Find the median of the following set of data:
Troyanec [42]

Answer:

b

Step-by-step explanation:

The median is the middle value of the data set in ascending order. If there is no exact middle value then it is the average of the values either side of the middle.

Arrange the data in ascending order

48, 52, 54, 57, 57, 57, 61, 61, 65

                          ↑

The median of the data set is 57 → b

Find the area of the polygon.
zalisa [80]

Answer:

A=128\ cm^2

Step-by-step explanation:

we know that

The area of the polygon is equal to the area of a square plus the area of four congruent triangles

so

A=b^2+4[\frac{1}{2}(b)(h)]

where

b=8\ cm\\h=4\ cm

substitute

A=8^2+4[\frac{1}{2}(8)(4)]

A=64+64=128\ cm^2

Solve x4 – 17x2 + 16 = 0.<br> Let u =<br> Select all of the zeroes of the function. i i
Soloha48 [4]

Solve \ x^4 - 17x^2 + 16 = 0

To solve this equation , we need to write it in quadratic form

ax^2+bx+c=0

To get the equation in quadratic form we replace x^2 with u

x^2 = u

x^4 - 17x^2 + 16 = 0 can be written as

(x^2)^2 - 17x^2 + 16 = 0, Replace u for x^2

So equation becomes

u^2 - 17u + 16 = 0

Now we factor the left hand side

-16  and -1  are the two factors whose product is +16  and sum is -17

(u-16) (u-1) = 0

u -16 = 0  so u=16

u-1 =0  so u=1

WE assume u = x^2, Now we replace u with x^2

u = 16 so \ it \ becomes \ x^2 =16

Now take square root on both sides , x= +4  and x=-4

u = 1 so \ it \ becomes \ x^2 =1

Now take square root on both sides , x= +1  and x=-1

So zeros of the function are -4, -1, 1, 4

mestny [16]

Answer:

Question 1: She needs 12 blue beads and 48 black beads.

Question 2: She needs 10 blue beads and 25 black beads.

Step-by-step explanation:

I used ratios

question one's ratio is 3:12 and the second one's ratio is 4:10. If you keep that ratio consistent than those are the numbers you get based on the number of beads long she wants her necklace.

that's my best guess
