Answer:

She needs to measure the length of the diagonal and two sides of the frame. Then she needs to find the square of each measure. If the sum of the squares of the two smaller sides equals the square of the diagonal, then she created a right triangle.

lions [1.4K]

Answer:0.29

Step-by-step explanation:

An average of six cell phone thefts is reported in San Francisco per day. This means our mean value, u = 6

For poisson distribution,

P(x=r) = (e^-u×u^r)/r!

probability that four cell phones will be reported stolen tomorrow=

P(x=4)= (e^-6×6^4)/4!

= (0.00248×1296)/4×3×2×1

= 3.21408/24=

0.13392

P(x=5)= (e^-6×6^5)/5!

= (0.00248×7776)/5×4×3×2×1

= 19.28448/120

= 0.1607

probability that four or five cell phones will be reported stolen tomorrow

= P(x=4) + P(x=5)

= 0.13392 + 0.1607

= 0.294624

Approximately 0.29

Solve x and give our answer as a improper fraction in its simplest form:
Diano4ka-milaya [45]

Hello!

Explanation:

Distributive property: → a(b+c)=ab+ac

Expand.

6(x-9)=6x-54

6x-54=3x+2

First, add by 54 from both sides of an equation.

6x-54+54=3x+2+54

Then, simplify by equation.

6x=3x+56

You can also subtract by 3x from both sides of an equation.

6x-3x=3x+56-3x

Simplify.

3x=56

Next, divide by 3 from both sides of an equation.

\frac{3x}{3}=\frac{56}{3}

Answer: →\boxed{x=56/3} and x=18.6=19.0

Hope this helps!

Have a great day!
