Answer:
≈ 70.4 cm
Step-by-step explanation:
The circumference (C) of a circle is calculated as
C = 2πr ( r is the radius ) , thus
C = 2 × 3.142 × 11.2 ≈ 70.4 ( to 1 dec. place )
Answer: The required probability is 0.615.
Step-by-step explanation:
Let A be the event that a product receives good reviews.
Let E₁ be the event that the product is highly successful.
Let E₂ be the event that the product is moderately successful.
Let E₃ be the event that the product is poor.
(a) What is the probability that a product attains a good review.
So, it becomes,
Hence, the required probability is 0.615.
Answer: a = -5
Heyy, so with this question you would have to substiute 1 for x because normally the coordinates have x first then y. E.g. (x,y)
soo, f(1) = a(1)^2 +5
then, f(1) = a + 5
then equate to zero. E.g. a+5=0
then move over 5 to other side E.g. a=-5
soo.. yah.. pretty sure haha :)
The first and last term factor into (2x+7) since this is a perfect square trinomial the answer must be 28
Answer:
820
Step-by-step explanation:
If you use order of operations, you can find that 3x0 and 1x400x100x456x0 is just 0 so you just have to add 2x2 and 34x24. Which is 820
order of operations is
GEMDAS
Grouping symbols
exponents
multiplication and division (these don't have to be in order)
Addition and Subtraction (again, these don't have to be in order)
