Answer:
y=1/2x-5/2
Step-by-step explanation:
y-y1=m(x-x1)
y-(-3)=1/2(x-(-1))
y+3=1/2(x+1)
y=1/2x+1/2-3
y=1/2x+1/2-6/2
y=1/2x-5/2

The dot plots below show the number of points scored by Sam and Daniel in 15 basketball games.
Which statement is best supported by the data in the dot plots?
A The range for Daniel's data is greater than Sam's range.
B The median for Daniel's data is the same as the median for Sam's data.
C The range for Daniel's data is the same as the range for Sam's data.
D The median of Sam's data is greater than the median of Daniel's data.
Answer:
B.
Step-by-step explanation:
Sam median = 12 which has 3 points scored.
Daniel median = 16 which has 3 points scored.
Both scored the same amount of data which is 3 points.
Both the ranges are 16. so it cant be A or C.

You flip a coin 50 times. Of the 50 flips, the coin landed on heads 30 times. Use the questions below to compare the experimental probability of flipping heads with the theoretical probability of flipping heads.
Given:
Of the 50 flips, the coin landed on heads 30 times.
To find:
The experimental probability of flipping heads and compare it with the theoretical probability of flipping heads.
Solution:
We have,
Total number of trials = 50
Total number of heads = 30
The experimental probability of flipping heads is:
[tex]\text{Experimental probability}=\dfrac{\text{Total number of heads}}{\text{Total number of trials}}[/tex]
[tex]\text{Experimental probability}=\dfrac{30}{50}[/tex]
[tex]\text{Experimental probability}=\dfrac{3}{5}[/tex]
[tex]\text{Experimental probability}=0.6[/tex]
A coin has two sides one is heads and another is tails. So, the theoretical probability of flipping heads is:
[tex]\text{Theoretical probability}=\dfrac{1}{2}[/tex]
[tex]\text{Theoretical probability}=0.5[/tex]
Therefore, the experimental probability of flipping heads is 0.6 and the theoretical probability of flipping heads is 0.5. So, the experimental probability is greater than the theoretical probability of flipping heads.

Which job here requires the least amount of training and education
A. Elementary Teacher
B. College professor
C. Cashier
D. Accountant
Answer:
Cashier
Step-by-step explanation:
An elementary school teacher has to go to college, a college professor has to have a college degree, and although accountants are always required to go to college most places hire accountants that have gone to school.
Answer:
C. Cashier
Step-by-step explanation:
Retail cashiers require no formal training.
To be an elementary teacher, you must have at least a Bachelor's degree.
To be a college professor, you must have at least a Master's degree.
To be an accountant, you must have at least a Bachelor's degree.
Abigail and Grace collected clovers. Abigail collected clovers with
4 leafs and Grace collected clovers with 5 leafs. They counted the
number of leafs in both collections and realized that it is the
same. What is the least number of leafs that each collection must
have?
Answer:
20
Step-by-step explanation:
To find the least number of leafs that each collection must have, we find the L.C.M of both numbers. So L.C.M of 4 and 5.
The prime factors of 4 = 2²
The prime factors of 5 = 5
So L.C.M of 4 and 5 = 2² × 5 = 20
So, the least number of leafs that each collection can have is 20 leafs.
Naina went on a trip. She covered a distance of 34 Kilometre 46 metre by car, 143 kilometre 92 metre by train, 5 kilometre 92 metre by bus, 2 kilometre 60 metre on bullocks and 1.3 kilometre on foot. How much distance did she cover.
Answer:
185590 m
or 185 km 590 meters
Step-by-step explanation:
to calculate total distance covered, convert km to meter and adding the numbers together
1km = 1000m
34 Kilometre 46 metre = (34 x 1000) + 46 = 34046m
143 kilometre 92 metre = ( 143 x 1000) + 92 = 143,092m
5 kilometre 92 metre = (5 x 1000) + 92 = 5092
2 kilometre 60 metre = (2 x 1000) + 60 = 2060
1.3 km = 1.3 x 1000 = 1300

