Find the equation of a line that is parallel to the line x = -11 and contains the point (-3,9)

Mathematics

Arisa [49]3 years ago

Answer:

x = -3

Step-by-step explanation:

the lines in the form:

y = a , where a is a constant is a horizontal line

and

x = b, where b is a constant is a vertical line

To find lines that are parallel to the horizontal and vertical lines with point given (n,p), we follow the rule below:

1. If we have a line y = a and goes through point (n,p), the parallel line will have equation y = p

2. If we have a line x = b and goes through the point (n,p), the parallel line will have equation x = n

<em><u>Now, this question gives a vertical line x = -11 and we need to find line parallel to this that goes through (-3,9). So, from RULE #2 above, we can say the parallel line's equation would be:</u></em>

x = -3

Which of the following will make a confidence interval narrower and more precise?
swat32

Answer:

B. Larger sample size and lower confidence level

Step-by-step explanation:

The margin of error of a confidence interval is given by the following formula:

M = z*\frac{\sigma}{\sqrt{n}}

In which \sigma is the standard deviation of the population and n is the size of the sample.

z is related to the confidence level. The higher the confidence level, the higher the value of Z.

So, the margin of error is direct proportion to the confidence level and inverse proportional to the sample size.

We want to decrease the margin of error.

So the correct answer is:

B. Larger sample size and lower confidence level

The combined math and verbal scores for students taking a national standardized examination for college admission, is normally d
kipiarov [429]

Answer:

The minimum score that such a student can obtain and still qualify for admission at the college = 660.1

Step-by-step explanation:

This is a normal distribution problem, for the combined math and verbal scores for students taking a national standardized examination for college admission, the

Mean = μ = 560

Standard deviation = σ = 260

A college requires a student to be in the top 35 % of students taking this test, what is the minimum score that such a student can obtain and still qualify for admission at the college?

Let the minimum score that such a student can obtain and still qualify for admission at the college be x' and its z-score be z'.

P(x > x') = P(z > z') = 35% = 0.35

P(z > z') = 1 - P(z ≤ z') = 0.35

P(z ≤ z') = 1 - 0.35 = 0.65

Using the normal distribution table,

z' = 0.385

we then convert this z-score back to a combined math and verbal scores.

The z-score for any value is the value minus the mean then divided by the standard deviation.

z' = (x' - μ)/σ

0.385 = (x' - 560)/260

x' = (0.385×260) + 560 = 660.1

Hope this Helps!!!

A sphere has a volume of approximately 113 cubic units. Which of the following best represents the radius of the sphere?
Kitty [74]

Answer:

H. 3 units

Step-by-step explanation:

In order to answer this question, we have to apply the formula for the sphere volume. The formula is:

V=\frac{4}{3} \pi r^{3}

Plugging the given number into V, we calculate that:

113 = \frac{4}{3}\pi r^{3}\\84.75 = \pi r^{3}   \\

If π=3.14, the radius is:

r ≈ 3 units.
