Answer:
L1 = L2 = 16.5 cm and L3 = 7cm
Step-by-step explanation:
Triangle perimeter = L1 + L2 + L3 = 40 cm
L1 = L2 = L
L3 = 7
Then:
40 = 2L +7
33 = 2L
L = 33/2
L = 16.5 cm

The margin of error for this confidence interval is 0.145.
Given :
a confidence interval for a proportion ranges from 0.45 to 0.74.
Confidence interval :
A confidence interval, in statistics, refers to the probability that a population parameter will fall between a set of values for a certain proportion of times
Margin of error :
Margin of error, also called confidence interval, tells you how much you can expect your survey results to reflect the views from the overall population.
Length of confidence interval = 0.74 - 0.45
= 0.29
we know that,
Margin of error = 1/2 * length of confidence interval.

You decide to invest $500 into a 4-year CD that pays 2.85% interest
compounded monthly.
Use the compound interest formula:A = P(1 + r/n) ^nt to give:
a. The future value in 4 years.
b. The interest gained in 4 years.
Future value in four years is $1060.30 and Interest gained in four years is 560.30.
Define compound interest.Compound interest is interest that builds up over a set length of time on both principal and interest. The principal is also used to account for the interest that has accrued on a principal over time. Furthermore, the accumulated principal value is used to calculate interest for the subsequent time period. The new way of calculating interest now utilized in all international financial and commercial operations is known as compound interest. When we look at the compound interest values that have built over successive time periods, the power of compounding is clearly apparent.
Given
You decide to invest $500 into a 4-year CD that pays 2.85% interest compounded monthly
Compound interest
A = P( 1+ r/n)^nt
Interest gained in 4 years
A = 500( 1+ 0.0285/12)^(12)(4)
A = 500( 1 + 0.002375) ^48
A = 560.30
Future value in 4 years = $500 + $560.30
Future value in 4 years = $1060.30
Future value in four years is $1060.30 and Interest gained in four years is 560.30.

Two trains leave stations 480 miles apart at the same time and travel toward each other. One train travels at 90 miles per hour while the other travels at 110 miles per hour. How long will it take for the two trains to meet?
It will take 2 hours 24 minutes time to two trains to meet.
Let a train starts from A towards to B with velocity v1 = 90 miles/hour
and another train starts it's journey from B towars A with velocity v2 = 110 miles/hour
Let after time t hour they meet at C.
Hence, we get AC + CB = AB
⇒ v1t + v2t = 480
⇒ (v1 + v2) t = 480
⇒ (90 + 110) t = 480
⇒ t = 480/200 = 48/20 = 12/5 hours
∴ t = [tex]2\frac{2}{5}[/tex] hours
= 2 hour (2/5 × 60) mins

if q is an odd number and the median of q consecutive integers is 120, what is the largest of these integers?
If q is an odd number and the median of q consecutive integers is 120, then the largest of these integers is option (A) (q-1) / 2 + 120
The number q is an odd number
The median of q consecutive integers = 120
Consider the q = 3
Then three consecutive integers will be 119, 120, 121
The largest number = 121
Substitute the value of q in each options
Option A
(q-1) / 2 + 120
Substitute the value of q
(3-1)/2 + 120
Subtract the terms

Answer:

The equivalent ratio of yellow cars to purple cars in the form n:1 is 1.54:1.
What is Ratio?A ratio is a mathematical comparison between two or more quantities or values. It expresses the relative sizes or amounts of different quantities and is typically represented in the form of a fraction or a colon (:).
The greatest common divisor (GCD) of 97 and 63 is 1, which means they have no common factors other than 1.
Therefore, we can write the ratio of yellow cars to purple cars as: 97:63
Since we need to write it in the form of n:1, we can divide both sides of the ratio by 63 (the smaller number in the ratio):
= 97/63 : 63/63
= 97/63 : 1
= 1.54 : 1
So, the equivalent ratio of yellow cars to purple cars in the form n:1 is 1.54:1.

Patrick borrows $1400 from a bank with 10% simple interest each year. How much will patrick need to pay back in total in 2 years?.
Amount Patrick has to pay back is $ 1680 and the simple interest is $ 280.
What is Simple Interest?
Simple interest is a method of calculating interest that ignores the impact of compounding. While interest frequently compounds throughout the course of a loan's set periods, simple interest does not. Simple interest is calculated by multiplying the principal amount by the interest rate, times the number of periods.
Simple Interest = ( Principal Amount x Rate x Time Period ) 100
Given data ,
Let the principal amount be = A
The value of A = $ 1400
Let the rate of interest be = r
The value of r = 10 %
Let the number of years = T
The value of T = 2 years
Now , the simple interest is calculated by the formula
Simple Interest = ( Principal Amount x Rate x Time Period ) 100
Substituting the values in the equation , we get
Simple Interest = ( 1400 x 10 x 2 ) / 100
Simple Interest = 14 x 20
Simple Interest = $ 280
Therefore , the simple interest in 2 years is $ 280
And , the total amount Patrick has to give back to the bank is given by the formula
Amount in 2 years = Principal + Interest
Amount in 2 years = 1400 + 280
Amount in 2 years = $ 1680
Therefore , the amount in 2 years is $ 1680
Hence , Amount Patrick has to pay back is $ 1680 and the simple interest is $ 280

A Formula for the Surface area of the cube is 6a².
A cube is a three-dimensional solid with six square faces, facets, or sides, three of which meet at each vertex in geometry. It looks like a hexagon from the corner, and its net usually looks like a cross. One of the five Platonic solids, the cube is the only regular hexahedron.
The sum of the areas on each face of the cube that covers it is the cube's surface area. The formula for surface area is six times the cube's length divided by the square of that number. It is denoted by 6a², where a is the cube's side length. It basically refers to the entire surface area.
area of one face = a² [By area of square formula]

A quadratic equation is a second-order polynomial equation in a single variable x ax²+bx+c=0. with a ≠ 0. Because it is a second-order polynomial equation, the fundamental theorem of algebra guarantees that it has at least one solution. The solution may be real or complex.
Let's suppose the age of Nachelle is 'x' years then Julian's age would be 'x+2'.
x² + [2(x + 2)]² = 139
x² + 4x² + 8x + 16 = 139

A cylindrical vase with a curved surface area of 6.79 square metres will cost Rs. 8.14 to paint.
What is curved surface area?The area with just curved surfaces, leaving the circular top and base, is referred to as the curved surface area. Curved surface area is the amount of space left over after subtracting the cylinder's total circular area. The formula for curved surface area is 2 * pi * r * h.
Here,
We have to calculate the curved surface area of glass in which the flower basket is placed.
Glass is cylindrical,
Height of cylinder = 180cm = 1.8m
Radius of cylinder = 60cm = 0.6m
The curved surface area of the cylinder = 2πrh
The curved surface area of the cylinder = 2*22/7*0.6*1.8
The curved surface area of the cylinder = 6.78584 m²
Cost of painting the glass per m² = Rs. 1.2
Cost of painting 6.78584= 6.78584*1.2
