Answer:
Hence, Stacy will spin 6, 8.33 times out of her n = 50 attempts.
Step-by-step explanation:
Let us consider a success to get a 6. In this case, note that the probability of having a 6 in one spin is 1/6. We can consider the number of 6's in 50 spins to be a binomial random variable. Then, let X to be the number of trials we get a 6 out of 50 trials. Then, we have the following model.
We will estimate the number of times that she spins a 6 as the expected value of this random variable.
Recall that if we have X as a binomial random variable of n trials with a probability of success of p, then it's expected value is np.
Then , in this case, with n=50 and p=1/6 we expect to have number of times of having a 6, which is 8.33.

Given: ABCD is a quadrilateral, BC║AD, m∠ A = 90°
Prove: BD^2 − AC^2 = AD^2 − BC^2
Please Help!!! I need this for tonight!!
Answer:
Rearrange the equations that result from use of the Pythagorean theorem.
Step-by-step explanation:
Transversal AB crossing parallel lines AD and BC makes supplementary interior same-side angles A and B. Since A = 90°, B must be 90°. The Pythagorean theorem then applies in the right triangles ABC and ABD.
We can use that theorem to write two expressions for AB^2:
BD^2 -AD^2 = AB^2 = AC^2 -BC^2
The middle expression, AB^2, isn't needed beyond this point. Adding (AD^2 -AC^2) to both sides of the equation gives the desired result:
BD^2 -AC^2 = AD^2 -BC^2
Find the 70th term of the arithmetic sequence -26, -19, -12
Answer:
457
Step-by-step explanation:
The general term of an arithmetic sequence is given by ...
an = a1 +d(n -1)
where a1 is the first term (-26), and d is the common difference (7).
The 70th term of your sequence can be found by putting the numbers into this formula:
a70 = -26 +7(70 -1) = -26 +483
a70 = 457
The 70th term of the sequence is 457.

It is the same function just translated differently on the coordinate plane. The origin goes from being at (-4,-2) to (-6,3) so I switched those variables in the equation. Just remember that anything in the parenthesis has to be the inverse sign than what you would think.
Panat has assets that total $9,500. His liabilities total $1,900. Which expression will find Patrick's net worth?
$9.500-$1.900
$1.900-$9.500
$1.900-$9.500
$9.500-$1.900
Helppp
Answer:
D
Step-by-step explanation:
assets total - liabilities/deductions = net worth
his income is what his net worth it, but liabilities is what you dont have. its what you owe/need to pay/dont own. subtracting these two will give you your real net wroth.
The correct expression to find Patrick's net worth is D: $9,500 - $1,900.
What is the net worth?The difference between an individual's assets and liabilities is described as net worth.
As per the question, Patrick's assets are given as $9,500 and his liabilities are given as $1,900.
To find his net worth, we need to subtract his liabilities from his assets.
Thus, the expression for Patrick's net worth is:
Net worth = Assets - Liabilities
Net worth = $9,500 - $1,900
Net worth = $7,600
Therefore, Patrick's net worth is $7,600.

The box plot shows the number of home runs hit by 43 players during a baseball season which statement best describes the data
The following statement best describes the data as shown in the box plot-
The spread between the lower quartile and the median is greater than the spread between the upper quartile and the median.
Box PlotA box plot is a standardized way of displaying the distribution of data based on a five-number summary that is minimum, lower quartile, median, upper quartile and maximum.
How to read a box plot diagram?The lower quartile of the box plot is represented by the far left-hand side of the box. Here, it is [tex]9[/tex].
The upper quartile of the box plot is represented by the far right-hand side of the box. Here, it is [tex]19[/tex].
The median of the box plot is represented by the vertical bar of the box. Here, it is [tex]15[/tex].
The spread on the box plot is represented by the horizontal distance.
So, spread between the lower quartile and median [tex]=(15-9)=6[/tex]
Spread between the upper quartile and median [tex]=19-15=4[/tex]
[tex]6[/tex] is greater than [tex]4[/tex]
Hence, the spread between the lower quartile and the median is greater than the spread between the upper quartile and the median as shown in the box plot.

What mistake did Donte make?
He did not apply the distributive property correctly for 4(1 + 3i).
He did not distribute the subtraction sign correctly for 8 – 5i.
He added the real number and coefficient of i in 4(1 + 3i).
He added the two complex numbers instead of subtracted.
Answer:
He did not apply the distributive property correctly for 4(1 + 3i).

Express the inequality x≤−0.12 using interval notation.
Answer:
(0.12,∞)
Step-by-step explanation:
The inequality x>0.12 means "all numbers greater than 0.12." There is no upper end to the solution to this inequality. In interval notation, we express x>0.12 as (0.12,∞). Notice that the parenthesis symbol shows that the endpoint of the inequality, 0.12, is not included.
The inequality x ≤ - 0.12 is written in interval notation as,
⇒ x ∈ (- ∞, - 0.12 ]
What is Inequality?A relation by which we can compare two or more mathematical expression is called an inequality.
Given that;
The inequality is,
⇒ x ≤ - 0.12
Now, We can write the inequality in interval notation as;

The angle of elevation from the top of a building to the top of another is 45°.
The distance between the feet of these two buildings is 402 m.
What is the distance between the top of the two buildings?
Answer:
402m
Step-by-step explanation:
Set this up as a triangle and use trig to solve it:
tan(45) = y/402
y = 402*tan(45)
substitute: tan(45) = 1
y = 402 * 1
y = 402m

Many track runners believe that they have a better chance of winning if they start in the inside lane that is closest to the field. For the data below, the lane closest to the field is Lane 1, the next lane is Lane 2, and so on until the outermost lane, Lane 6. The table displays the starting positions for the winners of 240 competitions. Calculate the chi-square test statistic X2 used to test the claim that the probability of winning is the same regardless of starting position.
Starting Position 1 2 3 4 5 6
Number of Wins 33 44 32 36 45 50

b.15.541
c.9.326
d.6.750
Answer:
d) 6.750
The chi - square value = 6.750
Step-by-step explanation:
Given data
Starting Position 1 2 3 4 5 6
Number of Wins (O) 33 44 32 36 45 50
Step(i) :-
mean = [tex]\frac{33+44+32+36+45+50}{6} = \frac{240}{6} =40[/tex]
Expected frequency = 40
Number of Wins (O) : 33 44 32 36 45 50
Expected frequency(E) : 40 40 40 40 40 40
(O - E ) : -7 4 -8 -4 5 10
(O-E)² : 49 16 64 16 25 100
[tex]\frac{(O-E)^2}{E}[/tex] : 1.225 0.4 1.6 0.4 0.625 2.5
Step(ii):-
The χ² test
χ² = ∑ [tex]\frac{(O-E)^2}{E}[/tex]
χ² = 1.225 + 0.4 + 1.6 + 0.4 +0.625 +2.5 = 6.75
The chi - square value = 6.750
Final answer:-
The chi - square value = 6.750
