Show work for 1.6 > 1.3

Brrunno [24]

1.6 is let's say one pie and 6/10 of a pie and that's how much a baker made which is obviously more that 1 pie and 3/10 of a pie that the baker made. A process for that is 1.6 =1 6/10 = 16/10 and if u cross multiply that by 1.3 = 1 3/10= 13/10 the value in the 16/10 side will be 160 which is more that the value on the 13/10 side which is 130

A researcher believes that 12% of a simple random sample of adults will be able to identify a Toyota Scion by brand and model na

DochEvi [55]

Answer: 650

Step-by-step explanation:

When prior estimate of population proportion is known , then the formula to find the required sample size is given by :-

$n=p(1-p)(\dfrac{z^*}{E})^2$

, where p= population proportion

E= margin of error

z* = Critical value.

Let p be the proportion of adults able to identify a Toyota Scion by brand and model name.

As per given , we have

p = 12%= 0.12

E= 2.5%=0.025

Critical value for 95% confidence interval : z* = 1.960 [By z-table ]

Then, the required sample size = $n=(0.12)(1-(0.12))(\dfrac{1.96}{0.025})^2$

$n=(0.1056)(78.4)^2$

$n=(0.1056)(6146.56)$

$n=649.076736\approx650$

Thus , the required sample size = 650

Answer:

60

Step-by-step explanation:

The exterior angles of the polygon are the supplement of the interior angles, so are ...

180° -174° = 6° . . . . measure of each exterior angle

The sum of exterior angles is 360°, so ...

n(6°) = 360°

n = 360°/6° = 60

The polygon has 60 sides.
