Step-by-step explanation:
the answer is
1) £30
2) £ 270
Answer:
The length of the base is 9 inches because area= basexheight which makes the base=270/30 in other words 9.
Step-by-step explanation:
Answer:
A) mean = 1.2
B) median
C) The measures of center use data points to approximate a middle value or average of a given data set
Step-by-step explanation:
The “balance” process was developed to provide another way in which the mean characterizes the “center” of a distribution.
The mean is the balance point of the data set when the data are shown as dots on a dot plot (or pennies on a ruler).
A) The balance point for the points 0.4, 1.4, and 1.8. Will be
(0.4 + 1.4 + 1.8)/3 = 3.6/3 = 1.2
B) The median is the measure of center that is indicated by the center of balance
The median is the value in the center of the data. Half of the values are less than the median and half of the values are more than the median. It is probably the best measure of center to use in a skewed distribution.
C) A measure of central (measure of center tendency) is a value that describe a set of data by identifying the central position of the data set. The three measures of central tendency are the mean, median and mode.
Given is :
The area of the rectangular patio is = 130 square feet
Let the width of the patio be = x feet
As length is 3 feet more than the width, so the length is = x+3 feet
Now area of rectangle is = length * width
This gives either x-10=0 or x+13=0
x-10=0 ; x=10
x+13=0 ; x=-13 (neglect this negative value)
So, the width of the patio is = 10 feet
Length = 10+3 = 13 feet
9 + (-4) = 5/2= 2.5
10 + 7 = 17/2 = 8.5
