answer: the range is 41.

to find the range of this data set, we first need to find the minimum and maximum values - which are 59 and 100.

then we subtract the minimum from the maximum.

59 - 100 = 41.

The equation of line for the given data is y = 5x -1.

According to the given question.

We have a data of points for a equaton of line.

As we know that the standard equation of line is y = mx + b.

Where, m is the slope of line and b is the y intercept.

Since, the points which are given in the data must satisfy y = mx + b.

Therefore,

Lets take the points (1, 4) and (2, 9) and substitute it in y = mx + b to find the value of m and b.

At x = 1 and y = 4

4 = m + b ..(i)

And at x = 2 and y = 9

9 = 2m + b ..(ii)

From equation i and ii

m = 5

So, b = -5 + 4 = -1

Hence, the equation of line for the given data is y = 5x -1.

the number of pastries that she bake in the afternoon is equal to 312 pastries.

We are given that:

Saffron sells 584 pastries in the whole day and 52 pastries are left at the end of the day.

Now, we will use addition to find the total number of pastries that is being made in the day.

Total pastries = 584 + 52

Total pastries = 636

Now, she bake 324 pastries in the morning.

So, the number of pastries baked in the afternoon = 636 - 324

In afternoon = 312.

Therefore, we get that the number of pastries that she bake in the afternoon is equal to 312 pastries.

Answer:

x = 10 or x = 2

Step-by-step explanation:

Solve for x:

x^2 - 12 x + 20 = 0

Hint: | Solve the quadratic equation by completing the square.

Subtract 20 from both sides:

x^2 - 12 x = -20

Hint: | Take one half of the coefficient of x and square it, then add it to both sides.

Add 36 to both sides:

x^2 - 12 x + 36 = 16

Hint: | Factor the left hand side.

Write the left hand side as a square:

(x - 6)^2 = 16

Hint: | Eliminate the exponent on the left hand side.

Take the square root of both sides:

x - 6 = 4 or x - 6 = -4

Hint: | Look at the first equation: Solve for x.

Add 6 to both sides:

x = 10 or x - 6 = -4

Hint: | Look at the second equation: Solve for x.

Add 6 to both sides:

Answer: x = 10 or x = 2

Step-by-step explanation:

Your answer is going to be -20.

Answer:

Step-by-step explanation:

The answer is **-4**.

The number line shows that 2 is to the right of 6 on the number line. This means that 2 is greater than 6. To find the difference between 2 and 6, we can subtract 6 from 2. 2 - 6 = **-4**.

The other choices are incorrect. A is incorrect because 2 is greater than 6, so the difference between them cannot be 8. B is incorrect because 4 is the sum of 2 and 6, not the difference. C is incorrect because -3/4 is not a real number.

Rule 1: The output is the square of the input. For example, if the input is 3, then the output would be 9 (3 squared).

Rule 2: The output is 90 greater than the input. For example, if the input is 3, then the output would be 93 (3 + 90).

These are the two rules you've provided, and they describe how to calculate the output (y) based on the input (x).
Rule 1: The output is the square of the input.
In this rule, when you have an input value (let's call it x), you square it (multiply it by itself) to get the output value (y). Mathematically, this can be written as:
\(y = x^2\)
Rule 2: The output is 90 greater than the input.
In this rule, when you have an input value (x), you add 90 to it to get the output value (y).

Answer:

The sum will be close to 1/4

Step-by-step explanation:

1/8+1/6 is 7/24, and 1/4th of that is 6/24, so it is very close.

Answer: The sum will be close to 1/4

Step-by-step explanation:

You can start by making the fractions have the same denominator, (8*6) which gets you 48

You then want to use the butterfly method, so 1/8 becomes 6/48 and 1/6 becomes 8/48. You then add these up to 14/48.

12/48 is 1/4, and 14/48 is close to 12/48, thus making the answer the first option.

The coordinates of the point on the directed line segment from (-7, 9) to (3, -1) that partitions the segment into a ratio of 2 to 3 are (-3, 5).

