Answer:
a rectangular prism
Step-by-step explanation:
consists of 6 faces which are rectangles
1) Given that the apple tree is 4/5 pear tree we can write
Apple Tree size = 4/5 Peartree
Apple tree= 4m
2) So we can write the following expression for that:

So the Pear tree is 5 meters tall, and the apple tree is 4/5*5 = 4 m
1. IQR = Q3 - Q1 = 35 - 20 = 15
A. 15
3. The ages include 20 and 25 so A and C are out, and the ages are between the two ages
B. a >= 20 and a <= 25
4. With the addition of 30, there are now 14 dots. Therefore, the median will be the mean of the 7th and 8th dots from least to greatest on the number line. In this case, it would still be 22.
C. The median would stay the same.
Answer:
25%.
Step-by-step explanation:
We are asked to determine the percent of a data set is represented in
.
We know that 1st quartile or lower quartile of a data set represents 25% of data points. Median represents 50% of data points and upper or 3rd quartile represents 75%of data points of a data set.
Therefore, 25% of a data set is represented by 1st quartile (
).
Answer:
f^(-1) (x) = -(x+4)/7
Step-by-step explanation:
f(x) = - 7x-4
f(x)+4=-7x
x=-(f(x)+4)/7
f^(-1) (x) = -(x+4)/7
