Based on the experiment, what is the probability of landing on heads? Ty flipped a coin and counted how many times it landed on heads and how many times it landed on tails. The frequencies are shown in the following table. Result Number of Times Flipped Heads 26 Tails 30 Based on the experiment, what is the probability of landing on heads? Enter your answer as a fraction, like this: 42/53ur answer as a fraction, like this: 42/53
Answer:
the possibility of it landing on heads is 50/50
there is a 50% chance of it landing on heads and there is a 50% chance of it landing on tails
Step-by-step explanation:
however, there is also more of a possibility of it landing on tails because of the fact that Ty flipped the coin and it landed on tails more than heads
so I'd say abt 85/100 are the possibilities of it landing on heads

In which number does the digit 3 have a value that is ten times greater than the value of the digit 3 in the number 145,317
Answer:
Step-by-step explanation:
The value of the digit "3" in "156.32" is 3/10 (3 tenths). 10 times that value would be 3 (3/10 * 10 = 3). So now we need a number that has the digit "3" in it and the value of that digit is "3".
How about 143.26? The digit "3" is in the ones place and so its value is 3*1 or 3. The rest of the number is just made up, nothing special about any of the other numbers.
The value of digit 3 in 156.32 is 3/10 (3 tenths).
10 times that value would be 3 (3/10 * 10 = 3).
What is the value of digits?The face value of a digit is the magnitude that it possesses naturally. It is independent of the digit's position in the number.
The place value of a digit depends on its position in the number.
So now we need a number that has the digit 3 in it and the value of that digit is 3.
How about 143.26. The digit 3 is in the one place and so its value is 3*1 or 3.
The rest of the number is just made up, nothing special about any of the other numbers.

Answer:
X=12
Step-by-step explanation:
Add the two equations together and equate them to 180 due to the geometrical reason that angles on a straight line add up to 180.
10X-20+6X+8=180 (collect like terms)
10X+6X=180-8+20

22.40 tourists are coming from Switzerland to visit Mt Everest. They planned to stay at Everest base camp for 4 days. For this purpose they ordered some squared base pyramid tent in Nepal. A tent can holds people and each person have o fitx3ft space on the ground withi 48 cu. of air to breadth. Find the total cost of all tents at the rate of Rs.560 per feet square
The cost of 32.57ft^2 is Rs. 18,239.2 which is the cost of renting one tent.
Data;
Height = 48cu = 48 cubic feet = 3.63 feetedge length = 3ftarea = ?Area of a Square PyramidThe formula of a square pyramid is given as
[tex]A = l^2 + 2l\sqrt{\frac{l^2}{4} + h^2} \\[/tex]
Let's substitute the values and solve for the area of the square pyramid.
[tex]A = l^2 + 2l\sqrt{\frac{l^2}{4} + h^2} \\\\A = 3^2 + 2*3\sqrt{\frac{3^2}{4} + 3.63^2} \\A = 9 + 6{\sqrt{15.43} } \\A = 32.57ft^2[/tex]
Since the cost of 1 square foot = Rs. 560
32.57 ft^2 = x
[tex]1sq = 560\\32.57 = x\\x = 32.57 * 560\\x = 18,239.2[/tex]
The cost of 32.57ft^2 is Rs. 18,239.2 which is the cost of renting one tent.

Find the equation of the line that is parallel to the line y = 2x – 2 and passes through the point (5, -1). Write the equation in point- slope form.
Solution:
We know that:
Equation of parallel line: y = 2x - 2Since the parallel line has a slope of 2, the equation of the original line will also have a slope of 2. Now, let's use point-slope form to find the equation.
y - y₁ = m(x - x₁)y - (-1) = 2(x - 5)y + 1 = 2(x - 5)Thus, the equation of the line in point slope form is y + 1 = 2(x - 5).

Find the value of x if the perimeter is 30. X+3, x, 2x-1
Step-by-step explanation:
Perimeter represents the sum of all of the sides adding.
The problem is stating that;
[tex]30 = x + x + 3 + 2x - 1[/tex]
Combine like terms;
[tex]30 = 4x + 2[/tex]
Subtract from both sides;

Divide each side by 4;
[tex]7= x[/tex]
Check;
[tex]30 = 7 + 7 + 3 + 2(7) - 1[/tex]
[tex]30 = 17 + 14 - 1[/tex]

She also orders a photo album for $8. 69. Vera pays taxes that are 7% of the total purchase price. Her shipping charges are based on the following table: Amount of Purchase Standard Shipping Express Shipping up to $20 free $3. 50 $50 up to $100 $6. 35 $8. 20 $100 up to $200 $7. 80 $11. 60 $200 and over $10. 50 $16. 45 Vera selects standard shipping and the company bills her credit card $20. 78 for the total of the online purchase.

Vera has been over charged by $1. 13 for her purchase. D. Vera has been over charged by $3. 50 for her purchase.
For the total purchase, vera has been overcharged by $3. 50 for her purchase.
What will be the total purchasing price of the vera?We have information that
3 orders at 0.89$
[tex]=3\times 0.89=2.67[/tex]$
12 orders for 0.15$
[tex]=12\times0.15=1.8[/tex]$
for 1 order 2.99$
[tex]=1\times 2.99=2.99[/tex]$
and also 8.69$ for a photo album
so total amount = 2.67+1.8+2.99+8.69= 16.15$
Now 7% of the tax =[tex]16.15\times1.07=17.2805[/tex]
Thus the difference of the amount =20.78-17.2805=3.5$
