$(3x)(5y) = (3 \times - 1)(5 \times 2) \\ - 3 \times 10 = - 30 \\ \\ or \: An \: other \: way \\ \\ (3x)(5y) = 15xy \\ 15( - 1)(2) = - 30$

I hope I helped you^_^

According to a report by Scarborough Research, the average monthly household cellular phone bill is $73. Suppose local monthly h

marta [7]

Answer:

The probability that a randomly selected monthly cell phone bill is less than $95 is 0.9772

Step-by-step explanation:

The average monthly household cellular phone bill is $73.

$\mu = 73$

Local monthly household cell phone bills are normally distributed with a standard deviation of $11.

$\sigma = 11$

We are supposed to find the probability that a randomly selected monthly cell phone bill is less than $95 i.e.P(x<95)

$Z=\frac{x-\mu}{\sigma}$

$Z=\frac{95-73}{11}$

Z=2

Refer the z table for p value

So,p value = 0.9772

Hence the probability that a randomly selected monthly cell phone bill is less than $95 is 0.9772

The base of a rectangle is 6cm longer than its height. The area of a rectangle is 91cm squared. What is the perimeter of the rec

r-ruslan [8.4K]

Width = 7cm

Length = 13cm

<u>Explanation:</u>

Area of rectangle = $91cm^{2}$

Let width of the rectangle = b ,

So, length = b+6

Area of rectangle = (length X width) - eqn 1

Putting the value of length and width in above equation 1,

$91cm^{2} = b (b+6)\\91 = b^{2}+6b\\b^{2} + 6b-91 = 0\\$

On solving the quadratic equation we get,

b = 7cm

So, width (b) = 7cm

and length = 7+6

l = 13cm

Hence,

Width = 7cm

Length = 13cm
