James sees a truck at the dealership for $28,000
Lera25 [3.4K]

Answer:

The correct answer is C. $28,200.

Step-by-step explanation:

Given that James saw a truck at the dealership for $ 28,000 base price, $ 1,300 premium interior, $ 1,200 navigation touch-screen, and $ 1,700 smart traffic sensors, if his current vehicle is worth $ 5,000 and he's offered a 60% trade-in rate, to determine what is the total cost of the car after the $ 1,000 destination fee, the following calculation must be made:

28,000 + 1,300 + 1,200 + 1,700 - (5,000 x 60/100) = X

32,200 - (5,000 x 0.6) = X

32,200 - 3,000 = X

29,200 = X

29,200 - 1,000 = 28,200

Therefore, the total cost of the car after the $ 1,000 destination fee is $ 28,200.

Write the equation in slope-intercept form that contains the following point and is perpendicular to the given line
Len [333]

Answer:

y = 1/4 x -3

Step-by-step explanation:

y = -4x + 3;

the slope of this equation is -4

we want the slope perpendicular to this

take the negative reciprocal

- (-1/4) = 1/4

so the slope of our line will be 1/4

we have the slope and a point so we can use point slope form

y-y1 = m (x-x1)

y--2 = 1/4(x-4)

y+2 = 1/4 (x-4)

we need to change it to slope intercept form (y=mx+b)

distribute

y+2 = 1/4 x -1/4*4

y+2 = 1/4x -1

subtract 2 from each side

y +2-2 = 1/4 x -1-2

y = 1/4 x -3

the slope is 1/4 and the y intercept is -3

In the country of United States of Heightlandia, the height measurements of ten-year-old children are approximately normally dis
aliya0001 [1]

(A)

P(<em>X</em> < 61.25) = P((<em>X</em> - 55.4)/4.1 < (61.25 - 55.4)/4.1)

… ≈ P(<em>Z</em> ≤ 0.1427)

… ≈ 0.5567

(B)

P(<em>X</em> > 46.5) = P((<em>X</em> - 55.4)/4.1 > (46.5 - 55.4)/4.1)

… ≈ P(<em>Z</em> > -2.1707)

… ≈ 1 - P(<em>Z</em> ≤ -2.1707)

… ≈ 0.9850
