The number of choices available to them were \(65318400\) , \(1080\) and \(311040\).

Combination is a mathematical technique that determines the number of possible arrangements in a collection of items where the order of the selection does not matter.

Combination \((^nC_{r} ) = \frac{n ! }{r!(n-r)!}\)

We have, to perform \(2\) short plays, \(4\) recitals and \(3\) dance programmes in any order.

So,

The number of ways to select   \(2\)  short plays out of \(3\)  using the mentioned formula,

\((^3C_{2} ) = \frac{3 ! }{2!(3-2)!}\)

         \(= \frac{3 *2*1 }{2*1*1}=3\)

Now,

The number of ways to select  \(4\)  recitals out of \(6\) using the mentioned formula,

\((^6C_{4} ) = \frac{6 ! }{4!(6-4)!}\)

        \(= \frac{6*5*4 ! }{4!*2*1} =15\)

Now,

The number of ways to select \(3\) dance programs out of \(4\) using the mentioned formula,

\((^4C_{3} ) = \frac{4 ! }{3!(4-3)!}\)

         \(= \frac{4*3 ! }{3!*1!}=4\)

Now,

The number of ways to arrange \(9\) program using the mentioned  formula,

\((^9P_{9} ) = \frac{9 ! }{(9-9)!}\)

        \(=9!\)

        \(=9*8*7*6*5*4*3*2*1=362880\)

So, the total number of ways by multiplying the values

i.e. \(362880*4*15*3=65318400\)

So, the total number of ways to perform the programs are \(65318400\) .

We have, to perform the programmes of the same kind.

So,

The number of ways to arrange \(3\) different program using the mentioned  formula,

\((^3P_{3} ) = \frac{3 ! }{(3-3)!}=3!=3*2*1=6\)

So, the total number of ways by multiplying the values,

i.e. \(6*4*15*3=1080\)

We have to perform, the programmes of the same kind and considering the order of performance of the programmes of the same kind.

So,

The number of ways to select  \(2\)  short plays out of \(3\)  using the mentioned formula,

i.e. \((^3P_{2} ) = \frac{3 ! }{(3-2)!}=\frac{3!}{1!} =3*2=6\)

Now,

The number of ways to select  \(4\)  recitals out of \(6\) using the mentioned formula,

\((^6CP_{4} ) = \frac{6 ! }{(6-4)!}=\frac{6!}{2!} =\frac{6*5*4*3*2!}{2!} =360\)

Now,

The number of ways to select \(3\) dance programs out of \(4\) using the mentioned formula,

\((^4P_{3} ) = \frac{4 ! }{(4-3)!}=\frac{4!}{1!}=4*3*2=24\)

So,

The number of ways to arrange \(3\) different program using the mentioned  formula,

\((^3P_{3} ) = \frac{3 ! }{(3-3)!}=3!=3*2*1=6\)

So, the total number of ways by multiplying the values,

i.e. \(6*24*360*6=311040\)

Hence, we can say that the number of choices available to them were \(65318400\) , \(1080\) and \(311040\).

The solution of the expression is x=0 and it is the only solution that is an integer.

An expression in mathematics is a combination of numbers, variables, and mathematical operations that evaluates to a numerical value or an algebraic expression.

To do this, we need to pick a range of x values and substitute them into each equation to find the corresponding y values.

Next, we need to find the points of intersection between the two curves. These are the x values where the two curves cross each other and have the same y value. To find these points, we will set the two equations equal to each other and solve for x:

=> x=5x−x³

Expanding this equation, we get

=> 4x³+x=0.

Factoring this equation, we get

=> x(4x²+1)=0.

This gives us two solutions, x=0 and x=±i√(1/4), where i is the imaginary unit. Since x can only take on real values, x=0 is the only solution that is an integer.

The graph of the new function would be less steep than the original one but would not be shifted up or down or left or right.

Thus, the correct option is: It would be less steep.

In mathematics, a graph is a visual representation of a set of objects where some pairs of the objects are connected by links. The objects, which are usually represented by points, are called vertices or nodes, and the links, which are usually represented by lines or arcs, are called edges.

The original function y = 5x + 1 has a slope of 5, which means that for every 1 unit increase in x, y increases by 5 units.

The new function y = 2x + 1 has a slope of 2, which is less steep than the slope of the original function.

However, the y-intercept of both functions is the same, which is 1.Therefore, the graph of the new function would be less steep than the original one but would not be shifted up or down or left or right.

Thus, the correct option is: It would be less steep.

