Probability that the sample mean rent is less than $2,918.03 is 0.050154

We are given that the Real Estate Group NY reports that the mean monthly rent for a one-bedroom apartment without a doorman in Manhattan is $2886. Assume the standard deviation is $586.

Also, a real estate firm samples 94 apartments.

Let X  = sample mean rent

The sample mean's z-score probability distribution is provided by;

              Z =  X-u/σ/[tex]\sqrt{n}[/tex] ~ N(0,1)

where,  u= population mean monthly rent = $2,886

             σ = standard deviation = $586

             n = sample of apartments = 94

Now, the probability that the sample mean rent is less than $2,918.03 is given by = P( < $2,918.03)

P( < $2,918.03) = P(Z < 0.52)= 0.050154

The above probability is calculated using z table by looking at value of x = 0.52 in the z table which have an area of 0.050154

Therefore, probability that the sample mean rent is less than  $2,918.03is 0.050154

The distance around the triangle is equivalent to 13x/12.

A triangle is a polygon with three edges and three vertices. The sum of all the angles of a triangle is 180 degrees. Mathematically -

∠x + ∠y + ∠z = 180°

The sum of two sides of a triangle is greater then the third side. Mathematically -

a + b > c

There are different types of triangles such as -

equilateral triangle , scalene triangle , isosceles triangle etc.

Given are the sides of triangle as x/2, x/3, x/4

The distance around the triangle is equivalent to perimeter of triangle. We can write perimeter as -

P = x/2 + x/3 + x/4

P = (6x + 4x + 3x)/12

P = 13x/12

Therefore, the distance around the triangle is equivalent to 13x/12.

The difference in solving equations with cubes and squares is of one additional step of reducing the cubic equation to a quadratic equation. In this way, a quadratic equation (variable raised to power 2) is separated from the given cubic equation.

For example, x3+3x2+x1+3=0 can be reduced to (x+3) and (x2+1), where the later one is a quadratic equation. This step is never part of a squared equation’s solution.

The similarity is from here onwards. Quadratic equations are solved similarly in both cases. Although there are multiple possibilities for roots differing from each other in nature. But once a quadratic equation is developed, the solution from there onwards is mostly generic.

Step-by-step explanation:

First, add up the total and find a number divisible for your total which is 105. The next step will be to divide by a number that can go into it easily, like 3 for example. then you would get 35. Since we want the most groups try a number *2 of 3 and that will be 6. After you divide you'll get 17.5 . and since there isn't .5 of a person you go to the lowest number ( not rounding ) and that'll be 17 since 105 divide another multiple of 3 would get you 11.66 repeated.

The product of prime factors of 900 in index form is [tex]2^{2} *3^{2} *5^{2}[/tex] and the ascending order of prime factors is 2, 3 and 5.

According to the question,

We have the following number:

The effect of eliminating the lowest value, 0, from the data set have on the mean and median of the data set is;

The mean of a given data is the sum of all observations divided by the number of observations

The median of a given set of data refers to the middlemost observation, obtained after arranging the data in ascending or descending order.

Given data:

0, 40, 60, 70, 75, 80, 85, 95, 95, 100

a) Mean without '0' = (40+ 60+ 70+ 75+ 80+ 85+ 95+ 95+ 100) / 9

= 700/9

= 77.777

Median without '0' = 40, 60, 70, 75, 80, 85, 95, 95, 100

= 80

Mean with ' 0' = 0+ 40+ 60+ 70+ 75+ 80+ 85+ 95+ 95+ 100 / 10 = 70

Median with '0' = 0, 40, 60, 70, 75, 80, 85, 95, 95, 100

= (75 + 80) / 2

= 77.5

So therefore,

Difference in mean = Median without '0' - Mean with ' 0'

= 77.77 - 70

= 7.7

Difference in median = Median without '0' - Median with '0'

= 80 - 77.5

= 2.5

1. The maximum and the minimum number of guests that Trevor and Michael should host at the banquet are 18 and 14, respectively.

