At Noon, The Temperature At A Mountaintop Research Center Is 11 Degrees. Overnight The Temperature Drops

Answers

Answer 1

Answer: -30

Step-by-step explanation:

My answer is correct because, All you have to do is subtract all the numbers by 11 and the one that has the sum -19 is the correct choice. In this case -30 does and we can make sure were orrect by subtracting 11 by -19 and that equals -30.

Since there are no restrictions on the strings, we can think of this problem as drawing 5 random digits in sequence. There is a 9/10 chance each time we draw to NOT get a 4. Every time we draw, we multiply by 9/10 again until we've draw 5 digits. Thus, the answer is (9/10)^5 :)

Answers

Answer:

[tex]Pr = 0.59049[/tex]

Step-by-step explanation:

See Comment for Complete Question

Given that A has 5 digits. A digit in A can be chosen from 0 to 9 (10 digits).

However, selection without 4 means that we can only select from 0 to 3 and 5 to 9 (altogether, that is 9 digits)

The probability of selecting a number other than 4 in each of the digit is:

[tex]1st \to \frac{9}{10}[/tex]

[tex]2nd \to \frac{9}{10}[/tex]

[tex]3rd \to \frac{9}{10}[/tex]

[tex]4th \to \frac{9}{10}[/tex]

[tex]5th \to \frac{9}{10}[/tex]

So, the required probability is:

[tex]Pr = 1st * 2nd * 3rd * 4th * 5th[/tex]

[tex]Pr = \frac{9}{10} *\frac{9}{10} *\frac{9}{10} *\frac{9}{10} *\frac{9}{10}[/tex]

[tex]Pr = \frac{9^5}{10^5}[/tex]

[tex]Pr = \frac{59049}{100000}[/tex]

[tex]Pr = 0.59049[/tex]

the length of a rectangle is twice its width if the perimeter of the rectangle is 72 inches, find its area.

Answers

length = 2 x width

permiter = length x width x 2

perimeter = 72

72 ÷ 2 = 36

36 = 1 length and 1 width

(2 x width) + width = 36

width = x

2x + x = 36

3x = 36

x = 12

width = 12

length = 2 x width = 2 x 12 = 24

so

width = 12

length = 24

A wise man once said, "500 reduced by 4 times my age is 188." What is his age?

Answers

Answer:

125

Step-by-step explanation:

Answer:

He Is 78 Years Old.

Step-by-step explanation:

a = age

Solve for a in 500 - 4a = 188.

Simplify 500−4a=188.

500−4a=188

500+−4a=188

−4a+500=188

Subtract 500 from both sides.

−4a+500−500=188−500

-4a = -312

Divide both sides by -4.

[tex]\frac{-4a}{-4} =\frac{-312}{-4}[/tex]

a = 78

Answer:

He Is 78 Years Old.
