The price of the adult tickets will be $20.

The price of the child tickets will be $18

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

Three adult and four children pay $132.

And, Two adult and three children pay $94.

Now,

Let The price of the adult tickets = x

The price of the child tickets = y

So, We can formulate;

Three adult and four children pay $132.

⇒ 3x + 4y = $132  ..(i)

And, Two adult and three children pay $94.

⇒ 2x + 3y = $94  ..(ii)

From (i),

⇒ 3x + 4y = $132

⇒ 3x = $132 - 4y

⇒ x = 44 - 4/3y

Substitute above value in equation (ii),

⇒ 2x + 3y = $94

⇒ 2(44 - 4/3y) + 3y = $94

⇒ 88 - 8/3y + 3y = $94

⇒ 1/3y = 94 - 88

⇒ 1/3y = 6

⇒ y = 18

And, From (ii),

⇒ 2x + 3y = $94

⇒ 2x + 3 × 18 = $94

⇒ 2x = 94 - 54

⇒ 2x = 40

⇒ x = 20

Thus, The price of the adult tickets = $20.

The price of the child tickets = $18

Answer:

54

Step-by-step explanation:

To evaluate the numerical expression for (22+5) / (12-9)x6, we need to follow the order of operations. The first step is to perform any operations inside parentheses, so we start by calculating the expressions inside the parentheses on the left-hand side of the equation: (22+5) = 27. Then we move to the right-hand side of the equation and perform the operations inside the parentheses there: (12-9) = 3. Next, we perform any multiplications or divisions in the order that they appear from left to right, so we divide 27 by 3 to get 9. Finally, we perform any remaining multiplications or divisions in the order that they appear from left to right, so we multiply 9 by 6 to get the final result: 54. Therefore, the numerical expression for (22+5) / (12-9)x6 is 54.

Answer:Model A and 19%

Step-by-step explanation:

I saw the explanation on study island

The correct model for the probability is given as follows:

Model B.

The probability that Mat will hit at least one home run in a single game is about 0.19 = 19%.

A probability is calculated by the division of the number of desired outcomes by the number of total outcomes.

Mat hits a home run once every ten times at bat, and gets exactly two times at bat in every game, hence the total number of outcomes is of:

10² = 100.

This is why Model B is the correct model, as it has two trials of 10 outcomes, and each trial has a 0.1 probability of success.

The probability that he hits no home runs is of:

0.9² = 0.81.

Hence the probability of hitting at least one home run is of:

1 - 0.81 = 0.19 = 19%.

The average wait time before a person can use the GottaGo toilet is three minutes. This is calculated by subtracting the average usage time (two minutes) from the average time between uses (five minutes).

1. Calculate the total time the toilet is occupied by multiplying the average usage time (two minutes) by the average time between uses (five minutes). This gives a total time of 10 minutes.

2. Calculate the total time the toilet is available by subtracting the total time the toilet is occupied (10 minutes) from the total time between uses (five minutes). This gives a total time of five minutes.

3. Calculate the fraction of time the toilet is occupied by dividing the total time the toilet is occupied (10 minutes) by the total time between uses (five minutes). This gives a fraction of two-fifths (2/5).

4. Convert the fraction to a percentage by multiplying the fraction by 100. This gives a percentage of 40%. Therefore, the GottaGo toilet is occupied 40% of the time.

Time occupied = 2 minutes * 5 minutes = 10 minutes

Time available = 5 minutes - 10 minutes = 5 minutes

Fraction of time occupied = 10 minutes / 5 minutes = 2/5

Percentage of time occupied = 2/5 * 100 = 40%

The logistic regression classifier is a supervised learning algorithm used for binary classification. It is used to estimate the probability of an example belonging to one of two classes, typically 0 or 1. The output of the classifier, hθ(x), is a value between 0 and 1, which is interpreted as the probability of the example belonging to class 1. In the given case, the output of the classifier is hθ(x) = 0.7, which implies that the probability of the example belonging to class 1 is 0.7 (or 70%) and the probability of the example belonging to class 0 is 0.3 (or 30%).

