amy & anna ate 11 and david had 1

Answer:

There were 12 donuts in the box.

Step-by-step explanation:

We are given the following information in the question:

Let x be the number of donuts in the box.

Then, according to the question

Number of donuts eaten by Amy = [tex]\frac{2x}{3}[/tex]

Number of donuts eaten by Anna = [tex]\frac{x}{4}[/tex]

Number of donuts eaten by David = 1

Total number of donuts =

Number of donuts eaten by Amy + Number of donuts eaten by Anna + Number of donuts eaten by David

[tex]\Rightarrow \frac{2x}{3} + \frac{x}{4} + 1 = x[/tex]

Solving the above equation:

[tex]11x + 12 = 12x\\x =12[/tex]

Thus, there were 12 donuts in the box.

Answer:

If "m" stands for meters, then thats not possible.

Step-by-step explanation:

if m is meters then i would say 0.075 meters i’m pretty sure

The equation y = 11x + 1 is a linear equation. All three ordered pairs, (0, 1), (1, 12), and (-1, -10), satisfy this equation.

The equation y = 11x + 1 represents a linear equation. To determine which ordered pairs satisfy this equation, we substitute the x and y values into the equation and check if the equation holds true. Let's check each option:

Based on the calculations, we can see that all three ordered pairs are valid solutions for y = 11x + 1.

Answer:

I'd say C Sets 2 and 3 contain outliers.

Step-by-step explanation:

Set 2 has an outlier of 90, while set 3 has an outlier of 40. 40 isn't as much of an outlier as 90 is, so I'm not absolutely sure. Cmakes the most sense though.

Answer: Third option.

Step-by-step explanation:

The standard deviation increases as we have more values that are far away from the mean.

For example, in data set 2, we can see that most of hour points are between 38 and 49, but we also have a point with a value of 90, so we may expect that this data set has a big standard deviation.

The data set 3 is similar, most of our points are between 24 and 31, and we have a value that is on 40, so again we have an outlier that increases the value of the standard deviation.

Noticing it we can conclude that data set 2 and data set 3 have a greater standard deviation than set 1.

The correct option is the third option.

Answer:

10/24 and 15/36, more answers possible

Step-by-step explanation:

if you multiply both the numerator and denominator by the same number, it will always be equivalent to 5/12, as you can simplify it back to that fraction.

5/12, multiply both by two, and you have 10/24

5/12, multiply both by three, and you have 15/36

10/24 and 15/36 are fractions equivalent to the given fraction.

10/24: This is equivalent to 5/12 because it can be reduced to 5/12 by dividing both the numerator and the denominator by 2.

15/36: This is another fraction equivalent to 5/12 since it can be reduced to 5/12 by dividing both the numerator and denominator by 3.

Answer:

Arranging in ascending order :  28, 46,55, 63, 73,88,

A number of terms are odd, then the median is the middle number i.e., 59.

⇒(55+63)/2=59

Answer:

the answer on e2020 is 12.

The required answer is,

f(x) + f(x) + f(x) = 3ax² + 3bx + 3c

3f(x) = 3ax² + 3bx + 3c

3f(2) = 12a  + 6b + 3c

A function is defined as a relation between a set of inputs having one output each. In simple words, a function is a relationship between inputs where each input is related to exactly one output.

Now let the function be,

f(x) = ax² + bx + c

To find,

f(x) + f(x) + f(x)

we have,

f(x) + f(x) + f(x) = (ax² + bx + c) +  (ax² + bx + c) +  (ax² + bx + c)

⇒ f(x) + f(x) + f(x) = 3(ax² + bx + c)

or, f(x) + f(x) + f(x) = 3ax² + 3bx + 3c

Similarly,

3f(x) = 3(ax² + bx + c)

or, 3f(x) = 3ax² + 3bx + 3c

now to find f(2), put x =  2 in f(x). we get,

f(2) = a2² + b2 + c

or, f(2) = 4a + 2b + c

Therefore,

3f(2) = 3(4a + 2b + c)

or, 3f(2) = 12a  + 6b + 3c

hence, the required answer is,

f(x) + f(x) + f(x) = 3ax² + 3bx + 3c

3f(x) = 3ax² + 3bx + 3c

3f(2) = 12a  + 6b + 3c

Answer:

x = (8.75 - 2 5/6) / 7.1 + (4 1/2 + 2 2/3) / 4 3/10

x = 2.5

Answer:

