Answer:
87.5
Step-by-step explanation:
Let the missing side be x.
28 / 35 = x / 50
4 / 7 = x / 50
4 ( x ) = 7 ( 50 )
4x = 350
x = 350 / 4
x = 87.5

What happens to the width of a confidence interval for a population mean if the level of confidence is increased without changing the sample size? Assume that the population standard deviation is unknown and the population distribution is approximately normal. Select your answer from the choices below.
Answer:
The increase in the level of confidence means that the interval will be wider.
Step-by-step explanation:
Margin of error of a confidence interval:
The margin of error of a confidence interval has the following format:
\(M = z\frac{s}{\sqrt{n}}\)
In which z is related to the confidence level(if the confidence level increases z increases), s is related to the standard deviation and n is the sample size.
The higher the margin of error, the wider the interval is.
In this question:
Increasing the level of confidence will mean an increase in z, and thus, since M and z are directly proportional, the margin of error will increase, and the inteval will be wider.

Calculate the distance between the points (4,-2) and (7,-9)
The Distance between the points (4, -2) and (7, -9) is sqrt(58) or approximately 7.62 units.
The distance between two points in a coordinate plane. The distance formula is based on the Pythagorean theorem and calculates the straight-line distance between two points.
The coordinates of the first point as (x1, y1) = (4, -2) and the coordinates of the second point as (x2, y2) = (7, -9).
The distance formula is given by:
d = sqrt((x2 - x1)^2 + (y2 - y1)^2)
Plugging in the values:
d = sqrt((7 - 4)^2 + (-9 - (-2))^2)
d = sqrt((3)^2 + (-7)^2)
d = sqrt(9 + 49)
d = sqrt(58)
Hence, the distance between the points (4, -2) and (7, -9) is sqrt(58) or approximately 7.62 units.

16 families went on a trip which cost them Rs 2,16,352. How much did each
family pay?
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.
to know more about unitary method
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
A ball is shot from a cannon into the air with an upward velocity of 40 ft/sec. The equation that give the height (h) of the ball at any time (t) is: h(t)= -16t^2 + 40t + 1.5. Find the maximum height attained by the ball. I need a clear explanation because I have to expose this
The height of the ball at any time t is given by
\(h(t)=-16t^2+40t+1.5\)This is a quadratic equation, which attains its maximum value at time:
\(t=\frac{-b}{2a}\)In the given equation, a = -16 and b = 40. substitute these values in the formula:
\(t=\frac{-40}{-16\times2}=\frac{-40}{-32}=\frac{5}{4}\)Therefore, the ball attains its maximum height at t=5/4 seconds which is given below:
\(\begin{gathered} h(\frac{5}{4})=-16(\frac{5}{4})^2+40(\frac{5}{4})+1.5 \\ =-25+50+1.5 \\ =26.5 \end{gathered}\)Thus, the maximum height attained by the ball is 26.5 feet.

Denise bikes 3 miles to her friend's house, and then she bikes home. The average rate biking to her friend's house is twice the average rate coming home. Write and simplify an expression for the time it takes Denise to make a round-trip in terms of the average rate coming home x.
Hint : Use d = rt.
The total time for the trip is:
T = 3mi*( 3/2x).
Where x is the rate at which she comes home.
How to find the time for the total trip?
Remember the relation:
distance = rate*time.
We know that the distance is 3 miles (done twice).
First, the rate is 2x and then the rate is x, then the time it took the first half is:
t = 3mi/2x
And for the coming back:
t = 3mi/x
Then the total time for the trip is:
T = 3mi/2x + 3mi/x = 3mi( 1/2x + 1/x) = 3mi*( 3/2x).

