The average weight of a particular box of crackers is 28.0 ounces with a standard deviation of 0.9 ounce. The weights of the box
Juliette [100K]

Answer:

a. 97.72%

Step-by-step explanation:

The weights of boxes follows normal distribution with mean=28 ounce and standard deviation=0.9 ounces.

a. We have to calculated the percentage of the boxes that weighs more than 26.2 ounces.

Let X be the weight of boxes. We have to find P(X>26.2).

The given mean and Standard deviations are μ=28 and σ=0.9.

P(X>26.2)= P((X-μ/σ )> (26.2-28)/0.9)

P(X>26.2)= P(z> (-1.8/0.9))

P(X>26.2)= P(z>-2)

P(X>26.2)= P(0<z<∞)+P(-2<z<0)

P(-2<z<0) is computed by looking 2.00 in table of areas under the unit normal curve.

P(X>26.2)=0.5+0.4772

P(X>26.2)= 0.9772

Thus, the percent of the boxes weigh more than 26.2 ounces is 97.72%

Given m||n, find the value of x , please help me I don't understand , I'm stressed lol
Klio2033 [76]

Answer:

x = 2

Step-by-step explanation:

because m || n, you can assume the two angles are congruent.

set them equal to each other:

5x - 4 = 4x - 2

<u>solve</u>

add 4 to both sides: 5x + (-4 + 4) = 4x + (-2 + 4) --> 5x = 4x + 2

subtract 4x from both sides: (5x - 4x) = (4x - 4x) + 2 --> x = 2
