The solution is Option C.

The value of the equation is y = 3∛ ( x - 2 ) + 5

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 ,

Let the equation be represented as A

Now , the value of A is

y = ∛ ( 27x - 54 ) + 5   be equation (1)

On simplifying the equation , we get

y = ∛27 ( x - 2 ) + 5

The cube root of 27 is ∛27 = 3

So , the equation will be

y = 3∛ ( x - 2 ) + 5

Therefore , the value of y is 3∛ ( x - 2 ) + 5

Hence , the equation is y = 3∛ ( x - 2 ) + 5

Answer: A positive correlation

Step-by-step explanation:

Correlation tells the relation between two variables.

As we know that the amount of weight you gain depends upon the number of calories you eat.

That means the amount of weight is directly proportional to the number of calories you eat ( if not burn by exercise).

That means there is a positive correlation.

So, the correct answer is " a positive correlation."

Answer:

0.58 = 58% probability she passes both courses

Step-by-step explanation:

We have two events, A and B.

[tex]P(A \cup B) = P(A) + P(B) - P(A \cap B)[/tex]

In which:

[tex]P(A \cup B)[/tex] is the probability of at least one of these events happening.

P(A) is the probability of A happening.

P(B) is the probability of B happening.

[tex]P(A \cap B)[/tex] is the probability of both happening.

In this question:

Event A: Passes the first course.

Event B: Passes the second course.

The probability she passes the first course is 0.7.

This means that [tex]P(A) = 0.7[/tex]

The probability she passes the second course is 0.67.

This means that [tex]P(B) = 0.67[/tex]

The probability she passes at least one of the courses is 0.79.

This means that [tex]P(A \cup B) = 0.79[/tex]

What is the probability she passes both courses

[tex]P(A \cup B) = P(A) + P(B) - P(A \cap B)[/tex]

[tex]0.79 = 0.70 + 0.67 - P(A \cap B)[/tex]

[tex]P(A \cap B) = 0.58[/tex]

0.58 = 58% probability she passes both courses

Step-by-step explanation:

If they have the same shape, the red graph is a translation of the blue, which is given to be y=x^2.

Since the red graph stays on the y axis at two units above the blue (y=x^2) curve, therefore the red curve is given by y=x^2+2.

The equation of the red graph is f(x) = x² + 2.

Option B is the correct answer.

An equation contains one or more terms with variables connected by an equal sign.

Example:

2x + 4y = 9 is an equation.

2x = 8 is an equation.

We have,

The graphs of f(x) = x² and f(x) = x² + 2 are both quadratic functions, which means they have a parabolic shape.

The graph of f(x) = x^2 is an upward-opening parabola with its vertex at the origin (0,0).

The parabola is symmetric about the y-axis and the x-axis.

The graph of f(x) = x² + 2 is also an upward-opening parabola, but it has been shifted upward by 2 units compared to the graph of f(x) = x².

This means that the vertex of the parabola has been shifted from (0,0) to (0,2).

Thus,

The equation of the red graph is f(x) = x² + 2.

Step-by-step explanation:

The sample mean is:

(714+751+664+789+818+779+698+836+753+834+693+802) / 12

≈ 760.9

At 0.01 significance level and 11 degrees of freedom, the critical value is t = 3.106.

The standard error is 58.3 / √12 = 16.8.

The confidence interval is:

760.9 ± 3.106 × 16.8

(708.6, 813.2)

678 is outside of the confidence interval, so we can conclude with 99% confidence that the sample does not come from a population with a mean of 678.

To test the claim that the sample FICO scores come from a population with a mean equal to 678, we can use a one-sample t-test.

A t-test is a statistical test used to determine if there is a significant difference between the means of two groups.

It is often used when the sample size is small or when the population standard deviation is unknown.

To test the claim that the sample FICO scores come from a population with a mean equal to 678, we can use a one-sample t-test.

First, we need to calculate the t-value using the following formula:

t = (x - μ) / (s / sqrt(n))

We are given that x = 678, μ = 678, s = 58.3, and n = 12. Substituting these values into the formula, we get:

t = (678 - 678) / (58.3 / sqrt(12))

t = 0

Next, we need to find the critical t-value using a t-distribution table or calculator with 11 degrees of freedom (df = n - 1) and a 0.01 significance level. The critical t-value is 3.106.

Since the calculated t-value of 0 is less than the critical t-value of 3.106, we fail to reject the null hypothesis that the sample FICO scores come from a population with a mean equal to 678.

Thus, in other words, there is not enough evidence to support the claim that the sample FICO scores have a different mean than the population mean of 678.

a(15)= -7+(15-1)9

a(15)= -7+126

Answer:

Step-by-step explanation:

The z-score corresponding to a given area of a distribution, is the number of standard deviations that the values in that area have/are from the mean.

In this case, we have a STANDARD normal distribution. In a standard normal distribution, the mean is 0 and the standard deviation is 1.

The Z-score corresponding to a given area, say the 30th percentile is

X = 0 + (-0.524)(1)

Hence, the X (number of values in the given percentile - in this case, 30th) is same as the z-table or z-calculator value for the 30th percentile in ANY normal distribution.

Answer:

We conclude that the students that took the Kaplan tutoring have a mean score greater than 29.5.

Step-by-step explanation:

We are given that the Kaplan tutoring company obtains a sample of 40 students with a mean MCAT score of 32.2 with a standard deviation of 4.2.

Let [tex]\mu[/tex] = population mean score

So, Null Hypothesis, [tex]H_0[/tex] : [tex]\mu \leq[/tex] 29.5      {means that the students that took the Kaplan tutoring have a mean score less than or equal to 29.5}

Alternate Hypothesis, [tex]H_A[/tex] : [tex]\mu[/tex] > 29.5      {means that the students that took the Kaplan tutoring have a mean score greater than 29.5}

The test statistics that will be used here is One-sample t-test statistics because we don't know about population standard deviation;

                               T.S.  =  [tex]\frac{\bar X-\mu}{\frac{s}{\sqrt{n} } }[/tex]  ~ [tex]t_n_-_1[/tex]

where, [tex]\bar X[/tex] = sample mean MCAT score = 32.2

            s = sample standard deviation = 4.2

            n = sample of students = 40

So, the test statistics =  [tex]\frac{32.2-29.5}{\frac{4.2}{\sqrt{40} } }[/tex]  ~  [tex]t_3_9[/tex]

                                    =  4.066

The value of t-test statistics is 4.066.

Now, at 0.05 level of significance, the t table gives a critical value of 1.685 at 39 degrees of freedom for the right-tailed test.

Since the value of our test statistics is more than the critical value of t as 4.066 > 1.685, so we have sufficient evidence to reject our null hypothesis as it will fall in the rejection region.

Therefore, we conclude that the students that took the Kaplan tutoring have a mean score greater than 29.5.

Answer:

485.24 miles per hour

Step-by-step explanation:

The required average speed of the flight is 485.25 miles per hour.

Given that,
Key west, Florida to Seattle, Washington is 3,518 miles. If it takes 7 hours and 15 minutes to fly there, what is the average speed is to be determined?

The average of the values is the ratio of the total sum of values to the number of values.

Speed is defined as when an object is subjected to move, the distance covered by the object in a certain time interval is the speed of that object.

Total distance to fly = 3,518 miles
Total time = 7 hours 15 minutes = 7 + 15/60
                                                    = 7.25 hour

Speed = distance / time
           = 3, 518 / 7.25
           = 485.25 miles / hours,

Thus, the required average speed of the flight is 485.25 miles per hour.
