Answer: -2x + 5x^2
Step-by-step explanation:
3x + 6x^2 - 5x - x^2 = x(3-5) + x^2(6-1) = -2x + 5x^2
Answer:
The side length of the large square is √2 times larger than the side length of the small square.
Step-by-step explanation:
Suppose we have a small square (square 1) and a large square (square 2). The area of the large square is twice that of the small square, that is,
A₂ = 2 A₁
A₂/A₁ = 2 [1]
The area of a square is equal to the length of the side (l) raised to the second power.
A = l²
l = √A
The ratio of l₂ to l₁ is:
l₂/l₁ = √A₂ / √A₁ = √(A₂/A₁)
We can replace [1] in the previous expression.
l₂/l₁ = √2
The side length of the large square is √2 times larger than the side length of the small square.
Answer:
Proportion of buildings in the city that have fire code violations: 10%
Uncertainty 0.3 = 30%
Step-by-step explanation:
This situation complies with a binomial model where p is the probability of finding a building having fire code violations and q=1-p
Since in random sample of 40 buildings chosen for inspection 4 of them are found to have fire code violations, the proportion is 4/40 = 0.1 or 10% and p=0.1 as well.
<em>In a</em> <em>binomial model the standard deviation s is:
</em>
<em>
</em>
<em>where n is the sample size</em>. So
and the uncertainty is the standard error SE
Answer:
area=17cm^2
Step-by-step explanation:
Solve the individual boxes first.
2*1=2
3*5=15
2+15=17
