Answer:
Kindly check explanation
Step-by-step explanation:
Given that :
Number of tosses / trials = 20
Number of heads = 5
The experimental probability = the actual output of am event when an experiment or test is carried out :
Experimental probability = number of occuences / number of trials
That is :
P(head) = 5 / 20 = 1/4
Theoretical probability could be regarded as the expected output of an event based on the mathematical calculation :
Required outcome / Total possible outcomes
Theoretical probability P(head) in a toss = 1/2

Which function is equivalent to g(x) = x2+ 15x - 54?
Answer:
g(x) = (x+18) (x-3)
Step-by-step explanation:
x²-3x+18x-54
x(x-3)+18(x-3)
(x-3)(x-18)
The function equivalent to [tex]g(x) = x^{2} +15x-54[/tex] is [tex](x - 3) (x- 18)[/tex].
Here, the function is given as;
[tex]g(x) = x^{2} +15x-54[/tex]
What is Function?
A function is defined as a relation between a set of inputs having one output each.
Now, function is given as;
[tex]g(x) = x^{2} +15x-54\\g(x) = x^{2} +18x-3x-54\\g(x) = x(x+18)-3(x+18)\\g(x) = (x+18)(x-3)[/tex]
Hence, The function equivalent to [tex]g(x) = x^{2} +15x-54[/tex] is [tex](x - 3) (x- 18)[/tex].

one number is two more than triple a second number. Their sum is 30. what is the smaller number
Answer:
7
Step-by-step explanation:
We can solve this problem by making an equation.
Let x represent the second number
3x + 2 will be the first number because it is 2 more than triple x
This makes our equation:
3x + 2 + x = 30
Combine like terms
4x + 2 = 30
Subtract 2 from both sides
4x = 28
Divide both sides by 4
x = 7
The smaller number aka the second number is 7

If tax was 8.25% on the $220 total for the items purchased at Target, what was the total cost of the items including tax?
Answer:
$238.15
Step-by-step explanation:
8.25% = 8.25/100 or 0.0825
Multiply 0.0825 and 220 to get $18.15. That's how much the tax is.
Add 220 and 18.15 to get $238.15
Answer:
$238.15
Step-by-step explanation:
To find the total cost of the items including tax you will need to multiply the cost of the items by the decimal form of 8.25%.
The decimal form of 8.25% is .0825. When turning percents to the decimal form we move the decimal two places to the left.
Now we multiply!
(220)(.0825) = 18.15
Now add 18.15 onto the 220 to find the total cost including tax:
220 + 18.15 = 238.15
Therefore, the total cost of the items including tax is $238.15.
I hope this helps!!
