Answer:

Greater probability of gray than black = 3/25

Step-by-step explanation:

Given:

Total block = 5 x 5 = 25

Number of black blocks = 6

Number of gray blocks = 9

Find:

Greater probability of gray than black

Computation:

Greater probability of gray than black = Probability of gray - Probability of black

Greater probability of gray than black = 9/25 - 6/25

Greater probability of gray than black = 3/25

What is the value of the expression 1/2 (m-2/3n) when m=3/2 and n= 1/2 ?
yawa3891 [41]

Answer:

B.\frac{7}{12}

Step-by-step explanation:

m=\frac{3}{2}\\n=\frac{1}{2\\} \\\frac{1}{2} (m-\frac{2}{3} n)=\frac{1}{2} (\frac{3}{2} -\frac{2}{3} .\frac{1}{2} )\\=\frac{7}{12}

So B is the correct answer.

Find the length of the curve. R(t) = 7t, 3 cos(t), 3 sin(t) , −2 ≤ t ≤ 2
Leviafan [203]

we are given

r(t)=(7t,3cos(t),3sin(t))

we can find x , y and z

x=7t,y=3cos(t),z=3sin(t))

now, we can use arc length formula

L=\int\limits^a_b {\sqrt{(x')^2+(y')^2+(z')^2} } \, dt

now, we can find derivative

x'=7,y'=-3sin(t),z'=3cos(t))

now, we can plug values

and we get

L=\int _{-2}^2\sqrt{7^2+\left(-3\sin \left(t\right)\right)^2+\left(3\cos \left(t\right)\right)^2}dt

L=\int _{-2}^2\sqrt{7^2+9}dt

=\sqrt{58}\cdot \:2-\left(-2\sqrt{58}\right)

L=4\sqrt{58}...........Answer
