Answer: The range of the tree heights at yard work is greater than the range of the tree heights at the grow station

Step-by-step explanation:

yard works: 7,9,7,12,15

The grow station:9,11,6,12,7

mean of yard works = 7+9+7+12+15/5

=50/5=10

mean of grow station=

9+11+6+12+7 /5

=45/5 =9

The mean of tree heights at yard work is greater than that of grow station.

median(tree at yard work):7,7,9,12,15

median=9

median(tree at grow station)=6,7,9,11,12

median=9

The median of the tree height at yard work is equal to the median of that of tree station.

Range(yard work) = 15 - 7 =8

Range (tree station) =12-6=6

The range of the tree heights at yard work is greater to the tree heights at that of tree station

4. Simplify the following.<br>3<br>a. 2-X5-:11<br>3<br>x5<br>5<br>6<br>7

Ulleksa [173]

Answer:

Step-by-step explanation:

$2 \frac{3}{7} \times 5\frac{5}{6} \div 11 \frac{1}{3}$

Convert the mixed number to an improper fraction

$\frac{17}{7} \times \frac{35}{6} \div \frac{34}{3}$

To divide by a fraction, multiply the reciprocal of that fraction

$\frac{17}{7} \times \frac{35}{6} \times \frac{3}{34}$

Reduce the number with the G.C.F 7

$17 \times \frac{5}{6} \times \frac{3}{34}$

Reduce the numbers with the G.C.F 17

$\frac{5}{6} \times \frac{3}{2}$

Reduce the numbers with the G.C.F 3

$\frac{5}{2} \times \frac{1}{2}$

Multiply the fraction

$\frac{5}{4}$

In mixed fraction:

$1 \frac{1}{4}$

Hope this helps..
