There are seven boys and five girls in a class. The teacher randomly selects three different students to answer questions. The first student is a boy, the second student is a girl, and the third student is also a girl.
7/66, 5/39, 2/9, 1/32

Answers

Answer 1

Answer:

7/66

Step-by-step explanation:

The probability of picking one girl would be 5/12 That is because there are 5 girls out of the 12 students, and the probability of an event occuring is:

of things you want/of things are possible

Using that same logic, the next student should be easier. We reduced the student population by 1, so we have 11 possible ways it can happen now instead of 12, so that gives us 7/11 for the probability of picking a boy as the second pick.

And lastly, using the same logic shown above, the probability of picking a girl on the third pick would be: 4/10

We are not done, though. We have the separate probabilities, but now we have to multiply then together to figure out the probability of this exact event happening:

5/12 * 7/11 * 4/10 = 140/1320

Which when reduced is: 7/66

Answer 2

7/66 HOPE THIS HELPS

Answer:

From Least to Greatest :

-20 3/4

-15 1/2

-14 3/4

-1/4

Step-by-step explanation:

We have four fractions those of which are negative, meaning this question works a bit differently than how most least to greatest questions would work by. When dealing with negatives, you have to go backwards, or in other words, the highest number would be the least and the lowest number would be the greatest. This is due to the negative rule, that it's sort of like fighting to zero first than instead of fighting to a great and huge number. With this information, we can answer our question.

-20 3/4 is the highest number, but since we are dealing with negatives it is more far from zero, therefore making the least greatest.

Following up with -15 1/2 , its closer but not as close to the other two numbers.

Now with -14 3/4, getting closer, but not close enough as :

-1/4. This is the closest to zero, therefore it is the greatest number out of the three.

You now have your order.

B.

C.

D.

Answers

Question: What is 35 percent of 40?

Percentage solution with steps:

Step 1: Our output value is 40.

Step 2: We represent the unknown value with $x$x.

Step 3: From step 1 above,$40=100\%$40=100%.

Step 4: Similarly, $x=35\%$x=35%.

Step 5: This results in a pair of simple equations:

$40=100\%(1)$40=100%(1).

$x=35\%(2)$x=35%(2).

Step 6: By dividing equation 1 by equation 2 and noting that both the RHS (right hand side) of both
equations have the same unit (%); we have

$\frac{40}{x}=\frac{100\%}{35\%}$
40
x=
100%
35%

Step 7: Again, the reciprocal of both sides gives

$\frac{x}{40}=\frac{35}{100}$
x
40=
35
100

$\Rightarrow x=14$⇒x=14

Therefore, $35\%$35% of $40$40 is $14$ B. 14%

What are some examples of recursion in real life, such as things you can write a recursive equation for? (for example, fern leaves are an example of a geometric sequence, and the distance from the ground on stairs is an example of an arithmetic sequence)

Answers

Answer: In programming terms, recursion happens when a function calls itself. If you have a problem that is too complex, you can use recursion to break it down into simpler blocks. You do this in real life all the time. Imagine you have a whole box full of $100 bills and you need to count how much money you have.

Andre rode his bike at a constant speed. He rode 2 1/3 miles in 11 2/3 minutes.

(a) Write an equation that represents the distance d he rides (in miles) after time t (in minutes) passes.
(b) How long will it take Andre to ride 4 2/5 miles?

Answers

Given that Andre rode his bike at a constant speed.
Number of miles driven = 1 mile
Time taken to drive 1 mile = 5 minutes.
Then speed can be calculated using formula:
Speed = Distance / Time

Now we have to find the amount of time t (in minutes) taken by him to right distance d so we can again use same formula.

Speed = Distance / Time
or
Time = Distance / Speed
Plug the given values

t = 5d