2  1/2

Step-by-step explanation:

Order of operations rules require that we do any work within parentheses first.  Thus, calculate (8.75 - 2  5/6); it is (5  11/12).  Next, calculate (4  1/2 + 2  2/3); it is ( 7  1/6).  So what we have now looks like:

(5  11/12) / 7.1  + (7  1/6) / (43/10)    (Note that 4  3/10 = 43/10)

Performing the two indicated divisions, we get:

5/6 + 1  2/3.

B [tex]log_{2} 42[/tex]

Step-by-step explanation:

Due to the product rule of logarithms, we can combine them as such. Then it will simplify to our answer.

[tex]log_{2} 6+log_{2} 7=log_{2} (6*7)\\\\log_{2} 42[/tex]

The single logarithm equivalent to [tex]log_2^{6} + log_2^{7}[/tex]  is [tex]log_{2} 42[/tex]. The correct answer is option B.

To express [tex]log_2^{6} + log_2^{7}[/tex] as a single logarithm, we can use the logarithmic identity log a + log b = log ab.

Applying this identity to the given expression, we get:

[tex]log_2^{6} + log_2^{7}[/tex] = [tex]log_{2} (6 * 7)[/tex]

Simplifying the expression within the logarithm, we get:

[tex]log_{2} (6 * 7)[/tex] = [tex]log_{2} 42[/tex]

Therefore, the single logarithm equivalent to [tex]log_2^{6} + log_2^{7}[/tex] is [tex]log_{2} 42[/tex]. The correct answer is option B.

Logarithms are used to simplify complex mathematical calculations involving large numbers. They allow us to break down a number into its constituent parts and perform operations on those parts more easily. In this problem, we are asked to express the sum of two logarithms as a single logarithm. To do this, we use the logarithmic identity log a + log b = log ab.

Applying this identity to the given expression, we get:

[tex]log_2^{6} + log_2^{7}[/tex] = [tex]log_{2} (6 * 7)[/tex]

We simplify the expression on the right-hand side of the equation to get:

[tex]log_{2} (6 * 7)[/tex] = [tex]log_{2} 42[/tex]

Therefore, the single logarithm equivalent to [tex]log_2^{6} + log_2^{7}[/tex] is [tex]log_{2} 42[/tex].

Answer:

4

Step-by-step explanation:

a linear function is

y = ax + b

so, for the first pair of x, y

8.5 = 2a + b

b = 8.5 - 2a

the second pair

15.25 = 5a + b

let's use the substitution information from the first pair :

15.25 = 5a + 8.5 - 2a

6.75 = 3a

a = 2.25

b = 8.5 - 2×2.25 = 8.5 - 4.5 = 4

so, we get as linear function

y = 2.25x + 4

that means the y-intercept (x = 0) is at y = 4

y = 2.25×0 + 4 = 4

The y-intercept of this function will be at (0, 4).

A linear system is one in which the parameter in the equation has a degree of one. It might have one, two, or even more variables.

In the table below, x represents miles traveled and y represents the cost to travel by train.

Miles (x)    Cost (y)

   2            8.50

   5           15.25

   8          22.00

  12          31.00

Then the linear equation will be

y - 8.50 = [(31.00 - 8.50) / (12 - 2)] (x - 2)

y - 8.50 = 2.25(x - 2)

y - 8.50 = 2.25x - 4.5

          y = 2.25 + 4

The graph of the equation is given below.

Then the y-intercept of this function will be at (0, 4).

In Geometry, a triangle is a three-sided polygon that consists of three edges and three vertices.

A triangle with sides of lengths 20, 21, and 29 is a right triangle.

Three numbers can be the sides of a triangle if the sum of two of them is greater than the third. So, since

20+21 > 29,

20+29 > 21, and

21+29 > 20

Are trivially true, they can be the sides of a triangle.

The given numbers are a Pythagorean triplet and can be the dimensions of a right triangle.

20,21 and 29 is a Pythagorean triplet, since
