Answer:

10.7

Step-by-step explanation:

the tenth place is the first number that comes after the decimal so, that is the number you are rounding. We take a look following that number and it it is equal to or greater than 5, (which it is), we round up one number.

Answer:

10.7

Step-by-step explanation:

Any number between 1-4 rounds down and 5-9 rounds up, so here you will round up. I've included the decimal places as well below. The number after the decimal point is the tenth's place.

Good luck! Hope this helps

I added a screenshot with the head of the question

Answer:
sin (140°)

Explanation:
Angle addition formulas are used to express the trigonometric function in terms of the sum/difference between two angles α and β
These rules are shown in the attached image.

Now, the given expression is::
sin97°cos43°+cos97°sin43°We have:
α = 97°
β = 43°

Comparing the given formula with the general formulas in the image, we would find that the given formula represents the sum of the sin of two angles.

Therefore:
sin97°cos43°+cos97°sin43°
= sin (97°+43°)
= sin (140°)

Hope this helps :)

A manufacturer knows that their items have a normally distributed lifespan, with a mean of 5.8 years, and standard deviation of

fenix001 [56]

Answer:

3.6 years

Step-by-step explanation:

Using the standard normal probability distribution table, we obtain the Zscore which is 10% to left of the distribution.

The Zscore gives, - 1.282

To obtain the number of years, let this be x ;

Recall, the Zscore formula :

Zscore = (x - μ) / σ

x = number of years

μ = 5.8

σ = 1.7

Zscore = (x - μ) / σ

-1.282 = (x - 5.8) / 1.7

-1.282 * 1.7 = x - 5.8

-2.1794 = x - 5.8

-2.1794 + 5.8 = x

x = 3.6206

x = 3.6 years

However, you can’t technically have a .75 of a stall, so you round down to the nearest whole number, which is 27.
