Answer: 0.5625

Step-by-step explanation:

Using the binomial distribution, it is found that the probability that a player will toss the die at least 2 times before blue lands face up is:

D 0.5625

For each toss, there are only two possible outcomes, either blue lands face up, or it does not. The probability of blue landing face up on a toss is independent of any other toss, which means that the binomial distribution is used to solve this question.

Binomial probability distribution

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]

The parameters are:

In this problem:

The probability that a player will toss the die at least 2 times before blue lands face up is P(X = 0) when n = 2, hence:

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

[tex]P(X = 0) = C_{2,0}.(0.25)^{0}.(0.75)^{2} = 0.5625[/tex]

Hence, option D is correct.

Answer:

y = 7x + 4

Step-by-step explanation:

From the table given in the picture attached,

Let the linear equation representing the table is,  

y = mx + b

Here, m = Slope of the equation

b = Y-intercept

Since, slope of the line passing through [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] is given by,

m = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

Therefore, slope of the line passing through (20, 144) and (24, 172) will be,

m = [tex]\frac{172-144}{24-20}[/tex]

m = [tex]\frac{28}{4}[/tex]

m = 7

By substituting the value of m in the equation,

y = 7x + b

Since, this line passes through a point (20, 144),

By substituting the values of x = 20 and y = 144 in the equation,

144 = 7(20) + b

b = 144 - 140

b = 4

Therefore, equation of the line will be,

y = 7x + 4

Answer:

The approximate length of the missing side is of 5.57 cm.

Step-by-step explanation:

Pythagorean Theorem:

In a right triangle with sides a and b and hypotenuse c, the Pythagorean theorem states that:

[tex]a^2 + b^2 = c^2[/tex]

In this question:

[tex]a = 15, c = 16[/tex]

We want to find b. Then

[tex]a^2 + b^2 = c^2[/tex]

[tex]15^2 + b^2 = 16^2[/tex]

[tex]b^2 = 256 - 225[/tex]

[tex]b^2 = 31[/tex]

[tex]b = \sqrt{31}[/tex]

[tex]b = 5.57[/tex]

The approximate length of the missing side is of 5.57 cm.

Answer:

a) 0.9938 = 99.38% probability that the boxes will end up with at least 1 pound of cereal

b) 16.121 ounces.

c) 16.0664 ounces.

d) Between 16.0342 and 16.1658 ounces.

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 16.1 ounces, standard deviation of 0.04 ounces. So

[tex]\mu = 16.1, \sigma = 0.04[/tex]

(a) What is the probability of the boxes will end up with at least 1 pound of cereal?

One pound is 16 ounces, so this is 1 subtracted by the pvalue of Z when X = 16. So

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

[tex]Z = \frac{16 - 16.1}{0.04}[/tex]

[tex]Z = -2.5[/tex]

[tex]Z = -2.5[/tex] has a pvalue of 0.0062

1 - 0.0062 = 0.9938

0.9938 = 99.38% probability that the boxes will end up with at least 1 pound of cereal.

(b) The seventy percent of the boxes will contain less than what number of ounces?

Less than the 70th percentile, which is X when Z has a pvalue of 0.7. So X when Z = 0.525.

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

[tex]0.525 = \frac{X - 16.1}{0.04}[/tex]

[tex]X - 16.1 = 0.525*0.04[/tex]

[tex]X = 16.121[/tex]

16.121 ounces.

(c) Eighty percent of the boxes will contain more than what number of ounces?

More than the 100 - 80 = 20th percentile, which is X when Z has a pvalue of 0.2. So X when Z = -0.84.

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

[tex]-0.84 = \frac{X - 16.1}{0.04}[/tex]

[tex]X - 16.1 = -0.84*0.04[/tex]

[tex]X = 16.0664[/tex]

16.0664 ounces.

(d) The middle 90% of the boxes will be between what two weights?

Between the 50 - (90/2) = 5th percentile and the 50 + (90/2) = 95th percentile.

5th percentile:

X when Z has a pvalue of 0.05, so X when Z = -1.645.

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

[tex]-1.645 = \frac{X - 16.1}{0.04}[/tex]

[tex]X - 16.1 = -1.645*0.04[/tex]

[tex]X = 16.0342[/tex]

95th percentile:

X when Z has a pvalue of 0.95, so X when Z = 1.645.

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

[tex]1.645 = \frac{X - 16.1}{0.04}[/tex]

[tex]X - 16.1 = 1.645*0.04[/tex]

[tex]X = 16.1658[/tex]

Between 16.0342 and 16.1658 ounces.

It can be deduced that the probability of the boxes ending up with at least 1 pound of cereal will be 99.38%.

The Z score based on the information will be:

Z = (16 - 16.1) / 0.04

Z = -2.5

Therefore, the p value is 0.0062. The probability will be:

= 1 - 0.0062

= 0.9938

The seventy percent of the boxes will contain less than 16 ounces. The ounces that will be contained in the eighty percent will be:

= -0.84 = (X - 16.1) / 0.04

X = 16

Lastly, the middle 90% of the boxes will be between 16.03 ounces 16.17 ounces.

Step-by-step explanation:

Explanation 1:  A statistical question is a question that can be answered by collecting data that varies. For example, “How old am I?" is not a statistical question, but “How old are the students in my school?” is a statistical question.  Therefore, when we look at the options, the second option is the best.

Explanation 2:  To find the mode we have to find which number is most frequent through out the set.  When we look at the numbers, there are 3 numbers that have 56.  Therefore, 56 is the mode.

Answer:

5.47% of the total variation between the two variables can be explained by the regression line.

Step-by-step explanation:

Given :

R value = 0.234

The R value is the correlation Coefficient ; which gives the type and level of correlation between two variables.

However, to Obtian the percentage variation which can be explained by by the regression line, we have to obtain the Coefficient of determination, R².

R² value is Obtained by taking the squared of the correlation Coefficient

Hence,

R² = 0.234² = 0.054756

R² = 0.05476 * 100% = 5.4756%

Hence, R² = 5.48%

This is interpreted as ; 5.47% of the total variation between the two variables can be explained by the regression line.
