Answer:

a=11

Step-by-step explanation:

Answer:

11

Step-by-step explanation:

12a-8 = 11a +3

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

1a = 3+8

1a = 11

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

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.

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.

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.

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

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.

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.

Final answer:

The sequence shown in this question is an arithmetic sequence with a common difference of 4.

Explanation:

The sequence shown in this question is an example of an arithmetic sequence. An arithmetic sequence is a sequence in which the difference between consecutive terms is always the same. In this case, the difference between each term is 3.

To find the common difference in this sequence, we can divide any term by the previous term. For example, dividing 12 by 3 gives us a quotient of 4, which means the common difference is 4.

Therefore, the sequence is an arithmetic sequence with a common difference of 4.

Answer:

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

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.

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

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.

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.
