How to estimate 518 + 372

Answers

Answer 1
Answer:

Answer:

900

Step-by-step explanation:

518+372

We have to find the result by estimation

Estimate both the numbers to nearest  hundreds

518 is estimated to nearest hundred= 500

372 is estimated to nearest hundred= 400

After adding, 500 and 400, we get

500+400=900

we get our answer 900

Hence, the correct answer is 900
Answer 2
Answer: It is 890 but if you estimate it would be 900

What conic section does the equation x2 + y2 – 4y – 1 = 0 represent?ellipse

hyperbola

circle

parabola

Answers

The conic section that the above equation represents is a CIRCLE.

Use completing the square for y and put the equation in standard form: 
x²+ y² - 4y + [(-4)/2]² - 1 = 0 + [(-4)/2]²
x² + y² - 4y + (-2)² - 1 = 0 + (-2)²
x² + y² - 4y + 4 - 1 = 4 
x² + (y - 2)² - 1 = 4 
x² + (y - 2)² = 4 + 1
x² + (y -2)² = 5

The radius of the circle is the square root of 5. Its center is found at (0,2)

Liz flips a coin 70 times. The coin lands heads up 21 times and tails up 49 times. Complete each statement. The theoretical probability of the coin landing heads up is what%.

Answers

Final answer:

The theoretical probability of the coin landing heads up is 30%.

Explanation:

The theoretical probability of the coin landing heads up is 30%.

The number of times the coin lands heads up out of the total number of coin flips is called the experimental probability. In this case, the experimental probability is 21/70 = 0.3, or 30%.

The theoretical probability of getting heads on a fair coin is always 50%, but in this specific experiment, the experimental probability varied due to chance. As the number of coin flips increases, the experimental probability should approach the theoretical probability of 50%.
