It's a quadratic with a positive x² coefficient, so a CUP, with a minimum

f(x) = 2x² -12 x + 13

= 2(x² - 6x) + 13

= 2(x - 3)² - 2(9) + 13

f(x) = 2(x - 3)² - 5

Since x-3 is always zero or positive the least value is

f(3) = -5

Answer: -5

The sum of nine-tenths and g is two-thirds solve for g

Answers

Answer:

- 7/30

Step-by-step explanation:

9/10 + g = 2/3

So subtract 9/10 from both sides of the equation to get g = -7/30

Thank me later :D

Final answer:

To solve for g, the sum of nine-tenths and g is two-thirds. By multiplying every term by the least common denominator and simplifying, we find that g is equal to -7/30.

Explanation:

To solve for g, we need to isolate g on one side of the equation. Given that the sum of nine-tenths and g is two-thirds, we can write it as an equation: 9/10 + g = 2/3. To eliminate the fraction, we can multiply every term by the least common denominator (LCD), which is 30. This gives us 27 + 30g = 20. Simplifying the equation gives us 30g = -7. Finally, we can solve for g by dividing both sides of the equation by 30, resulting in g = -7/30.

Subtract 7x + 4y − 2z from 4x + 2y.

Answers

Final answer:

To subtract 7x + 4y - 2z from 4x + 2y, change the signs of the second polynomial and combine like terms, yielding a result of -3x - 2y + 2z.

Explanation:

To subtract the expression 7x + 4y − 2z from 4x + 2y, we perform subtraction of polynomials by changing the sign of each term in the expression being subtracted and then combining like terms.

Change the signs of each term in the second polynomial: −(7x) − (4y) + (2z).Add this result to the first polynomial: (4x + 2y) + (− 7x − 4y + 2z).Combine like terms: (4x − 7x) + (2y − 4y) + 2z.Simplify each group of like terms: − 3x − 2y + 2z.

Therefore, the result of the subtraction is − 3x − 2y + 2z.

A recipe for 48 biscuits uses 2/2/3 cups of biscuit mix. How many biscuits are made from each cup of biscuit mix?

Answers

It would be 18 from each cup of mix

To determine how many biscuits are made from each cup of biscuit mix, divide the total number of biscuits (48) by the total cups of biscuit mix (2 and 2/3) to get 18 biscuits per cup.

The student asked how many biscuits are made from each cup of biscuit mix if a recipe for 48 biscuits uses 2 and 2/3 cups of biscuit mix. To find this out, we need to calculate the number of biscuits per cup of mix.

We start by writing the known ratios that one recipe of 12 biscuits requires 2 cups of flour, and we then scale this to 48 biscuits using unit conversions based on the ratios.

First, we calculate the number of biscuits made per one cup:

Divide the total number of biscuits by the total cups of biscuit mix used.

48 biscuits \/ (2 + 2/3) cups = 48 biscuits \/ (8/3) cups.

Multiply the number of biscuits by the reciprocal of cups:

48 biscuits * (3/8) cups = 18 biscuits per cup.

Therefore, one cup of biscuit mix yields 18 biscuits.

First we need to get the variables on one side and the constants on the other side.

So subtract 11a from both sides.

12a-11a -8 = 3

1a -8 = 3   now add 8 to each side

Jake's test scores for the first term of chemistry class were 78, 68, 73, 94, and 62. Which of the measures of central tendency would make Jake's test scores seem as high as possible? *
Mean
Median
Mode
Range

Answers

Answer:

Mean

Step-by-step explanation:

For the mean, his score is a 75 (78+68+73+94+62/5)

For the median, his score is a 73 (in order: 62 68 73 78 94, the middle number is the median)

There is no mode because there are no repeating numbers

For the range, his score is a 32. (highest - lowest: 94-62)

This should be right, hope it helps. :)

Answer:

Mean is the highest average out of all = 75

Step-by-step explanation:

The "range" of a list a numbers is just the difference between the largest and smallest values.

Ans The range = 94-62 = 32

Find the mean, median, mode, and range for the following list of values:

62, 68, 73, 78, 94

The mean is the usual average, so you add and then divide:

(62, 68, 73, 78, 94 ) ÷ 5 = 75

Ans  = mean of 75

The median is the middle value, so first I'll have to rewrite the list in numerical order:

62, 68, 73, 78, 94

Ans = median of 73  

There are five numbers in the list, so the middle one will be the 3rd number.

The mode is the number that is repeated more often than any other, so 70 if data was in 10's would be the mode.

range: 32

mean: 75

median: 73

mode: 0

An assistant is in charge of ordering lunch for the monthly office meeting. For the first month, she orders ten Falafel wraps, twenty-five Turkey BLT sandwiches, and fifteen hot Ham and Swiss paninis for a total of $361.25. The next month, she orders fifteen Falafel wraps, thirteen Turkey BLT sandwiches, and twenty-two hot Ham and Swiss paninis for a total of $342.50. For the third month, she orders eight Falafel wraps, twenty-two Turkey BLT sandwiches, and twenty hot Ham and Swiss paninis for a total of $359. How much does each sandwich cost?

