Which choice is equivalent to the quotient shown here when x is greater than or equal to 0?

Step-by-step explanation:

In the first three, the probability of success (or failure) is constant, so those distributions have binomial distributions.

The problem says nothing about doses, which most likely wouldn't be independent events anyways.

So the answer is indeed the first three.  Good job!

Answer: A . When the medicine is tried with two patients, X is the number of patients for whom the medicine worked.

B. When the medicine is tried with six patients, X is the number of patients for whom the medicine does not work.

C. When the medicine is tried with six patients, X is the number of patients for whom the medicine worked.

Step-by-step explanation:

From all the given options, option A, B and C has trials that have same probability of success for the given event X .

But option D shows event X is the number of doses each patient needs to take which varies depending on the patient.

Hence, the trials do not have same probability of success .

Answer:

Correct choice is (C). [tex]4z^5[/tex].

Step-by-step explanation:

Given expression is [tex]-3z^5-\left(-7z^5\right)[/tex].

Now we need to simplify that then select the correct difference value from the given choices.

[tex]-3z^5-\left(-7z^5\right)[/tex]

negative times negative is positive

[tex]=-3z^5+7z^5[/tex]

Combine like terms because variable z has same exponent.

[tex]=(-3+7)z^5[/tex]

[tex]=4z^5[/tex]

Hence correct choice is (C). [tex]4z^5[/tex].

Answer:

The predicted GPA is then y = 0.149(15) + 0.89 = 3.125

Step-by-step explanation:

Although you don't specifically say so, the equation you provide here is probably a "best fit" equation based upon data:  GPA versus number of hours of study per week.

Here, y = 0.149x + 0.89 and the number of study hours of interest is 15.

The predicted GPA is then y = 0.149(15) + 0.89 = 3.125

The GPA is 3.125 who studies for 15 hours a week if the line of the best fit is y=0.149x+0.89

A mathematical notion called the line of the best fit connects points spread throughout a graph. It's a type of linear regression that uses scatter data to figure out the best way to define the dots' relationship.

[tex]\rm m = \dfrac{n\sum xy-\sum x \sum y}{n\sum x^2 - (\sum x)^2}\\\\\rm c = \dfrac{\sum y -m \sum x}{n}[/tex]

We have a line of best fit:

y = 0.149x + 0.89

Plug x = 15 hours

y = 0.149(15) + 0.89

y = 3.125

Thus, the GPA is 3.125 who studies for 15 hours a week if the line of the best fit is y=0.149x+0.89

Answer:

[tex]\frac{b+3}{3}[/tex]

Step-by-step explanation:

[tex]\frac{b+3}{b} \div\frac{3}{b}[/tex]

We need to solve the above equation.

We replace the division sign by multiplication and reciprocated the second term

[tex]=\frac{b+3}{b} *\frac{b}{3}[/tex]

Multiplying both fractions:

[tex]=\frac{(b+3)*b}{3b}[/tex]

Cancelling b from numerator and denominator.

[tex]=\frac{(b+3)}{3}[/tex]

So, answer is:

[tex]\frac{b+3}{3}[/tex]

ANSWER

[tex]\frac{b + 3}{3}[/tex]

EXPLANATION

The given expression is

[tex] \frac{b + 3}{b} \div \frac{3}{b} [/tex]

We multiply the first fraction by the multiplicative inverse of the second fraction.

[tex]\frac{b + 3}{b} \times \frac{b}{3}[/tex]

We now cancel out the common factors to get:

[tex]\frac{b + 3}{3} [/tex]

Therefore simplified form is:

[tex]\frac{b + 3}{3} [/tex]

Answer: The radius

Step-by-step explanation:

The radius is the distance between the center point of the circle and a edge, it is half of the diameter which is the straight line passing through the center point.

Answer:

16. Angle C is approximately 13.0 degrees.

17. The length of segment BC is approximately 45.0.

18. Angle B is approximately 26.0 degrees.

15. The length of segment DF "e" is approximately 12.9.

Step-by-step explanation:

By the law of sine, the sine of interior angles of a triangle are proportional to the length of the side opposite to that angle.

For triangle ABC:

[tex]\displaystyle \frac{\sin{C}}{\sin{A}} = \frac{c}{a}[/tex].

[tex]\displaystyle \sin{C} = \frac{c}{a}\cdot \sin{A} = \frac{6}{26}\times \sin{103\textdegree}[/tex].

[tex]\displaystyle C = \sin^{-1}{(\sin{C}}) = \sin^{-1}{\left(\frac{c}{a}\cdot \sin{A}\right)} = \sin^{-1}{\left(\frac{6}{26}\times \sin{103\textdegree}}\right)} = 13.0\textdegree{}[/tex].

