Answer:
Step-by-step explanation:
1. To solve this problem the first thing you can do is divide both sides of the quadractic equation by -4, then:
2. Now, to factor the quadratic equation you must find two numbers whose sum is -3/4 and the product is 1/4. These numbers are -1/4 and 1. Therefore, you have:
3. And the roots are:
If 25% of the jelly beans are red, the probability of red = 25/100 = 1/4
Then the probability of not red = 1 - 1/4 = 3/4
Ans: P(Not red) = 3/4
Answer:
Step-by-step explanation:
m∠OPQ = 23°
Well the formula for Volume of a Rectangular Prism is {Length x Width x Height = Volume}
So we know 18.5 x 9 x Length = 2,830.5
Divide by 18.5 and 9 and you are left with the length of 17 xD
