Answer:

Option D.

Step-by-step explanation:

Northlake high school has two lunch periods. Students can eat their lunch in the cafeteria or on an outside patio.

Percentage of students who have first lunch eat outside= \frac{\text{Eat outside}}{\text{Total of first lunch}} = \frac{(.17)(100)}{.55}=31%

Similarly percentage of second lunch students eat outside= \frac{\text{Eat outside}}{\text{Total of second lunch}} = \frac{(0.21)(100)}{(0.45)}=47%

Therefore, option D is the correct option.

A rectangle that had the perimeter of 70 and the area of 250 has enlarged; its sides became twice as long. what is the new area
aliya0001 [1]
The perimeter of the original rectangle is:
 P = 2w + 2l = 70
 The area of the original rectangle is:
 A = w * l = 250
 Then, by modifying the length of its sides we have:
 Perimeter:
 P '= 2 (2w) +2 (2l)
 Rewriting:
 P '= 2 (2w + 2l)
 P '= 2P
 P '= 2 (70)
 P '= 140
 Area:
 A '= (2w) * (2l)
 Rewriting:
 A '= (2) * (2) (w) * (l)
 A '= 4 * w * l
 A '= 4 * A
 A '= 4 * 250
 A '= 1000
 Answer:
 
the new area and the new perimeter are:
 
P '= 140
 
A '= 1000

The packaging lists a model airplane’s length as 10.5 in. It also gives the scale as 1:83. What is the length of the actual airp
Lana71 [14]
\bf \cfrac{\stackrel{model}{length}}{\stackrel{actual}{length}}\qquad 1:83\qquad \cfrac{1}{83}\implies \cfrac{1}{83}=\cfrac{10.5}{x}\implies x=\cfrac{83\cdot 10.5}{1}
\\\\\\
x=871.5~inches
\\\\\\
\textit{there are 12 inches in 1 foot, thus }
\\\\\\
871.5~\underline{in}\cdot \cfrac{ft}{12~\underline{in}}\implies 72.625~ft 
\qquad \approx 73~ft

Tony’s class needs more than $500 for the school dance. So far, they have raised $200. They plan to have a car wash, charging $8
anzhelika [568]
<h2><em><u>PLZ MARK BRAINLIEST</u></em></h2><h2><em><u></u></em></h2>

No, he is not correct for if they washed 37 cars they would have made a total of 296 dollars washing cars. Because this is an inequality, he needs to get a value equal too or greater than 300 dollars on car washes. Also, because he already has 200 dollars collected, you could write the inequality as "8x is greater than or equal to 300".

It is known that 70% of the customers in a sporting goods store purchase a pair of running shoes. a random sample of 25 customer
NikAS [45]

Let x be the discrete random variable whose value is the number of successes in n trials.

The probability distribution function for x of the binomial distribution B(n,p) is defined as

B(n,p)= nC_xp^x(1-p)^{n-x}

Given that the random sample size is n=25

let x represent number of customers who purchase running shoes

Let "p" be the probability of customers in a sporting goods store purchase a pair of running shoes.

It is given that 70% of the customers in a sporting goods store purchase a pair of running shoes.

Thus p=\frac{70}{100}=0.7

Thus the Probability distribution of x is given by

P(X=x)= 25C_x(0.7)^x(1-0.7)^{25-x}, where x=0,1,2,3,...,25.
