Daniel spent $4.75 for a lunch and $1.85 for a snack
$4.75+$1.85=$6.6, so Daniel spent $6.6 total
Kyle spent $5.75 for lunch and $1.00 for a snack
$5.75+$1.00=$6.75, so Kyle spend total $6.75.
Final step:
$6.75-$6.6=$0.15. As a result, Kyle spent $0.15 or 15 cent more than Daniel. Hope it help!
The given expression is:
![\sqrt[4]{ 9^{ \frac{1}{2}x } }](https://tex.z-dn.net/?f=%20%5Csqrt%5B4%5D%7B%209%5E%7B%20%5Cfrac%7B1%7D%7B2%7Dx%20%7D%20%7D%20%20)
4th root is equivalent to raising the expression to power

. So, re-writing the expression by converting radical to exponent:
Therefore, the given expression simplifies to
Answer:
The relative frequency of mammals in the survey is 30%.
Step-by-step explanation:
Relative frequency is the ratio of the occurrence of a singular event and the total number of outcome
Amphibians Insects Fish Reptiles Birds Mammals
12 30 9 25 22 42
Relative frequency = 
Total number of wildlife animals = 12+ 30 +9 +25+22+42 = 140
Now the relative frequency of mammals in the survey = 
the relative frequency of mammals in the survey =
= 0.3
Converting into percentage , we get
=
= 30 %
