Find 3/5 x 4/7 in simplest form
Answer:
3/5 * 4/7 = 12/35
you can find the answer by multiplying the numerator by the other numerator and the denominator by the other denominator
[tex]\frac{3}{5} \times \frac{4}{7}[/tex] in its simplest form is [tex]\frac{12}{35}[/tex]
To evaluate the given multiplication in its simplest form, we will find the product of the given two fractions.
First, let us write the given fractions properly
That is,
[tex]\frac{3}{5} \times \frac{4}{7}[/tex]
Now, we will carry out the multiplication operation
[tex]\frac{3}{5} \times \frac{4}{7} = \frac{3 \times 4}{5 \times 7}[/tex]
Then, we get
[tex]\frac{3}{5} \times \frac{4}{7} = \frac{12}{35}[/tex]
(NOTE: This is the simplest form as both the numerator and the denominator do not have a common factor)
Hence, [tex]\frac{3}{5} \times \frac{4}{7}[/tex] in its simplest form is [tex]\frac{12}{35}[/tex]

Answer:
48
Step-by-step explanation:
To solve this we need to do the operations in the brackets first. We should start with the innermost brackets. Then, we work our way outwards. To show my working out I will use an asterisk (*) for multiplication to not confuse X as a variable.
8*{[(7 + 4) * 2] - [(11 - 7) * 4]}
= 8*{[(11) X 2] - [(4) X 4]}
= 8*{[22] - [16]}
= 8*{6}
= 48
After your yearly checkup, the doctor has some bad news and some good news. The bad news is that you tested positive for a serious disease, and the test is 99% accurate( i.e. that probability of testing positive given that you have the disease is .99, as is the probability of testing negative given that you don’t have the disease). The good news is that this is a rare disease, striking only one in 10,000 people. What are the changes that you actually have the disease?
Answer:
0.009804
Step-by-step explanation:
We are given;
probability of testing positive given that you have the disease is 0.99
Also, probability of not testing positive and not having the disease is 0.99
We are also told that it is a rare disease and so strikes only 1 in 1000 people = 0.0001
Let's denote positive test by T+, negative test by T¯, having the disease by D+, not having the disease by D¯.
So, we can now denote all the values in probability we have written earlier.
Thus:
P(T+ | D+) = 0.99
P(T¯ | D¯) = 0.99
P(D+) = 0.0001
Thus, P(D¯) = 1 - P(D+) = 1 - 0.0001 = 0.9999
Now, let's find probability of testing positive;
P(T+) = (P(T+ | D+) × P(D+)) + (P(T+ | D¯) × P(D¯))
Now, (P(T+ | D¯) is not given but by inspection, we can infer from the values given that it is 0.01
Thus;
P(T+) = (0.99 × 0.0001) + (0.01 × 0.9999)
P(T+) = 0.010098
Chances that one has the disease would be gotten from Baye's theorem;
P(D+ | T+) = (P(T+ | D+) × P(D+))/P(T+) = (0.99 × 0.0001)/0.010098 = 0.009804
What are the correct intermediate steps of the following data set when it is being sorted with the bubble sort? 15, 20, 10, 18
A. 15,10,20,18 -- 15,10,18,20 -- 10,15,18,20
B. 10, 20,15,18 -- 10,15,20,18 -- 10,15,18,20
C. 15,20,10,18 -- 15,10,20,18 -- 10,15,20,18 -- 10,15,18,20
D. 15,18,10,20 -- 10,18,15,20 -- 10,15,18,20 -- 10,15,18,20
Answer:
A. 15,10,20,18 -- 15,10,18,20 -- 10,15,18,20
Step-by-step explanation:
Bubble sorting can be defined as a technique or methodology whereby numbers that are not in their proper order are sorted into proper order that is from smallest to highest( increasing to decreasing order).
The method of bubble sorting involves the shuffling or swapping of adjacent numbers until the numbers are well sorted or arranged.
In the above question, we were given, a set of numbers:
15, 20, 10, 18
Step 1
20 is adjacent to 10
20 > 10
hence we swap
= 15,10,20,18
Step 2
From, 15,10, 20,18
20 is adjacent to 18
20 > 18
hence we swap
= 15,10,18,20
Step 3
From step 2, which gave us 15,10,18,20
15 us adjacent to 10
15 > 10
We swap
= 10,15,18,20
Hence,
15, 20, 10, 18 -- 15,10,20,18 -- 15,10,18,20 -- 10,15,18,20
Therefore, Option A is the correct option.
The correct intermediate steps of data 15, 20, 10, 18 set when it is being sorted with the bubble sort is; Choice A: 15,10,20,18 -- 15,10,18,20 -- 10,15,18,20.
Definition;
Bubble sort, otherwise termed the sinking sort, is a simple sorting algorithm that repeatedly steps through the list, compares adjacent elements and swaps them if they are in the wrong order.
With emphasis on the word adjacent, it is evident Choice A is the correct intermediate steps of the data set 15, 20, 10, 18 when it is being sorted with the bubble sort.

