sergejj [24]

Answer:

0.0062 = 0.62% of the 24-ounce bags contain less than the advertised 24 ounces of chips.

Step-by-step explanation:

Normal Probability Distribution:

Problems of normal distributions can be solved using the z-score formula.

In a set with mean \mu and standard deviation \sigma, the z-score of a measure X is given by:

Z = \frac{X - \mu}{\sigma}

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.

Mean of 24.5 ounces and a standard deviation of 0.2 ounce.

This means that \mu = 24.5, \sigma = 0.2

What proportion of the 24-ounce bags contain less than the advertised 24 ounces of chips?

This is the p-value of Z when X = 24. So

Z = \frac{X - \mu}{\sigma}

Z = \frac{24 - 24.5}{0.2}

Z = -2.5

Z = -2.5 has a p-value of 0.0062.

0.0062 = 0.62% of the 24-ounce bags contain less than the advertised 24 ounces of chips.

What is the surface area of this prism?
kap26 [50]

Answer:

736 cm2

Step-by-step explanation:

A= bxh/2

A=12x8/2

A=96/2

A=48x2=96 cm2

A=LxW

A=20x12

A=240 cm2

A=LxW

A=20x10

A=200x2=400 cm2

SA=96+240+400

SA=736 cm2

Let a be the vector of length 125 that when drawn in standard position makes a 144° angle with the positive x-axis. Let b be the
umka2103 [35]

Answer:

The length is 90.033 and the angle that v makes with the positive x-axis is 153.339°

Step-by-step explanation:

Firstly we will have to convert our given vectors to their rectangular Cartesian vector form as follow,

a=125(icos(144)+jsin(144))=-101.127i+73.473j\\b=39(icos(302)+jsin(302))=20.667i-33.074j

Now that we have these, we can add them to obtain v as follows,

v=a+b\\v=-80.46i+40.399j

Now that we have the Cartesian vector form we can calculate its length and its direction with respect to the positive x-axis as follows(In fact we usually refer the angles from the positive x-axis),

|v|=\sqrt{80.46^{2}+40.399^{2}}=90.033\\ angle(v)=tan^{-1}(40.399/(-80.46))=153.339

So the length of the vector is 90.033 and the angle it makes with the positive x-axis is 153.339°.
