The balance on your business credit card was $215 before you purchased 5 new chairs for the office. Each chair cost $75.
What is the new balance on the credit card?
$160
$290
$375
$590
$700
Answer:
$590
Step-by-step explanation:
The credit card balance on the card is : $215.
You put on his charge 5 chairs that each cost $75.
So 75 * 5 = 375.
You have now added to your credit card balance of $375 and before you bought the chairs, it was $215. You must add these totals to get your new balance after purchasing 5 new chairs for the office.
375 + 215 = 590.

Solve the following equation and show your work: 17 = m + 5 - 3m
Step-by-step explanation:
17=m+5-3m
(collect the like terms)
17=m-3m+5
17=-2m+5
(move the variable to the left-hand side and change the sign)
2m+17=5
2m=5-17
(calculate the difference)
2m=-12
(divide by both sides)
Answer:
m=-6

Let S be the universal set, where: S={1,2,3,...,18,19,20}
Let sets A and B be subsets of S, where:
Set A={1,3,4,5,6,8,9,11,14,15,20}
Set B={1,2,5,6,8,9,11,13,14,15,16,18}
Find the following:
LIST the elements in the set (A∪B):
(A∪B)= { }
Enter the elements as a list, separated by commas.If the result is the empty set, enter DNE
LIST the elements in the set (A∩B):
(A∩B)={ }
Enter the elements as a list, separated by commas.If the result is the empty set, enter DNE
Answer:
A∪B = {1,2,3,4,5,6,7,8,9,11,13,14,15,16,18,20}
A∩B = {1,5,6,7,8,9,11,14,15}
Step-by-step explanation:
A∪B is the elements in A or B. So, for this question, we just need to find the numbers that are in A or B. Remember not to add anything that is not in set A or B and not write the same number twice.
A∩B is the elements in A and B. Therefore, for this question, we just need to find the numbers which appeared in both set A and B.

What is the difference between the exact simple interest and the ordinary simple interest on a 200-day loan of 5,000 at 12%
Answer:
4.56
Step-by-step explanation:
"Ordinary" interest will be more than "exact" interest because the number of days in a year is a smaller value. The difference will be ...
Io = Prt = 5000(0.12)(200/360) = 333.33
Ie = Prt = 5000(0.12)(200/365) = 328.77
The difference is ...
333.33 -328.77 = 4.56 . . . the difference in interest values
_____
Additional comment
The question asks for the difference between exact and ordinary interest, so the result is technically negative:
328.77 -333.33 = -4.56

Consider two coins, CH and CT . Suppose that coin CH has probability 0.6 of coming up heads and that coin CT has probability 0.3 of coming up heads. On each day, we will select one coin to flip and register the outcome. On the first day (day one), we will pick a coin at random (uniformly). On subsequent days, we will flip coin CH if the outcome the previous day was heads, and we will flip coin CT if the previous outcome was tails. Determine the probability that the coin flipped on the third day after the initial flip (i.e., on day four) is coin CH. State any independence assumptions you use. Explain.
Answer:
0.4305
Step-by-step explanation:
Let [tex]P(H_n)[/tex] and [tex]P(T_n)[/tex] be the probability of coming up head and tail respectively on day [tex]n[/tex].
On day four, the coin CH will be salected iff there in head as outcome on the previous day, i.e. on the day three.
So, actually the probability of salection of coin CH on day four is probability of coming up head on day three, [tex]P(H_3)[/tex].
On day 1, n=1:
As one coin is salected randomly from two coin, so, the probability of salection of one coin is 1/2=0.5.
[tex]P(H_1)[/tex] is the probability of salection of coin CH and coming up head or salection of coin CT and coming up head when tossed.
So, [tex]P(H_1)=0.5\times 0.6 + 0.5\times0.3=0.45[/tex].
As there is only two outcome on any day, head or tail, so
[tex]P(T_1)=1-P(H_1)=1-0.45=0.55[/tex]
On day two, n=2:
The probability of salection of any coin depends on the outcpme of previous day, i.e
Probability of salection of coin CH and CT on day two are
[tex]P(H_1)=0.45[/tex] and [tex]P(T_1)=0.55[/tex] respectively.
So, [tex]P(H_2)=0.45\times 0.6 + 0.55\times0.3=0.435[/tex].
As there is only two outcome on any day, head or tail, so
[tex]P(T_2)=1-P(H_2)=1-0.435=0.565[/tex]
Similarly, on day three, n=3:
The required probability is [tex]P(H_3)[/tex],
[tex]P(H_3)=P(H_2)\times0.6 + P(T_2)\times 0.3[/tex]
[tex]\Rightarrow P(H_3)=0.435\times0.6 + 0.565\times 0.3=0.4305[/tex]
Hence, the salection od coin CH on day four is 0.4305.

y = 3x2 − 18x − 19.
Part A: Show your work to complete the square of the function. (1 point)
Part B: Identify the vertex of the function. (1 point)
Part C: Explain how to determine the maximum or minimum value of the function. (2 points)
Answer:
A) y = 3(x -3)^2 -46
B) (3, -46)
C) look at the y-coordinate of the vertex
Step-by-step explanation:
A) Factor the leading coefficient from the variable terms.
y = 3(x^2 -6x) -19
Inside parentheses, add the square of half the x-coefficient. Outside, subtract the same value.
y = 3(x^2 -6x +9) -19 -3(9)
y = 3(x -3)^2 -46
__
B) Compared to the vertex form, ...
y = a(x -h)^2 +k
we find a=3, (h, k) = (3, -46).
The vertex is (3, -46).
__
C) The vertex is an extreme value (as is any vertex). The sign of the leading coefficient tells you whether the parabola opens upward (+) or downward (-). This parabola opens upward, so the vertex is a minimum.
If the leading coefficient is positive, the y-coordinate of the vertex is a minimum. If the leading coefficient is negative, the y-coordinate of the vertex is a maximum.

-8x+40>-16
Answer:
x<7
Step-by-step explanation:
−8x+40>−16
Step 1: Subtract 40 from both sides.
−8x+40−40>−16−40
−8x>−56
Step 2: Divide both sides by -8.
−8x / −8 > −56 / −8
x<7
Suppose a university advertises that its average class size is 31 or less. A student organization is concerned that budget cuts have led to increased class sizes and would like to test this claim. A random sample of 40 classes was selected, and the average class size was found to be 33.1 students. Assume that the standard deviation for class size at the college is 9 students. Using α=0.01, complete parts a and b below.
a. Does the student organization have enough evidence to refute the college's claim?

Answer:
H0: μ ____ ≤ 31

The z-test statistic is ____ 0.0369
The critical z-score(s) is(are) ____ ± 2.33
Because the test statistic _____________ falls within the critical values,
______do not reject, the null hypothesis.
Step-by-step explanation:
We want to find that the average class size is 31 or less so we set up our hypothesis as
H0: μ ____ ≤ 31
H1: μ ____ > 31 One tailed test
Here
Sample size = n= 40
Sample mean = x`= 33.1
Standard Deviation = σ= 9
Level of significance=∝= 0.01
The z-test statistic is ____ 0.0369
z= x`- u/σ/√n
z= 33.1-31/9/√40
z= 2.1/56.92099= 0.03689= 0.0369
Z∝ for one tailed test for 0.01 significance level is ± 2.33
The critical z-score(s) is(are) ____ ± 2.33
Since the calculated value falls in the acceptance region we accept H0: μ ≤ 31 and reject alternate hypothesis H1: μ > 31.
Because the test statistic _____________ falls within the critical values,
