Answer: So the number of outcomes with exactly 4 tails is 720/2/24 = 15. Finally we can now calculate the probability of getting exactly 4 tails in 6 coin tosses as 15/64 = 0.234 to 3 decimal places.
Answer:
1.79553
Step-by-step explanation:
Step 1: Write expression
log₁₀(√(69.5² - 30.5²))
Step 2: Evaluate square root
log(√(4830.25 - 930.25))
log(√3900)
log(62.45)
Step 3: Find log
log₁₀ (or log)
log(62.45) = 1.79553
-------------------------------------
To use the table method. we find values that are easily evaluated by log₁₀
log₁₀(10) = 1
log₁₀(50) = 1.69897
log₁₀(100) = 2
So we know that log₁₀(62.45) is between 1 and 2 and greater that 1.69897.
It would be C and here's why:
you originally start with 3x² - 14x - 5. The AC method to factoring says you have to get two middle terms that multiply to whatever 3 × -5 is and have to add to -14. Well 3 × -5 is -15. Raul chose two middle terms of 15x and -1x and 15 × -1 is -15 so that part is correct. However 15 - 1 = 14. The middle term of our original trinomial is -14 so "<span>The two middle coefficients multiply to the correct number, but do not add to the correct number."</span>
A single value randomly selected from the distribution of W will vary 4 by 3.5 attempted experiments. (collegboard)
Answer:
B. Dilations of an angle are congruent to the original angle.
E. Dilations of a triangle can be similare to the original triangle.
Step-by-step explanation:
These both look like the only correct ones.
