The distance between Reeta's house and her office is 14 km. She covers 10 km 65 m by scooter, 3 km 75 m by bus and the rest on foot. How much distance does she cover by walking?
Answer:
She covered 0.86 km or 860m by walking.
Step-by-step explanation:
Given:
➮ Distance between Reeta's house and her office is 14km.
She covers 10km 65m by Scooter. Then, 3km 75m by Bus. And rest of distance covered by foot.To Find:
➮ How much distance covered by foot/walking ?
Solution:
To find the distance covered by foot = Total distance - Sum of distance covered through scooter and bus.
Sum of distance covered through scooter and bus:-
As, we know:
• 1km = 1000m
⇒ 10km = 10×1000
= 10000m
⇒ 3km = 3×1000
= 3000m
So, 10000m + 65m ➝ 10065m
3000 + 75m ➝ 3075m
➝ 10065m + 3075m
➝ 13140m
• 13140m into km:-
⇒ 13.14km
Now, Finding the distance covered by walking:
➝ 14km - 13.14km
➝ 0.86km
Hence, She covered 0.86km or 860m by walking.

The distribution of the animals in the coral reef is an illustration of probability
The most likely animalThe distribution of the animals is given as:
Blue fish = 3
Yellow fish = 7
Sea turtle = 1
Eels = 3
The animal with the highest frequency is the most likely animal.
Hence, the Yellow fish is the most likely animal.
Which is more likely?From the question, we have:
Blue fish = 3
Eels = 3
Both animals have the same frequency.
This means that Riley has equal chance of seeing a blue fish and an eel.
The probability of seeing an animal with fins
The animal with fins are:
Blue fish = 3
Yellow fish = 7
So, the probability is:
[tex]p = \frac{3 + 7}{3 + 7 + 1 + 3}[/tex]
[tex]p = \frac{10}{14}[/tex]
Simplify
[tex]p = \frac 57[/tex]
Hence, the probability of seeing an animal with fins is 5/7
The least likely animalThe animal with the least frequency is:
Sea turtle = 1
So, the likelihood is:
[tex]p = \frac 1{14}[/tex]
Hence, the sea turtle has the least likelihood of 1/14
Animals with equal likelihoodThe Blue fish and the Eels have the same frequency of 3
This means that animals have equal likelihood
The probability of seeing each animal
We have:
Blue fish = 3
Yellow fish = 7
Sea turtle = 1
Eels = 3
Express as probability
Blue fish = 3/14
Yellow fish = 7/14
Sea turtle = 1/14
Eels = 3/14
Express the fractions as decimals
Blue fish = 0.214
Yellow fish = 0.500
Sea turtle = 0.071
Eels = 0.214
So, their likelihoods are:
Blue fish = Equally likely
Yellow fish = Certainly likely
Sea turtle = Unlikely
Eels = Equally likely

Nancy started the year with $425 in the bank and is saving $25 each week. Sam started the year with $705 but is spending $15 a week. When will Nancy and Sam have the same amount of money? How much money will they each have? Write a system of equations that model the following situation. Define each variables with a “Let” statement, write two equations, and solve completely.
Answer:
The system of equations:
Nancy: Y=$425+$25x
Sam : Y=$705-$15x
Given:
Amount in Nancy's bank = $425
Amount saved by Nancy each week = $25
Amount in Sam's bank = $705

Based on the relationship between intercepted arc and inscribed angle, the value represented by x is: D. 140°.
What is the Relationship Between Measure of Inscribed Angle and Intercepted Arc?The intercepted arc = twice the inscribed angle.
Thus:
Intercepted arc = x
Inscribed angle = m∠CEB = 180 - 110 = 70°

find the value of x y and z in the rhombus below
Answer:
Step-by-step explanation:
In Rhombus opposite angles are equal.
6x + 8 = 86
6x = 86 - 8 {Subtract 8 from both sides}
6x = 78
x = 78/6 {Divide both sides by 6}
x = 13
In rhombus adjacent angles are supplementary.
7y + 3 + 86 = 180
7y + 89 = 180
7y = 180 - 89 {Subtract 89 form both sides}
7y = 91
y = 91/7 {Divide both sides by 7}
y = 13
5z + 4 + 86 = 180
5z + 90 = 180
5z = 180 - 90 {Subtract 90 from both sides}
5z = 90
z = 90/5 {divide both sides by 5}
z = 18

