The correlation coefficient is a number that indicates the direction
and closeness of points of a line of best of fit.
So it tells us two things.
It tells us the direction of the line of best fit
and it tells us the closeness of the points.
Usually, anything between -0.9 and -0.6 has a moderate negative correlation. If you look at this on a graph, you will notice that the points definitely resemble a line so we say it's moderate.
It will be a negative correlation because the slope is negative.

Based on the dimensions in the diagram, what is the value of x?
The value of ∠x is 30⁰. Option B is correct.
How to determine the ratio value of ∠x in the figure.
From the given figure,
The triangle formed by ladder is right angled triangle
∠x⁰ is opposite to the horizontal distance between the foot of the and the point where the ladder touches the ground.
The ladder form the hypotenuse of the triangle.
Therefore,
sinθ = opposite/hypotenuse
θ is the angle opposite to distance between the wall foot and the ladder.
θ = x⁰
opposite = 10 ft
hypotenuse = 20 ft
so,
Sin(x) = 10/20
sin(x) = 1/2
find the sine inverse of (0.5)
x = sin⁻¹(0.5)
x = 30⁰
The value of ∠x is 30⁰. Option B is correct.

a ≤ 20 and a ≥ 25
Answer:
ok so for a ≤ 20 it is A is less than or equal to 20
a ≥ 25 is A is greater than or equal to 25
Step-by-step explanation:
whenever you have a symbol like ≥, where it has a line under it, it means it could be equal to. And when the symbol is like a<20 (where < is the alligator it eats the bigger number so 20 is larger) And this means a is less than but since there is ≥ then its Equal to as well. :) sorry if this is confusing i will be willing to further explain if needed.
Albert is building a table and 4 chairs. He will use 18 nails to build each chair and 42 nails to
build the table. He estimates that he will need roughly 180 nails. Does that sound about
right?
Yes.
No, it is much too high,
No it is much to low
Albert's estimate of 180 nails is much too high since the actual calculation shows that he only needs 114 nails for the table and four chairs.
Explanation:To determine if Albert's estimate of needing roughly 180 nails for building a table and 4 chairs is correct, we should calculate the total number of nails required for this project. For each chair, he will need 18 nails, and for the table, he will need 42 nails.
Therefore, the total number of nails needed for the chairs is:
18 nails/chair × 4 chairs = 72 nailsAnd the number of nails needed for the table is:
42 nailsAdding these together gives us:
72 nails + 42 nails = 114 nailsComparing this with Albert's estimate of 180 nails, we can see that his estimate is much too high.

Maria and Jeff collect data on the number of cars that pass through an intersection every Monday morning for 2 months. They record the findings as 78, 158, 63, 71, 56, 67, 75, and 64. They each use different methods to summarize the typical number of cars that pass through the intersection at the specified time and compare their findings. Jeff says that, on average, 79 cars pass through the intersection each Monday morning. Maria disagrees and says that the mean should not be used and uses the median instead to describe the typical number of cars that passes through the intersection on any given Monday morning.
A) What is the median value of the data?
Final answer:
The median value of the car counts recorded by Maria and Jeff is calculated by first ordering the data and then finding the average of the two middle numbers, leading to a median of 69 cars passing through the intersection.
Explanation:
The median is a measure of central tendency which is used when the data set has outliers or is not symmetrically distributed. To calculate the median of Maria and Jeff's data which includes the number of cars that pass through an intersection, we first need to arrange the data set in ascending order: 56, 63, 64, 67, 71, 75, 78, and 158. Since there are eight numbers, we take the average of the two middle numbers (67 and 71).
To find the median, we add 67 and 71 to get 138 and then divide by 2, which results in a median of 69 cars. Thus, according to Maria's method, on average, a typical number of cars that would pass through the intersection on a Monday morning would be 69.

