If the spinner shown is spun 40 times, predict the number of times the spinner would land on Section B.
Answers
Answer:
10 times
Step-by-step explanation:
Given that:
Number of sections = (A, B, C, D) = 4
Probability of spinner landing on section B on a single spin = required outcome / Total possible outcomes
P(landing on B) = 1 /4
Predicted Number of times spinner will land on D ; if spinner is spurned 40 times
1/4 * 40 = 10 times

Graph units are in kilometers. What is the distance from Diego's ship to the closest island? Round the final answer to the nearest tenth of a kilometer. Do not round intermediate calculations. \text{ km} km
Answers
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

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]

A spinner has an equal chance of landing on either red blue or green. You spin six times. What is the probability that spinner lands on red at least two times?
Answers
Answer:
0.8906 ( 4 decimal places)
Step-by-step explanation:
With an equal probability of landing in either blue or red, then
Probability of success, p = 0.5
Number of trials, n = 6
Probability of landing on red atleast twice Can be obtained using a cumulative binomial probability ;
P(x =x) = nCx * p^x * (1 - p)^(n - x)
P(x ≥ 2) = p(x = 2) + p(x = 3) + p(x = 4) + p(x = 5) + p(x = 6)
Obtaining the individual probabilities and summing them up or we could use a cumulative probability option on either a calculator, excel or an online binomial probability distribution.
Using an online binomial probability calculator :
P(x ≥ 2) = 0.890625
P(x ≥ 2) = 0.8906 ( 4 decimal places)

[please help, i would appreciate it alot]
Answers
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.
