The conditional probability that, when flipping a non-biased coin four times, there are at least two heads, given that the first flip is a head, is 3/4.

Calculating the Conditional Probability:

Let us assume that getting a head in the first flip of coin is event B

Also, let us assume that getting a head in on of the remaining three flips is A

Then we have to find the probability of A given B, that is, P(A|B).

The formula for conditional probability is given as follows,

P(A|B) = P (A∩B) / P(B)

The probability of getting two heads, P(A∩B) = 3/8

The probability of getting head in the first flip, P(B) = 1/2

∴ P(A|B) = (3/8) / (1/2)

P(A|B) = 3/4

Thus,  the conditional probability of getting at least two heads, given that the first flip is a head is 3/4.

Since we are dealing with a proportion, it is determined by using the z-distribution that there is insufficient evidence to draw the conclusion that the proportion of all kochia plants that are resistant to glyphosate has increased because the test statistic is less than the critical value for the right-tailed test.

In this problem, we consider that:

[tex]$H_{0}: p_{2}-p_{1}=0$[/tex]

[tex]$H_{1}: p_{2}-p_{1} \neq 0$[/tex]

The proportions and standard errors are given by:

[tex]p_{1}=0.197, s_{1}=\sqrt{\frac{0.197(0.803)}{61}}=0.0509\\p_{2}=0.385, s_{2}=\sqrt{\frac{0.385(0.615)}{52}}=0.0675[/tex]

Hence, the distribution has mean and standard error given by:

[tex]\bar{p}=p_{2}-p_{1}=0.0675-0.0509=0.0166\\s=\sqrt{s_{1}^{2}+s_{2}^{2}}=\sqrt{0.0509^{2}+0.0675^{2}}=0.0845[/tex]

It is given by:

[tex]$z=\frac{\bar{p}-p}{s}$[/tex]

In which p = 0 is the value tested at the null hypothesis, hence:

[tex]z=\frac{0.0166}{0.0845}\\$z=0.2$[/tex]

The exponential growth function has:

When the function is reflected across the y-axis, we'll have no change to domain or range from what is described above.

Alissa is correct, the input values change to opposite, however the domain stays same - all real numbers.

It means Simon is correct with his statement.

The matching answer choice is C.

Answer:

Simon is correct because even though the input values are opposite in the reflected function, any real number can be an input.

Step-by-step explanation:

Exponential Function

General form of an exponential function:  [tex]f(x)=ab^x[/tex]

where:

If b > 1 then it is an increasing function

If 0 < b < 1 then it is a decreasing function

Reflection in the y-axis

[tex]y=f(-x) \implies f(x) \: \textsf{reflected in the} \: y \textsf{-axis}[/tex]

As the exponential function is a growth function, b > 1.

If the exponential growth function has been reflected in the y-axis, the x variable is negative:

[tex]\implies f(x)=ab^{-x}[/tex]

Regardless whether the initial value [tex]a[/tex] (y-intercept) is positive or negative, the domain of an exponential function is (-∞, ∞) so it is unrestricted.

Therefore, if the function is reflected across the y-axis, the output value for each input value will change, but the domain itself will not change and will still be all real numbers.

the statement which defines a translation is option A that is  "A translation proportionally stretches or compresses an object based on a given scale factor".

What is Translation ?

"Translation" moves points the same distance along lines that are parallel to each other.

Translation involves the initial object called the pre-image and the final object called the image. As you can see in the picture above, the rust-colored item represents the pre-image, and the blue item represents the image. Because of the arrow, we can tell the direction in which the image was moved. For other images, you may receive instructions on which image is the pre-image, or you may be asked to find the pre-image from the image.

Reflection, on the other hand, moves points along a specified line in such a way that the line bisects each line segment connecting corresponding pre-image points and image points.

Step-by-step explanation:

10 boys give their left hand

sry if im  wrong

There are 10 boys who give their left hand to a girl in the given scenario.

In a circle, the total number of students is equal to the sum of the number of boys and girls.

Therefore, in this case, there are 40 boys + 28 girls = 68 students in total.

