Answer:
5) 27/70
6) 90
Step-by-step explanation:
5) The first step in this problem is to figure out the amount of total spins. To do so, add up all of the numbers in the column "Frequency".
18 + 15 + 27 + 10 = 70.
Now, look at the amount of times the spinner landed on green. This is 27 times. So, the ratio of green spins to total spins is 27:70, or 27 out of 70 spins. Converting this to a fraction, we get the final answer, 27/70.
6) To solve this problem, we have to first do the same steps as the previous problem, but with the color red. There are 70 total spins, and 18 red spins. Therefore, the ratio is 18:70. However, this problem wants the total number of spins to be 350. In other words, 70 needs to become 350. To do this, multiply each side of the ratio by 5. The ratio becomes 90:350. Using this ratio, we can determine that a solid prediction is 90 red spins out of 350 total spins.
41% and 0.41 im not sure for the last one but hope im right !!
3\div-2= \frac{-3}{2}3÷−2=2−3 direction of a line with the slope
The solution of the graphed system of equations y = -x² + x + 2 and y = -x + 3 is (1,2)
<h3>How to solve the equations?</h3>
The system of equations is given as:
y = -x² + x + 2
y = -x + 3
From the graph in the complete question, we have the following point of intersection between the equations
(x,y) = (1,2)
The point of intersection between the equations is the solution
Hence, the solution of the graphed system of equations is (1,2)

Answer:any number is correct
Step-by-step explanation:
4(3x+1)=12x+4
12x+4=12x+4
12x-12x=4-4
0=0
This equation has no answer.
Actually any number you put in place of x this equation will be true so we can say the answer is
X=infinity
