Answer:
72.91%, that is, approximately 73% of medium-sized dogs have a heart rate that is lower than Scooter's
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:
Lower than 126 beats per minute
pvalue of Z when X = 126. So
has a pvalue of 0.7291
72.91%, that is, approximately 73% of medium-sized dogs have a heart rate that is lower than Scooter's
Answer:
DE = 21
Step-by-step explanation:
Recall: the ratio of the corresponding side lengths of similar triangles are equal
Given that ∆ABC ~ ∆DEF, therefore,
AB/DE = BC/EF = AC/DF
AB = 8.4
DE = x
BC = 10
EF = 25
AC = 16.5
DF = 41.25
Let's find DE using AB/DE = BC/EF. Thus:
8.4/x = 10/25
Cross multiply
x*10 = 25*8.4
10x = 210
Divide both sides by 10
x = 210/10
x = 21
DE = x = 21
Answer: There is 100 ml in 0.1 liter.
Step-by-step explanation:
Since we have given that
the capacity of a beaker = 0.1 liter
As we know that
We need to change it into milimeters
Since, we know that liter is more than mililiter so we use the product operation.
so , there is 100 ml in 0.1 liter.
