The possible line of best fit is given by y = -0.5x + 10

A linear equation is in the form:

y = mx + b

Where y, x are variables, m is the rate of change and b is the y intercept.

Let y represent the students still participating in the final round while x represent the number of spelling words attempted.

Since the line of best fit has a negative, linear association, this means that the slope is negative. A possible linear function is:

y = -0.5x + 10

The possible line of best fit is given by y = -0.5x + 10

a. The value of c in the probability mass function when x is a discrete random variable is 0.15

b. The value of P(x > 3)  is 0.25

c. The value of P(3 ≤ x ≤ 5) is 0.15

d.  the probability that x is less than 6 given that it is greater than or equal to 1 is approximately 0.353.

In probability mass function, sum of the probabilities for all possible values of x must be equal to 1

Thus,

0.2 + 2c + 0.2 + c + 0.1 = 1

Solve for c

c = 0.15

Hence, the probability mass function for x can be rewritten as;

x:      0     1     2   4     10

p(x): 0.2 0.3 0.2 0.15 0.1

To find P(x > 3), add the probabilities for all values of x that are greater than 3. The values greater than 3 are 4 and 10

sum of their  probabilities

P(x > 3) = P(x = 4) + P(x = 10)

= 0.15 + 0.1

= 0.25

To find P(3 ≤ x ≤ 5),sum the probabilities for all values of x between 3 and 5, inclusive:

P(3 ≤ x ≤ 5) = P(x = 4)

= 0.15

To find P(x < 6 | x ≥ 1), use the formula for conditional probability:

P(x < 6 | x ≥ 1) = P(x < 6 and x ≥ 1) / P(x ≥ 1)

To find the numerator, we sum the probabilities for all values of x between 1 and 5, inclusive

P(x < 6 and x ≥ 1) = P(x = 1) + P(x = 2) + P(x = 4)

= 0.3

To find the denominator, we sum the probabilities for all values of x greater than or equal to 1:

P(x ≥ 1) = P(x = 1) + P(x = 2) + P(x = 4) + P(x = 10)

= 0.85

Therefore, we have

P(x < 6 | x ≥ 1) = (0.3 / 0.85) ≈ 0.353

Thus, the probability that x is less than 6 given that it is greater than or equal to 1 is approximately 0.353.

Step-by-step explanation:

The sum of an infinite geometric series can be found when the absolute value of the common ratio, r, is less than 1.

\(\boxed{\begin{minipage}{5.5 cm}\underline{Sum of an infinite geometric series}\\\\$S_{\infty}=\dfrac{a}{1-r}$,\quad $|r| < 1$\\\\where:\\\phantom{ww}$\bullet$ $a$ is the first term. \\ \phantom{ww}$\bullet$ $r$ is the common ratio.\\\end{minipage}}\)

To determine which of the given infinite geometric series can be summed using the formula, calculate the value of r for each series.  To do this, divide a term by the previous term.

Given infinite geometric series:

\(\implies r=\dfrac{6}{-2}=-3\)

As r is not in the interval −1 < r < 1, the sum of the infinite series cannot be found using the formula.

Given infinite geometric series:

\(\implies r=\dfrac{12}{3}=4\)

As r is not in the interval −1 < r < 1, the sum of the infinite series cannot be found using the formula.

Given infinite geometric series:

\(\implies r=\dfrac{2}{1}=2\)

As r is not in the interval −1 < r < 1, the sum of the infinite series cannot be found using the formula.

Given infinite geometric series:

\(\implies r=\dfrac{4}{8}=\dfrac{1}{2}\)

As |r| < 1 the sum of the infinite series can be found using the formula.

Therefore, the infinite series for which the sum can be found by using the formula is:

To find the height of the cylinder when the volume is given as 1500 in³ and the radius is 7 inches, we can use the formula for the volume of a cylinder:

Volume = π * r² * h

Substituting the given values, we have:

\(1500 = 3.14 * 7^2 * h1500 = 3.14 * 49 * h1500 = 153.86 * h\)

To solve for h, we divide both sides of the equation by 153.86:

h = 1500 / 153.86

h ≈ 9.75

Rounding the answer to the nearest hundredth, the height of the cylinder is approximately 9.75 inches.

