For this case, the first thing we must do is define a variable.
We have then:
x: unknown number
We now write the expression that models the problem:

From here, we clear the value of x.
We have then:




Answer:
4/9 divided by 1/27 equals 12
Answer
6th of the power of 1 would be 5th power
Step-by-step explanation:
Answer:
x√5 = x square root 5
Step-by-step explanation:
√35x^5 ÷ √7x^3 = √(35x^5 / 7x^3)
√(35x^5 / 7x^3) = √(5x^5 / x^3)
√(5x^5 / x^3) = √5x^(5-3) = √5x²
√5x² = x√5
Answer:
9/10
Step-by-step explanation:
step 1
Compare the slopes



therefore
An experienced skier would like the 9/10 hill slope because it is steeper, while the 1/10 is a softer slope.
Answer:
Step-by-step explanation:
Given that a survey showed that 72% of adults need correction (eyeglasses, contacts, surgery, etc.) for their eyesight
X - number of people who need correction for their eyesight
X is binomial since each event is independent and there are only two outcmes.
X (18, 0.72)
Required probability = the probability that no more than 1 of them need correction for their eyesight.
=P(X=0)+P(X=1)=0.00000296+0.000137
=0.00014
Yes 1 is a significantly low number as probability is almost zero.
