Mary is walking 3 miles per hour jerry starts jogging at a rate of 4 miles per hour after marry has been walking for 15 minuets jerry jogs 2 miles as Mary continues walking and they both stop at the same time

Answers

Missing question: Determine the distanced covered by Mary.

Solution:
Mary: 3 mph
Jerry: 4 mph
Jerry starts jogging after Mary had been walking for 15 minutes.

Distance Mary had walked before Jerry starts jogging = Speed * Time = 3*15/60 = 0.75 miles.

Time taken by Jerry to jog for 2 miles = Distance/Speed = 2/4 =1/2 = 0.5 hrs.
Since they stopped at the same time,
Distance Mary walked while Jerry jogged = Speed* Time = 3*0.5 = 1.5 miles

Therefore,
Total distance Mary walked = 0.75+1.5 = 2.25 miles.

the probability of winning the game is 7/10. What is the probability that they will lose?

Answers

3/10 is the probability of them losing.

The probability of losing the game is 3/10 or 0.3 when the probability of winning is 7/10, because the total probability must always equal 1.

If the probability of winning the game is 7/10, then the probability of losing the game is the complement of the probability of winning. This means we subtract the probability of winning from 1. Therefore, the probability of losing the game is 1 - 7/10 = 3/10 or 0.3. This is because the sum of the probabilities of all possible outcomes in a probability distribution must equal 1.

If you buy a computer directly from the manufacturer for $ 2,469 and agree to repay it in 48 equal installments at 2.1 % interest per month on the unpaid balance, how much are your monthly payments? How much total interest will be paid?

Answers

Final answer:

The monthly payments would be approximately $61.02 and the total interest paid would be approximately -$764.04.

Explanation:

To calculate the monthly payments, you can use the formula for the monthly payment on a loan:

P = (r * PV) / (1 - (1 + r)^-n)

Where:

P is the monthly paymentr is the monthly interest ratePV is the present value or the loan amountn is the total number of payments

Using the given values, we can calculate:

P = (0.021 * 2469) / (1 - (1 + 0.021)^-48)

P ≈ $61.02

Therefore, the monthly payments would be approximately $61.02.

To calculate the total interest paid, you can multiply the monthly payment by the total number of payments and subtract the loan amount:

Total Interest = (P * n) - PV

Total Interest ≈ ($61.02 * 48) - $2469

Total Interest ≈ $1704.96 - $2469

Total Interest ≈ -$764.04

Therefore, the total interest paid would be approximately -$764.04. This negative value indicates that you will pay back less than the initial loan amount.

how do you do 27?????

Answers

Hey there!

To start, the equation needed to represent this problem would be an equation:
y= ab^x

a represents the initial amount. In this case, the initial amount would be 4 billion. It would be represented as 4 since each 1= one billion.

b represents the rate. Because the problem discusses a growth, convert the rate, 1.9% to a decimal and add 1 to it (add one if it is a growth, subtract one if it is a decay). b would be 1.019.

x represents the time in which the population grows or t.

When you piece this together, your equation should look like:
y=4(1.019)^t

or

Choice A.

Hope this helps and have a nice day! Feel free to ask any questions about my work. :)

The correct answer is: [A]: " P(t) = 4 * (1 .019)^t " .
_______________________________________________________
Explanation:
______________________________________________________
Use the formula for "exponential growth" :
______________________________________________________
→ " y = A * (1 + r)^t " ;
______________________________________________________
in which:
______________________________________________________
A = the "beginning population" ;

→ (in number representing "billions of people") ;

→ given the "beginning population" is "4 billion" ;

→ " A = 4 " ;
______________________________________________________
r = rate (of change) = 1.9% ; expressed as a decimal:

→ "r = rate = 1.9% = { 1.9 ÷ 100 } ;

→ {Take the "1.9" ; & move the decimal point 2 (two) spaces backward }:

→ 1.9% = 1.9 ÷ 100 = 0.019 ;

→ " r = 0.019 " ;

→ " t = time" ; (usually in "years" ; however, all the answer choices provided leave the "t" as it is; so we shall do so, too.
________________________________________________________

→ Replace "y" with: " P(t) " ;

→ And rewrite the equation of the function with our known values:

→ " y = A * (1 + r)^t " ;
____________________________________________________
→ becomes:

→ " P(t) = 4* (1 + 0.019)^t " ;

→ " P(t) = 4 * (1 .019)^t " ;
____________________________________________________
→ which is: Answer choice: [A]: " P(t) = 4 * (1 .019)^t " .

