Scorpion4ik [409]

<span>Given number: Two hundred billion in half, how to write this one in standard form
let us first simplify each statement:
=> two hundred billion = 200 000 000 000
=> in half meaning = half of the given number or divide the given number by 2 to get the answer
=> 200 000 000 000 / 2
Show, the ½ of two hundred billion in standard form
=> Thus, two hundred billion in half is equals to 100 000 000 000

Solve: −3(5+8x)−20≤−11

Tatiana [17]

-3(5 + 8x) - 20 ≤ -11 |use distributive property: a(b + c) = ab + ac

-15 - 24x - 20 ≤ -11

-35 - 24x ≤ -11 |add 35 to both sides

-24x ≤ 24 |change signs

24x ≥ -24 |divide both sides by 24

x ≥ -1

An article claims that 12% of trees are infested by a bark beetle. A random sample of 1,000 trees were tested for traces of the

inna [77]

Answer: 0.6812

Step-by-step explanation:

Let p be the population proportion of trees are infested by a bark beetle.

As per given: p= 12%= 0.12

Sample size : n= 1000

Number of trees affected in sample = 1000

Sample proportion of trees are infested by a bark beetle. = $\hat{p}=\dfrac{127}{1000}=0.127$

Now, the z-test statistic : $z=\dfrac{\hat{p}-p}{\sqrt{\dfrac{p(1-p)}{n}}}$

So, $z=\dfrac{0.127-0.12}{\sqrt{\dfrac{0.12\times 0.88}{1000}}}$

$z=\dfrac{0.007}{\sqrt{\dfrac{0.1056}{1000}}}\\\\\\=\dfrac{0.007}{\sqrt{0.0001056}}\\\\\\=\dfrac{0.007}{0.010276}\approx0.6812$

Hence, the value of the z-test statistic = 0.6812 .

Which is longer 2 meters or 200 cent a meters or 2.05 meters

Yuri [45]

Solving this requires use of conversions

we already know that
2.05 m > 2 m

all that's left is the question
200 cm vs. 2.05 meters

I we know our equivalencies, we know that
100 cm = 1 m

if this is so then
200 cm = 2 m

we already know that
2.05 m > 2 m

so it must also be that
2.05 m > 200 cm

$2.05 \: meters$
