Huong collects coins. Over a three-year period she collected 1,000 nickels. After organizing them by year, she found that the nu

mber of nickels from a given year was related to the number minted that year:
minted (100 mill) | 3.3 | 7.8 | 11.8 | 12.6 | 15.1 | 16.4 |

In sample | 3 | 19 | 27 | 24 | 30 | 43 |

a.) Logarithmic
b.)exponential
c.)linear
d.)quadratic

Answer:

C.) Linear

Step-by-step explanation:

The line of best fit is a straight line.

Linear also make sense because the more nickles minted in a year, the more chance for a nickle to be from that year.

Pizza Paradise offers 4 types of crust, 10 toppings, and 8 kinds of cheese for the mega calzone. How many different mega calzone

Bumek [7]

Answer:

26880 ways

<em></em>

Step-by-step explanation:

Given

$Crust = 4$

$Toppings = 10$

$Cheese = 8$

Required

Determine the number of ways 3 toppings and 3 cheese can be selected

The number of crusts to be selected was not stated. So, I'll assume 1 crust to be selected from 4.

This can be done in $^4C_1$ ways

For the toppings:

3 can be selected from 10 in $^{10}C_3$ ways

For the cheeses:

3 can be selected from 8 in $^{8}C_3$ ways

Total number of selection is:

$Total = ^4C_1 * ^{10}C_3 * ^{8}C_3$

Apply combination formula:

$Total = \frac{4!}{(4-1)!1!} * \frac{10!}{(10-3)!3!} * \frac{8!}{(8-3)!3!}$

$Total = \frac{4!}{3!1!} * \frac{10!}{7!3!} * \frac{8!}{5!3!}$

$Total = \frac{4*3!}{3!*1} * \frac{10*9*8*7!}{7!*3*2*1} * \frac{8*7*6*5!}{5!*3*2*1}$

$Total = \frac{4}{1} * \frac{10*9*8}{3*2*1} * \frac{8*7*6}{3*2*1}$

$Total = 4 * \frac{720}{6} * \frac{336}{6}$

$Total = 4 * 120* 56$

$Total = 26880$

<em>Hence, there are 26880 ways</em>

Help with this math picture :) worth 8 points

Solving for x...
$\frac{1}{2} x+ \frac{1}{4} = \frac{15}{16} 
$

Times the $\frac{1}{2}$ , both the numerator and denominator, by 8 to get the denominator to 16.
Times the $\frac{1}{4}$ , both the numerator and denominator, by 4 to get the denominator to 16.

Then rewrite the problem,
$\frac{8}{16}x+ \frac{4}{16} = \frac{15}{16}$

now that the denominators are all the same, you can solve...
subtract the $\frac{4}{16}$ from both sides

you should get $\frac{8}{16} x = \frac{11}{16}$

Multiply both sides by 16 (it'll cancel both the 16 out making it go away)
8x = 11

divide each side by 8 to have the x alone

<u>8x</u> = <u>11
</u> 8 8
<u>
</u> You should end with x = $\frac{11}{8}$ or 1.375<u>
</u>

Use the above figure to answer the question. How long is arc ACB if the radius of the circle is 6? Round your answer to two deci

Svet_ta [14]

After a thorough research, there exists the same question that has the following choices.

A. 6.29
<span>B. 12.57
</span><span>C. 18.86
</span><span>D. 25.13</span>

The correct answer is letter B 12. 57
First, we need to get the circumference
C = 2*pi*r
C = 12 pi
360/ 60+60 = 360/120 = 3
12 pi / 3 = 4 pi = 4 x 3.1415 = 12.57
