You know when it is a periodic function if the values repeats in regular intervals or periods. An example of this is trigonometric functions that repeat over intervals of 2 pi radians.
Answer:
No I dont agree with Mai. As both the slug and snail are moving with constant speed.
Step-by-step explanation:
Given that:
A slug travels 3 centimeters in 3 seconds.
Speed of slug = distance/ time = 3/3 = 1 cms^-1
A slug travels 3 centimeters in 3 seconds.
Speed of snail = distance/ time = 6/6 = 1 cms^-1
Hence both have constant speeds only the time span for snail is increased which gives more distance it doesn't means that it had covered more distance.
i hope it will help you!
Answer:
see explaination
Step-by-step explanation:
Using the formulla that
sum of terms number of terms sample mean -
Gives the sample mean as \mu=17.954
Now varaince is given by
s^2=\frac{1}{50-1}\sum_{i=1}^{49}(x_i-19.954)^2=9.97
and the standard deviation is s=\sqrt{9.97}=3.16
b) The standard error is given by
\frac{s}{\sqrt{n-1}}=\frac{3.16}{\sqrt{49}}=0.45
c) For the given data we have the least number in the sample is 12.0 and the greatest number in the sample is 24.1
Q_1=15.83, \mathrm{Median}=17.55 and Q_3=19.88
d) Since the interquartile range is Q_3-Q_1=19.88-15.83=4.05
Now the outlier is a number which is greater than 19.88+1.5(4.05)=25.96
or a number which is less than 15.83-1.5(4.05)=9.76
As there is no such number so the given sample has no outliers
To find the answer,we can set an equation:
Let the time he used to drive in the afternoon be y miles.
Time used in the afternoon = y
Time used in morning = y - 70
Total time used = 248
The value of y:
y + (y - 70) = 248
2y-70 = 248
2y = 248+70
2y = 318
y = 318/2
y = 159
Therefore, he droved 159 miles in the afternoon.

100+(34-(4+2)*3)/4
=100+(34-6*3)/4
=100+(34-18)/4
=100+16/4
=116/4
=29
29 is the answer