No assumptions can be made because we do not know if the function is continuous or differentiable on those intervals.

Answer:

The answer to the previous question is -14. This is the result of evaluating the expression 3(x^2-6)+4xy when x=2 and y=-2.

Step-by-step explanation:

The given expression is 3(x^2-6)+4xy. Plugging in the values for x and y, we get 3(2^2-6)+4(2)(-2) = 3(-2)+(-8) = -6-8 = -14. Therefore, the result is -14 when x=2 and y=-2.

Answer: 3

Step-by-step explanation:

The 95% confidence interval for the difference between the two proportions is (0.056, 0.164)

Here, we are given that from the sample information for people under 18-

n₁  =  500

x₁ =  180

⇒ p₁  =  180/ 500    

p₁  =  0.36    

then,  

q₁  =  1 -  p₁    

q₁ =  0.64

Similarly, from the sample information for people over 18, we have-

n₂  =  600

x₂  =  150

⇒ p₂  =  150 / 600  

p₂ =  0,25  

then,

q₂  =  1 - p₂  

q₂ =  1 - 0.25  

q₂ = 0,75

Now, we conduct a hypothesis test as follows-

Null hypothesis (H₀) ⇒  p₁  =  p₂

Alternative Hypothesis (Hₐ) ⇒ p₁  ≠  p₂

Confidence interval =  95 %    

⇒ significance level (α) = 5 %  

α  =  0.05  

and α/ 2  =  0.025  

⇒ z at 95% significance level = 1.96 (from z tables)

Now, we calculate z statistic-

z(s)  =  (p₁ - p₂) / EED

EED = √[(p₁*q₁)n₁  +  (p₂*q₂)/n₂]

EED = √[( 0.36*0.64)/500  +  (0.25*0.75)/600]

EED = √[0.00046  +  0.0003125]

EED = 0.028

and (p₁  -  p₂) = 0.36 - 0.25  

= 0.11

Therefore,

z(s)  =  0.11 / 0.028

z(s) = 3.93

we can see that  z(s) > 1.96

⇒ z(s) is in the rejection region for H₀

Thus, we reject H₀. We can´t support the idea of equals means

Now, CI at 95 %  = (p₁ - p₂) ±  z(c) * EED

CI = (0.11 ± 1.96 * 0.028)

CI = (0.11 ± 0.054)

CI =  (0.056, 0.164)

Thus, the 95% confidence interval for the difference between the two proportions is (0.056, 0.164)

Suppose that during its flight, the elevation e (in feet) of a certain airplane and its time t, in minutes since takeoff, are related by a linear equation. Consider the graph of this equation, with time represented on the horizontal axis and elevation on the vertical axis. For each situation, decide if the slope is positive, zero, or negative.

a. First ball 200 m/s and second ball 400 m/s both in same direction

b. First ball 200 m/s opposite direction and second ball 0 m/s at rest

Now for elastic collision there is a formula including mass and velocity of first and second body.

Now,

m1 = mass of first body

m2 = mass of second body

u1 = initial velocity of first body

u2 = initial velocity of second body

v1= final velocity of first body

v2 = final velocity of second body

Formula for final velocities of both bodies are

v1 = [(m1-m2)/m1+m2)]*u1 + [(2m2)/(m1+m2)]*u2

v2 = [(2m1)/(m1+m2)]*u1 + [(m2-m1)/m2+m1)]*u2

Now according to given data

u1 = 200 m/s

u2 = 0 m/s

For a)

consider m2 = 0 kg (in comparison, first ball is much massive, so the mass of second ball is negligible)

Now by putting values of m2, u1 and u2, we get

v1  = u1

v2 = 2u1

Since u1 = 200 m/s

v1 = 200 m/s

v2 = 400 m/s and both will move in same direction that is from where first body was coming towards second body.

