A simulation of a person throwing a dart at a dartboard is run 140 times, and the player hits the dartboard 105 times. Using the results of the simulation, what is the experimental probability that the player does not hit the dartboard? Express your answer as a decimal.
Can someone please help me i am so confused.
Answer:
0.25
Step-by-step explanation:
If the person made it 105 out of 140 times, that can be written as a fraction: 105/140
Then, you just turn the fraction into a decimal by dividing the numerator by the denominator.
105 divided by 140 = 0.75
0.75 is the probability that it does hit the board, so we can subtract 0.1-0.75 to give us the probability that is doesn't hit the board. This would give us 0.25
Hope this helps
The experimental probability that the player does not hit the dartboard is,
⇒ 1 / 14
What is mean by Probability?The term probability refers to the likelihood of an event occurring. Probability means possibility. It is a branch of mathematics that deals with the occurrence of a random event. The value is expressed from zero to one.
Given that;
A simulation of a person throwing a dart at a dartboard is run 140 times, and the player hits the dartboard 105 times.
Hence, Number of not hit dartboard is,
⇒ 140 - 105
⇒ 35
Thus, The experimental probability that the player does not hit the dartboard is,
⇒ 35 / 140
⇒ 7 / 28
⇒ 1 / 14

The telephone company offers two billing plans for local calls. Plan 1 charges $29 per month for unlimited calls and Plan 2 charges $19 per month plus $0.05 per call.
a. Use an inequality to find the number of monthly calls for which Plan 1 is more economical than Plan 2.
b. Explain the meaning of the answer to part a.
Answer:
Step-by-step explanation:
wouldn't you do 29 x 19=551+0.05=551.05
Answer:
The number of monthly calls for which Plan 1 is more economical than Plan 2 is 200 calls If more than 200 calls are made, the plan 1 charge will be more than plan 2. Let the number of charges per month be x If plan 2 charges $16 per month plus $0.04 per call, this is expressed as 0.04x + 16 Price that pan 1 charges = $24 If Plan 1 is more economical than Plan 2, this is expressed as:0.04x + 16 > 24 Subtract 16 from both sides:0.04x + 16 - 16 > 24 - 16 0.04x > 8 x = 6/0.04 x = 200 This shows that if more than 200 calls are made, the plan 1 charge will be more than plan 2.
Consider the inequality x>7. Determine whether each value of x shown in the table makes this inequality true. Select Yes or No for each value.
WILL GIVE BRANLIEST
Answer:
No no yes yes no
Step-by-step explanation:
-22>7
this is not true because -22 is less than 7 and the inequality is going toward it.
-7>7
this is also not true because of the same reason.
13>7
This is true becuase 13 is greater than 7. If you can't tell which number is greater. Subtract the first number from the second; if it is positive, it is greater. If it is 0 then it is equal. If it is negative then it is less than.
5>7

Explain how You know that the quotient 47.3/10 is equal to the product 47.3 x0.1
(General question don’t use examples)
Answer:
The quotient 47.3/10 is equal to the product 47.3 x 0.1 because division and multiplication are inverse operations. In other words, dividing a number by another number is the same as multiplying it by the reciprocal of that number.
Step-by-step explanation:
The reciprocal of a number is defined as 1 divided by that number. For example, the reciprocal of 10 is 1/10, which is equal to 0.1.
Therefore, dividing 47.3 by 10 is the same as multiplying it by the reciprocal of 10, which is 0.1. This is why the quotient 47.3/10 is equal to the product 47.3 x 0.1.
This relationship between division and multiplication can be written as follows:
a/b = a x (1/b) = a x b^(-1)
where a and b are numbers, and b^(-1) is the reciprocal of b.
Answer:
The quotient 47.3/10 is equal to the product 47.3 x 0.1 because division and multiplication are inverse operations. In other words, dividing a number by another number is the same as multiplying it by the reciprocal of that number.

Tomas is a commercial real estate agent who earns a yearly salary of $82,500 and a 2.5% commission on his total sales. If Tomas sold properties that totaled $3.75 million in sales during one year, what are Tomas’s earnings for that year?
Answer:
$176,250
Step-by-step explanation:
Multiply $3.75 million by Tomas commission on his total sales.
Since you can't multiply a percentage you have to turn the commission into a decimal by moving it two spaces to the left. (Note: if it doesn't have a decimal add one add the end of the number then move it two spaces to the left)
$3,750,000 x .025 or 0.025 = $93,750
Add $93,750 to Tomas yearly salary
$93,750 + $82,500 = $176,250
So
If Tomas sold properties that totaled $3.75 million in sales during one year, his earnings for that year would be $176,250

A right triangle is drawn on graph paper. The length of the legs measure 1.5 centimeters and 2 centimeters. The length of the hypotenuse measures 2.5 centimeters. Write an equation using the triangle’s side lengths to show the Pythagorean Theorem holds true for the triangle.
The Pythagorean Theorem states that in a right triangle, the square of the length of the hypotenuse is equal to the sum of the squares of the lengths of the other two sides.
In this case, let's denote the lengths of the legs as a = 1.5 centimeters and b = 2 centimeters, and the length of the hypotenuse as c = 2.5 centimeters.
The equation using the triangle's side lengths to show the Pythagorean Theorem holds true for the triangle is:
a^2 + b^2 = c^2
Substituting the given values, we have:
(1.5)^2 + (2)^2 = (2.5)^2
2.25 + 4 = 6.25
6.25 = 6.25
Therefore, the equation holds true, confirming that the Pythagorean Theorem is satisfied for the given right triangle.

For a dilation centered at the origin with a scale factor of 3/2:
(a) original coordinates → final coordinates
R (-4,6) → R' (-6,9)
S (6,2) → S' (9,3)
T (-6,-4) → T' (-9,-6)
(b) (x, y) → ((3/2)x, (3/2)y)
How to determine a dilation mapping?To determine a dilation mapping, follow these steps:
Identify the center of dilation. This is the fixed point around which the dilation occurs.Determine the scale factor. The scale factor determines how much the image is stretched or shrunk. It can be a positive or negative number, but it cannot be zero.Apply the scale factor to each coordinate. To do this, multiply each coordinate by the scale factor, with the center of dilation as the origin.For example, if the center of dilation is (2, 3) and the scale factor is 2, the dilation mapping can be expressed as:
(x, y) → (2(x-2), 3(y-3))
This means that every point (x, y) is transformed into the point (2(x-2), 3(y-3)) after the dilation.

At 78°F, a certain insect chirps at a rate of 106 times per minute, and at 81°F, they chirp 112 times per minute. Write an equation in slope-intercept form that represents the situation.
Answer:
y=2x-50
Step-by-step explanation:
\(m=\frac{y^2-y^1}{x^2-x^1} = \frac{112-106}{81-78} =\frac{6}{3} =2\)
slope-intercept formula(substitute 81 for x, 112 for y, and 2 for m:
y=mx+b
112=2(81)+b
112=162+b
Then subtract 162 from both sides, and b=-50
Plug in all numbers into original equation
y=mx+b m=2 b= -50
So u get y=2x-50
