Answer:

D =20 inches

Step-by-step explanation:

Given that,

A birthday cake is cut into 8 slices. The arc length of one piece is 8.0 inches.

We need to find the diameter of the cake.

The circumference of a circle is given by :

[tex]C=2\pi r[/tex]

ATQ,

[tex]\dfrac{1}{8}\times 2\pi r=8\\\\2r=\dfrac{64}{\pi}\\\\2r=20\ in[/tex]

Diameter, D = 2r

So, the diameter of the cake is equal to 20 inches.

Answer: Medians, Less

Part A

Use the measures of center from the box plots to make an inference about the data. Use the drop-down menus to explain your answer.

Based on the medians, the plants in Group A grew

less on average, as compared to the plants in Group B.

Part B Answer: Greater, Less

The range and IQR are greater

in Group B as compared to Group A, so there is less variability in the growth of plants in Group B.

Answer:

7

Step-by-step explanation:

perimeter - 7+7+7+7=28

area - 7×7 = 49

it's a square so all sides are the same length.

area is length times width

perimeter is all sides added together.

1/2 x 6 is the same as (1/2)*6

We multiply the fraction 1/2 by the whole number 6. We end up with 3.

If we had 6 slices of cake, and gave away half of that total, then we give away 3 slices.

6- yes

Step-by-step explanation:

Answer:

(a) A = 0.00278787878787878x

(b) B = 0.00235294117647058x + 3

(c) The answers are as follows:

For buying by credit card

For 700 BWP: Cost = A = £1.95

For 800 BWP: Cost = A = £2.23

For 800 BWP: Cost = A = £2.79

For buying from a Bureau de Change

The equation (4) is used as follows:

For 700 BWP: Cost = B = £4.65

For 800 BWP: Cost = B = $4.88

For 1000 BWP: Cost = B = £5.35

(d) You would have to buy 6,897.54 pulas for the cost to be the same whether you use a credit card or cash.

Step-by-step explanation:

(a) by credit card

For the exchange rate, we have:

8.25 BWP = £1 ⇒ 8.25 / 8.25 BWP = £1 / 8.25 = 1.00 BWP = £0.121212121212121

The expression can therefore be written as follows:

A = £0.121212121212121 * r * x ................. (1)

Where;

A = cost (including commission) of buying a particular number of Botswana pulas by credit card

r = commission on a credit card transaction = 2.3%, or 0.023

x = the number of pulas bought

Substituting for r into equation (1), we have:

A = £0.121212121212121 * 0.023 * x

A = 0.00278787878787878x ................. (2)

Equation (2) is the expression.

(b) from a Bureau de Change

For the exchange rate, we have

8.5 BWP = £1 ⇒ 8.5 / 8.5 BWP = £1 / 8.5 = 1.00 BWP = 0.117647058823529

B = (£0.117647058823529 * r * x) + F ................. (3)

Where;

B = cost (including commission) of buying a particular number of Botswana pulas by from a Bureau de Change.

r = commission charged by Bureau de Change. = 2%, or 0.02

x = the number of pulas bought

F = fee = £3

Substituting for r and F into equation (3), we have:

B = (£0.117647058823529 * 0.02 * x) + £3

B = 0.00235294117647058x + 3 ................. (4)

Equation (4) is the expression.

c. Evaluate each of these expressions for 700 BWP, 800 BWP, and 1000 BWP respectively.

For buying by credit card

The equation (2) is used as follows:

For 700 BWP: A = £0.00278787878787878 * 700 = £1.95

For 800 BWP: A = £0.00278787878787878 * 800 = £2.23

For 800 BWP: A = £0.00278787878787878 * 1000 = £2.79

For buying from a Bureau de Change

The equation (4) is used as follows:

For 700 BWP: B = (£0.00235294117647058 * 700) + £3 = £1.65 + £3 = £4.65

For 800 BWP: B = (£0.00235294117647058 * 800) + £3 = £1.88 + £3 = $4.88

For 1000 BWP: B = (£0.00235294117647058 * 1000) + £3 = £2.35 + £3 = £5.35

d. Hazard a guess as to the number of pulas you would have to buy for the cost to be the same whether you use a credit card or cash.

