In the 2006 Winter Olympics, Sweden won 3 medals more than China. Germany
muminat

Germany secured 29 medals

Step-by-step explanation:

In the 2006 Winter Olympics

  • Sweden won 3 medals more than China
  • Germany  secured one more than twice the number of medals bagged by Sweden
  • 54  medals were won in all

We need to find how many medals did Germany secure

Assume that x represents the number of medals that Sweden won

∵ Sweden won x medals

∵ Sweden won 3 medals more than China

- That means chine won 3 medals less than x

∴ China won = x - 3 medals

∵ Germany  secured one more than twice the number of

   medals bagged by Sweden

- That means multiply x by 2 and add 1

∴ Germany secured = 2x + 1 medals

∵ 54  medals were won in all

- That means add the number of medals of the 3 countries

  and equate the sum by 54

∵ x + (x - 3) + (2x + 1) = 54

- Add like terms in the left hand side

∴ (x + x + 2x) + (-3 + 1) = 54

∴ 4x - 2 = 54

- Add 2 to both sides

∴ 4x = 56

- Divide both sides by 4

∴ x = 14

∵ Germany secured 2x + 1

- Substitute the value of x by 14

∴ Germany secured ⇒ 2(14) + 1 = 28 + 1 = 29

Germany secured 29 medals

Natali [406]

Answer:

probability that their average salary is more than $77,500 is 0.1587

Step-by-step explanation:

standard error

= 10,000/sqrt(16)

=10,000/4

= 2500 

(77,500 - 75000)/2500

2,500/2500

= 1 

p (z > 1) = .1587

So, the probability that their average salary is more than $77,500 is 0.1587

Write the slope intercept form of the equation of the line through the given point
ozzi

Answer:

y =  -\frac{3}{4}x

Step-by-step explanation:

slope-intercept form: y = mx + b

Given: slope(m) = -\frac{3}{4}, point (4, -3)

We already have the value of m, but we need to find the value of b. To do this, input the given values of the slope and the point into the equation:

-3 =  -\frac{3}{4}(4) + b

Solve for b:

-3 =  -\frac{3}{4}(4) + b

-3 = -3 + b

0 = b

The value of b is zero. We can now write the equation:

y =  -\frac{3}{4}x + 0

y =  -\frac{3}{4}x

The equation written in slope-intercept form is: y =  -\frac{3}{4}x
