Arrange the number in increasing order<br><br><br> 14.204 14.200 14.240 14.210
Gnesinka [82]

Answer:

14.200,14.204,14.210,14.240

Step-by-step explanation:

To arrange in increasing order, we start from the least number and end on the highest number.

The given numbers are,14.204, 14.200, 14.240, 14.210

We can observe that:

14.200<14.204<14.210<14.240

Therefore the numbers in increasing order is 14.200,14.204,14.210,14.240

A store allows customers to fill their own bags of candy. Terri decides she only wants jelly beans and chocolate drops. Jelly be
NISA [10]
Jelly beans - $0.98 per pound
chocolate drops - $0.67 per pounds
Terri's bag = 2.1 pounds and $1.56

p = represents the pounds jelly beans.
c = represents the pounds in chocolate drops

p + c  = 2.1
0.98p + 0.67c = 1.56

c = 2.1 - p  ; number of pounds of chocolate drops

0.98p + 0.67(2.1 - p) = 1.56
0.98p + 1.41 - 0.67p = 1.56
0.98p - 0.67p = 1.56 - 1.41
0.31p = 0.15
p = 0.15/0.31
p = 0.48 pounds of jelly beans

c = 2.1 - 0.48
c = 1.62 pounds of chocolate drops.

According to a study done by the Pew Research Center, 39% of adult Americans believe that marriage is now obsolete. (a) Suppose
algol13

Answer:

The proportion follows normal distribution,

 Mean u = 0.39

 standard deviation σ = 0.0218

Step-by-step explanation:

Solution:-

- Lets assume the population proportion ( p ) to be the percentage of adult Americans who believe that marriage is now obsolete.

- We will check for normality:

 Lets take,   p^ = p  (Mean proportion of the distribution)

- The condition of normality,

                  n*p*( 1 - p ) ≥ 10

Where, n : The sample size taken.

                  500*0.39*( 1 - 0.39 ) = 500*0.39*( 0.61 )

                  118.95 ≥ 10

- Hence, with the testing statistics the condition for normality are validated. Hence, the distribution for proportion of adult americans who believe that marriage is now obsolete follows a normal distribution.

- The parameters of the distribution are:

    Mean : u = p^ = p = 0.39

    Standard deviation σ =  \sqrt{\frac{p*(1-p)}{n} } =    \sqrt{\frac{0.39*(1-0.39)}{500} }  = \sqrt{\frac{0.39*(0.61)}{500} } =0.0218
