What is 5.2 plus 176.2

Answer:

vertical is x = - 1 , horizontal is y = 5

Step-by-step explanation:

the equation of a vertical line is

x = c ( c is the value of the x- coordinates the line passes through )

the line passes through (- 1, 5 ) with x- coordinate - 1 , then

x = - 1 ← equation of vertical line

the equation of a horizontal line is

y = c ( c is the value of the y- coordinates the line passes through )

the line passes through (- 1, 5 ) with y- coordinate 5 , then

y = 5 ← equation of horizontal line

The measure of center that best represents the data is mean and its values for José and Manuel are 20.1 and 21.8, respectively. Comparing the mean values, José generally scores less goals in a game than Manuel.

To find the measure of center that best represents the data, we will use the mean.

The measure is calculated by adding up all the values and dividing by the total number of values.

The mean number of goals for José is:

= (7+12+17+4+18+25+38+32+37+11)/10

= 20.1

The mean number of goals for Manuel is:

= (17+23+21+31+30+5+26+37+19+9)/10

= 21.8.

Answer:

It is not possible to determine the local maximum of the graphed function over the interval [-3, 1.5] based on the given information. The maximum value of the curved line occurs at (negative 1.6, 56) and (2, 0), but these points do not fall within the interval [-3, 1.5]. Similarly, the minimum value of the curved line occurs at (0.8, negative 11.4), but this point also does not fall within the interval [-3, 1.5]. The curve crosses the x-axis and y-axis at (negative 2.5, 0), (0, 0), and (2, 0), but these points do not correspond to local maxima or minima of the curve.

To determine the local maximum over the interval [-3, 1.5], it would be necessary to have additional information about the shape of the curve and its values at points within the given interval.

Step-by-step explanation:

The company's claim can be evaluated using a hypothesis test. The null hypothesis, denoted as H0, assumes that the true proportion of chips that do not fail in the first 1000 hours is 55% or lower.

Ha stands for the alternative hypothesis, which assumes that the real proportion is higher than 55%. This test has a significance level of 0.01.

A sample of 800 chips was taken based on the information provided, and it was discovered that 60% of them do not fail in the first 1000 hours. A one-sample percentage test can be used to verify the assertion.  The test statistic for this test is the z-score, which is calculated as:

\(\[ z = \frac{{p - p_0}}{{\sqrt{\frac{{p_0(1-p_0)}}{n}}}} \]\)

If n is the sample size, p0 is the null hypothesis' assumed proportion, and p is the sample proportion.

If we substitute the values, we get:

\(\[ z = \frac{{0.6 - 0.55}}{{\sqrt{\frac{{0.55(1-0.55)}}{800}}}} \]\)

The z-score for this assertion is calculated, and we find that it is approximately 2.86.

In order to determine whether there is sufficient data to support the company's claim, we compare the computed z-score with the essential value. At a significance level of 0.01 the critical value for a one-tailed test is approximately 2.33.

Because the estimated z-score (2.86) is larger than the determining value (2.33), we reject the null hypothesis. Therefore, the company's assertion that more than 55% of the chips do not fail in the first 1000 hours of use is supported by sufficient data at the 0.01 level.

The sum of the angle measures of the polygon is 540°, the value of x is 5.

The sum of the angle measures of the polygon is 540°.

We know that the sum of the interior angles of a polygon of n sides = (n – 2) × 180°. = 3× 180°= 540°

If a polygon has x sides, then the sum of its angle measures can be found using the formula:

Therefore, for a polygon with x sides, the equation becomes:

⇒(x-2) * 180° = 540°

Solving for x, we get:

⇒x = (540° + 360°) / 180° + 2

⇒x = 3 + 2

⇒x = 5

So, the polygon has 5 sides.

Therefore, the value of  x is 5.

The answer to this is A

If the best fit line is nearly horizontal, it suggests no significant relationship between height and head circumference.

In this scenario, the explanatory variable is the child's height, as it is being used to predict the head circumference.

The response variable is the head circumference itself, as it is the variable being predicted or explained by the height.

To draw a scatter diagram of the data, you would plot the child's height on the x-axis and the corresponding head circumference on the y-axis. Each data point would represent a child's measurement pair.

Once all the data points are plotted, you can then draw the best fit line, also known as the regression line, that represents the overall trend or relationship between height and head circumference.

By observing the scatter diagram and the best fit line, you can determine the relationship between a child's height and head circumference.

If the best fit line has a positive slope, it indicates a positive relationship, meaning that as height increases, head circumference tends to increase as well.

If the best fit line has a negative slope, it indicates a negative relationship, meaning that as height increases, head circumference tends to decrease.

By assessing the slope of the best fit line in the scatter diagram, you can determine whether the relationship between height and head circumference is positive, negative, or nonexistent.

The number of miles that the truck drove is 550 miles.

From the information, Xin must pay the driver $20 per hour of driving and also has an expense of $2.25 per mile. This can be illustrated as:

20x + 2.25y = 1457.50 ....... i

x = number of hours

y = number of miles driven

The driver drove an average of 50 miles per hour. This will be illustrated as:

y/x = 50

y = 50x

Substitute into equation i

20x + 2.25y = 1457.50

20x + 2.25(50x) = 1457.50

20x + 112.50x = 1457.50

Collect like terms

132.50x = 1457.50

Angle F is 50° because their side lengths are different but the angle measurements did not change. All triangles add up to 180 degrees and a right angle is 90 and it gives you the other angle measurement. So you would do 40 plus 90 which would get you 130. To find the last angle you would do 180 minus 130 which is 50. Angle F is 50 degrees.