The probability a car salesman sells a car to a customer is 0.05
Assuming the salesmen sees 16 customers in a week, what is the probability he sells less than 3 cars?
Write answer using three decimal places
Using the binomial distribution, it is found that there is a 0.957 = 95.7% probability that he sells less than 3 cars.
What is the binomial distribution formula?The formula is:
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
The parameters are:
x is the number of successes.n is the number of trials.p is the probability of a success on a single trial.In this problem:
The probability a car salesman sells a car to a customer is 0.05, hence p = 0.05.The salesmen sees 16 customers in a week, hence n = 16.The probability he sells less than 3 cars is:
P(X < 3) = P(X = 0) + P(X = 1) + P(X = 2).
In which:
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]P(X = 0) = C_{16,0}.(0.05)^{0}.(0.95)^{16} = 0.4401[/tex]
[tex]P(X = 1) = C_{16,1}.(0.05)^{1}.(0.95)^{15} = 0.3706[/tex]
[tex]P(X = 2) = C_{16,2}.(0.05)^{2}.(0.95)^{14} = 0.1463[/tex]
Then:
P(X < 3) = P(X = 0) + P(X = 1) + P(X = 2) = 0.4401 + 0.3706 + 0.1463 = 0.957.
0.957 = 95.7% probability that he sells less than 3 cars.

Given two similar triangles, what would you need to know
to find an unknown length? How would you find that
unknown length?
Answer:
There is a pattern with the ratios of corresponding sides. You can see that the measurement of each side of the first triangle divided by two is the measure of the corresponding side of the second triangle. Use patterns like this to problem solve the length of missing sides of similar triangles.
Answer:
I would need to know the length of a pair of corresponding sides, so I could set up a proportion to solve for the unknown length. I would set the ratio of the known corresponding sides equal to the unknown measure, making sure I put corresponding measures from the triangles in the same positions in the ratios. Then I would cross-multiply to solve.

Models are equations, tables and graphs that are used to represent functions.
How to interpret a modelThe question is incomplete as the models are not given, so I will give a general explanation
For two models to be the same, the equations of the model must be the equivalent.
Take for instance, the following models are the same

Find the slope and the y-intercept of the line.
3x+5y=−4
Write your answers in simplest form.
Answer:
slope = -3/5
y intercept = 4/5
Step-by-step explanation:
First, we can rearrange 3x + 5y = 4 into slope intercept form (y = mx + b) to get 5y = -3x + 4. Now we can divide by 5 to make y the subject: y = -3/5x + 4/5. The number in front of x is the slope and the number on its own is the y intercept.
slope = -3/5
y intercept = 4/5

are there in the glass of water? Write your answer in scientific notation
Answer:
8.25*10^24
Step-by-step explanation:
1000*.25= 250 (this converts the .25 into milliliters)
250(3.3 * 10^22)
= 8.25*10^24
The required molecules of water in the glass are given as 8.25 × 10²⁴.
What is a unit of measurement?Unit of measurement is defined as every entity having its measures in dimensions, weight, and time. Such as for length we have a meter, for liquid we have liters, and so on.
Here,
A glass of water contains 0.25 liter of water.
1 liter = 1000 mililiters
So,
0.25 liter = 250 mililiter
Now,
1 milliliter of water contains 3.3 x 10²² water molecules,
Number of molecules in 0.25 liters of water,
= 250 × 3.3 x 10²²
= 8.25 × 10²⁴
Thus, the required molecules of water in the glass are given as 8.25 × 10²⁴.
