Step-by-step explanation:

Using a proportion:

5.5 liters * 1,000 milliliters/liter = 5,500 milliliters

Conversion method:

1 liter = 1,000 milliliters

So, 5.5 liters = 5.5 liters * 1,000 milliliters/liter = 5,500 milliliters

The point estimate from a confidence interval can be found by taking the midpoint of the interval.

The formula for the point estimate is (lower bound + upper bound) / 2. For example, the 95% confidence interval for a sample mean of 25 is (23, 27). The point estimate for this sample mean is (23 + 27) / 2 = 25. This point estimate is the best estimate of the true population mean.

In essence, the point estimate is the best guess of the population mean given the data. It is calculated by taking the midpoint of the confidence interval, which is the range of values that is believed to contain the population mean with a certain degree of confidence. The point estimate is usually the most reliable estimate and is used to make decisions in statistical analysis.

The total amount with Siobhan is given by the equation S = $ 8.33

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the amount with Siobhan be represented as S

Let the amount with Priya be represented as P

Let the amount with James be J = $ 7.00

And , Priya makes 40% more than James

So , P = ( 40 / 100 ) x P + P

Substituting the values in the equation , we get

The amount with P = ( 0.40 ) ( 7 ) + 7

The amount with Priya P = 2.8 + 7

The amount with Priya P = $ 9.80

Now ,

Siobhan makes 15% less than Priya

So , the amount with Siobhan S = P - ( 15/100 )P

Substituting the values in the equation , we get

The amount with Siobhan S = 9.80 - ( 0.15 )( 9.80 )

On simplifying the equation , we get

The amount with Siobhan S = 9.80 - 1.47

The amount with Siobhan S = $ 8.33

2 and 3 has a multiplicative inverse of -3 and 2, which is 2. A number that, when multiplied by the inputted number, produces the result 1 is said to be the multiplicative inverse of that number.

When a number is multiplied by another, the result is 1, this is known as the multiplicative inverse of the original number . It is the reciprocal of a number per multiplicative inverse definition. A-1 or is used to denote the multiplicative inverse of a number "a".

According to the multiplicative inverse property, a multiplies with its reciprocal, 1/a, to get 1, for any number a. It follows that 1/a is a number's multiplicative inverse. The multiplicative inverse of 5, when applied to the integer 5, is 1/5, according to this characteristic. Dividing 1 by a real number yields the multiplicative inverse of that number. One fifth (1/5, or 0.2) and one-quarter (0.25, or 1 divided by 0.25, respectively) are examples of reciprocals.

The equation of the line that passes through the points (36,-30) and (-12,34) is  y = - 4 / 3 x + 18.

The equation of a line can be represented in slope intercept form as follows:

y = mx + b

where

Therefore, let's find the equation of the line  that passes through the points (36, -30) and (-12, 34).

Hence, the slope can be found as follow:

slope = y₂ - y₁ / x₂ - x₁

slope = 34 + 30 / -12 - 36

slope = 64 / -48

slope = - 8 / 6 = - 4 / 3

Therefore, let's find the y-intercept of the line using (-12, 34)

y = - 4 / 3 x + b

34 = - 4 / 3 (-12) + b

34 = 16 + b

b = 34 - 16

If tangent of x degrees equals four-thirds, and measures of triangle is 10. 5 units, and NM measures 2b units then the value of b is equals to seven. So, last option is correct, b = 7 here.

Right angled triangle : A triangle is defined as a regular polygon, with three sides and the sum of any two sides is always greater than the third side. Right angled triangle is one type of triangle. When the angle between a pair of sides is equal to 90 degrees it is called a right-angle triangle. See in above figure ∆LMN is a right angled triangle with m∠LMN = 90° . Also, we have m∠MLN = x° so, m∠LNM = 180° - 90° - x° = 90° - x° ( Since, sum of interior angles of triangle = 180°)

Length of side LM = 10.5

length of side, NM = 2b

tangent of x, tan x = 4/3

We have to determine the value of b. For considering angle x° as centre point then

base of triangle = LM = 10.5

As we know Tangent of any angle is equals to ratio of perpendicular/base.

so, tan x = 4/3 = LM/NM

=> 4/3 = 2b / 10.5

=> 4× 10.5 = 2b × 3

=> b = 42.0/6

Adrian need to invest $2041.88,  to the nearest hundred dollars for the value of the account to reach $3900 in 14 years.

Let principal amount is x

And interest is y

Then, according to question

X + y = 3900    --------------eq(1)

and formula of interest

I = (P*t*R)/ 100

Y = (x * 14 * 6.5) / 100   ----------------------eq(2)

3900 – x = (x * 14 * 6.5) / 100  from eq(1) and eq(2)

390000 – 100x = 91x

191x = 390000

X = 2041.88

So, therefore principal amount = $2041.88

and interest = $1858.12

You can earn interest on interest by using compound interest. Compound interest is interest that is earned on both the initial principal and interest that builds up over time in a savings account.

You get interest based on the amount you deposit when you add money to a savings account or other account of a similar nature. For instance, if you deposit $1,000 in an account that offers 1% yearly interest, after a year you would have received $10 in interest.

There may be a difference in the timing of when interest is paid out and compounded. For instance, interest on a savings account may be paid monthly but compounded daily. The account balance plus any interest that has accrued but has not yet been paid out are used by the bank to determine your daily interest earnings.