Therefore, the height of the cylinder is 9.75 inches.

Note: It is important to use the accurate value of π, which is approximately 3.14159, for precise calculations. However, in this case, since you specified to use 3.14 for π, I have used that approximation to calculate the height.

Answer:

Thus, the equation of line for point (-1, 2)  is y = x + 3.

Step-by-step explanation:

Answer:

The equation of the line is y = x + 3.

Step-by-step explanation:

A line that is parallel to y=x+4 and passes through the point (-1,2) will have the same slope as y=x+4. The slope of y=x+4 is 1, so the equation of the line will be in the form y = mx + b, where m=1. To find b, we can plug in x = -1 and y = 2 into the equation and solve for b.

y = mx + b

y = 1 * -1 + b

y = -1 + b

b = y + 1

b = 2 + 1

b = 3

Answer:

3 = x

Step-by-step explanation:

Well, the two unknown sides share the same size due to the same angle, so now, using the fact we only have the info about one side, we need to do a reverse pythagorean theorem.

\(c^{2} = a^{2} + b^{2}\)

Our a and b are the same, so I will change them to "x" and combine them.

\(c^{2} = 2(x)^{2}\)

Now we plug in our "c" and square it ("C" in this case is: \(3\sqrt{2}\) )

\(18 = 2(x)^{2}\)

\(9 = x^{2}\)

Answer:

a) ∠VUW

b) VY

c) XYV

d) 180°

e) 65°

Step-by-step explanation:

A central angle is an angle that creates an arc in a circle, while also having its vertex as the center of the circle.

Here the center is U. So, the vertex of the angle must include U.

This means that there are multiple answers to part a.

The answers can be:

∠VUW

∠WUX

∠XUV

A minor arc is any arc that doesn't exceed 180°.

The possible answers for part b, using this definition are:

WV

VY

XY

The answer you inputted here is incorrect.

The order of the letters matter.

A tip for you to never mess these up is to trace the letters you've chosen with your finger and see if that image you make with your finger matches up with the shape you wanted to make.

An arc that makes a semicircle is an arc that connects the endpoints of the diameter. The diameter in this case is VX.

This means that your answer must start with V and end with X, or the other way around. (Meaning you could start with x and end with v, but always make sure you keep the endpoints of the diameter as the endpoints of the arc.)

The possible answers for this part are either:

VYX or VWX

This arc intercepts the diameter, which is a straight line and a central angle.

The angle of a diameter is 180°.

The arc of an intercepted central angle has the same measure of the central angle itself.

So, the measure of VWX is 180°.

If an arc intercepts a central angle, then the arc has the same measure as the central angle.

This rule works the other way around, too.

So, the central angle has the same measure as the minor arc that it intercepts.

Measure of arc VUW is 65°, so m∠VUW is also 65°.

Answer:

a. (23.4%, 38.9%)

Step-by-step explanation:

Р = x/∝ = 52/167 = 0.3114

At 95% confidence level

∝ = 1 - 0.95 = 0.05

Zerit = Z0.05/2 = 1.96

Р ± Zerit \(\sqrt{P(1-P) / n}\)

= 0.3114 ± 1.96 \(\sqrt{0.3114(1-0.3114) / 167}\)

Closest Option = 23.4%, 38.9%

A 95% confidence interval for the true percentage of individuals whose favorite animal is a dog is (23.4%, 38.9%)

The formula for calculating the confidence interval based o proportion is expressed according to the formula:

\(p\pm z\sqrt{\frac{p(1-p)}{n} }\)

z is the z-score at 95% confidence interval

p is the proportion

n is the sample size

Given the following parameters

p = 52/167 = 0.31

z = 1.96

Step-by-step explanation:

given that y varies inversely as x then the equation relating them is

y = \(\frac{k}{x}\) ← k is the constant of variation

to find k use the condition y = 12 when x = 6

12 = \(\frac{k}{6}\) ← multiply both sides by 6 to clear the fraction
