Answer:

There are 60 activity booklets in the media lab.

Step-by-step explanation:

- 30/2 = 15

Why divide those numbers?

For every 2 computers in a lab with 30 computers means you have to divide

- 15x4 = 60

Why multiply those numbers?

4 activity booklets for every 2 computers in a lab of 30 computers, so multiply

I hope this helps.

The number of chocolate chips in an​ 18-ounce bag of chocolate chip cookies is approximately normally distributed with mean 1252
svp [43]
The z-score is given by the formula:
z=(x-μ)/σ
μ=1252
σ=129
The answer to the questions given will be as follows:
a] <span>what is the probability that a randomly selected bag contains between 1100 and 1400 chocolate​ chips?
z=(1400-1252)/129
z=1.15625
P(x</span>≤<span>1400)=0.8770

z=(1100-1252)/129
z=0.1190
P(X</span>≤1100<span>)=0.1190

the answer will be:
P(1100</span>≤x≤1400<span>)=0.8770-0.1190=0.758

b]</span><span>what is the probability that a randomly selected bag contains fewer than 1000 chocolate​ chips? 
</span>z=(1000-1252)/129=-1.954
P(X≤1000)=0.0256

c] <span>what proportion of bags contains more than 1200 chocolate​ chips?
z=(1200-1252)/129
z=-0.4031
P(X</span>≥1200<span>)=1-P(X</span>≤1200<span>)=1-0.4031=0.5969

The length of each side of an equilateral triangle is increased by 20%, resulting in triangle ABC. If the length of each side of
kompoz [17]

Answer: Area of ΔABC is 2.25x the area of ΔDEF.

Step-by-step explanation: Because equilateral triangle has 3 equal sides, area is calculated as

A=\frac{\sqrt{3} }{4} a^{2}

with a as side of the triangle.

Triangle ABC is 20% bigger than the original, which means its side (a₁) measures, compared to the original:

a₁ = 1.2a

Then, its area is

A_{1}=\frac{\sqrt{3} }{4}(1.2a)^{2}

A_{1}=\frac{\sqrt{3} }{4}1.44a^{2}

Triangle DEF is 20% smaller than the original, which means its side is:

a₂ = 0.8a

So, area is

A_{2}=\frac{\sqrt{3} }{4} (0.8a)^{2}

A_{2}=\frac{\sqrt{3} }{4} 0.64a^{2}

Now, comparing areas:

\frac{A_{1}}{A_{2}}= (\frac{\sqrt{3}.1.44a^{2} }{4})(\frac{4}{\sqrt{3}.0.64a^{2} } )

\frac{A_{1}}{A_{2}} = 2.25

<u>The area of ΔABC is </u><u>2.25x</u><u> greater than the area of ΔDEF.</u>