For which equation is (4, 3) a solution?
O y=2x-1

Oy=2x-5
Oy= x + 3
Answer:
Given question is incomplete; here is the complete question.
What is the equation of the line that is perpendicular to the given line and passes through the point (3, 4)?
y = –1/3x + 5
y = –1/3x + 3
y = 3x + 2
y = 3x − 5
Line given in the graph passes through the points (-3, 2) and (0, 1).
Slope of the given line =
m =
m =
Let the equation of a line perpendicular to this line is,
y - y' = m'(x - x') [Given line passes through (x', y')]
By the property of perpendicular lines,
m × m' = -1
() × m' = -1
m' = 3
Equation of the perpendicular line will be,
y - 4 = 3(x - 3)
y - 4 = 3x - 9
y = 3x - 5
Option (4) will be the answer.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
we have to put x= 4 and y= 3 in each equation.
1. y= 2x- 1
2x- 1 = 2(4)- 1 = 8- 1 = 7
y = 3
2. y = 3x - 4
3x - 4= 3(4) - 4 = 8
y= 3
3. y = 2x - 5

In isosceles △ABC with AC = AB, points D ∈ AB and E ∈ AC so that DB = EC. Point P is the intersection point of DC and EB, m∠ADC = 107°, m∠ABE = 45°. Find m∠BAP.
Please show work.
9514 1404 393
Answer:
14°
Step-by-step explanation:
∠ADP is an external angle to ΔDBP, so ...
∠ADP = ∠DBP + ∠DPB
107° = 45° + ∠DPB
∠DPB = 107° -45° = 62°
∠DPB is an external angle to isosceles triangle PBC, so ...
∠DPB = 2×∠PBC
62° = 2×∠PBC
∠PBC = 62°/2 = 31°
Of course, the angle sum theorem applies at vertex B, so ...
∠ABC = ∠ABP +∠PBC
∠ABC = 45° +31° = 76°
AP is the angle bisector of angle A, so, if extended to BC would be perpendicular to BC. Then ∠BAP is complementary to ∠ABC:
∠BAP = 90° -∠ABC
∠BAP = 90° -76°
∠BAP = 14°
Final answer:
m∠BAP = 124°
Explanation:
Given that △ABC is an isosceles triangle with AC = AB and DB = EC, we can conclude that △ADC and △AEB are congruent triangles by the Side-Angle-Side (SAS) congruence theorem. Therefore, m∠ADC = m∠AEB. Since m∠ADC = 107° and m∠AEB = 45°, we can write:
m∠ADC = m∠AEB
107° = 45° + m∠ABD
m∠ABD = 107° - 45°
m∠ABD = 62°
Since △ABD is isosceles with AB = AD, we have m∠ABD = m∠ADB. Therefore, m∠ADB = 62°. Since m∠BAP is an exterior angle of △ABD, we can apply the Exterior Angle Theorem to find:
m∠BAP = m∠ADB + m∠ABD
m∠BAP = 62° + 62°
m∠BAP = 124°

Answer:
The probability of getting heads on the toss of a coin is 0.5. If we consider all possible outcomes of the toss of two coins as shown, there is only one outcome of the four in which both coins have come up heads, so the probability of getting heads on both coins is 0.25.

A kangaroo hop 3520 yards to the lake with her baby in her pouch shop the remaining 5280 hours without her baby in her pouch how many miles did the kangaroo hop to the lake
Answer:
The kangaroo hopped a total of 5 miles to the lake.
Explanation:
To convert yards to miles, we can use the conversion factor that 1 mile is equal to 1760 yards.
So, to find out how many miles the kangaroo hopped to the lake, we first sum the distance with and without the baby in her pouch:
Total distance = Distance with baby + Distance without baby
Total distance = 3520 yards + 5280 yards
Total distance = 8800 yards
Now, we convert this total distance to miles:
Total distance in miles = Total distance in yards / 1760 yards/mile
Total distance in miles = 8800 yards / 1760 yards/mile
Total distance in miles = 5 miles
Therefore, the kangaroo hopped a total of 5 miles to the lake.
