Mathematics
1 answer:
Sonja [21]3 years ago
8 0

The correlation coefficient of a scatter plot with line of best fit shown will be the slope of the line.

We can eliminate last 2 choices because the line is clearly a downward sloping line and it's slope wont be positive.

From the first two, it looks like the plot's slope is very close to -1. So we take -0.91, instead of -0.35. <em>[note: 0.91 is more steeper than 0.35 (which is very relaxed)]</em>


ANSWER: -0.91

Riders on a Ferris wheel travel in a circle in a vertical plane. A particular wheel has radius 20 feet and revolves at the const
Zarrin [17]

It will take a rider 10 seconds to travel from the bottom of the wheel to a point 10 vertical feet above the bottom.

The radius of the wheel is 20 feet it revolves at the constant rate of one revolution per minute

using cos function,

cos ∅ = \frac{\frac{R}{2} }{R}

= \frac{10}{20}

= \frac{1}{2}

∅ =60^{0}

we know that, 1 minute = 60 seconds = 360^{0}

1 second= 6^{0}

∴Time =\frac{60}{6}=10 seconds

Hence, it will take a rider 10 seconds to travel from the bottom of the wheel to a point 10 vertical feet above the bottom.