2. The minimum number of tables that Trevor and Michael will need for the banquet is 2.

We can employ the mathematical operations of addition, multiplication, division, and subtraction to determine the numbers.

Since the budget is limited to $450 or less, we can compute the maximum and the minimum number of guests for the event, using division operation.

Total budget for the banquet = $400 ± $50

Cost per guest = $25

Maximum number of guests to expect = 18 ($450/$25)

Minimum number of guests to expect = 14 ($350/$25)

The number of guests a table can accommodate = 7

The minimum number of tables to use for the banquet = 2 (14/7)

The maximum number of tables to use = 3 (18/7)

Thus, using division operation, Trevor and Michael should expect to host between 14 and 18 guests at the banquet.

Answer:

x = 3.5 hours

y = 1.5 hours

Step-by-step explanation:

There are two unknowns, x and y, both in umits of hours.  We need at least two equations before we start trying to solve this with substitution.  Looking at the information, this should be possible.

First, we know that Speed x Time = Distance.  

The distance covered by the cyclyst would be the sum of (12km/h)*x and (16km/h)*y, where x is the time, in hours, for the slower speed and y for the faster.  Together, the student travels 66 km.

The total distance of 66 km would be comprised of the two distances 12x and 16y:

 12x + 16y = 66 km  

For the second equation, we know that the total time is 5 hours.  That would be the sum of x and y:

 x + y = 5 hours

We now have 2 equations, so we stand a good chance of finding the answer.  Pick one of the equations and isolate one of the variables to one side.  Let's choose x + y = 5 hours, since that is easy to rearrange:

     x = 5-y

Now take the first equation and substitute the definition of x from above (5-y):

12x + 16y = 66

12(5-y) + 16y = 66

60-12y + 16y = 66

4y = 66-60

4y = 6

y = (6/4) or 1.5 h

The time spent at 16 km/h was 1.5 hours.

Use this value of y in either equation to find x.  Let's use x+y=5, since that will be easier:

x+y = 5 for y = 1.5

x+1.5 = 5

x = 3.5h

The time spent at 12 km/h was 3.5 hours

The old monthly payment was =  10.67 x 70 = 746.9

The new monthly payment is = 11.72 x 70 = 820.4

The percent increase in his monthly payment is =9.8406%

Given,

Sandra Williams bought a home with a 11.5% adjustable rate mortgage for 20 years. He paid $10.67 monthly per thousand on his original loan

According to the question:

So, per thousand value of $70,000 is 70000/1000 =70

Now, the old monthly payment was =  10.67 x 70 = 746.9

He decides to renew and will now pay $11.10 monthly per thousand on his loan.

So, the new monthly payment is = 11.72 x 70 = 820.4

The percent increase in his monthly payment is= 11.72 /10.67 - 1 x 100

9.8406 % and to nearest tenth it is 9.8406%

Hence,  the old monthly payment was =  10.67 x 70 = 746.9

Answer: 25

Step-by-step explanation:

Using the relationship of permutation and combination, we can say that the relation [tex]${ }^n p_r=(n-\Gamma+1)^n p_{r-1}$[/tex] holds true.

What is Permutation?

The process of placing all the components of a set into a certain sequence or order is known as permutation in mathematics. In other terms, the process of permuting is the reordering of the components of a set if the set is already ordered. Nearly all areas of mathematics include permutations in some form or another. They frequently appear when various orderings on certain finite sets are taken into account.

What is Combination?

Contrary to permutations, the order of selection is irrelevant when choosing elements from a collection using the combination method. The number of combinations may be counted in simpler situations. The combination is the taking together of n items, k at a time, without repetition. The words k-selection or k-combination with repetition are frequently used to describe combinations when repetition is permitted.

In the given question:

To proof:

[tex]${ }^n p_r=(n-\Gamma+1)^n p_{r-1}$[/tex].

Let's Proof the relation:

Using the basic relation of permutation and combination, we have;
