The General Social Survey asked a large number of people how much time they spent watching TV each day. The mean number of hours
DerKrebs [107]

Answer:

Yes, we can conclude that the population standard deviation of TV watching times for teenagers is less than 2.66

Step-by-step explanation:

H0 : σ² = 2.66²

H1 : σ² < 2.66²

X²c = (n - 1)*s² ÷ σ²

sample size, n = 40

Sample standard deviation, s = 1.9

X²c = ((40 - 1) * 1.9²) ÷ 2.66²

X²c = 140.79 ÷ 7.0756

X²c = 19.897

Using a confidence level of 95%

Degree of freedom, df = n - 1 ; df = 40 - 1 = 39

The critical value using the chi distribution table is 25.6954

Comparing the test statistic with the critical value :

19.897 < 25.6954

Test statistic < Critical value ; Reject the Null

Hence, we can conclude that the population standard deviation of TV watching times for teenagers is less than 2.66

Bogdan [553]

Answer:

S=32 D=34

Step-by-step explanation:

{-----------------VARIABLES------------}

D=Drake

S=Stephanie

TA=Total Age

{----------------GIVEN/EQUATIONS-------------}

D=S+2

TA=D+2s

{--------------SUB/SOLVE---------------}

98=D+2S

SUB FOR D

98=3S+2

96=3S

S=32

D=S+2

D=34

Give a rule of the​ piecewise-defined function. Give the domain and the range.
dimulka [17.4K]

Answer:

Hello your question is incomplete below is the complete question

option B is correct  

f(x) = 1 if x ≤ 0

       -2 if x > 0

Step-by-step explanation:

The Rule of the piece-wise-defined function is :

from the given figure attached it can be seen that as : x ≤ 0 , y = 1

while for x > 0 , y = -2

therefore option B is correct  

f(x) = 1 if x ≤ 0

       -2 if x > 0

(X,3) , (5,9) slope=2
maxonik [38]
Equation for slope.
y2 - y1/x2 - x1
Using (x,3) and (5,9)
9 - 3/5 - x = 2
6/(5 - x) = 2
Cross multiply
6 = 2(5 - x)
6 = 10 - 2x
6 - 10 = -2x
-4 = -2x
x = 2
y2 - y1/x2 - x1
9 - 3/5 - 2
6/3 = 2
Hope this helps.
:-)
