2/sqrt 5
by rationalising the denominator,
2/sqrt 5 × sqrt 5/sqrt 5
= 2(sqrt 5)/sqrt 5(sqrt 5)
= 2 sqrt 5/5

hope this helps! :))))
a family of functions is a set of functions whose equations have a similar form. the "parent" of the family is the equation in the family with the <u>simplest</u> form.
Answer:
We failed to accept null hypothesis
Step-by-step explanation:
x= 5.74
Standard deviation = 
n = 65
We will use z test
Formula : 
Substitute the values :
Refer the z table for p value
p value = 0.0314
α = 0.10
p value < α
So, we failed to accept null hypothesis
Answer:
A.
If the depth is 8 feet, the area of the base is 300 square feet. And if the area of the base is 600 square feet, the depth of the water is 4 feet.
Step-by-step explanation:
Depth = Volume/Area
d = V/A
12 = V/200
V = 12 × 200
= 2,400
When d = 8, A = 300
V = dA
= 8 × 300
= 2,400
When d = 4, A = 600
V = 4 × 600
= 2,400.
The first option is correct.
1.5 grams is equal to 1500 milligrams
Half of 6000 is 3000 which is 50%
And half of 3000 is 1500 which is 25% of 6000
