18: x<32/5 19: c>-202
Step-by-step explanation:
\(x < \frac{32}{5}\\\)
\(c > -202\)
Step-by-step explanation:Solving \(x +\frac35 < 7\\\):
\(x +\frac35 < 7 \\ x +\frac35 -\frac35 < 7 -\frac35 \\ x < \frac{35}{5} -\frac35 \\ x < \frac{32}{5}\)
Solving for \(4 < 206 +c\):
\(4 < 206 +c \\ 206 +c > 4 \\ 206 +c -206 > 4 -206 \\ c > -202\)

(PLS HURRY!) On Melissa's 6th birthday, she gets a 2000$ CD that earns 6% interest, compounded. If the CD matures on her 14th birthday, how much money will be available?
Answers
Using compound interest formula when the CD matures on Melissa's 14th birthday, there will be $3187.69 available.
What is Compound Interest?The interest that is calculated using both the principal and the interest that has accrued during the previous period is called compound interest. It differs from simple interest in that the principal is not taken into account when determining the interest for the subsequent period with simple interest. Compound interest is commonly abbreviated C.I. in mathematics.
Use the formula for compound interest to calculate the amount of money that will be available when the CD matures -
\(A = P(1 + r/n)^(nt)\)
Where A is the amount of money available when the CD matures, P is the initial principal, r is the interest rate, n is the number of times the interest is compounded per year, and t is the time in years.
In this case, the initial principal is $2000, the interest rate is 6%, and the CD will be held for 8 years (from Melissa's 6th to 14th birthday).
It is not given how many times per year the interest is compounded, so assume it is compounded annually.
Using these values in the formula -
\(A = $2000(1 + 0.06/1)^(1*8)A = $2000(1.06)^8A = $3187.69\)
Therefore, the value is obtained as $3187.69.

If a categorical variable that can take the values from the set {Red, Blue, Green, Yellow} is included as an independent variable in a linear regression, the number of dummy variables that are created is: 2
Answers
If a categorical variable that can take the values from the set {Red, Blue, Green, Yellow} is included as an independent variable in a linear regression, the number of dummy variables that are created is two
When a categorical variable that has n categories is to be included as an independent variable in a linear regression analysis, it must be converted to n - 1 dummy variables. The reason for this is that including all n categories as dummy variables would cause perfect multicollinearity in the regression analysis, making it impossible to estimate the effect of each variable.In this case, the set of categories {Red, Blue, Green, Yellow} has four categories. As a result, n - 1 = 3 dummy variables are required to represent this variable in a linear regression. This is true since each category is exclusive of the others, and we cannot assume that there is an inherent order to the categories.The dummy variable for the first category is included in the regression model by default, and the remaining n - 1 categories are represented by n - 1 dummy variables. As a result, the number of dummy variables that are required to represent the categorical variable in the regression model is n - 1.
Thus, if a categorical variable that can take the values from the set {Red, Blue, Green, Yellow} is included as an independent variable in a linear regression, the number of dummy variables that are created is two .

jon and alex play a game where they each need to kick a ball into a net. they will each kick 11 balls, but alex has a slight edge, with a 60% chance of scoring to jon's 40%. what is the probability that jon will score exactly 8 times?
Answers
The probability of scoring a goal exactly 8 times by Jon is given by 0.0234. It is obtained using the prerequisite knowledge of binomial distribution and probability.
What is Binomial Distribution in Probability?
When each trial has a probability of occurring equally likely, then the number of trials or observations is outlined using the binomial distribution. The chance of observing a specific number of successful outcomes in a specific number of trials is determined by using the binomial distribution.
Calculation of the probability of the given event
Total no. of possible outcomes, n = 11
The probability that Jon will kick the ball in the net, p(x) = 0.4
The probability that Alex will kick the ball in the net, q(x) = 0.6
Using Binomial Distribution, we get,
P(x = r) = C(n,r) × (p)r × q(n - r)
where x is the score made by Joe
P(x = 8) = C(11,8) × (0.4)8 × (0.6)3
= 0.0234
Hence, the probability that Jon will score exactly 8 times is 0.0234.

