Answer:

<h2>a) approximately 133 graduates</h2><h2>b) approximately 120°</h2>

Step-by-step explanation:

a) the number of graduates planning to continue studying :

= (37 1/2% + 12 1/2% + 16 2/3%) × 200

$=\frac{\left( 37\frac{1}{2} +12\frac{1}{2} +16\frac{2}{3} \right) }{100} \times200$

= (37.5 + 12.5 + 16.666666666667)×2

= 133.333333333334

…………………………………

b) the measurement of the angle representing those who plan to work :

= (360× 33 1/2)÷100

= (360× 33.333333333333)÷100

=119.999999999999

Answer:

There are <u>72 inches</u> in 6 feet.

Step-by-step explanation:

Given:

There are 12 inches in 1 foot.

Jada is working on improving her vertical jump.

Currently, her standing reach is 6 feet from the ground.

Now, to find the inches in 6 feet.

Let the inches in 6 feet be $x.$

As given:

In 1 foot there are 12 inches.

<em>So, 1 foot is equivalent to 12 inches.</em>

<em>Thus, 6 feet is equivalent to </em> $x$ <em />

Now, to find using cross multiplication method:

$\frac{1}{12} =\frac{6}{x}$

<em>By cross multiplying we get:</em>

$x=72$

So, the inches in 6 feet = 72.

Therefore, there are 72 inches in 6 feet.

Allisa [31]

Answer:

Step-by-step explanation:

Given

there are 50 winning number out of which 40 get $ 100 each and 10 wins $ 1000 .

let x denotes the winning from a randomly selected ticket

$x=100\ with\ Probability\ \frac{40}{5000}$

$x=1000\ with\ Probability\ \frac{10}{5000}$

Expected value is given by

$E(x)=100\times \frac{40}{5000}+1000\times \frac{10}{5000}$

$E(x)=0.8+2=2.8$

and Expected return is given by

$=100\times \frac{40}{5000}+1000\times \frac{10}{5000}-5$

$=2.8-5=$ -2.2$
