Answer:
x = 36
Step-by-step explanation:
Answer:
The p value for this case is given by this probability:
Since the p value is lower than the significance level we have enough evidence to reject the null hypothesis and we can conclude that the true proportion of people who favored te construction is significantly higher than 0.78 or 78%
Step-by-step explanation:
Information given
n=900 represent the random sample taken
estimated proportion of residents who favored the construction
is the value to test
represent the significance level
z would represent the statistic
represent the p value
Hypothesis to test
We want to test if the true proportion is more than 0.78 or not.:
Null hypothesis:
Alternative hypothesis:
The statistic is given by:
(1)
Replacing the info we got:
The p value for this case is given by this probability:
Since the p value is lower than the significance level we have enough evidence to reject the null hypothesis and we can conclude that the true proportion of people who favored te construction is significantly higher than 0.78 or 78%
Answer:
35,000
Step-by-step explanation:
1. Find the difference between 75 and -51.
75 - (-51) = 75+51 = 126
2. Divide 126 by 3.6
126/3.6 = 35
3. Now what is the number 35? That is how much times the airplane has approached 1,000ft. So you have to multiply 35 and 1,000.
35 x 1,000 = 35,000.
4. Find the equation
([75 - x]/3.6) × 1,000, in which this case, x is the Fahrenheit the surroundings is in
a. Substitute x with -51.
b. The equation should follow the exact steps I mentioned earlier.
Hope this helps
Answer:
60
Step-by-step explanation:
The sum of two interior angles in a triangles is equal to one exterior angle that is supplementary to the third interior angle
3x+4x = 10x - 45
7x = 10x - 45 transfer 45 to the other side of equation and subtract 7x from 10 10
45 = 10x - 7x
45 = 3x divide both sides by 3
15 = x angle B is 4*15 = 60
Answer:
n+1=x-1
Step-by-step explanation:
as n goes up, x decreases by 1 each time
