A customer would  be charged $ 52 for an international phone call that started at 9:35 p.m. and ended at 11:15 p.m. the same day.

Charge for first 5 charged = $ 4.50

Charge for additional time = $ 0.50 per minute

Starting time = 9:35 p.m.

End time = 11:15 p.m.

Total minutes = 100 minutes

Total charge = 4.50 + (95 x 0.50)

                  = 4.50 + 47.50

                  = 52.00

Hence, a customer would  be charged $ 52 for an international phone call that started at 9:35 p.m. and ended at 11:15 p.m. the same day i.e. for 100 minutes.

At the hot wings restaurant, a fraction of 5/9 of the patrons ordered the inferno hot wings, and 1/8 of those patrons passed out from the intensity of the sauce. The fraction of patrons who passed out are 5/72.

Given that 5/9 of the patrons ordered the inferno hot wings, this fraction represents the portion of patrons who were exposed to the intense sauce. Out of this group, 1/8 passed out due to the sauce's intensity.

To find the fraction of patrons who passed out, we multiply the fractions 5/9 and 1/8:

(5/9) * (1/8) = 5/72.

Therefore, the fraction 5/72 represents the proportion of patrons who passed out from the intensity of the inferno hot wing sauce.

This information is important for understanding the effects of the spicy sauce and can be used by the restaurant to gauge the intensity of the dish and potentially make adjustments to cater to different preferences. Additionally, it provides insights into the customer experience and can influence future menu decisions or considerations regarding the heat levels of their offerings.

Answer:

B. 63°

Step-by-step explanation:

The distance around a circle is 360°

This means that 297° + n = 360°

Equation:

297 + n = 360

We can find the value of n by subtracting:

297 + n = 360

-297        -297

n = 63

Therefore, the value of n is 63 degrees.

The surface area of the softball is approximately 254.34 square centimeters.

To calculate the surface area of a softball, we can use the formula for the surface area of a sphere, which is S.A. = 4πr².

Given that the diameter of the softball is 9 cm, we can find the radius (r) by dividing the diameter by 2:

r = 9 cm / 2 = 4.5 cm

Now we can substitute the value of the radius into the surface area formula:

S.A. = 4π(4.5 cm)²

Simplifying further:

S.A. = 4π(20.25 cm²)

S.A. = 81π cm²

To calculate the numerical value, we can use an approximation for π, such as 3.14:

S.A. ≈ 81 * 3.14 cm²

S.A. ≈ 254.34 cm²

It's important to note that the result is an approximation due to using an approximation for π. Using more decimal places for π would yield a more precise value.

The y-intercept of the equation is 4.

The equation of a line is

y = mx + c

x, y is the point on the line

m = slope of a line

c = y-intercept

As the equation of a line is 3x + 2y = 8.

We have to find the y-intercept of the equation.

3x + 2y = 8

2y = -3x + 8

y = -3/2x + 4

y = mx + c

So from this, we get the y-intercept

c = 4

Therefore the y-intercept of the equation is 4.

Answer:

<AEB = 51.2

Step-by-step explanation:

Remark

A straight line has a degree value of 180. There are 3 angles. One of them is 90. The other two must add to 90

Equation

2.7x + 8 + 3.8x - 22 = 90      combine like terms on the left.

6.5x - 14 = 90                        add 14 to both sides

6.5x = 90 + 14

6.5x = 104                              Divide by 6.5

x = 104/6.5

x = 16

Answer:

At the end of ten days, the size of population B is 256 times that of population A

Step-by-step explanation:

We work under the premise that population A and B start both with the same number of individuals. Let's call such initial population \(N_0\)

Now, we write the exponential expression that describes population A as a function of days (t) for the first 6 days:

\(N_A=N_0\,(2)^t\)

which represents the starting point with \(N_0\) individuals on day zero, doubling after one day (t= 1), and keeping on doubling the following days for 6 days.

So at the end of 6 days, population A would have the following number of individuals:

\(N_A=N_0\,(2)^6\\N_A=N_0\,(64)\\N_A=64\,N_0\)

That is 64 times the starting number of individuals.

After this, the population stops growing and starts reducing to one-half each day. This behavior can be represented by:

\(N_A=64\,N_0\,(\frac{1}{2} )^t\)

therefore after 4 days in this pattern, this culture has the following number of organisms:

\(N_A=64\,N_0\,(\frac{1}{2} )^4\\N_A=64\,N_0\,(\frac{1}{16} )\\N_A=4\,N_0\)

which is now just four times what the culture started with.

Now, on the other hand, population B grows doubling each day without interruption, so at the end of 10 days its size is given by:

\(N_B=N_0\,(2)^t\\N_B=N_0\,(2)^10\\N_B=N_0\1024\\N_B=1024\,N_0\)

that is it has 1024 times the initial number of organisms.

So if we compare both populations at day 10:

\(\frac{N_B}{N_A} =\frac{1024\/N_0}{4\,N_0} =256\)

Therefore, at the end of ten days, population B is 256 times the size of population A

Answer:

After 10 days, population B has grown to be 256 times the size of population A.

The decision for this test at a .05 level of significance is not enough information to make a decision the correct answer is (d).

To make a decision for a hypothesis test, we compare the obtained test statistic (in this case, z = 1.80) with the critical value(s) based on the chosen level of significance (in this case, α = 0.05).

