Okay, so it starts off with 7 less, so we know that there's a negative 7. All that's left is the product of 5 and a NUMBER. Instead of saying number, we could put a variable, such as x. Now, we'd get a product of 5 and x minus 7. Now, product means multiplication, so you'd multiply 5 and a number(x) which would end up giving you 5x minus 7. Now add subtraction and you get;

5x-7

37th term; a1 = 2.3; d = -2.3

Sindrei [870]

<u>Answer:</u>

37th term of given arithmetic sequence $a_1$ = 2.3; d = -2.3 is -80.5.

<u>Solution:</u>

Given that

Need to determine 37th term, when $a_1$ = 2.3, d = -2.3

Means first term of arithmetic sequence = $a_1$ = 2.3 and common difference d = -2.3

<u><em>Formula for nth term of arithmetic sequence is </em></u>

$\mathrm{a}_{\mathrm{n}}=\mathrm{a}_{1}+(\mathrm{n}-1) \mathrm{d}$ --- equation 1

$\text { In our case } a_{1}=2.3, d=-2.3$

We need to determine 37th term so n = 37.

On substituting given values in equation (1) we get

$\mathrm{a}_{37}=\mathrm{a}_{1}+(37-1) \mathrm{d}$

$\begin{array}{l}{\Rightarrow a_{37}=2.3+(37-1)(-2.3)} \\\\ {\Rightarrow a_{37}=2.3(1-36)=2.3 \times 35=-80.5}\end{array}$

Hence 37th term of given arithmetic sequence is -80.5

Suppose that you and a friend are playing cards and decide to make a bet. If you draw two red cards in succession from a standar

N76 [4]

Answer:

E=$19.307

Step-by-step explanation:

Total number of cards = 52

If you win then you will get $50

If you lose then you will give him $20

Therefore the probability

$P(first\ card\ is\ face\ card)=\dfrac{12}{52}$

$P(Second\ card\ is\ face\ card)=\dfrac{11}{51}$

$P(Third\ card\ is\ face\ card)=\dfrac{10}{50}$

Thus the probability for all the three cards are face card

$P=\dfrac{12}{52}\times \dfrac{11}{51}\times \dfrac{10}{50}$

P=0.0099

Thus the probability for all the three cards are not face card

P=1-0.0099=0.9901

P=0.9901

Therefore , expected value

$E=20\times 0.9901-50\times 0.0099$

E=$19.307

Therefore the answer will be $19.307.
