Use the distributive property to write an expression equivalent to 5 Times (3+4)

The distributive property states:

a(b+c) = ab + ac

Using that we get:

5\times (3+4)\\5(3+4) \\5(3) + 5(4)\\15 + 20\\35

You could also do it like:
5(3+4)\\5(7)\\35

So an expression that is equivalent to 5(3+4) is:

7(2+3)

That is your answer. It gets you the same final answer of 35.

Hope that helped :)

Answer:

No, these triangles are not similar.

Step-by-step explanation:

Similar triangles have the same angle measures.

Knowing that the angles in a triangle add up to 180 degrees, find the missing angle, and you will see that the angles in the triangle are not congruent to each other, meaning that the triangles are not similar.

Explain how to find the distance between two integers using the difference
jek_recluse [69]
When we want to find the distance between two integers using the difference, the best way is to plot them on number line. And then count distance between them. For example -3 and -1. But distance can not be negative.

On Friday night, the owner of Chez Pierre in downtown Chicago noted the amount spent for dinner for 28 four-person tables. 95 10
Shalnov [3]

Answer:

(a) The mean is 107.25, median is 106 and mode is 95.

(b) The data set is right-skewed.

Step-by-step explanation:

The sample space of amount spent for dinner for 28 four-person tables is:

S = {95, 103, 109, 170, 114, 113, 107, 124, 105, 80, 104, 84, 176, 115, 69, 95, 134, 108, 61, 160, 128, 68, 95, 61, 150, 52, 87, 136}

There are <em>n</em> = 28 values in the set.

(a)

The mean of this data set is:

\bar x=\frac{1}{n} \sum x=\frac{1}{28} \times3003=107.25

The mean is 107.25.

The data set consists of even number of observations.

The median for an even set of data is the mean of the middle two numbers.

First arrange the data set in ascending order:

52, 61 , 61 , 68 , 69 , 80 , 84 , 87 , 95 , 95 , 95 , 103 , 104 , 105 , 107 , 108 , 109 , 113 , 114 , 115 , 124 , 128 , 134 , 136 , 150 , 160 , 170 , 176

The median is the average value of the 14th and 15th observation.

Median=\frac{14^{th}obs.+15^{th}obs.}{2}=\frac{105+107}{2}=106

The median is 106.

The mode of a data set is the value with the most frequency.

Consider the arranged data set.

52, 61 , 61 , 68 , 69 , 80 , 84 , 87 , 95 , 95 , 95 , 103 , 104 , 105 , 107 , 108 , 109 , 113 , 114 , 115 , 124 , 128 , 134 , 136 , 150 , 160 , 170 , 176

The value 95 is repeated most of the times.

Thus, the mode is 95.

(b)

The value of mean, median and mode are related as follows:

Mean > Median > Mode

This implies that the data is skewed.

In case of a right-skewed data the Mean > Median > Mode.

In case of left skewed data the Mean < Median < Mode.

Thus, the data set is right-skewed.
