X over 85 = 72 over 100

gayaneshka [121]

Answer:

X=61.2

Step-by-step explanation:

x/85 = 72/100

x*100/8500 = 6120/8500

x*100 must equal 6120 therefore x must be 61.2 because 61.2 * 100 is 6120

The base of an isosceles triangle is a fourth as long as the two equal sides. write the perimeter of the triangle as a function

jeka57 [31]

Set the length of the base as x, the two equal sides are then 4x each, so the perimeter is x+4x+4x=9x

Q 11 anybody help me please

kenny6666 [7]

It would be -8d + 3w because

-(8d -3w)
you would be multiplying the hole equation by -1
so 8d would become -8d
and -3w would become positive +3w meaning the answer is -8d +3w

The amount of soda a dispensing machine pours into a 12-ounce can of soda follows a normal distribution with a mean of 12.30 oun

Ugo [173]

Answer: A) .1587

Step-by-step explanation:

Given : The amount of soda a dispensing machine pours into a 12-ounce can of soda follows a normal distribution with a mean of 12.30 ounces and a standard deviation of 0.20 ounce.

i.e. $\mu=12.30$ and $\sigma=0.20$

Let x denotes the amount of soda in any can.

Every can that has more than 12.50 ounces of soda poured into it must go through a special cleaning process before it can be sold.

Then, the probability that a randomly selected can will need to go through the mentioned process = probability that a randomly selected can has more than 12.50 ounces of soda poured into it =

$P(x>12.50)=1-P(x\leq12.50)\\\\=1-P(\dfrac{x-\mu}{\sigma}\leq\dfrac{12.50-12.30}{0.20})\\\\=1-P(z\leq1)\ \ [\because z=\dfrac{x-\mu}{\sigma}]\\\\=1-0.8413\ \ \ [\text{By z-table}]\\\\=0.1587$

Hence, the required probability= A) 0.1587
