Step-by-step explanation:

area of circular pizza=pie*diameter

=1/4*pie*d^2

=3.14/4*100

=314/4

=78.5

area of square pizza=l^2

=9^2

=81

therefore square pizza is bigger in area than circular pizza.

jek_recluse [69]

Answer:

A) 38.62 ft

B) 92.27 ft

C) 32.59 ft

Step-by-step explanation:

A) tan10= x/185

X= 32.62 + 6ft= 38.62ft

B) tan25= x/185

X= 86.27 + 6ft= 92.27ft

C) 92.27 - 6ft= 86.27

86.27+ 32=118.27

use inverse of tan tan-1= 118.27/185 in which you get 32.59ft

Suppose that a die-hardly-ever battery has an exponential time-to-failure distribution with a mean of 48 months. at 60 months, t

mel-nik [20]

Since the time to failure distribution is exponential, the distribution is F (n) = 1 – e ^ (-x/48)

The probability of failure between months 60 and 72 is the same as the probability that the battery will fail in 12 months, since the exponential distribution is memoryless F (12) = 0.221

The process that produces Sonora Bars (a type of candy) is intended to produce bars with a mean weight of 56 gram. The process s

QveST [7]

Answer: z= -1.636

Step-by-step explanation:

When population standard deviation is known, then the test statistic is given by :-

$z=\dfrac{\overline{x}-\mu}{\dfrac{\sigma}{\sqrt{n}}}$

, where $\overline{x}$ = sample mean, $\mu$ = population mean, n=sample size , $\sigma$ = standard deviation

As per given,

$z=\dfrac{55.82-56}{\dfrac{0.77}{\sqrt{49}}}\\\\ z=\dfrac{-0.18}{\dfrac{0.77}{7}}\\\\z=\dfrac{-0.18}{0.11}\\\\z=-1.636$

Hence, the e test statistic to see whether the candy bars are smaller than they are supposed to be : z= -1.636
