Remember, -(-x)=x because the negatives cancel out

so
when p=-6 and q=7

p+(-q)-3
-6+(-7)-3
-6-7-3
-13-3
-16

Ellie needs new grass in the circular pen for her chickens. There is 175.84 feet of fencing around the circular pen. What is the

<h3>Area of pen is 2462 square feet</h3>

<em><u>Solution:</u></em>

Given that,

Ellie needs new grass in the circular pen for her chickens

There is 175.84 feet of fencing around the circular pen

Therefore,

Circumference = 175.84 feet

<h3><u>The circumference of circle is given as:</u></h3>

$C = 2 \pi r$

Where, "r" is the radius of circle

$175.84 = 2 \times 3.14 \times r\\\\175.84 = 6.28 \times r\\\\r = \frac{175.84}{6.28}\\\\r = 28$

<h3><u>The area of circle is given as:</u></h3>

$Area = \pi r^2\\\\Area = 3.14 \times 28^2\\\\Area = 3.14 \times 784\\\\Area = 2461.76 \approx 2462$

Thus area of pen is 2462 square feet

Employees were asked how many times per week they exercised. The frequency table shows the results of the survey.

wlad13 [49]

Answer:

See explanation

Step-by-step explanation:

Given the frequency table

$\begin {array}{cccccccccc}\text{Number}&0&1&2&3&4&5&6&7&8\\ \\\text{Frequency}&5&10&2&9&33&12&15&3&1\end{array}$

a) The total sum is

$5+10+2+9+33+12+15+3+1=90$

Create a probability distribution table

$\begin {array}{cccccccccc}\text{Number}&0&1&2&3&4&5&6&7&8\\ \\\text{Probability}&\dfrac{5}{90}&\dfrac{10}{90}&\dfrac{2}{90}&\dfrac{9}{90}&\dfrac{33}{90}&\dfrac{12}{90}&\dfrac{15}{90}&\dfrac{3}{90}&\dfrac{1}{90}\end{array}$

b) The probability

$P(x$

c) The probability

$P(x=6)=\dfrac{15}{90}=\dfrac{1}{6}$

d) The probability

$P(x\ge 5)=P(x=5)+P(x=6)+P(x=7)+P(x=8)=\dfrac{12}{90}+\dfrac{15}{90}+\dfrac{3}{90}+\dfrac{1}{90}=\dfrac{31}{90}$
