3 0

Answer:

31.57 cars is the answer rounded to the hundredth, but since its cars you might want to put just 31 since half a car cant pass through. it depends on what your teacher wants really.

Step-by-step explanation:

70=2.1n+3.7

70-3.7=2.1n

66.3=2.1n

66.3/2.1=n

31.57=n

The percentage of consignors who receive a check for more than $370 is:

= 16%.

Step-by-step explanation:

Mean of consignor check, μ = $480

Standard deviation, σ = $110

Value of check received, x > $370

Solution: find the z-score to determine the percentage of consignors who receive a check for more than $370:

z = (x-μ)/σ

z= ($370 - $480)/$110

z = -$110/$110

z = -1.00

Percentage of consignors who receive a check for more than $370

= 0.15866

= 0.16

= 16%

The answer would be B. As you can see Angle A and angle B are connected by that line and together they would equal 90 degrees like on the other side of line AB.

ASAP PLEASE HELP Find the​ x- and​ y-intercepts of the line that passes through the given points.
Umnica [9.8K]

Answer:

Set it up using the slope from the two points. (c - (-5))/3 - 1 = slope = (c + 5)/2. Now put this into slope intercept since they give you the y intercept of 7. y = x*(c + 5)/2 + 7. Now put in the point, (1,-5). -5 = 1*(c+5)/2 + 7. Subtract 7 from both sides. Now multiply through and you can solve for c.
