A credit card offer comes in the mail with the bold print "0% A.P.R. for New Accounts." Which important piece of information should you find before thinking about signing up?
Answers
"What is the A.P.R. after the introductory period ?" you find before thinking about signing up.
An introductory APR seems to be a special rate of interest offered by credit card providers to prospective clients for something like a predetermined period of months following opening a bank account.Numerous credit cards provide promotional APRs upon expenditures buying products, debt transfers, or sometimes both. Such rate was considerably cheaper than the estimated APR, typically as minimal as 0%.
Thus the response above is right.

EDGE
Answers
In the first step apply the distributive property or FOIL to find zw. Option C is correct.
Given that,
Let z = 19 + i and w = 4 + 10i.
The first step is to be determined.
The number that constitute of real and imaginary numbers are called a complex numbers. Complex number is represents as z = a + ib, where a = real number and bi = imaginary number
z = 19 + i and w = 4 + 10i
in order to find the product of complex numbers z and w following are the steps,
z.w = ( 19 + i )( 4 + 10i )
Step ⇒ 1
Applying distributive law,
z.w = 19 * ( 4 + 10i ) + i * ( 4 + 10i )
Step ⇒ 2
opening the parenthesis,
z.w = 19 * 4 + 19*10i + i * 4 + i * 10i
similarly, further steps are
z.w = 76 + 190i +4i + 10i²
since i² = -1
z.w = 76 + 194i - 10
z.w = 66 + 194i
Thus, in the first step apply the distributive property or FOIL to find zw. Option C is correct.

Answers
Răspuns:

Explicație pas cu pas:
Fie numărul = x
x + 4 = e - - (1)
e * 4 = f - - - (2)
Ecuația 2 - 4 împărțită la 4 = 4
(f - 4) / 4 = 4
Crucea se înmulțește
f - 4 = 16
f = 16 + 4
f = 20
Rezultatul 1 împărțit la 4 este egal cu 4
Prin urmare,
e = f / 4
f = 20
e = 20/4
e = 5
De la (1)
x + 4 = e
x + 4 = 5
x = 5 - 4

(b) Determine the quartiles.
(c) Compute and interpret the interquartile range, IQR.
(d) Determine the lower and upper fences. Are there any outliers?
Answers
Answer:
A) Z = -0.24
We can interpret this as the z-score corresponding to the individual who obtained 38. 1 miles per gallon is -0.24.
B) Q1 = 36.8 and Q3 = 41
C)IQR = 4.2
This means that the distance between the first and third quartile is 4.2
D) LF = 30.5 and UF = 47.3
the only outlier is 48.9 which is more than UF
Step-by-step explanation:
We are given the data representing the miles per gallon of a random sample of cars with a three-cylinder as;
32.7, 35.7, 38.0, 38.7, 40.1, 42.3, 34.3, 36.2, 38.1, 39.0, 40.6, 42.9, 34.5, 37.4, 38.3, 39.4, 41.4, 43.4, 35.3, 37.6, 38.5, 39.7, 41.7, 48.9
Sum of data is;
ΣX = 32.7 + 35.7 + 38.0 + 38.7 + 40.1 + 42.3 + 34.3 + 36.2 + 38.1 + 39.0 + 40.6 + 42.9 + 34.5 + 37.4 + 38.3 + 39.4 + 41.4 + 43.4 + 35.3 + 37.6 + 38.5 + 39.7 + 41.7 + 48.9 = 934.7
Formula for mean is;
μ = ΣX/n
μ = 934.7/24
μ = 38.95
Formula for sample standard deviation of is;
s = √[(1/(n - 1))Σ(X - μ)²]
From online calculator, we have a value of;
s = 3.505
A) Formula for z-score is;
Z = (x - μ)/s
We are given x = 38.1
Thus;
Z = (38.1 - 38.95)/3.505
Z = -0.24
We can interpret this as the z-score corresponding to the individual who obtained 38. 1 miles per gallon is -0.24.
B) Arranging the set of given values in ascending order, we have;
32.7, 34.3, 34.5, 35.3, 35.7, 36.2, 37.4, 37.6, 38.0, 38.1, 38.3, 38.5, 38.7, 39.0, 39.4, 39.7, 40.1, 40.6, 41.4, 41.7, 42.3, 42.9, 43.4, 48.9
Number of data; n = 24
First quartile is;
Q1 = ((n + 1)/4)th = ((24 + 1)/4)th = 25/4 = 6.25th term
Thus, we will find the average of the 6th and 7th term;
Q1 = (36.2 + 37.4)/2
Q1 = 36.8
Similarly;
Q3 = ¾(n + 1)th = ¾(24 + 1)
Q3 = ¾ × 25 = 18.75th term
Thus, we will find the average of the 18th and 19th term.
Q3 = (40.6 + 41.4)/2
Q3 = 41
C) Formula for inter quartile range is;
IQR = Q3 - Q1
IQR = 41 - 36.8
IQR = 4.2
This means that the distance between the first and third quartile is 4.2
D) Formula for lower fence is;
LF = Q1 - (1.5 × IQR)
LF = 36.8 - (1.5 × 4.2)
LF = 30.5
Formula for upper fence is;
UF = Q3 + (1.5 × IQR)
UF = 41 + (1.5 × 4.2)
UF = 47.3
Now, an outlier will be any values in the given set less than LF or more than UF.
From the given set, the only outlier is 48.9 which is more than UF

