Answer:

S₁₆ = 488

Step-by-step explanation:

the sum to n terms of an arithmetic sequence is

[tex]S_{n}[/tex] = [tex]\frac{n}{2}[/tex] [ 2a₁ + (n - 1)d ]

where a₁ is the first term and d the common difference

here a₁ = 8 and d = a₂ - a₁ = 11 - 8 = 3 , then

S₁₆ = [tex]\frac{16}{2}[/tex] [ (2 × 8) + (15 × 3) ]

     = 8(16 + 45)

     = 8 × 61

     = 488

The mass (in grams of each muffin out of the 100 muffins is 5802 g

given data

number of identical muffins = 100

Total mass of muffins = 5802 g

Deductions from the question

let each muffin have a mass of x such that

100 * x = 5820

100x = 5802

x = 5802 / 100

x = 58.02

Therefore the mass of each muffin is 58.02 g. and this results to mass of 100 muffins being 5802 g

Step-by-step explanation:

12/x = x/16

x^2 = 192

x = ± √192 = ± 8√3

The mean is 2 Pounds and the standard deviation is 0.3340 for the population of products produced with this process

Sampling distributions are sets of data that can depict probability for all feasible samples taken from a population. Every one of these distributions is measured for a specific measure. The sampling distribution of means, for instance, calculates the average value for all feasible samples of a certain size.

Given that:

30 samples are used (n).

X stands for the sample mean weights.

Over 2.1 pounds make up 5% of the x values, while under 1.9 pounds makeup 5%.

Let the mean and standard deviation of the goods produced by this process be the population measurements.

According to the central limit theorem, if the sample size is greater than 30, any population distribution would result in a normal sampling distribution of means.

Let x represent the weights' sample mean.

x ∼ N(μX, σX2)

∼ N(μ, σ / √n)

∼N(μ, σ / √30)

5% of the x values are over 2.1 pounds and 5% are under 1.9 pounds, according to the statistics provided.

Therefore, P(x > 2.1) = 0.05

P [x − μ / (σ / √30) > 2.1 − μ / (σ / √30)] = 0.05

P [Z > 2.1 − μ / (σ / √30) = 0.05     --- (1)

P(x < 1.9) = 0.05

P [x − μ / (σ / √30) > 1.9 − μ / (σ / √30)] = 0.05

P [Z < 1.9 − μ / (σ / √30) = 0.05     --- (2)

The Z-scores that fulfill equations (1) and (2) using the common normal table are:

P(Z < −1.64) = 0.05

P(Z > 1.64) = 0.05     (An assortment of standard normative services)

Equations (1) and (2) are used to compare the values:

2.1 − μ / (σ / √30) = 1.64 ⇒ μ = 2.1 − 0.2994σ     -- (3)

1.9 − μ / (σ / √30) = -1.64 ⇒ μ = 1.9 + 0.2994σ     -- (4)

Adding the equations (3) and (4) :

σ = 2 − 1.9 / (0.2994) = 0.3340

In light of this, the population's mean weight is 2 pounds, and its standard deviation is 0.3340 pounds.

In mathematics, an algebraic expression is one that was created using integer constants, variables, and algebraic operations

The amount spent on a new house exists $ 810,000.

Using letters or alphabets to represent numbers without giving their exact quantities is the idea behind algebraic expressions. In mathematics, an algebraic expression is one that was created using integer constants, variables, and algebraic operations (addition, subtraction, multiplication, division, and exponentiation by an exponent that is a rational number).

If n 5, the roots of a degree n polynomial expression, or the solutions of a degree n polynomial equation, may always be expressed as algebraic expressions.

An algebraic solution is what we refer to as a solution to an equation. But if n is greater than five, the Abel-Ruffini theorem asserts that only certain of these equations have algebraic solutions.

Abby spent 1/6 of the lottery on a new car

and 3/4 of the lottery on a new house

Total expenditure = $990,000

a. Let w be the lottery winnings,

then, 1/6 x w + 3/4 x w = $990,000

b. ⇒ w/6 + 3w/4 = $990,000

simplifying the above equation, we get

⇒ (2w + 9w)/12 = $990,000

⇒ 11w = 12 x $990,000

⇒ w = 12 x $990,000/11

⇒ w = 12 x 90,000

⇒ w = $1,080,000

Therefore, the lottery winnings = $1,080,000

Amount spent on a new car = 1/6 x $1,080,000 = $ 180,000

The warranty period should be 26 months so that the manufacturer will not have more than 8% of the food returned.

In a set with mean μ and standard deviation σ, the z-score of a measure X is given as:

Z = ( X - μ ) / σ

The Z-score calculates the deviation of the measure from the mean in standard deviations. We glance at the z-score table after determining the Z-score to determine the p-value connected to it. The likelihood that the measure's value is less than X, or the percentile of X, is represented by this p-value. The likelihood that the value of the measure is greater than X is obtained by deducting 1 from the p-value.

