5(871)=5*871 

\text{Set up the long multiplication.} 

\text{Calculate 5 x 1, which is 5.} 

\text{Calculate 5 x 7, which is 35.} 

\text{Since 35 is two-digit, we carry the first digit 3 to the next column.} 

\text{Bring down the carry digit of 3.} 

\text{Calculate 5 x 8, which is 40.} 

\text{Since 40 is two-digit, we carry the first digit 4 to the next column.} 

\text{Bring down the carry digit of 4.} 

\text{Calculate 5 + 350 + 4000, which is 4355} 

\text{Therefore, 5 x 871 = 4355.}

A cylinder has a surface area of 339 square centimeters and a radius of 6 centimeters. Estimate the volume of the cylinder to th
Andre45 [30]
SA=2hpir+2pir^2=2pir(h+r)
V=hpir^2

SA=339
r=6

339=2pir(h+r)
339=2pi3(h+3)
339=6pi(h+3)
divide both sides by 6pi
56.5/pi=h+3
minus 3 both sides
(56.5/pi)-3=h
(56.5-3pi)/pi=h
v=hpir^2
v=((56.5-3pi)/pi)(pi)(6)^2
v=(56.5-3pi)(36)
v=2034-108pi
use pi=3.141592

Ltd say we're given the quadratic equation x + 2x2 - 4 = -7x + 6
Zolol [24]

Answer:

x=1 ,x= -5

Step-by-step explanation:

x+2x2-4=-7x+6

2x2+x+7x-4-6=0

2x2+8x-10=0

divide through out by 2 to reduce the equation

x2+4x-5=0

by using formula method

x=[-b+\-√b2-4ac]/2a. a=1, b=4 c=-5

x=[-4+\-√4^2-4*1*-5]/2*1

x=[-4+\-√16+20]/2

x=[-4+\-√36]/2

x=[-4+\-6]/2

x=(-4+6)/2 ,x=(-4-6)/2

x=2/2 , x=-10/2

x=1 , x=-5

umka21 [38]

Answer:

Sample size shouldbe atleast 60

Step-by-step explanation:

Given that PTC is a substance that has a strong bitter taste for some people and is tasteless for others. The ability to taste PTC is inherited and depends on a single gene that codes for a taste receptor on the tongue. Interestingly, though the PTC molecule is not found in nature, the ability to taste it correlates strongly with the ability to taste other naturally occurring bitter substances, many of which are toxins.

Proportion of Italians who taste PTC =0.75

Margin of error <0.11

Confidence level = 95%

Std error of proportion = \sqrt{\frac{0.75*0.25}{n} }

Margin of error = 1.96*\sqrt{\frac{0.75*0.25}{n} }<0.11

\sqrt{n} >1.96*\sqrt{0.75*0.25} /0.11\\=17.81*0.4330\\=7.71\\n>59.47\\

Sample size shouldbe atleast 60