Step-by-step explanation:
4) 35° and x° are vertical angles, so they are congruent to each other. Therefore, x°=35°. Since y°+y°+35°=180° since they are all supplementary to each other, then y°=72.5° when solved.
5) A is true. Think of two adjacent angles measured 60° and 30° that are next to each other. They add up to 90° as well.
B isn't true. Vertical angles are congruent to each other, not supplementary.
C isn't true. The statement contradicts itself. Complementary angles add up to 90° while supplementary angles add up to 180°

Scientists notice two asteroids moving directly toward each other. Right now, they are 20 million kilometers apart, but they are on a collision course. The graph represents their paths and likely collision point, with the origin representing the initial position of asteroid A.
What is the point of intersection of the two lines, and what do the x- and y-values of the point of intersection mean?
Answer:
The point of intersection is (6, 8). This indicates that in 6 days, asteroid A and B will collide at a point that is 8 million miles away from asteroid A's current position and 12 million miles away from asteroid B's current position.

B)The perimeter of the rectangular bases changes by a factor of 2.
E)The area of the rectangular bases changes by a factor of 4.
Step-by-step explanation:
The right rectangular prisms are similar.
Which statements are correct? Check all that apply.
A)The angles in the smaller prism measure 90 degrees.
B)The perimeter of the rectangular bases changes by a factor of 2.
C)The surface area changes by a factor of 8.
D)The larger prism has twice the volume of the smaller prism.
E)The area of the rectangular bases changes by a factor of 4.
Solution:
Two polygons are said to be similar if they have the same shape, the ratio of their sides are in the same proportion and they have the same size of angles.
A) Since the bigger prism has angles with measure of 90°, hence the angles in the smaller prism will also measure 90.
Option A is correct.
B) Perimeter of bigger prism base = 2(2.2 + 0.8) = 6
Perimeter of smaller prism base = 2(1.1 + 0.4) = 3
The perimeter of the rectangular bases changes by a factor of 2 (6 / 3).
Option B is correct.
C) Surface area of bigger prism = 2(3.2*0.8 + 2.2*0.8 + 3.2*2.2) = 22.72
Surface area of smaller prism = 2(1.6*0.4 + 1.1*0.4 + 1.6*1.1) = 5.68
The surface area does not change by a factor of 8 (22.72 / 5.68 ≠ 8)
Option C is wrong
D) Volume of bigger prism = 2.2 * 3.2 * 0.8 = 5.632
Volume of smaller prism = 1.1 * 1.6 * 0.4 = 0.704
The larger prism volume is not twice of the smaller prism
Option D is wrong
E) Area of bigger prism base = 2.2*0.8 = 1.76
Area of smaller prism base = 2.2*0.8 = 0.44
The area of the rectangular bases changes by a factor of 4 (1.76 / 0.44 = 4)

MARKING BRAINLIEST IF U HELP 19 - s = 13; s = -6 yes no question
Answer:
Step-by-step explanation:
We have the equation 19 - s = 13, and are asked to determine whether s = -6 fits in.
To solve, we need to isolate "s", do as followed and subtract 19 from both sides :
s = -6
Since this is equal to what the question is asking, yes s = -6 is correct.

The measure of the unknown angle is 70 degrees
In circle geometry, there is a theorem that states that the angle at the centre of a circle is twice the angle at the circumference
Given the following parameters;
Angle at the circumference = x
Angle at the centre = 140 degrees
Using the given theorem;
140 = 2x
Swap
2x = 140
x = 140/2
x = 70
Hence the measure of the unknown angle is 70 degrees

what is the area of the white box
Answer:
12 m²Step-by-step explanation:
The white box is a rectangle with width of:
a = 2 m
and length of:
b = 7 m - 1 m = 6 m
So its area is A = 2 m × 6 m = 12 m²
{The shaded blue area is: (5 m + 1 m)(8 m) - 12 m² = 48 m² - 12 m² = 36 m²}
