Silvio created a table of the possible outcomes of spinning a spinner divided into 4 equal sections labeled A, B, C, and D and rolling a fair 6 sided number cube numbered 1-6. Using sample space, what's the probability of spinning the letter a and rolling a number less than 4?
Answer:
there is a 1/4 chance of getting a on the spinner and there is a 50% percent chance of getting less than 4 on the die.
Step-by-step explanation:
because there are 4 spaces and one answer is shown so yeah
Solve the system of equations - X - Y = 3 and 6x + 2y = -30 by
combining the equations
Answer:
X= -6, Y= 3
Step-by-step explanation:
1)
- X - Y = 3
- X - 3= Y
Y= - X - 3
2)
6X + 2Y = -30
3X + Y = -15
Y = -15 - 3X
3) Combine
- X- 3 = - 15 - 3X
- X = -15 - 3X +3
-X + 3X = - 12
2X = - 12
X= - 6
4)
- X-Y=3
-(-6) - Y = 3
-Y= 3-6
-Y= - 3
Y = 3
Answer: X= -6, Y= 3
{
6x + 2y = -30, 6(-6)+2(3)= -30

Betty measured the diagonal length of a playing card to be 15 inches. The short side of the card is 9 inches. What is the length of the long side of the playing card?
Answer:
L = 12 inches
Step-by-step explanation:
Using the Pythagorean theorem:
15² - 9² = L²
L² = 144
L = 12 inches

What is the slope of the line that passes through the points (5,−4) and (7, -4) ?Write your answer in simplest form.
Answer:
Undefined
Step-by-step explanation:
[tex]\boxed{slope = \frac{y1 - y2}{x1 - x2} }[/tex]
☆ (x₁, y₁) is the first coordinate and (x₂, y₂) is the second coordinate.
Slope of the line
[tex] =\frac{ - 4 - ( - 4)}{7 - 5} \\ =\frac{ - 4 + 4}{2} \\ = \frac{0}{2} \\ (undefined)[/tex]
Thus, the slope of the line is undefined.
(Since 2 cannot be divided by zero)
Notice that the two coordinates have the same y- coordinate of -4. This means that the line is a vertical line. Vertical lines have undefined slopes.
The distribution of time spent brushing teeth for the 1,200 students in a school is multimodal with a mean of 43 seconds and a standard deviation of 8.99 seconds. If a random sample of 9 students is selected, is it appropriate to calculate the probability of the sample mean being less than 30 seconds using an approximately Normal model? Yes, the population of 1,200 students is reasonably large in size, so the shape of the population is not a concern. Yes, the sample of 1,200 students is a reasonably large sample size, so the shape of the population is not a concern. No, it is not appropriate to estimate the probability using an approximately Normal model because the population is not Normal, and the sample size is small. No, it is not appropriate to estimate the probability using an approximately Normal model because the population is not Normal, but the sample size is reasonably large.

. Each tile is 3/2 feet by 3/2 feet. There are 10 tiles on the bathroom floor. What is the area covered by the tiles?
Answer:
22 and 1/2
Step-by-step explanation:
3/2 times 3/2 2 and 1/4
2 and 1/4 times 10 is
22 and 1/2
The required area covered by 10 tiles having dimensions 3/2 feet by 3/2 feet.
What is square?The square is a 4 sided figure, each side of the square is equal and make a right angle.
The area of square having sided a unit can be given by a² square unit.
Given that,
The length of tile = 3/2 feet,
And the width of tile = 3/2 feet.
Total number of tiles = 10.
The tiles are in square shape.
The area of one tile = 3/2 x 3 / 2 = 9 / 4 square feet
The area of 10 tiles = 9/4 x 10 = 22.5 square feet.
The area covered by 10 tiles is 22.5 square feet.

Find the probability that a randomly selected point within the circle falls in the white area
Answer:
Step-by-step explanation:
The white area is the area of the circle minus the area of the triangle.
Aw=pr^2-hb/2
Aw=p4^2-6.5(6)/2
Aw=16p-19.5
The probability of selecting the white area is the white area divided by the area of the circle
P(W)=(16p-19.5)/(16p), p=3.14
P(W)=0.61

$24 pizzas? (This is the delivery fee, tax and tip)
Answer:
32.94
Step-by-step explanation:
24(.22) [Both Sales tax and tip.] = $5.28 Add to the 27. You get $32.28
Or, you could be estimating based on the delivery fee too. Which the would be this:
27(.22) = 5.94 + 27 = 32.94

La finca de Federico tiene tiene un área de 576 m2, En ella ha sembrado naranja y café, 3/8 de la finca están sembrados de naranjas y el resto de café, ¿Cuál es el área de la finca que están sembrada por café?
Answer:
El área de la finca que está sembrada por café es 360 m².
Step-by-step explanation:
La finca de Federico tiene tiene un área de 576 m². [tex]\frac{3}{8}[/tex] de la finca están sembrados de naranjas. Entonces, el área de la finca que está sembrada por naranjas se calcula mediante:
576 m²* [tex]\frac{3}{8}[/tex] = 216 m²
Sabiendo que el resto de la finca esta sembrada de café, esta área se calcula mediante la diferencia del área total de la finca y el área sembrada por naranjas:
576 m² - 216 m²= 360 m²
El área de la finca que está sembrada por café es 360 m².
Consecutive integers are integers that
differ by one. You can represent
consecutive integers as x, X + 1,
x + 2 and so on. Write an equation
and solve to find three consecutive
integers whose sum is 33.
Answer: The three numbers are 10, 11, and 12.
10+11+12 = 33
=========================================================
Work Shown:
x = smallest numberx+1 = middle numberx+2 = largest numberEach is a positive whole number
Add them up and set the result equal to 33. Solve for x.
(x) + (x+1) + (x+2) = 33
3x+3 = 33
3x+3-3 = 33-3 .... subtract 3 from both sides
3x = 30
3x/3 = 30/3 ..... divide both sides by 3
x = 10
x+1 = 10+1 = 11
x+2 = 10+2 = 12
Note how 10+11+12 = 33 to help confirm our answer.

Answer:
Answer 1. 3in
Answer 2. 0.875in
Answer 3. 26 miles
Answer 4. 7.67in
Step-by-step explanation:
Answer 1. We know that 2 feet in real life is going to equal 1 inch, so since the person is 6 feet, we divide that by 2 to get 3. So the action figure is going to be 3in.
Answer 2. In this case, we see that 1 foot is equal to four inches. That must mean that 1 inch is equal to a quarter foot. So we just multiply
0.25 x 3.5 = 0.875
The length is 0.875 feet
Answer 3.
We know that 1 inch = 6.5 miles, and there are 4 inches on the map, so we have to multiply 6.5 x 4 to find out how many miles there is.
Answer 4.
To find this one out, we have to divide 9 into 69. That gives us 7.67. So 69 nautical miles would be equal to 7.67 inches on the map
