Answer:
The slope of these coordinates is 0.
It is a horizontal line.
Step-by-step explanation:
a 56-inch board is to be cut into three pieces so that the second piece is three times as long as the first piece and the third piece is four times as long as the first piece if x represents the length of the first piece find the length of all three pieces
Step-by-step explanation:
length of 1st piece = x inch
length of 2nd piece = 3x inch
length of 3rd piece = 4x inch
x + 3x + 4x = 56
8x = 56
x = 7
Thus,
length of 1st piece = 7 inch
length of 2nd piece = 3 × 7 = 21 inch
length of 3rd piece = 4 × 7 = 28 inch

Step-by-step explanation:
There are 56 sheep in a paddock. Each sheep is either black or white. There are 6 times as many white sheep than black sheep. How many black sheep are there?
Here we want to make a system of equations and solve it, in this way, we will see that there are 8 black sheep.
first, let's define the variables:
x = number of black sheep
y = number of white sheep.
We know that:
"there are 56 sheep"
Then we can write:
[tex]x + y = 56[/tex]
We also know that there are 6 times as many white sheep than black sheep, this means that:
[tex]y = 6 \cdot x[/tex]
Then we have a system of equations:
[tex]x + y = 56[/tex]
[tex]y = 6\cdot x[/tex]
To solve this we need to start by isolating one of the variables in one of the equations. Here, we can see that the variable y is already isolated in the second equation, so we can use that.
Now we can replace that variable in the other equation:
[tex]x + y = 56[/tex]
[tex]x + 6\cdot x = 56[/tex]
Now we can solve this for x, the number of black sheep:
[tex]7\cdot x = 56\\\\x = 56/7 = 8[/tex]
There are 8 black sheep.

First Bank of Springdale operates a one-lane drive-in ATM machine. Cars arrive according to a Poisson distribution at the rate of 12 cars per hour. The time per car needed to complete the ATM transaction is exponential with mean 6 minutes. The lane can accommodate a total of 10 cars. Once the lane is full, other arriving cars seek service in another branch. Determine the following:(a) The probability that an arriving car will not be able to use the ATM machine because the lane is full.(b) The probability that a car will not be able to use the ATM machine immediately on arrival.(c) The average number of cars in the lane.
Answer:
a) 0.19
b) 0.9689
c) ≈ 6 cars
Step-by-step explanation:
Rate at which cars arrive = 12 cars/hour = 1/5 cars/minute
time needed by each car to complete ATM transaction = 6 minutes = 1/6 car/minute
capacity of lane = 10 car
n = 10
a) Calculate the probability of an arriving not using the ATM because the line is full
p ( not using the ATM ) = 0.19
b) probability that a car will not be able to use the ATM machine immediately on arrival
P ( n > 0 ) = 1 - Po
= 1 - 0.0311 = 0.9689
c) Average number of cars in the lane
Lq = 5.74 ≈ 6 cars

The figure consists of parallel lines and transversal. Find the value of x and y.
Will give BRAINLIEST!!!!
Answer:
x = 28 y = 122
Step-by-step explanation:
Transversal Lines would be 112 and 4x
112 / 4 = 28
x = 28
y and 122 are alternate interior angles
so y = 122

Can someone help? I hate math so much lol I don’t understand
Answer:
±6
Step-by-step explanation:
Given the mathematical expression;
√36 < √42 < √49
But, √36 = 6 * 6 = 6²
√49 = 7 * 7 = 7²
Simplifying further, we would substitute the new values respectively;
±[6] < √42 < ±[7]
Therefore, evaluating √36 is equal to ±6.

On a standardized exam, the scores are normally distributed with a mean of 300 and
a standard deviation of 40. Find the Z-score of a person who scored 240 on the exam.
Answer:
-1.5
Step-by-step explanation:
The Z - score of a person who scored 240 on the exam will be - 1.5.
What is Standard deviation?
Standard deviation is the measure of dispersed the data is in relation to the mean. Low standard deviation means data are clustered around the mean, and high standard deviation indicates data are more spread out.
Given that;
On a standardized exam,
The mean of scores = 300
Standard deviation = 40
Score on the exam = 240
Now,
Since, The Z - score is defined as;
Z - score = (X - μ) / σ
Where, μ is mean of scores and σ is Standard deviation.
Substitute all the values , we get;
Z - score = (X - μ) / σ
Z - score = (240 - 300) / 40
Z - score = - 60 / 40
Z - score = - 1.5
Therefore,
The Z - score of a person who scored 240 on the exam will be - 1.5.
