Answer:

  • 6.045×10^40 ergs
  • 1.8×10^-2 mm

Step-by-step explanation:

A) Your scientific or graphing calculator can tell you the product:

  (3.9×10^33 erg/s)(1.55×10^7 s) = 6.045×10^40 ergs

__

B) 10^2 mm is 100 mm, about 4 inches, so 1.8×10^2 mm is about 7 inches. This is somewhat larger than the diameter of a human hair (and about the same size as the diameter of a human <em>head</em>).

1.8×10^-2 mm = 18 μm is a more reasonable estimate of hair diameter

(The range of hair diameters is reportedly about 17 to 181 μm, so the given dimension is on the low end.)

Tickets to the college basketball game are $2.50 for students and $3 for general admission. If 54 people attended the last game
Yuki888 [10]

Answer:

  • 28 general admission
  • 26 student

Step-by-step explanation:

Let g represent the number of general admission tickets sold. Then the revenue is ...

  3g +2.50(54-g) = 149

  .50g = 14 . . . . . . . . . . . subtract 135

  g = 14/.5 = 28 . . general admission tickets sold

  54-g = 26 . . . . . student tickets sold

Ten college students were randomly selected. Their grade point averages​ (GPAs) when they entered the program were between 3.5 a
solong [7]

Answer:

The 95% confidence interval for the true slope is (0.03985, 0.14206).

Step-by-step explanation:

For the regression equation:

\hat y=\alpha +\hat \beta x

The (1 - <em>α</em>)% confidence interval for the regression coefficient or slope (\hat \beta ) is:

Ci=\hat \beta \pm t_{\alpha/2, (n-2)}\times SE(\hat \beta )

The regression equation for current GPA (Y) of students based on their GPA's when entering the program (X) is:

\hat Y=3.584756+0.090953 X

The summary of the regression analysis is:

Predictor          Coefficient             SE             t-stat            p-value

Constant             3.584756          0.078183       45.85075      5.66 x 10⁻¹¹

Entering GPA   0.090953          0.022162        4.103932       0.003419

The regression coefficient and standard error are:

\hat \beta = 0.090953\\SE (\hat \beta)=0.022162

The critical value of <em>t</em>  for 95% confidence level and 8 degrees of freedom is:

t_{\alpha/2, n-2}=t_{0.05/2, 10-2}=t_{0.025, 8}=2.306

Compute the 95% confidence interval for (\hat \beta ) as follows:

CI=\hat \beta \pm t_{\alpha/2, (n-2)}\times SE(\hat \beta )\\=0.090953\pm 2.306\times 0.022162\\=0.090953\pm 0.051105572\\=(0.039847428, 0.142058572)\\\approx (0.03985, 0.14206)

Thus, the 95% confidence interval for the true slope is (0.03985, 0.14206).
