a number is less than 15

Answer:

For 130 non-fiction books, the number of fiction books can be from 270 to 278.

Step-by-step explanation:

Given that, there are 5 non-fiction books for every 9 fiction books.

Observe that, if the number of fiction books is less than 9, than there will be no no-fiction books.

So, there are 5 non-fiction books for every 9 to (9+8) fiction books

So, by elementary method, there will be 5n non-fiction books for every 9n+8 fiction books, where n is a natural number.

Or, if the number of non-fiction books is 5n, then the number of fiction books will be ranging from 9n to (9n+8).

For, 150 non-fiction books, 5n=150 or n=150/5=30.

Hence, the number of fiction books can be from 9n to (9n+8).

=9x30 to (9x30+8)

=270 to 278.

Hence, for 130 non-fiction books, the number of fiction books can be from 270 to 278.

A correct option is option (c).

The given point is (6,-3).

Reflection of the point:

When a point is reflected across the X-axis, the x-coordinates remain the same. But the Y-coordinates are transformed into their opposite signs.

Therefore, the reflection of the point (x, y) across the X-axis is (x, -y).

So, the reflection of the given point over the x-axis is,

[tex](6,-(-3)=(6,3)[/tex]

A correct option is option (c).

64 cubic feet cause you add them all together

Answer:

a. [tex]\$3107[/tex]

b. 17 years

c. The amount that is currently charged by the college you attend is much higher than the amount charged in two-year college in the present year.

Step-by-step explanation:

a.

[tex]f(x)=64x+2083[/tex]

Here, x is a the number of years after 2000 and f(x) is the total cost.

To approximate the yearly cost of  attending a two-year college in the year 2016,  find [tex]f(16)[/tex].

[tex]f(16)=64(16)+2083\\\\=1024+2083\\\\=\$3107[/tex]

b.

To predict in what year the yearly  cost of tuition and required fees will exceed $3200, solve [tex]f(x)=3200[/tex]

[tex]64x+2083=3200\\\\64x=3200-2083\\\\=1117\\x=\frac{1117}{64}\\\\ =17.45[/tex]

So,

x is approximately equal to 17 years.

c.

The present year is 2020.

To approximate the yearly cost of  attending a two-year college in the present year, find [tex]f(20)[/tex]

[tex]f(20)=64(20)+2083\\\\=1280+2083\\\\=\$3363[/tex]

The amount that is currently charged by the college you attend is much higher than the amount charged in two-year college in the present year.

Answer:

The chance of getting a sample  proportion of 70% or greater is 0.026.

Step-by-step explanation:

We are given that a poll shows that 50% of students play sports .

A random sample of 20 students showed that  70% of them play sports.

Let [tex]\hat p[/tex] = sample proportion of students who play sports

The z-score probability distribution for the sample proportion is given by;

                           Z  =  [tex]\frac{\hat p-p}{\sqrt{\frac{\hat p(1-\hat p)}{n} } }[/tex]  ~ N(0,1)

where, [tex]\hat p[/tex] = sample proportion of students who play sports = 70%

           p = population proportion of students who play sports = 50%

           n = sample of students = 20

Now, the chance of getting a sample  proportion of 70% or greater is given by = P([tex]\hat p[/tex] [tex]\geq[/tex] 70%)

   P([tex]\hat p[/tex] [tex]\geq[/tex] 70%) = P( [tex]\frac{\hat p-p}{\sqrt{\frac{\hat p(1-\hat p)}{n} } }[/tex] [tex]\geq[/tex] [tex]\frac{0.70-0.50}{\sqrt{\frac{0.70(1-0.70)}{20} } }[/tex] ) = P(Z [tex]\geq[/tex] 1.95) = 1 - P(Z < 1.95)

                                                                 = 1 - 0.97441 = 0.026

The above probability is calculated by looking at the value of x = 1.95 in the z-table which has an area of 0.97441.

Hence, the chance of getting a sample  proportion of 70% or greater is 0.026.

Step-by-step explanation:

Let Mt Rainer be X.

Let Mt KcKinley be X+5,910.

So,   X + (X + 5,910) = 34,730

Combine the variables and,   2X + 5,910 = 34,730

Subtract 5,910 from both sides and,    2X = 28,820

Divide both sides by 2 and,   X = 14,410

So, Mt Rainer is 14,410 and Mt McKinley is (14,410 + 5,910) = 20,320

Answer:

Mount McKinley = 34,730

Mount Rainier = 28,820

Step-by-step explanation:

Step 1:

x + 5,910 = 34,730   Equation

Step 2:

x = 34,730 - 5,910   Subtract 5,910 on both sides

Step 3:

x = 28,820

Step 4:

28,820 + 5,910

Answer:

Mount McKinley = 34,730

Mount Rainier = 28,820