Aryabhata, also called Aryabhata I or Aryabhata the Elder, (born 476, possibly Ashmaka or Kusumapura, India), astronomer and the earliest Indian mathematician whose work and history are available to modern scholars. He is also known as Aryabhata I or Aryabhata the Elder to distinguish him from a 10th-century Indian mathematician of the same name. He flourished in Kusumapura—near Patalipurta (Patna), then the capital of the Gupta dynasty—where he composed at least two works, Aryabhatiya (c. 499) and the now lost Aryabhatasiddhanta.

Aryabhatasiddhanta circulated mainly in the northwest of India and, through the Sāsānian dynasty (224–651) of Iran, had a profound influence on the development of Islamic astronomy. Its contents are preserved to some extent in the works of Varahamihira (flourished c. 550), Bhaskara I (flourished c. 629), Brahmagupta (598–c. 665), and others. It is one of the earliest astronomical works to assign the start of each day to midnight.

Aryabhatiya was particularly popular in South India, where numerous mathematicians over the ensuing millennium wrote commentaries. The work was written in verse couplets and deals with mathematics and astronomy. Following an introduction that contains astronomical tables and Aryabhata’s system of phonemic number notation in which numbers are represented by a consonant-vowel monosyllable, the work is divided into three sections: Ganita (“Mathematics”), Kala-kriya (“Time Calculations”), and Gola (“Sphere”).

Hope this helps!

The correct answer are as follows

a) True, b) False, c) False, d) False, e) False

(a) True. The standard deviation is always a non-negative value since it is a measure of the spread or variability of the data set.
(b) False. Since A and B are disjoint, they have no overlapping outcomes, which means P(A AND B) = 0.
(c) False. Although the mean and median are often close in a normal distribution, they are not always equal. The median is the middle value of the distribution, while the mean is the average of all values.
(d) False. A 95% confidence interval is narrower than a 98% confidence interval of the same parameter since it requires a higher level of confidence to have a wider interval.
(e) False. If the value of the test statistic is 1.5 and P(T<1.5)=0.98, then the p-value is 0.02. Since the p-value is less than the level of significance of 0.05, we reject the null hypothesis.
(a) True. The standard deviation of a data set cannot be negative because it is a measure of dispersion and is calculated as the square root of the variance, which is always non-negative.

(b) False. If A and B are disjoint, then P(A AND B) = 0, since disjoint events cannot occur simultaneously.

(c) True. For a normal distribution, the mean is always equal to the median, indicating a symmetrical distribution.

(d) False. A 95% confidence interval is narrower than a 98% confidence interval of the same parameter because a higher confidence level requires a wider interval to capture the true value with greater certainty.

(e) True. In a two-tailed test, if the test statistic follows a Student's t-distribution with P(T<1.5)=0.98, this means that P(T>1.5)=0.02. For a two-tailed test at a 0.05 level of significance, the rejection regions are in both tails, with 0.025 in each tail. Since P(T>1.5)=0.02 < 0.025, we fail to reject the null hypothesis.

Step-by-step explanation:

Answer:

Step-by-step explanation:

When putting i to a power, there is a rule.

i¹ = i

i² = -1

i³ = -i

i⁴ = 1

And it repeats again, such as:

i⁵ = i

i⁶ = -1

And so forth.

This rule also applies to -i, but the values are slightly different:

(-i)¹ = -i

(-i)² = -1

(-i)³ = i

(-i)⁴ = 1

And that one keeps repeating such as

(-i)⁵ = -i

(-i)⁶ = -1

And so forth.

So to answer your question, (-i)³ = i.

1. The limit does not exist if sin^2(θ) is nonzero. 2. The limit is 0 if sin^2(θ) = 0.

To find the limit as (x, y) approaches (0, 0) of the expression:

f(x, y) = (x^2 + y^2)/(xy^2)

We can use polar coordinates substitution. Let x = rcos(θ) and y = rsin(θ), where r > 0 and θ is the angle.

Substituting these values into the expression:

f(r, θ) = ((rcos(θ))^2 + (rsin(θ))^2)/(r(s^2)(sin(θ))^2)

        = (r^2cos^2(θ) + r^2sin^2(θ))/(r^3sin^2(θ))

        = (r^2(cos^2(θ) + sin^2(θ)))/(r^3sin^2(θ))

        = r^2/(r^3sin^2(θ))

Now, we can evaluate the limit as r approaches 0:

lim(r→0) (r^2/(r^3sin^2(θ)))

Since r approaches 0, the numerator approaches 0, and the denominator approaches 0 as well. However, the behavior of the limit depends on the angle θ.

If sin^2(θ) is nonzero, then the limit does not exist because the expression oscillates between positive and negative values as r approaches 0.

If sin^2(θ) = 0, then the limit is 0, as the expression simplifies to 0/0.

Therefore, the answer is:

1. The limit does not exist if sin^2(θ) is nonzero.

2. The limit is 0 if sin^2(θ) = 0.
