Answer:

$Probability = 0.7374$

Step-by-step explanation:

Given

Represent the probability that a student has a phone with p

$p = 97\%$

Required

Determine the probability that 10 has

This is calculated as thus:

$Probability = p^n$

Where n = 10

$Probability = (97\%)^{10}$

$Probability = 0.97^{10}$

$Probability = 0.73742412689$

$Probability = 0.7374$ --- Approximated

Can someone help solve

leva [86]

$\frac{-18z^{7}y^{5}-9z^{9}y^4+18z^6y^8}{9zy^{2} }= -2z^6y^3-z^8y^2+2z^5y^6$

When variables with exponents are divided by each other, you subtract the exponents.

For example:

$\frac{x^2}{x^1} = x^{2-1} =x^1$

$\frac{x^5}{x^3} =x^{5-3} = x^2$

Determine whether a triangle can be formed with the given side lengths. If so, use Heron's formula to find the area of the trian

mart [117]

Answer:

The area is 11317.51

Step-by-step explanation:

The sum of 2 sides must be less than the third side (largest side) for a triangle to be formed.

b+c<a

133+174 < 240

A triangle can be formed

To use Herons formula for the area

We find S = 1/2( a+b+c)

= 1/2(240+133+174)

= 1/2 (547)

= 273.5

Area = sqrt( S (S-a) (S-b)(S-c))

sqrt((273.5 ) (273.5 -240) (273.5-133) (273.5-174))

sqrt((273.5)(33.5) (140.5) (99.5))

sqrt(128085964.4)

11317.50699

The area is 11317.51
