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%

Answer:

x = 14

h^2 = p^2 + b^2\\h^2 =  7^2 + 12^2\\x^2 = 49 + 144\\x^2 = 193\\so, x = 13.89\\so, x = 14

Hello :)

We know that an answer in square feet would require us to calculate the area. In order to calculate the area of a rectangle, we multiply the length times the width. So, we have 6 x 2 which is 12 Therefore, the area is 12 square feet.

6[]

6+6+2+2=16

Have a nice day :)

(6x - 3) - (-3x + 2)
nadezda [96]

Answer:

Step-by-step explanation:

Simplifying

6x + -3 = (3x + -2)

Reorder the terms:

-3 + 6x = (3x + -2)

Reorder the terms:

-3 + 6x = (-2 + 3x)

Remove parenthesis around (-2 + 3x)

-3 + 6x = -2 + 3x

Solving

-3 + 6x = -2 + 3x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-3x' to each side of the equation.

-3 + 6x + -3x = -2 + 3x + -3x

Combine like terms: 6x + -3x = 3x

-3 + 3x = -2 + 3x + -3x

Combine like terms: 3x + -3x = 0

-3 + 3x = -2 + 0

-3 + 3x = -2

Add '3' to each side of the equation.

-3 + 3 + 3x = -2 + 3

Combine like terms: -3 + 3 = 0

0 + 3x = -2 + 3

3x = -2 + 3

Combine like terms: -2 + 3 = 1

3x = 1

Divide each side by '3'.

x = 0.3333333333

Simplifying

x = 0.3333333333
