Answer:
Step-by-step explanation:
Rewrite the equation into y=mx+b form by rearranging terms using inverse operations.
17x + 11y = 17 Subtract 17x from both sides.
-17x -17x
---------------------------
11y = 17 - 17x Divide by 11 on both sides.
y = 17/11 - 17/11 x
The slope intercept form is .
Answer:
Null hypothesis: ,
Alternative hypothesis:
Step-by-step explanation:
Previous concepts
A hypothesis is defined as "a speculation or theory based on insufficient evidence that lends itself to further testing and experimentation. With further testing, a hypothesis can usually be proven true or false".
The null hypothesis is defined as "a hypothesis that says there is no statistical significance between the two variables in the hypothesis. It is the hypothesis that the researcher is trying to disprove".
The alternative hypothesis is "just the inverse, or opposite, of the null hypothesis. It is the hypothesis that researcher is trying to prove".
Solution to the problem
Some Notation
represent the proportion of the news media that is Democrat
represent the proportion of the public that is Democrat
On this case the claim that they want to test is: "That a larger proportion of members of the news media are Democrats when compared to the general public". So we want to check if the population proportion p1 is higher than p2, so this needs to be on the alternative hypothesis and on the null hypothesis we need to have the complement of the alternative hypothesis.
Null hypothesis:
Or
The null hypothesis can be on this way: , but is better put the complement of the alternative hypothesis.
Alternative hypothesis:
The ratio of the number of cups of strawberry juice to the number of cups of lemon-lime soda is 7 : 1 ⇒ 3rd answer
Step-by-step explanation:
In A graph:
- Points are shown on ordered pairs (0 , 0) , (1 , 7) , (2 , 14) , (3 , 21) and (4 , 28) are connected by a line
- The label on the x-axis is Lemon-Lime Soda in cups
- The label on the y-axis is Strawberry Juice in cups
We need to find the ratio of the number of cups of strawberry juice to the number of cups of lemon-lime soda
∵ The points are connected by line
∵ The x-axis represents the number of cups of Lemon-Lime Soda
∵ The y-axis represents the number of cups of Strawberry Juice
∴ The ratio of the the number of cups of strawberry juice to the
number of cups of lemon-lime soda equal to the slope of the line
∵ The slope of the line
- You can calculate the slope of a line from any two points lie on it
∵ Points (1 , 7) and (2 , 14) lie on the line
∵ = 1 and
= 2
∵ = 7 and
= 14
∴
∵ The ratio of the number of cups of strawberry juice to the number
of cups of lemon-lime soda = m
∴ The ratio of the number of cups of strawberry juice to the number
of cups of lemon-lime soda = 7 : 1
The ratio of the number of cups of strawberry juice to the number of cups of lemon-lime soda is 7 : 1
