Answer:

0.683 = 68.3% probability that a randomly chosen doctor is in favor of the vaccine

Step-by-step explanation:

(a) What is the probability that a randomly chosen doctor is in favor of the vaccine

75% of 115/250 = 0.46(German).

60% of 65/250 = 0.26(French).

65% of 70/250 = 0.28(Englishmen). So

[tex]p = 0.75*0.46 + 0.6*0.26 + 0.65*0.28 = 0.683[/tex]

0.683 = 68.3% probability that a randomly chosen doctor is in favor of the vaccine

Answer:

There are 1650 child visitors and 550 adult visitors

Step-by-step explanation:

Use this step by step that was already used before to answer this, it's a png file.

A system of linear equations that represents this situation is,

⇒ x + y = 2200

⇒ 6x + 9y = 14,850

Where, x represent the cost of a ticket for a child and let y represent the cost of a ticket for an adult.

A linear expression is an algebraic statement where each term is either a constant or a variable raised to the first power.

Given that;

Zoo admission costs $6 for children and $9 for adults.

And, On Monday, 2200 people visit the zoo and the zoo collects $14,850 in admissions.

Let x represent the cost of a ticket for a child and let y represent the cost of a ticket for an adult.

Hence, We can formulate;

A system of linear equations that represents this situation is,

On Monday, 2200 people visit the zoo.

So, we get;

⇒ x + y = 2200 .. (i)

And, Zoo admission costs $6 for children and $9 for adults and the zoo collects $14,850 in admissions.

So, We get;

⇒ 6x + 9y = 14,850 .. (ii)

If you're asking for x it's 10

Step-by-step explanation:

5x - 11 < 43

5x < 54

The maximum value of x is 10 (because 5x10<54)

a. Any number that is not the minimum or maximum could be removed without changing the range.

b. Removing the number 97 changes the range.

What is set ?

In mathematics, a set is a collection of distinct objects, called elements or members, that are treated as a single entity. Sets can contain any type of object, such as numbers, letters, or other mathematical objects.

To find a number that could be removed from the data set without changing the range, we need to determine the minimum and maximum values in the set. In this case, the minimum value is 53 and the maximum value is 97, so any number that is not the minimum or maximum could be removed without changing the range. For example, we could remove the number 85:

53 54 63 63

68 68 68 74

82 85 92 88

89 92 92 97

The range of the data set is still 97 - 53 = 44.

To find a number that could be removed from the data set that would change the range, we need to identify a number that is either the minimum or maximum value. For example, we could remove the number 97:

53 54 63 63

68 68 68 74

82 85 85 88

89 92 92

b. The range of the data set is now 92 - 53 = 39, which is smaller than the original range of 44.

Therefore, removing the number 97 changes the range.

Answer and Step-by-step explanation: This function is a probability density function of a random variable X:

[tex]f(x)=\frac{3(8x-x^{2})}{256}[/tex]

and to calculate probabilities, we will have to integrate it:

[tex]P(X<x)=\int\limits^x_0 {\frac{3}{256}(8x-x^{2}) } \, dx[/tex]

Solving:

[tex]P(X<x)=\frac{3}{256}(4x^{2}-\frac{x^{3}}{3} )[/tex]

Then:

a. P(X < 5)

[tex]P(X<5)=\int\limits^5_0 {\frac{3}{256}(8x-x^{2}) } \, dx[/tex]

[tex]P(X<5)=\frac{3}{256}(100-\frac{125}{3} )[/tex]

[tex]P(X<5)=\frac{3}{256}(\frac{300-125}{3} )[/tex]

[tex]P(X<5)=\frac{175}{256}[/tex]

P(X < 5) = 0.683

b. P(X < 9)

Since density function's upper limit is 8, probability of x < 9 is 100% or 1.

So, P(X < 9) = 1

c. P(5 < X < 7)

[tex]P(5<X<7)=\int\limits^7_5 {\frac{3}{256}(8x-x^{2}) } \, dx[/tex]

[tex]P(5<X<7)=\frac{3}{256}[4(7)^{2}-\frac{7^{3}}{3}-4(5)^{2}+\frac{5^{3}}{3}][/tex]

[tex]P(5<X<7)=\frac{3}{256}[96-\frac{218}{3} ][/tex]

[tex]P(5<X<7)=\frac{70}{256}[/tex]

P(5 < X < 7) = 0.273

d. P(X > 3)

[tex]P(X>3)=\int\limits^8_3 {\frac{3}{256}(8x-x^{2}) } \, dx[/tex]

[tex]P(X>3)=\frac{3}{256}[256-\frac{512}{3}-36+9 ][/tex]

[tex]P(X>3)=\frac{3}{256}(229-\frac{512}{3} )[/tex]

[tex]P(X>3)=\frac{175}{256}[/tex]

P (X > 3) = 0.683

e. P(X < x) = 0.95

[tex]0.95=\int\limits^x_0 {\frac{3}{256}(8x-x^{2}) } \, dx[/tex]

[tex]\frac{3}{256}[\frac{12x^{2}-x^{3}}{3} ] =0.95[/tex]

[tex]\frac{12x^{2}-x^{3}}{256}=0.95[/tex]

[tex]12x^{2}-x^{3}=243.2[/tex]

[tex]-x^{3}+12x^{2}-243.2=0[/tex]

Solving this cubic equation, we have three values for x:

x₁ = -3.909

x₂ = 8.992

x₃ = 6.917

The value of x will the one between 0 and 8, which are the limits of the function. So, value of x which gives a probability of 0.95 is x = 6.917.
