Which of the following ordered pairs are y-intercepts? Check all that apply
Varvara68 [4.7K]

A y-intercept is the value at which x = 0.

(4,0) is not a y-intercept because x = 4.

(-1, 1) is not a y-intercept because x = -1.

(0,0) is a y-intercept because x = 0.

(0, -7) is a y-intercept because x = 0.

(-2, 2) is not a y-intercept because x = -2.

(0, -0.25 is a y-intercept because x = 0.

Write the following expression with as few symbols as possible, using the notational conventions:
My name is Ann [436]

Answer:

The simplified expressions are (<em>x</em> + <em>y·</em>z' + <em>t</em>) and <em>x·</em>(<em>x</em> + <em>y</em>' + <em>z</em>) respectively.

Step-by-step explanation:

The expressions provided are:

(i)\ x+((y\times (z')) +t)\\\\(ii)\ x\times((x+(y'))+z)

(i)

Simplify the first expression with as few symbols as possible:

x+((y\times (z')) +t)=x+(yz'+t)

                              =x+yz'+t

(ii)

Simplify the second expression with as few symbols as possible:

x\times((x+(y'))+z)=x\times ((x+y')+z)

                              =x (x+y'+z)

Thus, the simplified expressions are (<em>x</em> + <em>y·</em>z' + <em>t</em>) and <em>x·</em>(<em>x</em> + <em>y</em>' + <em>z</em>) respectively.

The accounting department analyzes the variance of the weekly unit costs reported by two production departments. A sample of 16
Sergio [31]

Answer:

We can conclude that the result is significant and production differ in cost variance.

Step-by-step explanation:

Given :

n1 = 16

n2 = 16

s1² = 5.7

s2² = 2.8

α = 0.10

H0 : σ1² = σ2²

H1 : σ1² ≠ σ2²

The test statistic :

Ftest = s1² / s2² =

Ftest = 5.7 / 2.8

Ftest = 2.036

Using the Pvalue from Fratio calculator :

df numerator = 16 - 1 = 15

df denominator = 16 - 1 = 15

Pvalue(2.036, 15, 15) = 0.0898

Pvalue = 0.0898

Since the Pvalue is < α ; We can conclude that the result is significant and production differ in cost variance.

Annie found that 57 students in her school knew French and 23 of those students knew Spanish, as well. There were 11 students wh
V125BC [204]

Answer:

Table C is the correct option.

Step-by-step explanation:

We are given,

Number of students which knew French = 57

Number of students which knew both French and Spanish  = 23

Number of students which knew Spanish but not French = 11

Number of students which knew neither French nor Spanish = 4

So, we get that,

Number of students not knowing French = 57 - 23 = 34

Hence, the table for the given situation is,

                              Knew Spanish    Did not know Spanish    Total

Knew French                  23                          34                         57

Did not know French      11                             4                           15

Total                               34                             38                        72

Thus, option C is correct.
