Step-by-step explanation:
Hello :)
The first one would be a rotation because it was easily rotated upward , it looks like it was rotated maybe 90°, The second one would be translation because it is simply moved upward and moved slightly to the right without be resized, rotated, or anything. The third one would definitely be a reflection because it appears to be flipped across the x axis. The fourth one i'm not really sure but i'm going to guess it is a rotation because it is turned in a different direction from the original figure.
Answer:
let the price of a glass of milk be m and the price of seafood dinners to be s
A. for the first equation , we can see that
3m+5s =38.5 ........1
and second equation
m+2s= 15.15........2
B. 3m+5s= 38.5 ......1
m+2s=15.15 .......2
using substitution method
make m subject in eqn 2
m= 15.15 - 2s
put m in eqn 1
3(15.15-2s) +5s=38.5
45.45 -6s+5s =38.5
-6s +5s =38.5 -45.45
-s= -6.95
divide both sides by -1
s = $ 6.95
m= 15.15 -2s
m= 15.15- 2(6.95)
m= 15.15 -13.9
m=$ 1.25
therefore the price of a glass of milk is $1.25 and the price of a seafood dinner is $6.95
To calculate the interquartile range of a dataset, we first arrange the dataset in order:
Since the given dataset is already arranged in order.
We obtain the Q1 and the Q3 data values.
The Q1 value is the value for which 25% of the datavalues lie below it. For the given dataset, the Q1 value is 24.
Similarly, the Q3 value is the value for which 25% of the datavalues lie above it. For the given dataset, the Q1 value is 28.9.
The interquartile range is given by
IQR = Q3 - Q1 = 28.9 - 24 = 4.9
Therefore, <span>the interquartile range (IQR) of the data set is 4.9.</span>
Answer:
The average rate of change of f(x) = x + 6 on [4,9) is 1.
Step-by-step explanation:
Given a function y, the average rate of change S of in an interval will be given by the following equation:
In this problem, we have that:
Interval [4,9]
Continuous function(no denominator or even root), this is why i can consider 9 a part of the interval for the calculation. So
.
So
The average rate of change of f(x) = x + 6 on [4,9) is 1.
