23 tickets are purchased for children and 9 tickets are purchased for adults.
Given,
In the question:
A group entering a zoo purchased 32 admission tickets for a total of $148. Adult tickets cost $7. 50, and tickets for children cost $3. 50.
To find the how many of each type of ticket were purchased?
Now, According to the question:
It is given in the question that 32 tickets are purchased by group which cost total $148.
Let the number of children of the group who are entering the zoo be x. Then the number of adults will be 32- x
Now cost of one ticket for adult = $7.50
Total amount spent on adult tickets = 7.50 × (32-x)
Similarly, cost of one ticket for child= $3.50
Total amount spent on children tickets = 3.50 × x =3.5x
Total amount spent by group on tickets = $148
⇒ 7.5 × (32-x) + 3.5x = 148
⇒ 240 - 7.5x + 3.5x = 148
⇒ 7.5x - 3.5x = 240 - 148
⇒ 4x = 92
⇒ x = 23
Children = 23
Adults = 32-x = 32-23 = 9
Hence, 23 tickets are purchased for children and 9 tickets are purchased for adults.

0.625 x 6 = 3.75
As a result the cost of 6 cans of sup is $3.75
As part of his semester project, a byu-idaho introductory statistics student calculates a 95% confidence interval for the true percentage of byu-idaho students who are from latin america. What does the phrase 95% confidence mean?.
"95% confidence interval" means that there is a 95% chance that the true fraction falls within the computed confidence interval.
Confidence Intervals: Confidence intervals are the range of estimates for unknown parameters.
Confidence intervals are more than just a range of estimated values. It also tells you how stable the estimates are. A stable estimate is an estimate that has approximately the same value if the study is repeated. An unstable estimate is one that would vary from one sample to another.
The confidence interval determines the range that one can be certain that contains the true mean of the population.
This means that, The 95% confidence means, there is a 95% chance that the true proportion will be in the calculated confidence interval or 95 percent confidence interval, you have a 5 percent chance of being wrong.
Hence, the true statement that represents "95% confidence interval" is chance of true fraction of sucess.

To find out what are the steps in solving the below inequality:
Given equation is 2x - 3 > 15
The absolute value function takes any term and transforms it to its non-negative form. Therefore, we must solve the term within the absolute value function for both its negative and positive equivalent.
−15≤2x-3≤15
First, subtract 3 from each segment of the system of equations to isolate the x term while keeping the system balanced:
−15−3≤2x-3−3≤15−3
−18≤2x-6≤12
−18≤2x-6≤12
Now, divide each segment of the system by 2 to solve for x while keeping the system balanced:
[tex]-\frac{18}{2}\leq \frac{2x}{2} \leq \frac{12}{2}[/tex]

A person invests 5000 dollars in a bank. The bank pays 6.25% interest compounded quarterly. To the nearest tenth of a year, how long must the person leave the money in the bank until it reaches 6500 dollars?
Based on the calculation below, the number of years the person must leave the money in the bank until it reaches 6500 dollars is 4.3 years.
How long must money be left in a bank to reach a particular amount?This can be calculated using the formula for calculating the future value (FV) as follows:
FV = PV(1 + r)^n ......................... (1)
Where:
FV = future value or the amount in the bank after certain years = 6500
PV = present value or the amount invested = 5000
r = quarterly interest rate = 6.25% / 4 = 0.0625 / 4 = 0.015625
n = number of quarters
Substituting relevant values into equation (1) and solve for n, we have:
6500 = 5000(1 + 0.015625)^n
6500 / 5000 = 1.015625^n
1.3 = 1.015625^n
Log linearize both sides, we have:
log1.3 = n * log1.015625
0.1139 = n0.0067
n = 0.1139 / 0.0067
n = 17 quarters
Number of years the money must be in the bank = n / number of quarters in a year = 17 / 4 = 4.25 years
To the nearest tenth of a year, we have:
Number of years the money must be in the bank = 4.3 years

