that this event occurs. The probability that Calvin caught a red sheet is
. It is
that this event occurs.
Reset
Answer:Calvin throws 12 sheets of paper up in the air.
He randomly catches one of the sheets as they float down.
Of the 12 sheets of paper, 9 are white and 3 are red.
Probability = Number of favorable outcomes/ total number of outcomes
The probability that Calvin caught a white sheet is = or 75%.
It is likely that this event occurs as above 70% we say that the event is likely and here the probability is 75%.
The probability that Calvin caught a red sheet is = or 25%
This is unlikely to happen. Thus, we can say that it is not likely event.

Identify the equation of direct variation given that y varies directly with x.
y is 15 when x is 11.
The equation of direct variation given that y varies directly with x.
y is 15 when x is 11 will be [tex]y = \dfrac{15}{11} x[/tex].
What is proportionality?The proportional relationship between x and y can be written symbolically as
[tex]x \propto y[/tex]
That middle sign is called the sign of proportionality.
Variation: Direct from y to x:
[tex]x \propto y[/tex]
y = 15, x= 11
Write the equation
[tex]x \propto y[/tex]
Express as an equation
[tex]y = kx[/tex]
Where k is the constant of variation
Substitute
y = kx
15 = 11k
Solve for k
k = 15/11
Substitute in [tex]y = kx[/tex]
[tex]y = \dfrac{15}{11} x[/tex]
Thus, the equation of direct variation given that y varies directly with x.
y is 15 when x is 11 will be [tex]y = \dfrac{15}{11} x[/tex].

How do I find the vertex function
Answer:
oh ok. So, first, you get the equation in the form y=ax2+bx+c. Next, you calculate -b / 2a. This is the x-coordinate of the vertex. Then finally, you plug in the value of -b / 2a into the equation into the x variable and solve for the y variable. This is the coordinate of the vertex.

In triangle PQR,PQ=13 cm ,QR=18 cm and PR = 11 cm. Find the size of the largest angle.
Answer: ~96.83°
Step-by-step explanation:
1) It's obvious that the largest angle is the opposite to the largest side.
▪︎ QR = 18 (the largest side)
=> <QPR is the largest angle
2) Cosine Rule:
▪︎ QR^2 = QP^2 + PR^2 - 2*QP*PR*cos(QPR)
▪︎ 18*18 = 13*13 + 11*11 - 2*13*11*cos(QPR)
▪︎ 324 = 169 + 121 - 286*cos(QPR)
▪︎ 34 = -286*cos(QPR)
▪︎ cos(QPR) = -34/286
▪︎ <QPR = arccos(-34/286) = 96.827...°

Lateral Surface Area :
Area of the side faces (exclude the base)4 x 1/2 x 8 x 32 x 2448 units²Answer:
48 units²
Step-by-step explanation:
The lateral area of a square based pyramid comprises the four triangular sides.
Area of a triangle = 1/2 × base × height
= 1/2 × 8 × 3

∠ABC = 39°
Step-by-step explanation:
Since ED bisects ∠CBD :
∠EBD = ∠CBE = 30°
Now, ∠ABD = ∠ABC + ∠CBE + ∠EBD = 99°
Solving :
99° = ∠ABC + 30° + 30°∠ABC = 99° - 60°∠ABC = 39°It costs $363 to make 90 bags of cotton candy and $440 to make 200 bags of cotton candy.

A trash can is shaped like a right rectangular prism. It has a base area of 3 square feet and a height of 314 feet.
What is the volume of the trash can?
4 7/8 ft³
6 1/4ft³
9 3/4ft³
12 1/2 ft³
Answer:
I think you may have made a typo, as it is extremely unlikely that a trashcan is 314 feet tall. I will assume that you meant 3.14 feet.
Step-by-step explanation:
We already have the base, so we can already cut out one step. If we were not given the base, however, we would simply multiply the length by the width of the prism. Next we multiply the base by the height (3 X 3.14) to get the volume of the prism, 9.42 cubic feet. In the case that there was no typo, and 314 was the correct height, the volume would be 942 cubic feet.

Step-by-step explanation:
Using the area of a sector formula, we get the area of the entire sector is [tex](\pi)(27.8^{2})\left(\frac{150}{360} \right)[/tex].
Using the formula [tex]A=\frac{1}{2} ab \sin C[/tex], we get the area of the triangle is [tex]\frac{1}{2}(27.8)(27.8)(\sin 150^{\circ})[/tex].
So, the area of the shaded sector is [tex](\pi)(27.8^{2})\left(\frac{150}{360} \right)-\frac{1}{2}(27.8)(27.8)(\sin 150^{\circ}) \approx \boxed{818.4}[/tex]

What is surface area?The surface area of a solid object is a measure of the total area that the surface of the object occupies.
Given that, a basketball has a diameter of 9 inches we need to find its surface area,
Since, the basketball is in the shape of the sphere and the surface area of the sphere = 4π×radius²
Therefore, the surface area of the basketball =
= 4×3.14×(9/2)²
= 4×3.14×4.5×4.5
= 254.34 in²
Hence the surface area of the basketball with diameter of 9 in will be 254.34 in².

The sum of negative eighteen and a number is eleven. What is the number?
Which equation could be used to solve the problem?
Answer:
-18 + x = 11
x = 29
Step-by-step explanation:
To solve this, you can use the formula of a + b = c
[tex]-18 + x = 11\\-18 = 18\\11 + 18 = 29\\x = 29[/tex]
Answer:
29
Step-by-step explanation:
Your equation can be -18+x=11. Since we don't know the number, we can use x. We are trying to find out a number that when it's added to -18, the answer will be 11.
Now, we solve the equation:
-18+x=11
x=11+18
x=29. Answer
To check this answer:
we can use our equation and substitute 29 for x.
-18+x=11
-18+(29)=11
11=11.
They are equal. Therfore, the answer is correct.

Answer:
y=-x+6
Step-by-step explanation:
Start by graphing y=-x+5. Then mark the point (2,4) for easier reference. A parallel line just has the same slope, so if you make another line with the same slope, and change the y-intercept until the line goes through (2,4), you will have the answer.
