Question 1 (4 points)Data Set:
8.2, 9.3, 8.5, 8.8, 9.0
What is the mean, median and mode? Make sure to label each answer. Round any
decimals to the tenths place.
Would mean, median or mode be the best measure to describe the data?

Answers

Answer 1
Answer:

Answer:Mean = 8.7

Median= 8.8

Mode=Nil

Yes, they are the best measure to describe the data.

Step-by-step explanation:

Mean, otherwise known as average= total sum of data set/ number of data set

=45.8/5= 8.76

Median- the mid point data in a given set. We rearranged the data set in an ascending order to get the best measure. Median is 8.8

Mode- the most reoccurring number in a given data. For this data set, however, mode is not applicable as all each data value appears once

Triangle TUV is similar to triangle XYZ. Which of the following statements is true?

Answers

Answer:

Option B. The slope of VT is equal to the slope of ZX

Step-by-step explanation:

we know that

The formula to calculate the slope between two points is equal to

m=(y2-y1)/(x2-x1)

step 1

Find the slope VT

we have

V(-7,-3),T(-4,0)

substitute in the formula

m=(0+3)/(-4+7)

m=(3)/(3)

m_V_T=1

step 2

Find the slope ZX

we have

Z(0,4),X(6,10)

substitute in the formula

m=(10-4)/(6-0)

m=(6)/(6)

m_Z_X=1

therefore

The slope of VT is equal to the slope of ZX

Answer:

The slope of VT is equal to the slope of ZX.

Step-by-step explanation:

Two triangles are similar if the slopes of corresponding sides are equal.

In triangle TUV, TU is vertical, so the slope is undefined. The side UV is horizontal, so the slope is zero.

Determine the slope of the VT using the slope formula. Point V is at (-7, -3), and point T is at (-4, 0).

slope=y^2-y1/x^2-x1

=0-(-3)/-4-(-7)

=3/3

=1

In triangle XYZ, XY is vertical, so the slope is undefined. The side YZ is horizontal, so the slope is zero.

Determine the slope of the ZX using the slope formula. Point Z is at (0, 4), and point X is at (6, 10).

slope=y^2-y1/x^2-x1

=10-4/6-0

=6/6

=1

Compare the slopes of corresponding sides of the two triangles.

Sides TU and XY have undefined slopes.

Sides UV and YZ have zero slopes.

Sides VT and ZX have slopes of 1.

Therefore, the following statement is true.

The slope of VT is equal to the slope of ZX.

A worm travels 1250 millimeters.how many meters did the worm travel?

Answers

we know that

1\ meter=1,000\ millimeters

so

by proportion

(1)/(1,000)(m)/(mm) =(x)/(1,250)(m)/(mm) \n \n1,000*x=1,250\n \nx=1,250/1,000\n \nx=1.25\ m

therefore

the answer is

1.25\ m
m-meter\nmm-millimeter\n1m=1,000mm\to1mm=0.001m\n------------------\n\n1250mm=(1250\cdot0.001)m=1.250m=\boxed{1.25m}
