Answer:

Is there a reference? there's insufficient information.

Step-by-step explanation:

Using the t-distribution, it is found that the correct interpretation is:

b. Based on the sample data, with 90% confidence, the ISP can conclude that the true population mean daily usage time is between 297.75 minute(s) and 334.75 minute(s).

We can find the standard deviation for the sample, which is why the t-distribution is used to solve this question.

Using a calculator, we find that:

The confidence interval is:

[tex]\overline{x} \pm t\frac{s}{\sqrt{n}}[/tex]

The critical value, using a t-distribution calculator, for a two-tailed 90% confidence interval, with 12 - 1 = 11 df, is t = 1.7959.

Then:

[tex]\overline{x} - t\frac{s}{\sqrt{n}} = 316.25 - 1.7959\frac{35.68}{\sqrt{12}} = 297.75[/tex]

[tex]\overline{x} + t\frac{s}{\sqrt{n}} = 316.25 + 1.7959\frac{35.68}{\sqrt{12}} = 334.75[/tex]

From the confidence interval, we can infer about the population mean, hence, the correct option is:

b. Based on the sample data, with 90% confidence, the ISP can conclude that the true population mean daily usage time is between 297.75 minute(s) and 334.75 minute(s).

Answer:

I = $650

A = $23,580

Step-by-step explanation:

First question

I = ?, P = $1000, R= 5%, T = 13

[tex]I = \frac{P*R*T}{100}=\frac{1000*5*13}{100}= 650[/tex]

Therefore, interest = $650

Second...

P = $15, 000, R = 5.2%, T = 11, I = ? A= ?

[tex]I = \frac{P*R*T}{100}=\frac{15000*5.2*11}{100}= 8580[/tex]

To find A, we add the principal with the interest

A = P + I = $15,000 + $8580 = $23,580

The area wiped by the viper blade is approximately 486.7 square inches.

The area wiped by the wiper blade ([tex]A[/tex]), in square inches, is equal to the area of the circular section described below:

[tex]A = \frac{\theta\cdot \pi}{360}\cdot (R^{2}-r^{2})[/tex] (1)

Where:

If we know that [tex]\theta = 130^{\circ}[/tex], [tex]R = 25\,in[/tex] and [tex]r = 14\,in[/tex], then the area wiped by the wiper blade is:

[tex]A = \frac{130\pi}{360} \cdot [(25\,in)^{2}-(14\,in)^{2}][/tex]

[tex]A \approx 486.7\,in^{2}[/tex]

Answer:

3/2 is the slope and (0,5) is the y-intercept

Step-by-step explanation:

We need slope-intercept form for this question, so we simplify the equation into:

-2y=-10-3x which is just

y=5+3/2x =

y=3/2x+5

When we compare this to y=mx+b, we see that 3/2 is the slope and (0,5) is the y-intercept.

Answer: The slope is [tex]\frac{3}{2}[/tex] and the y-intercept is 5.

Step-by-step explanation:

The equation is 3x - 2y = -10

We need to turn 3x - 2y = -10 into slope intercept form.

y = mx + b → slope-intercept form

3x - 2y = -10

-3x           -3x

-2y = -3x - 10

Divide the whole equation by -2

y = [tex]\frac{3}{2}[/tex]x + 5

The slope of the equation is [tex]\frac{3}{2}[/tex] and the y-intercept is -2.

Step-by-step explanation:

If

[tex]\displaystyle g(x) = \int_0^x f(t) \, dt[/tex]

then g(x) gives the signed area under f(x) over a given interval starting at 0.

In particular,

[tex]\displaystyle g(0) = \int_0^0 f(t) \, dt = 0[/tex]

since the integral of any function over a single point is zero;

[tex]\displaystyle g(4) = \int_0^4 f(t) \, dt = 8[/tex]

since the area under f(x) over the interval [0, 4] is a right triangle with length and height 4, hence area 1/2 • 4 • 4 = 8;

[tex]\displaystyle g(8) = \int_0^8 f(t) \, dt = 0[/tex]

since the area over [4, 8] is the same as the area over [0, 4], but on the opposite side of the t-axis;

[tex]\displaystyle g(12) = \int_0^{12} f(t) \, dt = -8[/tex]

since the area over [8, 12] is the same as over [4, 8], but doesn't get canceled;

[tex]\displaystyle g(16) = \int_0^{16} f(t) \, dt = 0[/tex]

since the area over [12, 16] is the same as over [0, 4], and all together these four triangle areas cancel to zero;

[tex]\displaystyle g(20) = \int_0^{20} f(t) \, dt = 24[/tex]

since the area over [16, 20] is a trapezoid with "bases" 4 and 8, and "height" 4, hence area (4 + 8)/2 • 4 = 24;

[tex]\displaystyle g(24) = \int_0^{24} f(t) \, dt = 64[/tex]

since the area over [20, 24] is yet another trapezoid, but with bases 8 and 12, and height 4, hence area (8 + 12)/2 • 4 = 40, which we add to the previous area.
