We want to find the probability that the sample mean cholesterol value falls within certain ranges. Specifically, we want to find the probability that the sample mean cholesterol value is between 145 and 165 (part a) and between 140 and 170 (part b).

The probability that the sample mean cholesterol value is between 145 and 165 can be found using the central limit theorem (CLT). Since the sample size is large (n = 16), the sample mean cholesterol value will be approximately normally distributed, regardless of the underlying population distribution. We can assume that the sample mean cholesterol value follows a normal distribution with mean μ and standard deviation σ/sqrt(n), where μ is the population mean cholesterol value and σ is the population standard deviation.

Using this assumption, we can calculate the z-score for each end of the interval:

z1 = (145 - μ) / (σ / sqrt(n))

z2 = (165 - μ) / (σ / sqrt(n))

Then, we can use a standard normal distribution table or a calculator to find the probability that the sample mean cholesterol value falls between these z-scores:

P(145 < x^- < 165) = P(z1 < Z < z2)

where Z is a standard normal random variable.

Similarly, to find the probability that the sample mean cholesterol value is between 140 and 170 (part b), we can calculate the corresponding z-scores and use the same formula.

In both cases, the assumption of normality may not be appropriate if the population distribution is strongly skewed or has heavy tails. In such cases, non-parametric methods or bootstrapping may be more appropriate.

1) The statement of Lin is correct.

2) (a) When scale factor, k = 9, area of the new triangle = 8100 square inches

(b) When k = 3/4, area of the new triangle = 56.25 square inches.

Given that,

A triangle has area 100 square inches.

It's dilated by a factor of k = 0.25.

When the triangle is dilated by a scale factor of k, then, each of the base and height is dilated by the scale factor of k.

So new area of the triangle after the dilation with the original triangle having base = b and height = h is,

Area of new triangle = 1/2 (kb)(kh) = k² (1/2 bh) = k² × Area of original triangle

Here original area = 100 square inches.

k = 0.25

New area = (0.25)² 100 = 6.25 square inches

So the correct statement is that of Lin.

Mai may found the new area by just multiplying the scale factor with 100, instead of taking the square of the scale factor. That is why she got 25 square inches as the new area.

2) (a) When k = 9,

Area of the new triangle = 9² (100) = 8100 square inches

(b) When k = 3/4

Area of the new triangle = (3/4)² (100) = 56.25 square inches

Hence the areas are found.

Answer: (-5,8)

Step-by-step explanation:

X: 1 + (-6) = -5

Y: 2+6 = 8

Answer: x = 1, y = 1

Step-by-step explanation:

Step 1: Solve for x

Multiply bottom equation by 2.

5x + 2y = 7

2(3x – y = 2)

___________

5x + 2y = 7

+ 6x - 2y = 4

___________

11x =  11    divide each side by 11      x = 1

Step 2: Solve for y

Substitute x=1 into any equation. We will do equation 1.

5x + 2y =  7    5*1 + 2y = 7

5 + 2y = 7  

subtract 5 from each side.

2y = 2  divide each side by 2

y = 1

The number of zip codes that have at least one occurrence of the digit 0 and at least one digit greater than or equal to 5 is X.

The number of zip codes that satisfy the given conditions, we can analyze each digit's possibilities.

For a zip code to have at least one occurrence of the digit 0, there are no restrictions. Each of the five digits can independently take any value from 0 to 9, resulting in 10 possibilities for each digit.

For a zip code to have at least one digit greater than or equal to 5, we need to consider the complementary case where all digits are less than 5 and subtract it from the total number of possibilities.

In this complementary case, each digit can only take values from 0 to 4, resulting in five possibilities for each digit.

Therefore, the total number of zip codes that have at least one occurrence of the digit 0 and at least one digit greater than or equal to 5 is:

Total number of possibilities - Number of zip codes with all digits less than 5

= 10^5 - 5^5

= 100,000 - 3,125

= 96,875

Therefore, there are 96,875 zip codes that satisfy the given conditions.

For your second question, the largest thing in the world is Asia. The largest of the seven continents and outmatched when coming to population. If you are talking about a living creature, undoubtedly the blue whale would come out in first weighing in at 150 tons and 33 meters long.

For the largest number, that's a tricky one. There is no limit to the amount of numbers one could come up with, as you can always add 1 digit anywhere inside of a number and it becomes bigger. This is where infinity comes in.

Infinity is a concept, meaning it isn't a real number, however we do use it in the math world a lot. infinity is the thought that there is no end, for example pi is an infinite number (meaning there is an endless amount of digits.) if you hit 9 on a keyboard and held it forever, you still wouldn't reach the biggest number in existence, because you can always add another 9.

The band will march 3.2 kilometers at the same rate.

The ratio is the division of the two numbers.

For example, a/b, where a will be the numerator and b will be the denominator.

Proportion is the relation of a variable with another. It could be direct or inverse.

Given that,

800 meters for every 15 minutes

800 meters  ⇔ 15 minutes

Multiply 4 by both sides

3200 meters ⇔ 60 minutes

Now,

60 minutes = 1 hour

And,

Since 1000 meter = 1 kilometer ⇒ 3200 meter = 3.2 kilometer.

So,

1 hour ⇔ 3.2-kilometer.

Answer: 5

Step-by-step explanation:

The system of equations that matches the given graph is:

A. 3x - 6y = 12

9x - 18y = 36

To determine which system of equations matches a given graph, we need to analyze the slope and intercepts of the lines in the graph.

Looking at the options provided:

A. 3x - 6y = 12

9x - 18y = 36

B. 3x + 6y = 12

9x + 18y = 36

Let's analyze the equations in each option:

For option A:

The first equation, 3x - 6y = 12, can be rearranged to slope-intercept form: y = (1/2)x - 2.

The second equation, 9x - 18y = 36, can be simplified to 3x - 6y = 12, which is the same as the first equation.

In option A, both equations represent the same line, as they are equivalent. Therefore, option A does not match the given graph.

For option B:

The first equation, 3x + 6y = 12, can be rearranged to slope-intercept form: y = (-1/2)x + 2.

The second equation, 9x + 18y = 36, can be simplified to 3x + 6y = 12, which is the same as the first equation.

In option B, both equations also represent the same line, as they are equivalent. Therefore, option B does not match the given graph.

We conclude that the conjecture that the quotient of a number and its reciprocal is always equal to 1 is not correct.

Conjecture: The quotient of a number and its reciprocal is always equal to 1.

To test this conjecture, let's consider a specific number, x, and its reciprocal, 1/x.

According to the conjecture, the quotient of x and its reciprocal should be 1.

Let's perform the calculation:

\(x / (1/x) = x * x/1 = x^2\)

Based on the calculation, we see that the quotient of x and its reciprocal simplifies to x^2, not necessarily equal to 1. Therefore, the conjecture is not true in general.

The value of the test statistic is -1.5.

Test statistic:

A test statistic is a statistic used in statistical hypothesis testing. A hypothesis test is typically specified in terms of a test statistic, considered as a numerical summary of a data set that reduces the data to one value that can be used to perform the hypothesis test.

The formula for test statistic:

Test statistic = z = \(\frac{P - P_{0} }{\sqrt{\frac{P_{0( 1 -P_{0} } }{n} } }\)

A sample of patients n = 150

Patients insured =x = 75

P = x/n

  = 75/ 150

  = 1/2

  = 0.5

\(P_{0}\) = 56/100

    = 0.56

Putting the values we get:

z = \(\frac{0.5 - 0.56}{\sqrt{\frac{0.56( 1- 0.56)}{150} } }\)

  = \(\frac{-0.06}{\sqrt{0.00164} }\)
