Find the slope of the line passing through the given points using the slope formula. Describe the slope as positive, negative, zero, or undefined.
(−5, −17) and (−5, −3)
Answer:
slope is undefined
Step-by-step explanation:
Calculate the slope m using the slope formula
m = \(\frac{y_{2}-y_{1} }{x_{2}-x_{1} }\)
with (x₁, y₁ ) = (- 5, - 17) and (x₂, y₂ ) = (- 5, - 3)
m = \(\frac{-3+17}{-5+5}\) = \(\frac{14}{0}\)
Since division by zero is undefined, then
the slope of the line is undefined
When the interval [3, 11] is divided into 16 subintervals of equal length, each of the subintervals has length (a) 2. (b)4. (b) 4. () Select one: o a. 2 ob.4 O c. 1/2
When the interval [3, 11] is divided into 16 subintervals of equal length, each of the subintervals has length (a) 2. (b)4. (b) 4. () c. 1/2
When the interval [3, 11] is divided into 16 subintervals of equal length, we can use the formula:
length of each subinterval = (length of the interval) / (number of subintervals)
Therefore, the length of each subinterval would be:
(11 - 3) / 16 = 8 / 16 = 1/2
So the answer is (c) 1/2.
This means that each of the 16 subintervals would have a length of 1/2. It's important to note that the number of subintervals does not affect the length of the interval itself, only the length of each subinterval.
It's also worth mentioning that if we had divided the interval [3, 11] into a different number of subintervals of equal length, the length of each subinterval would have been different. This formula is specific to dividing an interval into a certain number of subintervals.

Answer:
The answer would be 6.
Step-by-step explanation:
First, we need to make equations for these electricians fee's.
Electrician one: Y=25x+50, 50 is the upfront cost and 25 is the cost per hour for work.
Electrician two: Y=27.50x+35, It is the same thing for these numbers.
Then you need to incert numbers into the X place. Y will be your answer.
Y=25(6)+50, Y=150+50, Y=200
Y=27.50(6)=35, Y=165+35, Y=200
The answer would be 6. If both the electricians worked for 6 hours each, their prices would be equal.

The number of customers that arrive at a fast-food business during a one-hour period is known to be Poisson distributed with a mean equal to 8.60. What is the probability that exactly 8 customers will arrive in a one-hour period?
The probability that exactly 8 customers will arrive in a one-hour period is 0.1563, or approximately 15.63%. The probability of exactly 8 customers arriving in a one-hour period can be calculated using the Poisson distribution formula.
The formula is P(X=x) = (e^-λ * λ^x) / x!, where λ is the mean number of customers arriving in a one-hour period and x is the number of customers we want to calculate the probability for.
So in this case, λ = 8.60 and x = 8. Plugging these values into the formula, we get:
P(X=8) = (e^-8.60 * 8.60^8) / 8!
P(X=8) = 0.1563
Therefore, the probability that exactly 8 customers will arrive in a one-hour period is 0.1563, or approximately 15.63%.

A rainstorm in Portland. Oregon has wiped out the electricity in about p% of the households in the city. A management team in Portland has a big meeting tomorrow, and all 7 members of the team are hard at work in their separate households preparing their presentations. The probability that none of them has lost electricity in his/her household is 0.2097. Assume that the locations are spread out so that loss of electricity is independent among their households. Then p is equal to:
The probability that none of the 7 members of the team has lost electricity in their households is given as 0.2097. The value of p is 22%.
Let's solve for the value of p.
The probability that none of the 7 members of the team has lost electricity in their households is given as 0.2097. We can use this information to find the value of p.
Since the loss of electricity in each household is independent, the probability of none of the 7 households losing electricity is the product of the individual probabilities:
P(none of them has lost electricity) = (1 - p/100)^7
Given that this probability is equal to 0.2097, we can set up the equation:
(1 - p/100)^7 = 0.2097
Taking the 7th root of both sides, we get:
1 - p/100 = (0.2097)^(1/7)
Simplifying further:
1 - p/100 = 0.7777
Now, solving for p:
p/100 = 1 - 0.7777
p/100 = 0.2223
p ≈ 22.23%
Rounding to the nearest whole percentage, p is approximately 22%.
Therefore, the value of p is 22%.

The marching band walks 1/15 miles in 1.5 minutes. At this rate, how many minutes will it take to complete 1 mile? Record your answer on the grid. Then fill in the bubbles
Answer:
It will take 22.5 minutes to complete 1 mile
Step-by-step explanation:
From the question,
The marching band walks 1/15 miles in 1.5 minutes
First we will determine the miles cover in 1 minute
If the marching band walks 1/15 miles in 1.5 minutes
then, they will cover \(x\) miles in 1 minute
\(x = \frac{1/15 * 1}{1.5}\\\)
Then,
\(x = \frac{1/15 }{1.5}\)
\(x = 2/45\) miles
∴ 2/45 miles are covered in 1 minute
Now,
If 2/45 miles are covered in 1 minute
Then, 1 mile will be covered in \(y\) minute
\(y = \frac{1 * 1}{2/45}\)
\(y =\frac{1}{2/45} \\y = \frac{45}{2}\\\)
∴ \(y = 22.5 minutes\)
Hence, it will take 22.5 minutes to complete 1 mile

another thing is that slope in this equation is negative. This means the line is decreasing or going/pointing down. The only possible answer is a.
What are the Miller indices for the plane shown in the following cubic unit cell and Explain why? O (201) O (10 1/2) O (1 infinity 1/2) O (102)
The plane intercepts on the x,y, z axes are 1, ∞, and 1/2. Hence, the Miller indices for the plane inside the cubic unit cell is (102).
Miller indices are used to specify planes and directions. These planes and directions could be in lattices or crystals. The number of indices will correspond to the size of the lattice or crystal.
Steps to find the Miller indices:Determine intercepts of the planes with the x, y, and z axes.Use fractional coordinates to specify intercepts.Take the reciprocals of the fractional interceptsIn the given graph, the plane intercepts are:
x-intercept : 1
y-intercept : ∞ (since the planes does not intercept y-axes)
z-intercept = 1/2
Take the reciprocal:
1/1 = 1
