22. Which is the interquartile range for
the city that has the
greater variability
in temperature?

Answer:

[tex]\sqrt{91}[/tex]  is irrational

Step-by-step explanation:

A rational number is a number that can be written as a ratio. Any whole number is rational number because it can be turned into a ratio.

The [tex]\sqrt{91}[/tex] is irrational.  

3 (or 3/1) is rational.

3/4 is rational

[tex]\sqrt{64}[/tex] = 8 and thus, is rational.

[tex]\sqrt{91}[/tex] = 9.539392014...... and is irrational

10.25 can be written as 41/4 so it's also rational.

This is based on my assumption you mistyped the 2 with the commas.

Answer:

10^4

Step-by-step explanation:

lets say the number is 1.0 if you where to move the decimal to the right 4 place the number would then be 10,000.0. basically if it says 10^4 add 4 0's

Moving the decimal point to the right 4 places in a number is the same as multiplying by 10⁻⁴.

The number system is a way to represent or express numbers.

A decimal number is a very common number that we use frequently.

Since the decimal number system employs ten digits from 0 to 9, it has a base of 10.

Any of the multiple sets of symbols and the guidelines for utilizing them to represent numbers are included in the Number System.

Let's consider a decimal number

2.23456 now multiply and divide by 10⁴

⇒ 2.23456 × 10⁴/10⁴

⇒ 22345.6/10⁴

⇒ 22345.6 × 10⁻⁴

Hence"Moving the decimal point to the right 4 places in a number is the same as multiplying by 10⁻⁴".

Answer:

1.18 times

Step-by-step explanation:

Given that :

Surface area of Lake Victoria = 26,828 sq miles

How much larger is the surface area of lake superior than that of like Victoria?

The surface area of Lake Superior = 31,700 sq miles

Hence, taking the ratio of the surface area of the two Lakes :

Lake Superior / Lake Victoria

31,700 / 26,828

= 1.1816013

Hence, the surface area of Lake Superior is 1.18 times larger than the surface area of Lake Victoria.

Answer: plz mark as brainliest

Step-by-step explanation:The table below shows the net effect of a person’s mental state and occupation on his or her truth telling.

Suppose that Dorothy is telling the truth. Then she is sane (and hence a pure mathematician) and Charlie is sane. Bob says that Charlie is insane, so Bob is not telling the truth. Since he says he’s pure, he’s actually applied and hence Charlie is telling the truth. But then he’s applied and sane applied mathematicians do not tell the truth. This is a contradiction.

Therefore, Dorothy is not telling the truth. Thus, both Charlie and Dorothy are insane (hence Dorothy is pure). Consequently, Bob is telling the truth. Therefore Bob is pure (and sane, since he is a truth teller). Since Charlie says that Bob is applied, he is not telling the truth. Since we know that he is insane, he must be pure.

Since Alice says that Charlie is pure, she is telling the truth. Therefore she is insane and consequently applied.

In summary:

Alice is an insane applied mathematician.

Bob is a sane pure mathematician.

Charlie is an insane pure mathematician.

Dorothy is an insane pure mathematician.

Alice: Alice claims to be insane. If she is telling the truth, then her belief is incorrect, and she is, in fact, sane.

Mathematicians and statisticians solve problems in industry, academia, and government by using formulas and data.

Alice: Alice claims that she is insane. If she's telling the truth, her belief is incorrect, and she's perfectly normal. Alice is thus either pure or applied.

Bob: Bob declares himself to be pure. Bob's belief is correct, and he is indeed pure, because pure mathematicians tell the truth.

Charlie claims to be applied, but Alice claims Charlie is pure. Alice's claim about Charlie is true because applied mathematicians lie, and Charlie is actually pure.

Dorothy: Dorothy asserts that she is sane. Dorothy's belief is correct, and she is indeed sane, because the beliefs of sane mathematicians are correct.

Therefore, the four mathematicians are Alice (either pure or applied), Bob (pure), Charlie (pure), and Dorothy (sane).

Complementary Angles:

Two angles that add up to 90.

Answer:

x = 8

Step-by-step explanation:

Solve for x:

x/4 = 12/6

Hint: | Reduce 12/6 to lowest terms. Start by finding the GCD of 12 and 6.

The gcd of 12 and 6 is 6, so 12/6 = (6×2)/(6×1) = 6/6×2 = 2:

x/4 = 2

Hint: | Multiply both sides by a constant to simplify the equation.

Multiply both sides of x/4 = 2 by 4:

(4 x)/4 = 4×2

Hint: | Cancel common terms in the numerator and denominator of (4 x)/4.

(4 x)/4 = 4/4×x = x:

x = 4×2

Hint: | Multiply 4 and 2 together.

4×2 = 8:

Really sorry for the second question

Answer:

no solution

Step-by-step explanation:

Given

2(x + 1) = 2x + 5 ← distribute parenthesis on left side

2x + 1 = 2x + 5 ( subtract 1 from both sides )

2x = 2x + 4 ( subtract 2x from both sides )

0 = 4 ← not possible

This indicates the equation has no solution

Answer:

See below

Step-by-step explanation:

● 2(x+1) = 2x +5

Multiply 2 by (x+1)

● 2x + 1×2 = 2x+5

● 2x + 2 = 2x+5

Substract 2x from both sides

● 2x+2-2x = 2x+5-2x

● 2 = 5

This is impossible, so this equation has no solution.

Please let me know if you have any question

Answer:

You have 3 pennies and your friend has 1 penny

Step-by-step explanation:

The given parameters are;

Let friend A = you

friend B = Your friend

The number of pennies with  friend A when he gives friend B 1 penny = Equal number of pennies between friend A and B

The number of pennies with friend A when he is given 1 penny by friend B = 2 times the number of pennies with friend B

Let the number of pennies with friend A = X and the number of pennies with friend B = Y, therefore, we have;

X - 1 = Y + 1.....................(1)

X + 1 = 2 × Y...................(2)

Subtracting equation (1) from equation (2), we get;

X + 1 - (X - 1) = 2·Y - (Y - 1)

X - X + 1 + 1  = 2·Y - Y + 1

2 = Y + 1

Y = 2 - 1 = 1

Y = 1

From equation (1), X - 1 = Y + 1 gives;

X - 1 = 1 + 1

X = 1 + 1 + 1 = 3

Friend A has 3 pennies and friend B has 1 penny.

Therefore, you have 3 pennies and your friend has 1 penny

Answer:

11/3 or 3 2/3 (sry if its wrong)

Step-by-step explanation:

Answer:

1.2, 3/5, 25%, 0.17, -12

Step-by-step explanation:

In order to put these from greatest to least, you must put these in like terms.

Since there are more decimals that other terms, we're going to convert them all to decimals.

25%= 0.25

0.17= 0.17

3/5= 0.60

1.2= 1.20

-12= -12.00

Now that we see which numbers are greater, we convert them back to their original terms and place them in order from greatest to least.

1.2, 3/5, 25%, 0.17, -12
