Answer:

Downloading 28 songs will cost $26.64.

Step-by-step explanation:

Given that a brand-new music service is offering specials on individual song downloads, and the cost is $ 0.74 for each song up to 20 songs per month, and the cost doubles to $ 1.48 per download for any number of downloads over 20, to determine how much would it cost to download 28 songs the following calculation should be performed:

(20 x 0.74) + (8 x 1.48) = X

14.8 + 11.84 = X

26.64 = X

Therefore, downloading 28 songs will cost $ 26.64.

The value of x is -0.22.

The power to which a number must be increased in order to obtain another number is known as a logarithm.

How many times must one "base" number be multiplied by itself in order to generate another specific number? The answer is found using a logarithm (or log).

Given:

[tex]e^x[/tex] = 0.6

Now, taking log on both side

x log e= log 0.6

x= -0.22184874961

Hence, the value of x is -0.22.

Answer:

Number of year = 11.725 year (Approx.)

Step-by-step explanation:

Given:

Amount invested = $200

Interest rate = 6% (compounded semi annually)

Future value = 2 x Amount invested

Find:

Number of year

Commutation:

Future value = 2 x Amount invested

Future value = 2 x 200

Future value = $400

Number of year (Semi-annual) = 2n

Interest rate (Semi-annual) = 6% / 2 = 3%

So.

A = P[1+r]ⁿ

400 = 200[1+3%]²ⁿ

2 = [1.03]²ⁿ

n = 11.725 year

Number of year = 11.725 year (Approx.)

Answer:

m(arc AC) = 72°

m(arc BD) = 108°

m∠DEB = 90°

Step-by-step explanation:

Ratio of the measure of arc AC, arc BC, arc BD and arc AD = 4 : 2 : 6 : 8

Since, m(arc AC) + m(arc CB) + m(arc BD) + m(arc AD) = 360°

By the property of ratio,

Measure of arc AC = [tex]\frac{4}{4+2+6+8}\times (360^0)[/tex]

                               = [tex]\frac{4\times 360}{20}[/tex]

                               = 72°

Measure of arc BD = [tex]\frac{6}{4+2+6+8}\times (360^0)[/tex]

                               = [tex]\frac{6\times 360}{20}[/tex]

                               = 108°

Measure of ∠DEB = [tex]\frac{1}{2}m(arcAC + arc BD)[/tex]

                              = [tex]\frac{1}{2}(72+108)[/tex]

                              = 90°

There are 48 oz in 3 pounds, or 16 oz in a pound. Now divide the oz by the equal sizes

48/8=6

Answer:

B) f = (6 x 8) + 4

Step-by-step explanation:

Remember this: 1 cup = 8 fl oz

They're asking for the total number of fluid ounces of detergent, and we're given 6 cups and 4 fl oz.

Set up a proportion to find the total number of fl oz from the 6 cups, let variable x be the total oz of the 6 cups:

[tex]\frac{1 cup}{8 oz} = \frac{6 cups}{x oz}[/tex]

The answer should be 48 fl oz, then you add the 4 fl oz to have the total of 52 fl oz.

Answer:

The volume of the composite figure is approximately 434.041 cubic centimeters.

Step-by-step explanation:

The volume of the composite figure ([tex]V[/tex]), in cubic centimeters, is the sum of the volumes of the cuboid ([tex]V_{c}[/tex]), in cubic centimeters, and hemisphere ([tex]V_{h}[/tex]), in cubic centimeters, that is:

[tex]V = V_{c} + V_{h}[/tex] (1)

[tex]V = w\cdot h \cdot l + \frac{2\pi}{3}\cdot R^{3}[/tex] (2)

Where:

[tex]w[/tex] - Width, in centimeters.

[tex]h[/tex] - Height, in centimeters.

[tex]l[/tex] - Length, in centimeters.

[tex]R[/tex] - Radius, in centimeters.

If we know that [tex]w = 10\,cm[/tex], [tex]h = 6\,cm[/tex], [tex]l = 5\,cm[/tex] and [tex]R = 4\,cm[/tex], then the volume of the composite figure is:

[tex]V = w\cdot h \cdot l + \frac{2\pi}{3}\cdot R^{3}[/tex]

[tex]V = (10\,cm)\cdot (6\,cm)\cdot (5\,cm) + \frac{2\pi}{3}\cdot (4\,cm)^{3}[/tex]

[tex]V \approx 434.041\,cm^{3}[/tex]

The volume of the composite figure is approximately 434.041 cubic centimeters.

Answer:

The 80% confidence interval for the population proportion of disks which are defective is (0.059, 0.079).

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].

Suppose a sample of 1067 floppy disks is drawn. Of these disks, 74 were defective.

This means that [tex]n = 1067, \pi = \frac{74}{1067} = 0.069[/tex]

80% confidence level

So [tex]\alpha = 0.2[/tex], z is the value of Z that has a pvalue of [tex]1 - \frac{0.2}{2} = 0.9[/tex], so [tex]Z = 1.28[/tex].

The lower limit of this interval is:

[tex]\pi - z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.069 - 1.28\sqrt{\frac{0.069*0.931}{1067}} = 0.059[/tex]

The upper limit of this interval is:

[tex]\pi + z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.069 + 1.28\sqrt{\frac{0.069*0.931}{1067}} = 0.079[/tex]

The 80% confidence interval for the population proportion of disks which are defective is (0.059, 0.079).