It’s an undefined term
It consist one endpoint
You used to points to name it
It consist of all points in between the two points
Answer:
It goes in one direction and indefinitely.
It consist one endpoint.
Step-by-step explanation:
A ray is a straight line that emerges out of a start point and moves in a direction. The line begins with the start point and moves in one direction. The start point and the other side are named with capital letters. It is denoted by writing the two letters and placing an arrow above the letters. There is no endpoint in a ray.

What is the value of y?
Answer:
26
Step-by-step explanation:
We know that the entire angle measures 66 degrees.
Therefore, angle y plus 40 degrees must equal 66.
In an equation:
[tex]y+40=66[/tex]
To solve for y, subtract 40 from both sides:
[tex]y=26\textdegree[/tex]
So, the measure of angle y is 26 degrees.
And we're done!
Answer:
26°
Step-by-step explanation:
The angle with 66° which is shown with a red line is the sum of y and 40° so to find the value of y
we subtract 40 from 66 which gives us result as 26°.

suryana bought 16 watches for rs 16000. At what rate should he sell the watches to gain rs 3200?
Answer:
Step-by-step explanation:
So if 16 watches is 16000 rs, then if you want to make 3200 more rs, your total from 16 watches should be 19200 (which is 16000+3200)
so the rate per watch should be 19200/16 = 1200
So it should be 1200rs/watch is the rate
Answer:
So if 16 watches is 16000 rs, then if you want to make 3200 more rs, your total from 16 watches should be 19200 (which is 16000+3200)
so the rate per watch should be 19200/16 = 1200
So it should be 1200rs/watch is the rate

Angle 1 and Angle 2 are complementary. The measure of Angle 1 is 21
more than twice the measure of Angle 2. Find the measure of Angle 1
Since both angles are complementary, then Angle 1 + Angle 2 = 90°
Using algebra,
let Angle 2 be X and Angle 1 be (2X + 21°)
Now we have an equation of,
( 2X + 21 ) + X = 90°
step 1 : open up the brackets first.
step 2 : bring 21° to the other side (rmb to flip the sign)
step 3 : bring the 3 over n it becomes " ÷3 "
( 2X + 21° ) + X = 90°
2X + 21° + X = 90°
3X = 90° - 21°
X = ( 90° - 21° ) ÷ 3
= 23°
Sub X=23° into Angle 1 ( 2X + 21° ),
2(23°) + 21° = 67°
Therefore,
Angle 1 = 67°

This question is about how transformations can affect graphs.

So we can reflect the function over the y-axis and then compress it by a factor of 4 to make the graph [tex]x^2[/tex].
Then we can move the graph over to the left 3 because the c value is positive, meaning that we move the graph over to the left.
Finally, we can move the function of by [tex]\frac{2}{3}[/tex] because the d value is positive, meaning that we move the graph up.

Los números reales están representados por números racionales e irracionales.
Un número racional es un número real que se puede formar dividiendo dos números enteros (un número entero es un número sin parte fraccionaria). La palabra viene de "ratio".
Un número irracional es un número real que NO se puede hacer dividiendo dos números enteros (un número entero no tiene parte fraccionaria). "Irracional" significa "sin relación", por lo que no es un número racional.
