Answer:
There is convincing evidence that less than 40% of US households plan to purchase television in the next two years.
Null hypothesis H•= 40%
Alternative Hypothesis Hi < 40%
Step-by-step explanation:
Null hypothesis H•= 40%
From the survey, percentage of household that responded that they plan to buy new television in the next two years is given by
= 374/1010 × 100%
= 37%
Therefore,
Alternative Hypothesis Hi<40%
Hence, there is convincing evidence that less than 40% of US households plan to purchase television in the next two years. Since both null and alternative Hypothesis are less than or equal to 40%.

the temperature dropped 5 degrees in four hours
Step-by-step explanation:
Answer:
p=114
Step-by-step explanation:
Let K=m/p=8/3 proporcionality constant. if m=304 then p=?
m/p=8/3; 8/3=m/p; p(8/3)=m; p=(3/8)m; replacing m we have p=304(3/8) finally p=114
Answer:
x = 1 y= 3
Step-by-step explanation:
Multiply each equation by the value that makes the coefficients of y opposite.
Simplify.
Add the two equations together to eliminate y from the system.
Divide each term by 8 and simplify.
Substitute the value found for x into one of the original equations, then solve for y.
The result can be shown in multiple forms.
Point Form:
(1,3)
Equation Form:
x=1 ,y=3

Answer:
PT= 130
Step-by-step explanation:
Since T is the midpoint of segment PQ,
PT = TQ
7x - 24 = 6x-2
Subtract 6x both sides and add 24 both sides
7x -6x - 24 = 6x -6x -2
x - 24 + 24 = -2 + 24
x= 22
Substitue x into PT
7(22) - 24
154 - 24
PT= 130
