Answer: The coefficient of determination = 0.6291

Step-by-step explanation:

Given: Total variation is 24.488, the explained variation is 15.405, and the unexplained variation is 9.083.

The coefficient of determination is computed as:

[tex]\text{ coefficient of determination} =\frac{\text{explained variation }}{\text{total variation}}[/tex]

Substituting given values, we get

[tex]\text{coefficient of determination} =\frac{15.405}{24.488}[/tex]

[tex]=0.6291[/tex]

Therefore, the coefficient of determination = 0.6291

The probability that when she opens a random picture from the computer folder, it will be a blurry picture she took with her cell phone is 7%.

Probability is the likelihood or tendency that something will occur.

Probablility of blurry picture=(134-86)×0.2/134

Probablility of blurry picture=48×0.2/134

Probablility of blurry picture=9.6/134×100

Probablility of blurry picture=7.16

Probablility of blurry picture=7% (Approximately)

Thus, the probability that when she opens a random picture from the computer folder, it will be a blurry picture she took with her cell phone is 7%.

The value of an exterior angle is equal to the sum of values of two opposite interior angles.

That is :

Therefore, value of x is 20°

And the measure of missing angle is :

The Value of an Exterior angle is equal to the sum of values of two opposite interior angles .

Hence,

And therefore measure of missing angle is 36°, since v was the missing angle here.

Answer:1/2

Step-by-step explanation:

Answer: x < 10

Step-by-step explanation: Just like any of your two-step equations, in this inequality, start by isolating the x term which in this case is 6x by adding 5 to both sides.

That leaves you with 6x < 60 and now just divide both sides by 2 and x < 10.

Notice that because we divide both sides of the inequality

by a positive number, not a negative, we did not change the

direction of the inequality sign.

Finally, put your answer in set notation, {x: x < 10}.

Unlike an equation which normally has one solution, the answer to an inequality must be stated as a solution set because an entire set of answers will work. In this problem, it's any number less than 10.

Answer:

The Smart family could paint 110 square feet per hour.

Step-by-step explanation:

Given that while remodeling their living room, the Smart family decided to repaint the walls, and they estimated that they could repaint 55 square feet every half-hour, to determine how many square feet can they paint per hour the following calculation must be performed:

1/2 = 0.5

0.5 = 55

1 = X

55 / 0.5 = X

110 = X

Therefore, the Smart family could paint 110 square feet per hour.

Answer:

300litres

Step-by-step explanation:

capacity of water tank=1000litres

7/10 parts of tank is emptied,

so, to know the litres of water left in the tank has to be equal to 1000litres-emptied tank

let X to represent water left in the tank

X=1000litres-(7/10*1000litres)

X=1000litres-700litres

X=300litres

hence, litres of water left in the tank =300litres

since, full tank is 10/10 and you know the emptied tank has 7/10. meaning the remaining part of water is

10/10-7/10

3/10 of the tank with water

therefore, 3/10*1000litres

300litres.

Answer:

705/100 grams cann be covered by the basic postage

Step-by-step explanation:

Given

Basic Postage

[tex]Weight < 7.5g[/tex]

Heavy letters

[tex]Weight \ge 7.5g[/tex]

Required

Can [tex]705/100[/tex] be covered in basic postage?

We have:

[tex]Weight = 705/100\ g[/tex]

[tex]Weight = 7.05\ g[/tex]

By comparing the above with the range of basic postage ---- [tex]Weight < 7.5g[/tex]

We have:

[tex]7.05g < 7.5g[/tex]

Since the above inequality is true, then the letter can be covered

Step-by-step explanation:

The test is formulated as hypothesis . Here the test ist that whether the treatment has  affected or not . So the null hypothesis can be formulated as

H0 : the treatment has no effect

against the claim

Ha: the treatment has an effect.

The null hypothesis  is the test performed and the alternate hypothesis is the claim against the test. Therefore they are opposite of each other.

Answer:

$75.5

Step-by-step explanation:

The first step is to calculate the percentage decrease

= 100-18

= 82%

Therefore the original cost of the shirt before the discount can be calculated as follows

= 82/100 × x = 61.91

= 82x/100= 61.91

Cross multiply

82x= 100×61.91

82x= 6191

x = 6191/82

= 75.5

Hencd the original cost of the shirt is $75.5

Answer:

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.
