A number, x, rounded to 1 decimal place is 3.7 Write down the error interval for x.

soldier1979 [14.2K]

Answer: (3.65, 3.74)

Step-by-step explanation:

Now, when we round a number to a given decimal place, we need to look at the decimal to the left of the decimal place where we are rounding.

if it is 5 or more, we round up

if it is smaller than 5, we round down.

Then for example, if we want to round:

4.534

to the first decimal place, we need to look at the second decimal place.

we can see that it is a 2.

Then we round down, and get:

4.5

Now we know that, when rounding to the first decimal place, we have:

x = 3.7

Then the maximum value that x could have is:

x = 3.74 (because here we round down to 3.7)

and the minimum value that x could have is:

x = 3.65 (because here we round up to 3.7)

Then the error interval for x is:

(3.65, 3.74)

Complete the proof by providing the missing statement and reasons

Lisa [10]

Answer:

In triangle SHD and triangle STD.

$\overline{SD} \perp \overline{HT}$ [Side]

Since, a line is said to be perpendicular to another line if the two lines intersect at a right angle.

⇒ $\angle SDH = \angle SDT = 90^{\circ}$

$\overline{SH} \cong \overline{ST}$ [leg] [Given]

Reflexive property states that the value is equal to itself.

$\overline{SD} \cong \overline{SD}$ [Leg] [Reflexive property]

HL(Hypotenuse-leg) theorem states that any two right triangles that have a congruent hypotenuse and a corresponding congruent leg are the congruent triangles.

then, by HL theorem;

$\triangle SHD \cong \triangle STD$ Proved!