Cook-Easy blender has a mean time before failure of 32 months with a standard deviation of 4 months

Therefore,

σ = 4 and μ = 32

The warranty period should be in the 8th percentile.

Therefore, the value of X when Z has a p-value of 0.08, so X when Z = - 1.405.

So,

- 1.405 = ( X - 32 ) / 4

- 1.405 × 4 = X - 32

- 5.62 = X - 32

X = 26.38

How do you find the mean?

1. Add all values in your data

2. Divide the sum by how many numbers there are.

Using the midpoint formula, the coordinates of L is determined as: (-10, 10).

To find the coordinates of the midpoint of a segment, we have to apply the midpoint formula, which is: (x, y) = [(x2 + x1)/2, (y2 + y1)/2].

Given the following:

Substitute the given values into the midpoint formula:

(-4, 2) = [(x2 + 2)/2, (y2 + (-6))/2]

(-4, 2) = [(x2 + 2)/2, (y2 - 6)/2]

Solve for x2:

-4 = (x2 + 2)/2

2(-4) = x2 + 2

-8 = x2 + 2

-8 - 2 = x2

x2 = -10

Solve for y2:

2 = (y2 - 6)/2

2(2) = y2 - 6

4 = y2 - 6

4 + 6 = y2

10 = y2

y2 = 10

Step-by-step explanation:

Given:  -9 −︱9 + (-3) + (-5)︱ ;

We are to simplify this expression by using the 'order of operations'—as follows:
__________________
BE  MD AS   ;  or:  PE  MD AS
       ⇒   ⇒                      ⇒    ⇒
__________________
  which is a mnemonic device to remember the "order of operations":
       Be Excused, My Dear Aunt Sally (Susan).

or:  Please Excuse My Dear Aunt Sally (Susan).

Note:  the "B" stands for "Brackets" ,
and the  "P" stands for "Parentheses."

Note that "parentheses" can function as "brackets."
The "E" stands for "Exponents".
 → The "Brackets/Parentheses" —if they occur; take priority.

Then:  MD for "Multiplication and Division" are the next priority;
            ⇒
________
 →  and that neither takes priority over the other. Take note of the " ⇒ " symbol" below the "MD".  This means that we perform "multiplication and division"—as they occur, from the far left of ["beginning of"] the expression to the end of the expression.
 Then:  We do the same with "Addition and Subtraction"—from the beginning to the end of the expression, in that order [that is, from "left to right"—as/if they occur]—hence the "⇒" notation.
_____________________
So again, our given expression is:
 " -9 −︱9 + (-3) + (-5)︱ " ;

So; we have an "absolute value" (the positive integer of what is enclosed within the "vertical lines" that indicate "absolute value"—or, if the value of what is enclosed within the "vertical lines" is "0" [zero], then the absolute value would be "0" [zero]; since the absolute value of 0 is 0.
____________
So, let's start simplifying by using the 'order of operations.'
  Do we have brackets or parentheses?  No; except for the absolute value lines — which do take priority. The parentheses within those lines do not count for our purposes—but if they did, then we would use the order of operations within the "absolute value" bars!
       So as a matter of 'semantics', we could say: 'Yes"; that the absolute value bars function as "brackets."

 Do we have any "exponent(s)"?  No.
 Is there any multiplication/division? No.
 Do we have any addition or subtraction?  Yes; only one:
              →   " - 9 −︱9 + (-3) + (-5)︱.
             →   {not including the addition and subtraction within the absolute value bars.}.
____________
Let's start by simplifying the expression within the absolute value bars:
  ︱9 + (-3) + (-5)︱;

Note: The only operations are additional and subtraction; so we just calculate from left to right; as these operations  occur:
 " 9 + (-3) " = 9 − 3 " ;  Note:  Adding a "negative value" is the same as subtracting a "possible value" ;
 to get:  " 6 " ;  
 Then:  the next step is:
     " 6 + (-5) " = 6 − 5 " ;  Note:
Adding a "negative value" is the same as subtracting a "positive value" ;
      to get:  " 1 ".
Now, the absolute of  " 1" is " 1".

 → or; write as: ︱1︱= 1 .  

Now, we can rewrite the entire expression:

 " - 9 − 1 " ;  to calculate and simplify:  
   to get:  " - 10 " .

The line that passes through the point (-2,-1) and has a slope of 5. The equation of the line is y + 1 = 5(x + 2).

A line's slope in mathematics is defined as the ratio of the change in the y coordinate to the change in the x coordinate. Both the net change in the y-coordinate and the net change in the x-coordinate are denoted by y and x, respectively. The ratio of the increase in elevation between two points to the run in elevation between those same two points is referred to as the slope.

Using the slope and 1 point format:   (y- y₁) = m(x - x₁)  

where m = slope = 5, and point is (x₁, y₁). In this case point (x₁, y₁) = (-2, -1)

x₁ = -2,  y₁ = -1

Using: (y- y₁) = m(x - x₁)

y - -1 = 5(x - -2)
