HI PLEASE HELP AH - ill mark brainliest !
if you flip three coins, the probability of getting three heads is 1/8. Interpret this probability.
The interpretation of the probability is there is a 12.5% chance of obtaining three heads when three coins are flipped
The probability is given as:
[tex]\mathbf{Pr = \frac 18}[/tex]
The above represents the probability of flipping a head three times.
Express as decimal
[tex]\mathbf{Pr = 0.125}[/tex]
Express as percentage
[tex]\mathbf{Pr = 12.5\%}[/tex]
This means that, there is a 12.5% chance of obtaining three heads when three coins are flipped

1 pack of cigarettes contains 20 cigarettes. Each cigarette smoked is said to reduce a person's life expectancy by 11 minutes. If a person smoked one pack per day for 25 years, how much shorter would their life possibly be? In minutes: In days: In hours: In years: bruh, heaLP
Answer:
Step-by-step explanation:
1 pack per days means 20 cigarettes a days each cigarette reduces life by 11 minutes. which is 220mins per day
25*365*24*60 =13140000mins originally
1) 25 years in minutes will be
reduction of life due to smoking = 220*365*25= 2007500minutes
2)In days
originally = 9125days
after smoking=220/24*60=0.1527*365*25= 1393days are reduced
3)In hours
originally = 219000hrs
reduced life =3.67*365*25= 33488.75hrs

Eleanor was looking to save money and make her home more energy efficient. She heard about LED
light bulbs but wanted to calculate the actual cost per year before buying them. Eleanor found that
incandescent bulbs cost $0.01 per hour in electricity, while LED's cost $0.0022 per hour. If the average
home has 65 light bulbs and has their lights on for 4 hours per day, what is the savings for 1 year for
Eleanor to switch all of her light bulbs to LED's?
Find the value of x
(9x-38)+(4x+23)=180
Answer:
x=15
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
9x−38+4x+23=180
9x+−38+4x+23=180
(9x+4x)+(−38+23)=180(Combine Like Terms)
13x+−15=180
13x−15=180
Step 2: Add 15 to both sides.
13x−15+15=180+15
13x=195
Step 3: Divide both sides by 13.
13x/13=195/13
Answer:
15
Step-by-step explanation:
9x-38+4+23=180
13x-15=180
13x=195
x=15

Determine if the sequence is arithmetic or geometric, and find the common difference or ratio.
x 1 2 3 4
f(x) 5 −5 −15 −25
Arithmetic, common difference = −10
Arithmetic, common difference = −1
Geometric, common ratio = −10
Geometric, common ratio = −1
Answer:
The sequence is arithmetic with a common difference of -10
Step-by-step explanation:
From the question, we want to determine if the sequence is arithmetic or geometric
From the question
f(1) = 5
f(2) = -5
f(3) = -15
Mathematically for the common difference;
f(3) - f(2) = f(2) - f(1)
Since;
-15-(-5) = -5-5
-10 = -10
Since the common difference here is same , then the sequence is arithmetic with a common difference of -10

The length of a rectangle is twice the width. The area of the rectangle is 80 square units. Notice that you can divide the rectangle into two squares with equal area. How can you estimate the side length of each square? Estimate the length and width of the rectangle.
Answer:
Width of the rectangle = 6.325 units
Length of the rectangle = 12.65 units
Side length of the square the 6.325 units.
Step-by-step explanation:
The length of a rectangle is twice the width. The area of the rectangle is 80 square units.
The area of the rectangle = Length × Width
Length = 2W
80 square units = 2W × W
80 = 2W²
W² = 80/2
W² = 40
W = √40
Width of the rectangle = 6.3245553203 units
Approximately = 6.325 units
Length = 2 × Width
= 2 × 6.325
= 12.65 units
• Notice that you can divide the rectangle into two squares with equal area. How can you estimate the side length of each square?
We you divide a rectangle into 2 squares,
The length is divided into two.
Hence, the length of the rectangle = 12.65 units
12.65 units ÷ 2 = 6.325 units.
Hence, the side length of the square the 6.325 units.

The number of rectangles and combinations:
1 rectangle = 62 rectangles = 53 rectangles = 44 rectangles = 35 rectangles = 26 rectangles = 1Total
6 + 5 + 4 + 3 + 2 + 1 = 21Now the number of,
Rectangles and combinations are,
→ 1 rectangle = 6
→ 2 rectangles = 5
→ 3 rectangles = 4
→ 4 rectangles = 3
→ 5 rectangles = 2
→ 6 rectangles = 1
Then the total number is,
→ 6+5+4 + 3+2+1
→ 15 + 6 = 21
Hence, total number is 21.

Answer:
a) Angle XBC = 55⁰ because its correspond to Angle AXY which is equal to 55⁰ and corresponding angles are equal.
b)Angle BXC = 70⁰
Step-by-step explanation:
b) Since XB = XC, triangle BXC is therefore an isosceles triangle.
Angle XBC = Angle XCB
Sum of interior angles of a triangle = 180⁰
55⁰ + 55⁰ + Angle BXC = 180⁰
110⁰ + Angle BXC = 180⁰
Angle BXC = 180⁰- 110⁰
= 70⁰

The formula is [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]. Here, we can plug in values where x2 = -6, x1 = -4, y2=-4, and y1 = 7. Solving, we get the slope is 11/2 or 5.5.
Maria makes $6.00 an hour plus 5% commission for telephone sales. Yesterday, Maria worked 8 hours and had sales of $600.00. How much did Maria make yesterday? Explain your answer.
Given:
Maria makes $6.00 an hour plus 5% commission for telephone sales.
Working time = 8 hours
Sales = $600.00.
To find:
The amount that Maria make yesterday.
Solution:
We know that,
1 hour = $6.00
8 hour = 8 × $6.00 = $48.00
Commission = 5% of telephone sales
Sales = $600.00.
[tex]Commission=5\times 6[/tex]
[tex]Commission=30[/tex]
Total amount that Maria make yesterday is the sum of total hourly changes plus commission.
[tex]\$48.00+\$30.00=\$78.00[/tex]
Therefore, the required amount is $78.00.
Solve for H: A = L ⋅ W ⋅ H
H = A times W over L
H = W times L over A
H = L times A over W
H = A over quantity L times W
Answer:
The answer would be
H = A over L times W
Step-by-step explanation:
This is because, when you multiply the L, W, and H you end up getting A. This means that A is the biggest number. We automatically can tell that H is what were looking for so putting those two things together we have this: H = A over ???
The ??? would have to be L times W because those are the only things left and they get multiplied together which in the end leaves us with
H = A over L times w
aka
H=A/LxW

Answer:
first and third quadrants
the answer B
Step-by-step explanation:
on the first quadrant x and y are both positive
in the second one x is negative and y positive so -x/y=-1
on the third quadrant x and y are both negative
so -x/-y=1
on the fourth quadrant x is positive and y negative so
x/-y=-1
here, in all cases x and y are taken the same length that's why we take always 1 or -1

What is the slope of a line parallel to the line whose equation is 5x+y=-9
Answer:
slope = - 5
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c (m is the slope and c the y- intercept )
Given
5x + y = - 9 ( subtract 5x from both sides )
y = - 5x - 9 ← in slope- intercept form
with slope m = - 5
Parallel lines have equal slopes, thus
The slope of a parallel line to the given equation is m = - 5
