The average high temperature in degrees for a city are listed 58,61,71,77,91,100,105,102,95,82,66,57 if a value of 48 is added to the data how does the median change

Answers

If a value of 48 was added, the median of the data-set would remain decay from 79.5 to 77.

How to obtain the median of a data-set?

The median of a data-set is the middle value of a data-set, the value of which 50% of the measures are less than and 50% of the measures are greater than.

The ordered data-set for this problem is given as follows:

57, 58, 61, 66, 71, 77, 82, 91, 95, 100, 102, 105.

The data-set has an even cardinality of 12, hence the median is the mean of the 6th and the 7th elements, as follows:

(77 + 82)/2 = 79.5.

A value of 48 would be lowest value of the data-set, the cardinality would be odd, and thus the middle value would be of 77.

How many integers greater than 5400 have both of the following properties :
a) the digits are distinct.
b) the digits 2 and 7 do not occur,

Answers

There are 94830 integers greater than 5400

At first, go it looks .like an infinite number but As digits are distinct

so a maximum 10 digits number is possible

but 2 & 7 can not be used so the maximum 8-digit number can be there

Total number = 4 digits numbers, 5 Digits numbers, 6 digits number, 7 digits numbers, 8 digits numbers

All the 5 - 8 digit numbers would  be > 5400

Available number of Digits = 8  ( 0, 1, 3, 4, 5, 6, 8, 9)

for numbers greater than 4 digits (5 - 8 Digits),  1st  digit can be  1, 3, 4, 5, 6, 8, 9 then from the 2nd digit onward 0 can also be a digit but the already used digit can not be used. and further one digit (already used) will keep reducing

5  Digits numbers = 7 * 7 * 6  * 5 * 4  = 5880

6 Digit Numbers =  7 * 7 * 6  * 5 * 4 *3 =  17640

7  Digits numbers = 7 * 7 * 6  * 5 * 4*2  = 35280

8 Digit Numbers =  7 * 7 * 6  * 5 * 4 *3*2*1 =  35280

Now in 4-digit numbers

Number starting with 6, 8, 9   > 5400   & number starting with 5

Number starting with 6 , 8 , 9 = 3 * 7 * 6 * 5 = 630

Number starting with 5, the second digit must be 4, 6, 8, 9

Number starting with 5 = 1 * 4* 6 * 5 = 120

Total integers greater than 5400

=5880 + 17640 + 35280 + 35280 + 630 + 120

(A) tan^−1(2)
(B) tan^−1(√2)
(C) tan^−1(1/2)
(D) 2tan^−1(1/2)

Answers

The angle θ of thread deflection in the extreme position is given by tan^−1(2).

The angle of thread deflection in the extreme position can be calculated by using the equation of motion of a simple pendulum.

The equation of motion for a simple pendulum is given by m g L sinθ = m a. Here, m is the mass of the ball, g is the gravitational acceleration, L is the length of the thread and θ is the angle of the thread.

From the given condition, the acceleration of the ball in the extreme and lowest positions are equal. This implies that the acceleration of the ball in the extreme position is equal to the acceleration due to gravity.

Therefore, the equation of motion reduces to g L sinθ = g. Solving for θ, we get sinθ = 1, which implies that θ = tan^−1(2).

Therefore, the angle θ of thread deflection in the extreme position is given by tan^−1(2).

Find the equation of the line containing the point

Answers

Answer:

y = -5x + 7

Step-by-step explanation:

Parallel lines on a graph have the same slopes/gradients.

m1=m2

First you want to rewrite the equation of the graph given. So put the 5x to the other side and you will have:

y = -5x -2

This means that the equation that we need must have the gradient -5 (bc it is m in y=mx+c)

The equation will be y = -5x + c

However we must still find c aka the y intercept.

Sub the point we are given (1,2) into the equation

We will have:

2 = -5(1) + c

2 = -5 + c

7 = c

Now that we know c, we know what the equation of the line is. Just sub it in (without 1 and 2)

y = -5x + 7

Answers

The series discount of 20/10/10 means that there are three discounts given in sequence. The first discount is 20%, the second is 10%, and the third is 10%.

What does math's % mean?

In essence, percentages are fractions with a 100 as the denominator. We place the percent symbol (%) next to the number to indicate that the number is a percentage. For instance, you would have received a 75% grade if you answered 75 out of 100 questions correctly on a test (75/100).

Let's call the original price x.

x - (20/100x) = 0.8x

then

0.8x - (10/1000.8x) = 0.72x

and finally

0.72x - (10/100*0.72x) = 0.648x

So, the net cost of $453.60 is equal to 0.648x.

We can find the original price by dividing the net cost by 0.648:

x = $453.60 / 0.648 = $700

bridge is a card game in which the deck of 52 cards is randomly and equally divided among the 4 players. so each player gets 13 cards.

Answers

The formula for calculating the number of cards each player receives in Bridge is N/4, where N = number of cards in the deck.

For a standard deck of 52 cards, each player would receive 52/4 = 13 cards. This can be further simplified to 13.33, however, since cards cannot be divided, the result is rounded down to 13 cards. Therefore, each player in a Bridge game with a standard deck of 52 cards will receive 13 cards.

The total number of cards in the deck is 52, so each player will get 13 cards. This can be expressed mathematically using the formula P = 52/4, where P is the number of cards per player. Therefore, P = 13. We can also use the formula to calculate the number of players if we know the total number of cards. For example, if we have 156 cards, the number of players can be calculated using the formula P = 156/4, which gives us P = 39. Therefore, there will be 39 players in the game.

given the system of linear equations, written in column form as follows which of the following is the corresponding row form of this system?

Answers

The row form of the system is 5x = 2 and y – y = 0.

Column form:

3x + y = 5

2x – y = –3

Row form:

3x + 2x = 5 – 3

y – y = 0

The row form of this system is 3x + 2x = 5 – 3 and y – y = 0. To convert from column form to row form, the first step is to eliminate the y terms in the equations. To do this, we need to add the two equations together. This gives us:

3x + y = 5

2x – y = –3

3x + 2x = 5 + (–3)

y – y = 0

5x = 2

y – y = 0

Finally, we can solve for x and y.

5x = 2  ⇒  x = 2/5

y – y = 0  ⇒  y = 0

Therefore, the row form of the system is 5x = 2 and y – y = 0.

find values of a, b, and c (if possible) such that the system of linear equations has a unique solution, no solution, and infinitely many solutions. (if not possible, enter impossible.) x y

Answers

The solution of the system of linear equations has infinitely many solutions.

Linear equation is defined as an algebraic equation of the form y=mx + b. involving only a constant and a first-order term, where m is the slope and b is the y-intercept.

Here we have given that the following linear equations are given then are listed as follows:

x + y = 4

y + z = 4

x + z = 4

ax + by + cz = 0

Here we have know that the  sub-system consisting of 3 first equations has a unique solution x = y = z = 2.

While we add the fourth equation, then it becomes look like as follows:

=> 2a + 2b + 2c = 0

When we simplify this one then we get,

=> a + b + c = 0.

Which means that if  a + b + c = 0,   then the system of 4 equations has a unique solution otherwise it is IMPOSSIBLE to this system to have infinitely many solutions.
