I found some possible answers:
A. “what do you think these cookies?”
B. “What is your opinion of these cookies?”
C. “How do you feel about these cookies?”
D. “How do you like these delicious cookies?”
Option D is the correct answer because the word "delicious" could effect the person's answer to benefit the cookies.
Answer:
a) We need to find p(x<68.15)
Standardize x to z, we have, z = (68.15-μ)/σ
=(68.15-57)/8.1
=1.38
Reading from standard normal tables,
p(z<1.38) =0.9162.
b) We need to find p(x>54.4)
Standardize x to z, we have, z = (54.4-μ)/σ
=(54.4-57)/8.1
=-0.32
Reading from standard normal tables,
p(z>-0.32) = 0.6255
The first I think I am not so sure
Answer:
Acceleration
Explanation:
Speed is how fast something moves.
Velocity is how fast it moves and in what direction it moves in.
Acceleration is the change in how fast it moves. I.e. if it speed up or slows down.
Here we are not given a speed, but are told that the subway car slows down (a negative change in speed), which is a change in speed, therefore it is acceleration (or more accurately deceleration as it is negative acceleration, slowing down, but acceleration is usually used to describe both.)
Hope this helped!
The hours it takes Kristen to travel the same distance Marian travelled is 19.5 hours.
The average speed of Marian is 65 miles per hour for 15 hours. Therefore, her distance travelled can be calculated as follows:
speed = distance / time
Therefore,
distance = time × speed
distance = 15 × 65
distance = 975 miles
Kristen travelled at an average speed of 50 miles per hour. Kristen covers the same distance with Marian. Therefore, the hours it takes Kristen to travel the same distance Marian travelled can be calculated as follows:
speed = distance / time
time = distance / speed
time = 975 / 50
time = 19.5 hours
