Gabriel can't decide whether to get a 16 oz can of Creamy Corn that sells for $1.09, or the 32 oz that's on sale for $1.89. Whic

Finger [1]

Answer:

I would say the 32 oz of corn, because even though they are the same unit price, you get more in the 32 oz of corn.

Step-by-step explanation:

Well, you can set up this equation to find out the unit price for the 16 oz of corn:

$1.09 divided by 16 = $0.06

Same with the 32 oz of corn:

$1.89 divided by 32 = $0.06

a. First five terms: 9,13,17,21,25

b. Sum of first 25 terms = 1425

c. The given sequence is an arithmetic sequence because the common difference between two consecutive terms is same.

Further explanation:

Given

Formula of sequence

$a_n=4n+5$

1. First 5 terms:

For first 5 terms, we have to put n=1,2,...5,

So,

$For\ n=1\\a_1=4(1)+5\\=4+5\\=9\\For\ n=2\\a_2=4(2)+5\\=8+5\\=13\\For n=3\\a_3=4(3)+5\\=12+5\\=17\\For\ n=4\\a_4= 4(4)+5\\=16+5\\=21\\For\ n=5\\a_5=4(5)+5\\=20+5\\=25\\First\ 5\ terms\ are: 9,13,17,21,25$

2. Sum of first 25 terms:

For that we have to find 25th term first

$a_{25} = 4(25)+5\\=100+5\\=105$

The formula for sum is:

$S_n=\frac{n}{2}(a_1+a_n)}\\Putting\ the\ values\\S_n=\frac{25}{2}(9+105)\\=12.5(114)\\=1425$

3. Type of sequence

The given sequence is an arithmetic sequence because the common difference between two consecutive terms is same.

i.e.

$d=4$

A sample of 255 observations is selected from a normal population with a population standard deviation of 27. The sample mean is

sladkih [1.3K]

Answer:

1.691

Step-by-step explanation:

Standard error of the mean is expressed as SEM = S/√n

S is the population standard deviation

n is the sample size (number of observation)

Given S = 27 and n = 255

SEM = 27/√255

SEM = 27/15.97

SEM = 1.691

Hence the standard error of the mean is 1.691

pochemuha

Step-by-step explanation:

$mean = \frac{(25.25 + 17.50 + 4.75 + 45.00 + 33.50 + 11.70 + 23.80 + 38.00 + 17.75 + 14.25)}{10} \\ = 23.15$
