If 25 people play the game how many people do you expect to hit HHH?
Answer:
Almost 3 persons are expected to hit HHH.Step-by-step explanation:
To find the answer we must use the diagram, we see that among 8 possible results, there's one possible outcome to hit HHH.
So, to find the amount of people that are expected to hit HHH, we just have to multiply each percentage assigned to the HHH outcome:
[tex](0.7)(0.5)(0.3)=0.105[/tex]
Now, we see that a 10.5% of the people will be expected to hit HHH.
The approximate number of people would be:
[tex]25(0.105) \approx 3[/tex]
Therefore, almost 3 persons are expected to hit HHH.
If kaitlyn goes to the store, the probability that she buys blueberries is 90%. the probability of her going to the store is 30%. what is the probability of her going to the store and buying blueberries?
Final answer:
The answer explains the calculation of the probability of an event occurring using provided probabilities and the intersection formula.
Explanation:
The probability of Kaitlyn going to the store and buying blueberries can be calculated using the formula for the intersection of two events.
We know that P(going to the store) = 0.3, P(buying blueberries) = 0.9, and we are looking for P(going to the store and buying blueberries).
Therefore, the probability of Kaitlyn going to the store and buying blueberries is 0.3 × 0.9 = 0.27 or 27%.

Find the value of x and y
Answer:
B. [tex]x=62[/tex]; [tex]y=30[/tex]
Step-by-step explanation:
We have been given two similar triangles. We are asked to find the value of x and y for the given triangles.
[tex]\Delta SWK\sim \Delta EBT[/tex]
We know that the measure of corresponding angles of two similar triangles are equal.
[tex]m\angle S=m\angle E[/tex]
[tex]m\angle W=m\angle B[/tex]
[tex]m\angle K=m\angle T[/tex]
[tex]110=2x-14[/tex]
[tex]2x-14=110[/tex]
[tex]2x-14+14=110+14[/tex]
[tex]2x=124[/tex]
[tex]\frac{2x}{2}=\frac{124}{2}[/tex]
[tex]x=62[/tex]
[tex]m\angle S=m\angle E[/tex]
[tex]40=m\angle E[/tex]
Using angle sum property, we will get:
[tex]m\angle E+m\angle B+m\angle T=180[/tex]
[tex]40+y+110=180[/tex]
[tex]y+150=180[/tex]
[tex]y+150-150=180-150[/tex]

A wedsite charges a fixed amount for each song download.If you can download six songs for $4.68,then how much would it cost to download ten song?
By determining the cost per song, which is $0.78, we can calculate that downloading ten songs from the website would cost $7.80.
Explanation:To determine the cost to download ten songs, we first need to calculate the cost per song. We are given that six song downloads cost $4.68. By dividing this total cost by the number of songs, we find the cost per song:
Cost per song = Total cost for six songs / Number of songs
= $4.68 / 6
= $0.78 per song
Now, to find the cost of ten songs, we multiply the cost per song by ten:
Total cost for ten songs = Cost per song * Number of songs
= $0.78 * 10
= $7.80
Therefore, it would cost $7.80 to download ten songs from the website.
The circle is inscribed in the triangle. Find the perimeter of the triangle.
A. 20 cm
B. 24 cm
C. 35 cm
D. 48 cm
The perimeter of the triangle will be 48 cm. The correct option is D.
What is a perimeter?A perimeter is the total length of the boundary or outer edge of a two-dimensional shape. It is the sum of the lengths of all the sides of the shape.
For example, the perimeter of a rectangle is the sum of the lengths of all four sides, while the perimeter of a circle is the distance around its circumference. The perimeter is usually measured in units such as meters, centimeters, inches, or feet, depending on the context of the problem.
Whenever we have two tangents outside the circle and they are in contact with each other, it means their lengths are the same
The perimeter of the triangle will be calculated as,
Perimeter = sum of all the sides
Perimeter = ( 11 + 11 + 7 + 7 + 6 + 6 )
Perimeter = 48 cm