This can be calculated by equating equations (2) and (4) and then solve for x as follows:

0.00278787878787878x = 0.00235294117647058x + 3

0.00278787878787878x - 0.00235294117647058x = 3

x(0.00278787878787878 - 0.00235294117647058) = 3

x0.0004349376114082 = 3

x = 3 / 0.0004349376114082

x = 6,897.54 pulas

Therefore, you would have to buy 6,897.54 pulas for the cost to be the same whether you use a credit card or cash.

Answer:

102cm2

Step-by-step explanation:

Split the shape into two rectangles:

B. 7 x 10 = 70cm2

70 + 32 = 102cm2

Answer:

Disagree, as m is common to all terms of the expression and thus, can be factored. The factored expression is 7m(2 + 3p - 5q)

Step-by-step explanation:

If a variable is common to all terms of an expression, it can be factored.

14m + 21pm - 35mq

Here, m is common to all terms of the expression, so the factored expression is:

[tex]7m(\frac{14m}{7m} + \frac{21pm}{7m} - \frac{35mq}{7m}) = 7m(2 + 3p - 5q)[/tex]

Disagree, as m is common to all terms of the expression and thus, can be factored. The factored expression is 7m(2 + 3p - 5q)

Answer:

Answer:

The 99% confidence interval for p in this case is (0.3317, 0.5883).

Step-by-step explanation:

In a sample with a number n of people surveyed with a probability of a success of [tex]\pi[/tex], and a confidence level of [tex]1-\alpha[/tex], we have the following confidence interval of proportions.

[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

In which

z is the zscore that has a pvalue of [tex]1 - \frac{\alpha}{2}[/tex].

Randomly selects 100 students from the school and asks the President to name each one. The President is able to correctly name 46 of the students.

This means that:

[tex]n = 100, \pi = \frac{46}{100} = 0.46[/tex]

99% confidence level

So [tex]\alpha = 0.01[/tex], z is the value of Z that has a pvalue of [tex]1 - \frac{0.01}{2} = 0.995[/tex], so [tex]Z = 2.575[/tex].

The lower limit of this interval is:

[tex]\pi - z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.46 - 2.575\sqrt{\frac{0.46*0.54}{100}} = 0.3317[/tex]

The upper limit of this interval is:

[tex]\pi + z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.46 + 2.575\sqrt{\frac{0.46*0.54}{100}} = 0.5883[/tex]

The 99% confidence interval for p in this case is (0.3317, 0.5883).

[tex]\dfrac{4}{7}[/tex]

Step-by-step explanation:

A fraction can be written as :

[tex]F=\dfrac{x}{y}[/tex]

Where

x is numerator and y is denominator

We need to write a fraction for denominator 7 and numerator 4.

Substitute the values,

[tex]F=\dfrac{4}{7}[/tex]

Hence, the fraction is equal to [tex]\dfrac{4}{7}[/tex].

Answer:

35%

Step-by-step explanation:

Answer:

35%

Step-by-step explanation:

First, we must calculate how many seats are taken by 6th graders. We do this by subtracting the total seats by vacant seats. 3840-2496=1,334. Then, we must find the percent of students that were 6th grade who filled the seats. We do this by dividing all the chairs taken by the 6th graders and divide it by the total chairs which gets you .35. And with percentages, you move the decimal place two times to the right which gets you 35%.

Answer:

His total income is of $1,371.2.

Step-by-step explanation:

His salary is of $500, plus 8% of his sales.

In this question:

Sales of $10,890. So his salary is given by:

[tex]S = 500 + 0.08*10890 = 500 + 871.2 = 1371.2[/tex]

His total income is of $1,371.2.

Answer:

The answer is "0.18".

Step-by-step explanation:

Please find the complete question in the attached file.

We should always discover the chance of its driver becoming a female and driving between 10 and 20 minutes per hour:

[tex]\to P(female \cap \ 10- 20\ mph)[/tex] 

Its result is so good that it would be women, plus 10-20 mph (it would also be 9 intersections), chosen from the 50 total drivers

So, probability required [tex]= \frac{9}{50} = 0.18[/tex]
