Steph makes 90 % 90%90, percent of the free throws she attempts. She is going to shoot 3 33 free throws. Assume that the results of free throws are independent from each other. Let X XX represent the number of free throws she makes. Find the probability that Steph makes exactly 1 11 of the 3 33 free throws. You may round your answer to the nearest hundredth. P ( X = 1 ) =

Answers

Answer 1

Using the binomial distribution, it is found that there is a 0.027 = 2.7% probability that he makes exactly 1 of the 3 free throws.

For each free throw, there are only two possible outcomes, either he makes it, or he misses it. The results of free throws are independent from each other, hence, the binomial distribution is used to solve this question.

Binomial probability distribution

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]

The parameters are:

x is the number of successes. n is the number of trials. p is the probability of a success on a single trial.

In this problem:

He makes 90% of the free throws, hence [tex]p = 0.9[/tex].He is going to shoot 3 free throws, hence [tex]n = 3[/tex].

The probability that he makes exactly 1 is P(X = 1), hence:

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

[tex]P(X = 1) = C_{3,1}.(0.9)^{1}.(0.1)^{2} = 0.027[/tex]

0.027 = 2.7% probability that he makes exactly 1 of the 3 free throws.

Answer:

1) -2x - 3

2) -2a - 2

Step-by-step explanation:

Problem 1

To solve this problem, we only have to combine like terms. What are the like terms in this problem? Well, we have two x-terms (-10x and 8x) and two integers, or constants (1 and -4). So, let's rearrange the expression and then combine those terms.

-10x + 8x + 1 - 4

-2x - 3

Problem 2

This expression is a little more complicated since we have to distribute a 2 onto the two terms in the parentheses.

2(1 - a) - 4

2(1) - 2(a) - 4

2 - 2a - 4

Next, we can combine like terms.

-2a + 2 - 4

-2a - 2

Given that Harriet runs at a constant speed of 8 mph, at what time should she set off

Two airplanes leave an airport at the same time and travel in opposite directions. One plane travels 68 km/h faster than the other. If the two planes are 5052 kilometers apart after 3 hours, what is the rate of each plane?

Answers

Step-by-step explanation:

the slower plane travels x km in 3 hours.

the faster plane travels x + 3×68 = x + 204 km in 3 hours.

x + x + 204 = 5052 km

2x = 4848 km

x = 2424 km (in 3 hours).

so, the slower plane's speed is 808 km/h.

the faster plane's speed is 808 + 68 = 876 km/h.

______ seconds ​

Answers

Answer:

75 seconds

Step-by-step explanation:

The graph intersects the x axis at 75 seconds.  That means y = 0, and y is the amount remaining (in ml).

After 75 seconds the amount of slushy left in the cup becomes zero the answer is 75 seconds.

What is a line graph?

A line graph is a type of graph where the data points are connected by segments of straight lines.

We have a line graph shown in the picture.

Sean is drinking a slushy as fast as he can. The amount of slushy left in the cup (in milliliters) as a function of time (in seconds) is graphed.

As we can see the amount of slushy left in the cup is decreasing as the time increases.

At time = 75 seconds

The amount of slushy left in the cup = 0

Thus, after 75 seconds the amount of slushy left in the cup becomes zero the answer is 75 seconds.

Step-by-step explanation:

Let's solve for x ~

[tex] \sf \dfrac{1}{3} {x}^{2} + x + \dfrac{5}{3} {x}^{2} = \dfrac{1}{9} [/tex]

[tex] \sf \dfrac{(1 + 5)}{3} {x}^{2} + x = \dfrac{1}{9} [/tex]

[tex] \sf \dfrac{6}{3} {x}^{2} + x - \dfrac{1}{9} = 0[/tex]

[tex] \sf2 {x}^{2} + x - \dfrac{1}{9} = 0[/tex]

Multiply each term with 9 on both sides of the equation

[tex] \sf(2 {x}^{2} \times 9) + (x \times9 ) - ( \dfrac{1}{9} \times 9 ) = 0 \times 9[/tex]

[tex] \sf18 {x}^{2} + 9x - 1 = 0[/tex]

Now, let's use Quadratic formula to find its roots ~

[tex] \sf \dfrac{ - {b}^{} \pm \sqrt{b {}^{2} - 4ac} }{2a} [/tex]

where,

b is Coefficient of x = 9

a is Coefficient of x² = 18

c is the constant term = -1

Let's find the roots ~

[tex] \sf \dfrac{ - 9 \pm \sqrt{(9 {}^{2}) - (4 \times 18 \times - 1) } }{2 \times 18} [/tex]

[tex] \sf \dfrac{ - 9 \pm \sqrt{81- ( - 72) } }{36} [/tex]

The number of kilometers she will have left to run to finish the race is 0.9 km.

Given the following data:

Total distance = 13.5 kmSpeed = [tex]8\frac{2}{5} \;km/hr[/tex]Time = 1.5 hours

To determine the number of kilometers she will have left to run to finish the race:

First of all, we would calculate the distance she has covered by using this formula;

[tex]Distance = speed \times time\\\\Distance = 8\frac{2}{5} \times 1.5\\\\Distance = \frac{42}{5} \times \frac{3}{2} \\\\Distance = \frac{63}{5}[/tex]
