Answer:
Solution = Infinitely many
Step-by-step explanation:
y = -x + 1
y - 1 = -x
y = -x + 1
y = -x + 1 (Multiply by -1)
y = -x + 1
-y = x - 1
0 = 0
Since 0 = 0 is true, this is an identity solution that has an infinite set of solutions

P(fewer than 7 boxes) -

Answer:
[tex]P(x < 7) = 0.383[/tex]
Step-by-step explanation:
Given
See attachment for plot
Required
Determine the probability that few than 7 boxes will be needed.
This is represented as:
[tex]P(x < 7)[/tex]
And the solution is:
[tex]P(x < 7) = P(x = 4) + P(x = 5) + P(x = 6)[/tex]
Each probability is calculated by dividing the number of dots by the total dots.
So, we have:
[tex]P(x < 7) = \frac{n(x = 4) + n(x = 5) + n(x = 6)}{Total}[/tex]
From the attached, the formula becomes:
[tex]P(x < 7) = \frac{4 + 6 + 3}{4+6+3+4+4+6+3+2+1+2+0+1}[/tex]
[tex]P(x < 7) = \frac{13}{36}[/tex]
[tex]P(x < 7) = 0.361[/tex]

Answer:
5 kilometers
Step-by-step explanation:
Just use distance formula for each island to his boat
The distance between is the number of units between them, and the distance from Diego's ship to the closest island is 5.4 units
What is a point coordinate?A point coordinate is the location of a point on the coordinate plane
From the question, the coordinate of point X is:
X = (-2, -4)
The closest island to point X is the island B, and the coordinate is:
B = (3, -6)
The distance is then calculated using:
XB =√[(x₁ - x₂)² + (y₁ - y₂)²]
So, we have:
XB =√[(-2 - 3)² + (-4 + 6)²]
Evaluate
XB = 5.4
Hence, the distance from Diego's ship to the closest island is 5.4 units

Step-by-step explanation:
Given:
Co-ordinate of points
m(-10, 3)
p(-4, -8)
Find:
Distance between points m and p
Computation:
Distance between two points = √(x1 - x2)² + (y1 - y2)²
Distance between points m and p = √(-10 + 4)² + (3 + 8)²
Distance between points m and p = √(-6)² + (11)²
Distance between points m and p = √36 + 121
Distance between points m and p = √157
Distance between points m and p = 12.53 unit (Approx.)

4. 29
Step-by-step explanation:
Since your trying to find the hypotenuse you equation is...
1. 28^2 + 45^2 = C^2
784 + 2025 = C^2
Square Root 2809= C^2
C=53
So after you square root 2809 you get 53.
2. 12^2 + 16^2 = C^2
144 + 256 = C^2
Square Root 400 = C^2
C=20
So after you square root 400 you get 40.
3. 12^2 + 35^2 = C^2
144 + 1225 = C^2
Square Root 1369 = C^2
C=37
So after you square root 1359 you get 37.
4. 20^2 + 21^2 = C^2
400 + 441 = C^2
Square root 841 = C^2
C=20
So after you square root 841 you get 29.

Answer:
Step-by-step explanation:
(-1,4) (1,4) 2,0
The endpoint of the line segment will be (-1, 4) and (2, 0). Then the correct options are B and E.
What is dilation?Dilation is the process of increasing the size of an item without affecting its form. Depending on the scale factor, the object's size can be raised or lowered. There is no effect of dilation on the angle.
A line segment in mathematics has two different points on it that define its boundaries. A line segment is sometimes referred to as a section of a path that joins two places.
Section Stomach muscle has endpoints A(- 2, 8) and B(4,0). The section is widened at the beginning by a scale variable of 0.5 to make a fragment of the Stomach muscle.
The endpoint of the line segment is given as,
A = 0.5(-2, 8)
A = (-1, 4)
B = 0.5(4, 0)
B = (2, 0)
The endpoint of the line fragment will be (- 1, 4) and (2, 0). Then the right choices are B and E.

x = 23 degrees
Step-by-step explanation:
It is given that the two parallel lines, (m) and (n) are intersected by a transversal. The two given angles (5x - 20) and (85) are alternate corresponding. Meaning that they are supplementary; their angle measures add up to (180) degrees. Based on this given information, form an equation and solve for the parameter (x).
(5x - 20) + (85) = 180
