Answer:

$6\frac{3}{4}\ ft$

Step-by-step explanation:

we know that

To find out how long is Ms.Smith’s bulletin board, multiply Mrs . Porcelli’s bulletin board by 3

so

$2\frac{1}{4}(3)$

but first convert mixed number to an improper fraction

so

$2\frac{1}{4}\ ft=2+\frac{1}{4}=\frac{9}{4}\ ft$

substitute

$\frac{9}{4}(3)=\frac{27}{4}\ ft$

convert to mixed number

$\frac{27}{4}\ ft=\frac{24}{4}+\frac{3}{4}=6\frac{3}{4}\ ft$

Several trays of danishes are ordered for a breakfast about 35% or cream filled there are four trays of 18 danishes on each tray

zvonat [6]

There are 25 danishes contain cream filling

<h3>Further explanation</h3>

The percent is a number that shows a comparison of the number 100 or can be called per hundred (symbol%)

Formula used:

$\large{\boxed{\bold{Percentage\:=\:\frac{Total\:Section}{Total\:Amount}\:\times\:100\percent}}}$

Fractions either proper or mixed (consisting of numerators and denominators) or decimal forms

The percentage can be expressed as a decimal by moving the decimal point two places to the left

One way to convert proper fractions to percent forms is by multiplying the fraction by 100% or By changing the denominator to 100 because percent is the percent. Multiply the numerator and denominator with the same number

35% from Several trays of danishes are filled with cream

There are four (4) trays

18 danishes on each tray

Total danishes :

$\displaystyle =18\times 4\\\\=72\:danishes$

35% are filled with cream

$\displaystyle = \frac{35}{100}\times 72\\\\=\boxed{\bold{25.2}}$

Round up to 25 danishes

A marketing firm would like to test-market the name of a new energy drink targeted at 18- to 29-year-olds via social media. A st

Anon25 [30]

Answer:

(a) The probability that a randomly selected U.S. adult uses social media is 0.35.

(b) The probability that a randomly selected U.S. adult is aged 18–29 is 0.22.

(c) The probability that a randomly selected U.S. adult is 18–29 and a user of social media is 0.198.

Step-by-step explanation:

Denote the events as follows:

X = an US adult who does not uses social media.

Y = an US adult between the ages 18 and 29.

Z = an US adult between the ages 30 and above.

The information provided is:

P (X) = 0.35

P (Z) = 0.78

P (Y ∪ X') = 0.672

(a)

Compute the probability that a randomly selected U.S. adult uses social media as follows:

P (US adult uses social media (X')) = 1 - P (US adult so not use social media)

$=1-P(X)\\=1-0.35\\=0.65$

Thus, the probability that a randomly selected U.S. adult uses social media is 0.35.

(b)

Compute the probability that a randomly selected U.S. adult is aged 18–29 as follows:

P (Adults between 18 - 29 (Y)) = 1 - P (Adults 30 or above)

$=1-P(Z)\\=1-0.78\\=0.22$

Thus, the probability that a randomly selected U.S. adult is aged 18–29 is 0.22.

(c)

Compute the probability that a randomly selected U.S. adult is 18–29 and a user of social media as follows:

P (Y ∩ X') = P (Y) + P (X') - P (Y ∪ X')

$=0.22+0.65-0.672\\=0.198$

Thus, the probability that a randomly selected U.S. adult is 18–29 and a user of social media is 0.198.
