2. Solve for z and express your answer in interval notation: 10 – 4z < 20

Answers

Answer 1

Answer:

z > -5/2

Step-by-step explanation:

Since both sides are divided by a negative number, the equality is switched.

10 - 4z < 20

(10 - 4z) - 10 < 20 - 10

-4z < 10

(-4z)/-4 < 10/-4

z > -5/2

Answer 2

The solution for z will be;

⇒ z ∈ (- 2.5 , ∞ )

What is Inequality?

A relation by which we can compare two or more mathematical expression is called an inequality.

Given that;

The inequality is,

⇒ 10 - 4z < 20

Now,

Since, The inequality is,

⇒ 10 - 4z < 20

Solve for z as;

⇒ 10 - 4z < 20

⇒ 10 - 4z + 4z < 20 + 4z

⇒ 10 < 20 + 4z

⇒ 10 - 20 < 4z

⇒ - 10 < 4z

⇒ - 2.5 < z

⇒ z ∈ (- 2.5 , ∞ )

Thus, The interval notation is,

⇒ z ∈ (- 2.5 , ∞ )

The regression equation is y (with a hat) = ______ + _______
When X is 7 this gives y (with a hat) = _________

Answers

Answer:

yhat=1.36+0.74x

when x=7 then yhat=6.54

Step-by-step explanation:

Th regression equation is

yhat=a+bx

where slope b is

[tex]b=\frac{nsumxy-(sumx)(sumy)}{nsumx^{2}-(sumx)^{2} }[/tex]

and intercept a is

a=ybar-bxbar

x   4   5   2   6    9

y   4   6   2   7    7

xy 16 30  4  42  63

16 25  4  36  81

n=5.

sumx=26.

sumy=26.

sumx²=162.

sumxy=155.

[tex]b=\frac{5*155-(26)(26)}{5*162-(26)^{2} }[/tex]

[tex]b=\frac{99}{134 }[/tex]

b=0.7388

b=0.74 (rounded to 2 decimal places)

xbar=sumx/n=26/5=5.2

ybar=sumy/n=26/5=5.2

a=ybar-b*xbar

a=5.2-0.7388*5.2

a=5.2-3.8418

a=1.3582

a=1.36 (rounded to 2 decimal places)

Thus, the required regression equation is

yhat=1.36+0.74x

When x is 7 this gives yhat

yhat=1.36+0.74*7

yhat=1.36+5.18

yhat=6.54

Suppose a team of doctors wanted to study the effect of different types of exercise on reducing body fat percentage in adult men. The 57 participants in the study consist of men between the ages of 40 and 49 with body fat percentages ranging from 32%â34%. The participants were each randomly assigned to one of four exercise regimens.Ten were instructed to complete 45 min of aerobic exercise four times a week.Eleven were instructed to complete 45 min of anaerobic exercise four times a week.Nine were instructed to complete 45 min of aerobic exercise twice a week and 45 minutes of anaerobic exercise twice a week.Nine were instructed not to exercise at all.All participants were asked to adhere to their assigned exercise regimens for eight weeks. Additionally, to control for the effect of diet on weight loss, the doctors provided the participants with all meals for the duration of the study. After eight weeks, the doctors recorded the change in body fat percentage for each of the participants.The doctors plan to use the change in body fat percentage data in a one-way ANOVA F?test. They calculate the mean square between as MSbetween=11.632991 and the mean square within as MSwithin=1.261143. Assume that the requirements for a one-way ANOVA F?test have been met for this study.Choose all of the correct facts about the F statistic for the doctors' ANOVA test.A. The F statistic increases as the differences among the sample means for the exercise groups increase.B. The F statistic is 0.1084.C. The F statistic has 3 degrees of freedom in the numerator and 35 degrees of freedom in the denominator.D. The F statistic indicates which exercise treatment groups, if any, are significantly different from each other.E. The F statistic has 4 degrees of freedom in the numerator and 38 degrees of freedom in the denominator.F. The F statistic is 9.2242.

