Outcome          Red     Blue    Green   Yellow
Frequency       10          5          13           7        total: 35 trials

experimental probability of Yellow: 7/35 =1/5 or 20%
experimental probability of Blue or Red: 5/35 + 10/35 = 15/35 = 3/7 or 42.86%

The sample is biased. This is because all he interviewed are employees of the company. They are more inclined to give a positive feedback regardless of their true opinion because they want to retain their jobs.

Graph the function represented in the table on the coordinate plane.
Umnica [9.8K]
First find out the function for the given table.
Find the slope.
m= (y2-y1)/(x2-x1)
m=(-1-(-3)) / (-1-(-2))
m=(-1+3) / (-1+2)
m=2/1
m=2
Now equation of line:
y-y1=m(x-x1)
y-(-3)=2(x-(-2))
y+3=2(x+2)
y+3=2x+4
y=2x+1
Now plot these points on the graph, we get the attached graph.

Derek is playing a prank on Grace and hid her pencil inside a tissue box that has a width of 4 inches, a length of 8 inches, and
ohaa [14]

Answer:

9.8 Inch

Step-by-step explanation:

The distance from the upper left corner to the bottom right corner of the box is the longest diagonal of the box.

For a rectangular prism:

Length of the Longest diagonal =\sqrt{ l^2+h^2+w^2}

Therefore:

Length of the pencil=\sqrt{ 8^2+4^2+4^2}

=\sqrt{96}\\=9.8$ inch(correct to  the nearest tenth of an inch)

A man earned x pesos in 10 days and spent y pesos during each of those days. Write an expression to determine how many pesos he
Vsevolod [243]

Answer:  \dfrac{x}{10}-y

Step-by-step explanation:

Given : A man earned x pesos in 10 days and spent y pesos during each of those days.

i.e. Total earning in 10 days = x

Earning per day =\dfrac{x}{10}    [By unitary method]    (1)

Money spent per day =y      (2)

We know that

\text{Savings = Money earned - Money spent}

i.e. Subtract (2) from (1), we get

\text{Savings = }\dfrac{x}{10}-y

Hence, the expression to determine how many pesos he saved per day will be:-

\dfrac{x}{10}-y

Solve the inequality 47. 75 x Less-than-or-equal-to 50 to determine how much more weight can be added to Li’s suitcase without g
vlada-n [284]

The value of x is less than or equal to 2.25.

<h2>Linear system</h2>

It is a system of an equation in which the highest power of the variable is always 1. A one-dimension figure that has no width. It is a combination of infinite points side by side.

<h3>Simplification</h3>

Simplification is to make something easier to do or understand and to make something less complicated.

Given

The expression is 47.75 + x ≤ 50.

<h3>To find</h3>

The value of x.

<h3>How to find the value of x?</h3>

The expression is 47.75 + x ≤ 50.

On simplifying,

47.75 + x ≤ 50

            x ≤  50 - 47.75

            x ≤ 2.25

Thus, the value of x is less than or equal to 2.25.

More about the linear system link is given below.
