Answer:

4/13

Step-by-step explanation:

Count all cards that are 4, 5, 6, and 7 (each of 4 different suits) so the number of cards that is greater than 3 and less than 8 = 4(4) = 16.

There are 52 cards in a standard deck of cards.

P(greater than 3 and less than 8)

= 16/52

= 4/13

Answer:

x= -3/4 + y/4

Answer:

[tex]x = - \frac{3}{4} + \frac{1}{4} y[/tex]

Step-by-step explanation:

[tex] - 4x + y = 3[/tex]

[tex] - 4x = 3 - y[/tex]

[tex]x = - \frac{3}{4} + \frac{1}{4} y[/tex]

[tex]x = - \frac{3}{4} + \frac{1}{4} y[/tex]

Answer:

-7 + 5 = -2

Step-by-step explanation:

Basically, this equation can be thought of as 5 - 7, which would equal -2.

48 points gained in those 3 days.

Subtract 220 with 48, then add 96. Last step would be subtracting 220 with the amount they have now in those 3 days to find how much points the stock market gained in those 3 days.

Subtract 220-48.It‘ll be 172.

Add 172 with 96. 172+96=268.

Subtract 268 with how much points the stock market had 3 days ago. 268-220 would be 48.

The amount of change over those three days is 268 points.

Here,

The stock market dropped 220 points on Monday.

It lost another 48 points on Tuesday, and on Wednesday, it gained 96 points.

We have to find,  the amount of change over those three days.

What is amount?

The sum total of two or more quantities or sums, is called amount.

Now,

The stock market dropped 220 points on Monday.

It lost another 48 points on Tuesday.

Hence, the points after loss = 220 - 48 = 172

And, when it gained 96 points.

Then, the points after gain = 172 + 96 = 268

Hence, The amount of change over those three days is 268 points.

This question is incomplete, the complete question is;

Vic bought a new plasma TV for ​$2400. He made a down payment of ​$200 and then financed the balance through the store.​ Unfortunately, he was unable to make the first monthly payment and now pays 6​% interest per month on the balance​ (while he watches his​ TV).

What is Vic's Monthly interest payment ( Assume interest rates are 1/12 of annual interest rates)

Answer: Vic's Monthly interest payment is $132

Step-by-step explanation:

Given that;

Purchase cost of plasma Tv = $2400

down payment made = $200

so,

Balance financing from store = $2400 - $200 = $2,200

also given that Interest rate is 6% per month6

Now Monthly interest payment will be;

⇒ financing amount × interest rate

⇒ 2200 × (6/100) = 132

Therefore, Vic's Monthly interest payment is $132

The answer is 1

Answer:

x = 24.52

Step-by-step explanation:

Since this is a right triangle, use Pythagorean Theorem to solve for the hypotenuse.

Pythagorean Theorem: a² + b² = c²

24² + 5² = x²

576 + 25 = x²

601 = x²

√601 = x

Step-by-step explanation:

The break-even point is on both curves. The y-intercept can be used for the other point in each case.

The break-even point is where cost and revenue are the same:

 20/3x +50 = 10x

 50 = 10/3x . . . . . . . . subtract 20/3x

 15 = x . . . . . multiply by 3/10

 r = c = 10(15) = 150 . . . . for x = 10

Two points you can use for graphing the lines are ...

 cost: (0, 50) and (15, 150)

 revenue: (0, 0) and (15, 150)

9514 1404 393

Answer:

  6

Step-by-step explanation:

Cost and revenue are equal when ...

  C = R

  2.5x +21 = 6x

  21 = 3.5x . . . . . . subtract 2.5x

  6 = x . . . . . . . . . .divide by 3.5

The company must sell 6 items to break even.

Answer:

0.15 = 15% probability that it came from Site 3

Step-by-step explanation:

Conditional Probability

We use the conditional probability formula to solve this question. It is

[tex]P(B|A) = \frac{P(A \cap B)}{P(A)}[/tex]

In which

P(B|A) is the probability of event B happening, given that A happened.

[tex]P(A \cap B)[/tex] is the probability of both A and B happening.

P(A) is the probability of A happening.

In this question:

Event A: Being recalled

Event B: Recalled from site 3.

Probability of being recalled:

5% of 60%(from site 1)

7% of 30%(from site 2)

9% of 10%(from site 3).

So

[tex]P(A) = 0.05*0.6 + 0.07*0.3 + 0.09*0.1 = 0.06[/tex]

Probability of being recalled, being from site 3.

9% of 10%.

[tex]P(A \cap B) = 0.09*0.1 = 0.009[/tex]

If a randomly selected cell phone has been recalled, what is the probability that it came from Site 3?

[tex]P(B|A) = \frac{P(A \cap B)}{P(A)} = \frac{0.009}{0.06} = 0.15[/tex]

0.15 = 15% probability that it came from Site 3

Answer:

Step-by-step explanation:

you do multiplication first, then do the addition

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: It would be Todd for (P) and Jenna for (VP)

Step-by-step explanation: OK, so look there are four people wanting to run for president and vice presdent  so Todd and Jenna are running for a school club Todd has a higher chance of getting one of the two positions because if people vote enough for Todd to get the president position and has a change of getting vice president so If Jenna get lots of vote for (P) then she will run for (P) but if not flip flop Todd and Jenna positions and   one of them go to get some position or if not the candidates move up a step.
