Answer:

Step-by-step explanation:

adding both,

x-y=6 ------------------(1)

x+y=10 -------------------------(2)

Cutting y, we get

2x=16

∴x=8

Eq. in (2)

y=10-8

Softa [21]

Answer:

Let the no. Of members be x

Rs. 59.29 = 5929 paise

5929/x = x

x^2 = 5929

Therefore x = 77

No. Of members = 77

Hope this helps!

For the function shown below, find f(3): f(x)=2x^4-8x^2+5x-7

a_sh-v [17]

We have been given the function

$f(x)=2x^4-8x^2+5x-7$

We have to find the value of f(3). In order to find the same, substitute x=3 in the given function.

$f(3)=2(3)^4-8(3)^2+5(3)-7$

Now, we simplify this step by step.

First of all $3^4=81\text{ and }3^2=9$ . Thus, we have

$f(3)=2\times 81 -8\times 9+5(3)-7$

Now, we can easily simplify it by PEMDAS

$f(3)=162-72+15-7$

$f(3)=98$

Therefore, the value of f(3) is 98.

Two cards are drawn from a standard deck without replacement. What is the probability that the first card is a spade and the sec

Verizon [17]

Answer:

The answer is 0.123.

Step-by-step explanation:

You want to find the intersection between P(Spade) and P(Red). Knowing that there's no replacement, the probability will be given by the formula:

⇒ P(Spade∩Red) = P(Spade)*P(Red/Spade)

⇒ P(Spade∩Red) = P(Red)*P(Spade/Red)

Either formula works, but I'm going to choose to work with the first formula.

Therefore:

P(Spade) = $\frac{13}{52}$

P(Red/Spade) = $\frac{26}{52-1}$

So:

P(Spade∩Red) = $\frac{13}{52}$ * $\frac{26}{51}$ = $\frac{13}{102}$ = $0.123$
