Which of the following values of n will result in a true statement when substituted into the given equation? 4n + 9 = 1 A. n = -2 B. n = 2 C. n = 3 D. n = 4
Answers
Answer:
A. n = -2
Step-by-step explanation:
A. n = -2
4(-2) + 9 = 1
-8 + 9 = 1
1 = 1
The value of n for which the statement of equation 4n + 9 = 1 holds true is n = -2.
Given an equation:
4n + 9 = 1
There are some given options for the value of n.
It is required to find the value of n, where the statement is true.
A) When n = -2:
4n + 9 = 4(-2) + 9
= 1
B) When n = 2:
4n + 9 = 4(2) + 9
= 17
C) When n = 3:
4n + 9 = 4(3) + 9
= 21
D) When n = 4:
4n + 9 = 4(4) + 9
= 25
Hence the true statement is when n = -2.

Joanne sells silk-screened T-shirts at community festivals and craft fairs. Her marginal cost to produce one T-shirt is $ 2.50 . Her total cost to produce 60 T-shirts is $ 240 comma and she sells them for $8 each. a. Find the linear cost function for Joanne's T-shirt production. b. How many T-shirts must she produce and sell in order to break even? c. How many T-shirts must she produce and sell to make a profit of $600?
Answers
Answer:
a) c = 90 +2.50t
b) 17
c) 126
Step-by-step explanation:
a) We're told that the cost for 60 T-shirts is $240, but we know that the marginal cost for those 60 shirts is ...
60($2.50) = $150
Joanne seems to have fixed costs of $240 -150 = $90. So, her linear cost function seems to be ...
c = 90 +2.50t . . . . . . . where c is the cost to produce t shirts
__
b) Joanne's revenue function is ...
r = 8t
so her profit function is ...
p = r -c = 8t -(90 +2.50t)
p = 5.50t -90
This will be zero for ...
0 = 5.50t -90
0 = t -16.364
Joanne must produce and sell 17 T-shirts to cover her production cost.
__
c) Profit will be 600 when ...
600 = 5.50t -90
690 = 5.50t
690/5.50 = t = 125.455
Joanne must produce and sell 126 T-shirts to make a profit of $600.
_____
Comment on results
Note that fractional T-shirt sales are involved in making the numbers come out exactly. We have elected to round up, so that slightly more profit is made than the exact amounts of $0 or $600. Rounding to the nearest integer would give values one shirt less than what we have reported.

Answer: 3x^4+7x^3+7x^2+11x+4
Step-by-step explanation:
(x^2+3x+4)(3x^2-2x+1)
3x^4-2x^3+x^2+9x^3-6x^2+3x+12x^2-8x+4
Collect like terms
3x^4-2x^3+9x^3+x^2-6x^2+12x^2+3x+8x+4
3x^4+7x^3+7x^2+11x+4
Answer:
To multiply (x^2 + 3x + 4) and (3x^2 - 2x + 1), we need to distribute each term of the first polynomial to every term in the second polynomial:
(x^2 + 3x + 4)(3x^2 - 2x + 1)
= x^2 * (3x^2 - 2x + 1) + 3x * (3x^2 - 2x + 1) + 4 * (3x^2 - 2x + 1)
Now, let's simplify each term:
= 3x^4 - 2x^3 + x^2 + 9x^3 - 6x^2 + 3x + 12x^2 - 8x + 4
Combining like terms:
= 3x^4 + (-2x^3 + 9x^3) + (x^2 - 6x^2 + 12x^2) + (3x - 8x) + 4
= 3x^4 + 7x^3 + 7x^2 - 5x + 4
So, the product of (x^2 + 3x + 4) and (3x^2 - 2x + 1) is 3x^4 + 7x^3 + 7x^2 - 5x + 4.
Therefore, the correct answer is option C: 3x^4 + 7x^3 + 7x^2 - 5x + 4.

