Mona always takes the same route when she walks her dog. First, she walks 5 blocks to the park. Then she walks 2 blocks to the elementary school. Finally, she walks 6 blocks to get back home. Mona walks her dog 4 times each day. How many blocks does Mona's dog walk each day?
Answers
Answer:
52 Blocks
Step-by-step explanation:
We need to find how many blocks Mona walks per day.
Info Given:
Number of blocks she walks in one walk.
Add the total blocks in one "route".
[tex]5 + 2 = 7\\7 + 6 = 13[/tex]
Mona walks 13 blocks in one route.
She walks her dog 4 times a day.
[tex]13 * 4 = 52[/tex]
Mona would walk her dog 52 blocks total per day.

A sample contains 10 pairs of values. Find the critical value for the linear correlation coefficient from Table A-6 corresponding to a 0.01 significance level.
a. 0.684
b. 0.632
c. 0.765
d. 0.798
Answers
The closest options provided are c. 0.765 or d. 0.798.
The question involves determining the critical value for the linear correlation coefficient for a sample with 10 pairs of values at a 0.01 significance level. Since the sample size is 10, the degrees of freedom (df) would be calculated as n - 2, which equals 8 (10 - 2 = 8). According to the provided studies and tables of critical values for determining the significance of a correlation coefficient, we reference a critical values table specific to our degrees of freedom and significance level.
At a 0.01 significance level and with 8 degrees of freedom, the corresponding critical value would typically be found in a statistical table designed for this purpose. However, based on the example given in the context, which is using a table with a standard significance level of α = 0.05, we can infer that the critical value for α = 0.01 would be higher, as the significance level is more stringent. None of the provided options (a. 0.684, b. 0.632, c. 0.765, d. 0.798) directly match the information given, but option c. 0.765 or d. 0.798 would typically be closer to a critical value at an α = 0.01 level with 8 degrees of freedom.

a shape is randomly selected from the following quadrilaterals: parallelogram, rhomus, trapaziod, rectangle, square. what is probability that it has 4 congruent sides
Answers
Answer:
Step-by-step explanation:
So, it's hard to know if the sides on the parallelogram are equal or not, but both a rhombus and square have four congruent sides, but only a square has four right angles.
So 1/2 shapes fit both parameters. Therefore there is a 50% probability it has four right angles, given that it has four congruent sides.
A window has an actual height of 4.5 feet. If a blue print has a scale of 3 inches = 2 feet. Find the height of the window in the blue print.
Answers
Answer:
The height of the window in blue print 6.75 inches.
Step-by-step explanation:
Given that, the actual length of the window is 4.5 feet.
If a blue print has a scale of 3 inches = 2 feet.
The actual length of an object is 2 feet then length of the object in blue print is 3 inches.
Then the actual length of an object is 1 feet then length of the object in blue print is (3÷2) inches =1.5 inches
The height of the window in blue print = (4.5×1.5)= 6.75 inches.
Answer:
6.75 inches

D.There are 0.75 deciliters in 7.5 liters.
Answers
Answer:
C.There are 6.8 kiloliters in 68 hectoliters.
Step-by-step explanation:
1 hectolitre = 100 litres
1 decilitre = 0.1 litre
1 kilolitre = 1000 litree
6.8 kilolitres = 6800 litres

Suppose that $17,183 is invested at an interest rate of 5.4% per year, compounded continuously. a) Find the exponential function that describes the amount in the account after time t, in years. b) What is the balance after 1 year? 2 years? 5 years? 10 years? c) What is the doubling time?
Answers
Answer:
Total = Principal * e ^ (rate * years)
Total = 17,183 * 2.718281828459 ^ (.054 * years)
After 1 year = 18,136.39
After 2 years = 19,142.68
After 5 years = 22,509.12
After 10 years = 29,486.15
We'll use this formula to find the doubling time:
Years = ln (total / principal) / rate
we'll use 200 for total and 100 for principal
Years = ln (200 / 100) / rate
Years = ln (2) / .054
Years = 0.69314718056 / .054
Years = 12.8360588993 Years Doubling Time
Step-by-step explanation:
The question is about continuous compound interest. An initial amount of $17,183 is invested with a 5.4% annual interest rate. An exponential function depicts the amount over time, you find the balance by substituting the values of time into the function, and the doubling time is calculated to be approximately 12.8 years.
Explanation:The subject matter of this question deals with the concept of continuous compound interest in Mathematics. No additional deposits are made, only the principal amount is growing over time at a continuous compound interest. The formula for the balance in a continuously compounding account is given by P(t) = P0*e^(rt), where P0=initial balance, r=annual interest rate (as a decimal), t=time in years, and e=approximately 2.71828. In this case, P0 = $17,183 and r = 5.4% = 0.054.
a) The exponential function that describes the amount in the account after time t is: P(t) = $17,183*e^(0.054t)
b) Using this function, you can substitute the values of t to find the balance after each year, for example, for 1 year, it's P(1) = $17,183*e^(0.054*1) and similarly for 2, 5, and 10 years.
c) Doubling time can be obtained by equating P(t) = 2 * P0, which can be solved to obtain t = ln(2) / r (natural logarithm of 2 divided by the annual interest rate). Hence, it would approximately be 12.8 years.

Answer:
[tex]1000\leq P\leq 15000[/tex].
Step-by-step explanation:
It is given that the population (P) varied from 1000 to 15000 in the rural towns.
We need to write an inequality which express the statement in symbols.
Variable P represents the population of rural towns.
Since population varied from 1000 to 15000, therefore the value of P must be greater than or equal to 1000 and less than or equal to 15000.
It can be written as
[tex]1000\leq P\leq 15000[/tex]
Therefore, the required inequality is [tex]1000\leq P\leq 15000[/tex].

The water level starts at 800. Then, with each year, we add a meter. It means that after t years we add exactly t meters.

Using these equations, determine and state the price of a drink, to the nearest cent.
Answers
Answer:
$7.25
Step-by-step explanation:
Let p=popcorn
Let d=drinks
25.75=1p+3d
81.25=4p+9d
p=4
d=7.25
Answer:
$7.25
Step-by-step explanation:
Cost of popcorn: x
Cost of drink: y
x + 3y = 25.75
x = 25.75 - 3y
4x + 9y = 81.25
4(25.75 - 3y) + 9y = 81.25
103 - 12y + 9y = 81.25
3y = 103 - 81.25
3y = 21.75
y = 7.25
x = 25.75 - 3(7.25)
x = 4
