A graphing calculator finds the regression line to be
  y = 5.5x + 52

lisov135 [29]3 years ago
4 0

Answer:

B. y=5.5x+52

Step-by-step explanation:

We are given the data set,

x                 y

2               65

4               74

6               81

8               96

10             109

Now, using the regression calculator, we get that,

<h3>The linear equation for that matches the data is y=5.5x+52.</h3>

So, option B is correct.

A car braked with a constant deceleration of 16ft/s2, producing skid marks measuring 200 feet before coming to a stop. How fast
Llana [10]

Answer:the car was traveling at a speed of 80 ft/s when the brakes were first applied.

Step-by-step explanation:

The car braked with a constant deceleration of 16ft/s^2. This is a negative acceleration. Therefore,

a = - 16ft/s^2

While decelerating, the car produced skid marks measuring 200 feet before coming to a stop.

This means that it travelled a distance,

s = 200 feet

We want to determine how fast the car was traveling (in ft/s) when the brakes were first applied. This is the car's initial velocity, u.

Since the car came to a stop, its final velocity, v = 0

Applying Newton's equation of motion,

v^2 = u^2 + 2as

0 = u^2 - 2 × 16 × 200

u^2 = 6400

u = √6400

u = 80 ft/s