Two chemists working for a chicken fast-food company, have been producing a very popular sauce. Let’s call then Jesse and Mr. White. Gus, their boss, is tired of Mr. White’s negative attitude and is thinking about "firing" him and keeping only Jesse on the payroll. The problem, however, is that Mr. White seems to produce a higher quality sauce whenever he is in charge of production if compared to Jesse. Before making a final decision, Gus collected some data measuring the quality of different batches of sauce produced by Mr. White and Jesse. We assume the quality measurements for both of them are normally distributed with the common variance. The results, measured on a quality scale, are listed below:
Mr. White 97 1 7
Jesse 94 3 10
a. Based on this data, can we tell for sure (with 95% confidence) which one is the better chemist?
b. Gus wants to keep the mean quality score for the sauce above 90. In this case, can he can rid of Mr. White, i.e., is Jesse good enough to run the sauce production?
Answers
Answer:
Check the explanation
Step-by-step explanation:
Let [tex]\overline{x}[/tex] and [tex]\overline{y}[/tex] be sample means of white and Jesse denotes are two random variables.
Given that both samples are having normally distributed.
Assume [tex]\overline{x}[/tex] having with mean [tex]\mu_{1}[/tex] and [tex]\overline{y}[/tex] having mean [tex]\mu_{2}[/tex]
Also we have given the variance is constant
A)
We can test hypothesis as
[tex]H0: \mu_{1} = \mu_{2}H1: \mu_{1} > \mu_{2}[/tex]
For this problem
Test statistic is
[tex]T=\frac{\overline {x}-\overline {y}}{s\sqrt{\frac {1}{n1} +\frac{1}{n2}}}[/tex]
Where
[tex]s=\sqrt{\frac{(n1-1)*s1^{2}+(n2-1)*s2^{2}}{n1+n2-2}}[/tex]
We have given all information for samples
By calculations we get
s=2.41
T=2.52
Here test statistic is having t-distribution with df=(10+7-2)=15
So p-value is P(t15>2.52)=0.012
Here significance level is 0.05
Since p-value is <0.05 we are rejecting null hypothesis at 95% confidence.
We can conclude that White has significant higher mean than Jesse. This claim we can made at 95% confidence.
What is the slope of the line
Answers
Answer:
4/5
Step-by-step explanation:
There are so many points on the graph whose coordinates are impossible to estimate. Look for two "nice" points--points with integer coordinates. The line passes through (-2, 0) and (3, 4).
Slope = rise / run. It's the ratio of vertical change to horizontal change as you move from one point on the line to another.
Moving from (-2, 0) to (3, 4), the vertical change is 4 - 0 = 4.
The horizontal change is 3 - (-2) = 5.
The slope is 4/5

How many strings can be formed by ordering the letters MISSISSIPPI which
contain no two I’s are consecutive ?
Answers
Answer:
Total number of strings = 7350
Step-by-step explanation:
Given:
MISSISSIPPI
Required:
Number of strings to contain no two consecutive I's
To do this, we start by calculating the number of strings that can be formed without any I;
We're left with MSSSSPP
7 characters in total
4 S and 2 P
The number of strings is calculated as follows
Number of strings = [tex]\frac{7!}{4!2!}[/tex]
Number of strings = [tex]\frac{7*6*5*4!}{4!*2*1}[/tex]
Number of strings = [tex]\frac{7*6*5}{2*1}[/tex]
Number of strings = 7 * 3 * 5
Number of strings = 105
Then we count the number of possible spaces of I; This is as follows
-M-S-S-S-S-P-P-
This is represented by the - sign.
In total, there are 8 spaces, the 4 I's can occupy
There number of selection is as follows
[tex]\left[\begin{array}{c}8&\\4&\\\end{array}\right] = \frac{8!}{4!*4!}[/tex]
[tex]\left[\begin{array}{c}8&\\4&\\\end{array}\right] = \frac{8 * 7 * 6 * 5 * 4!}{4!*4*3*2*1}[/tex]
[tex]\left[\begin{array}{c}8&\\4&\\\end{array}\right] = \frac{8 * 7 * 6 * 5}{4*3*2*1}[/tex]
[tex]\left[\begin{array}{c}8&\\4&\\\end{array}\right] = 70[/tex]
Total number of strings = 105 * 70
Total number of strings = 7350

There were 632 animals gathered at the river. A herd of 187 elephants and 266 zebras left the river area. How many animals were still at the river?
Answers
Answer:
179 animals were still at the river
Step-by-step explanation:
There were 632 animals at the river.
A herd of 187 elephants and 266 zebras left the river area.
This means that 187 + 266 = 453 animals left the river area.
Remaining:
632 - 453 = 179
179 animals were still at the river
