Answer:

$\frac{16}{27}$

Step-by-step explanation:

From the table, we notice that the total number of students is:

$3+10+8+6=27$

Then, along the second column of the table, we notice that the number of students who do not have a brother is:

$10+6=16$

So, the probability that a randomly chosen student does not have a brother is:

$\frac{\text{number of students who do not have a brother}}{\text{total number of students}}=\frac{16}{27}$

16 over 27 sorry if i’m wrong.

Delancey plans to run at least three miles each week for her health. Delancey has a circular route in the neighborhood to run. Once around that route is 220 yd. If Delancey runs that route 40 times during the week, will she cover at least 3 mi explain

Answers

Answer: Yes

Step-by-step explanation:

Since she wants to run the route 40 times we have to multiply the 220 yd route with how many times she wants to run it

40 x 220 = 8800 which is 5 miles

She reaches her goal and beyond that

Yes, because if you multiply 220 by 40, you will get 8,800, which is 5 miles.

The length of line segment AD is 6.8 cm. The length of line segment AB is 3 cm. The length of line segment BC is 1.6 cm. Find the length of line segment CD.

Answers

Answer:

9.6

Step-by-step explanation:

This is a four side figure which is most likely to be a trapezium.So AD is the hypotenuse,AB is side (a),BC is the height and CD is side (b).

The length of line segment AD is 6.8 cm. The length of line segment AB is 3 cm. The length of line segment

Proof that the formula Fn = Fn-1 + Fn-2 works
Fibonacci python

Answers

Umm— fn-1+Fn-2?? Fibonacci python

= f6 .

IV. The sum of the first n Fibonacci numbers with even indices is

f2 + f4 + ... + f2n = f2n+1 - 1.

Proof:

From II,

f1 + f2 + f3 + ... + f2n = f2n+2 - 1.

When we subtract the result from III, we get the desired result.

Example:

f2 + f4 + f6 + f8 + f10 + f12 = 1 +3 + 8 + 21 +55 +144

= 232

= f13 - 1 .

V. The sum of all (fn+1)/ (fn )

converges to the Golden Ratio.

3/1 + 5/3 + 8/5 + 13/8 .... converges to ) / 2.

Proof that Rn converges to the Golden Ratio:

Let R = lim Rn as n approaches infinity

= lim f n+1 / f n as n approaches infinity

= lim fn + fn-1 /fn as n approaches infinity

= lim (1 + fn-1/ fn) as n approaches infinity

= 1 + lim (fn-1 /fn ) as n approaches infinity

= 1 + 1/ lim (fn-1 /fn ) as n approaches infinity

= 1 + 1/R

So, R = 1 + 1/R,

or R^2 = R + 1,

R^2 - R - 1 = 0,

R = ( ) / 2

= ( ) / 2

Since Rn is positive, Rn = ( ) / 2 .

Thus, Rn converges to the Golden Ratio.

(REPLY FOR EXTRA POINTS) School hack:
If you have a question something like this: "Determine which integer makes the inequality 6(n − 5) < 3(n + 4) true."
The answer would most likely be the last answer choice.
This is because when teachers create the question they put it as the last one to make you work out all of the firsts ones first so you can do more work which means more practice.
I'm not 100% sure, but I had a question like this and the answer was the last one.
Hope this school hack helps!! :)

Keira said that if 6 tickets are sold, there should be 2 tickets left. Is Keira correct?

Answers

To determine whether Keira's statement is correct, we need to analyze the information provided.

According to Keira, if 6 tickets are sold, there should be 2 tickets left. However, we don't have any information about the initial number of tickets available.

If the total number of tickets initially was 8, and 6 tickets were sold, then there would indeed be 2 tickets left, supporting Keira's statement.

However, if the total number of tickets initially was less than 8, or if the statement doesn't specify the initial number of tickets, we cannot determine if Keira's statement is correct.

Therefore, without additional information, we cannot determine the accuracy of Keira's statement.

in order to know if Keira has two tickets left, we need to know the first number of tickets without that number there is no way to find the remainder

Player B is the most consistent, with a range of 10.
Player A is the most consistent, with an IQR of 1.5.
Player A is the most consistent, with a range of 5.

Answers

Answer: Player B is the most consistent, with an IQR of 3.5.

Step-by-step explanation:

For Player A, the IQR is 2 (Q3 - Q1 = 3 - 1 = 2).

For Player B, the IQR is 3.5 (Q3 - Q1 = 5 - 1.5 = 3.5).

Therefore, Player B is more consistent, as their IQR is larger, indicating less variability in their scores.

