The distance between P and T on the coordinate grid is ___ units. (Input whole numbers only.) Image of a coordinate grid with point P located at negative 10, 15 and point T located at 15, 15.
Answer:
The distance between P and T on the coordinate grid is 25 units.
Step-by-step explanation:
Coordinate of P = (-10,15)
Coordinate of T = (15,15)
By distance formula we have distance between ( a,b) and (c,d) is
[tex]\sqrt{(c-a)^2)+(d-b)^2}[/tex]
Here (a,b) = Coordinate of P = (-10,15) and (c,d) = Coordinate of T = (15,15)
Substituting
[tex]\texttt{Distance =}\sqrt{(c-a)^2)+(d-b)^2}=\sqrt{(15-(-10)^2)+(15-15)^2}=\sqrt{25^2}=25units[/tex]
The distance between P and T on the coordinate grid is 25 units.

What is the difference between a buffalo and a birthday cake?
Answer:
The buffalo is an animal and the birthday cake is a food.
Step-by-step explanation:
Hi, Buffaloes are heavily built oxen, with sparsely haired skin, large ears, long, tufted tails, broad muzzles and massive angulated horns. In having only 13 pairs of ribs they resemble the typical oxen. African buffaloes all have the hair of the back directed backwards.
A birthday cake is like a normal cake but made for the special celebration of birthdays.
Which normal distribution has a wider spread: the one with mean 3 and standard deviation 4 or the one with mean 4 and standard deviation 3 ? the normal distribution with mean 4 and standard deviation 3 has the wider spread?
Answer:
The correct option is 1. The normal distribution with mean 3 and standard deviation 4 has a wider spread.
Step-by-step explanation:
Normal distribution is defined by two variables, mean and standard deviation.
[tex]Z=\frac{X-\mu}{\sigma}[/tex]
The spread of a normal distribution is not dependent on mean, it is completely dependent of standard deviation. Larger standard deviation means wider spread.
It is given that first normal distribution has
[tex]\mu_1=3[/tex]
[tex]\sigma_1=4[/tex]
Second normal distribution has
[tex]\mu_2=4[/tex]
[tex]\sigma_2=3[/tex]
Since [tex]\sigma_1>\sigma_2[/tex], therefore the normal distribution with mean 3 and standard deviation 4 has a wider spread.
Hence the correct option is 1.
Final answer:
The normal distribution with a mean of 3 and a standard deviation of 4 has a wider spread than a normal distribution with a mean of 4 and a standard deviation of 3, as the spread is determined by the standard deviation.
Explanation:
The question is asking which of the two normal distributions has a wider spread. The spread of a normal distribution is determined by its standard deviation. A normal distribution with a higher standard deviation will have a wider spread. In this case, the normal distribution with a mean of 3 and a standard deviation of 4 will have a wider spread compared to the normal distribution with a mean of 4 and a standard deviation of 3. Thus, the statement 'the normal distribution with mean 4 and standard deviation 3 has the wider spread' is incorrect.
In a normal distribution, as the standard deviation increases, the distribution curves become wider and shorter, reflecting a greater spread in the data. Because both distributions are normally distributed, we can compare the standard deviations directly to determine the spread: a standard deviation of 4 indicates a wider spread than a standard deviation of 3.
A store is having a sale on almonds and jelly beans. For 8 pounds of almonds and 3 pounds of jelly beans, the total cost is $18 . For 2 pounds of almonds and 5 pounds of jelly beans, the total cost is $13 . Find the cost for each pound of almonds and each pound of jelly beans.
By setting up a system of equations and solving them, we find that the cost per pound of almonds is $1.50, and the cost per pound of jelly beans is $2.00.
To find the cost for each pound of almonds and each pound of jelly beans, we can set up two equations to solve the problem algebraically. Let's denote the cost per pound of almonds as a and the cost per pound of jelly beans as b. We have two scenarios provided:
8 pounds of almonds and 3 pounds of jelly beans cost a total of $18.
2 pounds of almonds and 5 pounds of jelly beans cost a total of $13.
We can translate these scenarios into two algebraic equations:
8a + 3b = 18
2a + 5b = 13
Now, we will solve this system of equations to find the values of a and b.
Step 1: Multiply Equation (2) by 4
8a + 20b = 52 (We multiplied all terms by 4 to match the coefficient of a in Equation (1))
Step 2: Subtract Equation (1) from the new equation
8a + 20b - (8a + 3b) = 52 - 18
17b = 34
Step 3: Solve for b
b = 34 / 17
b = 2
Now we know each pound of jelly beans costs $2.
Step 4: Substitute b back into Equation (1) to solve for a
8a + 3(2) = 18
8a + 6 = 18
8a = 12
a = 12 / 8
a = 1.5
So, each pound of almonds costs $1.50.
Therefore, the cost per pound of almonds is $1.50, and the cost per pound of jelly beans is $2.00.

construct a recursive rule to describe the sequence: 2, 4, 6, 8,...
Answer:
a[1] = 2; a[n] = a[n-1] + 2
Step-by-step explanation:
The first term of the sequence is 2, so the first part of the definition is ...
a[1] = 2
Each term is 2 more than the previous one, so the rest of the definition is ...
a[n] = a[n-1] + 2
_____
Comment on recursive rules
A recursive rule has two parts. The first part tells what the initial value of the sequence is. The second part relates the next term to the previous term or terms.
For arithmetic and geometric sequences, each term is related to the previous term by a constant. For an arithmetic sequence, each term is the last term plus the common difference. For a geometric sequence, each term is the last term multiplied by the common ratio.
For the arithmetic sequence 2, 4, 6, 8,.., the recursive rule can be written as: the first term a_1 is 2, and for all subsequent terms (n > 1), a_n equals the previous term a_(n-1) plus 2.
Explanation:The sequence given is an arithmetic sequence, where each term increases by 2. A recursive sequence is a sequence in which each term is defined based on its preceding terms. For the sequence 2, 4, 6, 8,... the recursive rule can be constructed as follows:
a_1 = 2
a_(n) = a_(n-1) + 2 for n > 1
In these rules, a_1 is the first term in the sequence, and a_(n) is the nth term of the sequence. a_(n-1) represents the term before the nth term in the sequence. This rule states that each term in the sequence is 2 more than the previous term.

If possible, use the Law of Detachment to draw a conclusion from the two given statements. If not possible, write not possible. Statement 1: If x = 7, then 7x – 2 = 47. Statement 2: x = 7
Answer:
x=7
Step-by-step explanation:
The Law of Detachment can be used to conclude that 7x - 2 = 47.
Explanation:The Law of Detachment states that if a conditional statement is true and its hypothesis is true, then its conclusion must also be true. In this case, Statement 1 is a conditional statement: 'If x = 7, then 7x - 2 = 47.' Statement 2 tells us that x = 7. Since the hypothesis of Statement 1 is true (x = 7), we can apply the Law of Detachment to conclude that its conclusion must also be true. Therefore, we can validate Statement 1: '7x - 2 = 47.'
