Sam has 2 brothers. His brothers are 5 cm shorter and 7 cm shorter than him. Sam's height is 140 cm. What is the median height o

pochemuha

Answer:

The median height of Sam and his brothers is 135.

Step-by-step explanation:

First, let's find the age of Sam's brothers:

$B_{1} = 140 cm - 5 cm = 135 cm$

$B_{2} = 140 cm - 7 cm = 133 cm$

The median height of Sam and his brothers is given by the middle number of the three values arranged from lowest to highest:

133 <u>135</u> 140

<em>Since the middle number is 135, then the median height is 135. </em>

Therefore, the median height of Sam and his brothers is 135.

I hope it helps you!

Yolanda owns 4 rabbits. She expects the number of rabbits to double every year.

klasskru [66]

It is geometric sequence.
Therefore:
$a_1=4\\
q=2\\
S=a_1*\frac{1-q^n}{1-q}\\
64=4*\frac{1-2^n}{1-2}\\
16=\frac{1-2^n}{-1}\\
-16=1-2^n\\
16+1=2^n\\
2^4+1=2^n\\
n>4$

After 4 yours she will have over 64 rabbits.