Note that the inverse sine function here [tex]\sin^{-1}()[/tex] is also known as arcsin.

By the law of cosine,

[tex]c^{2} = a^{2} + b^{2} - 2\;a\cdot b\cdot \cos{C}[/tex],

where

For triangle ABC:

Therefore, replace C in the equation with A, and the law of cosine will become:

[tex]a^{2} = b^{2} + c^{2} - 2\;b\cdot c\cdot \cos{A}[/tex].

[tex]\displaystyle \begin{aligned}a &= \sqrt{b^{2} + c^{2} - 2\;b\cdot c\cdot \cos{A}}\\&=\sqrt{21^{2} + 30^{2} - 2\times 21\times 30 \times \cos{123\textdegree}}\\&=45.0 \end{aligned}[/tex].

For triangle ABC:

Start by finding the cosine of angle B. Apply the law of cosine.

[tex]b^{2} = a^{2} + c^{2} - 2\;a\cdot c\cdot \cos{B}[/tex].

[tex]\displaystyle \cos{B} = \frac{a^{2} + c^{2} - b^{2}}{2\;a\cdot c}[/tex].

[tex]\displaystyle B = \cos^{-1}{\left(\frac{a^{2} + c^{2} - b^{2}}{2\;a\cdot c}\right)} = \cos^{-1}{\left(\frac{14^{2} + 6^{2} - 9^{2}}{2\times 14\times 6}\right)} = 26.0\textdegree[/tex].

For triangle DEF:

Apply the law of sine:

[tex]\displaystyle \frac{DF}{EF} = \frac{\sin{E}}{\sin{D}}[/tex]

[tex]\displaystyle DF = \frac{\sin{E}}{\sin{D}}\cdot EF = \frac{\sin{64\textdegree}}{39\textdegree} \times 9 = 12.9[/tex].

Answer:

  see below

Step-by-step explanation:

21) The law of sines can be used, since you have a side and its opposite angle.

  sin(F)/DE = sin(D)/EF

  F = arcsin(DE/EF·sin(D)) = arcsin(20/31·sin(95°)) ≈ 39.994°

  E = 180° -95° -39.994° ≈ 45.006°

  DF = sin(45.006°)/sin(95°)·31 ≈ 22.006

__

22) The remaining two problems can be solved using the law of cosines:

  c^2 = a^2 + b^2 - 2ab·cos(C)

Of course, c is the square root of the expression on the right.

  EF = √(19^2 +35^2 -2(19)(35)cos(61°)) ≈ √(941.203) ≈ 30.679

Then an angle can be found using the law of sines

  E ≈ arcsin(35/30.679·sin(61°)) ≈ 86.203°

  F ≈ 180° -61° -86.203° ≈ 32.797°

__

23) As in 22 …

  RS = √(20^2 +28^2 -2(20)(28)cos(91°)) ≈ √(1203.547) ≈ 34.692

  R ≈ arcsin(20/34.692·sin(91°)) ≈ 35.199°

  S ≈ 180° -91° -35.199° ≈ 53.801°

Set up a ratio for the area.

Area is squared so find the square root of the scale

√64/169 = 0.61538

Volume is cubed so cube the scale factor:

0.61538^3 = 0.23304

Multiply that by the volume:

4394 x 0.23304 = 1024

The volume of the smaller figure is 1,024 m^3

Answer:

Step-by-step explanation:

We know:

The ratio of the surface of two similar figures is equal to the square of the similarity scale. The ratio of the volume of two similar figures is equal to the cube of the similarity scale.

Therefore

k - similarity scale

[tex]k^2=\dfrac{64}{169}\to k=\sqrt{\dfrac{64}{169}}=\dfrac{\sqrt{64}}{\sqrt{169}}=\dfrac{8}{13}\\\\\dfrac{V}{4394}=\left(\dfrac{8}{13}\right)^3\\\\\dfrac{V}{4394}=\dfrac{512}{2197}\qquad\text{cross multiply}\\\\2197V=(512)(4394)\qquad\text{divide both sides by 2197}\\\\V=(512)(2)\\\\V=1024\ m^3[/tex]

Step-by-step explanation:

If C is the midpoint of KN, then KC = CN

So we can equate the expressions

[tex]KC= 2x+10[/tex]

[tex]CN= 4x+1[/tex]

KC = CN

[tex]2x+10=4x+1[/tex]

Subtract 2x on both sides

[tex]2x-2x+10=4x-2x+1[/tex]

[tex]10=2x+1[/tex]

Subtract 1 on both sides

[tex]9=2x[/tex]

Divide both sides by 2

[tex]x=4.5[/tex]

Now we find out KC

[tex]KC= 2x+10[/tex]

[tex]KC= 2(4.5)+10[/tex]

[tex]KC= 19[/tex]

Answer:

(x − 4)2 + ( y + 6)2 = 49

Step-by-step explanation:

The equation of a circle with center (h, k) and radius r is                                (x − h)2 + (y − k)2 = r2.

