A median is the middle number of a data set.
To find it put the numbers in order.
9, 10, 10, 11, 12, 13, 13, 14, 14, 14, 16, 16
Then find the middle number
9, 10, 10, 11, 12, 13, 13, 14, 14, 14, 16, 16

The median is 13

A mode is a number that appears the most.
9, 10, 10, 11, 12, 13, 13, 14, 14, 14, 16, 16

The mode is 14

Hope this helped! If you have anymore questions or don't understand, please comment on my profile or DM me. :)

Janette has 386 pennies. 58 nickels and 19 dimes If Janette exchanges her coins for dollars, how many dollars will she have? Ho

Answer:

$8 ; 66 cents

Step-by-step explanation:

Given that:

Worth of penny, dimes and Nickel in cents and dollars

Nickel, n = 5 cents = $0.05

Dimes, d = 10 cent = $0.1

Penny, p = 1 cent = $0.01

Multiplying the number of each coin with its respective value ;

386(0.01) + 58(0.05) + 19(0.1)

$3.86 + $2.9 + $1.9

= $8.66

Changing it to dollar ,

$8.66 dollars = 8 dollars ;

$0.66 = 66 cents

When we want to find the roots of a one-variable function, we look for where its graph intersects the x-axis. In this case, the graph intersects the x-axis at $x=1.$

The vertex of a parabola is the highest or lowest point on it, depending on whether the leading coefficient of the quadratic function is negative or positive. In this case, we see that the lowest point is $(1,0).$

For the y-intercept, just look for where the graph intersects the y-axis; in this case, that point is $(0,1).$

Using this information, the vertex-form equation of the parabola is $y=1\cdot(x-1)^2+0,$ so the factors are two copies of $x-1.$ In this case, the value of $a$ in the equation $y=a(x-h)^2+k$ was conveniently 1; if that's not the case, you'll want to plug in $x=0$ to solve for the value of a that gives the correct y-intercept.
