Answer:

The corn plant grew by 11.17 inches during week 2.

Step-by-step explanation:

7 and 1/3 inches tall at the end of Week 1.

The height at the end of week 1, as a simple fraction, is:

$7 + \frac{1}{3} = \frac{3*7 + 1}{3} = \frac{22}{3}$

The corn plant was 18 1/2 inches tall at the end of Week 2.

At the end of week 2, the height will be of:

$18 + \frac{1}{2} = \frac{18*2+1}{2} = \frac{37}{2}$

How many inches did the corn plant grow during Week 2?

Height at the end of week 2 subtracted by the height at the end of week 1. So

$\frac{37}{2} - \frac{22}{3} = \frac{3*37-2*22}{6} = \frac{67}{6} = 11.17$

The corn plant grew by 11.17 inches during week 2.

Can someone help me? It's urgent and thank you!

Alex_Xolod [135]

Answer:

15.2%

Step-by-step explanation:

There are 12 marbles in total and there are 5 red marbles, so the probability of getting a red marble is 5/12. There are now 11 marbles and there are 4 blue marbles. So the probability of getting a blue marble is 4/11.

You multiply these 2 values together.

5/12 * 4/11 = 20/132 = 0.1515

This is about 15.2%
