The number of days in June is 30

The number of days in July = 31

The number of days in August = 31

The maturity date for a loan taken out on June 6 for 73 days is August 28.

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

The date on which the loan was taken = June 6.

The number of days for the loan to mature = 73 days.

Now,

The number of days in June is 30

The number of days in July = 31

The number of days in August = 31

Now,

There are (30 - 6) = 24 days remaining in the month of June.

So,

24 + 31(July) = 45 days.

Now,

73 - 45 = 28 days need to be taken from August.

So,

45(July) + 28(August) = 73 days.

This means,

The maturity date is August 28.

Answer: To answer this question, we need to perform a hypothesis test. The null hypothesis is that the standard deviation of the process is 2 mg or less, and the alternative hypothesis is that the standard deviation of the process is over 2 mg.

To test this hypothesis, we need to calculate the test statistic, which is the z-score. The z-score tells us how many standard deviations a given data point is from the mean. In this case, the z-score is calculated by subtracting the mean of the sample from the hypothesized mean of the population, and dividing that difference by the standard deviation of the sample:

z = (20.2 - 20) / 2.4 = 0.1

Since the z-score is positive, we know that the mean of the sample is greater than the hypothesized mean of the population. However, we need to compare this z-score to the critical value to determine whether it is statistically significant.

The critical value is the z-score that marks the cutoff between the region of acceptance and the region of rejection of the null hypothesis. For a 1% level of significance, the critical value is the z-score that marks the 99th percentile of the normal distribution. Since the normal distribution is symmetrical, this means that the critical value is 2.58 standard deviations from the mean.

Since the z-score we calculated is less than the critical value, we cannot reject the null hypothesis. This means that we cannot assert that the standard deviation of the process is over 2 mg at a 1% level of significance.

Modified Euler's method is a numerical method used to solve ordinary differential equations (ODEs). It is a variation of Euler's method that is more accurate than the original, but still relatively simple to implement. It works by taking a single iteration of the Euler method, then using the midpoint between the current and previous points to calculate the next point in the sequence. This is done in order to reduce the error.

Solution

We have, y(0) = 0

dy/dt = 1 – y

h = 0.1

Using modified Euler's method,

y(0.1) = y(0) + (1/2) h (f(t0, y0) + f(t0 + h, y0 + hf(t0, y0)))

= 0 + (1/2) (0.1) [(1 - 0) + (1 - 0 + 0.1)]

= 0.05

Similarly,

y(0.2) = 0.1 + (1/2) (0.1) [(1 - 0.05) + (1 - 0.1 + 0.1)]

= 0.0975

Answer: 110

Step-by-step explanation: If the drama class sold 20 more adult tickets than student tickets to the fall play, and adult tickets cost $8, then the number of adult tickets sold can be calculated by adding 20 to the number of student tickets sold and multiplying by $8. We can set up an equation to represent this relationship, where A represents the number of adult tickets sold and S represents the number of student tickets sold:

A = S + 20

A * 8 = $880

We know that the total amount collected from ticket sales was $880, and we know that adult tickets cost $8, so we can divide $880 by $8 to find the number of adult tickets sold:

A = $880 / $8

A = 110

Therefore, the drama class sold 110 adult tickets to the fall play.

Answer:

q = [tex]\frac{1}{2}[/tex]

Step-by-step explanation:

given a quadratic equation in standard form

ax² + bx + c = 0 ( a ≠ 0 )

then the nature of the roots can be found using the discriminant

Δ = b² - 4ac

• if b² - 4ac > 0 then roots are real and irrational

• if b² - 4ac = 0 then the roots are real and equal

• if b² - 4ac < 0 then the roots are not real

qx² - 6x + 18 = 0 ← is in standard form

with a = q , b = - 5 , c = 18

for one repeated (equal) real root , then

b² - 4ac = 0 ( substitute values )

(- 6)² - (4 × q × 18) = 0

36 - 72q = 0 ( subtract 36 from both sides )

- 72q = - 36 ( divide both sides by - 72 )

q = [tex]\frac{-36}{-72}[/tex] = [tex]\frac{1}{2}[/tex]

The constant of proportionality of the given linear graph is; 3/5

The constant of proportionality is defined as the ratio of two proportional values that is said to be in a constant value.

Now, in this case where we have a graph, the constant of proportionality is equivalent to the slope of the graph.

The slope will be gotten using two coordinates (x₁, y₁) and (x₂, y₂) with the formula;

m = (y₂ - y₁)/(x₂ - x₁)

Let us use two coordinates on the graph (0.5, 0.3) and (1, 0.6)

m = (0.6 - 0.3)/(1 - 0.5)

m = 0.3/0.5

m = 3/5

The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.

The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.

The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is

m=y₂-y₁/x₂-x₁

From the given graph let us take two points (0, 5) and (1,2).

m=2-5/1=-3.

Now let us find the y intercept.

Here we have

Distance    6 feet   -     -

Time          15 sec   -    21 sec  

As we know,  

Distance will be directly proportional to Time

=> Distance ∝ Time

=> Distance = K (Time)  

=> Distance/Time = k  

Where  k is the proportionality constant

By the above calculations

If Distance and Time are directly proportional then Distance/Time must be a constant

Now use the above condition to get the missing value

At a distance of 6 feet and a time of 15 sec

=> Distance/Time = 6/15

Let the missing value is x, and the time is 21 sec

=>  Distance/Time = x/21  

As we Distance/time will be constant

=>  6/15 = x/21

=>  6(21) = x(15)

41x = 61.5 ( divide both sides by 41 )

x = 1.5

substitute x = 1.5 into either of the 2 equations and solve for y

Answer:

Step-by-step explanation:

You want the solution to scalene triangle ABC with AC = 23, BC = 15, and ∠A = 40°.

When two sides of a triangle are given, along with an angle not between them, the Law of Sines can be used to solve the triangle. It tells you ...

  sin(B)/AC = sin(C)/AB = sin(A)/BC

When the given angle is opposite the shortest given side, there are generally 2 solutions.

  sin(B)/23 = sin(40°)/15 . . . . . fill in given values to find angle B

  B = arcsin(23/15·sin(40°)) = 80.3° or 99.7°

Angle C will have the value that makes up the difference from 180°:

  C = 180° -40° -{80.3°, 99.7°} = {59.7°, 40.3°}

The length of side AB can be found using the same Law of Sines proportion:

  AB = BC·sin(C)/sin(A) = 15/sin(40°)·sin({59.7°, 40.3°})

  AB = {20.2, 15.1}

The solutions are ...

Arguably, the second solution is not a "scalene" triangle. It is (nearly) isosceles. (See the comment below.)

Since answers are requested to be rounded to tenths, both solutions are scalene triangles. If we rounded to integers, then only the first solution would be a scalene triangle.
