Answer:
V = 141.37 cm³
Surface area = 150.80 cm²
i. Doubling the radius to 6 cm, while the height remains 5
Step-by-step explanation:
Given that :
Radius, r = 3cm
Height, h = 5cm
Volume , V of right cylinder :
V = πr²h
V = π * 3² * 5
V = 141.37166
V = 141.37 cm³
Surface Area :
2πr(h + r)
2 * π * 3(3 +5)
18.849555(8)
150.79644
= 150.80 cm²
Volume at r = 6 ; h = 5
V = π * 6² * 5
V = 565.48667 cm³
Volume at r = 3 ; h = 15
V = π * 3² * 15
V = 424.11500 cm³
To increase volume,
Answer:
y = 2/3x - 2
Step-by-step explanation:
y-intercept:
Point line crosses the y axis is -2 which is point (0, -2).
slope:
points (-3, -4) and (3, 0)
m = (y₂ - y₁) / (x₂ - x₁)
= (0 - (-4)) / (3 - (-3))
= 4 / 6
= 2/3
Equation of line using your y-intercept and slope from above:
y = mx + b
y = 2/3x - 2

Thats actually the answer believe it or not :)
Answer:
(c) The t-distribution is bell shaped
(e) The t-distribution has more values at the extremes than a standard normal distribution
(f) The t-distribution is centered at 0
Step-by-step explanation:
When the sample size is small or population variance is unknown, and we have to estimate population parameter then t- probability distribution is used.
The t-distribution has properties as follows:
- The mean of t-distribution is 0. Thus, option (f) is correct.
- t-distribution is normal. Thus, option (c) is correct.
- As compare to standard normal distribution, t-distribution has more values at the extremes. Thus, option (e) is correct.
