A study found that 36% of the assisted reproductive technology (ART) cycles resulted in pregnancies. Twenty-six percent of the ART pregnancies resulted in multiple births. (a) Find the probability that a random selected ART cycle resulted in a pregnancy and produced a multiple birth. (b) Find the probability that a randomly selected ART cycle that resulted in a pregnancy did not produce a multiple birth.(c) Would it be unusual for a randomly selected ART cycle to result in a pregnancy and produce a multiple birth?

Answers

Answer 1

In this case, we'll have to carry out several steps to find the solution.

Step 01:

Data:

assisted reproductive technology (ART) cycles:

pregnancies = 36%

pregnancies resulted in multiple births = 26%

Step 02:

a.

p (pregnancies) = 36% = 36/100 = 0.36

pregnancies resulted in multiple births = 26% = 26/100 = 0.26

p(pregnancies resulted in multiple births) = 0.36*0.26 = 0.0936

b.

p (pregnancy did not produce a multiple birth) = 1 - 0.0936 = 0.9064

c.

Indeed, the probability of multiple pregnancies is low 9.36%.

That is the full solution.

convert this number into scientific notation 0.00098

Answers

We have to convert the number into scientific notation.

The number is 0.00098.

We start by expressing it as a fraction.

If we divide it by 10, we can express it as:

[tex]\frac{0.00098\cdot10}{10}=\frac{0.0098}{10}[/tex]

Dividing by 10 is not enough. In the same way, we have to look a numerator that is multiple of 10 that gives us a numerator that is 9.8.

We would get:

[tex]\frac{0.00098\cdot10000}{10000}=\frac{9.8}{10000}[/tex]

Now we have the numerator we need.

We now express the denominator 10,000 as a power of 10 and we get the number in scientific notation as:

[tex]\frac{9.8}{10000}=\frac{9.8}{10^5}=9.8\cdot10^{-5}[/tex]

Answer: 0.00098 = 9.8 * 10^(-5)

How do i dilate a scale factor by 2?

Answers

The dilated figure is larger than the original figure if the dilation factor is greater than 1 and the dilated figure becomes smaller than the origial figure if the dilation factor is less than 1.

Since, the dilation factor is 2, the dilated image is larger than the original figure two times.

For the coordinate (x,y) in original figure, the coordiante in the dilated figure will be (2x,2y).

ifvx varies directly as y and x =36 when y=6 find x when y=9​

Answers

Answer:

54

Step-by-step explanation:

Hello!

A direct variation can be expressed as [tex]y = ax[/tex], where a is multiplied.

As you can see, x is 6 times greater than y, proving that when y is 6, x is 36 (6*6 = 36).

Therefore, we can say that if y is 9, we can multiply the value by 6 to find the x-value:

x = 6 * 9x = 54

So the value of x is 54.

White the standard form of the equation of the line through the given point with the given slope.

Answers

The standard form equation of a line is expressed as

Ax + By = C

where

A, B and C are real numbers and A and B are not both zero. From the information given,

the line passes through(- 2, 5) and slope = - 4

We would find the y intercept of the line, c by substituting slope, m = - 4, x = - 2 and y = 5 into the slope intercept equation which is expressed as

y = mx + c

Thus, we have

5 = - 4 * - 2 + c

5 = 8 + c

c = 5 - 8 = - 3

Thus, the equation of the line in the slope intercept form is

y = - 4x - 3

We would convert it to standard form. Thus, we have

y + 4x = - 3

4x + y = - 3

Thus, the equation in standard form is

4x + y = - 3

Madeline is a salesperson who sells computers at an electronics store. She makes a base pay of $80 each day and then is paid a $20 commission for every computer sale she makes. Make a table of values and then write an equation for P, in terms of x, representing Madeline's total pay on a day on which she sells x computers.

I need the Equation.

Answers

The linear equation that gives the values of P in terms of x which is Madeline's total pay on a given day is; P + 20·x + 80

What is an equation in mathematics?

An equation consists of two expressions that are joined by an equal to sign to complete a mathematical statement.

The given parameters are:

Madeline's daily base pay = $80

Madeline's commission for each computer sold = $20

The given table of values is presented as follows:

Daily pay, in Dollars, P;                     [tex]{}[/tex]        80, 100,  120, 140

Number of computers sold, x; [tex]{}[/tex]                 0,    1,       2,    3

From the above table of values, given that the independent variable, x, is increasing at a constant rate, and that the first difference is constant, we have that the relationship is a linear relationship, that has an equation of the form; P = m·x + c

Where:

m = The slope

c = The y-intercept

The slope which gives the ratio of the rise to the run of the graph is given by the equation; [tex]m = \dfrac{100-80}{1-0} =20[/tex]

The equation in point and slope form is therefore: P - 80 = 20·(x - 0) = 20·x

P - 80 = 20·x

P = 20·x + 80

So we need to figure out which is the best buy. In order to do this we must look at a particular variable: the price per ounce of peanuts. This price is given by dividing the total price of a certain amount of peanuts divided by its weight in ounces. So for the Barrel brand we get:

[tex]\frac{3.39}{10}=0.339[/tex]

So the Barrel peanuts cost $0.339 per ounce. For the Mr. Nut peanuts we get:

[tex]\frac{4.54}{14}=0.324[/tex]

Then the Mr. Nut peanuts cost $0.324 per ounce. Finally, the price per ounce of the Chip's peanuts is:

[tex]\frac{6.26}{18}=0.348[/tex]

Then, the cheapest peanuts are those of the brand Mr. Nut and that is the best buy.

