A restaurant manager states the number of customers that enter the restaurant is equal to 4 times the number of people that buy

yarga [219]

Answer:

26 customers

Step-by-step explanation:

Represent customers entering as y and those buying hot dogs as x

$y = 4x + 9$

$y = 3x + 35$

Required

Determine the number of people buying hotdogs (x)

Substitute 4x + 9 for y in the second equation

$4x + 9 = 3x + 35$

Collect Like Terms

$4x - 3x = 35 - 9$

$x = 26$

Rewrite in rectangular form: r=5

SVETLANKA909090 [29]

Answer:

x ^2+ y^ 2 = 25

Step-by-step explanation:

Square both sides:

r ^2 = 5^ 2

Substitute x ^2 + y^ 2 for r ^2 :

x ^2+ y ^2 = 5 ^2

Insert the center -0 into the x and y terms:

( x − 0 )^ 2 + ( y − 0 ) ^2 = 5 ^2

This is the standard form for a circle whose center is ( 0, 0 ) and the radius is 5.

help solve this problem Based on a poll, 62% of Internet users are more careful about personal information when using a public

erma4kov [3.2K]

Answer

The probability that among four randomly selected Internet users, at least one is more careful about personal information when using a public Wi-Fi hotspot is 0.979.

Step-by-step explanation:

Since 62% of Internet users are more careful about personal information when using a public Wi-Fi hotspot.

Therefore, the Probability of 62% of Internet users are more careful about personal information when using a public Wi-Fi hotspot is, p=0.62.

We have to find the probability that at least one user is more careful about personal information when using wi-fi hotspot.

Probability of internet users are not more careful about personal information when using a public wi-fi hotspot, i.e $q=1-p$

$q=1-0.62=0.38$

Use Binomial Distribution, i.e, $P\left ( X \right )=^nC_xp^xq^\left ( n-x \right )$

p=0.62, q=0.38, n=4.

Required Probability $P\left ( X\geq 1 \right )=P\left ( X=1 \right )+P\left ( X=2 \right )+P\left ( X=3 \right )+P\left ( X=4 \right )$

$P\left ( X\geq 1 \right )=1-P\left ( X=0 \right )$

=1- $^4C_0p^0q^\left ( 4-0 \right )$

=1- $4\cdot1\cdot q^\left ( 4-0 \right )$

=1- $4\cdot \left ( 0.38 \right )^4$

=1-0.02085136=0.97914864

Therefore, the probability that at least one users more careful about personal information when using wi-fi hotspot, i.e 0.979(approx).

RESULT:

<u>The result should not be impacted by this because volunteers are likely to have the most relevant responds.</u>
