Choose the graph of the following function: f(x) =-2 sin(x)

Answer:

The wife IQ is 103 when the husband IQ is 100.

Step-by-step explanation:

The given equation of the regression line is y = -11 + 1.14x, where x represents the IQ score of the husband.

If the husband IQ is 100 the the wife IQ is

y = -11 + 1.14x,

y = -11 + 1.14(100)

y = -11 + 114

y = 103

Answer:

The integer is 1

Step-by-step explanation:

Required

Translate and solve

Let the positive integer be x.

So, we have;

The square of the integer is: x^2

Plus 5 times its consecutive integer is: x^2 + 5(x + 1)

Equals 11 is: x^2 + 5(x + 1) = 11

So, we have:

[tex]x^2 + 5(x + 1) = 11[/tex]

Open bracket

[tex]x^2 + 5x + 5= 11[/tex]

Subtract 11 from both sides

[tex]x^2 + 5x -6= 0[/tex]

Expand

[tex]x^2 + 6x - x-6= 0[/tex]

Factorize:

[tex]x(x + 6) - 1(x+6)= 0[/tex]

Factor out x + 6

[tex](x - 1) (x+6)= 0[/tex]

Split

[tex]x - 1 = 0\ or\ x + 6 = 0[/tex]

Solve for x in both cases

[tex]x = 1\ or\ x = -6[/tex]

Since the number is positive, then [tex]x = 1[/tex]

Answer:

1.) up

2.) (-2,-5)

3.) x = -2

4.) (-2,-5)

5.) y = -5

6.) -∞ < x < ∞

7.) -5 < y < ∞

8.) (0,0)

9.) (0,0) and (-4,0)

10.) two solutions

Step-by-step explanation:

1.) because the parabola opens upward and the vertex is down

2.) the lowest point of the parabola is (-2,-5)

3.) If a line was drawn through the point x = -2, the two halves of the parabola would look symmetrical ( the same on both sides).

4.) The minimum point on the graph is ( -2,-5), because that is the lowest point on this upward parabola, and we can not determine the maximum.

5.) The minimum value of y is y = -5, because that is the lowest value of y on this graph, and we can not determine the maximum.

6.) Because the arms of the parabola continue traveling through negative infinity and positive infinity on the x-axis, the domain is -∞ < x < ∞.

7.) The arms of the parabola go from y = -5 to infinity, so the range of the parabola is -5 < y < ∞.

8.) The parabola first crosses the y-axis at the point (0,0)

9.) The parabola first crosses the x-axis at the points (0,0) and (-4,0)

10,) The solution to the parabola is the variable x. The solutions (x intercepts) of the parabola are x = 0 and x = -4.

Answer: 1.25

Step-by-step explanation:

Answer:

0.9332 = 93.32% probability that the mean of the sample will be less than 12.1 ounces.

Step-by-step explanation:

To solve this question, we need to understand the normal probability distribution and the central limit theorem.

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.

Central Limit Theorem

The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].

For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.

Mean of 12 ounces and a standard deviation of 0.2 ounces.

This means that [tex]\mu = 12, \sigma = 0.2[/tex]

Sample of 9:

This means that [tex]n = 9, s = \frac{0.2}{\sqrt{9}}[/tex]

Find the probability that the mean of the sample will be less than 12.1 ounces.

This is the pvalue of Z when X = 12.1. So

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

By the Central Limit Theorem

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

[tex]Z = \frac{12.1 - 12}{\frac{0.2}{\sqrt{9}}}[/tex]

[tex]Z = 1.5[/tex]

[tex]Z = 1.5[/tex] has a pvalue of 0.9332

0.9332 = 93.32% probability that the mean of the sample will be less than 12.1 ounces.