Define h, k and r using the given values. So, h = 4, k = −6 and r = 7.

Substitute the values into the equation of a circle:

(x − 4)2 + (y − (−6))2 =72

Simplify.

(x − 4)2 + (y + 6)2 = 49

Therefore, the equation of the circle B with center B(4, -6) and radius 7 is   (x − 4)2 + (y + 6)2 = 49.

The equation of the circle B with center B(4,−6) and radius 7 is[tex]\rm (x-4)^2+(y+6)^2=49[/tex], the corrcet option is B.

A circle can be represented as;

[tex]\rm (x-h)^2+(y-k)^2=r^2[/tex]

Where h and k are the centers of the circle and r is the radius of the circle.

The equation of circle B with center B(4,−6) and radius 7.

Substitute all the values in the equation

[tex]\rm (x-h)^2+(y-k)^2=r^2\\\\\rm (x-4)^2+(y-(-6))^2=7^2\\\\\rm (x-4)^2+(y+6)^2=49[/tex]

Answer:

24°

Step-by-step explanation:

The sum of the ratios is 30.  We know that the degree measure of a triangle is 180, so if we divide 180 by 3 we get increments of 6°.  That means that 4 parts algebraically can be expressed as 4(6°); 12 parts as 12(6°); 14 parts as 14(6°).  That gives us angles of 24°, 72°, 84°.  If we add those up we do indeed get 180°, so the smallest angle measure in that extended ratio is 24°

For this case we have by definition, that the equation of a line in the slope-intersection form is given by:

[tex]y = mx + b[/tex]

Where:

m: It's the slope

b: It is the cutoff point with the y axis

We have the following line:

[tex]2x-3y = 12\\2x-12 = 3y\\y = \frac {2} {3} x-4[/tex]

If the line we wish to find is perpendicular to the one given, then its slope is given by:

[tex]m_ {2} = \frac {-1} {m_ {1}}\\m_ {2} = \frac {-1} {\frac {2} {3}}\\m_ {2} = - \frac {3} {2}[/tex]

Then the line is:

[tex]y = - \frac {3} {2} x + b[/tex]

We substitute the point:

[tex]6 = - \frac {3} {2} (2) + b\\6 = -3 + b\\b = 6 + 3\\b = 9[/tex]

[tex]0.7x[/tex]

Equate them:

[tex]55+0.5x=0.7x\\ \\55=0.2x\\ \\550=2x\\ \\x=275[/tex]

Answer:

275 miles

Step-by-step explanation:

You can express the cost of each plan as follows:

Plan 1: 55+0.50x

Plan 2: 0.70x

x is the amount of miles driven

As you need to find the amount of miles where the two plans cost the same, you can equate them and solve for x:

55+0.50x= 0.70x

55= 0.70x-0.50x

55= 0.2x

x= 55/0.2

x= 275

Alan needs to drive 175 miles for the two plans to cost the same.

The Monday ratio was equal to the Tuesday ratio.

The Tuesday ratio was greater than the Wednesday ratio.

The Wednesday ratio was less than the Monday ratio.

Step-by-step explanation:

Using the ratio and Proportion concept, The true statements are:

The Monday ratio was equal to the Tuesday ratio.

What is Ratio?

Comparing two amounts of the same units and determining the ratio tells us how much of one quantity is in the other. Two categories can be used to categorize ratios. Part to whole ratio is one, while part to part ratio is the other. The part-to-part ratio shows the relationship between two separate entities or groupings. For instance, a class has a 12:15 boy-to-girl ratio, but the part-to-whole ratio refers to the relationship between a particular group and the entire. For instance, five out of every ten people enjoy reading. As a result, the ratio of the portion to the total is 5: 10, meaning that 5 out of every 10 persons enjoy reading.

What is Proportion?

Ratio and fractions are the main bases on which proportion is discussed. Two ratios are equal when they are expressed as a fraction in the form of a/b, ratio a:b, and then a percentage. In this case, a and b can be any two numbers. Ratio and proportion are important building blocks for understanding the numerous ideas in science and mathematics.

So, According to the question:

The ratio on Monday = [tex]\frac{12}{8}[/tex] = [tex]\frac{3}{2}[/tex]

The ratio on Tuesday = [tex]\frac{9}{6}[/tex] = [tex]\frac{3}{2}[/tex]

The ratio on Wednesday = [tex]\frac{6}{6}[/tex] = [tex]\frac{1}{1}[/tex]

So, from the above fraction, we can easily conclude that The Monday ratio was equal to the Tuesday ratio.
