Answer:
25 tickets
Step-by-step explanation:
Carnival M charges an entrance fee of $5.00 and $0.65 per ticket for the rides. Carnival P charges an entrance fee of $10.00 and $0.45 per ticket for the rides. How many tickets must be purchased in order for the total cost at Carnival M and Carnival P to be the same?
Let
x = number of tickets
Carnival M = 5 + 0.65x
Carnival P = 10 + 0.45x
Equate both cost
5 + 0.65x = 10 + 0.45x
5 - 10 = 0.45x - 0.65x
-5 = - 0.20x
x = -5 / -0.20
x = 25 tickets
25 tickets tickets must be purchased in order for the total cost at Carnival M and Carnival P to be the same
Determine if the question posed is a statistical question (yes) or not (no). How many apps do my classmates have on their phones?
Answer:
Statistical
Step-by-step explanation:
You need to collect data to determine the answer of that.
Answer:
Yes
Step-by-step explanation:
"How many apps do my classmates have on their phones?" This is a statistical question because a statistical question has to be a question that can be used to collect data. If the question was something like "How many apps does Melissa have on her phone?" it would NOT be a statistical question because it is only asking about one specific person and you wouldn't be collecting data.
I wasn't really sure how to explain it but I hope it makes sense! :)

Step-by-step explanation:
Two customers took out loans from a bank.
Jacob took out a 3-year loan for $8,000 and paid 4.2% annual simple interest
Christian took out a 5-year loan for $8,000 and paid 3.9% annual simple interest.
What is the difference between the amounts of interest Jacob and Christian paid for their loans?
A.635.59
B.1560.00
C.1008.00
D.552.00
The difference between the amounts of interest Jacob and Christian paid for their loans is $552.
To calculate the amount of interest paid by Jacob and Christian, we can use the simple interest formula:
Interest = Principal x Rate x Time
Where,
Principal: the amount of the loan
Rate: the annual interest rate
Time: the duration of the loan in years
For Jacob's loan:
Principal = \(\$8,000\)
Rate = 4.2%
Time = 3 years
Interest = \(\$8,000 * 4.2\% * 3 = \$1,008\)
Therefore, Jacob paid $1,008 in interest.
For Christian's loan:
Principal = \(\$8,000\)
Rate = 3.9%
Time = 5 years
Interest = \(\$8,000 * 3.9\% * 5 = \$1,560\)
Therefore, Christian paid $1,560 in interest.
The difference between the amounts of interest Jacob and Christian paid for their loans is:
\(\$1,560 - \$1,008 = \$552\)
Therefore, the answer is D. \(\$552\).

The cot of pen and three ruler i le29 while two ruler and ix pen cot le48. Find the cot of eight ruler and three pen
The cost of eight ruler and three pens is le79.125.
Let's call the cost of a pen x and the cost of a ruler y. From the first statement, we can create the equation:
x + 3y = 29
And from the second statement:
6x + 2y = 48
That is dividing by 2, 3x + y = 24
Now we have two equations with two variables and can use substitution or elimination method to find the values of x and y.
Let's use substitution:
x = 29 - 3y
Substituting this into the second equation:
3(29 - 3y) + y = 24
87 - 9y + y = 24
8y = 63
y = 63/ 8
y = 7.875
Now that we have the value of y, we can use the first equation to find the value of x:
x = 29 - 3y = 29 - 3 * 63/8
= 5.375
So, a pen costs le5.375 and a ruler costs le7.875. To find the cost of 8 rulers and 3 pens, we multiply:
8 * 7.875 + 3 * 5.375 = le79.125
The cost of 8 rulers and 3 pens is le79.125.

scientific research on popular beverages consisted of 65 studies that were fully sponsored by the food industry, and 35 studies that were conducted with no corporate ties. of those that were fully sponsored by the food industry, 13 % of the participants found the products unfavorable, 22 % were neutral, and 65 % found the products favorable. of those that had no industry funding, 36 % found the products unfavorable, 17 % were neutral, and 47 % found the products favorable. what is the probability that a participant selected at random found the products favorable? if a randomly selected participant found the product favorable, what is the probability that the study was sponsored by the food industry? if a randomly selected participant found the product unfavorable, what is the probability that the study had no industry funding?
To find the probability that a participant selected at random found the products favorable, we can calculate the weighted average of the favorable responses from both the industry-sponsored and non-industry-funded studies.
For the industry-sponsored studies, 65% of participants found the products favorable, and for the non-industry-funded studies, 47% found the products favorable. Since there were 65 industry-sponsored studies and 35 non-industry-funded studies, the overall probability is:
(65/100) * 0.65 + (35/100) * 0.47 = 0.4225 + 0.1645 = 0.587 or 58.7%
If a randomly selected participant found the product favorable, we can use Bayes' theorem to calculate the probability that the study was sponsored by the food industry given this favorable response. The calculation is:
P(Industry-sponsored | Favorable) = (P(Favorable | Industry-sponsored) * P(Industry-sponsored)) / P(Favorable)
P(Favorable | Industry-sponsored) = 0.65
P(Industry-sponsored) = 65/100
P(Favorable) = 0.587
P(Industry-sponsored | Favorable) = (0.65 * (65/100)) / 0.587 ≈ 0.719 or 71.9%
Similarly, if a randomly selected participant found the product unfavorable, we can use Bayes' theorem to calculate the probability that the study had no industry funding given this unfavorable response. The calculation is:
P(No industry funding | Unfavorable) = (P(Unfavorable | No industry funding) * P(No industry funding)) / P(Unfavorable)
P(Unfavorable | No industry funding) = 0.36
P(No industry funding) = 35/100
P(Unfavorable) = 1 - P(Favorable) = 1 - 0.587 = 0.413
P(No industry funding | Unfavorable) = (0.36 * (35/100)) / 0.413 ≈ 0.305 or 30.5%

