Answer:
Six visits
Solving steps:
Question:. Francisco has a points card for a movie theater. He receives 55 rewards points just for signing up. He earns 9.5 points for each visit to the movie theater. He needs 112 points for a free movie ticket. How many visits must Francisco make to earn a free movie ticket?
Find out: How many visits required for 112 points.
Solution: Let's make an equation
=> 55 + 9.5x = 112
Let's make x the subject of formula
=> 9.5x = 112 - 55
Substract 55 from 112
=> 9.5x = 57
Divide both sides by 9.5
=> \( \frac{9.5x}{9.5} = \frac{57}{9.5} \)
Divide
=> x = 6
Therefore Francisco needs 6 visit to earn a free movie ticket
The number of visits Francisco must make to earn a free movie ticket is 6.
Given that, Francisco receives 55 rewards points just for signing up. He earns 9.5 points for each visit to the movie theater.
Let the number of visits to the movie theater be x.
In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.
The solution of an equation is the set of all values that, when substituted for unknowns, make an equation true.
He needs 112 points for a free movie ticket.
Now, the equation is \(9.5x+55=112\)
\(9.5x=112-55\)
\(9.5x=57\)
\(x=\frac{57}{9.5}\)
\(x=6\)
Therefore, the number of visits Francisco must make to earn a free movie ticket is 6.

Answer:
angle 1= 122
Step-by-step explanation:
We know this is an isosceles triangle because of the two marks indicating that the lines have the same measure and therefore have the same angle measurement as well.
Frist let's find the the 2 smaller sides by subtracting 64 from 180 and dividing by 2 (both sides are the same).
180-64=116, 116/2=58,
Now we know the measure of the smaller angles, and notice that the smaller angle on the forms a linear pair (both add up to 180 degrees) with angle 1
so, 180-58= angle 1
Angle 1= 122

When can a correlation coefficient based on an observational study be used to support a claim of cause and effect? Never When the correlation coefficient is close to -1 or +1. When the correlation coefficient is equal to -1 or +1. When the scatterplot of the data has little vertical variation.
Never. Correlation does not imply causation. A correlation coefficient based on an observational study can only be used to suggest a relationship between two variables, but it cannot be used to support a claim of cause and effect.
Correlation is a measure of the relationship between two variables. It is used to measure how two variables move together. A correlation coefficient based on an observational study can only be used to suggest a relationship between two variables, but it cannot be used to support a claim of cause and effect. This is because correlation does not imply causation. A correlation coefficient close to -1 or +1 is an indication of a strong linear relationship between the two variables, but this does not necessarily imply a cause-and-effect relationship. Additionally, even if the scatterplot of the data has little vertical variation, this does not guarantee a cause-and-effect relationship. In summary, correlation coefficients based on observational studies can never be used to support a claim of cause and effect.

Suppose you want to construct a 99% confidence interval for the proportion of first dates that lead to a second date. You want a margin of error of no more than plus or minus 2 percentage points. How many couples must you observe?
We need a sample size of at least 6644 couples to construct a 99% confidence interval for the proportion of first dates that lead to a second date, with a margin of error of no more than plus or minus 2 percentage points.
To find the required sample size for a given margin of error, we can use the following formula:
n = (z^2 * p * (1-p)) / (e^2)
where:
- n is the sample size
- z is the z-score associated with the desired level of confidence (99% in this case), which can be found using a standard normal distribution table or calculator
- p is the estimated proportion of first dates that lead to a second date (unknown in this case)
- e is the desired margin of error (2 percentage points in this case)
Since we don't have an estimate for the proportion of first dates that lead to a second date, we can use a conservative estimate of 0.5, which gives the largest possible sample size.
Using a z-score of 2.576 (for 99% confidence) and plugging in the other values, we get:
n = (2.576^2 * 0.5 * (1-0.5)) / (0.02^2) = 6643.06
Rounding up to the nearest integer, we need a sample size of at least 6644 couples to construct a 99% confidence interval for the proportion of first dates that lead to a second date, with a margin of error of no more than plus or minus 2 percentage points.