Julie is 4 feet 2 inches tall. There are 2.54
centimeters in I inch. What is Julies height
in centimeters?
Answers
Step-by-step explanation:
4 ft 2 in = 50 inches
50 inches * 2.54 cm / in = 127 cm
It is found that Julie's height is 127 centimeters.
What is the fundamental principle of multiplication?If an event can occur in m different ways and if following it, a second event can occur in n different ways, then the two events in succession can occur in m × n different ways.
Given that Julie is 4 feet 2 inches tall and we need to change to centimeters.
First we change her height to inches:
\(\sf 1 \ Foot = 12 \ Inches\)
Therefore, 4 feet \(\sf = 4\times 12 = 48\) inches
The total height in inches = 48 inches + 2 Inches = 50 inches
Now, we have gotten her height in inches, change to centimeters.
We have that:
\(\sf 1 \ inch = 2.54 \ \bold{centimeters}\)
\(\sf 50 \ inches = 50 \times 2.54 \ cm\)
\(\sf= 127\ centimeters\).
Hence, Julie's height is 127 centimeters.

X is a continuous uniform random variable between the values 5 and 11.3. What is the probability X is more than or equal to 6.2? Round your answer to two decimal places.
Answers
From the given information provided, the probability that X is more than or equal to 6.2 is approximately 0.79.
The probability that X is more than or equal to 6.2 can be found by calculating the area under the probability density function of X to the right of 6.2. Since X is a continuous uniform random variable, the probability density function is a straight line with a slope of (1/(11.3-5)) = 1/6.3, and a y-intercept of 1/(11.3-5) = 1/6.3.
The area under the probability density function of X to the right of 6.2 is given by:
∫[6.2,11.3] (1/6.3) dx
= (1/6.3) [x]_[6.2,11.3]
= (1/6.3) (11.3 - 6.2)
= 0.79365
Rounding this to two decimal places, we get:
P(X ≥ 6.2) = 0.79

There is a strong terrible courting indicating that with a boom within the age of male adults, there may be an associated lower in the amount of hair on the top. Plot 1: r = 0.96, Plot 2: r = -0.87
In reading the relationship between the amount of water (X) in a fishpond and the quantity of habitat (Y), we'd anticipate the correlation between X and Y to be tremendous. This is because as the amount of water inside the pond will increase, it gives more sources and areas for the habitat to thrive, ensuing in an increase in the extent of habitat.
Regarding the correlational examination on person men with the variables of age (X) and amount of hair on the pinnacle (Y), a correlation coefficient of r = -0.80 indicates a robust poor courting.
This means that as the age of male adults will increase, there's a related decrease in the quantity of hair on the top. The poor correlation indicates that older males generally tend to have less hair on their heads as compared to younger men.
For the two plots furnished, the quality matches for the correlation coefficients are:

Answers
The underlying function f(x - i) that generates the observed points f'(x - i) in the plot can be determined by integrating the observed points. By integrating f'(x - i), we can obtain f(x - i) up to a constant of integration.
The constant of integration can be determined by incorporating additional information or constraints related to the problem or by considering the behavior of the function at a specific point.
To find the underlying function f(x - i) that generates the observed points f'(x - i), we need to integrate the observed points.
Integration is the reverse process of differentiation, so by integrating f'(x - i), we can recover f(x - i) up to a constant of integration.
The constant of integration arises because integration does not provide a unique solution.
The constant represents an arbitrary additive term that can vary depending on the specific problem or additional constraints.
To determine the constant of integration, we may need additional information or consider specific conditions related to the problem.
It is also important to note that the accuracy of estimating the underlying function f(x - i) depends on the quality and quantity of the observed data points f'(x - i). More data points and precise measurements can lead to a better estimation of the underlying function.
Additionally, the behavior of the function at a specific point can provide valuable insights for determining the constant of integration and refining the estimation of the underlying function.

