First rewrite 8/25 and 7/20 so that they have a common denominator

Pie

Answer:

8/25 = 32/100
7/20 = 35/100

Step-by-step explanation:

25 and 20 have a least common multiple of 100, so that is your least common denominator.

8/25 = (8·4)/(25·4) = 32/100

7/20 = (7·5)/(20·5) = 35/100

What is the probability of tossing a penny and landing on heads 3 times in a row

Rasek [7]

Answer:

Suppose you have a fair coin: this means it has a 50% chance of landing heads up and a 50% chance of landing tails up. Suppose you flip it three times and these flips are independent. What is the probability that it lands heads up, then tails up, then heads up? So the answer is 1/8, or 12.5%.

Here's a graph of a linear function. Write the equation that describes that function. (Express it in slope-intercept form.)

rusak2 [61]

Answer:

$y=\frac{1}{2}x+4$

Step-by-step explanation:

The equation of a linear function in a slope-intercept form is written as

$y=mx+q$

where

m is the slope of the line

q is the y-intercept

We proceed as follows. First of all, we find the y-intercept, which is the value of y at which the line touches the y-axis.

From the graph, we see that this occurs at y = 4, therefore the y-intercept is

$q=4$

Now we have to find the slope. We do that by choosing two points along the line, with coordinates $(x_1,y_1)$ and $(x_2,y_2)$ and by using the equation
