<h2>Irregular Figure</h2>

$\normalsize\blue{\overline{\quad\quad\quad\quad\quad\quad\quad\quad\quad\quad\quad\quad\quad\quad\quad\quad\quad\quad\quad\quad\quad\quad \ \ \ }}$

Answer:

<h2>Figure Number 1.</h2><h2 />

Area of smaller square = $\tt\underline{5cm}$ $\tt{\times 5cm = }$ $\tt\underline\green{25}$ $\tt{sq.cm}$

Area of bigger square = $\tt{15cm \times}$ $\tt\underline{ 15cm }$ $\tt{=}$ $\tt\underline\green{225}$ $\tt{sq.cm}$

Total Area = $\tt\underline\green{25sq.cm}$ $\tt{+}$ $\tt\underline\green{225sq.cm}$ $\tt{=}$ $\normalsize \underline{\boxed{\tt \red{250}}}$ $\tt\underline{sq.cm}$

$\\$

<h2>Figure Number 2.</h2>

Area of square A = $\tt\underline{7m}$ $\tt{\times}$ $\tt\underline{7m}$ $\tt{=}$ $\tt\green{49}$ $\tt{sq.m}$

Area of square B = $\tt{7m}$ $\tt{\times}$ $\tt{7m}$ $\tt{=}$ $\tt\underline\green{49}$ $\tt{sq.m}$

Area of square B = $\tt{14m}$ $\tt{\times}$ $\tt\underline{14m}$ $\tt{=}$ $\tt\green{196}$ $\tt{sq.m}$

Total Area = $\tt\underline\green{49m}$ $\tt{+}$ $\tt\underline\green{49m}$ $\tt{+}$ $\tt\underline\green{196}$ $\tt{=}$ $\normalsize \underline{\boxed{\tt \red{294}}}$ $\tt{sq.m}$

====================================

To find the area of square use this formula $\large\tt{A = s \times s}$ . Means side of the square multiply to the same side of the square

$\normalsize\blue{\overline{\quad\quad\quad\quad\quad\quad\quad\quad\quad\quad\quad\quad\quad\quad\quad\quad\quad\quad\quad\quad\quad\quad \ \ \ }}$

The length of a flower garden is 9 meters. The width of the garden, w, is unknown. If the area of the garden is greater

muminat

Answer:

The width should be more than 5 m. So it can be 6,7 ...

Step-by-step explanation:

The length of a flower garden is = 9 m

The width of a flower garden is = w

The area of a flower garden > 45 sq. m

The area of a flower garden = l * b

l * b > 45

9 * b > 45

the width should be more than 5 m. So it can be 6,7 ...

An author receives a contract from a publisher, according to which she is to be paid a fixed sum of $20,000 plus $3.50 for each

Schach [20]

Answer:

The mean of the total payments she will receive is $79,500.

The standard deviation of the total payments she will receive is $14,000.

Step-by-step explanation:

Given : An author receives a contract from a publisher, according to which she is to be paid a fixed sum of $20,000 plus $3.50 for each copy of her book sold. The author judges that her uncertainty about total sales of the book can be represented by a random variable with a mean of 17,000 and a standard deviation of 4,000 books.

To find : The mean and standard deviation of the total payments she will receive ?

Solution :

Let 'x' represent total sales of the book.

Let 'y' represent the payment to the author.

According to question,

The mean of the total payments she will receive is given by,

$\mu_y=20,000+3.50\mu_x$
