Answer:

2/3

Step-by-step explanation:

Ah, I see. A 1-6 die.

Probability of one number = 1/6

2 numbers? = 2/6

6/6-2/6=4/6

4/6=2/3

\huge{\boxed{\frac{2}{3}}}

There are 4 numbers on a number cube that are greater than 2. They are 3, 4, 5, 6.

Write this as a fraction. \frac{\text{4 favorable outcomes}}{\text{6 total outcomes}}

Divide both the numerator and denominator by 2 to simplify. \boxed{\frac{2}{3}}

How do you make a equivalent ratio?
GarryVolchara [31]
\bf Rowley\quad 16:14\implies \cfrac{16}{14}\qquad Rivera\quad 64:60\implies \cfrac{64}{60}
\\\\\\
\textit{so, simplifying both fractions }
\begin{cases}
\cfrac{16}{14}\implies \cfrac{8}{7}\\\\
\cfrac{64}{60}\implies \cfrac{16}{15}
\end{cases}\qquad \cfrac{8}{7}\ne \cfrac{16}{15}

A ball is launched at 30 meters per second (m/s) from a 20-meter tall platform. The equation for the object's height s at time t
Juliette [100K]

The maximum height the ball reaches is 65.92 m.

The time taken for the ball to reach the maximum height is 3.06 seconds.

The time taken for the ball to hit the ground is 6.12 seconds.

<h3>maximum height the ball reaches</h3>

The maximum height the ball reaches is calculated as follows;

s(t) = -4.9t² + 30t + 20

at maximum height, final velocity = 0

v = 0

ds/dt = -9.8t + 30 = 0

9.8t = 30

t = 30/9.8

t = 3.06 seconds

s(3.06) = -4.9(3.06)²  + 30(3.06)  + 20

s(3.06) = 65.92 m

Thus, the time taken for the ball to reach the maximum height is 3.06 seconds.

<h3>Time of flight of the ball</h3>

The time taken for the ball to hit is the total time of flight = 2 x 3.06 seconds = 6.12 seconds.

Thus, the maximum height the ball reaches is 65.92 m.

The time taken for the ball to reach the maximum height is 3.06 seconds.

The time taken for the ball to hit the ground is 6.12 seconds.

The graph of f*x)=2^(x+3) shifts 10 units to the right when it is replaced with the graph of f(x)=2^(x-k). What is the value of
kifflom [539]

Answer:

7

Step-by-step explanation:

f(x) = 2^(x + 3)

Shifted 10 units to the right:

f(x) = 2^(x + 3 − 10)

f(x) = 2^(x − 7)

Therefore, k = 7.
