What is the slope of the line m?

Answer:

1. Yes, the table shows a probability distribution.

2. 0.39 males.

3. 0.6082 males.

Step-by-step explanation:

The random variable x is the number of males in the group who have a form of color blindness. Determine whether a probability distribution is given:

A probability distribution is given if the sum of all probabilities is 1.

We have that:

0.669 + 0.278 + 0.048 + 0.004 + 0.001 + 0 = 1

So yes, the table shows a probability distribution.

2. Find the mean of the random variable x.

We multiply each value by its probability. So

[tex]\mu = 0*0.669 + 1*0.278 + 2*0.048 + 3*0.004 + 4*0.001 + 5*0.000 = 0.39[/tex]

The mean is 0.39 males.

3. Find the standard deviation of the random variable x.

Square root of the subtraction squared of each value and the mean, multiplied by its respective probability. So

[tex]\sigma = \sqrt{0.669*(0-0.39)^2+0.278*(1-0.39)^2+0.048*(2-0.39)^2+0.004*(3-0.39)^2+0.001*(4-0.39)^2+0.000*(5-0.39)^2} = \sqrt{0.3699} = 0.6082[/tex]

The standard deviation is of 0.6082 males.

Answer:

50

Step-by-step explanation:

Given

first term (a) = 6

Common Difference (d) = 1 - 6 = - 5

Last term (tn )= - 239

Number of terms (n) = ?

We know

Tn = a + ( n - 1 ) d

- 239 = 6 + (n - 1) (-5)

- 239 = 6 - 5n + 5

- 239 = 11 - 5n

5n = 11 + 239

5n = 250

n  = 250 / 5

n = 50

The number of terms is 50.

Answer:

False im not sure sorry

Answer:

C. c(t) = 5 + 15t

Step-by-step explanation:

Well because the initial fee is $5, the answer must have the value of 5 without a variable next to it because this is the y-intercept.

(Only the slope will have the t next to it.)

Because $15 is charged EACH HOUR this would be the slope because there is a constant increase

Therefore c(t) = 5 + 15t

Answer:

C. c(t) = 5 + 15t

Step-by-step explanation:

She charges $15 per hour, so each hour (represented by "t") she earns 15 dollars. She also charges a $5 fee per germent. So she would get $5 plus 15 times however many hours she worked. So your answer would be c(t) = 5 + 15t.

DE : JK

= 21 : 7

= 1 : 3

The condition that proves congruent of two given triangles ΔDEF ∼ ΔJKL would be option A; DE : JK.

Two triangles are said to be congruent if the length of the sides is equal, a measure of the angles are equal and they can be superimposed.

we have given proof two triangles congruent by the postulate of SSS.

Since two corresponding sides of these triangles are congruent so additional third side should also be congruent to prove both the triangles congruent.

AC ≅ DF will complete the SSS property to prove both the triangles are congruent.

DE : JK

= 21 : 7

= 3 : 1

Answer:

Step-by-step explanation:

14: [tex]\frac{1}{2} = \frac{8}{1}[/tex]    [tex]\frac{x}{y} = \frac{56}{1}[/tex]

56/8 = 7 so multiply 1/2 by 7/1 to get the unidentified fraction "x/y"

1/2 · 7/1 = 7/2 or 3 1/2

15.  [tex]\frac{2}{5} = \frac{x}{100}[/tex]

to get from 100 to 5, you would divide by 20, so to solve for x, multiply 2 by 20, to get a product of 40.

40/100 = 40% or D

Hello!

[tex]\large\boxed{80 \text{ cookies}}[/tex]

To find the amount of cookies sold, we will need to divide the cost of each cookie from the total raised. Therefore:

Let c = cookies sold

60 = 0.75c

Divide both sides by 0.75:

60 / 0.75 = c

c = 80 cookies.

Answer:

4. y = 8 - x is the right answer

Answer:

4. y = 8 - x

Step-by-step explanation:

The question asks for which function is the ordered pair not a solution?

We need to substitute the ordered pair (4, 12) into x and y.

1. 12 = 3(4) (correct)

2. 12 = 16 - 4 (correct)

3. 12 = 4 + 8 (correct)

4. 12 = 8 - 4 (incorrect)

Therefore, the solution to your question is option 4.

Answer:

-a/(x+b)²

Step-by-step explanation:

Given the function y = a/x+b

To differentiate, we will use the quotient rule.

dy/dx = (Vdu/dx-Udv/dx)/V²

Let u   = a

v = x+b

Note that differential of a constant is zero

du/dx = 0

dv/dx = 1

Substitute

dy/dx = (x+b)0 - a (1)/(x+b)²

dy/dx = 0 - a/(x+b)²

dy/dx = -a/(x+b)²
