Step-by-step explanation:

Your picture only shows one number line that isn't correct.

The number line that is correct has a filled in dot and is pointing to the left.

The dot is filled in because the inequality is less than or equal to

Since it is less than, the arrow points to the left

Answer:

Well you only have one number line but I can tell you that if x is less than or equal to 0 then it will be a closed filled in dot that is on the number 0 and is going left because x is less than or equal to 0.

Answer:

30

Step-by-step explanation:

A player answers x correct questions and y incorrect questions for a total of 40 questions.

x + y = 40

The score is obtained by subtracting y incorrect answers from two times the x of correct answers.  The player's score is 50.

2x - y = 50

Use substitution to solve.  Rearrange the first equation so that it is equal to y.  Then, substitute the y-value into the second equation.

x + y = 40

y = 40 - x

2x - y = 50

2x - (40 - x) = 50

2x - 40 + x = 50

3x - 40 = 50

3x = 90

x = 30

Since x was made to represent correct answers, the player had 30 correct answers.

Answer:

32 dances

Step-by-step explanation:

4 weeks in a month, 4 dances a week equals 16

16 time 2 equals 32

We can conclude that the students did not have any time left to work on homework.

The duration of Mr. K's math class is 1 and 1/4 hours, or 5/4 hours.

We need to determine how much time is left for the kids to do their assignment after working on problems on the board for 55 minutes and 11/12 hours. To achieve this, we must take the time spent solving issues out of the overall class time:

Total class time = 5/4 hours

Time spent on working problems = 55 minutes + 11/12 hours

= (55/60) hours + (11/12) hours

= (11/12 + 55/60) hours

= (11/12 + 11/12) hours

= (22/12) hours

= (11/6) hours

Overall class time minus the amount of time spent solving problems equals the amount of time remaining for homework.

= 5/4 hours - 11/6 hours

= (15/12) hours - (22/12) hours

= (-7/12) hours

We can infer that the kids ran out of time to finish their homework because the response is illogical because we cannot have negative time.

Step-by-step explanation:

Hello!

We can use the Elimination Method to solve the system.

To eliminate, we want atleast one variable to have the same coefficients on both equations. To do that, we can multiply the first equation by 3 to get -3y.

Now, we can vertically subtract them to eliminate -3y.

Solve for x

The value of x is 3.

To solve for y, we can plug in 3 into the original first equation and solve for y.

Solve for y

The value of y is -4.

The solution to the system is (3,-4).

a. Hence in first case, if the distribution is normal, Probability is 0.0077 that the sample mean hardness for a random sample of 16 pins is at least 51

b. In second, Probability is 0 that the sample mean hardness for a random sample of 44 pins is at least 51.

The mean is one of the measures of central tendency used in statistics. The average of the specified collection of numbers is what is referred to as mean. It indicates the data set's values that are distributed equally. The three most popular methods for determining central tendency are the mean, median, and mode.

To find the mean, tally up all the values listed on a datasheet, then divide that total by the total number of values. When all the values are organized in ascending order, the median is the value that falls in the middle of the data. The number in the list that is repeated a maximum number of times is the mode.

Y ~ N ( µ = 50 and σ = 1.6 )

P ( Y > 51 ) = 1 - P ( Y < 51 )

Standardizing the  value

Z = ( Y - µ ) /( σ / √(n))

Z = ( 51 - 50 ) /( 1.6 / √ ( 15 ) )

Z = 2.4206

P (  ( Y - µ ) /( σ / √ (n)) > ( 51 - 50 ) /( 1.6 / √(15) )

P ( Z > 2.42 )

P ( Y > 51 )  = 1 - P( Z < 2.42 )

P ( Y  > 51 )  = 1 - 0.9923  ( from the Z table)

P ( Y   > 51 )  = 0.0077

b)

P ( Y > 51 )  =1 - P ( Y < 51 )

Standardizing the  value

Z = ( Y - µ ) /( σ / √(n))

Z = ( 51 - 50 ) /( 1.6 / √ ( 43 ) )

Z = 4.1

P (  ( Y - µ ) /( σ / √ (n)) > ( 51 - 50 ) / ( 1.6 / √(43) )

P ( Z > 4.1 )

P ( Y > 51 )  =1 - P ( Z < 4.1 )

P ( Y > 51 )  = 1 - 1

Given the following data: n = 220, x = 29.9 hg, s = 7.3 hg, confidence level = 98%.To find the confidence interval estimate of the mean at a 98% confidence level, we use the following formula: CI = x ± Zα/2 * σ/√n Where Zα/2 is the Z-value for the 98% confidence level and is calculated as follows:

Zα/2 = 1 - (α/2)Zα/2 = 1 - (0.98/2)Zα/2 = 1 - 0.49Zα/2 = 0.51From the above formula and calculation, we can find the confidence interval for μ as follows: CI = 29.9 ± 0.51(7.3/√220)CI = 29.9 ± 0.97CI = (28.93, 30.87)This indicates that we are 98% confident that the true mean weight of newborn girls falls between 28.93 hg and 30.87 hg.Next, we need to compare these results with a confidence interval estimate from a different sample set which has only 16 sample values. From this sample set, we have: x = 29.7 hg, s = 3.1 hg. Using a 98% confidence level, we have the following: CI = x ± Zα/2 * σ/√nWhere n = 16, Zα/2 = 0.51 (from above), Comparing the two confidence intervals, we see that they do overlap quite a bit, but they are not identical. The first confidence interval (from the larger sample) is (28.93, 30.87) while the second confidence interval (from the smaller sample) is (29.31, 30.09).

