Answer:
The figure is reflected over y = -2
Step-by-step explanation:
If you draw a horizontal line through y = -2, so will see that every point is the same distance from y = -2 but in the opposite direction. For example, Point w is 3 units above y= -2 and w' is three units below y = -2. That is true for every point on original to the image.

the midpoint theorem :
the line segment in a triangle connecting the midpoints of two sides of the triangle is said to be parallel to its third side and is also half of the length of the third side.
therefore,
MN connects the midpoints of AC and AB, and is therefore half of BC.
PQ connects the midpoints of AN and AM, and is therefore half of MN. and that is half of half of BC = one quarter of BC.
MN = 1/2 × BC
PQ = 1/2 × MN = 1/2 × 1/2 × BC = 1/4 × BC =
= 1/4 × 16 = 4 mm
3.
UV = 10 cm connects the midpoints of PT and PS, and is therefore 1/2 of TS.
in other words, TS = 2×UV = 2×10 = 20 cm.
now we go the other direction from Q :
TS connects to midpoints of QU and QR. therefore,
UR = 2×TS = 2×20 = 40 cm.
VR = UR - UV = 40 - 10 = 30 cm
Select the action you would use to solve x-4=16 then select property that justifies the action
Answers
The value of x is 64 and the property that justifies that action is the multiplication property of equality.
What is an expression?
It is defined as the combination of constants and variables with mathematical operators.
Mathematical statements are called expressions if they contain at least two terms that are connected by an operator and contain either numbers, variables, or both. Addition, subtraction, multiplication, and division are all possible mathematical operations.
As an illustration, the expression x + y is one where x and y are terms with an addition operator in between. There are two types of expressions in mathematics: numerical expressions, which only contain numbers, and algebraic expressions, which also include variables.
We have an expression:
x/4 = 16
Apply Multiplication property of equality:
Multiply by 4 on both sides:
(x/4)4 = 16×4
x = 64
Thus, the value of x is 64 and the property that justifies that action is the multiplication property of equality option (1) is correct.

What are the coordinates of (-4,-2) rotating 90° counterclockwise?
Answers
Answer:
(2, -4)
Step-by-step explanation:
The rotation of an object turns the object around a fixed point called the center of rotation.
A rotation of 90° counterclockwise means:
A 90° rotation counterclockwise with the origin (0, 0) as the center of rotation.
The rule for a counterclockwise rotation of 90° about the origin is:

What proportion of people surveyed would be willing to pay more than $6.75 for a sandwich?
Answers
The proportion of people surveyed would be willing to pay more than $6.75 for a sandwich is 94.4%.
What is termed as normal distribution?The normal distribution, also recognized as the Gaussian distribution, is a symmetric probability distribution about the mean, indicating that data near the mean occur more frequently than data far from the mean.
Early statisticians started to notice the same shape recurring in different distributions and designated it the normal distribution. Normal distributions are distinguished by their symmetric bell shape. The mean and median are the same; they are both in the middle of the distribution.As, for the given value in the question;
The formula for finding the z-score is;
z = (x - μ)/s
where,
n = sample size ( = 528)
σ = standard deviation ( = 1.19)
μ = mean of the sample (= 6.56)
Put the values and fine z-score.
z = (x - μ)/s
z = (6.75 - 6.56)/1.19
z = 0.19/1.19
z = 0.159
For the probability; see the p-value from the positive z-score table.
p(z > 0.159) = 0.944
p(z > 0.159) = 94.4%
Thus, the probability that the people would be willing to pay more than $6.75 for a sandwich is calculated as 94.4%.

Ray BD bisects angle abc. Find the m angle abd m angle cbd and m abc
Answers
m∠ABD= 67°, m∠CBD= 67° and m∠ABC= 134°;
Bisector BD bisects ∠ABC.
∠ABD= (8x+35)°, ∠CBD= (11x+23)°.
As given, bisector BD bisects the angle ABC so this means, the angle ABC is divided into two halves.
So,
angle ABD= angle CBD.
and ∠ABD= (8x + 35)° (i)
∠CBD= (11x + 23)° (ii)
So,
(8x + 35)° = (11x + 23)°
On solving the above equation, we have
3x= 12
x= 4.
Putting x=4 in (i) we have,
∠ABD= 8(4) + 35
∠ABD= 67°
As ∠ABD = ∠CBD, we have
∠CBD= 67°
Now,
∠ABC= ∠ABD + ∠CBD
∠ABC= 67° + 67°
∠ABC= 134°.
Hence, m∠ABD= 67°, m∠CBD= 67° and m∠ABC= 134°.

Answers
The Shorter route as per the bearing calculations is taken up by Julia.
What is a bearing?
The angle from the north line, expressed in degrees, is the correct bearing to a given point. The real bearing will simply be referred to as the bearing.A point's bearing is the number of degrees inside the angle measured counterclockwise from the north line towards the line connecting the point and the compass's center.When describing the direction from one point in relation to another, a bearing is utilized.Bearing calculations are illustrated below:
Route Taken up by Anna
360-330= 30°
First angle =90-30= 60°
Second angle= 60+(90-40) =110°
Third angle= 180-(110+30)= 40°
Route taken up by Julia:
First angle =20°
Second angle= 300-(180+20)=100°
Third angle=180-(20+100)=60°

The average temperature in the mountains is 61° in April. The average temperature in that same spot is −2° in December. Determine how much warmer this location is in April than in December, and determine which temperature is the farthest away from 0°.
Answers
Answer: 59 degrees warmer and -2 is farther away form 0 than 61 degrees.
Step-by-step explanation: 59+2=61 so, that's how I got the answer. The rest is really easy.
The absolute value of 61°F is greater than the absolute value of 2°F. Therefore, the temperature of 61°F in April is the farthest away from 0°F.
To determine how much warmer the location is in April than in December, you can calculate the difference between the two temperatures:
Temperature difference = April temperature - December temperature
Temperature difference = 61°F - (-2°F)
Temperature difference = 61°F + 2°F
Temperature difference = 63°F
So, the location is 63 degrees Fahrenheit warmer in April than in December.
To determine which temperature is the farthest away from 0°F, you can calculate the absolute value of the difference between each temperature and 0°F and then compare them:
Absolute value of (61°F - 0°F) = 61°F
Absolute value of (-2°F - 0°F) = 2°F
The absolute value of 61°F is greater than the absolute value of 2°F. Therefore, the temperature of 61°F in April is the farthest away from 0°F.
