Answer:
No real solutions
Step-by-step explanation:
Using the quadratic formula, you will end up with a square root of a negative number in the numerator. Hence there is no real solution.

Hello, and thank you for posting your question here on brainly.
When you're dividing two fractions, there's a simple rule to follow.
You flip the second fraction, (aka reciprocal) and then multiply.
2/3 ÷ 1/4 = 2/3 * 4/1
You multiply across from the top and bottom.
2/3 * 4/1 = 8/3
8/3 = 2 2/3
Your final answer is C.
Hope this helps! ☺♥
What is the probablity for the number of times Jada will pull a tile wit a star?
Answer: Number of tiles pulled out of the bag by Jada = 10, so she completed 10 trials.
The outcome of each trial was star, circle or a square.
Step-by-step explanation: We can find the experimental probability of pulling each shape from the bag based on the outcomes of Jada's experiment and number of trial.
- P(Star) = Number of stars/Number of trials= 5/10
- P(Circles)= Number of circles/Number of trials =3/10
- P(Square) = Number of Square/Number of trials = 2/10
Here, P refers to Probability of an outcome
If Jada repeats the experiment, She would likely again pull more stars than circles or square. She may get different number of stars,circles or squares but over a large number of trials, she would expect the ratio of the stars in the proportion. We can use this proportonal relationship to get the reasonable prediction about te number of times she pull different shape tiles.
<u>Number of outcomes(10 trials) </u> = <u>Number of outcomes(100 trials)</u>
Number of trials(10 trials) Number of trials (100 trials)
- Numbeof stars = 5/10 =s/100
5*10/ 10*10 =50/100 - Number of Circle = 3/10 = c/100
3*10/10*10 = 30/100 - Number of square = 2/10 = q/100
2*10/10*10 = 20/100
If she does the experiment 100 times then she should expect to pull out 50 stars tile, 30 circles and 20 Square.
Hence, Jada pulled out the 100 tiles from the bag.

After 10 hours the temperature is shown on the graph as 30 degrees.
50 degrees - 30 degrees = 20 degrees.
The temperature dropped 20 degrees in 10 hours.
Divide the change by the time:
20 degrees / 10 hours = 2 degrees per hour.
Because the temperature dropped, the change would be negative.
The answer is D. -2 degrees per hour.
