Answer: x=2 Please mark as brainliest
Step-by-step explanation: 16+7+4x=x+3x+7
combine like terms: 23+4x=4x+7
get x to one side: 23=8x+7
subtract: 16=8x
divide: x=2
The area of a triangle with sides 11.1 inches, 7 inches and 84 degree angle between the given sides is 38.6 in²
An equation is an expression that shows the relationship between two or more variables and numbers.
The area of the triangle is given as:
Area of triangle = (ab * sin∝)/2
where a,b are the sides and ∝ is the angle between the sides, hence:
Area of triangle = (11.1 * 7 * sin84)/2 = 38.6 in²
The area of a triangle with sides 11.1 inches, 7 inches and 84 degree angle between the given sides is 38.6 in²

Answer:
(a)$13
(b) Loss of $4
Step-by-step explanation:
C(q) represents Cost of producing q units.
R(q) represents Revenue generated from q units.
P(q) represents Total Profit made from producing q units.
Marginal analysis is concerned with estimating the effect on quantities such as cost, revenue, and profit when the level of production is changed by a unit amount. For example, if C(q) is the cost of producing q units of a certain commodity, then the marginal cost, MC(q), is the additional cost of producing one more unit and is given by the difference
MC(q) = C(q + 1) − C(q).
Using the estimation
C'(q)≈[TeX]\frac{C(q+1)-C(q)}{(q+1)-q}[/TeX]=C(q+1)-C(q)
We find out that MC(q)=C'(q)
We can therefore compute the marginal cost by the derivative C'(q).
This also holds for Revenue, R(q) and Profit, P(q).
(a) If C'(50)=75 and R'(50)=88
51st item.
P'(50)=R'(50)-C'(50)
=88-75=$13
The profit earned from the 51st item will be approximately $13.
(b) If C'(90)=71 and R'(90)=67, approximately how much profit is earned by the 91st item.
P'(90)=R'(90)-C'(90)
=67-71= -$4
The profit earned from the 91 st item will be approximately -$4.
There was a loss of $4.

Answer:
A university was interested in examining the overall effectiveness of its online statistics course, along with the effectiveness of particular aspects of the course. First, the university wanted to see whether the online course was better than a standard course. Second, the university wanted to know whether students learned best using Excel, using RStudio, or using no statistical package at all. The university randomly selected a group of 30 students and administered one of the different variants of the course (i.e., traditional or online, coupled with one of the software options) to each student. The success of each variant was measured by the students' average improvement between a pre-test and a post-test. How many treatment groups are there in this study?
Option D is correct - There are 6 treatment groups in this study.
Step-by-step explanation:
The number of treatment groups is equal to the number of possible combinations of the values of the factors.
In the question given, we have two factors: type of instruction (traditional/online) and software (Excel/Minitab/none).
Since there are 2 values for 'type of instruction' and 3 values for 'software'. Hence the number of treatment groups = 2*3 = 6.
Answer:
The answer is D: 5
Step-by-step explanation:
-Online course,
-Program to use,
- Number of students,
-Administered variant,
-Measurement of the average student.
Answer:
n = 15
Step-by-step explanation:
(x^n)(x^5)^3 = x^30
(x^n)(x^15) = x^30
x ^ (n+15) = x^30
n + 15 = 30
n = 15
To do the question, you need to know the exponent rules, which are short cuts to be able to do exponent work.
If you raise a power to a power, then times the exponents.
If you are multiplying two terms with the same base (in this case, x; the base is the large font bottom number) then ADD the exponents.
