The integer 8 represents the amount lost each time the pass was used.

Division is one of the operation in mathematics where number is divided  into equal parts as that of a definite number.

Given that, every time Ezequiel rides the bus, money is deducted from the value of the pass.

He rode 9 times and $72 was deducted from the value of the pass.

Let x be the integer that represents the amount deducted each time.

The amount deducted after 9 times is 9x.

9x = 72

We have to divide 72 into 9 parts to know the value of x.

x = 72 / 9 = 8

Hence Ezequiel lost $8 each time the pass was used.

A)  The mean of 2018 scores: μ₂₀₁₈ = 75

 The mean of 2019 scores: μ₂₀₁₉ = 75

 The standard deviation of 2018 scores: s₂₀₁₈ = 2.07

 The standard deviation of 2019 scores: s₂₀₁₉ = 5.26

B) The primary difference is that variation is higher in the 2018 season than the 2019 season.

A)

We know that the mean is nothing but the sum of all scores divided by the number of scores.

Thus the mean for 2018 scores is:

μ₂₀₁₈ = (73 + 77 + 78 + 76 + 74 + 72 +74 + 76)/8

μ₂₀₁₈ = 75

Similarly the mean for 2019 scores is:

μ₂₀₁₉ = (70 + 69 + 74 + 76 + 84 + 79 + 70 + 78)/8

μ₂₀₁₉ = 75

We know that the formula for the standard deviation is:

[tex]s=\sqrt{\frac{\sum (x_i - \bar{x})^2}{n-1} }[/tex]

where s sample standard deviation

n the size of the sample

[tex]x_i[/tex] each value from the sample

[tex]\bar{x}[/tex] the sample mean

Using this formula, the standard deviation for 2018 scores is:

s₂₀₁₈ = [tex]\frac{\sqrt{ (73-75)^2 + (77-75)^2 + (78-75)^2 + (76-75)^2 + (74-75)^2 + (72-75)^2 +(74-75)^2 + (76-75)^2} }{7}[/tex]

s₂₀₁₈ = 2.07

And the standard deviation for 2019 scores is:

s₂₀₁₉ = [tex]\frac{\sqrt{ (70-75)^2 + (69-75)^2 + (74-75)^2 + (76-75)^2 + (84-75)^2 + (79-75)^2 +(70-75)^2 + (78-75)^2} }{7}[/tex]

s₂₀₁₉ = 5.26

Referring to the given kite, the length of the other diagonal. DF, is 21 cm.

A kite is a quadrilateral shape, meaning it has four sides. The two pairs of adjacent sides are of equal length, while the opposite sides are not.

The shape of a kite is typically described as having two pairs of congruent adjacent sides that are connected by two diagonal lines that intersect at a right angle. The diagonal lines of a kite are perpendicular to each other, and the shorter diagonal bisects the longer diagonal.

Let's denote the point of intersection of the two diagonals as O.

Since the two diagonal intersect at a right angle, diagonal DF is perpendicular to diagonal EG.

DG = 13 cm

FG = 20 cm

OG = 1/2 EG = 1/2 x 24 = 12 cm

Using the Pythagorean Theorem:

OD = √(DG² - OG²)

     = √(13² - 12²) = 5 cm

OF = √(FG² - OG²)

     = √(20² - 12²) = 16 cm

DF = OD + OF

Step-by-step explanation:

We are told that Michael's race numbers are:

5.25 miles

45.75 minutes

Divide the miles by the minutes to get mIchael's running rate:

0.114754098 mi/min

This result matches option B. " Michael's average pace was about 0.11 miles per minute."

======

Check all the answer options:

A. Michael's unit rate of minutes per mile was about 8.7.  

  Take 0.11475409 mi/min and invert it to find min/mile:

      1/(0.11475409 mi/min) = 8.71 min/mile

This is a correct statement.

B. Michael's average pace was about 0.11 miles per minute.

From above:  This is a correct statement.

C. Michael's unit rate of minutes per mile was about 6.9.

Take the given numbers:   (45.75 minutes)/(5.25 miles) = 8.71 min/mile

This is not a correct statement.

D. Michael's average speed during the race was about 6.9 miles per hour.  

Take the calculated rate of 0.11475409 mi/min and covert it to miles/hour:

  Use the conversion factor (60 min/1 hr)

   (0.11475409 mi/min)*((60 min/1 hr)) = 6.89 miles/hr

This is a correct statement.

E.  Michael ran about 8.7 miles in 1 minute.

We know from above that he runs at 6.89 miles per hour.  Running 8.7 miles in 1 minute  would mean he is running at (8.7)*(60) = 413 miles/hour.    

Perhaps he had some good energy bars, but the data do not support this conclusion.

This is not a correct statement.

b.) A high correlation can indicate a relationship but cannot prove causation.

Correlation measures the strength and direction of the relationship between two variables, but it does not necessarily imply causation. A high correlation means that there is a strong linear relationship between the two variables, but it does not indicate whether one variable causes the other. There can be other factors that influence the relationship. Therefore, it is important to use other methods, such as experiments or observational studies, to determine causation. Correlation is useful for identifying associations between variables, but it cannot be used as evidence of a causal relationship.

The orthocenter of ▲ABC is the point (27/4, 17/4)

What is Orthocenter in coordinate geometry?

Any triangle's three altitudes are contemporaneous line segments (they intersect in a single point), and this point is known as the triangle's orthocenter.

