What is the probability that at most 2 minutes elapse between 1 call and the next

Answers

Answer 1

Answer:

The answer is "0.6227 and 0.5971".

Step-by-step explanation:

[tex]\to p(x\leq 2)=p(0)+p(1)+p(2)[/tex]

                  [tex]=e^{-2.2}(1+2.2^{1}+\frac{2.2^2}{2!})\\\\=0.6227[/tex]

[tex]\to x \sim emp(\frac{1}{2.2})\\\\\to f(x)=\frac{1}{2.2} emp1-\frac{x}{2.2}[/tex]

[tex]\to p(x \leq 2)=\int^{2}_{0} \frac{1}{2.2} emp1(-\frac{x}{2.2}\ dx[/tex]

                  [tex]=1-emp1-2|2.2\\\\=0.5971[/tex]

Kimberly wants to get a backpack that cost $35 it is now on sale for 15% off she has to pay 7.5% sales tax what is the sales price of the backpack

Answers

Answer:

$44.26

Step-by-step explanation:

The computation of the sales price is shown below:

Its cost is $35

There is a sale off i.e. 15% off

And, the sales tax rate is 7.5%

SO, the sale price is

= $35 × 100 ÷ 85 + ($35 × 100 ÷ 85) × 7.5%

= $41.17 + $41.17 × 7.5%

= $41.17 + $3.09

= $44.26

Hence, the sales price is $44.26

does 20, 40, 30 form a pythagorean triple

Answers

Answer:

Step-by-step explanation:

If it is a Pythagorean Triple the hypotenuse and the legs of a right triangle will all be integer values where

c^2=a^2+b^2

In this case, this isn’t even a right triangle as

20^2+30^2=40^2

400+900=1600

1300!=1600

because 1300 does not equal 1600 this is not a Pythagorean Triple.

Answers

ANSWER :

x⁰ = 360 degree- ( 246 + 66)

= 360 degree- 312

= 48

Answer:

x = 114

Step-by-step explanation:

Remark

You are trying to figure out what the arc is in degrees. The arc formula is

Intersect angle = 1/2( the furthest arc - the smaller closer arc).

Givens

Intersect angle = 66 degrees

Closer arc = x

Further or largest Arc = 246

Solution

66 = 1/2 (246 - x)                  Multiply both sides by 2 and remove the brackets.

132 = 246 - x                        Subtract 246 from both sides.

132 - 246 = - x

- 114 = - x                             Multiply both sides by -1

-1 (-114) = -1 * (-x)

x = 114

Find the value of x. Round to the nearest whole number.
