This is a problem of Standard Normal distribution.
We have mean= 12 grams
Standard Deviation = 2.5 grams
First we convert 8.5 to z score. 8.5 converted to z score for given mean and standard deviation will be:

So, from standard normal table we need to find the probability of z score to be less than -1.4. The probability comes out to be 0.0808
Thus, the <span>
probability that the strawberry weighs less than 8.5 grams is 0.0808</span>

Step-by-step explanation:
Answer:
Fgh= -5x^3-^2+45x+9
Gfh= (3-x)(5x+1)(x+3)
I don't think you can do anything with the second one.

Answer:
8/35,9/35
Step-by-step explanation:
L.C.M. of 5 and 7=5×7=35
1/5×7/7=7/35
2/7×5/5=10/35
numbers between 7/35 and 10/35 are 8/35,9/35
actually there are infinite numbers
like 71/350,72/350,73/350,...
Answer:
3.14 cm squared
Step-by-step explanation:
First, identify the formula necessary to calculate the area of the circle.
Area of a circle = pi x r^2
Remember, the radius is just half of the diameter! Then to square a number, is to multiply it by itself once.
pi x 1^2 =?
pi x 1
Pi
The circumference of your circle is approximately 3.14 cm squared.
