Answer:

Step-by-step explanation:

this asks for the median, and not the mean value.

please notice that these 2 values are often if not mostly different from each other.

the median just defines the middle of the value interval, so that half of the different values are left, and half are right of that median value.

here we have 7 values. do we find one, so that 3 other values are smaller, and 3 other values are bigger than that ?

that is 15.

10, 12, 13 are smaller.

16, 19 and 25 are bigger.

so, 15 is the median.

Answer:

1 oz of chips has 120mg of sodium, while in 1 cup of soda there are 50mg of sodium.

Step-by-step explanation:

This question can be solved by a system of equations.

I am going to say that:

x is the number of mg of sodium in 1 oz of chips.

y is the number of mg of sodium in a cup of soda.

Bryan ate 5 oz of chips and drank 1 cup of soda for a total of 650 mg of sodium.

This means that:

$5x + y = 650$

Jadyn ate 1 oz of chips and drank 5 cups of soda for a total of 250 mg of sodium.

This means that:

$x + 5y = 250$

From the first equation:

$y = 650 - 5x$

Replacing in the second

$x + 5(650 - 5x) = 250$

$x + 3250 - 25x = 250$

$25x = 3000$

$x = \frac{3000}{25}$

$x = 120$

$y = 650 - 5x = 650 - 5*120 = 650 - 600 = 50$

1 oz of chips has 120mg of sodium, while in 1 cup of soda there are 50mg of sodium.

You can helps me? <br>f(x) = x + 20 <br>g(x) = x + 5 <br>(f o g) (2) = ?

pav-90 [236]

<h2>♪Answer : </h2>

f(x) = x + 20
g(x) = x + 5

»(f o g)(2)

find (f o g)(x)

»f(g(x))

»f(x + 5)

»x + 5 + 20

»x + 25

so, (f o g)(2) is

»2 + 25

Answer:

$4 = (x + 7 {)}^{2} + (y - 3 {)}^{2}$

Step-by-step explanation:

equation of a circle

${r}^{2} = (x - {h} )^{2} + (y - {k)}^{2}$

we know the center is (-7, 3)

the radius is 2

we replace (h,k) with the center coordinates

and input the radius

${2}^{2} = (x -( - 7)) ^{2} + (y - 3)^{2}$

simplify to this:

$4 = (x + 7 {)}^{2} + (y - 3 {)}^{2}$
