ale4655 [162]

Answer:

$\$36.25+\$3.89x\le \$58.50$

Step-by-step explanation:

Let x be the number of folders with paper Jessica buys. If Jessica buys x folders for $3.89 each, then she pays $3.89x for all x folders.

She wants to buy one backpack for $36.25, so her total buying costs

$36.25 + $3.89x

Jessica saved a total of $58.50 to spend on school supplies, then her total buying cannot exceed this sum, so

$\$36.25+\$3.89x\le \$58.50$

Easy, so absolute value makes anything inside into positive
|x|=2
therefor x=-2 or x=2 since it would be made posotive

ATHLETICS of 107 athletes surveyed about what sport they play, some play basketball. of those that play basketball , 48 play bas

aliina [53]

the number of athletes who do not play basketball is 26.

Step-by-step explanation:

DATA:

Athletes surveyed = 107 athletes

Athletes who play basketball

Athletes who play baseball = 48 athletes

Athletes who don't play baseball = 33 athletes

Athletes who play basketball = athletes who play baseball + athletes who don't play baseball

Athletes who play basketball = 48 + 33

Athletes who play basketball = 81

EQUATION:

Total athletes = Athletes who play basketball + Athletes who don't play basketball

107 = 81 + x

x = 107 - 81

x = 26

Therefore, the number of athletes who do not play basketball is 26.

At a Noodles & Company restaurant, the probability that a customer will order a nonalcoholic beverage is .42. Find the proba

pashok25 [27]

Answer:

0.497

Step-by-step explanation:

Using the binomial probability formula :

P(x =x) = nCx * p^x * (1 - p)^(n - x)

From the question :

n = 6 ; x = 3 ; p = 0.42

P(x = 3) +... P(x = 6)

P(x = 3) = 6C3 * 0.42^3 * (1 - 0.42)^(6-3)

P(x = 3) = 20 * 0.074088 * 0.195112

P(x = 3) = 0.28910915712

Then find p(x = 4).. + p(x = 6)

Using a calculator :

P(X >= x) = 0.497

Hi there!

»»————-　★　————-««

I believe your answer is:

$x = \frac{1}{4}$

»»————-　★　————-««

Here’s why:

⸻⸻⸻⸻

$\boxed{\text{Solving the equation for x...}}\\\\4x + 54 = 55\\----------\\\rightarrow 4x + 54 - 54 = 55 - 54\\\\\rightarrow 4x = 1\\\\\rightarrow \frac{4x=1}{4}\\\\\rightarrow \boxed{x=\frac{1}{4}}$

⸻⸻⸻⸻

»»————-　★　————-««

Hope this helps you. I apologize if it’s incorrect.
