when you multiply scientific notation numbers add the exponents ( -8 + -10 = -18)

 now multiply 2.5 *9 = 22.5

 so you now have 22.5x10^-18

now make 22.5 a real scientific number by moving the decimal point 1 place to the right, which subtracts 1 from the exponent

 so you get:

2.25x10^-17

2.25 x 10^-17. Because it's negative you move the decimal to the left. So 2.5 x 10^-8 is .000000025 and 9 x 10^-10 is .0000000009.

Answer:

0.33

Step-by-step explanation:

Given the following :

P(speeding) = p(s) = 0.75

P(being stopped) = p(t)

P(speeding and gets stopped) = p(s n t) = 0.25

Find the probability that he is stopped, given that he is speeding is written as P(t | s) ;

P(t | s) = p(s n t) / p(s)

P(s n t) = 0.25

P(s) = 0.75

Hence,

P(t | s) = 0.25 / 0.75

P(t | s) = 0.33

Please help me anyone i need this in 10 minutes
Radda [10]

Given:

The rate of interest on three accounts are 7%, 8%, 9%.

She has twice as much money invested at 8% as she does in 7%.

She has three times as much at 9% as she has at 7%.

Total interest for the year is $150.

To find:

Amount invested on each rate.

Solution:

Let x be the amount invested at 7%. Then,

The amount invested at 8% = 2x

The amount invested at 9% = 3x

Total interest for the year is $150.

x\times \dfrac{7}{100}+2x\times \dfrac{8}{100}+3x\times \dfrac{9}{100}=150

Multiply both sides by 100.

7x+16x+27x=15000

50x=15000

Divide both sides by 50.

x=\dfrac{15000}{50}

x=300

The amount invested at 7% is 300.

The amount invested at 8% is

2(300)=600

The amount invested at 9% is

3(300)=900

Therefore, the stockbroker invested $300 at 7%, $600 at 8%, and $900 at 9%.

Serjik [45]
The central angles are equal...360/n in this case n=6 so the angles are all 60 degrees...

The arc lengths are the circumference of the pizzas.  4p" and 14p" respectively.

sveta [45]

If you were to draw another line connecting the two top corners, you would make an equilateral triangle.

An equilateral triangle has 3 60 degree angles.

The angle = 60 degrees.
