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

Need help with #9 please

zlopas [31]

The first, fourth and fifth ones are linear.

The second, third and sixth are all nonlinear.

You can tell this by the fact that their lead exponents are not 1.

PLEASE ANSWER THIS ASAP!!!!

Anit [1.1K]

Answer:

82 units

Step-by-step explanation:

7 x 3 = 21

21 x 2 = 42

7 x 2 = 14

14 x 2 = 28

2 x 3 = 6

6 x 2 = 12

42 + 28 + 12 = 82

PLEASE HELP 25 POINTS Write the equation for the following relation. Include all of your work in your final answer. Submit your

Deffense [45]

R = {(x, y): (4, 5), (8, 7), (12, 9), (16, 11), . . .}

Notice that y increases by 2 when x increases by 4

slope = 2/4 = 1/2

Notice that if you decrease x by 4 y will decrease by 2

So, y-intercept = (0,3)

Equation: y = (1/2)x+3

---------------------

R = {(x, y): (2, 3), (4, 4), (6, 5), (8, 6), . . .}

slope = 1/2

y-int: (0,1)

Equation: y = (1/2)x + 1

---------------------

Q = {(x, y): (2, 8), (3, 27), (4, 64), (5, 125), . . .}

Not a linear relation because y does not increase consistently

as x increases.

Equation: y = x^3

------------------------------

P = {(x, y): (1, 0), (2, 4), (3, 8), (4, 12), . . .}

slope = 4

y-int: -4

Equation: y = 4x-4

What’s a real number between the square root of 13 and the square root of 14

Pie

Real numbers can be both rational and irrational.

sqrt(13) = 3.60555

sqrt(14) = 3.74166

If you're looking for a rational number, there are lots of them to choose from. Easiest is probably 3.7 = 37/10.

An irrational number in this range might be sqrt(27/2).

Hope this helps!
