The number of potato chips in a bag is normally distributed with a mean of 75 and a standard deviation of 5. Approximately what
Oxana [17]

Approximately 95% of bags contain between 65 and 85 potato chips.

<u>Step-by-step explanation</u>:

step 1 :

Given,

The mean, M = 75

Standard deviation, SD = 5

step 2 :

From Normal distribution,

The left side of mean is 32% = M-SD, 16% = M-2SD and 2% = M-3SD

The right side of mean is 32% = M+SD, 16% = M+2SD and 2% = M+3SD

step 3 :

Calculate for left side: M-SD = 75-5 = 70 and M-2SD = 75-10 = 65

Calculate for right side: M+SD = 75+5 = 80 and M+2SD = 75+10 = 85

step 4 :

Calculate the percentage between 65 and 85:

(M-SD) + (M-2SD) + (M+SD) + (M+2SD) = 32% + 16% + 32% + 16%

                                                               = 96 % (which is approximately 95 %)

A sum of scalar multiples of two vectors (such as au + bv, where a and b are scalars) is called a linear conbination of the vect
belka [17]

Answer:

  -4u -5v

Step-by-step explanation:

Let the sum be ...

  <3, -27> = a<3, 3> +b<-3, 3>

This resolves to two equations

  3 = 3a -3b

  -27 = 3a +3b

Adding these together, we get

  -24 = 6a

  a = -4

Substituting into the second equation gives ...

  -27 = 3(-4) +3b

  -15 = 3b

  -5 = b

The desired linear combination is ...

  <3, -27> = -4<3, 3> -5<-3, 3> = -4u -5v

Emma's square patio below has been area=31 sq ft. She decides to decrease one dimension by 1 foot and decreases the other dimens
Andreas93 [3]

Answer:

4.57ft  by 1.57 ft

Step-by-step explanation:

We are given that

Emma's square patio has been area=31 sq.ft

One dimension decrease by 1 foot and other dimension decrease by 4 feet.

We have to find the new dimensions of Emma's patio.

Let x be the side of Emma's square patio

We know that

Area of square=x^2

x^2=31

x=\sqrt{31}=5.57 ft

One dimension=5.57-1=4.57 ft

other dimension=5.57-4=1.57 ft

Hence, the new dimension of Emma's patio is given by

4.57ft  by 1.57 ft
