Answer: a₁₄=90x-31

Step-by-step explanation:

-x-5,  6x-7,  13x-9 ...

Hence,

a₁=-x-5

a₂=6x-7

a₃=13x-9

d=a₂-a₁

d=6x-7-(-x-5)

d=6x-7+x+5

d=7x-2

aₙ=a₁+d(n-1)

a₁₄=-x-5+(7x-2)(14-1)

a₁₄=-x-5+13(7x-2)

a₁₄=-x-5+91x-26

a₁₄=90x-31

Answer:

Divide both sides by 3.

(x+2)^2=16

Square root both sides.

x+2= ± 4  (plus OR minus, can be either so we have to include both)

Minus 2 from both sides.

x=-2 ± 4

Add and minus the 4 to -2.

x = -2-4 = -6 and x=-2+4 = 2

Answer: x = -6, x = 2

Step-by-step explanation:

3(x+2)^2 = 48

(X+2)^2 = 16 —> divide both sides by 3.

(X+2) = 4 or -4 —> take square root. Remember plus or minus!

X + 2 = 4 —> make (x+2) equal to 4.

X = 2 <— solution.

X + 2 = -4 —> make (x+2) equal to -4.

X = -6 <— solution.

Answer:

the second dimension 2D

Answer:

Yes it is proportional

Step-by-step explanation:

Answer:

Yes

Step-by-step explanation:

Yes, it is proportional because x and y are going in the same direction, when y increases, x increases.

A proportional graph has x and y values that change in the same way. As long as they both increase it is proportional.

When x increases, y increases. When x decreases, y decreases.

The simplified sum of the expression ∑+1=−1 (2 − 1) is 2.

The given expression is the sum of (2 - 1) from i = -1 to n, where n = 1. Therefore, the expression can be simplified as follows:

∑+1=−1 (2 − 1) = (2 - 1) + (2 - 1) = 1 + 1 = 2

In this case, the value of n is 1, which means that the summation will only be performed for i = -1. The expression inside the summation is (2 - 1), which equals 1. Thus, the summation is equal to 1.

Adding 1 to the result of the summation gives:

∑+1=−1 (2 − 1) + 1 = 1 + 1 = 2

Therefore, the simplified sum of the expression ∑+1=−1 (2 − 1) is 2.

(a) Assuming the natural frequency follows a normal distribution, we can use a t-distribution to construct the confidence interval. The sample mean is 231.67 and the sample standard deviation is 1.55.

The sample size is n = 5, which gives us 4 degrees of freedom (n-1). The critical values for a 90% two-sided confidence interval with 4 degrees of freedom are -2.776 and 2.776 (obtained from a t-distribution table).

Using the formula for the confidence interval:

lower bound = sample mean - (t_critical * (sample standard deviation / sqrt(n))) = 231.67 - (2.776 * (1.55 / sqrt(5))) = 228.17

upper bound = sample mean + (t_critical * (sample standard deviation / sqrt(n))) = 231.67 + (2.776 * (1.55 / sqrt(5))) = 235.16

Thus, the 90% confidence interval for the mean natural frequency is [228.17, 235.16].

(b) No, the results of the calculations do not support the claim that mean natural frequency is 235 Hz. The entire confidence interval [228.17, 235.16] does not contain the value 235. Therefore, we cannot conclude that the true mean natural frequency is 235 Hz with 90% confidence.

The dependent variables in the following scenario are whether the bacon becomes moister and more flavorful and the independent variable is the cooking method.

In statistics, a dependent variable is one whose value is determined by another set of variables called independent variables. To put it simply, the dependent variable is the thing that is being tested or calculated. The dependent variable is sometimes known as the "outcome variable." In the given scenario, the chef was curious as to whether or not frying or microwaving the bacon would produce a moister and more flavorful final product. The bacon is the result of the experiment, hence it is a dependent variable.

area of brown=8

Adding all the area.

we get : x^2 + 6x +8

Using mean and outlier concepts, it is found that:

--------------------------

--------------------------

Thus, the mean is:

\(M = \frac{80 + 92 + 91 + 75 + 89 + 84 + 0 + 85}{8} = 74.5\)

Brandee's mean was of 74.5, which doesn't really represent her abilities, as in 7 of the 8 tests she got higher grades than this, but her mean is really affected by the outlier grade of 0%, for the test she missed.

