Answer 1

Answer:

The weights of 1,000 men in a certain town follow a normal distribution with a mean of 150 pounds and a standard deviation of 15 pounds. From the data, we can conclude that the number of men weighing more than 165 pounds is beyond the mean weight of 1000 men and the number of men weighing less than 135 pounds is less than the mean weight of 1000 men.

Solve the system of equations.5x + y = 9
3x + 2y = 4

A) (-2, 5)
B) (1, 4)
C) (2, -1)
D) (4, -4)

Answers

Answer:

Step-by-step explanation:

The given system of equations is :

$5x+y=9$ (1)

and $3x+2y=4$ (2)

Multiply equation (1) with 2 and then subtract equation (2) from it, we get

⇒ $10x+2y-3x-2y=18-4$

⇒ $7x=14$

⇒ $x=2$

Substitute the value of x=2 in equation (1), we get

⇒ $5(2)+y=9$

⇒ $10+y=9$

⇒ $y=-1$

Therefore, x=2 and y=-1. that is (2,-1).

you can find replcing x and y by the coordinates of the points
A : 5.-2 + 5 ≠9 not solution
B : 5.1 + 4 = 9 so 3.1 + 2.4 = 11 ≠4 not solution
C: 5.2 + = 9 so 3.2 + 2.-1 = 4 both are right then C is solution
D: 5.4 - 4 = 16 ≠ 9 not solution

Simplify
34 + |18 = -9| × -5.

Answers

Answer:

-11

Step-by-step explanation:

Calculate the absolute value of -9, which is 9.

Multiply 9 by -5, which equals -45.

Finally, add 34 to -45:

34 + (-45) = -11

So, the simplified expression is -11.

Answer:

= -101

step by step explanation:

Calculate the absolute value first:

|18 - (-9)| = |18 + 9| = |27| = 27

Now, we have:

34 + (27 × -5)

Perform the multiplication:

27 × -5 = -135

Finally, add 34 to -135:

34 - 135 = -101

So, the simplified expression is -101

Answers

If you have given an equation, you see the x and y in it. Just taking second equation and think any common factor between x's variable. With common factor, multiply both and you will find the value of y and put it in any equation, you will find the value of X
