Answer:
A
Step-by-step explanation:
A linear function describes a straight line with constant gradient. Hence A is the answer as it has a constant gradient of -1 .
B is wrong as the graph has an undefined gradient.
C is wrong as it has an increasing gradient.
D is wrong as it does not have a constant gradient too.
Hello,
The correct answer is B) 280 in²
= 10( 2 × 9 + 10 )
= 10 (2 × 9 = 18 + 10 = 28)
= 10 × 28 = 280
= 280
Answer: 280 in²
In other words.....
= 10(2*9+10)
= 10(18+10)
= 10*28
= 280
Answer: 280 in²
Hope this helps!!!! (:
Answer:
For the 99th percentile, we have X = 206 seconds.
Step-by-step explanation:
Problems of normally distributed samples can be solved using the z-score formula.
In a set with mean
and standard deviation
, the zscore of a measure X is given by:

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
In this problem, we have that:

99th percentile:
Value of X when Z has a pvalue of 0.99. So we use 




For the 99th percentile, we have X = 206 seconds.
Answer:
2, 6, 18, 54..
Step-by-step explanation:
2, 6, 18, 54...
2 x 3 = 6
6 x 3 = 18
18 x 3 = 54
54 x 3 = ...
