Linda pulls out a tie from a box containing blue, black, and red ties. she records the color and places it back into the box. the table below shows the frequency of each color after 100 ties are pulled out.

number of draws
25 20 55

how many red draws can you expect if the ties are pulled out 1,000 times?

The number of red draws expected are 550.

Step-by-step explanation:

We are given that,

Linda pulls out a tie from the box containing blue, black and red ties.

The frequency table for the different color ties after 100 ties are pulled out is,

Color             Number of Draws

Blue                        25

Black                      20

Red                         55

So, we get,

The probability of red colored tie being pulled out of 100 =

Thus, the number of red ties drawn out after 1000 ties pulled out = = 550

Hence, the number of red draws expected are 550.

x = 2

step-by-step explanation:

if sr parallel to ba then the sides bc and ac are in proportion, that is

= ← substitute values

= ( cross- multiply )

27x = 6(4x + 1)

27x = 24x + 6 ( subtract 24x from both sides )

3x = 6 ( divide both sides by 3 )

x = 2

the answer is  

a.
