Answer:
Given:
Two angles of a triangle are of measures 53 & 44.
We need to find the measure of the unknown angle.
According to the angle sum property, Sum of all angles of a triangle is 180°
Thus, 44°+53°+m∠1=180°
⇒ 97 + m∠1 = 180°
⇒ m∠1 = 180° - 97°
⇒ m∠1 = 83°
Therefore (B) 83 is the correct answer

A) find the vertical intercept of the graph and explain what information it gives about the situation
B) find the slope of the graph and explain what information it gives about the situation
A) For the y-intercept. The cost of the rental fee at 0hour is $100.
B) The rate of the price of the hall with respect to the time is 66.7 dollars/hour
The y-intercept of the graph is the point where the line cuts the y axis. From the graph, we can see that the line cuts the y-axis at y = 100
This means that the cost of rental fee at 0 hour is $100.
To get the slope of the graph, we will use the coordinate point (0,100) and (3,300)
\(Slope =\frac{300-100}{3-0}\\Slope = \frac{200}{3}\\Slope = 66.7\)
This shows that the rate of price of the hall with respect to the time is 66.7 dollars/hour

A spinner with repeated colors numbered from 1 to 8 is shown. Sections 1 and 8 are purple. Sections 2 and 3 are yellow. Sections 4, 5, and 6 are blue. Section 7 is orange.
Which statement about probability is true?
The probability of landing on orange is greater than the probability of landing on purple.
The probability of landing on yellow is less than the probability of landing on blue.
The probability of landing on orange is equal to the probability of landing on yellow.
The probability of landing on purple is equal to the probability of landing on blue.
The statement about probability that is correct would be that the probability of landing on yellow is less than the probability of landing on blue. That is option B.
What is probability?Probability is defined as the total number of possible outcome of an event.
The repeated colour which are numbered from 1 to 8 are as follows:
Sections 1 and 8 are purple. The probability of getting a purple = 2/8 = 1/4Sections 2 and 3 are yellow. The probability of getting a yellow = 2/8 = 1/4 Sections 4, 5, and 6 are blue. The probability of getting a blue = 3/8Section 7 is orange.

Seve & Exit
Su
Navern's manufacturing cycle efficiency (MCE) for its elevators is: 41.4%
How to solve the manufacturing cycle efficiencyThe formula for obtaining the manufacturing cycle efficiency is value-added time divided by the production cycle time * 100. In the data given, the process and inspection times qualify as a value-added time
Process time = 23 days
Inspection time = 13 days
Value added time = 23 + 13 = 36days
The production cycle time = Move time + process time + queue time + inspection time + wait time
= 22 + 12 + 23 + 13 + 17 days

On this problem, the answer has been worked out, but you must fill in the blanks in the solution.A random sample of 450 students from a wide geographical area indicated that 55 attended private schools. Estimate the true proportion of students attending private schools with 95% confidence. Give your answer to three places after the decimal point.Solution: We need to find the 95% confidence interval for the proportion (p).
State the parameters given in the question
\(n=450\)The sample size n is 450
Hence, the first box n=450
\(X=55\)The number of students X that attended private school is 55
Hence, the second box X=55
Therefore, sample proportion is
\(\begin{gathered} ^{\prime}p=\frac{X}{n}=\frac{55}{450} \\ ^{\prime}p=0.122 \end{gathered}\)Hence, the third box is 'p=0.122
\(\begin{gathered} ^{\prime}q=1-^{\prime}p \\ ^{\prime}q=1-0.122 \\ ^{\prime}q=0.878 \end{gathered}\)Hence, the forth box is 'q= 0.878
From the question, the confidence interval is 95% can be represented as
\(\begin{gathered} z_{\alpha I2}=95\text{ \%=0.95} \\ \alpha=1-0.95=0.05 \\ \alpha I2=\frac{0.05}{2}=0.025 \end{gathered}\)The Z score for confidence interval of 95% is gotten from the table as 1.96
The formula for the confidence interval for p is
\(^{\prime}p-z_{\alpha I2}\sqrt[]{\frac{^{\prime}p^{\prime}q}{n}}Substitute into the formula
\(\begin{gathered} ^{\prime}p-z_{\alpha I2}z_{\alpha I2}\sqrt[]{\frac{^{\prime}p^{\prime}q}{n}} \\ ^{\prime}p=0.122;^{\prime}q=0.878;z_{\alpha I2}=1.96 \\ =0.122-1.96_{}\sqrt[]{\frac{0.122\times0.878}{450}} \\ =0.122-1.96\sqrt[]{\frac{0.107116}{450}} \\ =0.122-1.96\sqrt[]{0.0002380356} \\ =0.122-1.966(0.015428) \\ =0.122-0.03024 \\ =0.09176 \\ =0.092(3\text{ decimal places)} \end{gathered}\)\(\begin{gathered} z_{\alpha I2}\sqrt[]{\frac{^{\prime}p^{\prime}q}{n}}\text{was calculated to be 0.03024} \\ \text{Therefore} \\ ^{\prime}p+z_{\alpha I2}\sqrt[]{\frac{^{\prime}p^{\prime}q}{n}}=0.122+0.03024=0.15224 \\ =0.152(3\text{decimal places)} \end{gathered}\)Hence, the confidence interval is 0.092

