On a game show, a contestant randomly chooses an envelope and wins
the prize that is written inside. There are 3 envelopes containing a car,
5 envelopes containing a vacation, and 2 envelopes containing
electronics.
What is the probability that a contestant picks a vacation?

Answer:

See Explanation

Step-by-step explanation:

Let us assume that [tex] 5\sqrt 7[/tex] is a rational.

Therefore, it can be expressed in the form of [tex] \frac{p}{q}[/tex], where p and q are integers.

[tex] \implies 5\sqrt 7=\frac{p}{q}[/tex]

[tex] \implies \sqrt 7=\frac{p}{5q}[/tex]

[tex] \because [/tex] p and q are integers.

[tex] \therefore \frac{p}{5q}[/tex] is a rational number.

[tex] \implies \sqrt 7[/tex] is rational ([tex] \because [/tex] quotient of a rational number is rational)

But, it contradicts the fact that [tex]\sqrt 7[/tex]is irrational.

So, [tex]5\sqrt 7[/tex] is also irrational, because the product of rational and irrational is irrational.

This contradiction is arising out because of our wrong assumption that [tex] 5\sqrt 7[/tex] is rational.

Hence, [tex] 5\sqrt 7[/tex] is irrational.

Answer:

Positive (+) * positive (+) = +

Negative (-) * negative - = +

Negative (-) * positive (+) = -

Positive (+) * negative (-) = +

Step-by-step explanation:

How result of the product of two numbers are affected by the sign on each number being multiplied :

Signs on number values may be positive (+) or negative (-)

The rules goes thus :

Positive (+) * positive (+) = +

Negative (-) * negative - = +

Negative (-) * positive (+) = -

Positive (+) * negative (-) = +

Therefore for any tow rational numbers, the sin of their product will follow the rules above.

Answer:

$52

Step-by-step explanation:

first 2/3*156 and you get 104

Then you do 156 -104 and you will have your answer

Answer:

Max has $52 remaining

Step-by-step explanation:

[tex]\frac{2}{3}*\frac{156}{1} = \frac{312}{3} \\[/tex]

simplify [tex]\frac{312}{3}[/tex] by 3 to get [tex]\frac{104}{1}[/tex]

Distance Formula:

The distance between two points is the length of the path connecting them. The shortest path distance is a straight line. In a 2 dimensional plane, the distance between points (X1, Y1) and (X2, Y2) is given by the Pythagorean theorem:

d=(x2−x1)2+(y2−y1)2−−−−−−−−−−−−−−−−−−√

Calculate Distance

To calculate the distance between 2 points, (X1, Y1) and (X2, Y2), for example, (5, 6) and (-7,11), we plug our values into the distance formula:

d=(−7−5)2+(11−6)2−−−−−−−−−−−−−−−−−√

combining terms inside parentheses we get:

d=(−12)2+(5)2−−−−−−−−−−−√

squaring both terms we get,

d=144+25−−−−−−−√

adding the 2 results,

d=169−−−√

finally,

d=13

Answer:

x = 154°

Step-by-step explanation:

The central angle and the angle between the tangents are supplementary, so

x + 26° = 180° ( subtract 26° from both sides )

x = 154°

Answer:

24 800cm.

Step-by-step explanation:

Length in metres =12×100=12000cm

Perimeter. =2[l+b]

Perimeter. =2[12000+400]

Perimeter. =2×12400

Perimeter. =24 800cm

Perimeter. =24 800cm÷100

Perimeter. =24.8m

The cost of bill is,

⇒ $24

A number or ratio that can be expressed as a fraction of 100 or a relative value indicating hundredth part of any quantity is called percentage.

To Calculate the percent of a number , divide the number by whole number and multiply by 100.

Given that;

A 15% tip on a restaurant bill is $3.60.

Now,

Let the cost of bill is, $x

Hence, We can formulate;

⇒ 15% of x = 3.60

⇒ 15x/100 = 3.60

⇒ 15x = 360

⇒ x = 360 / 15

⇒ x = 24

Thus, The cost of bill is, $24

Answer:

Becky ran farther and farther by 560 ft.

Step-by-step explanation:

1 mile = 5280 ft

Becky: 2 * 5280 = 10560 ft

Keith: 10000 ft

10560 ft > 10000 ft, so Becky ran more distance than Keith.

10560 - 10000 = 560 ft, so Becky ran 560 ft more than Keith.
