What is r in this equation? 3 3/4 + r = 5 3/8

gayaneshka [121]

Answer:

r is 1 5/8

Step-by-step explanation:

3 3/4 is the same as 3 6/8, now both denominators are the same.

5 3/8 - 3 6/8 is the same as 43/8-30/8 which is 13/8, or in mixed number form, 1 5/8.

So r=1 5/8

SERIOUS ANSWERS ONLY PLZ

Answer:

The standard deviation of the uniform distribution is:

σ=(b−a)/√12

U(3, 12)

σ = (12−3)/√12 = 9/√12 = 2.5981

U(80, 250)

σ = (250−80)/√12 = 170/√12 = 49.0748

U(4, 93)

σ = (93−4)/√12 = 89/√12 = 25.6921

Calculus: Help ASAP

Serggg [28]

$\bf \displaystyle \int\limits_{-1}^{0}~(4x^6+2x)^3(12x^5+1)\cdot dx\\\\
-------------------------------\\\\
u=4x^6+2x\implies \cfrac{du}{dx}=24x^5+2\implies \cfrac{du}{2(12x^5+1)}=dx\\\\
-------------------------------\\\\
\displaystyle \int\limits_{-1}^{0}~u^3\underline{(12x^5+1)}\cdot\cfrac{du}{2\underline{(12x^5+1)}}\implies \cfrac{1}{2}\int\limits_{-1}^{0}~u^3\cdot du\\\\
-------------------------------\\\\$

$\bf \textit{now, we'll change the bounds, using u(x)}
\\\\\\
u(-1)=4(-1)^6+2(-1)\implies u(-1)=2
\\\\\\
u(0)=4(0)^6+2()\implies u(0)=0\\\\
-------------------------------\\\\
\displaystyle \cfrac{1}{2}\int\limits_{2}^{0}~u^3\cdot du\implies \left. \cfrac{1}{2}\cdot \cfrac{u^4}{4} \right]_{2}^{0}\implies \left. \cfrac{u^4}{8} \right]_{2}^{0}\implies [0]-[2]\implies -2$
