The coin is flipped one more time. A tree diagram has been started for you to represent the possible outcomes. Determine the results from another coin flip. What is the probability that the coin lands heads up all three times?

Answer:

1) A profit of Rs 250 is made.

3) 11 marks

3) 14/15 kg

4) 15/28

Step-by-step explanation:

1) A profit of Rs.10 per bag of oranges and a loss of Rs.5 per bag of grapes sold. The total profit/loss from selling 200 bags of oranges and 350 bags of grapes is:

total profit/loss = 200 (10) - 5(350) = 2000 - 1750 = Rs 250

A profit of Rs 250 is made.

2) (+5) marks are given for every correct answer and (-3) marks are given for every incorrect answer and 0 for answer not attempted. If he answer 4 correct and 3 incorrect out of 7 questions. His score is:

Score = 5(4) - 3(3) = 20 - 9 = 11 marks

His score is 11 marks

3) An object weighs 28/5 kg on earth. Since its weight on moon is  1/6 its weight on Earth.

The weight on moon = 1/6 × 28/5 = 14/15 kg

4) 3/4 of 5/7 = 15/28

Answer:

Mean = 11.8

Median = 11

Step-by-step explanation:

Here we are asked to calculate the median and the mean for these set of numbers

Let’s start with the mean

The mean refers to the average, we simply add all the numbers together and divide by their count.

That would be;

Arithmetic mean = (10+ 5 + 18 + 9 + 17 + 12)/6 = 71/6 = 11.833 which is 11.8 to the nearest tenth

To get the median, what we do is to first rearrange the values we have from the lower to the highest.

That would be;

5,9,10,12,,17,18

Looking at the numbers after rearranging, the two middle numbers we have are 10 and 12.

So we add these together divide by 2.

That would be (10+12)/2 = 22/2 = 11

Answer:

P(multiples of 12)=1/25

Step-by-step explanation:

Multiples of 12: 12, 24, 36, 48

That is 4/50=1/25

Answer:

- number of hours on video games and test scores

- average running speed and total race time

- outside temperature and amount of a heating bill

Step-by-step explanation:

1. number of hours on video games and test scores (negative correlation - as you spend more hours on video games, test scores might decrease)

2. speed of a car and minimum stopping distance (positive correlation - as the distance to the next stop increases, the speed of the car should increase)

3. average running speed and total race time (negative correlation - as you run for longer, your speed should decrease)

4. adult’s head circumference and age (positive correlation - as your age increases, your head size increases, too)

5. outside temperature and amount of a heating bill (negative correlation - as temperature increases, the heating bill decreases)

The two options with negative correlations are:

"Number of hours on video games and test scores" and "Outside temperature and amount of a heating bill"

A relation between two variables, x and y, has a negative correlation when if one variable increases, the other decreases.

From the options, the ones that can have a negative correlation are:

Number of hours on video games and test scores: Here as the number of hours that you play video games increases, it is possible that your test scores decrease, so we have a negative correlation.

Outside temperature and amount of a heating bill: As the outside temperature decreases, the amount that you pay in heating increases, so again, we have a negative correlation.

The volume of the pyramid is 165.4 inches^3

Step-by-step explanation:

In this question, we are asked to calculate the volume of the pyramid with a square base and also with the given height.

To find the area of this pyramid, what we need to do is to multiply the area of the base by the height of the pyramid

From the question, the area of the square base is 11.9 in^2 while the height of the pyramid is 13.9 in

Thus the volume here is simply 11.9 * 13.9 = 165.41 which to the nearest tenth of cubic inch is 165.4 inch^3

Answer:

y=-6

Step-by-step explanation:

The line shown is a horizontal line through the y-axis and has the equation y=4. A parallel line to it is a line that does not cross it. It will also have the form y=a where a is the y-coordinate of its points. The point (-4,-6) is on the line so y=-6 is the line.

130 / 10 = 13

13 x 3 = 39

130 - 39 = 91

Answer:

91 students passed the test.

Step-by-step explanation:

We need to find 10% of 130.

130÷10=13

Then we need to make it 30% in order to see the amount of students that failed the test.

13×3=39

Then we need to do 130 - 39 (The whole class- 30%)

130-39=91

Answer:

12 toppings

Step-by-step explanation:

To do this, we need to write an equation for each place, and then, equal both equations to solve for this.

Let's call "y" the price of the pizza, and "x" the number of toppings.

At Vincents, pizza costs 6.75 + 0.75 for each topping, so the equation here would be:

y = 6.75 + 0.75x  (1)

Now, at italian pizza, a pizza costs 6.15 + 0.80 per topping, so the equation:

y = 6.15 + 0.80x  (2)

Now, we don't need to know the actual price of the pizza, we only want to know how many toppings we need to add on both places, so the pizza has the same price. We have both equations, it's time to equal both of them:

Equalling (1) and (2) we have:

6.75 + 0.75x = 6.15 + 0.80x

Now, let's solve for x:

6.75 - 6.15 = 0.80x - 0.75x

0.6 = 0.05x

x = 0.6 / 0.05

x = 12

So the number of toppings to include in the pizza so the price is the same for both places, will have to be 12 toppings.

Answer:

12 toppings and the prize will be the same.

Step-by-step explanation:

Let

number of toppings = a

Medium pizza at Vincent's

cost  = 6.75 + 0.75a

Medium pizza at Original Italian Pizza

cost  = 6.15 + 0.80a

For the cost to be the same

6.75 + 0.75a = 6.15 + 0.80a

collect like terms

6.75 - 6.15 = 0.80a - 0.75a

0.6  = 0.05a

divide both sides by 0.05

a = 0.6/0.05

a = 12  

12 toppings and the prize will be the same.

A circle is a two-dimensional figure. It is the locus of all points equidistant from a central point.

For a circular cross-section of a sphere that does not pass through the center,

the radius will be smaller than the radius of the sphere, the volume of the 2 pieces of the sphere will not be the same

x = 12

Step-by-step explanation:

Hi, to answer this we have to equal both equations given and solve for x.

2/3x+2 = 4/3x-6

Solving for x:

2/3x-4/3x= -6-2

-2/3x = -8

x = -8/ (-2/3)

In conclusion, when the value of x is equal to 12, both expressions will have the same value.

Step-by-step

n=smallest integer; n+1=second integer; n+2=third integer; n+3=fourth integer

n+(n+1)+(n+2)+(n+3)=34

4n+6=34

4n=28

n=7 ANSWER: The smallest integer is 7

CHECK:

7+8+9+10=34

34=34

the least of the four consecutive integers is 7.

Let's denote the four consecutive integers as x, x + 1, x + 2, and x + 3.

According to the given information, the sum of these four consecutive integers is 34:

x + ( x + 1 ) + ( x + 2 ) + ( x + 3 ) = 34

Simplifying the equation:

4 x + 6 = 34

Subtracting 6 from both sides:

4 x = 28

Dividing both sides by 4:

x = 7

The four numbers are 7, 8, 9, 10

Therefore, the least of the four consecutive integers is 7.
