Answer:

What is the probability both are math phobic​? 0.49%

What is the probability at least one is math phobic​? 9.31%

Step-by-step explanation:

In order to both be math phobic, both individuals has to be inside of the probability of 7%, that means 0.07*0.07 = 0.0049 = 0.49%

In order to at least one be math phobic there's some cases which satisfies the sentence:

Individual A is math phobic and B as well = 0.07*0.07 = 0.0049 = 0.49%

Individual A is math phobic, but B is not = 0.07*0.63 = 0.0441 = 4.41%

Individual A is not, but B is math phobic = 0.63*0.07 = 0.0441 = 4.41%

Suming the 3 possibles cases, the probability at least one is math phobic​

= 9.31%

I need help!<br><br>solve for x​
Volgvan

Answer:

x = 40

Step-by-step explanation:

Here's a fun fact, all of those angles actually add up to 360 degrees!

How do we know this? Well if you were to draw a small arc between each of the lines, you would see that the arc would end up making a circle. And remember, circles have 360 degrees!

Now we can do some basic algebra. Add up all the angles and set that equal to 360.

(2x) + (x) + (3x + 20) + (2x+20) = 360.

8x + 40 = 360

8x = 320

x = 40

Hope this helped!

Write the equation 12 − y = 2x − 5 in slope-intercept form. What are the slope and y-intercept? A. y=2x−17,m=2, y-intercept (0,−
MrRissso [65]

Answer:

D

Step-by-step explanation:

12-y=2x-5

+5        +5  ( add 5 to both sides)

17-y=2x

-17    -17  (Subtract 17 to get y by itself)

-y=2x-17

divide by -1 because y cant be negative

y=-2x+17

m=-2 and y-intercept= 17

I hope thats right :)
