Answer:
x = -5
Step-by-step explanation:
Multiply each x and 3 by -4, obtaining
-4x - 12 = 8
Now solve for x by combining the constants:
-4x = 20, or
x = -5
Answer: x=-5
Step-by-step explanation: distribute the -4 first to both x and 3
-4x-12 = 8 then add 12 to both sides to isolate x
-4x= 20
divide by -4 and you get x= -5
check it
-4(-5+3)
-4(-5)= 20 (a negative times a negative makes a positive)
then -4(3)= -12
20-12= 8
it checks out, hope this helps ^_^

A plane flying from City A to City B travels x miles per hour for a total
of 4.5 hours. The plane takes the same route on the return trip, traveling
25 miles per hour faster for a total of 4.25 hours. What is the total distance
that the plane travels?
Answer:
Step-by-step explanation:
Olivia, use the dirt formula d = rt
distance = rate * time
x = rate * 4.5
x = (rate+25) *4.25
set them equal
rate)*4.5 = (rate+25) *4.25
4.5rate = 4.25 rate + 106.25
4.5rate- 4.25 rate = 106.25
0.25rate = 106.25
rate = 425
4.5(425) = 1912.5
check it
4.25(425+25) = 1912.5 yes it checks , that's right :)

The situation that would have the lowest probability of a Type I error is the one with the smallest significance level (α).
What is hypothesis testing?Hypothesis testing is a statistical method that is used to make decisions about a population based on a sample of data.
It involves testing a null hypothesis (H0) against an alternative hypothesis (Ha) using statistical techniques.
We have,
In hypothesis testing,
A Type I error occurs when we reject the null hypothesis (H0) when it is actually true.
The probability of a Type I error is denoted by the symbol alpha (α) and is usually set to a small value, such as 0.05 or 0.01.
Now,
To minimize the probability of a Type I error, we want to choose a significance level (α) that is small.
This means that we are willing to accept a lower probability of detecting a difference when one actually exists (i.e., a higher probability of a Type II error).
For example,
If we set α = 0.01, we are saying that we are willing to accept only a 1% chance of incorrectly rejecting the null hypothesis (H0) when it is actually true. This would result in a very small probability of a Type I error.
Therefore,
The situation that would have the lowest probability of a Type I error is the one with the smallest significance level (α).

Answer:
Part A= 19.2 Part B= 27.2
Step-by-step explanation:
4+8=12 divided by 1.25 equals 19.2
Width= 4+6=10 divided by 1.25=8
19.2+8= 27.2 is the total area
Hope this is right (:
Answer:
A. 19.2 Feet
B. 307.2 Feet
Step-by-step explanation:
A. First you divide 2 feet by 1.25 inches to figure out how much feet per inch.
2/1.25=1.6 feet
Meaning that 1 inch is 1.6 feet or 1 inch=1.6 feet
After that you add the length of 4 inches and 8 inches which equals 12 inches.
4+8=12 inches
After that you multiply 12 by 1.6
12*1.6=19.2
Meaning that the actual length is 19.2 feet
B. Once you find the length you add 4 inches and 6 inches which equals 10 inches.
Multiply 10 by 1.6
10*1.6=16 feet
After that to find the area you multiply 16 and 19.2.
16*19.2=307.2 feet
