The mode is A. 3 because the mode is the number you see the most
Answer:
P (34<X<39) = 0.5899
Step-by-step explanation:
When the distribution is normal, we use 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 question, we have that:

What is the probability that a cat would return to it's dish between 34 and 39 times a day.
This is the pvalue of Z when X = 39 subtracted by the pvalue of Z when X = 34. So
X = 39



has a pvalue of 0.7486
X = 34



has a pvalue of 0.1587
0.7486 - 0.1587 = 0.5899
So
P (34<X<39) = 0.5899
Answer:
Step-by-step explanation:
We have pairs (5, 2550) and (8, 3300)
<u>Find the rate of change:</u>
- (3300 - 2550)/(8 - 5) =
- 750/3 =
- 250
$250 is the amount added to savings account every month
<u>Initial amount was:</u>
- 2550 - 5*250 =
- 2550 - 1250 =
- 1300
<u>Since the change is linear and we have y-intercept and slope, we can show the amount after x months as:</u>

Answer:
1 ≤ c ≤ 3
Step-by-step explanation:
In order to meet the standard, the chlorine level (c) must be at least 1 part per million (equal to or greater than 1):
1 ≤ c
At the same time, the level also needs to be no greater than 3 parts per million (equal to or lesser than 3)
c ≤ 3
Combining both inequalities yields (in parts per million):
1 ≤ c ≤ 3.
The compound inequality above describes the acceptable range for chlorine levels.
