Answer:
The middle term would be 48x
Step-by-step explanation:
In order to find this, we need to take the squares of the end terms and put them in a perfect square. Then we can distribute to find the middle term.
(3x + 8)^2
(3x + 8)(3x + 8)
9x^2 + 24x + 24x + 64
9x^2 + 48x + 64

Answer:
4x +5 = 17
Step-by-step explanation:
put the value 3 in plave of x
(4 x 3) + 5 =
12 + 5 = 17
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%
What is being asked here is to convert the value above from units of yards per second into miles per hour. To do this, we need a conversion factor to multiply to the value for it to be converted to another units. We do as follows:
Conversion Factors
1 mile = 1760 yards
1 hr = 3600 s
<span>3 yd/s ( 1 mile / 1760 yards ) (3600 s / 1 hr) = 10.8 miles per hour</span>