Karen is considering taking out a 20-year loan with monthly payments of $260 at an APR of 5.5%, compounded monthly, and this equates to a loan of $37,796.89. Assuming that the APR and the length of the loan remain fixed, which of these is a correct statement?

Answers

The correct statement is A;If Karen monthly payment $260 the amt of the loan that he is considering taking out would be less than $37,796.89

How to calculate EMI?

The EMI formula is :

[tex]\dfrac{pr(1 + r)^n}{(1 + r)^n - 1}[/tex]

Where r = 5.5/12/100 = 0.00425

p = 37,796.89

and n = 20 x 12 = 240

Putting the values in formula we get'

= (37,796.89x 0.00425 x 2.767)/1.767

= $350

Hence,

The correct statement is A; If Karen monthly payment $260 the amt of the loan that he is considering taking out would be less than $37,796.89

What is grater 9km or 145cm

Answers

First, you want to convert centimeters into kilometers to figure it out. 145cm = 0.00145 km. So then you need to compare 0.00145km to 9km. As you can see, 9km is greater. So your answer is 9km.

9km is greater than 145cm due to the conversion factor between kilometers and centimeters.

9km is greater than 145cm because when comparing the two, you need to ensure they are in the same unit. To compare, convert km to cm, 9km = 9,000,000cm. So, 9,000,000cm is greater than 145cm.

The vertex angle of an isosceles triangle is 20° less than the sum of the base angles. Which system of equations can be used to find the measure of the vertex and base angles?

A)
v + 2b = 180; 2b - 20 = v

B)
v + 2b = 180; 2b + 20 = v

C)
v - 2b = 180; v + 2b = -20

D)
v - 2b = 180; -2b - 20 = v

Answers

The answer to the above question can be explained as under -

We know that, the sum of angles of triangle is 180°.

So, vertex angle plus base angles are equal are equal to 180°.

Let the vertex angle be represented by "v" and base angles be represented by "b".

Thus, v + b + b = 180°

So, v + 2b = 180°

Next, the question says, the vertex angle is 20° less than the sum of base angles.

Thus, 2b - 20° = v

Thus, we can conclude that the correct option is A) v + 2b = 180°, 2b - 20° = v

The correct system of equations for an isosceles triangle where the vertex angle is 20 degrees less than the sum of the base angles is v + 2b = 180 for the sum of the angles, and 2b - 20 = v for the relationship between the base angles and the vertex angle. Option A is correct.

The correct system of equations to find the measure of the vertex and base angles of an isosceles triangle, where the vertex angle is 20° less than the sum of the base angles, is given by option A. The two equations can be described as follows:

The sum of the angles in a triangle is 180°, leading to the equation: v + 2b = 180.The vertex angle v is 20° less than the sum of the base angles, giving us the equation: 2b - 20 = v.

To solve for the angles, you would substitute the expression for v from the second equation into the first and then solve for b, which represents the measure of each base angle. Once you have b, you can find v by substituting b back into the second equation.

Find the Mean Median Mode and range of each data set that is obtained after adding the given constant. 12,10,15,17,15,9,10,15,12,14,+9. Please show work.

Answers

The given number arranged in order are:
9, 9, 10, 10, 12, 12, 14, 15, 15, 15, 17
1. To find the mean, add all the number together and divide the summation by 11[ which is the total number of the figures given]
Mean = [9 + 9 + 10 + 10 + 12 + 12 + 14+ 15 + 15 + 15 + 17] / 11 = 138 / 11
Mean = 12.5
Therefore, the mean is approximately equal to 13.

2. The median of a number refers to the number in the middle of a sorted set of number.
To find the median of a set of numbers, the numbers have to be arranged first in the correct increasing order and the number that falls in the middle will be the median. If two numbers fall in the middle, add the two together and find the average. For the set of number given above, the number that falls in the middle is 12.
Therefore, the median = 12.

3. The mode of a set of number refers to the number in the set, which has the highest frequency of occurrence, that is, it is the number that occur most. Looking at the set of number given above, 15 occurred three different times. Therefore, the mode of the set of number given above is 15.
