Answer:
b. 2.28%.
Step-by-step explanation:
Mean temperatue (μ) = 1000°F
Standard Deviation (σ) = 50
°F
For any temperature value, X, the z-score is given by:
For X= 900°F
A z-score of -2.0 corresponds to the 2.28-th percentile of a normal distribution. Therefore, the probability that X<900 is:
Answer:
C AAA is not an accepted triangle congruence criterion
Step-by-step explanation:
AAA can be used to show similarity, but not congruence. At least one side must be involved in any triangle congruence claim.
__
The student could have made use of the fact that opposite sides are the same length, and used AAS or ASA to show congruence.
Let us assume the first even number = n
The second consecutive even number = n + 2
The third consecutive even number = n + 4
The addition of the three consecutive even numbers is 42 and it is already given in the question. Based on the information's given in the question, the answer can be easily deduced.
Then, the equation can be written as
n + (n + 2) + (n + 4) = 42
3n + 6 = 42
3n = 42 - 6
3n = 36
n = 36/3
= 12
So
The first even number = 12
The second consecutive even number = n + 2
= 12 + 2
= 14
The third consecutive even number = n + 4
= 12 + 4
= 16
So the three consecutive even numbers are 12, 14, 16.
Answer:
0.2+ <u>4.5</u> = 4.7
Step by step explanation:-
0.2+? =4.7
0.2 + x =4.7
x = 4.7-0.2
x = 4.5
Answer:
12.5 miles a hour
Step-by-step explanation:
12×5=60
12 min times 5 equal 60 min/ 1 hour
2.5×5=12.5
You run 2.5 miles in 12 minutes, so in order to find how far you run in an hour (which is 5 sets of 12 minutes), multiply 2.5 by 5