The shot put is in the air for approximately 3 seconds.

The height h (in feet) of the shot put as a function of the time t (in seconds) after it is thrown can be modeled by the equation:

h(t) = h + vt - (1/2)gt²

where v is the initial vertical velocity in feet per second, and s is the initial height in feet.

Here, the initial vertical velocity is 40 feet per second, and the initial height is 5.69 feet. Therefore, we can plug in these values to get:

h = -16t² + 40t + 5.69

To find the time that the shot put is in the air, we need to find the value of t when h = 0, since the shot put will hit the ground when its height is 0.

Therefore, we can set the equation equal to 0 and solve for t:

0 = -16t² + 40t + 5.69

Using the quadratic formula, we get:

t = (-b ± √(b² - 4ac)) / 2a

where a = -16, b = 40, and c = 5.69.

Plugging in these values, we get:

t = (-40 ± √(40² - 4(-16)(5.69))) / 2(-16)

Simplifying, we get:

t ≈ 3 or t ≈ 0.2

Since the shot put cannot be in the air for negative time, the only possible answer is t ≈ 3.

Therefore, the shot put is in the air for approximately 3 seconds.

The source of error variance that does not affect test-retest reliability but would affect the reliability of a parallel forms test is called time sampling error.

Error variance is a term used to describe the variability in test scores that is not caused by the trait or ability being measured. Test-retest reliability is a measure of consistency over time. This type of reliability can be determined by measuring the same trait or ability in the same group of people on two separate occasions. If the measure is reliable, then the scores on the first and second occasions should be similar. Parallel forms reliability is a measure of consistency between two different tests that are designed to measure the same trait or ability. If the two tests are highly correlated, then they can be considered to be parallel forms. Error variance due to time sampling refers to the variability in test scores that is caused by the fact that people's scores can vary from one test administration to the next due to factors that are unrelated to the trait or ability being measured. Since this type of error is related to the passage of time, it would have an effect on the reliability of a parallel forms test but not on the reliability of a test-retest.

The equation for the line that is parallel to the given line and goes through the point (-8 2), is y = 3x + 26. See the explanation below.

Recall that the equation for the line is always given as:

y = mx + b

Where m is the slope.

Assuming that you have a line  y = 3x + 2

The line parallel to this line but intersecting the point (-8,2) is found by using y = mx + b and solving for b

m = 3; x = -8; and y = 2

b = y - mx

b = (2) - (3) (-8)

b = 26

Five other iterated integrals that are equal to the given iterated integral are:

∫₀⁷ ∫y²₂ ∫₀ʸ f(x, y, z) dx dz dy

∫₀⁷ ∫₀ʸ ∫y²₂ f(x, y, z) dx dz dy

∫y²₂ ∫₀⁷ ∫₀ʸ f(x, y, z) dx dy dz

∫y²₂ ∫₀ʸ ∫₀⁷ f(x, y, z) dx dy dz

∫₀ʸ ∫y²₂ ∫₀⁷ f(x, y, z) dz dx dy

To find the five other iterated integrals that are equal to the given iterated integral, we need to rearrange the order of integration. We can do this by changing the order of the limits of integration and writing the integral with respect to a different variable first.

The original integral is:

∫₀⁷ ∫y²₂ ∫₀ʸ f(x, y, z) dz dx dy

Now, we can change the order of integration in the following ways:

∫₀⁷ ∫y²₂ ∫₀ʸ f(x, y, z) dx dz dy

∫₀⁷ ∫₀ʸ ∫y²₂ f(x, y, z) dx dz dy

∫y²₂ ∫₀⁷ ∫₀ʸ f(x, y, z) dx dy dz

∫y²₂ ∫₀ʸ ∫₀⁷ f(x, y, z) dx dy dz

∫₀ʸ ∫y²₂ ∫₀⁷ f(x, y, z) dz dx dy

Each of these integrals has the same value as the original integral, but with a different order of integration. It is important to note that changing the order of integration can sometimes make the integral easier to evaluate, especially if the integrand has certain symmetries.

The area of mathematics known as probability deals with numerical representations of the likelihood that an event will occur or that a statement is true.

The probability of an occurrence is a number between 0 and 1, with 1 representing certainty and 0 representing impossibility.

Since there are no other conceivable outcomes and the coin is fair, the odds of both the possibilities, "heads" and "tails," are equally likely to occur. As a result, the probability of either occurrence is half (which could also be written as 0.5)

a.  The elasticity of demand is E = -1.607.

b. Total revenue is maximized at q ≈ 1354.00.

The demand function is: q = 40,600 - 9p^2

a. To find the elasticity of demand, we need to differentiate the demand function with respect to p and then multiply by p/q:

dq/dp = -18p

(p/q) * (dq/dp) = (-18p/q)

Then, we can substitute p = 2000 and q = 22,400 (the values given in a previous question) into this expression:

E = (-18(2000)/22400) = -1.607

b. Total revenue is maximized where the demand is unit elastic (E = -1). We can set the expression for E equal to -1 and solve for p to find the corresponding value of q:

-1 = (-18p/q)

q = 18p

Substituting the demand function into this expression and simplifying, we get:

q = 40,600 - 9p² = 18p

Rearranging and solving for p, we get:

9p² + 18p - 40,600 = 0

Using the quadratic formula, we get:

p = (-18 ± √(18² - 4(9)(-40,600)))/(2(9)) ≈ 75.22 or -227.22

Since the price must be positive, the only valid solution is p ≈ 75.22. Substituting this back into the demand function, we get:

q ≈ 18(75.22) ≈ 1354.00