find perimeter and area of composite figure
the perimeter of the composite figure is 20cm and its area is 37cm².
what is perimeter ?
Perimeter is the total length of the boundary of a two-dimensional shape or figure. In other words, it is the distance around the outside of a shape. To find the perimeter of a shape, you simply add up the lengths of all its sides.
In the given question,
To find the perimeter of the composite figure, we need to add up the lengths of all the sides.
Starting from the left side of the figure, we have a vertical line segment of length 6cm, followed by a horizontal line segment of length 5cm, then another vertical line segment of length 2cm, followed by a slanted line segment of length 3cm, then another horizontal line segment of length 2cm, and finally, a vertical line segment of length 2cm.
So the perimeter of the composite figure is:
Perimeter = 6cm + 5cm + 2cm + 3cm + 2cm + 2cm
Perimeter = 20cm
To find the area of the composite figure, we can break it down into simpler shapes and add up their areas.
The composite figure can be split into two rectangles, one with dimensions 6cm x 5cm and the other with dimensions 2cm x 2cm, and a right triangle with base 3cm and height 2cm.
The area of the first rectangle is:
Area = length x width
Area = 6cm x 5cm
Area = 30cm²
The area of the second rectangle is:
Area = length x width
Area = 2cm x 2cm
Area = 4cm²
The area of the right triangle is:
Area = (base x height) / 2
Area = (3cm x 2cm) / 2
Area = 3cm²
Therefore, the total area of the composite figure is:
Area = 30cm² + 4cm² + 3cm²
Area = 37cm²
So the perimeter of the composite figure is 20cm and its area is 37cm².

By solving a linear equation, we will see that the value of the greater integer is 12.
How to find the greater integer?Let's define x as the smaller integer, then the greater integer is:
x + 2
(is +2 because is the next consecutive even integer)
We know the sum of an integer and 4 times the next consecutive even integer is 58.
So we can write the linear equation:
x + 4*(x + 2) = 58
x + 4x + 8 = 58
5x = 58 - 8
5x = 50
x = 50/5
x = 10

Answer:
1) b = 17/4
2) x = -3/5
Step-by-step explanation (question one):
Step 1: Simplify both sides of the equation.
3b +9 + −5b + 3 = −14 +6b +−8
(3b +−5b) +(9 +3)=(6b) +(−14 + −8) (Combine Like Terms)
−2b +12 = 6b −22
Step 2: Subtract 6b from both sides.
−2b +12 −6b = 6b −22 −6b
−8b +12 = −22
Step 3: Subtract 12 from both sides.
−8b +12 −12 = −22 −12
−8b = −34
Step 4: Divide both sides by -8.
(-8b/-8) = (-34/-8)
Step 5: Get your Answer
b = 17/4
Step-by-step explanation (question two):
Step 1: Simplify both sides of the equation.
2x +5 + −4x +8 = (5)(5) +(5)(6x) + −12x (Distribute)
2x +5 + −4x +8 = 25 +30x + −12x
(2x+−4x) + (5+8) = (30x +−12x) +(25) (Combine Like Terms)
−2x +13 = 18x +25
Step 2: Subtract 18x from both sides.
−2x +13 −18x= 18x +25 −18x
−20x +13 = 25
Step 3: Subtract 13 from both sides.
−20x +13 −13 = 25 −13
−20x=12
Step 4: Divide both sides by -20.
(-20x/-20) = (12/-20)

Write the equation of a sine or cosine function to describe the graph.
Answer:
Step-by-step explanation:
first of all the graph is shifted up by 1 then we should add 1 to the function we have.
after that its obvious that the function is sine because if we remove the 1 we add it then it will be 0 when the angle is 0.
the function we have now is y = 1 + sin(ax).
to know the value of a we choose an angle we already know its sine for example:
2 = 1 + sin(a * 1/8)
1 = sin(a * 1/8)
sin-1(1) = PI/2 = a*1/8 => PI = 180
a = 4 * PI
at the end we will have => y = 1 + sin(4PI * x).