Answers

Answer:

A. The F statistic increases as the differences among the sample means for the exercise groups increase.

C. The F statistic has 3 degrees of freedom in the numerator and 35 degrees of freedom in the denominator.

F. The F statistic is 9.2242.

Step-by-step explanation:

Given that

Observations                     Samples                             Total

40-49             10       11              9         9                        39

The degrees of freedom is given by

For numerator= k-1 = 4-1=3

For denominator= n-k= 39-4= 35

F statistic is given by

F= MS between/ MS within

=11.632991 / 1.261143 = 9.2242

Where

Mean Square Between = MS between = 11.632991

Mean Square Within = MS within = 1.261143

Hence the correct choices are  A, C and F

A. The F statistic increases as the differences among the sample means for the exercise groups increase.

C. The F statistic has 3 degrees of freedom in the numerator and 35 degrees of freedom in the denominator.

F. The F statistic is 9.2242.

Suppose we have

Mean Square Between = MS between = 18.632991

Mean Square Within = MS within = 1.261143

Then F statistic would be = 14.77468 > 9.2242

which tells that The F statistic increases as the differences among the sample means for the exercise groups increase.

Answer:

[tex]$x=\frac{25\pi }{12} \text{ and }x=\frac{29\pi }{12}[/tex]

Step-by-step explanation:

Solve

[tex]\log_2(2 \sin x) + \log_2(\cos x) =1[/tex]

in interval [tex]$\left(2\pi, \frac{5\pi}{2} \right)$[/tex]

Remember that logarithms follow:

[tex]f(x\cdot y)=f(x)+ f(y)[/tex]

Therefore

[tex]\log_2(2 \sin x) + \log_2(\cos x) =-1 \implies \log_2(2 \sin x \cdot \cos x) =-1[/tex]

We got a double angle of sine:

[tex]\sin(2x)= 2 \sin x \cos x[/tex]

[tex]\log_2( \sin 2x ) =-1[/tex]

[tex]2^{-1}=\sin 2x[/tex]

[tex]$\frac{1}{2} =\sin 2x$[/tex]

The solutions for it are:

[tex]$2x=\frac{\pi }{6}+2\pi n \text{ and }2x=\frac{5\pi }{6}+2\pi n, \text{ as } n\in \mathbb{Z}$[/tex]

As

[tex]$x=\frac{\pi }{12}+\pi n \text{ and }x=\frac{5\pi }{12}+\pi n, \text{ as } n\in \mathbb{Z}$[/tex]

But we have the interval

[tex]$\left(2\pi, \frac{5\pi}{2} \right)$[/tex]

Therefore, the answer is

Use a power series to approximate the definite integral, I, to six decimal places. 0.1 x arctan(5x) dx 0.

Answers

Answer:

definite integral I = 0.001591  to six decimal places

Step-by-step explanation:

The definite integral is given as:

[tex]\int ^{0.1}_{0} \ x \ arctan (5x) \ dx[/tex]

For arctanx , the power series is in the order [tex]x - \dfrac{x^3}{3}+ \dfrac{x^5}{5}-\dfrac{x^7}{7}+...[/tex]

[tex]arc tan \ x = \sum \limits ^{\infty}_{n=0} \dfrac{(-1)^n \ x ^{2n+1}}{2n +1}[/tex]

The next step is to substitute the value of 5x for x in the above equation;

So,

[tex]arc tan \ (5x) = \sum \limits ^{\infty}_{n=0} \dfrac{(-1)^n \ (5x) ^{2n+1}}{2n +1}[/tex]

To  multiply both sides by (x); we have

[tex]x\ arc tan \ (5x) = x \ \sum \limits ^{\infty}_{n=0} \dfrac{(-1)^n \ 5 ^{2n+1} \times x^{2n+1}}{2n +1}[/tex]

[tex]x\ arc tan \ (5x) = \sum \limits ^{\infty}_{n=0} \dfrac{(-1)^n \ 5 ^{2n+1} \times x^{2n+2}}{2n +1}[/tex]

Taking the integral on both sides with respect to x;

[tex]\int^{0.1}_{0} \ x \ arctan (5x) \ dx = \sum \limits ^{\infty}_{n=0} \dfrac{(-1)^n \ 5^{2n +1}}{2n+1} \ \int ^{0.1}_0 x^{2n+2} \ dx[/tex]

[tex]\int^{0.1}_{0} \ x \ arctan (5x) \ dx = \sum \limits ^{\infty}_{n=0} \dfrac{(-1)^n \ 5^{2n +1}}{2n+1} \ [(0.1)^{2n+3}][/tex]

[tex]\int^{0.1}_{0} \ x \ arctan (5x) \ dx = \sum \limits ^{\infty}_{n=0} \dfrac{(-1)^n \ 5^{2n +1} \times (0.1)^{2n+3} }{(2n+1)(2n+3)}[/tex]

[tex]\int^{0.1}_{0} \ x \ arctan (5x) \ dx = [\dfrac{5 \times (0.1)^3}{1.3}-\dfrac{5^3(0.1)^3}{3.5}+\dfrac{5^5(0.1)^7}{5.7}-\dfrac{5^7(0.1)^9}{7.9}+ ...][/tex]

Hi!

