Marissa is drawing coins from a bag that contains 5 pennies (yellow), 4 nickels (green), 5 dimes
Anna007 [38]

Answer:

\frac{4}{16}=\frac{1}{4}=0.25=25\%

Step-by-step explanation:

Total number of coins in the bag = 5 + 4 + 5 + 2 = 16 coins

Number of nickels in the bag = 4

We have to find the probability that Marissa draws a nickels from the bag.

Probability is defined as the ratio of Number of "Favorable Outcomes" to "Total number of possible outcomes"

In this case total number of possible outcomes is the total number of coins which is 16.

Favorable/Desires outcome is drawing a Nickle from the bag which are 4 in number. So, number of favorable outcomes is 4

Therefore, the probability that she will draw a nickel = \frac{4}{16}=\frac{1}{4}=0.25=25\%

2 1/2r + 1 + 2r = 9 1/10
GalinKa [24]

This should help you here are the steps of your problem :)


2*(1/2)*r+2*r+1 = 9*(1/10) // - 9*(1/10)


2*(1/2)*r+2*r-(9*(1/10))+1 = 0


2*(1/2)*r+2*r-9/10+1 = 0


3*r+1/10 = 0 // - 1/10


3*r = -1/10 // : 3


r = -1/10/3


r = -1/30


r = -1/30


So your answer would be 1/30

I need help on my math
shtirl [24]

Answer:

y = -5/4x - 4

Step-by-step explanation:

The equation they give you is in slope intercept form.  y=mx+b.  The m is the slope (-5/4).  Since they want a parallel line you keep the same slope for point slope form.  Point slope formula is y-y1=m(x-x1). the y1 and x1 are where you plug in the coordinates they give you.

y - 1 = -5/4x (x + 4)

y - 1 = -5/4x - 5

y = -5/4x - 4