Mrs. Smith made 6 ¼ dozen cookies for the birthday party. At the end of the party, there were 3 ½ dozen cookies left. How many cookies did the guests eat?
The guests in the birthday party ate 33 cookies.
How many cookies did the guests eat?We know that Mrs. Smith made 6 1/4 dozen cookies and there were 3 1/2 dozen cookies left.
Let's first convert these fractions to a common denominator of 4, so we can easily subtract them.
6 1/4 dozen = 25/4 dozen
3 1/2 dozen = 14/4 dozen
Now we can subtract the number of cookies that were left from the number of cookies that were made:
25/4 - 14/4 = 11/4 dozen
To find out how many cookies this represents, we need to multiply by the number of cookies in one dozen.
There are 12 cookies in one dozen, so:
11/4 x 12 = 33
Therefore, the guests ate 33 cookies.

The equation C=24n+2 represents the cost
Jim did not buy any tickets (n_Jim = 0).
Larry bought 7 more tickets than Jim.
To determine the number of tickets Larry bought more than Jim, we need to find the values of n for Larry and Jim's ticket purchases.
For Larry:
Let's substitute C = $170 into the equation C = 24n + 2 and solve for n:
$170 = 24n + 2
Subtracting 2 from both sides:
$168 = 24n
Dividing both sides by 24:
n = 7
For Jim:
We can calculate the number of tickets Jim bought by subtracting 12 from Larry's number of tickets:
n_Jim = n_Larry - 12
n_Jim = 7 - 12
n_Jim = -5
Since we cannot have a negative number of tickets, we can conclude that Jim did not buy any tickets (n_Jim = 0).
To find the difference in the number of tickets bought, we subtract the number of tickets Jim bought from the number of tickets Larry bought:
n_difference = n_Larry - n_Jim
n_difference = 7 - 0
n_difference = 7
Therefore, Larry bought 7 more tickets than Jim.

Given that 16 families went on a trip and the cost of the trip was Rs. 2,16,352.The amount paid by each family is to be determined by unitary method Hence each family paid Rs.13522
Now, let's solve this by using the method of unitary method. To find the cost of 1 family trip, we will divide the total cost of the trip by the number of families.2,16,352 / 16 = 13,522 So, the cost of the trip per family is Rs. 13,522.Hence, each family paid Rs. 13,522 for the trip.

https://brainly.com/question/28276953
Answer:
Step-by-step explanation
1. The total cost of the trip for all 16 families is Rs 2,16,352.
2. To find out how much each family paid, we need to divide the total cost by the number of families: Rs 2,16,352 ÷ 16.
3. When we do the division, we get the result: Rs 13,522.
Now let's check if this result is correct:
1. If each family paid Rs 13,522 for the trip, then the total cost for all 16 families would be: 16 × Rs 13,522 = Rs 2,16,352.
2. This is exactly the same as the total cost given in the problem statement.
So we have shown that each family paid **Rs 13,522** for the trip

Simultaneously, the horizontal asymptote at y=0 serves as a reassuring indication that the cost of producing pills cannot be negative, as it steadfastly remains at or above zero.
