A group of friends spent 1, 0, 2, 3, 4, 3, 6, 1, 0, 1, 2, and 2 hours online last night. What are the 1st and 3rd quartiles for this set of data?

Answer:

14-6

Step-by-step explanation:

Answer:

she has 3 quarters

Step-by-step explanation:

let's call the amount of dimes D

let's call the amount of quarters Q

you know that she has 11 coins in total,

so D + Q = 11.

you also know that each dime is worth 10 cents.

and each quarter is worth 25 cents.

so 10d + 25q = 155

this is a system of equations. solve by substitution:

d = 11 - q

10d + 25q = 155

10(11 - q) + 25q = 155

110 - 10q + 25q = 155

15q + 110 = 155

15q = 45

q = 45/15

q = 3

Answer:

y = -0.25x + 2.25

Step-by-step explanation:

First, you can simplify the equation of the line it's perpendicular to (2y = 8x - 6) by dividing both sides by 2. This means you would get y = 4x - 3. From that you can conclude that the slope of that line is 4.

Lines always have a slope that is the negative reciprocal of the slope of the line they are perpendicular to, so you know the slope of the line is going to be -1/4.

So far, you have the equation y = -1/4x + b and you have to find b.

You can substitute in the point (-3, 3) so you would have 3= -1/4 * -3 + b

Solving,

3 = 3/4 + b

b = 2 and 1/4

Therefore the equation is y = -1/4x + 2 1/4 or y = -0.25x + 2.25

Answer:

It is B

Answer: 18 quarts

Step-by-step explanation:

Quantity of sparkling water and gape juice are used in proportion in  the recipe.

Let x=  quantity of sparkling water when 9 quarts of grape juice is used.

Then,

[tex]\dfrac{x}{9}=\dfrac{1\dfrac12}{\dfrac34}\\\\\Rightarrow\ =\dfrac{x}{9}=\dfrac{\dfrac32}{\dfrac34}\\\\\Rightarrow\ \dfrac{x}{9}=\dfrac{4}{2}\\\\\Rightarrow\ x= 2\times9\\\\\Rightarrow\ x=18[/tex]

Hence, 18 quarts of sparkling water is required to mix with 9 quarts of grape juice.

Answer:

$917

Step-by-step explanation:

Let the money be $x

x×(1+(8.75%/12))^(12)=1000

x=916.5097877016

x=917(cor.to 3 sig.fig.)

Answer

The answer is x > -8

Which of the following can be done by using conditional formatting?

Calculate quarterly sales.

Highlight all “no” responses.

Count the number of students in high school.

Calculate average scores on a math test.

Conditional formatting applies formatting to cells if specific conditions are met. For example, conditional formatting can be used to apply background color to “no” responses in a customer satisfaction survey. This will allow the business owner to quickly locate and read customer complaints and identify areas for improvement.

Conditional formatting involves applying cell formats to certain cells, if and only if they meet certain criteria.

Highlighting all "no" responses can be done using conditional formatting.

Options (a), (c) and (d) are all direct calculations that can be executed using Microsoft Excel functions and formulas such as:

However, option (b) indicates that;

The cell is to be highlighted

And the condition for highlighting the cell is that:

The content of the cell is "no"

By comparing the above analysis to the meaning of conditional formatting, we can conclude that, conditional formatting can only be applies to option (b).

Answer:

It is positive (9)

Step-by-step explanation:

Negative ÷ negative = positive

Negative ÷ positive = negative

positive ÷ positive = positive

positive ÷ negative = negative

Negative × negative = positive

negative × positive = negative

positive × positive = positive

Positive × negative = negative

If both symbols are the same, it is positive. If one is positive and one is negative (different symbols), it is negative.

The result is 9. Since both the divisor (-3) and the dividend (-27) are negative, the final result is positive.

When dividing -27 by -3, the result is positive. In this case, the negative signs cancel out each other, and two negatives make a positive.

To understand why, think of division as the process of finding out how many times one number (divisor) can fit into another number (dividend). In this case, we are trying to find out how many times -3 can fit into -27.

-27 ÷ (-3) = 9

Here's the step-by-step calculation: -3 times 9 equals -27, which matches the dividend. So, the result is 9.

Since both the divisor (-3) and the dividend (-27) are negative, the final result is positive.

In conclusion, -27 divided by -3 is positive 9.

Answer:

The two friends meet at [tex]8:20 \:\text {am}[/tex].

Step-by-step explanation:

Given: Two friends live [tex]7[/tex] miles apart. The two friends set out on their bikes at [tex]8[/tex] am and started riding towards each other one rides at [tex]0.2[/tex] miles per minute, and the other rides at [tex]0.15[/tex] miles per minute.

To find: The time when the two friends meet.

Solution:

Distance between two friends [tex]=7 \:\text{miles}[/tex]

Speed of one friend [tex]=0.2 \:\text{miles per minute}[/tex]  

Speed of other friend [tex]=0.15 \:\text{miles per minute}[/tex]

Since, both are riding towards each other, the net speed will be [tex]0.2+0.15=0.35 \:\text {miles per minute}[/tex].

We know that,  [tex]\text{time}=\frac{\text{Distance}}{\text{Speed}}[/tex]

So, time taken to cover [tex]7 \:\text{miles}=\frac{7}{0.35} =20 \:\text{minutes}[/tex]

Now, both the friends set out on their bikes at [tex]8[/tex] am and started riding towards each other. So, the two friends meet after [tex]20[/tex] minutes.

Hence, the two friends meet at [tex]8:20 \:\text {am}[/tex].

We'll solve this equation:

First, let's apply the distributive property:

‎      ‏‏‎5x + 17 = 4(3x - 1)

‎      ‏‏‎5x + 17 = 12x - 4

Now, add 4 to both sides of the equation:

‎      ‏‏‎5x + 17 = 12x - 4

5x + 17 + 4 = 12x - 4 + 4

‎      ‏‏‎5x + 21 = 12x

Substract 5x from both sides:

‎  ‎     ‏‏‎5x + 21 = 12x

5x - 5x + 21 = 12x - 5x

‎      ‏‏‎‎      ‏‏‎‎   21 = 12x - 5x

‎      ‏‏‎‎      ‏‏‎‎   21 = 7x

Now, divide both sides by 7

‎      ‏‏‎‎   21 ÷ 7 = 7x ÷ 7

Therefore, x = 3.

‎      ‏‏‎‎    

Answer:

Option B. One Solution

Step-by-step explanation:

5x+17= 4(3x-1)

5x+17 = 12x-4

17+4 = 12x-5x

21. = 7x

thus, x=3 (one solution)