Suppose that $500 is deposited into an account that pays 5.5% interest compounded
quarterly. How long will it take for the account to contain at least $1400? Round to the
nearest whole number.
Answer:
18.85 years
Step-by-step explanation:
Using the \(A=P(1+\frac{r}{n} )^{nt}\) we can manipulate it to give us time.
However, let's identify our variables:
A is our final amount which is given to us, $1400.
P is our principle which is $500.
r is our rate which is 5.5% which can be traducted into 0.055.
n is the # of time our money get compounded per year, in this case quarterly means 4 times a year therefore n = 4.
t is time and is what we are trying to solve for.
Now let's manipulate our equation to find t:
\(A=P(1+\frac{r}{n} )^{nt}\)
\(\frac{A}{P} =(1+\frac{r}{n} )^{nt}\)
\(\frac{1400}{500} =(1+\frac{0.055}{4} )^{4t}\)
\(2.8=1.01375^{4t}\)
\(log_{1.01375}(2.8)=log_{1.01375}1.01375^{4t}\)
\(log_{1.01375}(2.8)=4t\)
\(\frac{log_{1.01375}(2.8)}{4} =t\)
\(18.84876253=t\)
It would take about 18.85 years in order for you to accumulate at least $1400.

find the bearing of a from b
find the bearing of b from a
Answer:
130° and 310°
Step-by-step explanation:
the bearing of A from B is the measure of the clockwise angle from a north line at B to A
the angle at B and A are same- side interior angles and sum to 180°
angle at B = 180° - 50° = 130°
the bearing of A from B is then 130°
the bearing of B from A is the measure of the clockwise angle from the north line at A to B
the complete angle about A = 360° then clockwise angle from north line at A to B is
360° - 50° = 310°
the bearing of B from A is 310°

find the exact value of x. 45 degree and 10 side
Answer:
The exact value of the other leg is 10.
Step-by-step explanation:
Finding the exact value of x given a 45 degree angle and a side length of 10 can be done using trigonometry. In a 45-45-90 right triangle, the two legs are congruent and the hypotenuse is equal to the square root of 2 times the length of the legs.
Therefore, if one leg is 10, the hypotenuse is 10 times the square root of 2. To find the length of the other leg, we can use the Pythagorean theorem:
c^2 = a^2 + b^2, where c is the hypotenuse, a and b are the legs of the right triangle.
Substituting known values, we get:
(10√2)^2 = 10^2 + b^2
200 = 100 + b^2
b^2 = 100
b = 10
Therefore, the exact value of the other leg is 10.
Mario kept all of his movie and popcorn receipts for an entire year. The movie tickets were $12.00 each and all together he spent $325.60. There were only seven visits that he did not buy popcorn. He has a total of 39 receipts. How much did each bag of popcorn cost?
Answer:
$3.10
Explanation:
• For each visit ,(except 7),, he paid for both popcorn and the movie.
,• He has a total of 39 receipts.
Therefore, the number of popcorns that he bought will be:
\(\begin{gathered} Number\; of\; popcorns=\frac{39-7}{2}=\frac{32}{2}=16\text{ popcorns} \\ \implies Number\; of\; movies=39-16=23\text{ movies} \end{gathered}\)Since the movie tickets were $12.00 each, the amount spent on movies will be:
\(Movie\; Expense=23\times\$12=\$276\)We then use this to determine the amount spent on popcorns.
\(\begin{gathered} \text{Amount spent on popcorn}=Total-\text{Amount spent on movies} \\ =325.60-276 \\ =\$49.60 \end{gathered}\)Recall that we earlier stated that Mario bought 16 bags of popcorn.
Therefore, the cost of a bag of popcorn will be:
\(\frac{49.60}{16}=\$3.10\)Each bag of popcorn costs $3.10.Each bag of popcorn costs

3 6 9 12 15 18 21 24 27 30 is odd or even numbers?
Answer: Half of them are even and half of them are odd.
Step-by-step explanation:
The even numbers are 6, 12, 18, 24, and 30. An even number is defined as a number that is divisible by 2, meaning it has no remainder when divided by 2. For example, 6 divided by 2 equals 3 with no remainder, so 6 is even.
The odd numbers are 3, 9, 15, 21, and 27. An odd number is defined as a number that is not divisible by 2, meaning it has a remainder of 1 when divided by 2. For example, 9 divided by 2 equals 4 with a remainder of 1, so 9 is odd.
Therefore, out of the given numbers, half of them are even and half of them are odd.
