If you were to flip the coin 15 times, how many times will the coin land on tails based on the experimental probability? Show your work in the box below the image.
Answers
Chance of tails(~0.466667%) times total times flipped( 15) = 6.99999999…=7
Basically just find the percent of tails and use that percent for the different amount of times the coin will be flipped.
Answer: 7
The coin will land 7 times tail based on the experimental probability.
What is Probability?Probability refers to potential. A random event's occurrence is the subject of this area of mathematics.
The range of the value is 0 to 1. Mathematics has incorporated probability to forecast the likelihood of various events.
The degree to which something is likely to happen is basically what probability means.
Given:
When the coin tossed 45 times.
Head= 24, tail = 21
So, fraction of appearing tail will be
= 21 / 45
= 0.466667
Now, if the coin tossed 15 times then the coin land on tails
= 15 x 0.466667
= 7

Sam is ordering shirts online. The shipping is a flat rate of $5.99, and each shirts costs $12.50. He spent $80.99 in total. How many shirts did he order
Answers
Based on the shipping rate and the price of the t-shirts, it can be concluded Sam ordered a total of 6 t-shirts.
What equation represents Sam's situation?5.99 + x12.50 = 80.99
x represents the number of t-shirts she bough, which is the focus of the equation.
Let's solve it:
5.99 + x12.50 = 80.99x12.50 = 80.99 - 5.99x12.50 = 75x = 75 / 12.50x = 6How many t-shirts did Sam order?Sam ordered 6 t-shirts.

A yard cleanup service charges a $345 fee plus $16.25 per hour. Another cleanup service charges a $213 fee plus $24.50 per hour. How long is a job for which the two companies' costs are the same?
Answers
The time for the job for which the two company are the same is 16
How to form the equation and find the cost?
A yard cleanup service charges a $345 fee plus $16.25 per hour. Therefore,
using linear equation,
y = mx + c
where
y = total costx = timeTherefore,
y = 345 + 16.25x
Another cleanup service charges a $213 fee plus $24.50 per hour. Therefore,
y = 213 + 24.50x
Hence, the time when both cost are the same is as follows;
213 + 24.50x = 345 + 16.25x
213 - 345 = 16.25x - 24.50x
-132 = -8.25x
x = 132 / 8.25

How are similar triangles related to each other?
Answers
Answer:
The corresponding angles are congruent. The corresponding sides all have the same ratio.
Step-by-step explanation:
Congruent means the angles are equal to each other. There are three pairs of angles. "Matching angles" (not a mathematical term) will be the same/equal/congruent.
The sides would only be same/equal/congruent if the triangles were congruent. For similar triangles, you can find a ratio of sides like big/little or little/big and if you set up the ratios of the matching sides, the ratio will be the same for all three pairs of sides. See image for example.

The Brand Blast normally charges a shirt is $13 if the Blast reduced the price of each shirt by $5 principal Howard paid $928 in all.
What is a linear equation?It is defined as the relation between two variables if we plot the graph of the linear equation we will get a straight line.
If in the linear equation one variable is present then the equation is known as the linear equation in one variable.
Let's suppose the normally Blast charge $x for each shirt
So according to the problem:
116(x-5) = 928
x = $13

The possible domain is:
The domain of the function is the set of possible values of d.
Because d represents the depth of water,
The starting value can take any value, less than 0

Points A and B are not on the unit circle.
Step-by-step explanation:
Recall that a "unit circle" has a radius of 1, and so if x² + y² ≠ 1, the point is not on a unit circle.
In A we apply the Pythagorean Theorem as follows: 1² + 1² = 2 ≠ 1.
Therefore, point (1, 1) is not a point on the unit circle.
In B: if we square the x and y components and add these squares together, we get 3/4 + 1/9, which does not equal 1. Point not on unit circle.
In C, we get 4/9 and 5/9, which eqals 1. This point C lies on the unit circle.
In D, we get 0.64 + 0.36 = 1, so this point does lie on the unit circle.
Thus: not on unit circle: A(1, 1), B(√3/2, 1/3)
On unit circle: D(0.8, -0.6), C(-2/3, √5/3)

Which statement would best describe the graph of the function?
The graph is a straight line that has a slope of 8.
The graph is a horizontal line at y = 16.
The graph starts flat but curves steeply upward.
The graph is a parabola that opens upward.
Answers
Answer:
The answer is
→ C.) The graph starts flat but curves steeply upward.
Step-by-step explanation:
Explaining option C:
The quick leaps in y-coordinates indicate that it continues to travel higher up faster and faster while the x-coordinates proceed continuously.
The first choice is incorrect since the slope formula yields a value of 15 for the slope. The second choice is incorrect since it is impossible for it to be a horizontal line unless x = 0, which it is not because it equals 2. The last choice is incorrect because, rather of continuously increasing in size, a parabola function begins to decrease in size (the vertex would be visible in the function if this was a parabola.)
Therefore, Option C.) The graph starts flat but curves steeply upward is your answer.
