The median for the given set of six ordered values is 28.5

1 answer:

6 0

X=the missing value

the median is the middle number, but in this case there are two which happens to be 25 and x
so the formula is

25+x/2=31.5
use algebra to solve
25+x=63
x=63-25
x= 38

Therefore, the missing value is 38.

Hope this helped. Let me know if you have any further questions:)

Find the axis of symmetry: <br> Y=4x^2+16x-2

irinina [24]

Do this by converting to vertex form

y = 4x^2 + 16x - 2

y = 4 (x^2 + 4x - 0.5) completing the square on x^2 + 4x:-

y = 4[(x + 2)^2 - 4.5]

the axis of symmetry is x = -2

A snail travels at a rate of 2.35 feet per minute. . • Write a rule to describe the function.. • How far will the snail travel i

Vlad1618 [11]

Answer:

s(t) = 2.35t and distance covered in 5 minutes = 11.75 feet.

Step-by-step explanation:

A snail travels at a rate of 2.35 feet per minute.

We have to write a rule to describe the function.

If a snail covers the distance of 2.35 feet in a minute then in t minutes distance traveled by the snail will be = 2.35×(t) feet

Now if we define the distance as a function then function will be

S(t) = 2.35(t)

and distance covered by the snail in 5 minutes will be

Distance = 2.35×5 = 11.75 feet

Therefore the function is S(t) = 2.35t and distance covered in 5 minutes is 11.75 feet.

a local specialty delivery service charges a fee of $7 for each delivery plus. 45 cents for each mile over 10 miles. what variab

julia-pushkina [17]

Answer: Independent variable = number of miles he drive over 10 miles

Dependent variable = Total fee (in dollars)

Step-by-step explanation:

Given : Charge for each delivery = $7

Addition charge for each mile over 10 miles = 45 cents = $0.45

[ 1 cent = $ 0.01 ]

Since the fee vary by the number of miles he drive over 10 miles.

So , Independent variable = number of miles he drive over 10 miles

Dependent variable = Total fee (in dollars)

Let x= number of miles he drive over 10 miles

y= Total fee (in dollars)

Such that , $y= 7+0.45x$ [Total fee= Fixed charge + Additional charge ]

So , the appropriate variables are:

Independent variable = number of miles he drive over 10 miles

Dependent variable = Total fee (in dollars)