To find the coordinates of the point that divides the directed line segment from (-7, 9) to (3, -1) into a ratio of 2 to 3, we can use the section formula.

Let's label the coordinates of the desired point as (x, y). According to the section formula, the x-coordinate of the point is given by:

x = (2 * 3 + 3 * (-7)) / (2 + 3) = (6 - 21) / 5 = -15 / 5 = -3

Similarly, the y-coordinate of the point is given by:

y = (2 * (-1) + 3 * 9) / (2 + 3) = (-2 + 27) / 5 = 25 / 5 = 5

Therefore, the coordinates of the point that divides the line segment in a ratio of 2 to 3 are (-3, 5).

To understand this conceptually, consider the line segment as a distance from the starting point (-7, 9) to the ending point (3, -1). The ratio of 2 to 3 means that the desired point is two-thirds of the way from the starting point and one-third of the way from the ending point. By calculating the x and y coordinates using the section formula, we find that the desired point is located at (-3, 5).

The average velocity for the time period beginning when t=3 and lasting for

1) 0.01 s: -9051.12 ft/sec

2) 0.005 s: -18051.06 ft/sec

3) 0.002 s: -45051.1 ft/sec

4) 0.001 s: -90051  ft/sec

Here, a ball is thrown with initial velocity of 46 ft/s.

The height of the ball in feet after t seconds is given by an equation,

 y = 21t - 12t²

Let us assume that P represents the average velocity.

The average velocity is given by formula,

P = [y(t₂) - y(t₁)]/[t₂ - t₁]

i) the average velocity for the time period beginning when t=3 and lasting  0.01 s

Here, t₂ = 3.01 s and  t₁ = 3 s

y(t₂) =  21(3.01) - 12(3.01)²

      = -45.5112

y(t₁) =  21(3) - 12(3)²

      = 45

y(t₂) - y(t₁) = -45.5112 - 45

                = -90.5112

So, P = -90.5112 / (0.01)

     P = -9051.12 ft/sec

ii) the average velocity for the time period beginning when t=3 and lasting  0.005 s

Here, t₂ = 3.005 s and  t₁ = 3 s

y(t₂) - y(t₁) = -45.5112 - 45

                = -90.2553

So, P = -90.2553 / (0.005)

     P = -18051.06 ft/sec

iii) the average velocity for the time period beginning when t=3 and lasting  0.002 s

Here, t₂ = 3.002 s and  t₁ = 3 s

y(t₂) - y(t₁) = -45.1021 - 45

                = -90.1021

So, P = -90.1021 / (0.002)

     P = -45051.1 ft/sec

iv) the average velocity for the time period beginning when t=3 and lasting  0.001 s

Here, t₂ = 3.001 s and  t₁ = 3 s

y(t₂) - y(t₁) = -45.051 - 45

                = -90.051

So, P = -90.051 / (0.001)

     P = -90051 ft/sec

Step-by-step explanation:

g(x)= ax², inc on x<0 & dec on x>0

Firstly we need to get the derivative of g(x)

g'(x)=2ax

for inc interval g'(x) should be +ve

x<0 (i.e. x= -ve), then a must be -ve

for dec interval g'(x) should be +ve

x>0 (i.e. x= +ve), then a must be -ve

so in both cases a must be a negative constant

The average number of hours that adults spend working each day is 8 hours and Ryan is correct because he got the average of 8 right.

We know that,

The sample mean is a statistic that is computed by taking the arithmetic mean of the values of a variable in a sample. If the sample is taken from probability distributions with a shared expected value, the sample mean is an estimator of that value.

The mean is gotten from the formula;

x' = ∑x/n

Number of hours of work per day are; 6, 7, 8, 9 and 10

Thus; sum up all of it

∑x = 6 + 7 + 8 + 9 + 10

∑x = 40

Mean is; x' = 40/5

x' = 8

Since Ryan concluded that the average is 8 hours,
