Answer: A. (72π - 144) mm²

<u>Step-by-step explanation:</u>

$A_{shaded}=A_{circle}-A_{square}\\\\\\A_{circle}=\pi \cdot r^2\\.\qquad \ =\pi \bigg(\dfrac{12\sqrt2}{2}\bigg)^2\\\\.\qquad \ =\pi (6\sqrt2)^2\\.\qquad \ =72\pi\\\\\\A_{square}=side^2\\.\qquad \quad =\dfrac{12\sqrt2}{\sqrt2}^2\\\\.\qquad \quad =12^2\\\\.\qquad \quad =144\\\\\\\large\boxed{A_{shaded}=72\pi-144}$

Work out(3^5-5^3+2) divided 4^2

professor190 [17]

Given:

$(3^5-5^3+2)$ divided by $4^2$ .

To find:

The simplified form of the given expression.

Solution:

We have, $(3^5-5^3+2)$ divided by $4^2$ . Mathematically it can be written as:

$\dfrac{3^5-5^3+2}{4^2}=\dfrac{243-125+2}{16}$

$\dfrac{3^5-5^3+2}{4^2}=\dfrac{120}{16}$

$\dfrac{3^5-5^3+2}{4^2}=\dfrac{15}{2}$

$\dfrac{3^5-5^3+2}{4^2}=7.5$

Therefore, the simplified form of the given expression is 7.5.

the diagram shows the repairs performed on 2 types of cars compare the car types using the median and the mean

mash [69]

Answer:

The correct option is 2.

Step-by-step explanation:

The box plot represents the minimum value, first quartile , median, third quartile and maximum value.

From the box plot of Roadsters is it notices that

$\text{Lower limit}=2$

$Q_1=3$

$Median=4$

$Q_3=5$

$\text{Upper limit}=9$

From the box plot of Bandits is it notices that

$\text{Lower limit}=2$

$Q_1=3$

$Median=4$

$Q_3=5$

$\text{Upper limit}=6$

From the these information we can say that the median of both cars is same but bandit have lower mean because all four values of both cars is same but the upper limit of bandit is less.

Therefore option 2 is correct.
