The Wall Street Journal reported that Walmart Stores Inc. is planning to lay off employees at its Sam's Club warehouse unit. App

roximately half of the layoffs will be hourly employees (The Wall Street Journal, January 25-26, 2014). Suppose the following data represent the percentage of hourly employees laid off for Sam's Club stores. 55 56 44 43 44 56 60 62 57 45 36 38 50 69 65 a. Compute the mean and median percentage of hourly employees being laid off at these stores.

Answer:

The mean percentage of hourly employees being laid off at these stores is 52.

The median percentage of hourly employees being laid off at these stores is 55.

Step-by-step explanation:

Mean:

Sum of all values divided by the number of values.

So

M = \frac{55+56+44+43+44+56+60+62+57+45+36+38+50+69+65}{15} = 52

The mean percentage of hourly employees being laid off at these stores is 52.

Median:

Value that separate the lower 50% from the upper 50% in the sorted set.

The sorted set is

36 38 43 44 44 45 50 55

The set has cardinality 15, which is an odd number, so the median is the element at the position (15+1)/2 = 8 of the sorted set, which is 55.

The median percentage of hourly employees being laid off at these stores is 55.

The original point is (-3, -1), what is the new point after a translation of 3 units left and 4 units up?
Zielflug [23.3K]

Answer:

New point is ( - 6, 3).

Step-by-step explanation:

x= -3, after translation 3 units left, we get X = - 3 - 3 = - 6

y = -1, after translation 4 units up, we get X = -1 + 4 = 3

New point is ( - 6, 3).

Are the triangles similar? If so, state the similarity and the postulate or theorem that justifies your answer.
kow [346]

Answer: The triangles are not similar.

Step-by-step explanation:

Two figures are similar simply if they have the same shape, but not necessarily the same size. In a more mathematical sense, similar figures have the same angle measures and proportionate side lengths.

<em>For reference, side lengths are proportionate when the ratios between corresponding/matching sides are the same.</em>

Since we do not have any angles, we will try using the SSS Similarity Theorem, which states that if all three sides of both triangles are in proportion, then the triangles are similar. We will first list all the side lengths and match corresponding ones.

\triangle ABC \rightarrow 18,20,32\\ \triangle UVT \rightarrow 14,15,24

Since we matched corresponding sides, we can now check whether they have the same ratio).

\frac{18}{14}=\frac{20}{15}=\frac{32}{24}

\frac{9}{7}=\frac{4}{3}=\frac{4}{3}

Not all of the side lengths have the same ratio, so these triangles aren't similar. you must multiply 14 by 9/7 to get to 18, but you need to multiply the other two sides by 4/3 to get to their

Find the equation of a line, in slope-intercept form of a line that passes through the point (-5, -1) and is parallel to -2x+4y=
Lana71 [14]

Answer:

y=\frac{1}{2}x+\frac{3}{2}

Step-by-step explanation:

Let's write -2x+4y=8 to slope-intercept form.

We do this by solving for y

-2x+4y=8\\

Add 2x to both sides

4y=8+2x

Divide both sides by 4

y=\frac{1}{2} x+2

Now that we have that equation in slope-intercept form, the question wants us to find a line that is parallel to it that passes the point (-5, -1).

A line is parallel to another line is they have the same exact slope.

The slope is \frac{1}{2}.

Slope-intercept form: y=mx+b, where m is the slope and b is the y-intercept.

So, let's see what we have here so far.

y=\frac{1}{2}x +b

All we have to do is find b.

The question wants the line to pass the point (-5, -1).

Let's plug that point in.

-1=\frac{1}{2} (-5)+b\\-1=\frac{-5}{2}+b\\\frac{3}{2} =b\\

We have all the information needed to finish this problem!

So, the line that is parallel to -2x+4y=8 and passes through the point (-5, -1).

y=\frac{1}{2}x+\frac{3}{2}

Find the length of the altitude to the hypotenuse. round the answer to the nearest tenth, if needed.
Amiraneli [1.4K]

Answer : The correct option is, (B) 56.8

Step-by-step explanation :

Right Triangle Altitude Theorem:

The measure of altitude drawn from the vertex of the right angle of a right angled triangle to its hypotenuse is the geometric mean between the measures of the two segments of the hypotenuse.

We are drawing a line from vertex to hypotenuse side.

As per theorem:

\frac{BD}{AB}=\frac{CB}{AC}

\frac{BD}{60}=\frac{175}{185}

BD=\frac{175\times 60}{185}

BD=56.8

Therefore, the length of the altitude to the hypotenuse is 56.8

Use the discrimination and select whether the roots of 5x^2-4x+3=0 are real or non-real
Lelu [443]
With a=5, b= -4 and c=3, the discriminant is

16-4(5)(3) = 16-60, a negative number.  Thus, the roots are non-real (complex).
