1 orange. Cuz 2 divided by 2 is 1
Given:
Pool swimming Ocean swimming Total
Age 30 and younger 228 54 282
Over 30 years old 142 185 327
total 370 239 609
Frequencies:
Pool swimming Ocean swimming Total
Age 30 and younger 228/609 = 0.37 54/609 = 0.09 282/609 = 0.46
Over 30 years old 142/609 = 0.23 185/609 = 0.30 327/609 = 0.54
<span>total 370/609 = 0.61 239/609 = 0.39 609/609 = 1.00</span>
<span>The relative frequency (rounded to the nearest hundredth) of a person over 30 years old who prefers to swim in the ocean is 0.30</span>
2.
EXPLANATION:
If g= 3 we can replace g with 3.
Now we have h-5 x 3
and if h= 17, we can replace h with 17.
Now we have 17 - 5 x 3.
because of pemdas, multiplication is first
5 x 3 is 15,
17 - 15 is 2.

While x is the number of small shakes and y is the number of large shakes each size shake you by needs to be multiplied by the cost .... D: 3x+5y=479
S + 2.8 = 6.59
s = ?
To solve for s use the inverse operation of addition, which is subtraction.
s + 2.8 = 6.59
6.59 - 2.8 = s
6.59 - 2.8 = 3.79
s = 3.79
Check:
s + 2.8 = 6.59
s = 3.79
3.79 + 2.8 = ?
3.79 + 2.8 = 6.59
Correct!
This proves: s = 3.79 ;)