Step-by-step explanation:

0.000000624 in scientific notation is 6.24 x \(10^{-7}\)

Answer:

Step-by-step explanation:

The resulting number is in scientific notation. In this case, the number is 6.24 * 10^-7.

The loss percentage is 91%.Given that Venessa bought 80 apples for 4$, out of these apples, 25% were rotten and had to be thrown away. Venessa sold the remaining apples at 6 cents per apple.To calculate the profit or loss percentage, we need to determine the cost price, selling price, and the number of apples sold.

Cost price (CP) = 4 $.Selling price (SP) = 80 × 0.75 × 6 cents= 36 cents = 0.36 $.Now, let's calculate the profit.Profit = SP – CP= 0.36 $ – 4 $= – 3.64 $Loss = CP – SP= 4 $ – 0.36 $= 3.64 $.

Therefore, Venessa incurred a loss of $3.64 when she sold 80 apples at 6 cents per apple.Now let's calculate the loss percentage Loss Percentage = (Loss / CP) × 100= (3.64 / 4) × 100= 91%.

Therefore, the loss percentage is 91%.Note: If the result obtained after the subtraction of SP from CP is negative, it means there is a loss, and the percentage of loss can be calculated by (loss/CP) × 100.

For Victor to have enough money to purchase the new iPhone 14 Pro Max, he will need to work for roughly 12 weeks.

An expression is made up of a number, a variable, or a combination of a number, a variable, and operation symbols. An equation is created by joining two expressions with an equal sign. For illustration: When you add 8 and 3, you get 11.

a) Here is the equation for Victor's savings account:

V(w) = 50w + 500

Slope (m) = 50

Y-intercept (b) = 500

b) The slope (m = 50) represents the rate at which Victor is saving money per week. For every week that he works as a tutor, he saves $50. The y-intercept (b = 500) represents the initial amount of money that Victor had saved up before he started working as a tutor.

(c)To find out how many weeks Victor will have to work to buy the new iPhone 14 Pro Max, we need to set up an equation where the amount of money he has saved up (V(w)) is equal to the price of the phone ($1099). Therefore, we can write:

50w + 500 = 1099

Subtracting 500 from both sides, we get:

50w = 599

Dividing both sides by 50, we get:

w = 11.98

Step-by-step explanation:

The cumulative relative frequency curve also known as Ogive is used for reading the median, upper quartile, lower quartile from the curve and calculating the semi-interquartile range when needed.

From the cumulative relative frequency curve, the interval with the highest proportion of measurements is the interval with the steepest slope. This is because the cumulative relative frequency curve always have a positive slope, and given that the interval has the highest proportion, then the slope will be steepest.

Answer:

The answer to this question would normally be, 85.96%, though that isnt an answer choice so the closest thing to it would most likely be answer choice A.

Using the binomial approximation to the normal, it is found that:

0.86 probability that at most 60 say yes, given by option a.

------------------------

Binomial probability distribution

Probability of exactly x successes on n repeated trials, with p probability.

The expected value is:

\(E(X) = np\)

The standard deviation is:

\(\sqrt{V(X)} = \sqrt{np(1-p)}\)

----------------------------

Normal probability distribution

Problems of normally distributed distributions can be solved using the z-score formula.

In a set with mean \(\mu\) and standard deviation \(\sigma\), the z-score of a measure X is given by:

\(Z = \frac{X - \mu}{\sigma}\)

When we are approximating a binomial distribution to a normal one, we have that \(\mu = E(X)\), \(\sigma = \sqrt{V(X)}\), if \(np \geq 10\) and \(n(1-p) \geq 10\).

----------------------------

The mean and standard deviation are given by:

\(\mu = E(X) = np = 87(0.64) = 55.68\)

\(\sigma = \sqrt{V(X)} = \sqrt{np(1-p)} = \sqrt{87(0.64)(0.36)} = 4.4771\)

Using continuity correction, the probability that at most 60 use is \(P(X \leq 60 + 0.5) = P(X \leq 60.5)\), which is the p-value of Z when X = 60.5, thus:

\(Z = \frac{X - \mu}{\sigma}\)

\(Z = \frac{60.5 - 55.68}{4.4771}\)

\(Z = 1.08\)

\(Z = 1.08\) has a p-value of 0.86.

Thus, 0.86 probability that at most 60 say yes, given by option a.

Drain pipe empty in 1 hour = 1/39

If both pipes are opened together then in pool fills in 1 hour =  1/38 - 1/39