Since exactly 18 boys give their right hand to a girl, there are 18 boys who are connected to girls in a clockwise direction. As the remaining boys are connected in a counterclockwise direction, the number of boys giving their left hand to a girl can be determined by subtracting 18 from the total number of girls.

Thus, the number of boys giving their left hand to a girl is 28 - 18 = 10 boys.

Therefore, there are 10 boys who give their left hand to a girl in the given scenario.

Answer:

Below in BOLD.

Step-by-step explanation:

5x^2 - 6x - 2 = 0

Quadratic formula for ax^2 + bx + c = 0  is

x =  [-b ± √(b^2 - 4ac)]/ 2a    

Here we have a = 5, b = -6 and c = -2

so x =  [-(-6)  ± √((-6)^2 - 4*5*-2)]/ 2*5

=  [ 6 ± √(36 + 40)] / 10

= 0.6 ±  √76 / 10

= 0.6 ±  0.8718

= 1.4718,  -0.2718

= 1.5, -0.3 to one decimal place.

x^2 + 3x = 40

x^2 + 3x - 40 = 0

We can factor this one:

(x - 5)(x + 8) = 0

x - 5 = 0 giving x = 5 and

x + 8 = 0 giving x = -8.

Answer  x = -8, 5.

Answer: definition of slope

Step-by-step explanation:

The results in step 7 come from substituting the coordinates into the slope formula.

Answer:

a.) An open circle on 4 with a solid line drawn to an open circle on -4.

Explanation:

Open circles are used for signs: < and >

Closed circles are used for signs: ≤ and ≥

Here in the given expression: |x| < 4

[<] sign is used so open circle is used

If |y| < a then -a < y < a

so here, -4 < x < 4

Both circles should be opened, drawn with a solid line from -4 to 4.

Answer:

[tex]\frac{1\cdot \left(4+\sqrt{3}\right)}{\left(4-\sqrt{3}\right)\left(4+\sqrt{3}\right)}\\[/tex]

[tex]1\cdot \left(4+\sqrt{3}\right)=4+\sqrt{3}[/tex]

[tex]\left(4-\sqrt{3}\right)\left(4+\sqrt{3}\right) = 13[/tex]

[tex]= \frac{4+\sqrt{3}}{13}[/tex]

x = 4

y = 3

z = 13

Answer:

x = 4, y = 3, z = 13

Step-by-step explanation:

Multiply the equation by the opposite of the denominator

[tex]\frac{(1)(4 + \sqrt{3}) }{(4-\sqrt{3})(4+\sqrt{3} ) } \\\\\frac{4 + \sqrt{3} }{16 - 4\sqrt{3} +4\sqrt{3} -3} \\\\= \frac{4+\sqrt{3} }{13}[/tex]

Step-by-step explanation:

1. Draw these points on a graph.

2. Point A is (4,5) and Point B is (7,-7).

3. You find the slope (gradient) by the Change in Height/ Change in Horizontal distance.

4. Now put that slope and one point into the "Point-Slope Formula"

5. Simplify Algebraically.

Answer:

y = - 4x + 21

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

calculate m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (4, 5 ) and (x₂, y₂ ) = (7, - 7 )

m = [tex]\frac{-7-5}{7-4}[/tex] = [tex]\frac{-12}{3}[/tex] = - 4 , then

y = - 4x + c ← is the partial equation

to find c substitute either of the 2 points into the partial equation

using (4, 5 )

5 = - 16 + c ⇒ c = 5 + 16 = 21

y = - 4x + 21 ← equation of line

Step-by-step explanation:

The equations:

2x – 3y = 10 → equ(1)

–4x + 6y = 20 → equ(2)

Using elimination method, and solving with y, we have:

3( –4x + 6y = 20) → equ(3)

6( 2x – 3y = 10) → equ(4)

Opening the bracket, we have:

–12x + 18y = 60

+12x – 18y = 60

From the above, we can see that both x and y are now eliminated, thereby giving us: 0 = 120 which makes no sense to me as it looks incorrect.
