Which number has a cube root between 7 and 8
lubasha [3.4K]

<u>Step-by-step explanation:</u>

<u>Here </u> ,There are no options given to choose which number is a cube root between 7 & 8 . So below provided answer is way to choose which numbers have cube root between 7 & 8 .

Here  , We have to find that Which number has a cube root between 7 and 8  . Let's find out :

We know that ,

\sqrt[3]{343}  = 7\\\sqrt[3]{512}  = 8

So , the number which have cube root between 7 & 8 will surely lie in between of 343 & 512  . Suppose the numbers which which have cube root between 7 & 8  are x_1,x_2,x_3,....,x_n , So these numbers lie between 7 & 8 i.e.

⇒ 343

Therefore, all the numbers which lies between 343 and 512 or 343  , have a cube root between 7 & 8 .

When a truckload of apples arrives at a packing plant, a random sample of 150 is selected and examined for bruises, discoloratio
myrzilka [38]

Answer:

c. 0.088

Step-by-step explanation:

Let p(s) be the proportion of apples defected in the sample. The probability that p(s)<0.05 can be calculated by calculating z statistic of 0.05:

\frac{p(s)-p}{\sqrt{\frac{p*(1-p)}{N} } } where

  • p(s) = 0.05
  • p is the proportion of the apples in fact defected (0.08)
  • N is the sample size (150)   Then,

z(0.05)=\frac{0.05-0.08}{\sqrt{\frac{0.08*0.92)}{150} } }=-1.354

And P(z<-1.354)≈0.0879

Therefore the probability that  a random sample of 150 among 8% defected apples can be accepted is 0.088.
