one possible combination of homeroom groups is 18 groups of 10 students and 5 groups of 12 students. which equation uses the x = 10 students and y=12 students, combination to represent the situation in point- slope form? is the answer y-18 =-5/6 (× - 5) ,y- 5 = - 5/6 (× -18) ,y +5 =-5/6 (× +18) or y+18= -5/6 (× +5)
Answers
Answer: y - 5 = -5/6 (x - 18)
Step-by-step explanation:
The point-slope form of a linear equation is written using the slope of the line and one point in the line. From part A, the slope of the line representing this situation is m = -5/6.
Since x represents the number of 10-student groups and y represents the number of 12-student groups, the combination of 18 groups of 10 students and 5 groups of 12 students is represented by the point (18,5).

$80,000, and if it is installed, no losses from this type of incident will be incurred. However, if the generator is not installed, there is a 12% chance that a power outage will occur during a year. If there is an outage, there is a .07 probability that the resulting losses will be very large, or approximately $7 million in net aggregated loss. Alternatively, it is estimated that there is a .93 probability of only slight losses of around $1 million. Using decision tree analysis, determine whether the SPEA should have install the new power generator. What considerations may change your decision?
Answers
Answer:
SPEA should have install the new power generator.
Step-by-step explanation:
The information provided is as follows:
The cost of the emergency generator is $80,000, and if it is installed (I), no losses from this type of incident will be incurred. If the generator is not installed (I'), there is a 12% chance that a power outage (P) will occur during a year. If there is a power outage, there is a 0.07 probability that the resulting losses will be very large (HL), or approximately $7 million in net aggregated loss. Alternatively, it is estimated that there is a 0.93 probability of only slight losses (SL) of around $1 million.Consider the decision tree attached below.
The loss that will be incurred after the generator is installed is, $80,000.
Compute the loss that will be incurred if the generator is not installed as follows:
[tex]E(\text{Loss})=P(HL|P)P(P)\times \$7000000+P(SL|P)P(P)\times \$1000000[/tex]
[tex]=(0.07\times 0.12\times \$7000000)+(0.93\times 0.12\times \$1000000)\\=58800+111600\\=170400[/tex]
The loss that will be incurred if the generator is not installed is $170,400.
The loss from not installing the generator is more than from installing it.
Thus, SPEA should have install the new power generator.
What are the values of x and y?
Answers
Answer:
For instance, the equation y = x expresses a relationship where every x value has the exact same y value. The equation y = 2x expresses a relationship in which every y value is double the x value, and y = x + 1 expresses a relationship in which every y value is 1 greater than the x value.

Recall the hurricane relief fund context from the previous investigation. Bob set up a hurricane relief donation fund and started it off by donating $ 35 . Instead of tripling in value each day, suppose it doubled in value each day
Complete the following table showing the account values at the end of each day.
Number of days since the initial investment, n Amount (in dollars) in the relief account, A
0 1 2 3 4
Answer:
Number of days(n) = Amount (in dollars) in the relief account(A)
0 = $35
1 = $70
2 = $140
3 = $280
4 = $560
Step-by-step explanation:
The formula for doubling time
P(t) = Po(2)^t/k
Where P = Amount after time t
Po = Initial Amount
t = number of days
k = Frequency at which it doubles
For 0 days
t = 0, k = 1, P(o) = $35
P(t) = Po(2)^t/k
P(0) = $35(2)^0/1
= $35(2)⁰
= $35 × 1
= $35
For 1 day
t = 1, k = 1 , P(0) = $35
P(t) = Po(2)^t/k
P(0) = $35(2)^1/1
= $35(2)¹
= $35 × 2
= $70
For 2 days
P(t) = Po(2)^t/k
t = 2, k = 1, P(0) = $35
P(0) = $35(2)^2/1
= $35(2)²
= $35 × 4
= $140
For 3 days
P(t) = Po(2)^t/k
t = 3, k = 1
P(0) = $35(2)^3/1
= $35(2)³
= $35 × 8
= $280
For 4 days
P(t) = Po(2)^t/k
t = 3, k = 1, P(0) = $35
P(0) = $35(2)^5/1
= $35(2)⁴
= $35 × 16
= $560
how many yards are 2 miles and 30 feet
Answers
Hey there!☺
[tex]Answer:\boxed{3,530}[/tex]
[tex]Explanation:[/tex]
2 miles = 3,520 yards
30 feet = 10 yards
Add up both.
[tex]3,520+10=3,530[/tex]
3,530 is your answer.
Hope this helps!☺
The number of yards for 2 miles and 30 feet by unit conversion is given by the relation A = 3530 yards
Given data ,
Let the total number of yards be represented as A
Now, the value of A is
The initial number of miles = 2 miles
where 1 mile = 1760 yards
So , 2 miles = 3520 yards
From the unit conversion , we get
30 feet = 10 yards
So , the total number of yards A = 3520 + 10
On simplifying the equation , we get
A = 3530 yards
Hence , the unit conversion is solved and total yards = 3530 yards

Answers
x≤ 16 is the solution of the given 17 + x≤ 33 inequality, Option D is correct.
What is Inequality?a relationship between two expressions or values that are not equal to each other is called 'inequality.
The given inequality is 17 + x≤ 33
We have to find the solution of the inequality seventeen plus x less than or equal to thirty three.
Now let us solve for x
Subtract seventeen from both sides to isolate the x variable.
17 + x - 17 ≤ 33 -17
In left hand side the seventeen will be cancelled and left with only variable x
x≤ 33 -17
When seventeen is subtracted from thirty three we get sixteen
x≤ 16 is the solution
Hence, x≤ 16 is the solution of the given 17 + x≤ 33 inequality, Option D is correct.

Solve for the value of X.
60°
8x - 4
Answers
Answer:
x = 8
Step-by-step explanation:
Asuming the equation is 8x-4=60°,
Simplifying
8x + -4 = 60
Reorder the terms:
-4 + 8x = 60
Solving
-4 + 8x = 60
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '4' to each side of the equation.
-4 + 4 + 8x = 60 + 4
Combine like terms: -4 + 4 = 0
0 + 8x = 60 + 4
8x = 60 + 4
Combine like terms: 60 + 4 = 64
8x = 64
Divide each side by '8'.
x = 8
Simplifying
x = 8
