1/5 written as a decimal just divide 1 by 5 and you get: 0.2 as a decimal.

(a^3+a^2b/5a)(25/3b+3a)

zheka24 [161]

Answer:

$\frac{5a}{3}$

Step-by-step explanation:

The given expression is;

$(\frac{a^3+a^2b}{5a})(\frac{25}{3b+3a} )$

Factorize;

$(\frac{a^2(a+b)}{5a})(\frac{25}{3(b+a)} )$

Cancel out the common factors;

$(\frac{a(1)}{1})(\frac{5}{3(1)} )$

Simplify;

$\frac{5a}{3}$

Graph the system of linear inequalities, please explain the process in solving this problem so I know how to do ones similar to

Ierofanga [76]

Graph the system of linear inequalities

x + y > 5

- x - y < -5

First we graph x + y >5

Step 1: replace > symbol by = sign

x + y =5

step 2 : Solve the equation for y

x + y =5 (subtract x from both sides)

y = 5 - x

step 3: Now we make a table . plug in some number for x and find out y

x -----> y

-1 -----> 6 ( y=5-x => y=5-(-1)= 6)

0 -----> 5 ( y=5-x => y=5-(0)= 5)

1 -----> 4 ( y=5-x => y=5-(1)= 4)

Step 4: we graph the table.

step 5: Shade the region that satisfies our inequality

x + y > 5. Greater than symbol implies that we shade the graph to the right

Graphing second inequality - x - y < -5

All terms have negative sign . so divide all the terms by -1. When we divide an inequality by -1 its sign changes

- x - y < -5 becomes x + y > 5

Follow the same steps to graph this inequality

After dividing the second equation by -1 , we got the same as the first equation.

So we will get the same graph

Both graphs overlaps

The graph of first and second inequality overlaps

A coin has heads on one side and tails on the other. The coin is tossed 12 times and lands

Fynjy0 [20]

Answer:

D, the observed frequency of landing heads up gets closer to the expected frequency based on the probability of the coin landing heads up.

Step-by-step explanation:

As of now, the observed frequency states that the coin will land on heads 4/12 times. The expected frequency states that the coin will land on heads 50% of the time, or 6/12 times. As the number of trials increases, the observed frequency will get closer to the expected frequency.

Answer:

It is the 3rd option. If it doesn't have a line below it, the circle should be open. And where the arrow points is where your line should go if that makes sense.
