PLEASE HELP ASAP!!!!! a simulation by tossing a coin to model whether these puppies will be male or female. • Let heads (H) = female puppy • Let tails (T) = male puppy The results of the simulation are: 1. TTTT 6. HHHH 2. TTTT 7.HTHT 3. THTH 8. HHHH 4. HTTT 9. THTH 5. TTTT 10. HHHH What is the estimated probability that at least two of the puppies will be male?
Answer:
7/10 or 70%
Step-by-step explanation:
There has to be at least two T in each result of the simulation. This means you can also have 3 T's and 4 T's in the result.
These are the results that qualify as having at least two T's.
1. TTTT, 2. TTTT, 3. THTH, 4. HTTT, 5. TTTT, 7. HTHT, 9. THTH
That is 7 out of the 10 results which is 7/10 or 70%

Answer: 22x+2
Hope it helps!!!
solve the inequality
1/5x+3>9
Answer:
Step-by-step explanation:
First, you would want to subtract the 3 on the left side to the right side to get the 1/5x to be alone.
1/5x>6
Next, we need to solve for x, by multiplying 5 to cancel out the 1/5.
(5)1/5x>6(5)
That leaves us with x>30
treat the inequality sign as an equal sign, that should help

-You cant really see what 1 says but it says (The net below can be folded to make the triangular prism? Label the dimensions of the prism.)
And 8 says (Calculate the total area of the net and the surface area of the triangular prism from Problem 7. area net= surface area= ___ cm^2)
Answer:
1. Left side = 3 inches, Bottom side = 4 inches, Right side = 2 inches, Top side = 5 inches
2. A = 6 inches²
3. A = 8 inches²
4. A = 10 inches²
5. A = 12 inches²
6. A = 36 inches²
7. Left side = 5 cm, Bottom side = 12 cm, Right side = 4 cm, Top side = 13 cm
8. A = 180 cm²
Step-by-step explanation:
1. Label the dimensions of the prism:
Left side = 3 inches
Bottom side = 4 inches
Right side = 2 inches
Top side = 5 inches
2. Area of the red rectangle:
Formula:
LH = A (Length x Height = Area)
A = 3 x 2
A = 6 inches²
3. Area of the blue rectangle:
Formula:
LH = A (Length x Height = Area)
A = 4 x 2
A = 8 inches²
4. Area of the green rectangle:
Formula:
LH = A (Length x Height = Area)
A = 5 x 2
A = 10 inches²
5. (They gave the formula of the two triangles, but the question said green rectangle? They must've meant yellow triangles)
Area of the yellow triangles:
Formula:
2 (1/2 Bh) (2 (half of base x height))
A = 2(1/2 3 x 4)
A = 2(1/2 12)
A = 2(6)
A = 12 inches²
6. Total surface area of the triangular prism:
Formula:
LH + LH + LH + 2 (1/2 Bh) = Surface Area of the triangular prism (Area of the red rectangle + Area of the blue rectangle + Area of the green rectangle + Area of the yellow triangles = Total surface area of the triangular prism)
A = 6 inches² + 8 inches² + 10 inches² + 12 inches²
A = 36 inches²
7. Label the dimensions of the prism:
Left side = 5 cm
Bottom side = 12 cm
Right side = 4 cm
Top side = 13 cm
8. Total surface area of the triangular prism:
First, we can find the area of each shape, as we had previously to find the total area of the net and the surface area of the triangular prism.
Area of the red rectangle:
Formula:
LH = A (Length x Height = Area)
A = 5 x 4
A = 20 cm²
Area of the blue rectangle:
Formula:
LH = A (Length x Height = Area)
A = 12 x 4
A = 48 cm²
Area of the green rectangle:
Formula:
LH = A (Length x Height = Area)
A = 13 x 4
A = 52 cm²
Area of the yellow triangles:
Formula:
2 (1/2 Bh) (2 (half of base x height))
A = 2(1/2 5 x 12)
A = 2(1/2 60)
A = 2(30)
A = 60 cm²
Total surface area of the triangular prism:
LH + LH + LH + 2 (1/2 Bh) = Surface Area of the triangular prism (Area of the red rectangle + Area of the blue rectangle + Area of the green rectangle + Area of the yellow triangles = Total surface area of the triangular prism)
A = 20 cm² + 48 cm² + 52 cm² + 60 cm²
A = 180 cm²

