Is the ratio 4.2:1.5 proportional to the ratio12.6:4.5? Explain.
Answer:
No
Step-by-step explanation:
All the numbers have to be multiplied by the same amount for it to be proportional
A proportional amount to 4:2:1:5 would be 12:6:3:15
They have all been multiplied by the same number 3
Answer:
Yes, the ratio is proportional
Step-by-step explanation:
given 4.2 : 1.5 =? 12.6 : 4.5 is it proportional
it must follow the means extremes property
[tex]\frac{a}{b}[/tex] = [tex]\frac{c}{d}[/tex]
a*d = b*c, so let's plug in the values
[tex]\frac{4.2}{1.5}[/tex] =? [tex]\frac{12.4}{4.5}[/tex]
(4.2)*(4.5) =? (1.5)*(12.6)
18.9 = 18.9 which is true; therefore the ratio is proportional

Step-by-step explanation:
You look at real estate ads for houses in Naples, Florida. There are many houses ranging from $200,000 to $500,000 in price. The few houses on the water, however, have prices up to $15 million. The distribution of house prices will be:_____. a. skewed to the left.b. roughly symmetric.c. skewed to the right.
Answer:
d. skewed to the right with possible outliers
Step-by-step explanation:
The distribution of house prices will be skewed to the right with possible outliers. This is because the regular median prices are still fairly far apart from each other with roughly $300,000 in difference between them. Also since there are some extreme house prices also included that greatly surpass the normal range these would be considered outliers in the data set.

These are the first 5 terms of sequence
Find(a)6th term
(b)nth term
(c)which term is equal to -332
Answers
A 3
B t = -7n +39
C 51.571
It is declining!
32 to 25 decreases by 7
25 to 18 decreases by 7
18 to 11 decreses by 7
The sequence is linear!
39 is the 0th term and our numbers are decreasing by 7 each term.
t = -7n +39 is our equation
a) -7(6) + 39
-49 + 39
3
b) to find nth term replace the term with n in this equation:
t = -7n +39
c) -332 = -7n +39
Subtract 39 from both sides!
-361 = -7n
Divide both sides by -7!
n = 51.571
The 6th term will be equal to -3, the nth term of the sequence will be equal to -7n + 39 and the term will be the 53rd term.
What is the arithmetic sequence?Two definitions are given for an arithmetic sequence. A "series where the variances in between every two succeeding terms are the same" is what it is.
Each term in an algebraic expression is created by multiplying its previous term by a specified integer (either positive, negative, or zero).
As per the given information in the question,
The sequence is given as:
32, 25, 18, 11, 4
(a)
a = 32
d = 25 - 32 = -7
n = 6
Then,
a₆ = a + (n - 1)d
a₆ = 32 + (6 - 1)(-7)
= 32 - 35
= -3
(b)
Find the nth term.
[tex]a_n[/tex] = a + (n - 1)d
= 32 + (n - 1)(-7)
= 32 -7n + 7
[tex]a_n[/tex] = -7n + 39
(c)
-332 = 32 + (n - 1)(-7)
-332 - 32 -7 = -7n
n = -371/-7
n = 53rd term.

If 1 yard = 3 feet and 1 mile = 5,280 feet, how many yards are there in 5 miles? (3 points)
A. 79,200 yards
B. 26,400 yards
C. 8,800 yards
D. 352 yards
Answer:
there are 8800 yards in 5 miles
Step-by-step explanation:
there are 1760 yards in a mile and multiply that by 5 to get 8800
its C because if you multiply 5280 by 5 is 26400 feet in 5 miles but we need yards so then we divide 26,400 by 3 witch is
Awnser: 8,800 yards or C
What is the equation of the line that passes through the point (8,-4) and has a slope of 1/2
The equation of the line that passes through the point (8,-4) and has a slope of 1/2 is; y = -x/2 - 2
What is the Point-slope form?The equation of the straight line has its slope and given point.
If we have a non-vertical line that passes through any point(x1, y1) and has a gradient m. then general point (x, y) must satisfy the equation
y-y₁ = m(x-x₁)
This is the required equation of a line in a point-slope form.
We know that Point-Slope Form:
y - y₁ = m(x- x₁)
Where x₁ - x coordinate and y₁ - y coordinate
m - slope
Point (8,-4)
Then Slope m = 1/2
Now the equation as;
y + 4 = 1/2(x - 8)
y = -1/2(x -4) - 4
y = -x/2 + 2 - 4
y = -x/2 - 2
Hence, the equation of the line that passes through the point (8,-4) and has a slope of 1/2 is; y = -x/2 - 2
