Answer:
X is the answer.
Step-by-step explanation:
Find p(x = 4) if x has a poisson distribution such that 3p(x = 1) = p(x = 2).
The formula for Poisson distribution is:
P (x) = e^-k * k^x / x!
We know that:
3P(x = 1) = P(x = 2)
Therefore:
3 [e^-k * k^1 / 1!] = e^-k * k^2 / 2!
Simplifying by cancelling similar terms:
3 / 1! = k / 2!
k = 3 * 2! / 1!
k = 6
So at x = 4:
P (x = 4) = e^-6 * 6^4 / 4!
P (x = 4) = 0.1339 or 13.39%

What is the slope of the line passing through the points (1, −5) and (4, 1)? −45 54 2 −2
Answer:
Slope of the line passing through the points (1, −5) and (4, 1) is 2 .
Step-by-step explanation:
The equation of the slope is given by
[tex]m = \frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]
As given
line passing through the points (1, −5) and (4, 1) .
[tex]m = \frac{1-(-5)}{4-1}[/tex]
[tex]m = \frac{1+5}{4-1}[/tex]
[tex]m = \frac{6}{3}[/tex]
m = 2
Therefore the slope of the line passing through the points (1, −5) and (4, 1) is 2 .

∆ABC and ∆FDE are congruent by the
criterion. (Use the three-letter abbreviation without spaces.)
The value of x is
, and the value of y is
.
The values of x and y are 4.29 and 90.
Given that ∆ABC and ∆FDE are congruent by a certain criterion, let's denote the corresponding sides as follows:
AB = FD (corresponding side)
BC = DE (corresponding side)
AC = FE (corresponding side)
Let's also denote the angles of ∆ABC and ∆FDE as follows:
∠A = ∠F (corresponding angle)
∠B = ∠D (corresponding angle)
∠C = ∠E (corresponding angle)
Now, if we're given specific values for some sides or angles, we can use that information to find the missing values.
Let's assume we're given that AB = 5 cm, BC = 7 cm, AC = 6 cm, ∠A = 40°, and ∠B = 50°.
First, let's find the missing side FD using the side-length proportion:
[tex]\[ \frac{AB}{FD} = \frac{BC}{DE} = \frac{AC}{FE} \][/tex]
Substitute the given values:
[tex]\[ \frac{5}{FD} = \frac{7}{DE} = \frac{6}{FE} \][/tex]
We can solve for FD by setting up the proportion:
[tex]\[ \frac{5}{FD} = \frac{7}{6} \][/tex]
Cross-multiply to solve for FD:
[tex]\[ 5 \cdot 6 = FD \cdot 7 \][/tex]
[tex]\[ 30 = 7FD \][/tex]
[tex]\[ FD = \frac{30}{7} \][/tex]
[tex]\[ FD \approx 4.29 \text{ cm} \][/tex]
Next, we can find the missing angle measures. Since ∠A = ∠F = 40° and ∠B = ∠D = 50°, we can find ∠C = ∠E using the fact that the sum of angles in a triangle is 180°:
[tex]\[ ∠C = 180° - ∠A - ∠B \][/tex]
[tex]\[ ∠C = 180° - 40° - 50° \][/tex]
[tex]\[ ∠C = 90° \][/tex]
So, we have found that FD ≈ 4.29 cm and ∠C = 90°. Thus, the values of x and y are 4.29 and 90, respectively.

3ax + 2b / c = 4d solve for x
Final answer:
To solve the equation 3ax + 2b / c = 4d for x, isolate x on one side of the equation by multiplying both sides by c, subtracting 2b, and dividing by 3a.
Explanation:
To solve the equation 3ax + 2b / c = 4d for x, we need to isolate x on one side of the equation. Here are the steps:
Multiply both sides of the equation by c to get rid of the denominator: 3ax + 2b = 4cd.Subtract 2b from both sides of the equation: 3ax = 4cd - 2b.Divide both sides of the equation by 3a to solve for x: x = (4cd - 2b) / (3a).Therefore, the solution for x is x = (4cd - 2b) / (3a).

How many square units are in an office that is 13 units by 9 units? 22 117 121 130?
By using the formula for the area of a rectangle, we will see that there are 117 square units on the office.
How many square units are in the office?We know that for a rectangle of width W and length L, the area is given by:
A = W*L
In this case, we have a rectangle of width of 13 units, and length of 9 units, replacing that in the area equation:
A = (13 units)*(9 units) = 117 square units.
So the correct option is the second one, there are 117 square units in the office.
