Fine t12 term in an arithmetic progression having t3=10 and t10=-4

antiseptic1488 [7]

<h2>✏️ Development:</h2>

✍ Having as t₃ =10 and t₁₀ = -4. We have to find the common ratio.

❑ If, in front of the sequence from 3 to 10, there are 7 numbers, that is, 7 terms, we have to find a pattern, what I used was this one.

$\large {\text {$ \sf 7 \longrightarrow Number \: Terms $}}$

$\large {\text {$ \sf x \longrightarrow rasion $}}$

We see that in the calculation, the only number that fits is -2.

➤ Because if we stop to think about it, we have -2 of common ratio among these 7 terms is -14, so 10-14 = -4

So the hypothesis is correct!

➜ Being right as -2 and resuming the terms of 10, we have:

$\huge {\boxed {\blue {\sf t_{10}, t_{11}, {\bf t_{12}} = \{ -4 , -6 , \bf -8 \} } }}$

So t₁₂ is equal to -8.

A box of candy hearts contains 52 hearts, of which 19 are white, 10 are tan, 7 are pink, 3 are purple, 5 are yellow, 2 are orang

laiz [17]

<u>Answer-</u>

a. Probability that three of the candies are white = 0.29

b. Probability that three are white, 2 are tan, 1 is pink, 1 is yellow, and 2 are green = 0.006

<u>Solution-</u>

There are 19 white candies, out off which we have to choose 3.

The number of ways we can do the same process =

$\binom{19}{3} = \frac{19!}{3!16!} = 969$

As we have to draw total of 9 candies, after 3 white candies we left with 9-3 = 6, candies. And those 6 candies have to be selected from 52-19 = 33 candies, (as we are drawing candies other than white, so it is subtracted)

And this process can be done in,

$\binom{33}{6} = \frac{33!}{6!27!} =1107568$

So total number of selection = (969)×(1107568) = 1073233392

Drawing 9 candies out of 52 candies,

$\binom{52}{9} = \frac{52!}{9!43!} = 3679075400$

∴P(3 white candies) = $\frac{1073233392}{3679075400} =0.29$

Total number of ways of selecting 3 whites, 2 are tans, 1 is pink, 1 is yellow, and 2 are greens is,

$\binom{19}{3} \binom{10}{2} \binom{7}{1} \binom{5}{1} \binom{6}{2}$

$=(\frac{19!}{3!16!}) (\frac{10!}{2!8!}) (\frac{7!}{1!6}) (\frac{5!}{1!4!}) (\frac{6!}{2!4!})$

$=(969)(45)(7)(5)(15)=22892625$

Total number of selection = 3 whites + 2 are tans + 1 is pink + 1 is yellow + 2 greens = 9 candies out of 52 candies is,

$\binom{52}{9}=\frac{52!}{9!43!} =3679075400$

∴ P( 3 whites, 2 are tans, 1 is pink, 1 is yellow, 2 greens) =

$\frac{22892625}{3679075400} = 0.006$

Horse Of Course sells "Juan the horse" t-shirts for $23. Due to increased popularity, the store will raise the price by 8%. What

Sliva [168]

Answer:

the new price of the t-shirt is $24.84

Step-by-step explanation:

The computation of the new price of the t-shirt is shown below

= Price of the t-shirt × (1 + increased percentage)

= $23 × (1 + 0.08)

= $23 × 1.08

= $24.84

Hence, the new price of the t-shirt is $24.84

We simply applied the above formula so that the correct value could come

And, the same is to be considered
