3 0

Answer:

2200 feet

Step-by-step explanation:

1. Find necessary angles

45˚ + 45˚ = 90

so airplane and height is 45˚ in between

d = distance

cos 45 = 2200/d

d = 2200/cos 45

d ≈ 3111.27 > all of the answers

If it is from ground to house then its 2200 ft, same as plane to ground

Insurance companies A and B each earn an annual profit that is normally distributed with the same positive mean. The standard de
krok68 [10]

Answer:

C. 0.98

Step-by-step explanation:

Let x be the mean of Company A and B annual profit and x/2 and y are standard deviation of Company A and B annual profit.

P(B<0) = 0.9*P(A<0)

P(Z<(0-x)/y) = 0.9*P(Z<(0-x)/(x/2))

P(Z<-x/y) = 0.9*P(Z<-2)

P(Z<-x/y) = 0.0205

x/y =2.04

Or y/x = 1 /2.05

y/x =0.49

Ratio of the standard deviation of company B annual profit to the standard deviation of company A annual profit =y/(x/2)

= 2*(y/x)

= 2*0.49

= 0.98

A parallelogram has a base of length 2x + 1 and a height of x + 3 and has an area of
storchak [24]

Answer:

  • base 7
  • height 6

Step-by-step explanation:

Using the given expressions, we can write the area as ...

  A = BH

  42 = (2x +1)(x +3) = 2x^2 +7x +3

  2x ^2 +7x -39 = 0

  (x -3)(2x +13) = 0

  x = 3   or   -6.5  . . . . .  these values make the factors be zero

In order for the parallelogram to have positive dimensions, the value of x must be 3. So, the base and height are ...

  base = 2(3) +1 = 7

  height = 3 +3 = 6

8% of the employees at a shop work part-time.
nikitadnepr [17]

There are 50 employees in total

<h3>How to determine the total employee?</h3>

The given parameter is:

Part-time = 8% of total employee

Rewrite as:

Part-time = 8% * total employee

There are 4 part-time employees.

So, we have:

8% * total employee = 4

Divide both sides by 8%

total employee = 50

Hence, there are 50 employees in total
