Answer:

Difference = \frac{13}{40}

Step-by-step explanation:

Given

Thursday = \frac{3}{8}\ mile

Tuesday = \frac{7}{10}\ mile

Required

How much farther is she on Tuesday

To do this, we simply calculate the difference between distance covered on both days.

Difference = Tuesday-Thursday

Difference = \frac{7}{10} -  \frac{3}{8}

Take LCM

Difference = \frac{28- 15}{40}

Difference = \frac{13}{40}

<em>Hence, she ran 13/40 mile farther on Tuesday</em>

Answer:

The degrees of freedom associated with the critical value is 25.

Step-by-step explanation:

The number of values in the final calculation of a statistic that are free to vary is referred to as the degrees of freedom. That is, it is the number of independent ways by which a dynamic system can move, without disrupting any constraint imposed on it.

The degrees of freedom for the t-distribution is obtained by substituting the values of n1​ and n2​ in the degrees of freedom formula.

Degrees of freedom, df = n1​+n2​−2

                                       = 15+12−2=27−2=25​

Therefore, the degrees of freedom associated with the critical value is 25.

Answer:

The change in the area of the rectangle is 0 square feet

Step-by-step explanation:

To solve this problem we have to calculate the area of ​​the two rectangles that give us

first we have to know the formula to calculate the area of ​​a rectangle

a = area

l = length  = 12ft

w = width = 5ft

a = l * w

we replace the known walues

a = 12ft * 5ft

a = 60ft²

we do the same with the other rectangle, but first we have to calculate its sides

w = 5ft - (5ft * 20/100)

w = 5ft - 1ft

w = 4ft

l = 12ft + (12ft * 25/100)

l = 12ft + 3ft

l = 15ft

a2 = 15ft * 4ft

a2 = 60ft²

to calculate the change in the area we subtract (a - a2)

a - a2 =

60ft² - 60ft² = 0ft²

Graph the set of points. Which model is most appropriate for the set?
Tamiku [17]
Check the slope between the moving points 

<span>slope between (–6, –1) & (–3, 2) = 1 </span>
<span>slope between (-3, 2) & (–1, 4) = 1 </span>
<span>slope between (-1, 4) & (2, 7) = 1 </span>

<span>the points are collinear and make an angle of 45 degrees with the x-axis </span>

<span>we can have an equation of a line passing through (-6,-1) and slope 1 as </span>

<span>(y + 1) = 1(x + 6) </span>
<span>y = x + 5 is your linear model mostly</span>
