Answer:

Jack won because he has the highest z score.

Their z scores was:

For Jack = 1.07

For Jill = 0.9

Step-by-step explanation:

Solving using z score formula

z = (x-μ)/σ, where x is the raw score, μ is the population mean, and σ is the population standard deviation.

For Jack:

Jack's mean score when playing the game is 12,400 with a standard deviation of 1500. Jack gets a score of 14,000

Jack's z score = 14000 - 12400/1500

= 1.06667

Approximately = 1.07

For Jill:

During the same period, Jill's mean score is 14,200, with a standard deviation of 2000. Jill gets a score of 16,000.

Jill's z score :

16000 - 14200/2000

= 0.9

Therefore, the person with the highest z score won and that is Jack.

Answer:

a please would be nice

Step-by-step explanation:

you really need help with that ? it is all already given in the problem description. you only need to do the 6 little calculations (anyways adding 6). what is the problem ?

a1 = 7

a2 = a1 + 6 = well ? ... ... ... 13, of course

a3 = a2 + 6 = 13 + 6 = weeeeelllll ?

a4 = a3 + 6 = 13 + 6 + 6 = weeeellll ?

a5 = a4 + 6 = 13 + 6 + 6 + 6 =

a6 = a5 + 6 = 13 + 6 + 6 + 6 + 6 =

I am really not doing your very basic and just "mechanical" work of doing simple calculations in your head or on your calculator.

I help you, when you have a problem understanding the issue, but not when you ask me to do your pure "mechanical" job that every elementary school student can do easily.

to help with the understanding, such a sequence (using this example) can then be described and every element calculated by

a(n) = a(1) + 6*(n-1)

so, for example

a20 = 7 + 6*19 = 121

so, and now that you truly understand the concept, just use your calculator (if you truly cannot do that in your head) and do your job.

Answer:

2 is the degree of the polynomial.

The height of the cone can be written as h = 3V/(π × r²).

A linear equation can be solved by equating the LHS and RHS of the equation following some basic rules such as by adding or subtracting the same numbers on both sides and similarly, doing division and multiplication with the same numbers.

The formula for the volume of cone is given as V = 1/3 × π × r² × h.

It can be written in terms of h by the method of solving a linear equation as follows,

V = 1/3 × π × r² × h

=> 3V = π × r² × h

=>  h = 3V/(π × r²)

Hence, the expression for height from the given formula can be written as h = 3V/(π × r²).

Answer:

53 meters

Step-by-step explanation:

The angle between a viewer's horizontal line of sight and the line of sight down towards a particle is called the angle of depression. For example if a viewer is sitting at the top of a tower and looking down on a car, the angle between the viewer's horizontal line of sight and the line of sight to which he looks at the car is the angle of depression.

A sketch of the positions of the boats and the tower has been attached to this response.

As shown,

the distance between the two boats A and B is marked x meters.

the horizontal distance between boat A and the foot of the tower is y meters.

the horizontal distance between boat A and the foot of the tower is  x + y meters.

the height of the tower is 60 meters.

the angle of depression of boat A is 28°

the angle of depression of boat B is 45°

To find the value of y, from triangle DBC we use the trigonometric ratio for tangent. i.e

tan 45° = [tex]\frac{60}{y}[/tex]

1 = [tex]\frac{60}{y}[/tex]

y = 60 meters

To find the value of x, from triangle ABC we use the trigonometric ratio for tangent. i.e

tan 28° = [tex]\frac{60}{x+y}[/tex]

Where y = 60 meters

tan 28° = [tex]\frac{60}{x+60}[/tex]

0.5317 = [tex]\frac{60}{x+60}[/tex]

x + 60 = [tex]\frac{60}{0.5317}[/tex]

x + 60 = 112.85

x = 112.85 - 60

x = 52.85 meters

Therefore, boat A is about 53 meters from boat B
