Angles can be either straight, right, acute or obtuse. An angle is a fraction of a circle where the whole circle is 360°. A straight angle is the same as half the circle and is 180° whereas a right angle is a quarter of a circle and is 90°

hope this helped.

The scatterplot shown includes the (blue) least-squares regression line, whose equation is y = .975 + .005x, where y is calories

ziro4ka [17]

The scatterplot shown includes the (blue) least-squares regression line, whose equation is y = .975 + .005x, where y is calories (in thousands) and x is years after 1960. Choose the correct statement.

Answer: In the given regression equation, the calories are in thousands. Therefore, the slope 0.005 (0.005 x 1000 =5 calories) means the consumption is increasing at a rate of 5 calories per year.

Hence the option a. Consumption is increasing at a rate of 5 calories per year. is correct

3/8 x 2/6 x 4/8 x 5/12

Evgesh-ka [11]

Answer:

$\frac{5}{192}$

Step-by-step explanation:

$\frac{3}{8} * \frac{2}{6} * \frac{4}{8} * \frac{5}{12}$

Multiply all numerators

3 * 2 * 4 * 5 = 6 * 20 = 120

Multiply all denominators

8 * 6 * 8 * 12 = 48 * 96 = 4,608

$\frac{120}{4608}$

Simplify

$\frac{5}{192}$

Hope this helps :)

A lottery consists of one $2000 winner, three $500 winners, and ten $100 winners. a total of 1000 tickets are sold for $10 each.

Semenov [28]

Answer: -5.5

WOKINGS

Given that the lottery has the following number of winners:

One $2000 winner

Three $500 winners

Ten $100 winners

Also Given,

A total of 1000 tickets are sold

Each ticket costs $10

The expected winning for a person purchasing one ticket is the sum of the products of the gain/loss and their corresponding probability.

There is one $2000 winner

There are 1000 tickets

The probability of winning $2000

= 1/1000

= .001

There are three $500 winners

There are 1000 tickets

The probability of winning $500

= 3/1000

= .003

There are ten $100 winners

There are 1000 tickets

The probability of winning $100

= 10/1000

= .01

Since each ticket costs $10

Everyone who buys a ticket automatically loses $10.

Therefore, the probability of losing $10 is 1

Now to calculate the expected winning for a person purchasing one ticket

= 2000(.001) + 500(.003) + 100(.01) – 10(1)

= 2 + 1.5 + 1 – 10

= -5.5

The expected winning is -5.5. This implies that a person playing this lottery can expect to lose $5.50 for every one ticket that they purchase.
