Answer:

my cash app is Joy95H Suppose we wish to find the zeros of f(x) = x

3 + 4x

2 − 5x − 14. Setting f(x) = 0 results in the

polynomial equation x

3 + 4x

2 − 5x − 14 = 0. Despite all of the factoring techniques we learned1

in Intermediate Algebra, this equation foils2 us at every turn. If we graph f using the graphing

calculator, we get

The graph suggests that the function has three zeros, one of which is x = 2. It’s easy to show

that f(2) = 0, but the other two zeros seem to be less friendly. Even though we could use the

‘Zero’ command to find decimal approximations for these, we seek a method to find the remaining

zeros exactly. Based on our experience, if x = 2 is a zero, it seems that there should be a factor

of (x − 2) lurking around in the factorization of f(x). In other words, we should expect that

x

3 + 4x

2 − 5x − 14 = (x − 2) q(x), where q(x) is some other polynomial. How could we find such

a q(x), if it even exists? The answer comes from our old friend, polynomial division. Dividing

x

3 + 4x

2 − 5x − 14 by x − 2 gives

x

2 + 6x + 7

As you may recall, this means x

3 + 4x

2 − 5x − 14 = (x − 2)

x

2 + 6x + 7

, so to find the zeros of f,

we now solve (x − 2)

x

2 + 6x + 7

= 0. We get x − 2 = 0 (which gives us our known zero, x = 2)

as well as x

2 + 6x + 7 = 0. The latter doesn’t factor nicely, so we apply the Quadratic Formula to

get x = −3 ±

According to the empirical rule -

a) About 95% of organs will be in range of weights of organs 230 grams and 430 grams.

b) 68% percentage of organs weighs between 280 grams and 380 grams.

c) 32% percentage of organs weighs less than 280 grams or more than 380 grams.

d) 97.35% percentage of organs weighs between 180 grams and 430 grams.

What is empirical rule?

The empirical rule 68-95-99.7 tells us that:

68% of the data is expected to be within 1 standard deviation from the mean.

95% of the data is expected to be within 2 standard deviation from the mean.

99.7% of the data is expected to be within 3 standard deviation from the mean.

There is a bell shaped distribution ( assume as approximately normal) with mean of 330 g and standard deviation of 50 g.

a) This happens for an interval with ±2 standard deviations from the mean.

That is:

X1 = μ + z1 × σ                  X2 = μ + z2 × σ

X1 = 330 - 2 × 50             X2 = 330 + 2 × 50

X1 = 330 - 100                  X2 = 330 + 100

X1 = 230                           X2 = 430

Therefore, the range of weights of organs is 230 grams and 430 grams.

b) Calculate the z-scores for each value to know how many standard deviations are from the mean.

z1 = (x1 - μ)/σ                   z2 = (x2 - μ)/σ

z1 = (280 - 330)/50        z2 = (380 - 330)/50

z1 = -50/50                     z2 = 50/50

z1 = -1                              z2 = 1  

The values are 1 standard deviations from the mean each.

Therefore, the expected percentage is 68%.

c) This is the complementary of the point b.

Then, it is expected that (100 - 68)% = 32% of the organs weigh less than 280 grams or more than 380 grams.

d) Calculate the z-scores for each value to know how many standard deviations are from the mean.

z1 = (x1 - μ)/σ                   z2 = (x2 - μ)/σ

z1 = (180 - 330)/50        z2 = (430 - 330)/50

z1 = -150/50                     z2 = 100/50

z1 = -3                              z2 = 2  

The values are 1 standard deviations from the mean each.

Therefore, the expected percentage is 68%.

The values are 3 standard deviations from the mean each. Between 180 and 330 there is 99.7%/2 = 49.85% of the data.

The values are 2 standard deviations from the mean each. Between 330 and 430 there is 95%/2 = 47.5% of the data.

Then, between 180 grams and 430 grams there is (49.85% + 47.5)% = 97.35% of the data.

Therefore, the expected percentage is 97.35%.

In order for the relationship zyx ~ wvu to be correct, the following conditions must be true:

Corresponding angles are congruent: The angles formed by matching vertices should have the same measures in both triangles. This ensures that the corresponding angles are equivalent.

Corresponding sides are proportional: The lengths of the sides that connect the corresponding vertices of the triangles should have a consistent ratio. This implies that the corresponding sides are proportional to each other.

