Answer:

The probability of rolling a number greater than 2 two times in a row is arond 0.44

Step-by-step explanation:

Divide the number of events by the number of possible outcomes. This will give us the probability of a single event occurring. In the case of rolling a 3 on a die, the number of events is 1 (there's only a single 3 on each die), and the number of outcomes is 6.

Probability formula is the ratio of number of favorable outcomes to the total number of possible outcomes. Measures the likelihood of an event in the following way: - If P(A) > P(B) then event A is more likely to occur than event B. - If P(A) = P(B) then events A and B are equally likely to occur.

What is the length of the cylinder's height? Please help

raketka [301]

Answer:

Height = <u>9</u><u> </u>cm which means <u>Option </u><u>C </u>is the answer

Step-by-step explanation:

In the question we are given ,

Volume of cylinder = <u>2</u><u>2</u><u>5</u><u>π</u><u> </u><u>cm³</u>

Radius of cylinder = <u>5 cm</u>

And , we have to find the <u>height</u><u> of</u><u> </u><u>cylinder</u><u> </u>.

We know that ,

$\longrightarrow \pink{ \boxed{Volume \: of \: Cylinder = \pi r {}^{2}h }} \longleftarrow$

Our solution starts from here :

$\longmapsto \: \pi \: r {}^{2} h = 225\pi$

<u>Step </u><u>1</u><u> </u><u>:</u> Cancelling π with π :

$\longmapsto \: \cancel{\pi} \: r {}^{2} h = 225 \cancel{\pi}$

<u>Step </u><u>2</u><u> </u><u>:</u> Substituting value of radius which is 5 cm in the formula :

$\longmapsto \: (5) {}^{2} \times h = 225$

$\longmapsto \: 25h = 225$

<u>Step </u><u>3 </u><u>:</u> Transposing 25 to right hand side :

$\longmapsto \: h = \frac{225}{25}$

<u>Step </u><u>4</u><u> </u><u>:</u> Cancelling 225 by 25 :

$\longmapsto \: \red{\boxed{h = 9 \: cm}}$

<u>Henceforth</u><u> </u><u>,</u><u> </u><u>height</u><u> </u><u>of </u><u>cylinder</u><u> is</u><u> </u><u>9</u><u> </u><u>cm</u>

Given the functions f(x)= 1/x−4 +3 and g(x)=1/x+1 +6 .

melomori [17]

ANSWER

The graph shifts 5 units left and 3 units up.

EXPLANATION

The given functions are:

$f(x) = \frac{1}{x - 4} + 3$

and

$g(x) = \frac{1}{x + 1} + 6$

We want to transform f(x) so that, it coincide with the g(x).

The required transformation is

$f(x+5)+3$

Let us see why this works.

$f(x+5)+3 = \frac{1}{x + 5- 4} + 3 + 3$

$f(x+5)+3 = \frac{1}{x + 1} + 6 = g(x)$

The transformation f(x+5)+3 will shift f(x) 5 units left and 3 units up.

The third choice is correct.