Find the probability of at least 2 girls in 6 births. Assume that male and female births are equally likely and that the births are independent events.0.6560.1090.2340.891

Answers

We need to use Binomial Probability.

Of 6 births, we want to find the probability of at least 2 of them being girls.

To solve this, we need to find:

Probability of exactly 2 girls

Probability of exactly 3 girls

Probability of exactly 4 girls

Probability of exactly 5 girls

Probability of exactly 6 girls

If we add all these probabilities, we get the probability of at least 2 girls.

To find the probabilities, we can use the formula:

[tex]_nC_r\cdot p^r(1-p)^{n-r}[/tex]

Where:

n is the number of trials (in this case, the number of total births)

r is the number of girls we want to find the probability

p is the probability of the event occurring

[tex]_nC_r\text{ }is\text{ }the\text{ }combinatoric\text{ }"n\text{ }choose\text{ }r"[/tex]

The formula for "n choose r" is:

[tex]_nC_r=\frac{n!}{r!(n-r)!}[/tex]

Then, let's find the probability of exactly 2 girls:

The probability of the event occurring is:

[tex]P(girl)=\frac{1}{2}[/tex]

Because there is a 50% probability of being a girl or a boy.

let's find "6 choose 2":

[tex]_6C_2=\frac{6!}{2!(6-2)!}=\frac{720}{2\cdot24}=15[/tex]

Now we can find the probability of exactly 2 girls:

[tex]Exactly\text{ }2\text{ }girls=15\cdot(\frac{1}{2})^2(1-\frac{1}{2})^{6-2}=15\cdot\frac{1}{4}\cdot(\frac{1}{2})^4=\frac{15}{4}\cdot\frac{1}{16}=\frac{15}{64}[/tex]

We need to repeat these calculations for exactly 3, 4, 5, and 6 girls:

Exactly 3 girls:

let's find "6 choose 3":

[tex]_6C_3=\frac{6!}{3!(6-3)!}=\frac{720}{6\cdot6}=20[/tex]

Thus:

[tex]Exactly\text{ }3\text{ }girls=20\cdot(\frac{1}{2})^3(1-\frac{1}{2})^{6-3}=20\cdot\frac{1}{8}\cdot\frac{1}{8}=\frac{5}{16}[/tex]

Exactly 4 girls:

"6 choose 4":

[tex]_6C_4=\frac{6!}{4!(6-4)!}=\frac{720}{24\cdot2}=15[/tex]

Thus:

[tex]Exactly\text{ }4\text{ }girls=15\cdot(\frac{1}{2})^4(1-\frac{1}{2})^{6-4}=15\cdot\frac{1}{16}\cdot\frac{1}{4}=\frac{15}{64}[/tex]

Exactly 5 girls:

"6 choose 5"

[tex]_6C_5=\frac{6!}{5!(6-5)!}=\frac{720}{120}=6[/tex]

Thus:

[tex]Exactly\text{ }5\text{ }girls=6\cdot(\frac{1}{2})^5(1-\frac{1}{2})^{6-5}=6\cdot\frac{1}{32}\cdot\frac{1}{2}=\frac{3}{32}[/tex]

Exactly 6 girls:

"6 choose 6"

[tex]_6C_6=\frac{6!}{6!(6-6)!}=\frac{720}{720\cdot0!}=\frac{720}{720}=1[/tex]

Thus:

[tex]Exactly\text{ }6\text{ }girls=1\cdot(\frac{1}{2})^6(1-\frac{1}{2})^{6-6}=\frac{1}{64}\cdot(\frac{1}{2})^0=\frac{1}{64}[/tex]

now, to find the answer we need to add these 5 values:

[tex]\frac{15}{64}+\frac{5}{16}+\frac{15}{64}+\frac{3}{32}+\frac{1}{64}=\frac{57}{64}=0.890625[/tex]

To the nearest tenth, the probability of at least 3 girls is 0.891, thus, the last option is the correct one.

This horizontal line will intersect the function in a certain point. This point is where the function has the value 7.

Now, to find the value of x of this point, we draw a vertical line from this point downwards, until it intersects the x-axis.

This way, looking at the image, we can see that the value of x that gives us f(x) = 7 is the value x = 5.
