What are place values?

Place value describes the position or place of a digit in a number, which determines its numerical value.

Place values form the basis of the number system because the position occupied by a digit in a number shows its value.

The place values on the left of the decimal point include Billions, Hundred Millions, Ten Millions, Millions, Hundred Thousands, Ten Thousands, Thousands, Hundreds, Tens, and Ones.

After the decimal point, on the right, the place values include tenths, hundredths, and thousandths.

18 ones and 302 thousandths

= 1 ten + 8 ones + 3 tenths + 2 thousands

= (1 x 10) + (8 x 1) + (3 x 1/10) + (2 x 1/1,000)

Thus, 18 ones and 302 thousandths share the same place values as Options B and D.

Answers

The equation of line M that is parallel to line K is: x = -5.

What is the Equation of a Vertical Line?

A vertical line has a slope that is undefined. Therefore, it has no slope, hence, the equation of the line is expressed as x = b, where b is the point on the x-axis where the line intercepts.

Since line K and line M are parallel to each other, their slope will be the same. Line K has an undefined slope, so also will the slope of line M be undefined. This means line M is a vertical line.

Given that line M passes through (-5, 6), b = -5. To write the equation of the line M, substitute b = -5 into x = b:

How to determine the total number of coins?

From the question, we have the following parameters that can be used in our computation:

Number of coins in the box = 7

Proportion of coins in the box = 20%

These parameters mean that

Number of coins in the box = Proportion of coins in the box * Total number of coins

Substitute the known values in the above equation, so, we have the following representation

7 = 20% * Total number of coins

Divide both sides by 18%

Explain about the Interest?

In its most basic form, interest is computed as a percentage of the principle. The interest you would pay, for instance, would only be 5% of $100 if you borrowed $100 from a friend and agreed to reimburse it with 5% interest: $100(0.05) = $5.

An expense associated with borrowing money or other assets is interest. The principal, which represents the amount borrowed, is what's referred to as interest, which is calculated as a percentage of the principal over a specified period of time.

The interest rate for the loan is denoted by this proportion. When you place money in a high-yield savings account, for instance, a bank will give you interest.

= 11.5 x 1/100 = 0.155

= 0.155 ÷ 12 = 0.01291

= 1.29% Rate

John Rey invests $4100 in two different accounts. The first account paid 9 %, the second account paid 7 % in interest. At the end of the first year he had earned $307 in interest. How much was in each account?

Answers

John Rey invested $1000 in the first account at 9% interest and $3100 in the second account at 7% interest .

Let he invested x in the first account at 9%.

Interest = Principal × rate × time

Here rate = 0.09 and time = 1 year

Interest earned = 0.09x

Amount invested at 7% = $(4100-x)

rate = 0.07 and time = 1 year

Interest earned = 0.07(4100-x)

Total interest earned is $307

Hence : 0.09x + 287 - 0.07x = 307

or, 0.02x = 20

or, x = 1000

Amount invested at 7% = $(4100 - 1000) = $3100

Therefore John Rey invested $1000 in the first account at 9% interest and $3100 in the second account at 7% interest .

Calculating the amount of interest that will be owed on a sum of money at a certain rate and for a specific period of time is possible using simple interest.

Simple interest does not change the principal amount in the same way as compound interest, which adds the interest of one year's principal to the next year's principal to calculate interest.

Answers

The 0.39 dollar would have to present in order to obtain a probability of 0.500.

What is the sample space for a random experiment?

Sample space is the set of all possible outcome the considered random experiment can result to.

Thus, suppose we toss a coin, then tossing a coin is a random experiment, and the sample space is {'head', 'tail'}. We ignore other outcomes like slant coin, or standing coin by assuming that coin is very thin to stand and always falls down.

Using the sample size relation with the standard normal distribution, the required sample size is 64  samples.

σ = $80 and n = 64

n = [(Z × σ) / ME]²

ME = margin of error

Z = 0.500

Now Substituting the values into the equation :

n = [(Z × σ) / ME]²

n = [(0.500 × 80 ) / 64]²

n = (40/ 64)²

n = 0.625²

n = 0.39

Therefore, the 0.39 dollar would have to present in order to obtain a probability of 0.500.

Now, the slope is calculated as,

=> m = (13 - 8) / (314 - 249)

=> m = 5 / 65

=> m = 1/13

Now, the intercept is calculated as,

The average speed 70 miles/hour, Dee needs to cover the remaining distance in 6 hours.

What is speed?

In unit time, the distance covered by any object is called speed.

In mathematical term, Speed is express as S=D/T,

where S=speed, D=distance, T= time.

Given that,

Total distance of trip = 1020 miles

Average speed of Lila = 68 mph

And time taken by Lila for driving = 5 hours

Distance covered by Lila = 68×5 = 340 miles

Average speed of Mary - 65 mph

And time taken by Mary for driving = 4 hours

Distance covered by Mary = 65×4 = 260 miles

Distance covered by Lila and Mary = 340+260 = 600

Remaining distance = 1020-600 = 420

Dee covers 420 miles distance in 6 hours,
