Let the number of cookies made for other stick of butter be 'y'.

Then, number cookies for the 16  sticks of butter

3/24 = 16/ y

y = 16*24 / 3

y = 128 cookies.

Again, number cookies for the 5 sticks of butter

3/24 = 5/ y

y = 5*24 / 3

The probability that the mean systolic blood pressure of 23 women is between 119 and 122 mm Hg is 0.0579.

The Central Limit Theorem states that the distribution of the mean of a large sample (n>30) taken from a population with a finite mean and standard deviation will be approximately normal.

Since we are given that systolic blood pressures are normally distributed and we have n = 23>30, we can assume that the mean systolic blood pressure of 23 women will be approximately normally distributed with a mean of 114.8 mm Hg and a standard deviation of 13.1/[tex]\sqrt{23}[/tex] = 2.731 mm Hg.

To find the probability that the mean systolic blood pressure of 23 women is between 119 and 122 mm Hg, we can standardize the problem and use the standard normal distribution table.

We can standardize the problem by finding the number of standard deviations away from the mean of the lower and upper bounds of the range.

z_lower = (119 - 114.8) / 2.731) = 1.537

z_upper = (122 - 114.8) / 2.731) = 2.636

Now we can use the standard normal distribution table to find the probability that a standard normal variable is between z_lower and z_upper.

P(z_lower < Z < z_upper) = P(Z ≤ 2.636) - P(Z < 1.537) = 0.9958 - 0.9379 = 0.0579

Therefore, the probability that the mean systolic blood pressure of 23 women is between 119 and 122 mm Hg is 0.0579.

What is graph of the function?

The set of ordered pairs where f(x) = y is displayed as the graph of a function in mathematics. These pairs are the Cartesian coordinates of points in two-dimensional space and, in the typical case where x and f(x) are real numbers, they form a subset of this plane.

Let the graph of the function is given.

We have to find What does the graph of the function at each interval represent.

As we can see that there are three intervals of the graph are shown (1), (2), and (3).

We can see that in the first interval (1) the graph is increasing.

By means of ratio properties, the simplified form of ratio 1.5 : 20 is equivalent to ratio 3 : 40.

Ratios are relationships between two real numbers of the form a : b, the simplification of ratios can be done by using the following ratio property:

Simplification property for ratios

a : b ← (a · c) : (b · c)

Where a, b, c are real numbers.

The purpose of ratio simplification is to eliminate any decimal number in a ratio. If we know that a = 1.5, b = 20 and c = 2, then the simplified form of the ratio is:

1.5 : 20 → (1.5 · 2) : (20 · 2)

(1.5 · 2) : (20 · 2) = 3 : 40

By ratio properties, ratio 3 : 40 is the simplified form of ratio 1.5 : 20.

Answer:

y = x + 11

Step-by-step explanation:

the equation of a straight line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

calculate m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (3, 14 ) and (x₂, y₂ ) = (9, 20 )

m = [tex]\frac{20-14}{9-3}[/tex] = [tex]\frac{6}{6}[/tex] = 1 , then

y = x + c ← is the partial equation

to find c substitute either of the 2 points into the partial equation

using (3, 14 )

14 = 3 + c ⇒ c = 14 - 3 = 11

y = x + 11 ← equation of line

A line passes through points (3,14) and (9,20), linear function rule in terms of x and y for this line is y = x + 11

A linear function in slope-intercept form is y = mx + b, where m is the slope of the line and b is the y-intercept. The slope of a line passing through two points (x1, y1) and (x2, y2) can be found using the formula: m = (y2 - y1) / (x2 - x1). Plugging in the point values from the problem, we get:m = (20 - 14) / (9 - 3) = 6/6 = 1

The y-intercept  be found by plugging in any one of the point values and the slope into the equation y = mx + b and solving for b. Using the point (3,14), we get:

14 = 1*3 + b

b = 11So the linear function in terms of x and y is:

y = x + 11

A linear function is a type of mathematical function that, when graphed, defines a straight line. It is defined by the equation y = mx + b, where x and y are variables, m is the line's slope, and b is the y-intercept (the point where the line crosses the y-axis). The slope (m) of the line represents its steepness, and the y-intercept (b) represents the point at which the line intersects the y-axis.

