STALIN [3.7K]

Answer:

1. 5/4

2. 7

Step-by-step explanation:

1) Lets call the width as w

Therefore length would be:

w+4

To find the perimeter you use the formula:

2 (l+w)

Now substitute our values into this formula:

2 (w+4+w)

2( 2w+4)

4w+8

Now make this equal to 13:

4w +8 = 13

4w = 5

w = 5/4

2. In this question we will call length l

Therefore width would be:

l-5

Now we will do the steps we did above:

2 (l+l-5)

2 (2l-5)

4l -10

4l - 10 = 18

4l = 28

l = 7

Cassie is a half pound of sugar in her cabinet her cake recipe calls for two tenths of a pound of sugar how many cakes can she m
mamaluj [8]
The information's given in the question should be very minutely checked. Based on those given information's the answer to the question can easily be deduced.
Amount of sugar in the cabinet of Cassie = 1/2 pound
Amount of sugar required by Cassie to make her cake recipe = 2/10 pound
                                                                                                   = 1/5 pounds
Then
The number of cakes that Cassie can make = (1/2)/(1/5)
                                                                        = 5/2
                                                                        = 2 1/2
So from the above deduction we can easily conclude that Cassie can make a total of 2 cakes with the sugar she has and there will still be some sugar left.

40 points fast For the following set of test scores, identify:
myrzilka [38]

Answer:

 The measure of center would this student want his teacher to use is the

median= {\bf 75}

Mean= {\bf 5}  ,  Mode={\bf 82}  , Range={\bf40}  and   Interquartile Range= {\bf 32}

Step-by-step explanation:

Given Data set= 50,55,70,75,82,82,90

Number of elements in data set= 7

To find Mean

The ‘Mean” is the average of a set of numbers.

The "Mean" is computed by adding all of the numbers in the data together and dividing by the number  of elements contained in the data set.

Mean= \frac{50 +55 +70 + 75 + 82 + 82 + 90} {7 }

Mean= \frac{504}{7}

Mean= 5

Median

The “Median” is the middle value of a set of ordered numbers.

Therefore Median=75

Mode

The "Mode" for a set of data is the value that occurs most often.

It is not uncommon for a data set to have more than one mode. This happens when two or more  elements occur with equal frequency in the data set.

Therefore Mode=82

Range

The "Range" is the difference between the largest value and smallest value in a set of data.

Range= 90-50

Range= 40

Interquartile Range

The “Interquartile Range” is the difference between smallest value and the largest value of the middle  50% of a set of data.

The "Interquartile Range" is from Q1 to Q3:

To find the interquartile range of a set of data:

The cut the list into four equal parts

. The quartiles are the “cuts”

The interquartile range is the distance between the two middle sets of data

Interquartile Range= Q_3-Q_1

Interquartile Range= 82-50

Interquartile Range= 32
