Determine the number of days for which smoothie demand is an outlier (depending on 95% confidence interval)
Answers
The number of days for which smoothie demand is an outlier is the number of days when the demand for a smoothie is either less than 30 cups or more than 70 cups.
To determine the number of days for which smoothie demand is an outlier, depending on the 95% confidence interval, one needs to know the expected demand for a smoothie and the standard deviation of the demand for the smoothie.
Let's say that the expected demand for a smoothie is 50 cups per day. And, the standard deviation of the demand for a smoothie is 10 cups per day.
Using the 95% confidence interval, the formula to calculate the lower and upper bounds of the demand for a smoothie would be:
Lower Bound: expected demand - (z-score x standard deviation)Upper Bound: expected demand + (z-score x standard deviation)Where the z-score for a 95% confidence interval is 1.96 (from the z-table).So,Lower Bound: 50 - (1.96 x 10) = 29.6 (rounded to 30)Upper Bound: 50 + (1.96 x 10) = 70.4 (rounded to 70)
Therefore, the number of days for which smoothie demand is an outlier is the number of days when the demand for a smoothie is either less than 30 cups or more than 70 cups. This would depend on the data available for smoothie demand.

We can set the two equations equal to each other and solve for x:
3+x = 3x+8
2x = -5
× = -5/2
Now that we have x, we can substitute it into either equation to solve for y:
y = 3 + (-5/2)
y = 1/2
Therefore, the solution to the system of
equations is x = -5/2 and y = 1/2.
Hello !
1. We have :\(y=3+x\\y = 3x + 8\)
2. We know that y = y\(\boxed{y=}3+x\\\boxed{y=} 3x + 8\)

Answers
When we say p < .05, it suggests that there is less than 5% chance in 100 that any differences found were not due to the hypothesized reason.
The probability value (p-value) is a statistical measure that aids researchers in determining the likelihood of obtaining a particular observation if the null hypothesis is true. A null hypothesis is a statement or assumption that an experiment's result has no relation to the parameters being tested or the population at large.
The significance level (alpha) of the statistical analysis determines whether or not to accept the null hypothesis. If the calculated p-value is less than the significance level, the null hypothesis may be rejected, indicating that there is a statistical difference between the two datasets. If the p-value is greater than the significance level, there is insufficient evidence to reject the null hypothesis.A p-value of less than 0.05 is considered statistically significant, indicating that the likelihood of getting the observed result due to chance is less than 5%.
The rejection region in a hypothesis test is set to this level, implying that if the p-value is less than 0.05, we can conclude with 95% confidence that the null hypothesis should be rejected.

according to a recent study from the centers for disease control on american adults, the proportion that have a mobile phone is 89%, the proportion that have a landline is 57%, and 2% have neither a landline nor a mobile phone. what proportion of american adults have a mobile phone, and not a landline?
Answers
Approximately 34% of American adults have a mobile phone but not a landline, based on the given proportions from the study conducted by the Centers for Disease Control.
The proportion of American adults who have a mobile phone but not a landline, we need to subtract the proportion of those who have both a mobile phone and a landline from the proportion of those who have a mobile phone.
Let's denote the proportion of American adults who have a mobile phone as P(M), the proportion who have a landline as P(L), and the proportion who have neither as P(N).
Given information:
P(M) = 89% (proportion with a mobile phone)
P(L) = 57% (proportion with a landline)
P(N) = 2% (proportion with neither)
We can now calculate the proportion of adults who have a mobile phone but not a landline using the following equation:
P(M and not L) = P(M) - P(M and L)
To find P(M and L), we can subtract P(N) from P(L) since those who have neither are not included in the group with a landline:
P(M and L) = P(L) - P(N)
P(M and L) = 57% - 2%
P(M and L) = 55%
Now we can substitute the values back into the equation to find P(M and not L):
P(M and not L) = P(M) - P(M and L)
P(M and not L) = 89% - 55%
P(M and not L) = 34%

The required number of children and adults for sitting in the theater are 300 and 50 respectively.
Explain linear equation of two variable.A equation is supposed to be linear equation in two factors in the event that it is written as hatchet + by + c=0, where a, b and c are genuine numbers and the coefficients of x and y, i.e an a and b separately, are not equivalent to nothing. For instance, 10x+4y = 3 and - x+5y = 2 are straight equation in two factors.
According to question:Let be consider number of children be x and that of adults is y.
We have,
x + y = 350-------(1)
y = 350 - x
And 5x + 10y = 2000------------------(2)
Put value of y in equation (2)
5x + 10( 350 - x) = 2000
5x + 3500 - 10x = 2000
-5x = -1500
x = 300
Then
y = 350 - x = 350 - 300 = 50

