Step-by-step explanation:

1.  Use a calculator with distribution functions here.  We're interested in finding the area under the standard normal curve to the right of 590, given that the mean is 510 and the standard deviation is 80.  Note that 590 = 510 + 80, meaning that 590 is 1 standard deviation above the mean.

According to the Empirical Rule, 68% of data under a standard normal curve lies within 1 standard deviation of the mean.  The area from the extreme left of this curve to x = 510 is 0.500, and the additional area under the curve from 510 to 590 is 34% of the total area, or 0.340.

Thus, the desired area is 0.500 + 0.340 = 0.840.  This represents the desired probability.

2.  What percentile is a score of 750?  Find the number of standard deviations to the left of 750:

                  750 - 510

z-score = ------------------- = 24/8 = 3.00

                         80

The desired percentile is the area to the left of z = 3.00.  Using a calculator, we find this area to be 0.9987.  That 750 score is in the 99+ percentile.

Answer:

720

Step-by-step explanation:

Since we are choosing a subset of 3 people from a set of 10 people, and arranging the 3 people according to relative strength, the answer can be obtained by computing P(10,3).

 P(10,3)=10! / (10-3)!

= 10!/7!

Rewrite  10 !  as  

10 * 9  * 8  * 7 !  / 7!

Cancel the common factor of  7 !  and divide ( 10  * 9 * 8 ) by  1

10  * 9  * 8 = 720

Final answer:

To find the number of different outcomes possible when selecting and ranking three candidates out of ten, we calculate the permutations without repetition, using the formula 10! / (10 - 3)!, which yields 720 different outcomes.

Explanation:

The question asks for the number of different outcomes possible when a search committee must choose and rank three candidates out of ten for a job. This is a permutation problem because the order in which the candidates are ranked matters.

To calculate the number of different outcomes, we use the formula for permutations without repetition, which is n! / (n - r)!, where 'n' is the total number of items to choose from (in this case, the number of candidates) and 'r' is the number of items to choose and arrange (in this case, the number of candidates to be ranked). So, the number of different outcomes for selecting and ranking three candidates from ten is calculated as follows:

10! / (10 - 3)! = 10! / 7! = 10 × 9 × 8 = 720

Thus, there are 720 different outcomes possible when the search committee chooses and ranks three candidates out of ten.

Answer:

[tex] y=2.5 \sin(\pi t)[/tex]

Step-by-step explanation:

Time period $T$ is 2 sec.

$T=\frac{2\pi}{\omega}$

$\therefore 2=\frac{2\pi}{\omega}$

$\therefore \omega=\pi$

The amplitude is half the distance between highest and lowest points.

Thus, amplitude $A= 2.5$

The equation to the SHM is:

$y=A \sin (\omega t)$

Or,

$\boxed{y=2.5 \sin (\pi t)}$

The equation that models the position of the weight at time t seconds is y = 2.5 sin(πt).

A system of equations is two or more equations that can be solved to get a unique solution. the power of the equation must be in one degree.

We are given that;

Time taken to complete one cycle= 2sec

Distance from lowest to highest point= 5in

Now,

The position of the weight attached to a spring that is oscillating up and down can be modeled by a sinusoidal function of time. Specifically, the equation for the position (in inches) of the weight as a function of time (in seconds) can be written in the form:

y = A sin(ωt + φ) + k

where:

A is the amplitude of the oscillation, which is half the distance between the highest and lowest point. In this case, A = 5/2 = 2.5 in.

ω is the angular frequency of the oscillation, which is related to the period T (the time for one complete cycle) by the formula ω = 2π/T. In this case, T = 2 sec, so ω = 2π/2 = π rad/sec.

φ is the phase shift of the oscillation, which determines the starting position of the weight. Since no specific starting position is given in the problem, we can assume that the weight starts at the highest point, which corresponds to a phase shift of φ = 0.

In this case, k = (5 + (-5))/2 = 0.

Putting all of these values into the equation, we get:

y = 2.5 sin(πt + 0) + 0

Simplifying, we get the final equation for the position of the weight at time t seconds:

y = 2.5 sin(πt)

Therefore, by the equations the answer will be y = 2.5 sin(πt).

The closest answer choice is (c) -577-617, with a 30-word summary: The expression 2ū - 6v - 67, with ū = <-97, 8> and v = <77, 57>, simplifies to -723i - 393j, matching option (c).

To find 2ū - 6v in terms of unit vectors, we first need to compute 2ū and 6v, and then subtract 6v from 2ū.

Given vectors ū = <-97, 8> and v = <77, 57>, we can find 2ū and 6v as follows:

1. 2ū = 2<-97, 8> = <-194, 16>

2. 6v = 6<77, 57> = <462, 342>

Now, subtracting 6v from 2ū:

2ū - 6v = <-194, 16> - <462, 342> = <-194 - 462, 16 - 342> = <-656, -326>

Now, we need to express this result in terms of unit vectors. The unit vectors in the x and y directions are <1, 0> and <0, 1> respectively.

