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.
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

A shape is made by these three squares. What is the perimeter of new shape below:
What is the radius of a cone whose volume is 50 cubic units and whose height is 6 units?
Answer:
Radius = 2.8
Step-by-step explanation:
V = 1⁄3 πr² × h
50 = 1⁄3 πr² × 6
50 = 1⁄3 × 22⁄7 × r² × 6
50 = 22⁄21 × r² × 6
50 = 22⁄21 × 6 × r²
50 = 6.286 × r²
50 = 6.286r²
50/6.286 = 6.286r²/6.286
r² = 7.954
r = √7.954
r = 2.820

Amira buys cookies and onions at the store.
She pays a total of $51.40.
She pays a total of $6.18 for the cookies.
She buys 7 bags of onions that each cost the same amount.
How much does each bag of onions cost?
The cost of each bag of onions that was purchased by Amira given the total amount spent and the cost of cookies is $6.46.
How much was spent on a bag of onion?
The first step is to determine the total cost of the 7 bags of onions.
Total cost of the 7 bags of onions = total amount spent - cost of cookies
$51.40 - $6.18 = $45.22
Now, divide the total cost of the 7 bags of onions by 7.
Cost of one bag of onion = 45.22 / 7 = $6.46

Answer:
47.5
Step-by-step explanation:
The formula for the area of half a circle is (pi * radius^2)/2
diameter = 11
pi = 3.14
radius = diameter/2 = 11/2 = 5.5
A = (3.14 * 5.5^2)/2
A = 94.985/2
A = 47.4925

The following information is known about a savings account.
Time = 6 years
Interest rate = 1.9%
Principal = $850
What amount of total interest will be earned at the end of year 6?
$16.15
$96.90
$946.90
$9,690.00
Answer:
96.90
Step-by-step explanation:
850 * .019 * 6 =
This is simple interest ( no compounding interest)
Answer:
$96.90
Step-by-step explanation:
Let's find 1.9% of our amount, which is $850.
1% of 850 = 8.5
we need to get 1.9%, so lets multiply our current 1 percent by 1.9, to get what 1.9% would be.
1% of 850 = 8.5
x1.9 x1.9
1.9% = 8.5 x 1.9
1.9% = $16.15
This means that every year, the savings account gains $16.15 in interest. However, this doesn't account for all 6 years. So we multiply 16.15 by 6, for the 6 years that the money is in the saving account for.
$16.15 x 6 = $96.90 !
So, the total interest is $96.90 :)
-8x + 5 greater than or equal to -3
please solve this equation
Answer:
The greater than or equal to sign is:
>= or ≥.
Now let's solve for this inequality.
-8x + 5 ≥ -3
First, we need to get rid of any constants.
Get rid of a constant by performing the inverse operation of it, we always apply this to both sides of an inequality.
The inverse operation of addition (since it is a positive 5) is subtractions.
So, we subtract 5 from both sides;
-5 -5
Now we have:
-8x ≥ -8
Now, all we need to do is isolate x from it's co-efficient, 8.
To do that, we also utilize the inverse operation.
The inverse operation of multiplication (since -8 is being multiplied by x) is division, we apply this to both sides of this inequality.
So, we divide by -8 from both sides;
÷ -8 ÷ -8
And we'll end up with:
x ≥ 1, therefore the solution to this inequality is 1.

What are mean?The mean is the average value which can be calculated by dividing the sum of observations by the number of observations.
The mean of the seventh grade is given as 33.
The mean of the eighth grade is given as 30.
The correct statement is A because the mean absolute deviation of an eighth-grade class is less than that of a seventh-grade class.
Also, the class size is larger on average for seventh-grade classes (33 > 30).

If a rectangle has a length that is three times the width increased by 4. Find the dimensions of both the length and width if the
perimeter of the rectangle is 80 centimeters
Answer:
Step-by-step explanation:
Formula
The formula for perimeter is
P = 2L + 2w
Givens
Let the width = w
Length = 3w + 4
P = 80 cm
Solution
P = 2L + 2w
80 = 2(3w + 4) + 2w Remove the brackets
80 = 6w + 8 + 2w Combine
80 = 8w + 8 Subtract 8 from both sides
80-8 = 8w + 8-8 Combine
72 = 8w Divide both sides by 8
72/8 = 8w'8
9 = w
Answer
w = 9
L = 3*w + 4
L = 3*9 + 4
L = 31