--------------------------

\(M = \frac{80 + 92 + 91 + 75 + 89 + 84 + 90 + 85}{8} = 85.75\)

Brandee's new mean will be of 85.75, which increases her final grade by 11.25 points, and is a more accurate representation of her abilities, as there is not an outlier grade.

Answer: X = -10

Step-by-step explanation:

Times two to the parentheses

Minus X from both sides, left with 3X-16=-46

Add 16 to both sides 3X=-30

Divide both sides by 3

Answer X=-10

Answer:

x = -10

Steps:

2(2x - 8) = x - 46  Multiply 2 and 2x, and multiply 2 and -8

4x - 16 = x - 46  You then have this equation

-x           -x  Subtract x from both sides

Now let me stop here.  Why are we subtracting?  Because we have variables on both sides, we subtract the least number with the variable. We have 4x and we have x.  Now, x means 1x, and 1x is less than 4x. Therefore, we subtract 1x from both sides : 4x - 1x = 3x.

3x -16 = -46  Then you get this

    +16   +16  Add 16 to both sides (if it said 3x +16 = -46, then you'd subtract)

3x = -30  You now have this

3       3  You only want x, so divide 3 from both sides

x = -10  Hope this helps!

Answer: x< -30

The answer to questions are as follows- a)720 different strings that can be formed using the letters a, b, c, d, e, and f with each letter used once. b)240 different strings that can be formed using the letters a, b, c, d, e, and f with each letter used once, containing the block cd. c)120 different strings that can be formed using the letters a, b, c, d, e, and f with each letter used once, that start with the letter f.d)4 different strings that can be formed using the letters a, b, c, d, e, and f with each letter used once, that contain the blocks abc and ef.

a) To find the number of strings that can be formed using the letters a, b, c, d, e, f with each letter used formerly, we need to find the number of permutations of the letters. This can be set up using the formula for permutations of n objects taken r at a time, which is n!/( n- r)!.

In this case, we've 6 objects and we want to take all 6, so we have

6!/( 6- 6)! = 6! = 720

thus, there are 720 different strings that can be formed using the letters a, b, c, d, e, and f with each letter used formerly.

b) To find the number of strings that can be formed using the letters a, b, c, d, e, and f with each letter used formerly, that contain the block cd, we can treat the block cd as a single object and find the number of permutations of the performing 5 objects( alphabet, e, f, and the block cd). We also multiply this by the number of ways that cd can be arranged within the string( which is 2 since cd can be arranged as cd or dc).

So we have

5! * 2 = 240

thus, there are 240 different strings that can be formed using the letters a, b, c, d, e, and f with each letter used formerly, containing the block cd.

c) To find the number of strings that can be formed using the letters a, b, c, d, e, and f with each letter used formerly, that starts with the letter f, we can fix f as the first letter and also find the number of permutations of the remaining 5 objects. This can be set up using the formula for permutations of n objects taken r at a time, which is n!/( n- r)!.

In this case, we've 5 objects and we want to take all 5, so we have

5!/( 5- 5)! = 5! = 120

thus, there are 120 different strings that can be formed using the letters a, b, c, d, e, and f with each letter used formerly, that start with the letter f.

d) To find the number of strings that can be formed using the letters a, b, c, d, e, and f with each letter used formerly, that contain the blocks alphabet and ef, we can fix alphabet and ef as blocks and find the number of permutations of the remaining 2 objects( d and f). We also multiply this by the number of ways that the blocks can be arranged within the string( which is 2 since alphabet can be before ef or ef can be before the alphabet).

So we have

2 * 2! = 4

thus, there are 4 different strings that can be formed using the letters a, b, c, d, e, and f with each letter used formerly, that contain the blocks alphabet and ef.

The number of non-fiction books sold on Friday will be two-and-a-half times the number of arts and crafts books sold on Friday. Therefore, option B is the correct answer.

We can see from the table that on Thursday, 7 sports and trivia books and 19 arts and crafts books were sold, for a difference of 12.

On Thursday, 13 non-fiction books and 19 arts and crafts books were sold. If we assume that the same ratio will hold on Friday, then we can predict that the number of non-fiction books sold will be (19/2)×2.5 = 23.75, which is not a whole number.
