A coin has a heads side and a tails side.
Chuck flips the coin 80 times.
About how many times will it land heads up?
25
40
50
Answer: 40
Step-by-step explanation: the reason why is that there's a 50/50 chance that it could land on heads or tails.
Answer:
40
Step-by-step explanation:
A coin has a 1/2 chance to land on both heads and tails sides (50/50), so cut 80 in half (80/2), and you get 40.

Please answer this, Thanks! (i'll give brainliest if right)
Answer:
see explanation
Step-by-step explanation:
12 is 2 × 6 then 6 × 9 = 54
45 is 9 × 5 then 2 × 5 = 10
Then the ratios are
2 : 9, 12 : 54 and 10 : 45

Answer:
Use absolute difference
Step-by-step explanation:
Given
The given parameters can be represented as:
[tex]Expense > Income[/tex]
[tex]Income - Expense< 0[/tex]
Required
Eliminate negative difference
To eliminate negative difference, Sara has to make use of absolute difference when calculating the difference between her income and expense.
Take for instance:
[tex]Income = 10[/tex]
[tex]Expense = 12[/tex]
The difference between both is:
[tex]Income - Expense = 10 - 12[/tex]
[tex]Income - Expense = -2[/tex]
But if she uses absolute difference, the result will be:
[tex]|Income - Expense| = |10 - 12|[/tex]
[tex]|Income - Expense| = |-2|[/tex]
[tex]|Income - Expense| = 2[/tex]

The formula for the volume of a rectangular prism is volume = length × width × height.
Which of the following is the BEST estimate of the volume of the rectangular prism below?
A. 16 cubic units
B. 54 cubic units
C.90 cubic units
D. 120 cubic units
Answer:
C
Step-by-step explanation:
The formula to work out the volume of a rectangular prism is:
V= w*h*l
Let's plug these nums. in:
V = (2.9)(9.7)(3.4) = 95.642
The closest answer is C ~ 90 cubic units

Step-by-step explanation I did da quiz and got it correct.
match each function with its rate of growth or decay
Answer:
y=5(1.05)^t=5% rate of growth
f(t)=50(0.95)^t=5% rate of decay
g(t)=50(1.5)^t=50% rate of growth
y=5(.5)^5=50% rate of decay
Step-by-step explanation:
y=5(1.05)^t= 1+x=1.05. x=0.05. 0.05= 5%, 5% rate of growth,
f(t)=50(0.95)^t=1-x=0.95, x=-0.05=-5%=5% rate of decay
g(t)=50(1.5)^t=1+x=1.5, x=0.5=50%, 50% rate of growth
y=5(.5)^5=1+x=0.5, x=-0.5=50%, 50% rate of decay
If this helps please mark as brainliest
The correct matching of the functions y = 5 · (1.05)ⁿ, y = 50 · (0.95)ⁿ, y = 50 · (1.5)ⁿ, and y = 5 · (0.05)ⁿ will be growth rate is 5%, the decay rate is 5%, the growth rate is 50%, and the decay rate is 50%, respectively.
What is an exponent?Consider the function:
y = a (1 ± r)ˣ
Where x is the number of times this growth/decay occurs, a = initial amount, and r = fraction by which this growth/decay occurs.
If there is a plus sign, then there is exponential growth happening by r fraction or 100r %
If there is a minus sign, then there is exponential decay happening by r fraction or 100r %
The functions are given as,
y = 5 · (1.05)ⁿ
y = 5 · (1 + 0.05)ⁿ
The growth rate is 5%.
y = 50 · (0.95)ⁿ
y = 50 · (1 - 0.05)ⁿ
The decay rate is 5%.
y = 50 · (1.5)ⁿ
y = 50 · (1 + 0.5)ⁿ
The growth rate is 50%.
y = 5 · (0.05)ⁿ
y = 5 · (1 - 0.5)ⁿ
The decay rate is 50%.
The correct matching of the functions y = 5 · (1.05)ⁿ, y = 50 · (0.95)ⁿ, y = 50 · (1.5)ⁿ, and y = 5 · (0.05)ⁿ will be growth rate is 5%, the decay rate is 5%, the growth rate is 50%, and the decay rate is 50%, respectively.

Answer:
1. x<14
2. x≥50
3. x≤8
4. x≤75
Answer:
1. <
2. ≥
3. ≤
4. ≤
Step-by-step explanation:
since the first one says “less than” the opening of the sign is pointed towards the 14
for the second it says “at least” so it has to be 50 dollars or more
for the third it is “at most” 8. that means that the highest number is 8 so there can’t be a number greater than that. but they can be less
for the fourth it’s “no more” than 75 degrees so that means it has to be 75 degrees or less. It can’t be more

For what value of A is the graph of Ax+6y = 12 perpendicular to the graph of 2x−3y = 4?
The value of A for the two graphs will be 9.
What is coordinate geometry?A coordinate plane is a 2D plane that is formed by the intersection of two perpendicular lines known as the x-axis and y-axis. A coordinate system in geometry is a method for determining the positions of the points by using one or more numbers or coordinates.
The two equations are Ax+6y = 12 and 2x−3y = 4. The value of A will be calculated as,
2x−3y = 4
y = 2/3x - 4/3
Ax+6y = 12
y = -A/6x +2
The slope of one graph will be inverse and the opposite to the other graph for the line to be perpendicular,
-3 / 2 = -A / 6
A = 9