You want to draft a four player tennis team. There are eight players to choose from. How many different teams can you form?
We want to make a 4 players team, and there are total 8 players. As we know the order of selection does not matter in a team of players, only the combination of players matters.
So we would use concept of Combinations and It will be choose 4 out of 8 players.
The formula for Combination is given as follows :-
[tex]nCr = \frac{n!}{r!*(n-r)!} \\\\ Choose \;4 \;out \;of \;8 \;players \\\\ 8C4 = \frac{8!}{4!*(8-4)!} = \frac{8!}{4!*4!} \\\\ 8C4 = \frac{8*7*6*5*4*3*2*1}{(4*3*2*1)*(4*3*2*1)} = \frac{8*7*6*5}{4*3*2*1} =\frac{1,680}{24} = 70 \;combinations[/tex]
Hence, Total number of different teams = 70 combinations.

What is the surface area of a cone with diameter 28 cm and height 22 cm in terms of pi?
a. 196 pi cm^2
b.365 pi cm^2
c.561.1 pi cm^2
d.2202.8 pi cm^2
The surface area of a cone with diameter 28 cm and height 22 cm in terms of pi is:
c. 561.1 pi cm²
Step-by-step explanation:The diameter of cone= 28 cm
Radius of cone is half the diameter this means that:
Radius(r) of cone= 14 cm
Also, height(h) of cone= 22 cm
We know that the surface area of cone is given by:
[tex]Surface\ Area=\pi r(r+\sqrt{h^2+r^2})[/tex]
Now as we know the value of h and r hence we will substitute these values in the formula to get:
[tex]Surface\ Area=\pi \times 14(14+\sqrt{(14)^2+(22)^2})\\\\\\Surface\ Area=14\pi (14+26.07681)\\\\\\surface\ Area=14\pi\times 40.07681\\\\\\Surface\ Area=561.07534\pi cm^2[/tex]
Hence, the surface area of cone is: 561.1π cm²

How to find amplitude and period from equation?
Final answer:
The amplitude of a wave is the coefficient A in the equation y(x, t) = A sin(kx - ωt + φ), and the period T can be calculated using T = 2π/ω, where ω is the angular frequency. Additional properties like wavelength and speed can be found using related equations involving the wave number and frequency.
Explanation:
To find the amplitude and period from the equation of a wave, look at the standard form of a sinusoidal wave function, which is generally y(x, t) = A sin(kx - ωt + φ). Here, the amplitude can be directly read from the equation as the coefficient A, which represents the maximum displacement from the rest position. As for the period, it can be derived from the angular frequency using the formula T = 2π/ω, where T is the period and ω is the angular frequency.
The wavelength (λ) and speed (v) of the wave can also be determined from the properties of the wave. The wavelength is related to the wave number by the equation λ = 2π/k, and the speed can be calculated if the frequency (f) is known, using the equation v = λf.
For example, if the amplitude is provided as 30 V/m and the frequency is given as 2.0 MHz, the period (T) would then be 5.0 × 10-7 s based on the relationship between frequency and period, T = 1/f.

You and a friend go to a mexican restaurant. you order 2 tacos and 3 enchiladas and your friend orders 3 tacos and 5 enchiladas. one bill was $7.80 plus tax and the other bill was $12.70 plus tax. how much was each taco and each enchilada?
To find the cost of each taco and enchilada, set up a system of equations based on the given bills and solve for the variables T (taco) and E (enchilada). The solution reveals that each taco costs $0.90 and each enchilada costs $2.00.
To solve the problem of determining the individual cost of a taco and an enchilada based on the two given bills, we can set up a system of linear equations. Let's denote the price of a taco as 'T' and the price of an enchilada as 'E'.
The first equation represents your order: 2T + 3E = $7.80.
The second equation represents your friend's order: 3T + 5E = $12.70.
To solve the system, you can use either the substitution or elimination method. For this example, we'll use the elimination method:
Multiply the first equation by 3 and the second by 2, which gives us:So, each taco cost $0.90 and each enchilada cost $2.00.
