A bag contains 5 yellows tickets numbered 1 through 5. The bag also contains 5 green tickets numbers 1 to five. You randomly pic

MaRussiya [10]

Answer:

$\frac{3}{5}$ or 0.6

Step-by-step explanation:

Given:

Number of yellow tickets = 5

Number of green tickets = 5

Total number of tickets = 5 + 5 = 10

Required:

Find the probability that a randomly picked ticket is green or has a number greater than 4

Use the formula:

P = probability of green tickets + probability of yellow tickets with numbers greater than 4

Yellow tickets with numbers greater than 4 = 1 ticket

Probability of picking a green ticket = $\frac{5}{10} = \frac{1}{2}$

Probability of picking a yellow ticket with number greater than 4 = $\frac{1}{10}$

Therefore, probability that a randomly picked ticket is green or has a number greater than 4

= $\frac{1}{2} + \frac{1}{10} = \frac{6}{10}$

$= \frac{3}{5}$

Probability that a randomly picked ticket is green or has a number greater than 4 = $\frac{3}{5}$ or 0.6

What is the amplitude of y = 4sin3x? 1/2 2 3 4

liubo4ka [24]

The most generic sine function you can write is

$y = A\sin(\omega x + \phi) + k$

Of all these constant, $A$ affects the amplitude, $\omega$ affects the wave length, $\phi$ and $k$ cause horizontal/vertical translation.

In your case, $A = 4,\quad \omega = 3,\quad \phi = k = 0$

And we are interested in the amplitude, so we focus on $A = 4$

The amplitude of the standard sine function is 1, so when you multiply by $A$ , the new amplitude is $A$ itself. In our case $A = 4$ , so the amplitude is 4.

Answer:

They got 21 wins when they have 6 losses

Step-by-step explanation:

you need to multiply 2 by whatever will get you to 6.

2*3=6

and what you do to one side you do to another side.

7*3=21

The ratio is 21:6

If you need to fill the table, you can multiply two by two and two by 4

wins | 7 | 14 | 21 | 28 |

loss | 2 | 4 | 6 | 8 |

Emily's family loves to work together in the garden. They have a slight preference for flowers, as %60, percent of their plants

scoray [572]

Your answer is 20 vegetable plants. To answer this, you just need to find 40% of 50, as 40% of their total plants are vegetables. You can do this by dividing 50 by 10 to get 5, which is 10%, and then multiplying 5 by 4 to get 20, which is 40%.
I hope this helps!
