Six different names were put into a hat. A name is chosen 125 times and the name Grace is chosen 17 times. What is the experimen

Elodia [21]

Answer:

Step-by-step explanation:

The experimental probability of choosing Grace is 13.6% (17/125*100)

The theoretical probability of choosing Grace is 16.67% (1/6)

Each probability would change because they depend on the data set so if the data set changes, that means the probability will also change depending on the amount it changes.

*1 A car is driving away from a crosswalk. The distance d (in feet) of the car from the crosswalk t

antoniya [11.8K]

Answer:

The change in the car's distance is 8 feet

Step-by-step explanation:

* Lets explain how to solve the problem

- A car is driving away from a crosswalk

- The distance d (in feet) of the car from the crosswalk t seconds

since the car started moving is given by the formula d = t² + 3.5

- The time increasing from 1 second to 3 seconds

- We need to now the change of the car's distance from the crosswalk

∵ The equation of the distance is d = t² + 3.5

∵ The time is 1 second

∴ d = (1)² + 3.5

∴ d = 1 + 3.5 = 4.5 feet

∵ The time is 3 seconds

∴ d = (3)² + 3.5

∴ d = 9 + 3.5 = 12.5 feet

∵ The change of the distance = d of 3 sec - d of 1 sec

∵ d of 3 sec = 12.5 feet

∵ d of 1 sec = 4.5 feet

∴ The change of the distance = 12.5 - 4.5 = 8 feet

∴ The change in the car's distance is 8 feet

Help please. with the steps on image.

Kipish [7]

Answer:

T(n) = 3n² - 4
-189 doesn't belong

Step-by-step explanation:

Given sequence:

-1, 8, 23, 44, 71

The first differences:

9, 15, 21, 27

The second differences:

6, 6, 6

If the sequence is T(n) = an² + bn + c, we have:

2a = 6 ⇒ a = 3

Using the first and second differences work out the value of zero term:

9 - 6 = 3
-1 - 3 = -4

This gives us c = - 4

Now we have:

T(n) = 3n² + bn - 4

The first term is T(1) = -1, substitute n = 1 and find the value of b:

3(1²) + b*1 - 4 = - 1
3 + b - 4 = - 1
b = 0

The nth term is:

T(n) = 3n² - 4

Now lets find if -189 belongs to this sequence:

- 189 = 3n² - 4
3n² = - 185

The left side is positive and the right side is negative so the answer is also negative
