Answer:

The t critical value at 0.05 significance level for df=n-1=17-1=16 is:

t_{critical}=\pm2.120

Step-by-step explanation:

We are given confidence level =0.95

n=17

Significance level = 1 - confidence level

                              = 1 - 0.95

                               = 0. 05

Degrees of freedom = n - 1 = 17 - 1 = 16

Therefore, using the t distribution table, the t critical values are:

t_{critical} = \pm 2.120

Step-by-step explanation:

conditional :

3-2x ≥ 0

-2x ≥-3

x ≤ 3/2

1-x ≥ 0

-x≥ -1

x ≤ 1

so, the domain is:

{ x | x € the Real numbers, x ≤ 1}

XY and BD are parallel lines
madreJ [45]

Answer:

a) they are corresponding angles

b) B=55° (proven)

C=55 (Angles opposite equal sides)

B+C+X=180° ( sum of angles of a triangle)

55°+55°X=180

110°+X=180°

X=180°-110°

X=70°

6. (5 points) Graph using two intercepts; show your work in finding the intercepts. 6x - 3y = 18
Setler [38]

Answer:

Divide both sides by 18. The new coefficients will be the reciprocals of the intercepts:

6x-3y=18 \rightarrow \frac6{18}x - \frac3{18}y = 1 \rightarrow \frac x3-\frac y6 =1 The two intercepts are then 3 and -6.

(I know, dividing by 3 both sides of the equations would have made the whole process way easier).

Alternatively, plug x = 0 to find the y intercept and y=0 to find the x intercept. Either way the graph will look something like the one I'm sketching on paint.