Answer:

it would be 6 miles a day

Step-by-step explanation:

do to 41.2 miles in 1 week and a 4 mile start plus six more days it would be 6x6=36+4=40

The average speed so far is 226.4 miles per hour.

Time taken: 3 hours 49 minutes + 6 hours 27 minutes

= 10 hours 16 minutes

Total distance: 163 miles + 411 miles

= 574 miles

Average speed: 574 miles / (10 hours 16 minutes)

= 226.4 miles per hour

To calculate the average speed of the Copeland family's trip so far, we need to know the total distance they have traveled and the total time they have spent traveling. We can calculate this by adding the distance driven by Mr. Copeland (163 miles) and the distance driven by Mrs. Copeland (411 miles) to get a total distance of 574 miles. Then, we can add the time taken by Mr. Copeland (3 hours 49 minutes) and the time taken by Mrs. Copeland (6 hours 27 minutes) to get a total time of 10 hours 16 minutes. We can then divide the total distance (574 miles) by the total time (10 hours 16 minutes) to get an average speed of 226.4 miles per hour.

Yes, the equation Y = 2/3x represents a proportional relationship.

If one variable is always equal to a constant multiplied by the other variable(quantity), then we can say that those variables are in a proportional relationship.

In the direct relationship between two quantities, if one quantity increases, the other quantity also increases and vice-versa.

For example, if each square foot of carpet costs $1.50, then the cost of the carpet is proportional to the number of square feet. The direct proportion relationship is written as y ∝ x.

y = kx where k is the constant of proportionality.

The constant of proportionality is 2/3. It tells us that for every 1 unit increase in x, Y increases by 2/3 units.

The interest generated in Pauls savings account is $4.68

The amount generated in Larissa's savings account is $5015.80

Compound interest is interest that builds up over a certain length of time on both principal and interest. The principle is also used to account for the interest that has accrued on a principal over time. Furthermore, the cumulative principal value is used to calculate interest for the subsequent time period. The new way of calculating interest now utilized in all international financial and commercial operations is known as compound interest. When we look at the compound interest values that have built over various time periods, the power of compounding is clearly apparent.

The interest that is paid on both principle and interest and is compounded on a regular basis is known as compound interest. The interest is calculated for the new principal at regular intervals when the accumulated interest and the current principal are combined. The initial principal plus the interest that has already accrued make up the new principal.

The initial principal(p) of Paul is $1000

rate(r) is 5.5%

Number of days(t) = 20th March to 20th April = 31 days = 31/365 years

So the Amount generated =[tex]p * (1 + \frac{r}{365})\x^{365*t}[/tex]

⇒ A = [tex]1000* (1 + \frac{5.5}{100*365})\x^{31} = 1000*1.00468 = 1004.68[/tex]

The interest generated = 1004.68 - 1000 = $4.68

Similarly for Larissa

time = 24th Feb to 17th March = 21 days = 21/365 years

So the Amount generated =[tex]p * (1 + \frac{r}{365})\x^{365*t}[/tex]

⇒ A = [tex]5000* (1 + \frac{5.5}{100*365})\x^{21} = 5000*1.00317 = 5015.80[/tex]

To find the percent markup, we can use the following formula:

Markup = (selling price - cost price) / cost price * 100

We know that the department store buys 100 shirts at a cost of $1,200 and sells them at a selling price of $20 each.

Markup = ($20 - $12) / $12 * 100

Markup = $8 / $12 * 100

Markup = 2/3 * 100

Markup = 67%

So the percent markup is 67%.

The rate of increase of the volume of the cube is 0.8 cubic inches per second.

Let x denote the edge of the cube at any given instant.

The total surface area of the cube

= 6x^2

The given condition is: 6x^2 = 150

=> x^2 = 25

=> x = 5

Now, the rate of increase of the edge of the cube is 0.2 inches/second.

Therefore, the rate of increase of the volume of the cube = rate of increase of the edge * rate of increase of the edge * rate of increase of the edge

=> 0.2 * 0.2 * 0.2

= 0.008 inches^3/second

Since two inches are added, therefore after framing the side length becomes-

then add them up and it will give you 368.559 bacteria count. When rounded off it will be 369.

b - decrease rate

x - time in hours
