A computer generates 90 integers from 1 to 5 at random. The results are recorded in the table.
What is the experimental probability of the computer generating a 1?

20%
30%
40%
Outcome Number of times
outcome occurred
1 36
2 11
3 13
4 12
5 18
Answer:
40%
Step-by-step explanation:
36/90 integers are 1, so the experimental probability is ...
p(1) = 36/90 = 0.40 = 40%
Using it's concept, it is found that there is a 0.4 = 40% experimental probability of the computer generating a 1.
What is a probability?A probability is given by the number of desired outcomes divided by the number of total outcomes.
For an experimental probability, these numbers of outcomes are taken from previous trials. In this problem, there have been 90 trials, and 36 resulted in a 1 being generated, hence:
p = 36/90 = 0.4.
0.4 = 40% experimental probability of the computer generating a 1.

What are the solutions of 8x2 = 6 + 22x? Check all of the boxes that apply. x = -3 x = -1/4 x = 3 x = 6
Answer:
x = -1/4
x = 3
The solutions of the given quadratic equation 8x² = 6 + 22x will be x = -1/4 and x = 3 thus, option (B) and (C) is correct.
What is a quadratic equation?An algebraic equation of the second degree in x is a quadratic equation. The quadratic equation is written as ax2 + bx + c = 0, where x is the variable, and a must not be zero.
For example, 3x² + 6x + 8 = 0 here x has the highest term as 2 and the coefficient of x² is not zero.
As per the given quadratic equation,
8x² = 6 + 22x
The roots must satisfy the above equation,
8(-3)² = 6 + 22(3)
72 = 72
And,
8(-1/4)² = 6 + 22(-1/4)
8/16 = 6 - 11/2
1/2 = 1/2
Hence "The solutions of the given quadratic equation 8x² = 6 + 22x will be x = -1/4 and x = 3"

if sugarless gum sells at 2 pieces for $.25, then what would 10 pieces cost?
Answer:
My answer is 10 pieces = $1.25
Step-by-step explanation:
If 2 pieces cost $.25 then you need to multiply $.25/2, because $.25 is for two pieces. So, when you divide that you get $0.125 so then take the $0.125 and multiply by 10 to get $1.25.
ALTERNATE SOLUTION:
If 2 pieces cost $.25 then you need to multiply $.25 x 5, because $.25 is for 2 pieces. So, when you multiply that you get $1.25.
The cost of 10 pieces of sugarless gum if 2 pieces cost $.25 is $1.25
Cost of itemsGiven:
Cost of 2 pieces = $.25cost of 10 pieces = $xRatio of pieces to cost
2 : .25 = 10 : x
2 / .25 = 10 / x
cross product2 × x = .25 × 10
2x = 2.5
divide both sides by 2x = 2.5/2
x = $1.25
Therefore, the cost of 10 pieces of sugarless gum is $1.25

y=27.75
x=13.5
Step-by-step explanation:
(5x-17)+(3x-11)=180 (supplementary angle rule)
8x-28=180
8x=180+28
x=108/8
x=13.5
(3x-11)+90+(2y+5)=180 (supplementary angle rule)
29.5+90+2y+5=180 (replace x by 13.5)
2y=55.5
y=55.5/2
y=27.75

Amy is six years older than her brother Leo. Leo is seven years old. If n stands for Amy's age, which of these sentences could be used to find her age?
Answer:
n = 6+x
Step-by-step explanation:
Given that:
Amy is 6 years old than her brother Leo
Let consider the age of Leo to be x since we are not yet told how old is Leo
Then Amy is 6+x
Now, we know that Leo is seven years old,
i.e x = 7
If n stands for Amy's age,
Then, the algebraic expression showing how old is Amy's age can be expressed as n = 6+x
Amy's age (n) = 6+7
Amy's age (n) = 13
To solve any word problem, we need to define our conditions into system of the equations. Thus, Amy's age is 13 years.
Amy is six years older than her brother Leo.
Leo's age is seven years.
It is given in the question that Amy's age stands for 'n'.
Thus, according to the given conditions from the question.
The expression that defines the age of Amy is given below.
[tex]\rm{Amy's\;Age}=7+\rm{Leo's\;Age}\\n=7+6\\n=13[/tex]
Thus, Amy's age is 13 years.

Determine if x = 1 is the solution to this linear equation. 3x - 6(5x + 5) = 9x + 6 Is x = 1 the solution? No. When 1 is substituted for the variable, the result is a true statement. No. When 1 is substituted for the variable, the result is a false statement. Yes. When 1 is substituted for the variable, the result is a true statement. Yes. When 1 is substituted for the variable, the result is a false statement.
Answer: No. When 1 is substituted for the variable, the result is a false statement
Step-by-step explanation:
3x - 6(5x + 5) = 9x + 6
3x - 30x - 30 = 9x + 6
-27x -30 = 9x +6
-27x - 9x = 30 +6
-36x = 36
x = -1.
Substitute with x = -1 :
-3 - 6(-5 + 5) = -9 +6
-3 -30 + 30 = -3
-3 = -3
Therefore, the correct option is:
No. When 1 is substituted for the variable, the result is a false statement
Answer:
(B.)No. When 1 is substituted for the variable, the result is a false statement