Maria has already written Two-fifths of her 1,000 word essay. If she continues writing at the same pace of 6One-half words per minute, which expression shows the amount of time it will take her to write the rest of the essay?

Answers

Answer: B

Step-by-step explanation: Well use the process of elimination, there are no three-fifths in the equation so you can exclude options C and D, and then you take the remaining words left (600) and divide it by 6 and 1/2 to get how much time left. you wouldn't multiply it because that would increase the time which doesn't make sense.

Answer:

A,B,D

Step-by-step explanation:

A: 4-10=-6. -6=-n 6=n (negatives cancel)

B: 3*2=6 n=6

D: 48/8=6 n=6

∑ Hey, js1012201 ⊃

Answer:

(A) 4 = 10 - n

(B) 3 = n/2

(D) 8n = 48

Step-by-step explanation:

Given:

Select all the equations where n = 6 is a solution.

Choose 3 answers:
(A) 4 = 10 - n

(B) 3 = n/2

(C) 12 = n + 7

(D) 8n = 48

(E) 5 + n = 8

Solution:

Let's solve each answer choices to see where n = 6 is a solution:

-------------------------------------------------------------------------------------------------------------

(A) 4 = 10 - n

4 + n = 10 - n + n

4 + n = 10

4 + n -4 = 10 - 4

n = 6

(A) n = 6

-------------------------------------------------------------------------------------------------------------

(B) 3 = n/2

Multiply both sides by 2

2n/2 = 3 × 2

n = 6

(B) n = 6

-------------------------------------------------------------------------------------------------------------

(C) 12 = n + 7

Subtract both sides by 7

n + 7 -7 = 12 - 7

n = 5

(C) n = 5

-------------------------------------------------------------------------------------------------------------

(D) 8n = 48

Divide both sides by 8

8n/8 = 48/8

n = 6

(D) n = 6

-------------------------------------------------------------------------------------------------------------

(E) 5 + n = 8

Subtract 5 from both sides

5 - 5 + n = 8 - 5

n = 3

(E) n = 3

ivan and jeff buy a package of 8 pen for 4.00. ivan want 5 of the pen. how many should ivan pay?

Answers

Answer:

$2.50

Step-by-step explanation:

Let's set up a proportion using the following setup.

price / pens = price / pens

We know that it costs $4.00 for 8 pens.

$4.00 / 8 pens = price / pens

We don't know how much it costs for 5 pens. Therefore, we can say it costs $x for 5 pens.

$4.00 / 8 pens = $x / 5 pens

4/8=x/5

We want to solve for x (the cost for 5 pens). Therefore, we must get x by itself on one side of the equation. x is being divided by 5. The inverse of division is multiplication, so multiply both sides of the equation by 5.

5*(4/8)=(x/5)*5

5*(4/8)=x

5*0.5=x

2.5=x

x= $2.50

Ivan should pay $2.50 for 5 pens.

Jane interpreted the mean of the given data set, 7.96 , as meaning half the cats weighed less than 7.96 pounds and half weighed more. What was Jane's error? Explain.

Answers

Answer:

Jane's error was that she assumed that the mean of the data set would represent a midpoint, where half of the cats weighed more and half weighed less.

What informs the assertion?

This is not necessarily the case, as the mean is only an average of the data set and does not necessarily represent any particular point within the data set. For example, if the data set was composed of 8 cats that all weighed 8.48 pounds, then the mean would be 8.48, but none of the cats would weigh less than 8.48 pounds.

Area is the inside of the picture so that is also out

It is either primeter or volume

Volume is used to find the surface of an object, it takes up. It is used for 3-d objects, since this is not a 3-d piece it is not that.

Answers

Answer:

Step-by-step explanation:

We can solve for H by isolating it on one side of the equation, as follows:

J/H - I/H = G

Taking H as the common denominator:

(J - I)/H = G

Multiplying both sides by H:

J - I = GH

Adding I to both sides:

J = GH + I

Dividing both sides by G:

H = (J - I)/G

So the answer is

(A)

H = (J - I)/G.

Answer: A

Step-by-step explanation:

$\frac{J}{H} = G + \frac{I}{H}$ >Since you are solving for H bring I/H to the other side

by subtracting I/H from both sides

$\frac{J}{H}- \frac{I}{H} = G$ >There is a common denominator so you can

combine the fractions

$\frac{J-I}{H} = G$ >Multiply both sides by H or cross multiply whichever

way your mind things about how to get H on top

$J-I = G(H)$ >Divide both sides by G

$\frac{J-I}{G} = H$ >Answer is A
