In the given question there are certain information’s based on which the answer to the question can be easily reached.
Let us assume that the distance ran by Adam = x
The the distance ran by Julio = (x - 17) miles
It is also given that Julio had run 13 miles
The we can create an equation and that is
x - 17 = 13
x = 13 + 17
  = 30
So Adam ran a distance of 30 miles.

Triangle FGH is similar to JKM.
mario62 [17]

Answer: J = 14.4 cm

Step-by-step explanation:

<em>K is similar to G</em>

So we can find the scale that FHG was dilated by dividing the side length of G by the side length of K

16.56/9.2 = 1.8

So the sides of the triangle KMJ were multiplied by a factor of 1.8

to find m :

25.92/1.8 = 14.4

J = 14.4

Jackson has three cartons of gumballs. There are 100 boxes in each carton. There are 100 gumballs in each box
lilavasa [31]

Answer:

3. 10000

Step-by-step explanation:

Given the following :

Number of gumball cartons = 3

Number of boxes per carton = 100

Number of gumballs per box = 100

The number of gumballs can be expressed in the form : (a. 10) ; where ; a = prime number ; b = whole number

Values of a and b?

Total number of gumballs :

Number of carton × number of boxes per carton × number of gumballs per box

3 × 100 × 100

Hence, writing the expression in the form: a. 10

a. 10 = 3 × 10000

An air transport association surveys business travelers to develop quality ratings for transatlantic gateway airports. The maxim
Flura [38]

Answer:

The 95% confidence interval estimate of the population mean rating for Miami is (6.0, 7.5).

Step-by-step explanation:

The (1 - <em>α</em>)% confidence interval for the population mean, when the population standard deviation is not provided is:

CI=\bar x \pm t_{\alpha/2, (n-1)}\cdot \frac{s}{\sqrt{n}}

The sample selected is of size, <em>n</em> = 50.

The critical value of <em>t</em> for 95% confidence level and (<em>n</em> - 1) = 49 degrees of freedom is:

t_{\alpha/2, (n-1)}=t_{0.05/2, 49}\approx t_{0.025, 60}=2.000

*Use a <em>t</em>-table.

Compute the sample mean and sample standard deviation as follows:

\bar x=\frac{1}{n}\sum X=\frac{1}{50}\times [1+5+6+...+10]=6.76\\\\s=\sqrt{\frac{1}{n-1}\sum (x-\bar x)^{2}}=\sqrt{\frac{1}{49}\times 31.12}=2.552

Compute the 95% confidence interval estimate of the population mean rating for Miami as follows:

CI=\bar x \pm t_{\alpha/2, (n-1)}\cdot \frac{s}{\sqrt{n}}

     =6.76\pm 2.000\times \frac{2.552}{\sqrt{50}}\\\\=6.76\pm 0.722\\\\=(6.038, 7.482)\\\\\approx (6.0, 7.5)

Thus, the 95% confidence interval estimate of the population mean rating for Miami is (6.0, 7.5).