Answer:

C) 2

Step-by-step explanation:

Emma: Range  = 8

Arianna: Range = 6

The difference in the range is 2 (8-6)

Answer:

C) 2

Step-by-step explanation:

Emma:

Max = 20

Min = 12

Range = 20 - 12

Range = 8

Arianna:

Max = 18

Min = 12

Range = 18 - 12

Range = 6

Difference between the 2 ranges:

8 - 6 = 2

Answer:

20 - 6x = 4x - 15

35 - 6x = 4x

35 = 2x

x = 15.5

The solution to the equation 20 - 6x = 4x -15 is x = 3.5.

To solve the equation 20 - 6x = 4x - 15,

20 - 6x = 4x - 15

To isolate the variable terms on one side,  add 6x to both sides:

20 - 6x + 6x = 4x - 15 + 6x

20 = 10x - 15

Next, add 15 to both sides to further isolate the variable term:

20 + 15 = 10x - 15 + 15

35 = 10x

Finally, divide both sides by 10 to solve for x:

35/10 = 10x/10

3.5 = x

Therefore, the solution to the equation is x = 3.5.

Answer:

a)[tex]X=((-15-\sqrt{201},(-15+\sqrt{201}),(0,\infty)[/tex]

b)[tex]Y=(\infty,\frac{1}{2}(-15-\sqrt{201} ) ),(\frac{1}{2}()-15+\sqrt{201)},0 )[/tex]

Step-by-step explanation:

From the question we are told that

The Function

[tex]f(x)=1+\frac{1}{x} +\frac{5}{x^2} +\frac{1}{x^3}[/tex]

Generally the differentiation of function f(x) is mathematically solved as

[tex]f(x)=1+\frac{1}{x} +\frac{5}{x^2} +\frac{1}{x^3}[/tex]

[tex]f(x)=\frac{x^3+x^2+5x+1}{x^2}[/tex]

Therefore

[tex]f'(x)=\frac{x^2+10x+3}{x^4}[/tex]

Generally critical point is given as

[tex]f'(x)=0[/tex]

[tex]\frac{x^2+10x+3}{x^4}=0[/tex]

[tex]x=-5 \pm\sqrt{22}[/tex]

Generally the maximum and minimum x value for critical point is mathematically solved as

[tex]f'(-5 \pm\sqrt{22})[/tex]

Where

Maximum value of x

[tex]f'(-5 +\sqrt{22})<0[/tex]

Minimum value of x

[tex]f'(-5 +\sqrt{22})<0[/tex]

Therefore interval of increase is mathematically given by

[tex]f'(-5 -\sqrt{22}),f'(-5 +\sqrt{22})[/tex]

[tex]f(x)<0,-\infty<x<(f'(-5 -\sqrt{22})) ,(f'(-5 +\sqrt{22}))<x<0,0<x< \infty[/tex]

Therefore interval of decrease is mathematically given by

[tex](-\infty,-5 -\sqrt{22}),f'(-5 +\sqrt{22},0),(0,\infty)[/tex]

Generally the second differentiation of function f(x) is mathematically solved as

[tex]f''(x)=\frac{2(x^2+15x+6)}{x^5}[/tex]

Generally the point of inflection is mathematically solved as

[tex]f''(x)=0[/tex]

[tex]x^2+15x+6=0[/tex]

Therefore inflection points is given as

[tex]x=\frac{1}{2} (-15 \pm \sqrt{201}[/tex]

[tex]f''(x)>0,\frac{1}{2}(-15-\sqrt{201}) <x<\frac{1}{2}(-15-\sqrt{201}) <x<0[/tex]

a)Generally the concave upward interval X is mathematically given as

[tex]X=((-15-\sqrt{201},(-15+\sqrt{201}),(0,\infty)[/tex]

[tex]f''(x)<0,-\infty<x<\frac{1}{2}(-15-\sqrt{201}) , \frac{1}{2}(-15-\sqrt{201}) <x<0[/tex]

b)Generally the concave downward interval Y is mathematically given as

[tex]Y=(\infty,\frac{1}{2}(-15-\sqrt{201} ) ),(\frac{1}{2}()-15+\sqrt{201)},0 )[/tex]
