Answer ALL if u cant see all the answers it don't matter all u need is the question

Which is an equation of a direct proportion?<br> y=16x+6<br><br> y=6x<br><br> y=6x−6<br><br> y=6x

natita [175]

The model for direct proportion is y = mx. Note that there is no "offset," no "y-intercept."

y = 6x represents direct proportion with a constant of proportionality 6. The other 2 choices are disqualified because of offset +6 or -6.

Makayla invested $630 in an account paying an interest rate of 5.5% compounded continuously. Assuming no deposits or withdrawals

ivolga24 [154]

Answer:

19.7 or 20 rounded

Step-by-step explanation:

A = $ 1,861.65

A = P + I where

P (principal) = $ 630.00

I (interest) = $ 1,231.65

Continuous Compounding Formulas (n → ∞)

Calculate Accrued Amount (Principal + Interest)

A = Pe^rt

Calculate Principal Amount, solve for P

P = A / e^rt

Calculate rate of interest in decimal, solve for r

r = ln(A/P) / t

Calculate rate of interest in percent

R = r * 100

Calculate time, solve for t

t = ln(A/P) / r

Each of these labelled bags contains two apples.

Dahasolnce [82]

Step-by-step explanation:

all bags are mislabeled. that means, whatever is written on either of the 3 bags, is wrong.

so, the bag labeled "green" is NOT the one with 2 green apples. the one labeled "red" is NOT the one with 2 red apples.

and - my favorite - the one labeled "red/green" is NOT the one with the mixture.

so, we pick one apple from the bag that is currently (mis-)labeled as "red/green".

as it cannot be the mixed bag, it must be one of the pure color bags.

whatever color shows up, we know this is the bag with 2 apples of that color.

then the bag that was labeled with that color must be the other pure color (if it were the mixed bag, it would mean that the third bag was labeled correctly, which is not the case). and then the third bag is the mixed one.

for example :

we get a red apple in our first pick.

so, the bag, that was originally (but wrongly) labeled as "red/green" gets the label "red".

then the bag with the original (but again wrong) label "green" gets now the label "red".

and the third bag with the original (but wrong) label "red" gets the "red/green" label.

if the first apple is green, then the same principle just with reversed colors applies.

Show that from any subset of 51 numbers taken from {1, 2, 3, ..., 100}, there exists a pair of elements such that one divides an

Sunny_sXe [5.5K]

Consider the 50 odd numbers 1,3, 5, ..., 99.

For each one, form a box containing the number and all powers of 2 times

the number.

So the first box contains {1,2,4,8, 16,..}

the next box contains {3,6,12,24,48, ...}

Then among the 51 numbers chosen, the pigeonhole principle tells us that there are two that are contained in the same box. They must be of the form $2^{m} k$ and $2^{n} k$ with the same odd number k. So one will divide the other.

<h3>What is pigeonhole principle?</h3>

According to the pigeonhole principle, if n items are placed in m containers, with n > m, at least one container must contain more than one item.

For example, if you have three gloves (and none of them are ambidextrous/reversible), you must have at least two right-handed gloves or at least two left-handed gloves, because there are three objects but only two categories of handedness to put them into.
