Answer:

24

Step-by-step explanation:

If you want to find the value of an unknown variable, you can reverse the equation

Instead of having 76+w=100, trying shifting the signs around to make 100-76=w

In this case, we can easily do 100-76= w in which w is equal to 24

90 men and 60 women were asked if they had watched the latest 'Expendables' movie.
Stolb23 [73]

Answer:

63 men said no.

Step-by-step explanation

3/5 * 2/2 = 6/10, 6/10 - 3/10 (women) = 3/10 meaning 7/10 men said no. 90*1.7 = 153, 153-90=63

6.4 Q3.) Use Simpson's rule to approximate and use the fundamental theorem of calculus to find the exact value of the definite i
Sav [38]

When we divide the interval from 1 to 5 into 4 subintervals, each has a width of 1. Simpson's rule has us evaluate the integral as

... integral = (1/3)(f(1) +4f(2) +2f(3) +4f(4) +f(5)) = (1/3)(10 +4·25 +2·46 +4·73 +106)

... integral = (1/3)(600) = 200 . . . . . by Simpson's rule

_____

The integral evaluates to

\displaystyle \int_{1}^{5}{\left(3x^2+6x+1\right)}\,dx=\left[x^3+3x^2+x\right]\limits_{1}^{5}=(5^3-1^3)+3(5^2-1^2)+(5-1)\\=124+3*24+4=200

_____

Simpson's rule uses a quadratic interpolation, so evaluates quadratics exactly.
