Y-intercept means x=0 but judging from the question you only gave f(x) which means Y
And so I think the only valid answer there is
Y= 0.25
X=0
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>
Question a:
f(6) = (6)² + 2(6) + 8
f(6) = 36 + 12 + 8
f(6) = 56
Question b:
f(x+4) = (x+4)² + 2(x+4) + 8
f(x+4) = x² + 8x + 16 + 2x + 8 + 8
f(x+4) = x² + 10x + 32
Question c:
f(-x) = (-x)² + 2(-x) + 8
f(-x) = x - 2x + 8
Answer:
10*5 = 7x
Step-by-step explanation:
We can solve using cross products
10*5 = 7x
50 = 7x
divide each side by 7
50/7 =7x/7
50/7 =x
Answer:
(a)6.82mph
(b)22 ft/sec
Step-by-step explanation:
Eric's Speed = 10 ft/sec
The Ferry's Speed = 15 miles per hour
<u>Conversion Unit</u>
- 1 mile = 5280 feet
- 1 hour = 3600 seconds
<u>Guide</u>
- When converting from a smaller unit to a larger unit we divide
- When converting from a larger unit to a smaller unit we multiply
(a)To convert Eric's Speed 10 ft/sec to miles per hour
(b)To convert the Ferry's Speed 15 mph to ft/sec