Convert the quadratic function from standard form to factored form. Y=x^2-2x-48.
Answer:
y=(x-8)(x+6)
Step-by-step explanation:
8 is a factor of 2, 6 adds up to 48
(also, my calculator can factor :P)
Hope this helps!
Answer:
y = (x - 8)(x + 6)
Step-by-step explanation:
In order to turn this into factored form, you need to find which two numbers add to -2 and multiply to -48. First, identify factors and see which ones have a difference of 2:
2 × 24
3 × 16
4 × 12
6 × 8
6 and 8 have a difference of 2 and multiply to 48. In order for them to add to -2 and multiply to -48 though, one must be negative. You can tell that 8 will be negative because -8 + 6 = -2 and -8 × 6 = -48.
At this point, you can write the factored form:
y = (x - 8)(x + 6)
(If you want to check your answer, you can just multiply the binomials using FOIL and see if they are the same as the given quadratic function)

The number of hurricanes that will hit a certain house in the next ten years is Poisson distributed with mean 4. Each hurricane results in a loss that is exponentially distributed with mean 1000. Losses are mutually independent and independent of the number of hurricanes. Calculate the variance of the total loss due to hurricanes hitting this house in the next ten years.
The variance of the total loss due to hurricanes hitting this house in the next ten years is 40,000,000.
To calculate the variance of the total loss due to hurricanes hitting the house in the next ten years, we can use the properties of the Poisson and exponential distributions.
Given:
Mean number of hurricanes in ten years (λ) = 4
Mean loss due to each hurricane (μ) = 1000
The variance of a Poisson distribution is equal to its mean (λ). So, the variance of the number of hurricanes in ten years is also 4.
The variance of an exponential distribution is equal to the square of its mean (μ²). So, the variance of the loss due to each hurricane is 1000² = 1,000,000.
Since the losses are mutually independent and independent of the number of hurricanes, we can use the properties of variance to calculate the variance of the total loss.
The total loss due to hurricanes in ten years is the sum of the losses from each individual hurricane. Since there can be a different number of hurricanes each year, we need to consider the total number of hurricanes as a random variable.
The total loss (X) can be expressed as:
X = L₁ + L₂ + ... + Lₙ
Where L₁, L₂, ..., Lₙ are the losses due to each individual hurricane.
Since the number of hurricanes is Poisson distributed with a mean of 4, the total number of hurricanes (N) in ten years is also Poisson distributed with a mean of 4 multiplied by 10 (mean number per year multiplied by the number of years).
N ~ Poisson(4 * 10) = Poisson(40)
The variance of a Poisson distribution is equal to its mean (λ). So, the variance of N is 40.
Now, we can use the properties of variance to calculate the variance of the total loss.
Var(X) = Var(L₁ + L₂ + ... + Lₙ)
Since the losses are independent, the variance of the sum is equal to the sum of the variances:
Var(X) = Var(L₁) + Var(L₂) + ... + Var(Lₙ)
Since each loss (Lᵢ) is exponentially distributed with a variance of 1,000,000, we can substitute:
Var(X) = 1,000,000 + 1,000,000 + ... + 1,000,000 (40 times)
Var(X) = 40 * 1,000,000
Var(X) = 40,000,000
Therefore, the variance of the total loss due to hurricanes hitting this house in the next ten years is 40,000,000.

find the solution set (2)
-6≥10-8x
The solution sets for the inequality 10+y<10-3y and -6≥10-8x are y>-2.5 and x≤0.75, respectively.
Inequality is a mathematical concept used to compare two expressions and determine whether one is larger or smaller than the other. It is represented by symbols such as <, >, ≤, and ≥.
To find the solution set of 10+y<10-3y, we must first isolate the variable y on one side of the equation.
To do this, we need to subtract 10 from both sides of the equation, leaving us with y<-10-3y.
We can then divide both sides by -4 to get
=> y>-2.5.
Thus, the solution set of 10+y<10-3y is y>-2.5.
To find the solution set of -6≥10-8x, we must first isolate the variable x on one side of the equation.
To do this, we need to subtract 10 from both sides of the equation, leaving us with
=> -6≥-8x.
We can then divide both sides by -8 to get
=> x≤0.75.
Thus, the solution set of -6≥10-8x is x≤0.75.