These conditions are based on the definition of similarity between two triangles. If both the corresponding angles are congruent and the corresponding sides are proportional, then the triangles zyx and wvu are considered similar (denoted by ~).

Therefore, in order for zyx ~ wvu to be correct, the congruence of corresponding angles and the proportionality of corresponding sides must hold true.

The number of comedy DVDs will be equal to 604.

The percentage is defined as representing any number with respect to 100. It is denoted by the sign %. The percentage stands for "out of 100." Imagine any measurement or object being divided into 100 equal bits.

Given that the total number of DVDs are 1830 and the percentage of comedy DVDs is 33%.

The number of comedy DVDs will be calculated as,

N = ( 1830 x 33%)

N = (1830 x 33 ) / 100

N = 604

A sequence of transformations that maps quadrilateral MATH onto quadrilateral M"A"T"H" is a rotation of 180° about the origin and a translation by 1 unit left and 1 unit up.

In Mathematics and Geometry, the rotation of a point 180° about the origin in a clockwise or counterclockwise direction would produce a point that has these coordinates (-x, -y).

Additionally, the mapping rule for the rotation of a geometric figure 180° counterclockwise about the origin is given by this mathematical expression:

(x, y)                                            →            (-x, -y)

Coordinates of point M (2, 4)  →  Coordinates of point M' = (-2, -4)

By applying a translation to the image (M') vertically upward by 1 unit and horizontally left by 1 unit, the new coordinate M" of quadrilateral M"A"T"H" include the following:

(x, y)                               →                  (x - 1, y + 1)

Given,

     A solid is created by revolving a curve f(x) around the y-axis.

We know that,

The volume of a solid that is rotated around the y-axis is  calculated using the "Disk Method"

The disk method is generally used when we rotate a particular curve around the x-axis or y-axis.

The volume of the solid that is formed by revolving the region bounded by the curve  \(x = F(y)\) and the y-axis between  \(y=c\)  and \(y = d\)  about the y-axis is given by:

                         \(V = \pi \int\ {dc[F(y)]} \, 2dy\)

a) The inequality for the expression 2z + 9 is 2z + 9 > 13.

b) The inequality for the expression 3(z - 4) is 3z - 12 > -6.

c) The inequality for the expression 4 + 2z is 4 + 2z > 8.

d) The inequality for the expression 5(3z - 2) is 15z - 10 > 20.

a) To write an inequality for the expression 2z + 9, we can multiply the given inequality z > 2 by 2 and then add 9 to both sides of the inequality:

2z > 2 * 2

2z > 4

Adding 9 to both sides:

2z + 9 > 4 + 9

2z + 9 > 13

Therefore, the inequality for the expression 2z + 9 is 2z + 9 > 13.

b) For the expression 3(z - 4), we can distribute the 3 inside the parentheses:

3z - 3 * 4

3z - 12

Since we are given that z > 2, we can substitute z > 2 into the expression:

3z - 12 > 3 * 2 - 12

3z - 12 > 6 - 12

3z - 12 > -6

Therefore, the inequality for the expression 3(z - 4) is 3z - 12 > -6.

c) The expression 4 + 2z does not change with the given inequality z > 2. We can simply rewrite the expression:

4 + 2z > 4 + 2 * 2

4 + 2z > 4 + 4

4 + 2z > 8

Therefore, the inequality for the expression 4 + 2z is 4 + 2z > 8.

d) Similar to the previous expressions, we can distribute the 5 in the expression 5(3z - 2):

5 * 3z - 5 * 2

15z - 10

Considering the given inequality z > 2, we can substitute z > 2 into the expression:

15z - 10 > 15 * 2 - 10

15z - 10 > 30 - 10

15z - 10 > 20

Therefore, the inequality for the expression 5(3z - 2) is 15z - 10 > 20.

We cannot conclude that whether a subject lies or does not lie is independent of the polygraph test indication.

The test statistic needed to test the claim that whether a subject lies or does not lie is independent of the polygraph test indication is the chi-square statistic.

In this case, the grand total is 90. The row totals are 57 and 33, and the column totals are 42 and 48. The expected frequencies are as follows:

The chi-square statistic is calculated as 0.177. The p-value for the chi-square statistic is calculated using a chi-square table. The degrees of freedom for the chi-square table are the number of rows minus 1, multiplied by the number of columns minus 1.

Since the p-value is greater than 0.05, we fail to reject the null hypothesis. We cannot conclude that whether a subject lies or does not lie is independent of the polygraph test indication.
