Answer:
C is the answer
Step-by-step explanation:
Garden dimensions:
y = width, 4y = length (because it says the length is four times the width)
equation:
y + y + 4y + 4y = 70
=> 10y = 70
=> y =70

The probability that a normally distributed dataset with a mean, μ, and statndard deviation, σ, exceeds a value x, is given by

Given that t<span>he
weight of corn chips dispensed into a 14-ounce bag by the dispensing
machine is a normal distribution with a
mean of 14.5 ounces and a standard deviation of 0.2 ounce.
</span>If <span>100 bags of chips are randomly selected the probability that the mean weight of these 100 bags exceeds 14.6 ounces is given by

Therefore, the probability that </span><span>the mean weight of these 100 bags exceeds 14.6 ounces is</span> 0.
Answer:
The area of the circle is 
Step-by-step explanation:
we know that
The area of a circle is equal to

we have
-----> the radius is half the diameter
substitute the value


Answer:
(x,y)=(5,-1)
Step-by-step explanation:
1. 2x+y=9 ---> y=9-2x
2. Substitute y=9-2x into 3x-2y=17 ---> 3x-2(9-2x)=17 ---> 3x-18+4x=17 --> 7x=35 ---> x=5.
3. Substitute x=5 into 2x+y=9 ---> 2*5+y=9 ---> y=9-10 ---> y= -1
