Total surface area: approximately 979.3 inches squared (total), 754.3 inches (lateral), and 225 inches (bottom)
Answer:
a. 17 b. 16/24
Step-by-step explanation:
a. Find the midpoints of each class interval which is:
7.5 x 2 = 15
12.5 x 9 = 112.5
17.5 x 5 = 87.5
22.5 x 5 = 112.5
27.5 x 3 = 82.5
Add all of these up to give 410
Add up the total of the frequency column which is 24
410 / 24 = 17.0833.....
Rounded to 2 significant figures, the answer is 17
b. Add together all the people under 20 which totals to 16 and put this over the total of 24 to give the fraction 16/24
Answer:
14/5
Step-by-step explanation:
That " • " signifies multiplication.
g(x) = (x + 1) / (x - 2) and h(x) = 4 - x are to be multiplied together to obtain (g·h)(x):
(x + 1)(4 - x)
(g·h)(x) = --------------------
x - 2
This could be simplified.
But our task is to evaluate this product function at x = -3. So we replace each instance of x with -3:
( -3 + 1 )( 4 - [-3] ) (-2)(7)
(g·h)(-3) = -------------------------- = ----------- = 14/5
-3 - 2 -5
You do 80km/1hr = n/3.75
Use this proportion to find that n=300
So, he drives 800km.
F(x) = 3x + 8
f(1) = 3 (1) + 8
f (1) = 3 + 8
f(1)= 11
