.22 mi

Step-by-step explanation:

This is a right triangle:

Hypotenuse: c=3959 mi + 5.9 mi → c=3964.9 mi

Leg 1: a=x=?

Leg 2: b=3959 mi

Using the Pytagorean theorem:

a^2+b^2=c^2

Replacing the known values:

(x)^2+(3959 mi)^2=(3964.9 mi)^2

Solving for x: Squaring:

x^2+15,673,681 mi^2=15,720,432.01 mi^2

Subtracting 15,673,681 mi^2 both sides of the equation:

x^2+15,673,681 mi^2-15,673,681 mi^2=15,720,432.01 mi^2-15,673,681 mi^2

x^2=46,751.01 mi^2

Square root both sides of the equation:

sqrt(x^2)=sqrt(46,751.01 mi^2)

x=216.2198187 mi

x=216.22 mi

The distance from the point P to the Earth’s horizon distance is approximately 216.22 mi.

To find the distance from the point P to the earth's horizon, we can use the concept of the earth's curvature.

The distance from the center of the earth to point P is the radius of the earth plus the distance from the center to the surface, which is 3959 + 3964.9 = 7923.9 miles.

The distance to the horizon can be found using the formula for the horizon distance, which is approximately equal to the square root of two times the product of the earth's radius and the total distance from P to the surface of the earth.

So, x = sqrt(2 * 3959 * 7923.9) = 216.22 mi.

Answer:

Red grapefruit costs more per pound.

Step-by-step explanation:

Red grapefruit

y =2x

This is in the form y= mx+b  where m is the slope and b is the y intercept

The cost per pound is the slope, which is 2

The cost per pound is $2

Pink grapefruit

We need to find the slope

We have 2 points (0,0) and  (4,4)

m = (y2-y1)/(x2-x1)

   = (4-0)/(4-0)

   =4/4

  = 1

The slope is 1

The cost per pound is $1

Answer:

The red grapefruit.

Step-by-step explanation:

Let's think for a moment about what the equation [tex]y=2x[/tex] represents. For any value of x, our y is going to be double that. What do our y and our x represent, then? We're told that y represents the cost of the red grapefruit, and that x is the weight of that grapefruit in pounds. What our equation then tells us is that the cost (in dollars) of red grapefruit is always twice as much as its weight.

What about the pink grapefruit? Instead of an equation, we're given a line on a coordinate grid. Let's see if we can find a pattern here. The y axis is still cost, and the x axis is still weight. We see at the very beginning that when x = 0, y = 0 too. Finding a few more points, we can see that when x = 1, y = 1; when x = 2, y = 2; and when x = 3, y = 3. This pattern continues, and we can capture it with the equation [tex]y=x[/tex].

Comparing the two equations [tex]y=2x[/tex] (red grapefruit) and [tex]y=x[/tex](pink grapefruit) we can see that the cost of red grapefruit grows twice as fast as pink grapefruit. To see which one costs more per pound, we can simply set x = 1 to find that red grapefruit costs [tex]y=2(1)=\$2[/tex] per pound, while pink grapefruit costs [tex]y=\$1[/tex] per pound, and since [tex]\$2>\$1[/tex], the red grapefruit costs more.

Answer:

(x, y ) = (3, 14 )

Step-by-step explanation:

since both equations express y in terms of x, equate the right sides

7x - 7 = 6x - 4 ( subtract 6x from both sides )

x - 7 = - 4 ( add 7 to both sides )

x = 3

substitute x = 3 into either of the 2 equations for y

using y = 6x - 4 = (6 × 3 ) - 4 = 18 - 4 = 14

solution is (3, 14 )

Answer:

Hello from MrBillDoesMath!

Answer:

p = 12

Discussion:

Assume we have a right trainload (looks like it but no angle indication given).  By the Pythagorean Theorem

p^2 + 5^2 = (p+1) ^ 2          =>

p^2 + 25 = p^2 + 2p + 1     =>

25 = 2p + 1                          =>         (subtract p^2 from both sides)

25 -1 = 2p                            =>         (subtract 1 from both sides)

24 = 2p =>

p = 24/2 = 12                       =>         (divide both sides by 2)

Answer:

x- 5

y- 6

Step-by-step explanation:

A proportional relationship is a relationship for which a proportional constant y/x exists and for which it passes through (0,0) or the origin.

The proportional constant is 6.

18/3=6

42/7=7

54/9=6

Thus the filled in blanks should be x 1, 3, 5, 7, 9 and y 6, 18, 30, 42, 54.

Answer:

Step-by-step explanation:

From the given table, if we divide each pair as y/x, we find the ratio is 6.

[tex]\frac{18}{3}=6\\\frac{42}{7}=6\\\frac{54}{9}=6[/tex]

Therefore, the missing numbers have to be in the same ratio.

[tex]\frac{x}{1}=6\\x=6[/tex]

[tex]\frac{30}{x}=6\\ x=5[/tex]

So, the missing numbers are 5 and 6, because they are also in the same ratio of 6.

Water = 1/5 of the volume of the syrup

Step-by-.step explanation:

Suppose we had  1000 cm^3 of syrup  and the new volume after adding water is x cm^3.  Now the amount of sugar stays the same so we have the equation 35 * 1000 =  25 * x

x = (30 * 1000) / 25 =  30,000 / 25

= 1200 cm^3

So we need to add 200 cm^2 of water .

In general terms,  we need to add water which equals 1/5 of the volume of the syrup,

It is 2.5 not what the other dude said it was

Answer:

The correct option is 2.

Step-by-step explanation:

The given function is

[tex]f(x)=ax+b[/tex]

Where, a and b are positive numbers.

The given function is the slope intercept form of a linear function. Where a is the slope and b is y-intercept.

Since slope is positive therefore function approaches to infinity as x approaches to infinity and function approaches to negative infinity as x approaches to negative infinity.

It is also proved by using limits.

[tex]lim_{x\rightarrow \infty}f(x)=lim_{x\rightarrow \infty}(ax+b)[/tex]

Apply limits.

[tex]lim_{x\rightarrow \infty}f(x)=a(\infty)+b=\infty[/tex]

Similarly,

[tex]lim_{x\rightarrow -\infty}f(x)=lim_{x\rightarrow -\infty}(ax+b)[/tex]

Apply limits.

[tex]lim_{x\rightarrow -\infty}f(x)=a(-\infty)+b=-\infty[/tex]

Therefore option 2 is correct.

[tex]f(x)\rightarrow \infty \text{ as }x\rightarrow \infty[/tex]

[tex]f(x)\rightarrow -\infty \text{ as }x\rightarrow -\infty[/tex]

Answer:

k=3

Step-by-step explanation:

Given equation is

[tex]x^2+y^2 -6y-12=0[/tex]

First we move -12 to the other side by adding 12 on both sides

[tex]x^2+y^2 -6y =12[/tex]

We apply completing the square method to get square form (y-k)^2

Lets take coefficient of y and then divide it by 2

-6 divide by 2  is -3

Then we square it (-3)^2 = 9

We add 9 on both sides

[tex]x^2+y^2 -6y + 9=12+9[/tex]

[tex]x^2+(y^2 -6y + 9)=21[/tex]

Now we factor,  y^2 - 6y +9 is (y-3)(y-3)= (y-3)^2

[tex]x^2+(y-3)^3=21[/tex]

Now we compare with x^2 + (y-k)^2 = 21 and find the value of k

The value of k = 3
