Luna is making a rope ladder. Each step of the ladder is 2 1/3 feet wide and uses an additional 1/2 foot on each end of the step
koban [17]

By taking the quotient between the total length and the length needed for each step, we conclude that Luna can make 9 steps.

<h3>How many steps can she make from the rope?</h3>

To find this, we need to take the quotient between the total length of the rope and the length needed for each step.

She has a total length of 30ft.

For each step she needs (2 + 1/3) ft plus (1/2) ft for each knot, and there are two knots, then each step needs: (2 + 1/3)ft + 2*(1/2)ft = (3 + 1/3) ft.

Then the number of steps that can be made is:

N = (30 ft)/(3 + 1/3) ft. = 9

She can make 9 steps or the lader.

Which of the following are properties of a perfect square trinomial? Select all that apply.. A.Neither of the perfect squares ca
aliya0001 [1]
Definition 1: Perfect squares are numbers or expressions that are the product of a number or expression multiplied to itself (7 times 7 is 49, so 49 is a perfect square).

Definition 2: <span>Binomials are algrebraic expressions containing only two terms.</span><span />
<span>
</span><span>Definition 3: Trinomials are algebraic expressions that contain three terms. </span><span />

Perfect square trinomials are algebraic expressions with three terms that are created by multiplying a binomial to itself. There are two formulas for perfect square trinomials:
(a+b)^2=a^2+2ab+b^2, \\ (a-b)^2=a^2-2ab+b^2.
From these formulas you can see that:
A. <span>"Neither of the perfect squares can have a minus sign" is true statement;
</span>
B. "<span>The first and third terms must be perfect squares" is true statement;
</span>
C. "<span>If the perfect square terms are a^2 and b^2 then the other term must be (ab)^2" is false statement;
</span>
D. "<span>None of the above is a property of a perfect square trinomial" is consequently false statement.
</span>

The length of human pregnancies from conception to birth varies according to a distribution that is approximately Normal with me
andrey2020 [161]

Answer:

0.5466

Step-by-step explanation:

Given that the  length of human pregnancies from conception to birth varies according to a distribution that is approximately Normal with mean 266 days and standard deviation 16 days.

Let X be the length of pregnancies

X is N(266,16)

To find out the probability that pregnancies last between 240 and 270 days (roughly between 8 months and 9 months)

P(240<x<270)

convert each into Z score as z=\frac{x-266}{16}

x=240 means Z = -1.625

x=270 means z=0.25

Required prob

= P(-1.625
