Answer:
EBCG
Step-by-step explanation:
1) 50 - 87 = 23
2) 12 - 24= 288
3) 38.25 + 11.75= 50
4) 7 divided by 168= 24
Answer:
0.2684 is the probability that the temperature reading is between 0.50 and 1.75.
Step-by-step explanation:
We are given the following information in the question:
Mean, μ = 0 degrees
Standard Deviation, σ = 1 degrees
We are given that the distribution of thermometer readings is a bell shaped distribution that is a normal distribution.
Formula:

P(Between 0.50 degrees and 1.75 degrees)

0.2684 is the probability that the temperature reading is between 0.50 and 1.75.
Answer:
B and D
Step-by-step explanation:
The quadratic formula is
. Here a=20, b=-26, and c=8.
Substitute and you'll have:
This means the solutions are 26 - 6/ 40 and 26 + 6/ 40.
It simplifies to 1/2 and 4/5.