To find the orthocenter of ▲ABC, we need to first find the altitude lines of the triangle, which are the perpendicular lines from each vertex to the opposite side. The point where these three lines intersect is the orthocenter.

The slope of this line is:

BC = (-1 - (-4)) / (-1 - 5)

BC = 3/2

Using point-slope form, the equation of the line BC is:

[tex]y -y_{b} = m_{BC} (x - x_{b} )[/tex]

y - (-4) = (3/2)(x - 5)

y = (3/2)x - 17/2

To find the altitude from vertex A to BC, we need to find the equation of the line passing through A and perpendicular to BC. The slope of this line is the negative reciprocal of the slope of BC:

[tex]m\ altitude_A = -2/3[/tex]

The point-slope form of the equation of the altitude from A is:

[tex]y -y_{A} = m_{BC} (x - x_{A} )[/tex]

y - 5 = (-2/3)(x - 5)

y = (-2/3)x + 25/3

Similarly, we can find the equations of the altitudes from vertices B and C to the opposite sides AC and AB, respectively:

Altitude from B to AC:

[tex]m_{AC} = \frac{(y_{C} -y_{A})}{(x_{C} -x_{A})} \\\\m_{AC} = \frac{-3}{2}[/tex]

AC = 2/3

y - (-4) = (2/3)(x - 5)

y = (2/3)x - 2/3

Altitude from C to AB:

[tex]m_{AB} =\frac{(y_{B}- y_{A})}{(x_{B}- x_{A})} \\[/tex]

= (-4 - 5) / (5 - 5)

= undefined

x = -1

Now, we need to find the point of intersection of these three altitudes, which is the orthocenter. To do this, we can solve the system of equations formed by the three altitude lines:

y = (3/2)x - 17/2

y = (-2/3)x + 25/3

y = (2/3)x - 2/3

Substituting the third equation into the first two equations, we get:

(2/3)x - 2/3 = (-2/3)x + 25/3

(4/3)x = 9

x = 27/4

Substituting x = 27/4 into any of the three equations, we get:

y = (2/3)(27/4) - 2/3 = 17/4

Therefore, the orthocenter of ▲ABC is the point (27/4, 17/4).

Using compounding we know that after 30 years, the account balance has changed by $345.31.

Theoretically, continually compounded interest indicates that interest is continuously earned on an account balance as well as reinvested into the balance so that additional interest is generated.

So, a business owner put $7,000 into a Treasury bond paying a semiannual compound interest rate of 4.3%.

The bond's value after 30 years is $25,084.20.

Instead of compounding twice a year, the investment made by the business owner was made continuously.

After 30 years, we must determine the difference in the account balance.

Think of the continuously compounding recipe:

A = Pe∧rt

We have, p = 7000.

r = 4.3% = 0.043

t = 30

Then,

A = 7000e∧(0.043*30) = 25429..51

The second year's interest rate is 1.80%.

Compound interest is defined as Since compound interest accrues and is added to the accrued interest from earlier periods, borrowers are expected to pay interest on interest in addition to principal.

We are aware that the compound interest formula is,

A = P(1 + r/100)ⁿ.

Where A is the amount, P is the principle, r is the rate, and n is the number of years.

Given, Katy places $2000 over a three-year period in a savings account.

For the first year, the account offers compound interest at a 2.5% annual rate.

∴ A = 2000(1 + 2.5/100)¹.

A = 2000(1.025). (1.025).

A = 2050.

It now earns x% for the second year.

∴ 2050(1+x/100)² = 2124.46

(1+x/100)² =2124.46/2050

1+x/100 =√(2124.46/2050)

x/100 = √(2124.46/2050) -1

x = (√(2124.46/2050) -1)*100

c) The probability that the basketball player makes at least 90 of these attempts is approximately is 0.0062.

d) If the basketball player instead attempts only 10 free throws, the probability that he makes at most 4 of these is 0.0064.

As per the question given,  

a) The mean of X is given by the formula: mean = n * p, where n is the number of trials and p is the probability of success on each trial. In this case, the player attempts 100 free throws with a probability of success of 0.8, so the mean is:

mean = 100 * 0.8 = 80

Therefore, the correct answer is 80.

b) The standard deviation of X is given by the formula: standard deviation = sqrt(n * p * (1 - p)). Substituting the values, we get:

standard deviation = sqrt(100 * 0.8 * 0.2) = 4

Therefore, the correct answer is 4.

c) To find the probability that the player makes at least 90 free throws, we can use the normal approximation to the binomial distribution. The mean is 80 and the standard deviation is 4, so we can standardize the value of X as follows:

z = (90 - 80) / 4 = 2.5

Using a standard normal distribution table, we can find the probability that Z is greater than 2.5, which is approximately 0.0062.

Therefore, the correct answer is 0.0062.

d) If the player attempts only 10 free throws, the number of successful attempts X follows a binomial distribution with n=10 and p=0.8. The probability that he makes at most 4 of these attempts is:

P(X <= 4) = P(X=0) + P(X=1) + P(X=2) + P(X=3) + P(X=4)

Using the binomial distribution formula, we can calculate each of these probabilities and sum them up. Alternatively, we can use a binomial probability table or a calculator to find the cumulative probability.

Using a binomial probability calculator, we get:

P(X <= 4) = 0.0064 (rounded to four decimal places)

Therefore, the correct answer is 0.0064.