For b)

Consider m1 = 0 Kg for same assumption

Now by putting values of m1, u1 and u2, we get

v1 = -u1

v2 = 0

So v1 = 200 m/s in opposite direction after collision with massive body

v2 = 0 m/s which means that massive body will not move after collision and will be at rest but smaller body will move in opposite direction after collision in double speed.

Answer:

2.5 gallons

Step-by-step explanation:

If Jason's family drinks 2 1/2 gallons of milk in 4 days, then the amount of milk they drink per day is 2 1/2 / 4 = 5/8 gallons. Since 1 gallon is equal to 128 fluid ounces, 5/8 gallons is equal to 5/8 * 128 = 80 fluid ounces. Therefore, Jason's family drinks 80 fluid ounces of milk per day.

Note: To convert a mixed number to a decimal, we need to divide the numerator of the fraction by the denominator and add the result to the whole number. In this case, the mixed number is 2 1/2, which is equal to 2 + 1/2 = 2 + 0.5 = 2.5. This means that Jason's family drinks 2.5 gallons of milk per day.

Answer:

Step-by-step explanation:

To find the distance between the complex numbers -3 + 5i and 2 - 9i, we can use the distance formula for complex numbers, which is given by:

d = sqrt((a - b)^2 + (c - d)^2)

where a, b, c, and d are the real and imaginary parts of the two complex numbers. In this case, a = -3, b = 2, c = 5, and d = -9, so we can substitute these values into the distance formula to get:

d = sqrt((-3 - 2)^2 + (5 + 9)^2)

= sqrt((-5)^2 + (14)^2)

= sqrt(25 + 196)

= sqrt(221)

= 11

Therefore, the distance between -3 + 5i and 2 - 9i is 11.

Estimating the entire amount of coal generated in the US between 1997 and 2009 is the goal.

The information shows how much cola is produced year, in billions of tons.

The right-hand sum and the left-hand sum must be calculated in order to estimate the amount of coal produced.

with n = 7 and a hand sum

(2009 - 1997)/7 = Delta*t

The difference between every two years in the table is 2, which is another way to calculate Ar. So. t*delta = 2

The total on the left is.

The formula is: Delta*t[1.09 + 1.094 + 1.121 + 1.072 + 1.132 + 1.147] = 2[1.09 + 1.094 + 1.121 + 1.072 + 1.132 + 1.147] =13.312.

The amount on the right is.

Delta*I[1.094 plus 1.121 plus 1.072 plus 1.132 plus 1.147 plus 1.073] = 2[1.094 plus 1.121 plus 1.072 plus 1.132 + 1.147 + 1.073] = 13.278

Thus, using the left-hand addition, the total amount of coal produced in the United States between 1997 and 2009 is 13.312; using the right-hand sum, it is 13.278.

To show the production of coal from 1997 to 2009, create an integral.

Production of coal lasted for 14 years, from 1997 to 2009 (2009 – 1997 = 14). As r = f(t) (t).

The correct options are:

b) If A and B are independent , then P(A|B)=P(A)

c) If A and B are disjoint, then they cannot be independent

d) If A and B are disjoint, then P(A cap B)=0

Explanation:

a) If A and B are disjoint, then P(A) and P(B) must not equal each other because the sets have no elements in common. This means that the probability of any given event happening in either set is 0, and so P(A) and P(B) cannot be the same.

b) If A and B are independent, then P(A|B) = P(A) because the event that occurs in A has no impact on the probability of the event occurring in B. This is because the two events do not affect each other, so the probability of one happening does not change with the occurrence of the other.

c) If A and B are disjoint, then they cannot be independent because the two sets have no elements in common. This means that the events in A can affect the probability of events in B and vice versa. For example, if an event in A occurs, then it is impossible for an event in B to occur at the same time. This means that the events are not independent.

d) If A and B are disjoint, then P(A cap B) = 0 because the two sets have no elements in common.

e) They must not be independent because, Disjoint events are events that have no elements in common, so they cannot be independent since they are not related in any way. This means that the probability of A given B is also zero, which means that A and B cannot be independent.
