what is the missing value in the table below? ​

Answer:

the next number is 6

Step-by-step explanation:

i'm assuming you want to find what comes next after 25 so pretty much each number decreases by 19

The 10th term of the arithmetic sequence will be –89.

Let a₁ be the first term and d is the common difference between the terms. Then the nth term will be given as

[tex]\rm a_n = a_1 + (n - 1)d[/tex]

The sequence is given below.

82, 63, 44, 25, ......

The first term is 82 and the common difference will be

d = 63 – 82

d = –19

Then the equation will be

[tex]\rm a_n =82- (n - 1) \times 19[/tex]

Then the 10th term of the sequence will be

a₁₀ = 82 – (10 – 1) x 19

a₁₀ = 82 – 171

a₁₀ = –89

The complete question is 82 63 44 25 sequence. What is the 10 term of the sequence?

Answer:

The probability that the sample mean will be between 25.5 and 27 years is 0.1359.

Step-by-step explanation:

Let X denote of age of JSOM students.

The information provided is:

[tex]\mu=24\\\sigma=9\\n=36[/tex]

According to the Central Limit Theorem if an unknown population is selected with mean μ and standard deviation σ and appropriately huge random samples (n > 30) are selected from this population with replacement, then the distribution of the sample means will be approximately normally.  

Then, the mean of the sample means is given by,

[tex]\mu_{\bar x}=\mu\\[/tex]

And the standard deviation of the sample means is given by,

[tex]\sigma_{\bar x}=\frac{\sigma}{\sqrt{n}}[/tex]

As the sample size is large, i.e. n = 36 > 30, the sampling distribution of the average age of all the JSOM students can be approximated by the normal distribution.

Compute the probability that the sample mean will be between 25.5 and 27 years as follows:

[tex]P(25.5<\bar X<27)=P(\frac{25.5-24}{9/\sqrt{36}}<\frac{\bar X-\mu_{\bar x}}{\sigma_{\bar x}}<\frac{27-24}{9/\sqrt{36}})\\\\=P(1<Z<2)\\\\=P(Z<2)-P(Z<1)\\\\=0.97725-0.84134\\\\=0.13591\\\\\approx 0.1359[/tex]

Thus, the probability that the sample mean will be between 25.5 and 27 years is 0.1359.

Answer:

the unit rate for each pair is $1.13

Step-by-step explanation:

Okay this is how you would do this problem correctly:

we know that 4 dozen pairs of gloves cost $54.24 however we want to know what the cost is for one pair so we have to make a equation by dividing total cost by the number of glove pairs.

$54.24/4 dozen

the reason we are putting 4 dozen instead of just dividing $54.24 by 4 is because we want to know the unit price for each pair of gloves so it would actually look like this:

$54.24/4(12)

Dozen = 12

so we multiply 12 by 4 to get 48 pairs of gloves, we then divide $54.24 by 48 to find our unit rate of pricing for each pair:

$54.24/48 = 1.13

so now we place a dollar sign in front of 1.13 to get your answer:

for every pair bought it costs $1.13

So how did the Analysis A contractor get the wrong answer? well when she had bought the 4 dozen gloves she divided $54.24 by 4, which in this case would make it seem as though the gloves came in a 12 pack of gloves. However she was buying the gloves individually so she would have to multiply 4 by 12 before dividing the total number of gloves from $54.24.

Answer:

Step-by-step explanation:

The second card is influenced by the first only in that you have not replaced the first card. That makes a difference.

1/52 is the probability for the first card.

1/51 is the probability for the second card.

They are independent events. Drawing the 7 of diamonds does not make the chances of drawing the Ace of Spades other than the 7 came first and the probability of getting the Ace is slightly larger.

Step-by-step explanation:

The only way the second card is influenced by the first is if you did not swap out the first card. That alters everything.

The likelihood of getting the first card is 1/52.

The odds of getting the second card are 1/51.

They happen separately. Other than the fact that the 7 came first and the odds of receiving the Ace is a little bit higher, drawing the 7 of diamonds does not increase the chances of drawing the Ace of Spades.

Answer:

20ft²

Step-by-step explanation:

Let the length = L

Let the width = W

Perimeter of a rectangle = 2L + 2W

Translating the word problem into an algebraic equation, we have;

L = 5W .......equation 1

2L + 2W = 24 ........equation 2

To find the width

Substituting equation 1 into equation 2, we have;

2(5W) + 2W = 24

10W + 2W = 24

12W = 24

W = 24/12

Width, W = 2 ft

To find the length;

Substituting the value of "W" into equation 1, we have;

L = 5W

L = 5*2

L = 10 ft

To find the area of the rectangle;

Area = LW

Area = 10*2

Area = 20 ft²

Therefore, the deck's area is 20 feet square.

Answer:

Answer:

[tex]Length =\frac{25}{4 + \pi}[/tex] and [tex]Width = \frac{50}{4+\pi}[/tex]

Step-by-step explanation:

This question is better understood with an attachment.

See attachment for illustration.

Given

Represent Perimeter with P

[tex]P = 25ft[/tex]

Required

Determine the dimension of the rectangle that maximizes the area

First, we calculate the perimeter of the rectangular part of the window.

From the attachment, the rectangle is not closed at the top.

