Step-by-step explanation:

Answer:

x= 17.3

Step-by-step explanation:

-10(x-17) = -3                 equation

-10x + 170 = -3             multiply -10 to everything in parenthesis

-10x = -173                   subtract 170 from both sides of the equation

\(\frac{-10x}{-10} =\frac{-173}{-10}\)                  divide -10 from both sides

x= 17.3

Two angles are said to be complementary angles if their sum is 90 degrees. Then ∠I ≅ ∠H is proved, below.

The angle is the distance between the intersecting lines or surfaces. The angle is also expressed in degrees. The angle is 360 degrees for one complete spin.

Two angles are said to be complementary angles if their sum is 90 degrees.

The total amount Andrea paid for her computer is $1611.425.

A percentage is a value or ratio that may be stated as a fraction of 100. If we need to calculate a percentage of a number, we should divide it's entirety and then multiply it by 100

In this situation, Andrea ordered a computer on the Internet and the computer cost $1,499 plus 7 1/2% sales tax.

The amount that will be paid will be:

= Cost of computer + Tax

= $1499 + (7.5% × $1499)

= $1499 + $112.425

= $1611.425

The amount is $1611.425.

Answer:

a) The perimeter of a rectangle is given by the formula:

P = 2L + 2W

where P is the perimeter, L is the length, and W is the width. We are given that the width of the rectangle is 2x and the length is three times the width. So we can set up an equation that represents the given information:

P = 2L + 2W

168 = 2(3W) + 2W

168 = 8W

b) To solve for W, we can divide both sides of the equation by 8:

168/8 = W

21 = W

Therefore, the width of the rectangle is 21cm.

c) To find the length of the rectangle, we can use the expression that represents the length in terms of the width:

L = 3W

L = 3(21)

L = 63

Therefore, the length of the rectangle is 63cm.

The width and length of the rectangle are 21cm and 63cm, respectively.

we get the coordinates of Q' as (2,3) after rotation of the triangle.

What is rotation of axis?

Rotation of axes is a transformation in which the coordinate axes are rotated by a certain angle with respect to the original axes. This transformation can be used to simplify the equations of curves and to make it easier to solve problems involving them. The rotation is usually done by finding the angle of rotation, which is the angle between the original x-axis and the new x-axis. The formulae for converting coordinates from the old system to the new system can then be applied.

In the given problem, we are given that triangle PQR is located in the xy-plane with coordinates of Q being (2,-3). The task is to find the coordinates of Q' when triangle PQR is rotated 180 degrees clockwise about the origin and then reflected across the y-axis to produce triangle P'Q'R'.

To start, we apply the 180 degree clockwise rotation about the origin transformation rule to the coordinates of Q (2,-3) which gives us (-2,3).

Next, we reflect the point (-2,3) across the y-axis. Reflecting across the y-axis involves changing the sign of the x-coordinate while leaving the y-coordinate unchanged. Applying this rule,

Hence, we get the coordinates of Q' as (2,3) after rotation of the triangle.

Answer:

The approximate percentage of women with platelet counts within 3 standard deviations of the​ mean is 99.7%.

Step-by-step explanation:

We are given that the blood platelet counts of a group of women have a​ bell-shaped distribution with a mean of 247.3 and a standard deviation of 60.7.

Let X = the blood platelet counts of a group of women

The z-score probability distribution for the normal distribution is given by;

                                Z  =  \(\frac{X-\mu}{\sigma}\)  ~ N(0,1)

where, \(\mu\) = population mean = 247.3

           \(\sigma\) = standard deviation = 60.7

Now, according to the empirical rule;

Since it is stated that we have to calculate the approximate percentage of women with platelet counts within 3 standard deviations of the​ mean, or between 65.2 and 429.4, i.e;

         z-score for 65.2 =  \(\frac{X-\mu}{\sigma}\)

                                     =  \(\frac{65.2-247.3}{60.7}\)  = -3

         z-score for 429.4 =  \(\frac{X-\mu}{\sigma}\)

                                       =  \(\frac{429.4-247.3}{60.7}\)  = 3

So, it means that the approximate percentage of women with platelet counts within 3 standard deviations of the​ mean is 99.7%.

The bounds for a 95% confidence interval could be option (B) 72 and 79

We know that the 98% confidence interval has bounds of 73 and 80. This means that if we were to repeat the same experiment many times, we would expect that 98% of the time, the true population mean would fall within this range.

To find the bounds for a 95% confidence interval, we can use the fact that a higher confidence level corresponds to a wider interval, and a lower confidence level corresponds to a narrower interval.

