The possible outcomes of flipping 3 coins are:
HHH, HHT, HTT, TTT, HTH, THT, TTH, THH.
Out of these 8 there are 4 that will be successful so the probability is 4/8 = 1/2 or 50%.
50%
Answer and Explanation:
If you flip three fair coins, the probability that you'll get at least two heads is 4/8 or 0.50, which is 50%.

Sydney bikes 32 miles in 2 hours and 64 miles in 4 hours. He bikes at a constant rate. Which function gives the distance d that he travels in t hours?
A. d= 64 t
B. d= 32 t
C. d= 16 t
D. d = 8 t
Answer:
C. d = 16t
Step-by-step explanation:
Since she is biking at a constant rate, then you would just have to divide 32 by 2 to get 16, which would be the speed Sydney would ride in the matter of one hour. So for how many hours she bikes, multiplied by 16, would be the distance that she travels in said time.
Find the volume of the figure below. Round to the nearest tenth.
Answer:
The volume of the figure given is:
3057,57 cm^3Step-by-step explanation:
To find the volume of the figure in the picture, first, you must divide the figure in the two known figures there: a cylinder and a rectangular prism, now you can find the volume of each figure separated and at the last add the two volumes.
Volume of the cylinder.
The formula to find the volume of a cylinder is:
Volume of a cylinder = PI * r^2 * hWhere:
PI = 3,1416 approximately (In this case I´ll use the number without approximation, you can find this in the calculator).
r = radius (the distance from a side of the circle to the center of this, in this case, is 7 cm)
h = height (in this case is 7 cm too, you can find these values in the figure given)
Now we must replace the values:
Volume of a cylinder = PI * r^2 * h Volume of a cylinder = PI * (7 cm)^2 * 7 cm Volume of a cylinder = 1077,57 cm^3 approximately.Volume of the rectangular prism.
The volume of a rectangular prism is actually easy, you only must multiply the width, the length, and the height, so, the formula is:
Volume of a rectangular prism = width * length * height.When we replace the values given in the figure:
Volume of a rectangular prism = 11 cm * 20 cm * 9 cm Volume of a rectangular prism = 1980 cm^3At the last, we add the two volumes found:
Volume of the figure = 1077,57 cm^3 + 1980 cm^3 Volume of figure = 3057,57 cm^3I need help with this

What is the slope of the line represented by the equation y + 3 = -4(x - 5)?
Answer:
-4
Step-by-step explanation:
The point slope form of a line is
y-y1 = m(x-x1)
Where m is the slope and (x1,y1) is a point on the line
y + 3 = -4(x - 5)
The slope is -4

Find the area of the figure.
Answer:
First find the area of the rectangle.
length x width = area
160 x 20 = 3200 area of rectangle
150 - 20 = 130
160 - 110 = 50
length x width / 2 = area of triangle
130 x 50 = 6500 / 2 = 3250
3200+3250=6450 square meters

Vector performed an experiment at a local farm to determine if the addition of bananas to his biomass cow manure recipes helps produce more or less energy. He collected random samples of manure and bananas from the farm, prepared 15 bottles of each of both mixtures, and placed a balloon on top of each bottle. After two weeks he measured the circumference of each balloon in centimeters; the bigger the balloon grew, the more energy that was produced. The results of the experiment are displayed in the box plots below.
Which description most accurately summarizes the sample results?
Answer:
For his balloon to grow bigger, more manure is needed to enhance more growth energy
The mean of cow manure with mashed bananas is always more than the mean of only cow manure in any country.
Then the correct option is B.
What is Mean?Mean is simply defined as the average of the given set of numbers. The mean is considered as one of the measures of central tendencies in statistics. The mean is said to be an arithmetic mean. It is the ratio of the sum of the observation to the total number of observations.

The mean of cow manure will be
Mean = 10+11 +13 +13 + 14 +15 + 15 + 15 + 18 + 18 + 19 + 20 +22+25+26/15
= 254/15
= 16.93
The mean of cow manure with mashed banana will be
Mean = 22+22+26+29+30+31+36+36+38+39+43+46+46+49+50/15
= 543/15
= 36.2
Thus, The mean of cow manure with mashed bananas is more than the mean of only cow manure.

Answer:
Yes, because it passes the vertical line test
Step-by-step explanation:
A function has one output for each input. This is called a one to one correspondent. This is shown by the vertical line test
This graph passes the vertical line test and is therefore a function
Answer:
D
Step-by-step explanation:
The vertical line test is a visual way to determine if a curve is a graph of a function or not. A function can only have one output, y, for each unique input, x.
-------------------------------------------------------------------------------------------
Example: The first table is a function because each input value has only 1 output value, but the second table has more that one output value per input. (View Attached Picture Below)
The input value 4 in Table A has only 1 output value, 20. But in Table B, the input value for 4 has 2 output values, 16 and 17. So Table A is a function, while Table B is not.

A briefcase in the shape of a rectangular prism has a height of 10 cm and a volume of 4,875 Centimeters cubed. What is the area of the base of the briefcase?
243.75 centimeters squared
487.5 centimeters squared
2,437.5 centimeters squared
4,865 centimeters squared
Answer:
Step-by-step explanation:
the correct question is
A briefcase in the shape of a rectangular prism has a height of 10 cm and a volume of 4,875 cm³. What is the area of the base of the briefcase?
we know that
volume of a rectangular prism=area of the base*height
volume=4875 cm³
h=10 cm
area of the base=volume/height
area of the base=4875/10-----> 487.5 cm²
the answer is
the area of the base is 487.5 cm³
Answer:
487.5 cm³
Step-by-step explanation:
Use the distributive property to write the expression without parentheses. Then simplify the result, if possible.
1/3(6x+23)+1/3

Trina examined the equation below and said that the equation has exactly one solution. Negative 8 (x minus 4) + 2 x = negative 4 (x minus 8) minus 2 x Which explains whether Trina is correct? A. Trina is correct because the two sides of the equation are equivalent. B. Trina is correct because the two sides of the equation are not equivalent. C. Trina is not correct because the two sides of the equation are equivalent. D. Trina is not correct because the two sides of the equation are not equivalent.
Answer
The answer is C. Trina is not correct because the two sides of the equation are equivalent.
Step-by-step explanation:
1. solve for x
-8(x - 4) + 2x = -4(x - 8) -2x
-8x + 32 + 2x = -4x + 32 -2x
-6x + 32 = - 6x + 32
0 = 0
This equation has infinite solutions, any rational number fits as solution for x in this equation. And as we can see both sides of it are equivalent.
Therefore, the correct answer is C. Trina is not correct because the two sides of the equation are equivalent.
Hope This Helps :p

Solve this inequality.
-5x + 7 > 42
A. x> 245
B. x < -175
C. x > 7
D. x < -7
Answer:
x < -7
Step-by-step explanation:
-5x + 7 > 42
Subtract 7 from each side
-5x + 7-7 > 42-7
-5x > 35
Divide each side by -5, remembering to flip the inequality
-5x/-5 <35/-5
x < -7

Find the value of x. If necessary, round to the nearest tenth
Answer:
8
Step-by-step explanation:
→ Use trigonometry to find x, we have no hypotenuse so we utilise the TOA formula
TOA = Tan = Opposite ÷ Adjacent
→ The opposite of the triangle is 8√3 and we want to find the adjacent of this triangle so we rearrange
Opposite ÷ Tan
→ Substitute in the values
8√3 ÷ tan(60) = 8

height= 3 ft
Now,
Area=b*h
or, 12=b*3
or,b=12/3
b=4 ft.
The value of base is 4 ft.
