A coin is tossed 10 times. 4 of the 10 tosses result in heads. What is the THEORETICAL probability of landing on heads
Answer:
1 /2
Step-by-step explanation:
The theoretical probability is the possibility of an event occurring based on reasoning and not on the outcome of a trial or experiment. Hence, for the question above, the outcome of the tosses or trials would have no effect on the theoretical probability that a coin lands oon head or tail.
Theoretical probability of an event =
Favorable outcome / Total possible outcomes
Favorable outcomes = number of heads in a coin = 1
Total possible outcomes = number of faces on a coin = 2 (head and tail)
Therefore,
Theoretical probability of landing on head = 1 /2

Answer:
A) x = 6 y = 6√3
Step-by-step explanation:

Drag each tile to the correct box. Amanda, Derrick, and Todd attend the same high school. Each student works as the cashier one night a week at the school's concession stand. The number of items sold at the concession stand to the first 20 customers on three different nights is represented on the dot plots below. Find the interquartile range, IQR, for each dot plot. Then, place the students in order from greatest to least IQR.
Answer:
Amanda > Todd > Derrick
Step-by-step explanation:
Amanda's IQR- 3.5
Derrick's IQR- 2
Todd's IQR- 3
The solution is, ordering the IQR in descending order :
Emma, Sally, Olivia
What is IQR?The interquartile range (IQR) contains the second and third quartiles, or the middle half of your data set. Whereas the range gives you the spread of the whole data set, the interquartile range gives you the range of the middle half of a data set.
here, we have,
Writing out the points obtained from the dot plot, and applying the relevant formula, the Interquartile range of each dot plot is given below ;
Writing out each score on the dot plot to calculate the statistical values :
Emma's Scores:
6 , 7 , 8 , 8 , 9 , 9 , 9 , 10 , 10 , 11 , 11 , 11 , 11 , 11 , 12 , 13 , 13 , 13 , 13 , 14
Q1 = 1/4(n+1)th term
Q1 = (5th + 6th) terms
Q1 = (9 + 9) / 2 = 9
Q3 = 3/4(n+)th term
Q3 = (12 + 13) ÷ 2 = 12.5
IQR = Q3 - Q1
IQR = 12.5 - 9 = 3.5
Sally's Scores:
6 , 6 , 6 , 7 , 7 , 8 , 8 , 8 , 9 , 9 , 10 , 10 , 10 , 10 , 10 , 10 , 11 , 11 , 12 , 12 , 14
Q1 = 1/4(n+1)th term
Q1 = (7 + 8) ÷ 2 = 7.5
Q3 = 3/4(n+1)th term
Q3 = (10 + 11) ÷ 2 = 10.5
IQR = Q3 - Q1
IQR = 10.5 - 7.5 = 3
Olivia's Scores:
6 , 6 , 7 , 7 , 7 , 8 , 8 , 8 , 8 , 9 , 9 , 9 , 9 , 9 , 10 , 10 , 12 , 12 , 13 , 14
Q1 = 1/4(n+1)th term
Q1 = (7 + 8) ÷ 2 = 7.5
Q3 = 1/4(n+1)th term
Q3 = (10 + 10) ÷ 2 = 10
IQR = Q3 - Q1
IQR = 10 - 7.5 = 2.5
Therefore, ordering the IQR in descending order :

Will give brainliest if correct! Which of the following is not a solution to the inequality 3−(7−2x)>−8?
A) -3
B) -1
C) 0
D) 1
Answer:
-3
Step-by-step explanation:
3-(7-2x) > -8
get rid of the parentheses because there is a minus sign before them
3-7+2x > -8
replace x with all the numbers (one by one not all at once) and see if the equation is correct until you find the number that makes it incorrect.
EXAMPLE:
3-7+2(1) > -8 parentheses next to a number means multiply
3-7+2 > -8
3-7 = -4
-4 + 2 = -2

Find the dividend if quotient is x–3, remainder is 7x–9 and divisor is x^2-2
Answer:
[tex]\implies Dividend = x^3-3x^2+4x-3[/tex]
Step-by-step explanation:
Given :-
Quotient is x–3, remainder is 7x–9 and divisor is x^2-2 .And we need to find out the Dividend. We know that ,
[tex]\implies Dividend = Quotient\times Divisor + Remainder [/tex]
Substituting the respective values :-
[tex]\implies Dividend = (x-3)(x^2-2)+7x-9 \\\\\implies Dividend = x^3-2x-3x^2+6+7x-9 \\\\\implies Dividend = x^3-3x^2+4x-3[/tex]
The square pqrs is shown.
A dilation image of square PQRS with a scale factor 5 and center at the origin is drawn. The image is square p'q'r's
What is the ratio of the length of p'q' to the length of q'r?
Answer:
1:1
Step-by-step explanation:
The ratio would be 1:1 since it's a square, the sides will always be the same. In a square ,all sides are the same length. If they are not, then it wouldn't be a square.

1. The graph below shows Calvin’s distance from home throughout the day
on Friday. He spent about 7 hours at school, 1 hour at a friend’s house,
and about 30 minutes at a store.
Answer:
Step-by-step explanation:
The solution is Option C.
The section on the graph which represents the equation at which Calvin spends his time at friend's house is section S
What is an Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
On a graph, a linear equation forms a straight line. On a graph, a nonlinear equation produces an S-curve, a bell curve, or another nonlinear shape.
Let the total time spend by Calvin at school = 7 hours
Let the total time spend by Calvin at friend's house = 1 hour
Let the total time spend by Calvin at a store = 30 minutes
From the graph , we can see that
The section Q represents the line from x = 1 to x = 8 which means a total time of 7 hours is spend by Calvin at school
And , section S represents the line from x = 9 to x = 10 which means a total time of 1 hour is spend by Calvin at friend's house
And , section U represents the line from x = 10.5 to x = 11 which means a total time of 30 minutes is spend by Calvin at a store
Hence , the solution is section S of on the graph

What is the median of the data?
Answer: Median: 10
Step-by-step explanation:
Answer: 10
Step-by-step explanation: First you place the numbers in order from least to greatest (5,5,7,9,11,12,16,23) then you take away one from each side at a time so 5,23 then 5,16 etc. you end up with 9 and 11 left so you find the middle of 9 and 11 which is 10.