11-32 (modified). A statistician is testing the null hypothesis that exactly half of all engineers will still be in the profession 10 years after receiving their bachelor's. She took a random sample of 200 graduates from the class of 1979 and determined their occupations in 1989. She found that 111 persons were still employed primarily as engineers. (a) Construct a 95% confidence interval estimate for the proportion of engineers remaining in the profession. (Ignore the continuity correction and use the formulas on p. 314.)
Lower limit =
Upper limit =
Using the given sample data, a 95% confidence interval estimate for the proportion of engineers remaining in the profession can be calculated. The lower and upper limits of this confidence interval will provide a range within which the true proportion is likely to fall.
To construct a confidence interval for a proportion, we can use the formula:
CI = p^ +- Z * sqrt((p^ * (1 - p^)) / n)
Where:
CI = Confidence Interval
p^= Sample proportion (proportion of engineers remaining in the profession)
Z = Z-score corresponding to the desired confidence level (95% confidence level corresponds to a Z-score of approximately 1.96)
n = Sample size (number of graduates in the sample)
Given data:
Sample size (n) = 200
Number of engineers still employed (x) = 111
First, calculate the sample proportion (p^):
p^ = x / n
Substituting the values:
p^ = 111 / 200 = 0.555
Next, calculate the standard error:
SE = sqrt((p^ * (1 - p^)) / n)
Substituting the values:
SE = sqrt((0.555 * (1 - 0.555)) / 200)
Finally, calculate the lower and upper limits of the confidence interval:
Lower limit = p^ - Z * SE
Upper limit = p^ + Z * SE
Substituting the values:
Lower limit = 0.555 - 1.96 * SE
Upper limit = 0.555 + 1.96 * SE
The specific values for the standard error, lower limit, and upper limit can be calculated using the provided formulas.
Therefore, the lower and upper limits of the 95% confidence interval estimate for the proportion of engineers remaining in the profession can be determined using the calculated values.

given f(5)=19, f′(5)=12, g(5)=10, and g′(5)=−13, find the value of h′(5) based on the function below.
h(x)=f(x)⋅g(x)
To find the value of h′(5) for the function h(x)=f(x)⋅g(x), we will use the Product Rule. The Product Rule states that for two functions u(x) and v(x), the derivative of their product, (u⋅v)'(x), is given by:
(u⋅v)'(x) = u'(x)⋅v(x) + u(x)⋅v'(x)
In this case, u(x) = f(x) and v(x) = g(x). Using the given information:
u(5) = f(5) = 19
u'(5) = f'(5) = 12
v(5) = g(5) = 10
v'(5) = g'(5) = -13
Now, applying the Product Rule for h′(5):
h'(5) = f'(5)⋅g(5) + f(5)⋅g'(5)
h'(5) = (12)(10) + (19)(-13)
h'(5) = 120 - 247
h'(5) = -127
So, the value of h′(5) is -127.

use partial fractions to find the power series of the function for 3/((x-2)(x 1))
The power series of the function 3/((x-2)(x+1)) is:
-3/4 - 1/4(x-2) + 1/4(x-2)² - 1/4(x-2)³- 1/2 - 1/2(x+1) - 1/2(x+1)² - 1/2(x+1)³ + ...
How to find the power series?To find the power series of the function 3/((x-2)(x+1)), we first need to find the partial fraction decomposition of the function:
3/((x-2)(x+1)) = A/(x-2) + B/(x+1)
To solve for A and B, we need to find a common denominator on the right-hand side:
3 = A(x+1) + B(x-2)
Setting x = 2, we get:
3 = A(3)
A = 1
Setting x = -1, we get:
3 = B(-3)
B = -1
Therefore, we have:
3/((x-2)(x+1)) = 1/(x-2) - 1/(x+1)
Now we can use the formula for the geometric series:
1/(1 - t) = 1 + t + t²+ t³ + ...
to write the power series of each term in the partial fraction decomposition. Substituting t = x-2 for the first term and t = -x-1 for the second term, we get:
1/(x-2) = -1/4 - 1/4(x-2) + 1/4(x-2)² - 1/4(x-2)³ + ...
1/(x+1) = -1/2 - 1/2(x+1) - 1/2(x+1)² - 1/2(x+1)³ - ...
Combining the two series, we have:
3/((x-2)(x+1)) = -3/4 - 1/4(x-2) + 1/4(x-2)² - 1/4(x-2)³ - 1/2 - 1/2(x+1) - 1/2(x+1)² - 1/2(x+1)³ + ...
Therefore, the power series of the function 3/((x-2)(x+1)) is:
-3/4 - 1/4(x-2) + 1/4(x-2)² - 1/4(x-2)³- 1/2 - 1/2(x+1) - 1/2(x+1)² - 1/2(x+1)³ + ...
