Answers

Answer 1

Answer:

Mean:

Median:

Mode:

35, 44, 77, 68, 43, 55, 2

Answer 2

Answer:

Answer:

There's no mode. The median is 44. The mean is 50.

Step-by-step explanation: Mean is 35+44+77+68+43+55+28=350/7=50 You divide by 7 because there are 7 numbers. Median is the middle number. There are no repeated numbers so there's no mode.

Please answer the question from the attachment.

Answers

A.) A = P (1 + r)^t

P = 500 ; r = 3% ; t = 2

A = 500 (1 + 0.03)²
A = 500 (1.03)²
A = 500 * 1.0609 numerical expression
A = 530.45

A numerical expression is an expression that involves purely numbers and one or more operational symbols.

B) compound interest for 2 years.

530.45 - 500 = 30.45 is the compound interest for 2 years.

HELP MEEE!!!!!How do I use the distributive property to remove the parentheses?

-3 ( - 3 v + 4 y - 2 )

Answers

-3 (-3v + 4y -2)
-3*-3v = 9v
-3*4y = -12y
-3*-2 = 6

9v - 12y + 6 is the final answer. :)

You multiply the number on the outside to the numbers inside the parentheses.
9v-12y+6

Solve the system of equations.

Answer:

y= - 271/71

x=755/71

z =4866/71

Step-by-step explanation:

For resolve a system you multiply an equation of the system or add two of the equation and replace the result in the system

Add the 1st and 2nd, and replace the 2nd

4x + 3y + z= -6 4x + 3y + z= -6 4x + 3y + z= -6

(-4) (x-3y + 2z=0) → -4x +12y -8z =0 → +15y -7z = -6

11x-2y + 3z = - 26 11x-2y + 3z = - 26 11x-2y + 3z = - 26

Add the 2nd and 1st, and replace the 1st

4x + 3y + z= -6 4x + 3y + z= -6 4x + z= -6

(-1/5)( 15y -7z = -6) → -3y -7/5z =6/5 → -3y -7/5z =6/5

11x-2y + 3z = - 26 11x-2y + 3z = - 26 11x-2y + 3z = - 26

Add the1st and 3rd, and replace the 3erd

(-3)( 4x + z= -6) -12x - 3z= 18 -12x - 3z= 18

-3y -7/5z =6/5 → -3y -7/5z =6/5 → -3y -7/5z =6/5

11x-2y + 3z = - 26 11x-2y + 3z = - 26 -x-2y = - 8

Add the1st and 3rd, and replace the 1st

(1/3)(-12x - 3z= 18 ) -4x - z= 6 -4x - z= 6

(5)(-3y -7/5z =6/5) → -15y - 7z = 6 → -15y - 7z = 6

-x-2y = - 8 (-4)(-x-2y = - 8) 4x + 8y= 32

Add the 1st and 2nd, and replace the 2nd

(-7)(8y - z =38) -56y +7z= 266 -56y +7z= 266

-15y - 7z = 6 → -15y - 7z = 6 → -71y=271 → y= - 271/71

(1/4)(4x + 8y= 12) x+2y=3 x+2y=3

-56y +7z= 266 → -8y + z =38 → z =4866/71

x+2y=3 → x=755/71

On Monday it snowed nine inches. The next day it snowed one-half that amount. How much did it snow on the Second day?

Answers

Well half of 9 inches is 4.5, so 4.5 inches?

9 ÷ 2 = 4.5

On the second day it snowed 4.5 inches.

Disjunction is OR, written like a right side up ∨. The upside down V is conjunction, AND, written ∧.

Let's make the disjunction truth table.

A or B is true when either A is true or B is true or both. It's false when they're both false. That's called inclusive OR.

Answer: C

Interestingly, in the original algebra created by Boole, he preferred exclusive OR, written A^B. A^B is false when both A and B are true, but otherwise like inclusive OR. When we do it this way, exclusive OR is like addition mod 2 and AND is multiplication mod 2, so the algebra of Boole was more like regular algebra than what we call Boolean algebra today.

I agree with c and you are very smart to think c I agree
