Brown Delivery Company delivers its standard crates using a fleet of vans and trucks. A van can hold up to 20 standard crates, and a truck can hold up to 35 standard crates. If Brown Delivery Company needs to deliver exactly 270 standard crates at one time using 12 vehicles, which system of linear equations could be used to determine the number of vans, x, and the number of trucks, y, needed for this delivery?

Answer:

  62°

Step-by-step explanation:

If x is the largest angle, the sum of angles in the triangle is ...

  x + (x -3) +(x -3) = 180

  3x -6 = 180 . . . . . simplify

  x -2 = 60 . . . . . . . divide by 3

  x = 62 . . . . . . . . . .add 2

The largest angle is 62°.

Answer:

Bethany did not do better than Richie because her average score was less than his.

Step-by-step explanation:

Average Value

The average or mean value of m successes out of n tries is given by:

[tex]\displaystyle \bar x=\frac{m}{n}[/tex]

During a practice session playing basketball, Richie made m=12 free throws from n=15 attempts. His average score was:

[tex]\displaystyle \bar x=\frac{12}{15}=0.8[/tex]

Bethany made 8 free throws for every 3 that she missed, this means she made 8 out of 11 attempts. Her average score was:

[tex]\displaystyle \bar x=\frac{8}{11}=0.72[/tex]

Bethany did not do better than Richie because her average score was less than his.

The person that did better is Richie. This is because the percentage of free throws made by Richie is higher than that of Bethany.

In order to determine who did better, the percentage of free throws made has to be determined.

The percentage of free throws made by Richie =( 12 / 15) x 100 = 80%

The  percentage of free throws made by Bethany = [(8-3) / 8] x 100 = 62.50%

Answer:

[tex]P(L\ or\ C) = 0.13[/tex]

Step-by-step explanation:

Given

Represent loose threads with L, Crooked stitching with C.

So, we have:

[tex]P(L) = 6.5\%[/tex]

[tex]P(C) = 9.5\%[/tex]

[tex]P(L\ and\ C) = 3\%[/tex]

Required

Calculate P(L or C)

In probability:

[tex]P(A\ or\ B) = P(A) + P(B) - P(A\ and\ B)[/tex]

In this case:

[tex]P(L\ or\ C) = P(L) + P(C) - P(L\ and\ C)[/tex]

Substitute values for P(L), P(C) and P(L and C)

[tex]P(L\ or\ C) = 6.5\% + 9.5\% - 3\%[/tex]

[tex]P(L\ or\ C) = 13\%[/tex]

Convert to decimal

[tex]P(L\ or\ C) = 0.13[/tex]

Hence:

The required probability is 0.13

Answer:

Price of the meals

Scatter plot with a trendline

Step-by-step explanation:

None of the provided options are correct. The independent variable was Price of the meals, and they should present the data as a Scatter plot with a trendline. The Price of the meal is the independent variable because it does not depend on any other variable and is instead the cause of the burping frequency which would be the dependent variable in this scenario. The Scatter plot would allow you to mark each individual's burping frequency on the same prices for the meal, since you would most likely have more than one value of burping frequency for the same priced meal.

Answer:

The correct option is C : x² + (y +3)² = 9 .

Step-by-step explanation:

We know that the general equation for a circle is ( x - h )² + ( y -k )²= r², Where,

Let the point be ( 0 , -y) , since it is on negative y axis . And the circle passes through the origin that is (0,0) . Hence the center will be 3 units down the y - axis that is ( 0 , -3) .Hence h will be 0 and y = (-3) .

Now its given that the radius of the circle is 3. So on substituting r = 3 , in standard form we have ,

⇒ ( x -h )² + ( y - k )²= r²

⇒ ( x - 0)² + { y - (-3) }² = 3²

⇒ x² + ( y + 3) ² = 3²

⇒ x² + ( y + 3)² = 9

Answer:

$25,226

Step-by-step explanation:

We know that one billion is equal to 1,000 millions

So, we first multiply 80.8 by 1,000 so we can use millions as our unit.

