Estimated answer is 4000 and actual answer is 3901
Step-by-step explanation:
- Step 1: Estimate 47 × 83 by rounding off to the nearest 10.
⇒ 47 ≈ 50 and 83 ≈ 80
⇒ 50 × 80 = 4000
- Step 2: Do the actual calculation of 47 × 83
47

Step-by-step explanation:
Answer:
A. 4
B. 1
Step-by-step explanation:
The degree of a one-variable polynomial is the largest exponent of the variable.
__
<h3>A.</h3>
For f(x) = x^4 -3x^2 +2 and g(x) = 2x^4 -6x^2 +2x -1, the sum f(x) +a·g(x) will be ...
(x^4 -3x^2 +2) +a(2x^4 -6x^2 +2x -1)
= (1 +2a)x^4 +(-3-6a)x^2 +2ax -a
The term with the largest exponent is (1 +2a)x^4, which has degree 4. This term will be non-zero for a ≠ -1/2.
The largest possible degree of f+ag is 4.
__
<h3>B.</h3>
The polynomial sum is ...
f+bg = (1 +2b)x^4 +(-3-6b)x^2 +2bx -b
When b = -1/2, the first two terms disappear and the sum becomes ...
f+bg = -x +1/2 . . . . . . a polynomial of degree 1
The smallest possible degree of f+bg is 1.
Answer:
There are approximately 88 adults.
Step-by-step explanation:
The question is:
A fair was attended by 350 people of which two thirds are adolescents and a quarter adults and a fifth are children from 10 to 12 what amount corresponds to adults
.
Solution:
Total number of people attending the fair is, <em>N</em> = 350.
The proportion of adults is: P (Adults) = <em>p</em> = 0.25.
Compute the number of adults in the fair as follows:
Thus, there are approximately 88 adults.
