Answer:

√2=1.414

then :√8 +2√32 +3√128+4√50

√8=√2³ =2√2

2√32=√2^5 = 4*2√2 = 8√2

3√128 = 3√2^6*2=8*3√2 =24√2

4√50 =4√5²*2= 20√2

add results : 2√2+8√2 +24√2+20√2=54√2

<h2>54√2=54×1.414=76.356 ( it is not in the options)</h2>

x=7-4√3

√x+ 1/√x

√(7-4√3) +1/√(7-4√3) =

(8-4√3)/√(7-4√3)

(8-6.93)/√(7-6.93) = 4 ( after rounded to the nearest whole number)

4 is your answer

A coin is being flipped 400 times. What is the probability of it landing on heads at most 170 times, rounded to the nearest tent
lisabon 2012 [21]

Hello!

We have two probabilities we can use; we have 170/400, for our experiment, and 1/2, which is our theoretical probability.

To solve, we just multiply the two probabilities.

\frac{170}{400}(1/2)=0.2125≈21.3

Therefore, we have about a 21.3% chance of this event occurring.

I hope this helps!

During the first month of sales, a company sold 1,300,000
schepotkina [342]

The right answer is Option C.

Step-by-step explanation:

Given,

Smartphone sold = 1300000 units

Smartphones returned = 15%

No. of smartphones returned = 15% of smartphones sold

No. of smartphones returned =\frac{15}{100}*1300000

No. of smartphones returned = 0.15*1300000 = 195000 units

As sales and return rate remains same, therefore,

Returns in 6 months = 6*per month returns

Returns\ in\ 6\ months=6*195000=1170000\ units

1170000 units will be returned to the company during 6 months.

The right answer is Option C.

Keywords: multiplication, return rate