The sum of two numbers is 47. The greater number is 9 more than the smaller number. Which equation can be used to solve for the smaller number? x + (x + 9) = 47 x − (x + 9) = 47 x(x + 9) = 47 x(x − 9) = 47
Answers
I believe the correct answer from the choices listed above is the first option. The equation that can be used to solve the problem would be x + (x + 9) = 47.
The sum of two numbers is 47. ---> x + y = 47 where x is the smaller number and y is the larger.
The greater number is 9 more than the smaller number. -----> y = x + 9
x + ( x + 9 ) = 47

Subtract 8 from me. Then add 21. If you divide me by 4 and add 21 you get 29. What number am I?
Answers
Answer:
19
Step-by-step explanation:
x - 8 + 21 ÷ 4 + 21 = 29
x - 8 + 21 ÷ 4 = 29 - 21
= 8
x - 8 + 21 = 8 x 4
= 32
x - 8 = 32 - 21
= 11
x = 11 + 8
= 19
Therefore the number is 19. A bit confusing to me at first but I solved it :)

Which of the following inequalities matches the graph? (1 point)
x<2
y>2
x<2
x>2
Answers
Answer:
The inequality x>2 matches the graph.
Step-by-step explanation:
From the graph, it is clear that the shaded graph is heading towards the +ve infinity from the x > 2.
If the inequality includes < or >, we graph the equation as a dotted line.
From the graph, the dotted line indicates that x=2 is not included in the solution of the inequality.
so the interval of the domain of the inequality is: (2, ∞)
Therefore, the inequality x>2 matches the graph.
A plane flies at a steady rate of 40 mph while a second plane flies at a steady rate of 100 mph. The planes are 200 miles apart and fly directly toward each other. In how many hours will they meet?
plz help
times almost up
Answers
Answer:
The time the two planes will meet is 1.43 hours
Step-by-step explanation:
Given;
speed of the first plane in positive direction, = 40 mph
speed of the second plane in negative direction(opposite direction) = -100 mph
distance between the two planes = 200 miles
Let the time the two planes will meet = t
the position of the first plane at this time "t" = 40t
the position of the second plane at this time "t" = -100t
(40t)>--------------------------------<(-100t), this space between them is 200 miles.
Thus, the difference in the distance they traveled before meeting should be equal to 200 miles.
40t - (-100t) = 200
40t + 100t = 200
140t = 200
t = 200 / 140
t = 1.43 hours
Therefore, the time the two planes will meet is 1.43 hours
