You can simply put the equation as 9x = 36 and divide by 9, then x = 4

Answer:

Step-by-step explanation:

the x-intercept is where y = 0 so you input 0 for y. It then becomes 9x = 36 so to find x its 39 divided by 9 which is 4 so the x intercept is 4

Answer: 0) 0.22

1) 0.20

2) 0.12

3) 0.14

4) 0.28

5) 0.04

<u>Step-by-step explanation:</u>

The total frequency is 33+30+18+21+42+6 = 150. This means they ran the experiment 150 times. The probability (P) is calculated by the satisfactory number of outcomes (frequency) divided by the total number of experiments/outcomes (total frequency):

$\begin{array}{c|c||lc}\underline{x}&\underline{f}&\underline{f\div 150}&\underline{\text{P}}\\0&33&33\div 150=&0.22\\1&30&30\div150=&0.20\\2&18&18\div 150=&0.12\\3&21&21\div 150=&0.14\\4&42&42\div 150=&0.28\\5&6&6\div 150=&0.04\end{array}\right]$
