The total cost for 6 movie tickets and 5 snacks is $97
The total cost for 6 movie tickets and x snacks is $(72 + 5x)
Given,
Miguel is going to see a movie with his 5 kids.
Number of people = 6
Cost for one ticket = $12
Cost of one snack = $5
Number of snacks = 5
We have to find the total cost spend by Miguel:
For tickets and 5 snacks:
For tickets and x snacks:
Now,
Total cost for tickets = 6 × 12 = $72
Cost for 5 snacks = 5 × 5 = $25
Therefore,
Total cost = 72 + 25 = $97
Next,
Cost for x snacks = 5x
Then,
Total cost = 72 + 5x
That is,
The total cost for 6 movie tickets and 5 snacks is $97
The total cost for 6 movie tickets and x snacks is $(72 + 5x)

in the presence of changing variability, the estimated standard errors of the ols estimators are inappropriate. what does this imply about using standard testing?
The error term, which refers to the sum of the deviations within the regression line and explains the discrepancy between the theoretical value of the model and the actual observed results, denotes the margin of error inside a statistical model.
What does OLS regression's error term mean?The error term, often referred to as the residual, disturbance, or remaining term, is denoted by the letters e,, or u in various ways in models.Use of an Error Term in a Formula : An error term basically denotes that the model is not entirely precise and yields varying outcomes when used in practical applications. Assume, for instance, that a multiple linear regression function has the following shape:Y=αX+βρ+ϵ
where:
α,β=Constant parameters
X,ρ=Independent variables
ϵ=Error term
During an empirical test, if the actual Y is different from the expected or projected Y in the model, the error term does not equal 0, indicating that other factors affect Y.The OLS estimators will continue to be linear, impartial, and consistent in the presence of autocorrelation. However, because to the absence of a minimal variance, the estimators will no longer be BLUE. It implies that the predictions made using the OLS estimators will be ineffective if the error terms are autocorrelated.To Learn more About error term refer to:

B) The total cost to stay for 6 nights is; $165
C) No, 3 night does not cost half as much as the cost for 6 nights due to the addition mandatory cost of $15.
How to solve algebra word problems?We are told that a pet hotel charges $25 per night to keep a dog. We are also told that there is a mandatory $15 examination fee when the dog arrives there.
A) If the number of nights spent is n, then the function rule here for the total cost is;
T = 25n + 15
B) We are told that the number of nights is 6 nights. Thus, we will just plug in 6 for n into the total cost equation to get;
T(6) = 25(6) + 15
T(6) = $165
C) The cost of 3 nights would be;
T(3) = 25(3) + 15
T(3) = $90
This is more than half of the cost of 6 nights.

B- below the mean by 2 points
C- below the mean by a distance equal to 2 standard deviations
D- above the mean by 2 points
Answer:
C- below the mean by a distance equal to 2 standard deviations
Step-by-step explanation:
The Z-score, or standard score, is the number of standard deviations a given data point lies above or below the mean.The z-score is positive if the value lies above the mean, and negative if it lies below the mean.So, a z-score of z = −2.00 indicates a position in a distribution below the mean by a distance equal to 2 standard deviations.A plant s 6.2cm tall.
The height of the plant increases by 11% each week
Find how tall the plant will be after 2 weeks
The height of plant will be 7.56cm tall after 2 weeks
How to calculate the height of the plant ?The original height of the plant is 6.2cm
The height increases by 11% each week
= 11/100
= 0.11
The increase of the plant in a week
= 0.11 × 6.2
= 0.682
The height of the plant after two weeks can be calculated as follows
= 0.682 + 0.682
= 1.364
= 6.2 + 1.364

jon's bathtub is rectangular and its base is 18 ft2. how fast is the water level rising if jon is filling the tub at a rate of 0.6 ft3/min? (use decimal notation. give your answer to three decimal places.)
Jon's bathtub exists rectangular and its base exists 18 ft². The water level rising if Jon is filling the tub at a rate of 0.2 ft³/min is 0.011 ft/min.
What is meant by differential equation?A differential equation in mathematics exists an equation that links the derivatives of one or more unknown functions. Applications often involve functions that reflect physical quantities, derivatives that depict the rates at which those values change, and a differential equation that establishes a connection between the three.
If we take a look at a rectangular bathtub, the volume of the bathtub can be expressed as:
Volume (V) = length × breadth × height
where; base = length × breadth = 18ft²
The volume of the rectangular bathtub = 18h ......... (1)
Using differentiation to differentiate 18h with respect to t implicitly, then:
[tex]$\frac{\mathrm{dV}}{\mathrm{dt}}=18 \frac{\mathrm{dh}}{\mathrm{dt}}$$[/tex]
When the rate of rising of the volume is 0.2 ft² / min
[tex]$0.2=18 \frac{\mathrm{dh}}{\mathrm{dt}}$$[/tex]
substitute the values in the above equation, we get
[tex]$\frac{\mathrm{dh}}{\mathrm{dt}}=\frac{1}{18} \times(0.2)$$[/tex]
[tex]$\frac{\mathrm{dh}}{\mathrm{dt}}=0.011 \mathrm{ft} / \mathrm{min}$$[/tex]
Therefore, we can conclude that the rate at which the water level rises if Jon is filling the tub at 0.2 ft³/min exists 0.011 ft/ min.

Answer:
(x - 3) (5x + 1)(x + 1).
Step-by-step explanation:
5x^3 - 9x^2 - 17x - 3
As the first coefficient is 5 and the last -3, so product is -15, we could try if (x-3) is a factor:
By the Factor Theorem, if x-3 is a factor then f(3) = 0.
f(3) = 5(3)^3 - 9(3)^2 - 17(3) - 3
= 135 - 81 - 51 - 3 = 0
So, x - 3 is a factor.
Now divide:
x - 3)5x^3 - 9x^2 - 17x - 3(5x^2 + 6x + 1 <------- Quotient
5x^3 - 15x^2
6x^2 - 17x
