There is a bag with only red marbles and blue marbles. The probability of randomly choosing a blue marble is
3/8
There are 56 marbles in total in the bag and each is equally likely to be chosen.
Work out how many red marbles there must be.

red marbles

Step-by-step explanation:

Since the formula is;

Probability = number of required outcome

number of possible outcome

3/8. = x/56

8x. = 168

x. 21 ( number of blue marbles)

Therefore if the total marbles = 56 and 21 of the marbles are blue then to get the red marbles

= 56 - 21

= 35

f(x) is going down by 4

step-by-step explanation:

(its either that or its going left by 4)

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth
