Step-by-step explanation:

Answer:

The new median would be 15.

Step-by-step explanation:

This is because the median means the middle number so we can cross out 2 and 25. Then cross out 6 and 23. Then cross out 7 and 21. Next, cross out 14 and 20. Since there is only one number left, 15, that number is therefore the median.

Answer:

List the numbers in order including 25

2,6,7,14,15,20,21,23,25

choose the number in the middle

15 has 4 numbers to the left and right so it is in the middle so it is the median

[tex]-0.245 \pm2.160(0.205)[/tex]

Step-by-step explanation:

After working this way for 6 months he takes a simple random sample of 15 days. He records how long he walked that day (in hours) as recorded by his fitness watch as well as his billable hours for that day as recorded by a work app on his computer.

Slope is -0.245

Sample size  n = 15

Standard error is 0.205

Confidence level 95

Sognificance level is (100 - 95)% = 0.05

Degree of freedom is n -2 = 15 -2 = 13

Critical Value =2.16 = [using excel = TINV (0.05, 13)]

Marginal Error = Critical Value * standard error

= 2.16 * 0.205

= 0.4428

[tex]-0.245 \pm2.160(0.205)[/tex]

Answer:

The correct answer is C. [-0.245±2.160*0.205]

Step-by-step explanation:

Hello!

To analyze the if walking while working (independent variable X) affects his working productivity (dependent variable Y) James took a random sample of 15 days (from a 6 month period in which he worked and trained at home) and recorded how long he walked and his billable hours for that day.

Using this information he estimated the linear regression between the working productivity and the time spent training.

^Y= 7.785 -0.245X

The interest is to estimate the change in the average number of billable hours every time he increases the time spent walking in 1 hour.

To estimate the range of values the average billable hours may take each time the training time increases sone hour, you have to calculate a confidence interval for the population slope of the regression. The statistic is a t-test:

[tex]t= \frac{b-\beta}{Sb} ~~t_{n-1}[/tex]

[b±[tex]t_{n-2;1-\alpha /2}[/tex]*Sb]

Using a 95% confidence level the value of t is [tex]t_{n-2;1-\alpha /2}= t_{13; 0.975}= 2.160[/tex]

b= -0.245

Sb= 0.205

[-0.245±2.160*0.205]

[-0.68780.1978]

Using a 95% confidence level you'd expect the interval [-0.68780.1978] to contain the value of the average billable hours when the time spent walking increases in 1 hour.

I hope this helps!

Answer: 10^3

Step-by-step explanation:

Since the problem is displayed at [tex](10^1)^3[/tex], you see that there is a parenthesis separating the [tex]10^1[/tex] and the 3. In long story short, if you see a parenthesis, if means to multiply.

[tex]10^1^*^3=10^3[/tex]

In slope-intercept form, we have these values (y = mx + b):

m = slope

b = y-intercept

Change the equation from standard form to slope-intercept form.

-9x + 7y = 28

-9x + 9x + 7y = 28 + 9x

7y = 28 + 9x

7y/7 = 28/7 + 9x/7

y = 4 + 9/7x

y = 9/7x + 4

Therefore, the y-intercept is 4.

Best of Luck!

Answer:

The area of the shape is [tex]A=886 \:cm^2[/tex].

Step-by-step explanation:

The shape in the graph is a composite figure is made up of several simple geometric figures such as triangles, and rectangles.

Area is the space inside of a two-dimensional shape. We can also think of area as the amount of space a shape covers.

To calculate the area of a composite shape you must divide the shape into rectangles, triangles or other shapes you can find the area of and then add the areas back together.

First  separate the composite shape into three simpler shapes, in this case two rectangles and  a triangle. Then find the area of each figure.

To find the area of a rectangle, we multiply the length of the rectangle by the width of the rectangle.

The area of the first rectangle is [tex]A=34\cdot 16=544\:cm^2[/tex]

The area of the second rectangle is [tex]A=11\cdot19=209\: cm^2[/tex]

The area of a triangle is given by the formula [tex]A=\frac{1}{2} bh[/tex] where b is the base and h is the height of the triangle.

The area of the triangle is [tex]A=\frac{1}{2} \cdot 14\cdot19=133\:cm^2[/tex]

Finally, add the areas of the simpler figures together to find the total area of the  composite figure.

