Answer:

x = 6.4 feet.

Step-by-step explanation:

If a triangle has side lengths a, b, and c then its perimeter (P) will be given by ( a + b + c ).

Now, in this problem, the perimeter of a triangle is given to be 27.1 feet,

And its sides are 9.8 feet, 10.9 feet, and x feet.

Therefore, 27.1 = ( 9.8 + 10.9 + x )

⇒ 27.1 = 20.7 + x

⇒ x = 6.4 feet (Answer)

Alla [95]

Answer:

$z=5$

Step-by-step explanation:

We have been given that the The annual salaries of all employees at a financial company are normally distributed with a mean of $34,000 and a standard deviation of $4,000.

To solve our given problem we will use z-score formula.

$z=\frac{x-\mu}{\sigma}$ where,

$z=\text{z-score}$ ,

$x=\text{Sample score}$ ,

$\mu=\text{Mean}$ ,

$\sigma=\text{Standard deviation}$

Upon substituting our given values in z-score formula we will get,

$z=\frac{54,000-34,000}{4,000}$

$z=\frac{20,000}{4000}$

$z=5$

Therefore, the z-score of a company employee who makes an annual salary of $54,000 is 5.

What is the following quotient 3 sqrt 8/ 4 sqrt 6

adell [148]

We have that
(3√8)/(4√6)

we know that
√8---------> √(2³)-----> 2√2
so
(3√8)/(4√6)=(3*[2√2])/(4√6)---> 6√2/(4√6)
√6=√(2*3)---> √2*√3
6√2/(4√6)=6√2/(4√2*√3)----> 6/(4√3)----> 6/(4√3)*(√3/√3)-----> 6√3/(4*3)----> √3/2

the answer is
√3/2

Elanso [62]

Answer:

Total Dolls would Evelyn have had if she had not lost them = 9 Dolls

Step-by-step explanation:

As given,

Total dolls Evelyn had = 9

Total dolls lost = $\frac{1}{3}$ × 9 = 3

So, Now

Evelyn had total dools after lost = 9 - 3 = 6

If she had not lost te dolls , then she had 3 dolls more

∴ we get

If she had not lost any dolls , Evelyn had total dolls = 6 + 3 = 9

So, The answer would be :

Total Dolls would Evelyn have had if she had not lost them = 9 Dolls
