The answer is A. “The sum” indicates that we are adding. So if we’re finding the sum of -4x and 2 that means that we’re adding those two numbers. “Is” indicates that something is equal to or the same as, in this case it is equal to. The answer is; “-4x+2=9”

Monica took a survey of her classmates' hair and eye color. The results are in the table below.
jolli1 [7]

Answer:

let R represent red hair

let G represent green eyes

<em>from</em><em> </em><em>Baye's</em><em> </em><em>theorem</em><em>:</em>

<em>P( \frac{R}{G} ) =  \frac{P(RnG)}{P(G)}</em>

P(RnG) = 5

P(G) = { \sum}(green \: hair) \\  = (3 + 5 + 5) \\  = 13

Therefore:

P( \frac{R}{G} ) =  \frac{5}{13}  \\  = 0.385

The conditional relative frequency = 0.385

What is the perimeter of RSTUV?
MrMuchimi

Answer:

this should be 132 units   i hope this helps!   :)

Step-by-step explanation:

so these figures are similar

we are given 3 side measurements on one, and 3 on the other

we know that side BA is 10 units, and that SR which is the same side, is 14 units

we can conclude that they added 4 units to this side

so with the other side lengths that we are given we can figure out what the length of the perimeter of RSTUV is

10 + 4 = 14

15 + 4 = 19

28 - 4 = 24  

42 - 4 = 38

25 + 4 = 29

42 TU

28 UV

19 VR

14 SR

29 ST

add all the side together to get 132 units