Bagels: $5.00 x 30 = $150
$150 is the bagel profits.
The total sales are $395.00
To find the percentage of earnings due to bagel sales simply divide.
$150 / $395 = 0.3797

Caroline wants to buy 100 g of spice mix from a British or French website.
The conversion rate is €1 = £0.85
What is the price, including delivery costs, that Caroline would pay for the spice mix from the cheaper website? Give your answer in pounds (£).
British website: £0.90 for 25 g Free delivery.
French website: €1.20 for 50 g €0.80 delivery per order.
Answers
The website which is cheaper for Caroline to buy the spice mix is French website.
Given data ,
Let's calculate the total cost for Caroline from both websites and determine which one is cheaper.
British website:
Price for 100 g = (£0.90 / 25 g) * 100 g = £3.60
Since the British website offers free delivery, the total cost remains £3.60.
French website:
Price for 100 g = (€1.20 / 50 g) * 100 g = €2.40
Delivery cost = €0.80
On simplifying the equation , we get
To convert the price and delivery cost to pounds, we'll use the conversion rate: €1 = £0.85.
Price in pounds = €2.40 * £0.85 = £2.04
Delivery cost in pounds = €0.80 * £0.85 = £0.68
Total cost = Price in pounds + Delivery cost = £2.04 + £0.68 = £2.72
Comparing the total costs:
British website: £3.60
French website: £2.72
Hence , Caroline would pay £2.72 for the spice mix from the cheaper website, which is the French website.

A taxi ride costs $3 plus $2 for each mile driven. You spend $39 on a taxi. This can be modeled by the equation 2m + 3 = 39,
where m represents the number of miles driven. How long was your taxi ride?
Answers
39 = 2m + 3
Then we need to get the variable by itself by cancelling out the 3 on each side of the equation, like so:
39 - 3 = 2m + 3 - 3
Our simplified result would then be:
36 = 2m
*since we cancelled out the 3 on both sides we don’t need it to solve from here on out*
So then in order to get the ‘m’ by itself we must divide on both sides by 2 since the 2 is *multiplying* by ‘m’.
36/2 = 2m/2
Once simplified your answer would be:
18 = m
So now let’s check our answer since we know m=18:
39 = 2(18) + 3
39 = 36 + 3
39 = 39
This can verify that the ride was 18 miles long. Hope this helps! :)

A line is an one-dimensional figure. It has length but no width. A line can be made of a set of points which is extended in opposite directions to infinity. There are straight line, horizontal, vertical lines or may be parallel lines perpendicular lines etc.
A line with a slope of –1/4 passes through the point (–6,5)
Any line in point - slope form can be written as
y - y₁= m(x -x₁) -------(1)
where,
y= y coordinate of second point
y₁ = y coordinate of first point
m= slope of the line
x= x coordinate of second point
x₁ = x coordinate of first point
In the given problem (x₁ , y₁) = (-6,5) and m= -1/4
Putting all these values in equation (1) we get,
y-5= (-1/4) (x- (-6))
⇒ y-5 = -0.25(x+6)

Terms in math are the individual elements that are combined together to form an expression.
A term can consist of constants, variables, and/or operators. Examples of terms include 5, x, -2, and 6y + 3. When terms are combined to form an expression, they can be added, subtracted, multiplied, or divided. For example, the expression 3x + 5 can be read as "three times x plus five". This expression can be calculated by multiplying 3 and x and then adding 5, so if x = 10, then 3x + 5 = 35. Terms can also be combined in more complex expressions, such as (2y + 3)(4x - 5). This expression can be calculated by multiplying 2y + 3 and 4x - 5, which would result in 8yx - 15y + 12x - 15.
