The daily stock price for International Business Machines (IBM) historically has followed an approximately normal distribution (when adjusting for inflation) with a mean of $143.311 and standard deviation of $3.9988 Approximately 38.34% of days IBM had a stock price greater than what dollar amount

Answers

Answer 1

Answer:

Greater than $144.49.

Step-by-step explanation:

Normal Probability Distribution:

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

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

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

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 $143.311 and standard deviation of $3.9988.

This means that [tex]\mu = 143.311, \sigma = 3.9988[/tex].

Approximately 38.34% of days IBM had a stock price greater than what dollar amount?

Greater than X when Z has a p-value of 1 - 0.3834 = 0.6166, so X when Z = 0.295.

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]0.295 = \frac{X - 143.311}{3.9988}[/tex]

[tex]X - 143.311 = 0.295*3.9988[/tex]

[tex]X = 144.49[/tex]

Greater than $144.49.

i need the measurement of angle a

Answers

Given:-

Angle B = 90°

Angle C = 67°

To find:-

Angle A.

Solution:-

[tex]{\boxed{\mathcal{\red{Angle\: A \:=\: 23° \:}}}}[/tex]✅

Step-by-step explanation:-

We know that,

[tex]\sf\pink{Sum\:of\:angles\:of\:a\:triangle\:=\:180°}[/tex]

∠ A + ∠ B + ∠ C = 180°

➪ ∠ A + 90° + 67° = 180°

➪ ∠ A + 157° = 180°

➪ ∠ A = 180° - 157°

➪ ∠ A = 23°

[tex]\sf\red{Therefore, \:the\: value \:of \:∠\: A\: is \:23°.}[/tex]

To verify:-

A + B + C = 180°

23° + 90° + 67° = 180°

180° = 180°

L. H. S. = R. H. S.

Let r be the radius of the sphere. Then the volume of the sphere will be given as,

V = 4/3 πr³ cubic units

The radius of the sphere is 6 cm. Then the volume of the sphere is calculated as,

V = 4/3 x 3.14 x 6³

V = 904.32 cubic cm

The volume of the sphere will be 904.32 cubic cm.

Find the measure of each angle in the isosceles trapezoid.

Answers

Answer:

Below in bold.

Step-by-step explanation:

m < C = m < D = 64 degrees

m <A + m < D = 180

m < A + 64 = 180

m<A =  180 - 64 = 116 degrees.

m < B = m< A = 116 degrees.

Enter the number that belongs in the green box

Answers

Answer:

m<B = 107°

Step-by-step explanation:

∆ADC is congruent to ∆ABC by the SSS Congruence Theorem.

<D corresponds to <B, therefore,

m<D = m<B

m<D = 180° - (41° + 32°)

m<D = 180° - 73°

m<D = 107°

m<D = m<B = 107°

m<B = 107°

A regression was run to determine if there is a relationship between hours of tv watched per day (x) and the number of situps a person can do (y).The results of the regression were:y=ax+ba=−1.077b=30.98r2=0.744769r=−0.863Use this to predict the number of situps a person who watches 13.5 hours of TV can do.

Answers

Answer:

The number of situps is: 16.4405

Step-by-step explanation:

Given

[tex]y = ax + b[/tex]

[tex]a =-1.077[/tex]

[tex]b=30.98[/tex]

[tex]r^2 = 0.74476[/tex]

Required

Predict y when [tex]x = 13.5[/tex]

In the result, we have:

[tex]y = ax + b[/tex]

[tex]a =-1.077[/tex]

[tex]b=30.98[/tex]

This implies that:

[tex]y = -1.077x + 30.98[/tex]

To make prediction when [tex]x = 13.5[/tex]

We have:

[tex]y = -1.077*13.5 + 30.98[/tex]

[tex]y = -14.5395 + 30.98[/tex]

[tex]y = 16.4405[/tex]
