• changing an interior angle to a reflex angle

Step-by-step explanation:

In order for the outline of the polygon to have a pair of sides that is concave (pointed inward, rather than outward), the corresponding interior angle must be a reflex angle. (It must measure more than 180°.) Draw one; you'll see.

A game decreased in price by 2/3. After the reduction it was priced at £13. What was the original price of the game?

Archy [21]

Answer:

$x = 39$

Step-by-step explanation:

Based on the given conditions, write: $x=\frac{13}{1-\frac{2}{3}}$

Find common denominator and write numerators above common denominator: $x=\frac{\frac{13}{3-2} }{3}$

Calculate the sum or difference: $x=\frac{\frac{13}{1} }{3}$

Divide the fraction by multiplying its reciprocal: $x=13*3$

Calculate the product or quotient: $x=39$

Answer: $x=39$

A certain group of women has a 0.86% rate of red/green color blindness. If a woman is randomly selected, what is the probabil

Mariana [72]

Answer:

The probability that a randomly selected woman has red/green color blindness is 0.9914

Step-by-step explanation:

Given that the proportion of women having red/green color blindness is 0.86%

Represent that with p

$p= 0.86\%$

Convert proportion from percentage to decimal;

$p= \frac{0.86}{100}$

$p= 0.0086$

In probability; opposite probabilities add up to 1;

Let the probability that a woman selected have red/green color blindness be represented with q;

$p + q = 1$

Subtract p from both sides

$p - p + q = 1 - p$

$q = 1 - p$

Substitute 0.0086 for p

$q = 1 - 0.0086$

$q = 0.9914$

<em>Hence, the probability that a randomly selected woman has red/green color blindness is 0.9914</em>
