Find the missing coordinate so that the line through the point has the given slope

Color-blindness is any abnormality of the color vision system that causes a person to see colors differently than most people, o

creativ13 [48]

Answer: c) All of the above

Step-by-step explanation:

a) X=the number of color-blind males of the randomly chosen 20 individuals

Thus, X is binomial with n = 20 and p = 0.08.

Y represents the number of color-blind females of the randomly chosen 40 individuals

Thus, Y is also binomial with n = 40 and p = 0.01.

b) However, Z represents the total number of color-blind which is 60. The probability of being color-blind is not equal among all individuals as it is for X (0.08) and Y (0.09). Thus, Z is not binomial.

In conclusion both a and b are correct, which gives the correct answer number c) all of the above.

Answer:

The equation should be 2.5x+1.8=59.3

Step-by-step explanation:

First, subtract the 1.8 dollars from the 59.3. You will get 57.5. Divide it by 2.5 and you will get the number 21 as x.

Identify the x-intercept. 1) y= 1/5x + 3 2) y= 6x - 7 3) y= -8/3x + 9

irakobra [83]

1) 1/5x + 3=0

1/5x=-3

x=(-3)(5)=-15

2)6x-7=0

6x=7

x=7/6=1.17

3) -8/3x+9=0

-8/3x=-9

-8x=-27

x=27/8=3.375

Answer:

"A - $32.50"

Step-by-step explanation:

So, 0.40 per share for 100 shares is:

Decrease of 0.40 * 100 = $40

Also, 0.25 per share for 30 shares is:

Increase of 0.25 * 30 = $7.5

So, decreased by 40 and increased by 7.5 means Total Decrease of 40 - 7.5 = $32.5

Answer choice A is right.

Answer:

after 7 minutes
19,600 feet

Step-by-step explanation:

Here's the "pencil and paper" solution:

The two altitude equations are ...

y = 41300 -3100x
y = 2800x

They can be solved by setting the expressions for y equal to each other.

2800x = 41300 -3100x

5900x = 41300

x = 41300/5900 = 7

y = 2800·7 = 19600

The planes will both be at 19,600 feet after 7 minutes.

Attached are solutions from a graphing calculator, and from a calculator app that is able to solve systems of equations.

I find the graphing calculator the easiest to use. I can enter equations using a keyboard, and the solution is displayed in a form that can be copied and pasted.

The calculator app on my phone requires equation entry using a small on-screen keyboard, with multiple key hits required to access some functions. (y is obtained by hitting the x key twice, for example.)

The "pencil and paper" solution is not so difficult, but requires a certain amount of writing (or good short-term memory). The solutions for x and y require separate calculations, whereas the other methods give both x and y at the same time.
