12-2(7x-3)=3(1-2x)-5x
vfiekz [6]
12 - 2(7x - 3) = 3(1-2x) - 5x
12 - 14x + 6 = 3 - 6x - 5x
-14x + 6x + 5x = 3 - 12 - 6
-3x = -15
x = -15/-3

Please help. will give brainliest ​
vichka [17]

Answer:

  • B. The probability that the student received a grade better than C is 0.45

Step-by-step explanation:

<u>Total number of students:</u>

  • 15 + 30 + 35 + 16 + 4 = 100
<h3>Statements</h3>

A.

  • p(<D) = 4/100 = 0.04
  • 0.04 ≠ 0.2
  • Incorrect

B.

  • p(>C) = (30 + 15)/100 = 45/100 = 0.45
  • 0.45 = 0.45
  • Correct

C.

  • p(not A or B) = (100 - 15 - 30)/100 = 55/100 = 0.55
  • 0.55 ≠ 0.45
  • Incorrect

D.

  • p(B or C) = (30 + 35)/100 = 65/100 = 0.65
  • 0.65 ≠ 0.35
  • Incorrect

Use Stokes' Theorem to evaluate S curl F · dS. F(x, y, z) = 5y cos(z) i + ex sin(z) j + xey k, S is the hemisphere x2 + y2 + z2
Alenkinab [10]

By Stokes' theorem, the integral of the curl of \vec F across S is equal to the integral of \vec F along the boundary of S, call it C. Parameterize C by

\vec r(t)=2\cos t\,\vec\imath+2\sin t\,\vec\jmath

with 0\le t\le2\pi. So we have

\displaystyle\iint_S(\nabla\times\vec F)\cdot\mathrm d\vec S=\int_C\vec F\cdot\mathrm d\vec r

=\displaystyle\int_0^{2\pi}(10\sin t\cos 0\,\vec\imath+e^{2\cos t}\sin0\,\vec\jmath+2\cos t\,e^{2\sin t}\,\vec k)\cdot(-2\sin t\,\vec\imath+2\cos t\,\vec\jmath)\,\mathrm dt

=\displaystyle\int_0^{2\pi}-20\sin^2t\,\mathrm dt

=\displaystyle-10\int_0^{2\pi}(1-\cos2t)\,\mathrm dt=\boxed{-20\pi}