[tex]A_{composite\:shape}=544+209+133=886 \:cm^2[/tex]

Answer:2t-7

i just kinda solved it hehe

The (2t - 7) is the expression that is equivalent to (2(t-4)+1) and this can be determined by using the arithmetic operations.

Given :

Expression - 2(t - 4) + 1

The following steps can be used to evaluate the given expression:

Step 1 - Open the parenthesis in the given expression. Then multiply 2 by t and then multiply 2 by -4.

= 2t - 8 + 1

Step 2 - Now, subtract 8 from 1 in the above expression.

= 2t - 7

So, the (2t - 7) is the expression that is equivalent to (2(t-4)+1).

Answer:

  y = x^2 +2x +1

Step-by-step explanation:

Let's see how this works.

Two of the given points have the same y-value, so the axis of symmetry is located halfway between. If we translate the desired curve down 1 unit, those symmetrical values become zeros, and our function will look like ...

  f(x) = ax(x +2)

We want this to go through the third point, also translated down by 1 unit, so we have ...

  3 = a(1)(1+2) = 3a

That is, a=1, so f(x) = x(x+2) and translating that up 1 unit gives our desired function:

  y = x(x+2) +1

  y = x^2 +2x +1

_____

Using the quadratic regression function of a graphing calculator gives the same result.

Comment on the solution approach

For arbitrary points, one would generally substitute them into the formula for  the function you want:

  y = ax^2 +bx +c

to get three equations in the parameters a, b, and c. These equations would be solved to find the desired coefficients. As noted elsewhere, one of the given points for this problem is the y-intercept (0, 1), so right away we know c = 1. ("c" is the y-intercept.)

That leaves two remaining equations in two unknowns (using the other two points).

Using the point (-2, 1), the equation is ...

  1 = a(-2)^2 +b(-2) +1   ⇒   4a - 2b = 0   ⇒   2a -b = 0

Using the point (1, 4), the equation is ...

  4 = a(1^2) +b(1) +1   ⇒   a +b = 3

Adding these gives 3a = 3, or a=1. Then substitution gives b=2, so the final equation is ...

  y = x^2 +2x +1

Answer:

a = 3, b = 6, c = 5

Step-by-step explanation:

[tex] {3}^{ \frac{6}{5} } = \sqrt[5]{ {3}^{6} } \\ equating \: it \: with \\ \sqrt[c]{ {a}^{b} } \: we \: find : \\ a = 3 \: \: b = 6 \: \: c = 5 \\ [/tex]

Answer:

35

Step-by-step explanation:

Equation:

(-6/5)x - 4 = -46

Add 4 on both sides:

(-6/5)x - 4 = -46

           +4     +4

(-6/5)x = -42

Multiply both sides by the reciprocal, or opposite:

-5/6[(-6/5)x] = (-42)-5/6

x = 35

Therefore, x is equal to 35.

Answer:

Patel’s initial deposit was $3000

Step-by-step explanation:

Given:

Simple interest (S.I.) = 5%

Time period (t) = 10 years

Interest earned (r) = $1500

To find: Patel’s initial deposit

Solution:

Simple interest is a method of calculating the interest charged on the principal, or original amount of a loan.

Let p denotes original amount of a loan

[tex]S.I.=\frac{p\times r\times t}{100}\\\Rightarrow 1500=\frac{p\times 5\times 10}{100}\\\Rightarrow p=\frac{1500\times 100}{5\times 10}\\=3000[/tex]

So, Patel’s initial deposit was $3000

t = 2

so the answer is b?

it shows many numbers.

2t = 4 [simplify]

divide both sides by 2

2t/2 = 4/2

so t = 2, but i see that theres a 9 on b? is that an accident?

Answer:

n =2

Step-by-step explanation:

Compound interest:

The compound interest formula is given by:

[tex]A(t) = P(1 + \frac{r}{n})^{nt}[/tex]

Where A(t) is the amount of money after t years, P is the principal(the initial sum of money), r is the interest rate(as a decimal value), n is the number of times that interest is compounded per year and t is the time in years for which the money is invested or borrowed.

In this question:

The money is compounded every 6 months.

n is the number of times that interest is compounded per year.

Each 6 months means 12/6 = twice a year. So n =2..
