Answer:

0.10

Step-by-step explanation:

hello,

there are 5 answers and 2 are correct

I choose a first answer - the probability to be a correct one is 2/5

then now, there are 4 left answers and only 1 left is correct

the probability to choose the correct one is 1/4

so in total the probability to choose the 2 correct answers out of 5 is

$\dfrac{2}{5}*\dfrac{1}{4}=\dfrac{1}{10}$

which is 0.10

hope this helps

Translate the sentence into an inequality.

lord [1]

Answer:

2(W - 5) ≤ -29

Step-by-step explanation:

"Twice the difference of a number and 5 is at most -29" can be expressed symbolically as follows:

2(W - 5) ≤ -29

Further explanations:

"the difference of a number and 5" is W - 5, and thus "Twice the difference of a number and 5" is 2(W - 5).

"x ≤ -29" states "x is at most -29."

Which of the following are possible rational roots of the polynomial function f(x)=5x^2-3x+3

yanalaym [24]

You didn't post any option, but the ration roots theorem states that all possible rational roots of a polynomial come in the form

$\pm\dfrac{p}{q}$

where p divides the constant term and q divides the leading term of the polynomial. So, in your case, p divides 3 (i.e. it is 1 or 3), and q divides 5 (i.e. it is 1 or 5).

So, the possible roots are

$\pm 1,\quad \pm 3,\quad \pm\dfrac{1}{5},\quad \pm\dfrac{3}{5}$

For the record, this parabola has no real roots.

Using isosceles triangle theorems solve for x and y

klio [65]

Well lets start by getting y. We already know that all angles of a triangle will equal 180 degrees.
Therefore we know that 65 + 65 + y = 180. To solve for y we just add the two 65's then subtract that from 180
y = 180-130 = 50 Therefore y = 50

Now lets solve for x. We know that since angle B is flat it is equal to 180. The unknown value of angle B = 180 - 65
Therefore that unknown value = 115

As we previously stated all angles of a triangle equal 180. We can now come up with this equation: 115 + x + x = 180
2x = 65
x = 32.5
