4.0 in. 6.0 in. 4. On the floor plan shown at the right, 1.25 inches represents 2 feet. What is the actual length of the entire floor? a. Kitchen 4.0 in. 6.0 in. Dining Room b. What is the actual area of the entire floor? Explain how you found the area. length 4.0 in. Study Living Room 8.0 in. 2.0 in. Foyer width
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
Where would

be if it was reflected across the x-axis
Answer:
(-3,-2)
Step-by-step explanation:
When you reflect over the x-axis, the x remains the same but the y changes to the opposite. In this case negative. I hope this helps, have a great day!
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 :)

A high school athlete has been offered football and track and field scholarships to multiple universities. For football, he has 3 offers in Alabama, 3 in North Carolina, and 2 in Florida. For track and field, he has 4 offers in Florida, 5 in Texas, and 4 in California.
The probability that he chooses to play football in North Carolina is?
Total Offers:
3 + 3 + 2 + 4 + 5 + 4 = 21
Offers for football in NC = 3

A manufacturer makes ball bearings that have a target diameter of 5 mm. Quality control engineers sample ball bearings from a batch to test the hypotheses H 0 : mu=5 mm vs. H a : mu ne5 mi , where u is the true mean diameter of the ball bearings in that batch. Suppose that H 0 is actually true. Which situation below would have the lowest probability of a Type I error?
Answer: n=30 the other one is 0.01 !
Step-by-step explanation:
khan
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).

13. Whats the domain and range?
14. What’s the domain and range?
Answer:
See below
Step-by-step explanation:
13) Domain: x -> {-3,-2,-1,0,1,2}, Range: f(x) -> {5}
14) Notice how x can't be -4 as that will make the denominator 0. Therefore, your domain is (-∞,-4)U(-4,∞) and your range is [0,∞) since 0 is the lowest possible real y-value that satisfies the equation (recall that if y<0, you are unable to find the real square root of a real number)
