D. You can find a perpendicular line by finding the inverse equations (-(1/)2 x+3
Hello! I can help you with this!
1. Okay. 1/2 as a decimal is 0.5 and 8/9 is about 0.89. Just by looking at the answer choices, A and B are both eliminated, because they are less than 1/2. 22/24 is about 0.92 as a decimal, which is more than 0.889. C is eliminated, which leaves us with D. 19/24 is about 0.79, which is greater than 0.5, but less than 0.89. 19/24 is between 1/2 and 8/9. The answer is D: 19/24.
2. Okay. Finding the answe to this will require converting the improper fraction into decimals, through dividing. Just by looking at the answers, we can eliminate C and D, because those denominators are odd. That will not get us to 9.5 evenly. 9.5 is also 9 ½. Let's try A. 46/5 is 9.2. 9.2 < 9.5. A is out. 19/2 is 9.5. 9.5 = 9.5. There. 9.5 is 19/2 expressed as a fraction in simplest form. The answer is B: 19/2.
Answer:
3/8
Step-by-step explanation:
Three of the eight outcomes have exactly two heads: HHT, HTH, THH. The probability of getting exactly two heads is 3/8.
Direct variation is of the form y=kx, so y/x should be a constant, k...
-8/-2=-16/-4=-24/-6=k=4 so y=kx is:
y=4x
