Some students recorded how many minutes they spent on the phone in one day. They put the results in a Stem-and-Leaf Plot.

What is the mean number of minutes spent on the phone?

Answers

Answer: 31

Explanation:

The data from the stem-and-leaf plot is:

10,

24,25,26,

30,30,32,33,

40,45,46

Add up those values

10+24+25+26+30+30+32+33+40+45+46 = 341

Then divide over n = 11 which is the sample size.

341/11 = 31 is the arithmetic mean.

Answer:

341/11 = 31 is the arithmetic mean.

What is the height of a cylinder with a radius of 3 and a volume of 189?

Answers

Answer:

6.68 units (2 d.p.)

Step-by-step explanation:

The formula for the volume of a cylinder is:

$\boxed{V=\pi r^2 h}$

where:

V is the volume.r is the radius of the circular base.h is the height.

Given values:

V = 189 cubic unitsr = 3 units

To find the height of the cylinder, substitute the given values into the formula and solve for h:

$\implies 189=\pi \cdot 3^2 \cdot h$

$\implies 189=9\pi \cdot h$

$\implies \dfrac{189}{9 \pi}=\dfrac{9\pi \cdot h}{9 \pi}$

$\implies \dfrac{189}{9 \pi}=h$

$\implies h=6.6845076...$

Therefore, the height of a cylinder with a radius of 3 units and a volume of 189 cubic units is 6.68 units (2 d.p.).

Answer:

h≈6.68

Step-by-step explanation:

6.68 is the height of a cylinder with a radius of 3 and a volume of 189

Hello Love! Sense this is a Suplementary angle you must know it will add up to equal 180 so we already have 1 angle that is 95 degrees so we will subtract that and get 85 so we must know that 5 multiplied by x will equal 85 so I do 85 divided by 5 and get 17 I check my work and do 17 x 5 and that gets you 85 so 17 is our answer

two lines meet at a point that is also the vertex of an angle. Set up and solve an equation to find the value of m.

Answers

Answer:The vale of m is

Step-by-step explanation:

First, we have to find the angle between 24° and 68° and let that angle be- x°

As the right angle,

90° = 68°+ x°

22° = x°

Now,

Angle m = angle x° + 24° ( vertical opposite angles)

m = 22 +24

m = 46

Answers

Answer:

Mean = 33.7

Median = 34.5

Mode = 34

Range = 33

After adding 26....

mean decreases by 0.7

median decreases by 0.5

mode is 34

range is 33

Step-by-step explanation:

mean = sum of all the data values/number of data values

= (18 + 19 + 20 + 34 + 34 + 35 + 37 + 42 + 47 + 51)/10
= 337/10
= 33.7

To find median arrange the values in increasing order, find the mid value

If the number of data points is even, find the average of the mid 2 data values

Arranging data values we get:
18, 19, 20, 34, 34, 35, 37, 42, 47, 51

Since there are 10 data values, take the average of the middle two:
(34 + 35)/2 = 34.5

The mode is the value that occurs most often. We see that there are two instances of 34 whereas the other values appear only once

Mode = 34

The range is highest - lowest = 51 - 18 = 33

After we add 26, we get the following data set arranged

18, 19, 20, 26, 34, 34, 35, 37, 42, 47, 51

we can calculate the stats using the same technique as above

We get the following values

mean = )(18 + 19 + 20 + 26 + 34 + 34 + 35 + 37 + 42 + 47 + 51)/11
= 33

median = 34

mode = 34

range = 51-18 = 33

To find the decrease in mean and median subtract from the first set of values

im pretty sure the answer is 56 because i said so

Banana Cupcakes
makes 10 cupcakes

cup vegetable oil

1 large egg

4 tablespoons sour cream

2 medium-sized ripe bananas, mashed

1 cups all-purpose flour

1 teaspoon baking soda

teaspoon salt

1 teaspoon vanilla extract

pinch of nutmeg

You will use the recipe above to answer the following questions:

This recipe serves 10, but you need to serve 30. What number will you need to multiply the amount of each ingredient by to adjust the recipe? How did you determine this number?
How much vegetable oil do you need for 30 cupcakes?
How much flour do you need for 30 cupcakes?
What is the difference in the amount of vanilla extract you would need for 30 cupcakes?
What is the difference in the amount of salt you would need for 30 cupcakes?
In the real world, even though you make adjustments to a recipe to accommodate the number of people you need to serve, you sometimes round the amount of an ingredient instead of using an exact amount. Which ingredient would it make more sense to round rather than coming up with the exact amount? Why?

Answers

Answer: Hey give me 1 hour and ill answer it I'm doing odessyware rn so Ill get back to you later appreciate yo patients.

Step-by-step explanation:

Here we have a recipe that works for 10 serves.
Then, if we want to make 30 servings, we need to use that recipe 3 times. (because x*10 = 30, then x = 30/10 = 3)
This would be equivalent to multiply each ingredient by 3.
for 30 cupcakes we need:
3 cups of vegetable oil.
3 cups of all-purpose flour
(because for each one of these ingredients we needed only 1 cup to make 10 cupcakes).
for 10 cupcakes we need 1 teaspoon of vanilla.
for 30 cupcakes we need 3 teaspoons of vanilla, the difference is 3 - 1 = 2.
So the difference is 2 teaspoons.
About which quantities we should round are those where we may have mixed numbers or big numbers.
For example, we have 4 tablespoons of sour cream for 10 servings, then for 30 servings we should have:
3*4 = 12 tablespoons.
We could round this down to 10 tablespoons.

Step-by-step explanation:

Error Analysis: A store is instructed by corporate headquarters to put a markup of 67% on all items. An item costing $6 is displayed by the store manager at a selling price of $4. As an employee, you notice that this selling price is incorrect. Find the correct selling price. What was the manager's likely error?

Part 1: The correct selling price is (Round to the nearest dollar as needed.)
Part 2: What was the manager's likely error?

A. The manager set the selling price at the markup.
B. The manager subtracted the markup from the cost instead of adding it.
C. The manager set the selling price at the cost.
D. The manager added the markup to the cost instead of subtracting it.

Answers

Answer:

To find the correct selling price, we need to first find the cost of the item plus the markup. We can do this by multiplying the cost of the item by the markup percentage: $6 * 67% = $4.02. However, since the question asks us to round to the nearest dollar, we can round this number down to $4.

Therefore, the correct selling price is $4.

The manager's likely error was that they set the selling price at the cost (option C).

Step-by-step explanation:

The correct selling price is $10 and the manager set the selling price at the markup so option (A) is correct.

What is the percentage?

The percentage is defined as a given amount in every hundred. It is a fraction with 100 as the denominator percentage is represented by the one symbol %.

The percentage is also called the indicating hundredths. Thus, 2% is two-hundredth, which means 2%=2/100=0.02.

As per the given,

Cost of item = $6

Markup = 67%

67% of $6 ⇒ 0.67 x 6 = $4.02

Add the markup in the cost = $6 + $4.02 = $10.02

Round to nearest dollars = $10.2 ≈ $10.

The manager put $4 which is a markup instant of the selling price of $10.

Hence "The correct selling price is $10 and the manager set the selling price at the markup".

0.5% of w = 12. Only the first answer has the equation equal to 12, so the first part is

$12 = 0.005 \times w$

Now to solve it, we want to get W alone, we can do that by dividing 0.005 on both sides. Since right now it's being multiplied we must do the opposite

$w = \frac{12}{0.005} = 2400$