Sum of multiplied differences= -962.676 and β1 = -962.676 / ((-18.381)^2 + (22.619)^2 + (-13.381)^2 + (-10.381)^2 + (10.619)^2 + (2.619)^2 + (28.619)^2 + (-17.381)^2 + (-17.381)^2 + (-9.381)^2 + (0.619).
To estimate the parameters of the model, we can use the following steps:
Calculate the mean of the first test scores and the mean of the second test scores.
Calculate the difference between each student's first test score and the mean first test score, and the difference between each student's second test score and the mean second test score.
Multiply the differences from step 2 together for each student, and sum the results.
Divide the sum from step 3 by the sum of the squares of the differences from step 2. This will give us the value of β1.
Calculate β0 by substituting the values of β1 and the mean first and second test scores into the equation: Second Test Grade = β0 + β1(First Test Grade)
Using these steps, we can calculate the estimates of the parameters as follows:
Mean first test score = (50+91+55+58+79+70+97+51+51+59+69+56+56+41+49+58+58+99+87+95+97)/21 = 68.381
Mean second test score = (70+58+74+65+60+60+48+73+73+66+67+70+73+76+72+68+73+53+58+50+55)/21 = 64.762
Difference between student 1's first test score and mean first test score = 50 - 68.381 = -18.381
Difference between student 1's second test score and mean second test score = 70 - 64.762 = 5.238
Difference between student 2's first test score and mean first test score = 91 - 68.381 = 22.619
Difference between student 2's second test score and mean second test score = 58 - 64.762 = -6.762
Sum of multiplied differences = (-18.3815.238) + (22.619-6.762) + (-13.3818.238) + (-10.381-0.762) + (10.619*-6.238) + (2.619*-7.238) + (28.619*-16.762) + (-17.3819.238) + (-17.3819.238) + (-9.381*-0.762) + (0.619*-0.238) + (-2.3816.238) + (-2.3817.238) + (-27.38116.238) + (-18.3813.238) + (-10.381*-3.762) + (-10.3815.238) + (-10.3815.238) + (30.619*-11.762) + (18.619*-6.762) + (26.619*-14.762) + (28.619*-9.762) = -962.676
β1 = -962.676 / ((-18.381)^2 + (22.619)^2 + (-13.381)^2 + (-10.381)^2 + (10.619)^2 + (2.619)^2 + (28.619)^2 + (-17.381)^2 + (-17.381)^2 + (-9.381)^2 + (0.619)

Item 4 Identify the initial amount $a$ and the rate of growth $r$ (as a percent) of the exponential function $y=12\left(1.05\right)^t$ . Evaluate the function when $t=5$ . Round your answer to the nearest tenth.
Answers
Answer:
Initial amount = 12
Rate of growth = 5%
value of the function when t t = 5 is 15.3
Step-by-step explanation:
The standard exponential growth equation is expressed as;
y = A(1+r)^t
A is the initial amount
r is the rate of growth
t is the time
Given the expression y = 12(1.05)^t
On comparing with the general formula;
A = 12
Hence the initial amount is 12
Also;
1 + r = 1.05
r = 1.05 -1
r = 0.05
r = 0.05 * 100
r = 5%
The rate of growth is 5%
To evaluate the function when t = 5, we will substitute t = 5 into the given function as shown;
Recall that y = A(1+r)^t
y = 12(1.05)^5

The solution of the sum of the numbers will be 5.
How to do summation?To make the addition easier, we can first simplify the fractions by finding a common denominator. The smallest common multiple of 2, 3, and 4 is 12. We can rewrite the fractions with this denominator:
7/4 = (7/4) x (3/3) = 21/12
1/2 = (1/2) x (6/6) = 6/12
5/3 = (5/3) x (4/4) = 20/12
1/3 = (1/3) x (4/4) = 4/12
1/4 = (1/4) x (3/3) = 3/12
1/2 = (1/2) x (6/6) = 6/12
Now we can add the fractions together:
21/12 + 6/12 + 20/12 + 4/12 + 3/12 + 6/12
Combining like terms, we get:
60/12 = 5
So the sum of the original fractions is equal to 5.