First we need to translate 2 units down. That means we need to subtract 2 from the y value. So now we have (-1,1).

For a 270 degree counterclockwise rotation the rule is to go from (x,y) to (y,-x)

So now we have (1,1). Since they're only asking for the x value, the answer is 1.

Answer:

[1, 1]

Step-by-step explanation:

Translation → [-1, 3] moves down to [-1, 1]

Now, a 90°-clockwise rotation is the exact same as a 270°-counterclockwise rotation, and according to the 270°-counterclockwise rotation [90°-clockwise rotation] rule, you take the y-coordinate, bring it over to your new x-coordinate, and take the OPPOSITE of the x-coordinate and set it as your new y-coordinate:

Extended Rotation Rules

270°-clockwise rotation [90°-counterclockwise rotation] >> (x, y) → (-y, x)

270°-counterclockwise rotation [90°-clockwise rotation] >> (x, y) → (y, -x)

180°-rotation >> (x, y) → (-x, -y)

Then, you perform your rotation:

270°-counterclockwise rotation [90°-clockwise rotation] → [-1, 1] moves to [1, 1]

x=4

Same result obtained when comparing the other pairs of equations.

Answer:

Explanation:

Since it is an equilateral Triangle their sides are the same.

Thus, 4(x - 1) = x + 8 = 2x + 4

But we can take 2 sides to work with:
To solve for x:

4(x - 1) = x + 8
4x - 4 = x + 8
4x - x = 8 + 4
3x = 12
x = 12/3
x = 4

Therefore, x = 4 and the equation involving x is 4(x - 1) = x + 8

PLEASE HELP ME ASAP The average of 16 consecutive odd numbers is 122. Find the smallest odd number. FIRST TO ANSWER GETS BRAINLIEST

Answers

Answer:

107

Step-by-step explanation:

Hello, Let's note n the odd number that we are looking for.

If n is odd, n+1 is even but n+2 is odd again and so on and so forth.

So, the 16 consecutive odd numbers are

n, n+2, n+4, ... n+2k, ,,,, ,n+30

It means that the average is:

[tex]\displaystyle \dfrac{1}{16}(n+(n+2)+...+(n+2k)+...+(n+2*15))\\\\=\dfrac{1}{16}\sum_{k=0}^{k=15} {(n+2k)}\\\\=\dfrac{1}{16}\left(n * 16 + 2 \sum_{k=1}^{k=15} {k} \right)\\\\=\dfrac{1}{16}\left(n * 16 + 2 (\dfrac{15*16}{2}) \right)\\[/tex]

And it must be equal to 122, so we can write.

[tex]\dfrac{1}{16}\left(n * 16 + 2 (\dfrac{15*16}{2}) \right)=122\\\\n+15=122\\\\n = 122-15=107[/tex]

Thank you.

how do i solve this absolute value equation
2|5x|= 10?

Answers

Answer:

x=1    x = -1

Step-by-step explanation:

2|5x|= 10

Divide each side by 2

2/2|5x|= 10/2

|5x|= 5

Absolute values have 2 solutions, one positive and one negative

5x = 5      5x = -5

Divide each side by 5

5x/5 = 5/5      5x/5 = -5/5

x = 1                 x = -1

Answer:

Step-by-step explanation:

● 2|5x| = 10

● 2 × |5| ×x = 10

5 is positive so |5| = 5

● 2×5× |x| = 10

● 10×|x| = 10

● |x| = 10

● x = 1 or x = -1

a pharmaceutical salesperson receives a monthly salary of $5000 plus a commission of 7% of sales. write a linear equation for the salesperson’s monthly wage W in terms of monthly sales S. NEED TO TURN IT IN TODAY

Answers

Equation for the monthly wage will be → W = 0.07S + 5000

   Given in the question,

Monthly salary of the sales-person = $5000Commission = 7% of total sales

Let the total sales of a month = $S

Therefore, commission on this sale = 7% of $S

                                                            = $0.07S

Salary of the month = $5000

Total earnings (W) of the sales person = $(0.07S + 5000)

     Therefore, equation for the monthly wage will be,

W = 0.07S + 5000
