The greatest common factor being 12, the difference between the two values is 12.
What is GCD?
The greatest common divisor (GCD) from mathematics is the largest positive integer that splits each of two or more non-zero integers.
The symbol gcd stands for the greatest common divisor of the two integers x and y.
For instance, gcd(8,12)=4 is the GCD of the numbers 8 and 12.
According to the given question:
The greatest common factor of 48 and z, some unknown positive integer, is 12. There are two possible values for z between 10 and 30.
Now there are only two numbers between 10 and 30 which has a factor of 12.
The numbers are 12 and 24.
Hence the difference between these two numbers is 24 - 12 = 12
Therefore the required value is 12.

what is the probability of rolling a die ten times and obtaining odd digits on eight or less of the rolls?
The probability of rolling a die 10 times and obtaining odd digit 8 or less of the rolls is 529/512 = 1.033
Let us call, getting an odd no. on a roll of die, Success.
The, clearly, the probability p of Success is 3/6 = 1/2.
Hence, q = 1 −p = 1/2
If, X = x denotes the no. of success in n trials, then, X is a
Binomial Random Variable, with parameters
n = 10, and, p = 1/2.
Binomial Random Variable:
This is a specific type of discrete random variable. A binomial random variable counts how often a particular event occurs in a fixed number of tries or trials. For a variable to be a binomial random variable, ALL of the following conditions must be met:
There are a fixed number of trials (a fixed sample size).On each trial, the event of interest either occurs or does not.The probability of occurrence (or not) is the same on each trial.Trials are independent of one another.Then, the Probability of x success out of n trials, i.e.,
P (X = x), is,
P (X = x) = p(x) =ⁿCₓ pˣ , qⁿ⁻ˣ, x = 0,1,2, ........, n
In our case,
P (X = x) = ¹⁰Cₓ (1/2)ˣ (1/2)¹⁰⁻ˣ ,x = 0,1,2,..., 10, i.e.,
P (X = x) = p(x) = ¹⁰Cₓ (1/2)¹⁰ = ¹⁰Cₓ /1024, x = 0, 1, ..., 10.
Hence,
The Required Probability = P( X< 8),
⇒ P (X = 0)+ P( X = 1) + P(X = 2) + P(X = 3) + P(X = 4) + P(X = 5) +P(X = 6) + P(X= 7) + P(X =8)
⇒ 1/1024 ( 1 + 10 + 45 + 120 +210 + 252 + 210 + 120 +90)
⇒ 1/1024 ×1058
⇒ 529 / 512

There are two different ways in which he can choose 9 sandwitches. It can be solve by the concept of permutation and combination.
What is permutation and combination?
A permutation is an arrangement of several items taken one at a time or all at once in a specific order.
Combinations are based entirely on grouping. Combinations can be used to determine how many different groups that can be created from the available items.
Since all vegitarian sandwiches looks like same and all sandwitches with meat looks like same hence, their order will not affect the number of choice.
If 8 sandwitches are vegitarian then 1 sandwitch must be with meat. So that total sandwithches becomes 9.
If all 9 sindwitches are vegetarian then there is no option to choose another sandwitch. Because he can choose only 9 sandwitches.

You work for a real estate agency that sells and rents holiday homes in Data Islands. Recently, one of the interns working on the Data Science Team presents you a report. According to the linear regression model they have run, the price of a house is proportional to its age. But this does not make any sense: after all, newer houses should be worth more.
1. Comment the regression output, noticing that the Sig. column is reporting the p-value of the coefficient. What can you tell about the sign of Age’s slope?
2. Why do you think the model forecasts an higher price for old holiday homes? Think carefully about all the information you have concerning Data Island.
3. Assuming that more data and variables are available, what would you suggest your intern to do to fix their report?
A lovely beach resort is Data Island. Since it first became a popular tourist destination more than 80 years ago, the earliest vacation homes have been constructed just a few steps from the beach. You are a real estate agent for a company that deals in vacation rentals and sales in the Data Islands. A report was recently presented to you by one of the interns on the data science team. The age of a house affects its price, according to the linear regression model they have ran. But this is absurd because newer homes ought to be more valuable.
1. As the coefficient of Age is positive, so the older the house, the more price it is. Sig. (or p-value) = 0.000 which implies that the co-efficient of Age is significant.
2. This may be that the people who live there are reluctant to sell it, so they quote a higher price or the size of old houses are large or they may be located at prime location.
3. We would ask new interns to consider other independent variables for the regression equation like size of house, location, etc.

y = 5 - 1/3x + 7
y = 5 - 1/3(x) + 7
y = 5 - (1/3)x + 7
y = (5 - 1/3x) + 7
y = (5 + 7) - (1/3)x
y = 12 - (1/3)x

Therefore, when y = 12, x = 0.
dominic has a family history of hypertension. according to the chronic disease risk reduction intakes (cdrr) for sodium, dominic should lower or maintain his sodium intake to below mg/day to reduce his risk of chronic disease, including hypertension
Dominic should lower or maintain his sodium intake to below 2,300 mg/day.
Chronic disease :The Chronic Disease Risk Reduction (CDRR) consumption of 2,300 mg/day was recently developed due to connections between high sodium intake and the risk of hypertension. It is anticipated that sodium intake below this level will lower the risk of chronic diseases.
Adults may be at risk for chronic diseases if their sodium intake exceeds their CDRR intake. The population's cardiovascular health may be improved by efforts to reduce sodium consumption. Among healthy individuals, lowering daily sodium intake to CDRR is anticipated to lower the risk of developing chronic diseases, primarily by lowering blood pressure.
Hence, sodium intake to below 2,300 mg/day can reduce his risk of chronic disease.

I need help trying to find the area of this triangle please help.
Answer:
28 ft²
Step-by-step explanation:
You want the area of a triangle with a base of 7' and a height of 8'.
Area formulaThe formula for the area of a triangle is ...
A = 1/2bh
where b is the base of the triangle, and h is the height perpendicular to the base.
Here, it is convenient to use the side marked 7' as the base of the triangle. The distance marked 8' is the perpendicular distance from the base to the top of the triangle. So, the area is ...
A = 1/2(7 ft)(8 ft) = 28 ft²
The area of the triangle is 28 square feet.
__
Additional comment
As you can see, the vertex opposite the base does not need to lie above the base segment. All that matters is the perpendicular distance from that vertex to the base line.