The final expression is then -656<1, 0> - 326<0, 1>, which simplifies to -656i - 326j, where i and j are the unit vectors in the x and y directions, respectively.

In summary, 2ū - 6v in terms of unit vectors is -656i - 326j.

Now, if we subtract 67 from each component, we get -656 - 67 in the x-direction and -326 - 67 in the y-direction:

-656 - 67 = -723

-326 - 67 = -393

So, the final result is -723i - 393j.

The closest answer choice is (c) -577-617, with a 30-word summary: The expression 2ū - 6v - 67, with ū = <-97, 8> and v = <77, 57>, simplifies to -723i - 393j, matching option (c).

2u - 6v in terms of unit vectors i and j is equal to -24i - 14j.

To find 2u - 6v in terms of unit vectors i and j using the given vectors ū = 9i + 8j and v = 7i + 5j, we perform the following calculations:

1. Multiply vector u by 2:

2u = 2(9i + 8j) = 18i + 16j

2. Multiply vector v by 6:

6v = 6(7i + 5j) = 42i + 30j

3. Subtract 6v from 2u:

2u - 6v = (18i + 16j) - (42i + 30j)

= 18i + 16j - 42i - 30j

= (18i - 42i) + (16j - 30j)

= -24i - 14j

Therefore, 2u - 6v in terms of unit vectors i and j is equal to -24i - 14j.

The probable question maybe:

Given vectors ū = 9i + 8j and v = 7i +5j. find 2u - 6v in terms of unit vectors i  and j.

Step-by-step explanation:

X score for value that is greater than 45% of the data values= 156.78.

The term "standard deviation" (or "") refers to a measurement of the data's dispersion from the mean. A low standard deviation implies that the data are grouped around the mean, whereas a large standard deviation shows that the data are more dispersed.

Given:

Mean= 140

Standard Deviation = 18

Now, using z- score

z= (x- B)/ A

So, Z score for value above 45 % of data set = 0.9987 - 0.0668=0.9319

0.9319 = ( x - 140)/ 18

x= 16.7742 + 140

x= 176. 4472

Hence, X score for value that is greater than 45% of the data values is 156.78.

Answer:

£33

Step-by-step explanation:

The share ratio is 3 :3:4

So the rational division is 3 + 3 + 4 = 10

Gordon and Malachy share is £77,

[tex] calculting \: total \: amt \: shared \\ \frac{3}{10} + \frac{4}{10} = 77 \\ \frac{3 + 4}{10} = 77 \\ \frac{7}{10} = 77 \\ total \: amt \: = \frac{77 \times 10}{7} = 110[/tex]

Carol's share =

[tex] \frac{3}{10} \times 110 = 33[/tex]

=£33

Final answer:

Gordon and Malachy's combined share corresponds to 7 parts of the ratio. One part is worth £11, and since Caroline's share is 3 parts of the ratio, she receives £33 in total.

Explanation:

The question involves dividing a sum of money according to a given ratio. Since Gordon and Malachy together receive £77, we need to first find out the ratio representing the sum of their parts and then calculate Caroline’s share.

Given the ratio of Gordon, Caroline, and Malachy’s share as 3:3:4, we can see that Gordon and Malachy’s ratio adds up to 3 + 4 = 7 parts. To find the value of one part, we divide the total amount they have (£77) by 7.

£77 divided by 7 parts equals £11 per part. Since Caroline’s share is 3 parts in the ratio, Caroline receives 3 parts times £11 per part, which equals £33. Therefore, Caroline gets £33.

The chord and the diameter are perpendicular.

Suppose that chord AB is bisected by a diameter, which interserct the chord at point C.

Now, focus on triangles OAC and OBC. They have:

So, they are congruent. In particular, this means that angles ACO and BCO are equal. Since they sum up to 180, each of them must be 90°, so the diameter is perpendicular to the chord.

In a circle, if a diameter bisects a chord (that is not a diameter), then it must also be the perpendicular bisector of that chord.

A perpendicular bisector is defined as a line that divides an angle into two equal angles. Draw the given angle first, then cut it in half, and then draw the angle's bisector.

If a diameter bisects a chord in a circle, then it must also be the perpendicular bisector of that chord. This is because the diameter is the longest possible chord in the circle, and it passes through the center of the circle, which is the point of concurrency for all the perpendicular bisectors of chords in the circle.

Therefore, it must also be the perpendicular bisector of that chord when the diameter bisects a chord.

C is seven more than four times D can be represented with this equation:

C = 4D + 7 ........eq'n [2]

We can solve by substituting [2] into [1], replacing "C".

C + D = 180

4D + 7 + D = 180