For a one-sample z test, if the obtained test statistic falls in the rejection region (i.e., beyond the critical value(s)), we reject the null hypothesis. Otherwise, if the obtained test statistic does not fall in the rejection region, we fail to reject the null hypothesis.

Without knowing the critical value(s) corresponding to a significance level of 0.05 and the directionality of the test (one-tailed or two-tailed), we cannot determine the decision for this test. Therefore, the correct answer is (d) There is not enough information to make a decision.

The implicit solution of the given differential equation is |y - 4| = e^[(x³ / 3) + C] and the equation using x and y as the variables is y = 4 ± 2e^(x³ / 3).

The given initial value problem is dy/dx = x²(y - 4), y(0) = 6

We need to find the implicit solution and also an equation using x and y as the variables.

We can use the method of separation of variables to solve the given differential equation.

dy / (y - 4) = x² dx

Now, we can integrate both sides.∫dy / (y - 4) = ∫x² dxln|y - 4| = (x³ / 3) + C

where C is the constant of integration.

Now, solving for y, we get|y - 4| = e^[(x³ / 3) + C]y - 4 = ±e^[(x³ / 3) + C]y = 4 ± e^[(x³ / 3) + C] ... (1)

This is the implicit solution of the given differential equation.

Now, using the initial condition, y(0) = 6, we can find the value of C.

Substituting x = 0 and y = 6 in equation (1), we get

6 = 4 ± e^C => e^C = 2 and C = ln 2

Substituting C = ln 2 in equation (1), we gety = 4 ± e^[(x³ / 3) + ln 2]y = 4 ± 2e^(x³ / 3)

This is the required equation using x and y as the variables.

Answer: The implicit solution of the given differential equation is |y - 4| = e^[(x³ / 3) + C] and the equation using x and y as the variables is y = 4 ± 2e^(x³ / 3).

The appropriate statistical technique to compare money spent at the store between two groups in a marketing research study is the independent-samples t-test.

The independent-samples t-test is used to compare the means of two independent groups. In this case, the groups are the ones who received the coupon and the ones who did not, and they are independent because the participants were randomly assigned to each group.

The null hypothesis for the independent-samples t-test is that there is no difference between the means of the two groups. The alternative hypothesis is that there is a significant difference between the means of the two groups.

By conducting an independent-samples t-test on the data, the researcher can determine whether the difference in money spent at the store between the two groups is statistically significant or simply due to chance. If the p-value is less than the significance level (usually 0.05), the researcher can reject the null hypothesis and conclude that there is a significant difference between the two groups in terms of the money spent at the store.

Therefore, the independent-samples t-test is an appropriate statistical technique to compare the means of two independent groups and test for significant differences between them.

Step-by-step explanation:

\(\left(\dfrac{}{}(-3)^2\dfrac{}{}\right)^{-3}\)

First, we should evaluate inside the large parentheses:

\((-3)^2 = (-3)\cdot (-3) = 9\)

We know that a number to a positive exponent is equal to the base number multiplied by itself as many times as the exponent. For example,

\(4^3 = 4 \, \cdot\, 4\, \cdot \,4\)

       ↑1 ↑2 ↑3 times because the exponent is 3

Next, we can put the value 9 into where \((-3)^2\) was originally:

\((9)^{-3}\)

We know that a number to a negative power is equal to 1 divided by that number to the absolute value of that negative power. For example,

\(3^{-2} = \dfrac{1}{3^2} = \dfrac{1}{3\cdot 3} = \dfrac{1}{9}\)

Finally, we can apply this principle to the \(9^{-3}\):

\(9^{-3} = \dfrac{1}{9^3} = \boxed{\dfrac{1}{729}}\)

The range interval is: (7, -1)

Step-by-step explanation:

Given the function

g(x) = -2r+5

Let us put the domain values in the interval (-1, 3)

Putting x = -1

g(x)=-2r+5

      = -2(-1)+5

      = 2+5

      = 7

Putting x = 0

g(x)=-2r+5

      = -2(0)+5

      =0+5

      = 5

Putting x = 1

g(x)=-2r+5

      = -2(1)+5

      =-2+5

      = 3

Putting x = 2

g(x)=-2r+5

      = -2(2)+5

      =-4+5

Line a and line b intersect to form four right angles.

Step-by-step explanation:

Given

Perpendicular lines a and b

Required

Select the true statements

Represent the slope of line a with \(m_1\) and the slope of b with \(m_2\).

The condition for perpendicularity is:

\(m_1 * m_2 = -1\)

Solving further:

\(m_1 = -\frac{1}{m_2}\)

To solve further, we need to analyze each of the given options

(a) This is not true because the slope of perpendicular lines are not reciprocal

(b) This is also not true because perpendicular lines do not necessarily have to intersect at their midpoints

(c) This is true because of the condition stated above: \(m_1 * m_2 = -1\)

(d) This is also true because perpendicular lines form right angles when they intersect

(e) This is not true because of the condition stated above: \(m_1 = -\frac{1}{m_2}\)

(f) This is not true because of the condition stated above: \(m_1 = -\frac{1}{m_2}\)

The product of the slope of the perpendicular lines is negative of one. Then the correct options are B and C.

It is a system of an equation in which the highest power of the variable is always 1. A one-dimension figure that has no width. It is a combination of infinite points side by side.

Lines a and b are perpendicular.

Then the product of the slope of the perpendicular lines is negative of one. That is given as
