A printer takes 7 minutes to print a document with 63 pages. How many pages
Artemon [7]

Create a proportion.

Since it takes 7 minutes to print 63 pages, and half an hour is 30 minutes, you create two ratios(unit per unit) and line up the units(minutes to minutes, pages to pages).

\frac{7 min}{63 pages} = \frac{30 min}{Xpages}

Now you cross multiply, 63 * 30 = 1890 and 7 * x = 7x.

So we have 1890 = 7x.

Then we divide both sides by seven.

\frac{1890}{7} = \frac{7x}{7}

270 = x, therefore you can print 270 pages in half an hour :)

Subjects for the next presidential election poll are contacted using telephone numbers in which the last four digits are randoml
sammy [17]

Answer:

probability at least one zero is 0.3439

Step-by-step explanation:

given data

last four digits = randomly selected​

to find out

probability that for one such phone​ number the last four digits include at least one 0.

solution

we know there are total 10 digit

so we first find probability of non zero digit i.e.

Probability  ( non zero ) = 9 /10 = 0.9

and now we find probability of none of digit zero  only event happen n= 4 time in a row by multiplication rules i.e

Probability ( none zero in 4 digit ) = 0.9^{n}

Probability ( none zero in 4 digit ) = 0.9^{4}

Probability ( none zero in 4 digit ) = 0.6561

so we can say probability at least one zero = 1 - Probability ( none zero in 4 digit )  

probability at least one zero = 1 - 0.6561

probability at least one zero is 0.3439

Answer: The answer to Number 4 is 1!

Step-by-step explanation:

First you solve for the numbers in parentheses. 16 - 7 is 9, and 2 x 4 is 8. Then you solve for the remaining numbers. So 9 - 8 is indeed 1.

Hope this helps! :)

Kate has an interior decorating business. She charges a base fee of $25 for each visit and $40 per hour for her labor. 1) Write
nataly862011 [7]

Answer:

1) C = $25 + $40 × h

2) The domain for the ≠unction is 0 ≤ h ≤ ∞

The range for the function is 25 ≤ C ≤ ∞

3) Continuous

Step-by-step explanation:

1) The given parameters are;

The base fee charged = $25

The amount charged for labor = $40/hour

The total cost for h number of hours is C = $25 + $40 × h

2) The domain for the ≠unction is 0 ≤ h ≤ ∞

The range for the function is 25 ≤ C ≤ ∞

3) The situation is continuous because the different input values of h can be infinite (from o to infinity)