Which gives you $80,800

So, East Dakota spent $80,800 million in 2016 for the 3.203 million people. Right now, we just ignore the "million" part and divide 80,800 by 3.203 which is around 25,226.35029659694

Now we just round it to the nearest dollar and since the tens place is only at 3, we round down.

Hence, our answer is $25,226

Answer

0.00336

Step-by-step explanation:

Given :

P(Brown), P(Br) = 0.4

P(Blue) = P(b= 0.35

P(green,) = P(g) = 0.12

P(gray), P(Gr) = 0.07

If 3 individuals are selected, the probability that one has brown eye, 1 has Grey and one has green.

Since the probabilities are independent :

P(Br) * P(Gr) * P( g)

0.3 * 0.07 * 0.12

= 0.00336

Assuming you're equipped with the error function,

[tex]\mathrm{erf}(x)=\displaystyle\frac2{\sqrt\pi}\int_0^x e^{-u^2}\,\mathrm du[/tex]

whose derivative is

[tex]\dfrac{\mathrm d}{\mathrm dx}\mathrm{erf}(x)=\dfrac2{\sqrt\pi}e^{-x^2}[/tex]

by substituting x = √y, so that x ² = y and 2x dx = dy, we have

[tex]\displastyle\int\sqrt y e^{-y^3}\,\mathrm dy=\int 2x^2 e^{-x^6}\,\mathrm dx[/tex]

Then if u = x ³ and du = 3x ² dx, we have

[tex]\displaystyle\int\sqrt y e^{-y^3}\,\mathrm dy=\int\frac23 e^{-u^2}\,\mathrm du[/tex]

[tex]\displaystyle\int\sqrt y e^{-y^3}\,\mathrm dy=\frac{\sqrt\pi}3\mathrm{erf}(u)+C[/tex]

[tex]\displaystyle\int\sqrt y e^{-y^3}\,\mathrm dy=\frac{\sqrt\pi}3\mathrm{erf}(x^3)+C[/tex]

[tex]\displaystyle\int\sqrt y e^{-y^3}\,\mathrm dy=\boxed{\frac{\sqrt\pi}3\mathrm{erf}\left(y^{\frac32}\right)+C}[/tex]

If you're not familiar with the error function, unfortunately there is no elementary antiderivative...

Answer:

x=6

Step-by-step explanation:

This equation requires simplifying. We start with moving like terms to each other:

3 + 9 = 4/3x + 2/3x

After this, add the like terms together:

12 = 6/3x

6/3 will simplify into 2:

12=2x

Finally, divide both sides by 2:

6=x

Answer:

The x-coordinate is negative, and the y-coordinate is negative.

Answer and Step-by-step explanation: Two triangles are congruent when they have the same 3 sides and the same 3 angles.

One way to find if they are congruents is a theorem called "Side-Angle-Side" (SAS): if two sides and its included angle is equal to the other triangle's corresponding sides and angles, the triangles are congruent.

In the graph below, in triangle DEK, as Steve determined, side DK measures 12. In triangle ABC, side BC is also 12. The angles K and C are equals, so if sides EK and AC are congruent, SAS Congruent Theorem is correct.

To test it, find distances EK and AC, which is calculated as:

[tex]d=\sqrt{(x_{1}-x_{2})^{2}-(y_{1}-y_{2})^{2}}[/tex]

EK is a distance between points E(-6,4) and K(0,-4)

[tex]d=\sqrt{(-6-0)^{2}-(4+4)^{2}}[/tex] = 10

AC is a distance between points A(3,6) and C(9,-2)

[tex]d=\sqrt{(3-9)^{2}-(6+2)^{2}}[/tex] = 10

EK and AC have the same distances between each point, i.e., segment EK measures the same as segment AC, 10 units.

Therefore, triangles DEK and BAC are congruent proven by SAS Congruence Theorem.
