Answer:

Step-by-step explanation:

GI is made up of the segments GH and HI. In other words:

$GI=GH+HI$

We know that GH is 2 and GI is 7. Substitute:

$7=2+HI$

Subtract 2 from both sides:

$HI=5$

So, our answer is B.

And we're done!

Suppose that the value of a stock varies each day from $10.82 to $25.17 with a uniform distribution. Find the third quartile, i.

Zarrin [17]

Answer: Third quartile =$21.58

Step-by-step explanation:

Let x be value of a stock .

For uniform distribution,

probability density function = $\dfrac{1}{b-a}=\dfrac{1}{25.17-10.82}=\dfrac1{14.35}=\dfrac{100}{1435}$

Let a be the stock value such that P(x<a) =75% or 0.75

$\Rightarrow\ \int ^{a}_{10.82}f(x)\ dx=0.75\\\\\Rightarrow\ \int ^{a}_{10.82}\dfrac{100}{1435}\ dx=0.75\\\\\Rightarrow\dfrac{100}{1435}[x]^{a}_{10.82}=0.75\\\\\Rightarrow \dfrac{100}{1435}(a-10.82)=0.75\\\\\Rightarrow a-10.82=0.75\times\dfrac{1435}{100}\\\\\Rightarrow a-10.82=10.7625\\\\\Rightarrow a= 10.7625+10.82= $$21.5825\approx $$21.58$

Hence, 75% of all days the stock is below $21.58 or Third quartile =$21.58 .

On one side of a balancing scale there are 5 blocks: 3 weighing 3 grams each and 2 weighing x each. The scale is balanced if 8 b

natita [175]

Answer:

The weight of unknown block on each side of the scale is 1.5 grams.

Step-by-step explanation:

The number of blocks on 1 side = 5 blocks

Now, 3 blocks = 3 grams each

⇒Total weight of 3 blocks = (3 grams )times 3 = 9 grams

2 blocks = x grams each

⇒Total weight of 2 blocks = (x grams ) 2 = 2 x grams

So the total weight on 1 side = weight of 5 blocks combined

= 9 grams + 2x grams = (9 + 2x) grams

The total weight on other side of scale = 8 blocks times (x grams)

= (8x) grams

Now, The SCALE IS BALANCED if :

(9 + 2x) grams = (8x) grams

or, 9 + 2x = 8x

⇒9 = 8x - 2x = 6x

or, x = 9/6 = 1.5

⇒ x = 1.5 grams

Hence, the weight of unknown block on each side of the scale is

1.5 grams, so that the scale is balanced.