Since we want a narrower interval for a 95% confidence level, we can expect the bounds to be closer to the sample mean. We can calculate the sample mean as the midpoint of the 98% confidence interval

(sample mean) = (lower bound + upper bound) / 2 = (73 + 80) / 2 = 76.5

Next, we can use the formula for a confidence interval:

(sample mean) ± (z-score) × (standard error)

where the z-score depends on the desired confidence level, and the standard error depends on the sample size and sample standard deviation. Since we don't have this information, we can assume that the sample size is large enough (i.e., greater than 30) for the central limit theorem to apply, and we can use the formula

standard error = (width of 98% CI) / (2 × z-score)

For a 98% confidence interval, the z-score is 2.33 (found using a standard normal distribution table or calculator). Plugging in the values, we get

standard error = (80 - 73) / (2 × 2.33) = 1.70

Now, we can use this standard error to calculate the bounds for a 95% confidence interval

(sample mean) ± (z-score) × (standard error) = 76.5 ± 1.96 × 1.70

Simplifying, we get

(lower bound) = 76.5 - 3.33 = 73.17

(upper bound) = 76.5 + 3.33 = 79.83

Therefore, the correct option is (B) 72 and 79

The equation (bd)/(b-d) = c can be used to determine how many hours a day the remaining women must work in order to produce the same number of articles each day, when some of the women have been released.

An equation is an expression used to relate two or more quantities, usually by using mathematical operators such as addition, subtraction, multiplication and division. An equation typically has an equal sign (=) as its central element, with the left and right sides of the equation representing the two sides of the equation.

The answer to this question can be determined by using the following equation: (bd)/(b-d) = c. This equation is a simple ratio that takes into account the number of hours the women work per day (b), the number of women released (d), and the number of articles produced each day (c).

For example, if a factory had 10 women working 8 hours a day and produced 100 articles each day, and 5 of those women were released, then the equation (8 x 5) / (8-5) = 100 would determine that the remaining women must work 12.5 hours per day in order to produce the same number of articles.

In conclusion, the equation (bd)/(b-d) = c can be used to determine how many hours a day the remaining women must work in order to produce the same number of articles each day, when some of the women have been released.

Answer:

Answer is B

Step-by-step explanation:

(a) The standard error of the sample mean is 3.

(b) The 95% confidence is (19.9, 30.5).

(a) The standard error of the sample mean is given by:

\(SE = s / \sqrt(n)\)

Substituting the given values, we have:

\(SE = 12 /\sqrt(16) = 3\)

Therefore, the standard error of the sample mean is 3.

(b) To find a 95% confidence interval for the population mean, we use the formula:

CI = x ± t*(SE)

where x is the sample mean, SE is the standard error of the sample mean, and t is the critical value from the t-distribution with n-1 degrees of freedom at a 95% confidence level.

Since n = 16, we have n-1 = 15 degrees of freedom. From a t-distribution table, we find that the critical value for a 95% confidence level with 15 degrees of freedom is approximately 2.131.

Substituting the given values, we have:

CI = 25.2 ± 2.131*(3) = (19.9, 30.5)

Therefore, the 95% confidence interval for the population mean is (19.9, 30.5).

What is Radical form?

When a number is written in its simplest radical form, it means that the expression has been simplified as much as possible using only radicals (square roots, cube roots, etc.) and whole numbers. The simplest radical form of a number should have no perfect square factors other than 1 under the radical.

Since overline NO is parallel to overline KL, we can use the property of similar triangles to find the length of overline NM. Triangles KLM and NMO are similar, so we can set up the following proportion:

KL / NM = LO / OM

Substituting the given values, we get:

KL / 11 = 3 / (11 - MO)

Multiplying both sides by (11 - MO), we get:

KL (11 - MO) = 3(11)

Expanding the left side, we get:

11KL - KLOM = 33

Since overline NO is parallel to overline KL, we have:

KLOM = KNO + ONM = NO + ONM = 3 + ONM

Substituting into the previous equation, we get:

11KL - 3 - ONM = 33

Simplifying, we get:

11KL - ONM = 36

We are given that NO = 3, so ON = NM - NO = 11 - 3 = 8. Therefore, ONM = 8.

Now, Substituting this into the previous equation, we get:

11KL - 8 = 36

Solving for KL, we get:

KL = (36 + 8) / 11 = 44 / 11

Therefore, the length of overline KL is 44/11, which is already in simplest radical form.