Answers

The solution to the system of equations will provide the cost of each sandwich type: Falafel wrap, Turkey BLT sandwich, and hot Ham and Swiss panini.

To determine the cost of each sandwich, we can set up a system of equations based on the given information.

Let's use the variables x, y, and z to represent the cost of one Falafel wrap, one Turkey BLT sandwich, and one hot Ham and Swiss panini, respectively.

From the first month's order, we can establish the equation:

10x + 25y + 15z = 361.25.

From the second month's order, we have the equation:

15x + 13y + 22z = 342.50.

And from the third month's order, we have:

8x + 22y + 20z = 359.

By solving this system of equations, we can find the values of x, y, and z, which represent the cost of each sandwich.

The solution to the system of equations will provide the cost of each sandwich type: Falafel wrap, Turkey BLT sandwich, and hot Ham and Swiss panini.

a.9
b. 3
c. limit does not exist
d. 0

Answers

Answer:

3

Step-by-step explanation:

Evaluating the limit of the function 9n - 3n / 2n.

First we factor out n from the numerator of the function to have

F(n) = n(9-3)/2n

Cancelling the variable n at the numerator with the one at the denominator we have:

Iim f(n) = 9-3/2

Iim f(n) = 6/2

Lim f(n) = 3

This shows that the limit of the function given is 3 no matter what the variable x is tending to.

Answer: Option b) 3

Step-by-step explanation:

We want to take the limit of the equation: (9n - 3n)/2n

Let's do it:

[tex]\lim_{n \to \infty} \frac{9n - 3n}{2n} = \lim_{n \to \infty} \frac{n(9-3)}{2n} = \lim_{n \to \infty} \frac{6}{2} = 3[/tex]

Really does not matter where we are looking for the limit, because this is a constant equation, so we have that the correct option is b) 3

Angronius of Nuceria has a height of 105 inches. The mean height for all World Eaters Legion soldiers is 96.5 inches and the standard deviation of the World Eaters Legion soldiers heights is 3.6 inches.


What is the z score for Angronius's height? Round to the nearest hundredth.


Must show work to receive full credit!

What is the meaning of the Z-Score you found in Problem 1? Explain how Angronius compares to the normal World Eaters soldier.

Answers

Answer:

Z-score=2.361

Hence Angronius height about 2.3 S.D above the Eaters Legion soldiers

Step-by-step explanation:

Given:

Angronius's mean =105 inches

Eaters  Legion soldiers mean =96.5 inches.

S.D for Eaters  Legion soldiers =3.6

To Find:

What is the z score for Angronius's height

Solution:

Here z-score indicate the value of data above or below the given value hence ,it determines the given data lies how many S.D above the mean or below the mean

Z- score tell that How many S.D  your data is away from mean.

So

Z-score for Angronius =105-96.5/3.6

=8.5/3.6

=2.366

Hence it  tells that Angronius height about 2.3 S.D above the Eaters Legion soldiers

i.e 2.36*3.6= 8.5 above the Eaters Legion soldiers height

i.e 105 -96.5 =8.5

This value represents how many S.D did angronius are above the height of Eaters Legion Soldiers.

The z-score for Angronius's height is 2.36, indicating that he is significantly taller than the average World Eaters Legion soldier, standing 2.36 standard deviations above the mean height.

To calculate the z-score for Angronius's height, we use the formula: [tex]z = (X - [\mu]) / [\sigma][/tex], where X is Angronius's height, [tex][\mu][/tex] is the mean height of the World Eaters Legion soldiers, and [tex][\sigma][/tex] is the standard deviation of their heights.

Using the provided values, we have:
z = (105 - 96.5) / 3.6 = 2.36.

Therefore, the z-score for Angronius's height is 2.36 when rounded to the nearest hundredth. This means that Angronius is 2.36 standard deviations above the mean height of all World Eaters Legion soldiers. In terms of height, Angronius is significantly taller than the average World Eaters soldier.

Answers

Answer:

Answer: first one is -1 and 0

Second one is: zero falls between the values of f(x) for these inputs

Third one is: -0.9

Step-by-step explanation:

A zero can be found between the input values of -1 and 0 because zero falls between the values f(x) for these inputs.

What is Function?

A function is a relation from a set A to a set B where the elements in set A only maps to one and only one image in set B. No elements in set A has more than one image in set B.

Cubic functions are functions of the form,

f(x) = ax³ + bx² + cx + d = 0

We have input values and output values for those input values for the cubic function.

A zero of the function is the value of the input when output value equals zero.

When x = -1, f(x) = -0.5

When x = 0, f(x) = 2.5

The value of f(x) = 0 between these input values.

One zero of the function is approximately -0.9, which is more approximate.

Hence the zero of the function lies between -1 and 0.