Answer:
1372 cubic ft.
Step-by-step explanation:
[tex]V=\frac{4}{3} \pi 7^3[/tex]
[tex]V=\frac{4}{3} \pi 343[/tex]
[tex]V=457\frac{1}{3} \pi[/tex]
Since pi is 3 to find the approximate answer, do:
[tex]V=457\frac{1}{3} (3)[/tex]
[tex]V=1372[/tex]
Hence, the volume of the sphere is approximately 1372 cubic ft.
Answer:
V = 1,372 ft³
Step-by-step explanation:
You have been given the equation necessary for calculating the volume of a sphere:
[tex]V = \frac{4}{3} \pi r^{3}[/tex]
In this formula, "V" represents the volume, "π" is the given value (3), and "r" is the radius. While you have not been given the radius, you have been given the diameter (14 ft). The radius is half of the diameter.
radius = diameter / 2
radius = 14 ft / 2
radius = 7 ft
Now, you can plug this value into the formula and simplify to find the volume.
[tex]V = \frac{4}{3}\pi r^{3}[/tex] <----- Volume formula
[tex]V = \frac{4}{3} * (3) *r^{3}[/tex] <----- Plug 3 in for "π"
[tex]V = \frac{4}{3} * (3) * 7^{3}[/tex] <----- Plug 7 in for "r"
[tex]V = \frac{4}{3} * (3) * (343)[/tex] <----- Solve 7³
[tex]V = 1,372 ft^{3}[/tex] <----- Multiply all the terms together

Answer:
1. 660.52
2. 572.56
3. 283.53
4.254.47
5. 63.62
6. 380.13
Step-by-step explanation:
do πr²
r = radius
if you have a diameter like question 4 divide by 2 and you get radius
Answer:
1. A = 660.52 square units. C = 91.11 units.
2. A = 572.56 square units. C = 84.82 units.
3. A = 283.53 square units. C = 59.69 units.
4. A = 254.47 square units. C = 56.55 units.
5. A = 63.62 square units. C = 28.27 units.
6. A = 380.13 square units. C = 69.12 units.
Step-by-step explanation:
The equations for Area and Circumference of a circle are as follows:
A = πr², where r is the radius.C = 2πr, where r is the radius.You are given the radius (or diameter) of each circle which can be substituted into the above equations for r. Diameter is the entire length across the circle through the center, which is equal to 2(r).
1. A = π(14.5)² = 660.5198. The area is approx. 660.52 square units.
C = 2π(14.5) = 91.106. The circumference is approx. 91.11 units.
2. A = π(13.5)² = 572.555. The area is approx. 572.56 square units.
C = 2π(13.5) = 84.823. The circumference is approx. 84.82 units.
3. A = π(9.5)² = 283.528. The area is approx. 283.53 square units.
C = 2π(9.5) = 59.690. The circumference is approx. 59.69 units.
4. Diameter = 18; 18/2 = 9 = r. So, A = π(9)² = 254.469. The area is approx. 254.47 square units.
C = 2π(9) = 56.548. The circumference is approx. 56.55 units.
5. r = 9/2 = 4.5. So, A = π(4.5)² = 63.617. The area is approx. 63.62 square units.
C = 2π(4.5) = 28.274. The circumference is approx. 28.27 units.
6. A = π(11)² = 380.132. The area is approx. 380.13 square units.
C = 2π(11) = 69.115. The circumference is approx. 69.12 units.

Your Answer is... 4.5 or in exact form its, 9/2
Step-by-step explanation:
Convert the mixed numbers to improper fractions, then find the LCD and combine.
To find the least common denominator first convert all integers and mixed numbers (mixed fractions) into fractions. Then find the lowest common multiple (LCM) of the denominators. This number is same as the least common denominator (LCD).You can then write each term as an equivalent fraction with the same LCD denominator.Hopefully this helps you! ^^

"Find the surface area of each pyramid. Round to the nearest tenth if necessary."
Answer: The total surface area is 633.9
Step-by-step explanation:
12.25 times 15.75, then divide by 2 = 96.46875 (this is the area of the triangle
Then times 4 = 385.875 (Because there are four triangles
15.75 times 15.75 = 248.0625 (The area of the square)
The sum is 633.9375
Rounded = 633.9
Find the surface are of this figure
Answer:
If I am correct, I think the surface area is 448.
Step-by-step explanation:
First start by finding the area of all the sides
Front side. 12 x 10 = 120
2 triangle sides: 8 x 10 = 80, 80 x 2 = 160
Bottom side: 6 x 12 = 72
Back side: 8 x 12 = 96
Then add up the surface area
120 + 160 + 72 + 96 = 448
Btw I don't know if I am correct, but I think this is the way you find surface area.
A party hat has a height of 7 inches and a diameter of 6 inches. What is the volume of the party hat in cubic inches? Use 3.14 for pie.
Answer:
65.94 in³
Step-by-step explanation:
First, we need to determine to the shape, a party hat is a cone.
The volume formula that use to calculate the cone is 1/3hπr².
Notice: h is for height and r is for radius
Using this formula, we can easily set up the equation below:
1/3 · 7 · 3.14 · (6/2)² = 65.94 (cubic inches)
You must halved the diameter first (in this case, 6) and then square it.
So: The answer of this question is 65.94 in³