So, The perimeter would be the sum of the three closed sides

Where

[tex]Width = 2x[/tex]

[tex]Length = y[/tex]

So:

[tex]P_{Rectangle} = y + y + 2x[/tex]

[tex]P_{Rectangle} = 2y + 2x[/tex]

Next, we determine the circumference of the semi circle.

Circumference of a semicircle is calculated as:

[tex]C = \frac{1}{2}\pi r[/tex]

From the attachment,

[tex]Radius (r) = x[/tex]

So, we have:

[tex]C = \frac{1}{2}2\pi * x[/tex]

[tex]C = \pi x[/tex]

So, the perimeter of the window is:

[tex]P = P_{Rectangle} + C[/tex]

[tex]P =2y + 2x + \pi x[/tex]

Recall that: [tex]P = 25[/tex]

So, we have:

[tex]25 =2y + 2x +\pi x[/tex]

Make 2y the subject

[tex]2y = 25 - 2x - \pi x[/tex]

Make y the subject:

[tex]y = \frac{25}{2} - \frac{2x}{2} - \frac{\pi x}{2}[/tex]

[tex]y = \frac{25}{2} - x - \frac{\pi x}{2}[/tex]

Next, we determine the area (A) of the window

A = Area of Rectangle + Area of Semicircle

[tex]A = 2x * y + \frac{1}{2}\pi r^2[/tex]

[tex]A = 2xy + \frac{1}{2}\pi r^2[/tex]

Recall that

[tex]Radius (r) = x[/tex]

[tex]A = 2xy + \frac{1}{2}\pi x^2[/tex]

Substitute [tex]\frac{25}{2} - x - \frac{\pi x}{2}[/tex] for y in [tex]A = 2xy + \frac{1}{2}\pi x^2[/tex]

[tex]A = 2x(\frac{25}{2} - x - \frac{\pi x}{2}) + \frac{1}{2}\pi x^2[/tex]

Open Bracket

[tex]A = 2x * \frac{25}{2} - 2x * x - 2x * \frac{\pi x}{2} + \frac{1}{2}\pi x^2[/tex]

[tex]A = 25x - 2x^2 - \pi x^2 + \frac{1}{2}\pi x^2[/tex]

[tex]A = 25x - 2x^2 - \frac{1}{2}\pi x^2[/tex]

To maximize area, we have to determine differentiate both sides and set A' = 0

Differentiate

[tex]A' = 25 - 4x - \pi x[/tex]

[tex]A' = 0[/tex]

So, we have:

[tex]0 = 25 - 4x - \pi x[/tex]

Factorize:

[tex]0 = 25 -x(4 + \pi)[/tex]

[tex]-25 =-x(4 + \pi)[/tex]

Solve for x

[tex]x = \frac{-25}{-(4+\pi)}[/tex]

[tex]x = \frac{25}{4+\pi}[/tex]

Recall that

[tex]Width = 2x[/tex]

[tex]Width = 2(\frac{25}{4+\pi})[/tex]

[tex]Width = \frac{50}{4+\pi}[/tex]

Recall that:

[tex]y = \frac{25}{2} - x - \frac{\pi x}{2}[/tex]

Substitute [tex]\frac{25}{4+\pi}[/tex] for x

[tex]y = \frac{25}{2} - (\frac{25}{4+\pi}) - \frac{\pi (\frac{25}{4+\pi})}{2}[/tex]

[tex]y = \frac{25}{2} - (\frac{25}{4+\pi}) - \frac{\frac{25\pi}{4+\pi}}{2}[/tex]

[tex]y = \frac{25}{2} - (\frac{25}{4+\pi}) - \frac{25\pi}{4+\pi} * \frac{1}{2}[/tex]

[tex]y = \frac{25}{2} - \frac{25}{4+\pi} - \frac{25\pi}{2(4+\pi)}[/tex]

[tex]y = \frac{25(4+\pi) - 25 * 2 - 25\pi}{2(4 + \pi)}[/tex]

[tex]y = \frac{100+25\pi - 50 - 25\pi}{2(4 + \pi)}[/tex]

[tex]y = \frac{100- 50+25\pi - 25\pi}{2(4 + \pi)}[/tex]

[tex]y = \frac{50}{2(4 + \pi)}[/tex]

[tex]y = \frac{25}{4 + \pi}[/tex]

Recall that:

[tex]Length = y[/tex]

So:

[tex]Length =\frac{25}{4 + \pi}[/tex]

Hence, the dimension of the rectangle is:

[tex]Length =\frac{25}{4 + \pi}[/tex] and [tex]Width = \frac{50}{4+\pi}[/tex]

Answer:

$0.36

Step-by-step explanation:

Let the cost per unit of electricity  = e

Let the cost per unit of gas  = g

  a homeowner used 600 units of electricity and 100 units of gas for a total cost of 390;

   600e + 100g  = 390  ----- i

  400 units of electricity and 250 units of gas were used for a total cost of $326.

     400e + 250g  = 326 ----- ii

Now we have two equations, and we solve for g;

     600e + 100g  = 390  ----- i

     400e + 250g  = 326 ----- ii  

Multiply equation i by 4 and equation ii by 6;

    2400e + 400g  = 1560 ---- iii

    2400e + 1500g  = 1956 ---- iv

Subtract equation iii from iv;

                  1100g  = 396

                       g  = [tex]\frac{396}{1100}[/tex]   = 0.36

Cost per unit of gas $0.36
