W+2/3=2 5/6 I can't figure out the answer

1 answer:

8 0

If you're solving for W, your answer is w = 2 1/6

First, we would simplify our fractions:
w + 2/3 = 2 5/6 =
w + 2/3 = 17/6

Lastly, we subtract 2/3 on both sides of the equation:
w + 2/3 - 2/3 = 17/6 - 2/3 =
w = 13/6 or w = 2 1/6

Answer:

See below.

Step-by-step explanation:

We need to add up 4 angles to get 360.

Here is what you fill out for the missing boxes:

70 + 70 = 130
70 goes into the smallest angle.
115 + 115 = 230.
If we do 120 or 130, It would make 370 or 390.
130 + 230 = 360.
50 + 50 = 100.
Missing 50 goes into smallest angle.
130 + 130 = 260.
260 + 100 = 360.

To select a __________ random sample, first classify the population into groups of similar individuals, then choose a separate S

Lina20 [59]

Answer:

To select a stratified random sample, first classify the population into groups of similar individuals, then choose a separate SRS in each group and combine these SRS to form the full sample

Step-by-step explanation:

Stratified random sampling involved dividing the population into small groups of similar individuals (called strata) and then from among those groups, a stratified random sample is selected and then, all these samples are combined to form the full sample. Hence, the missing word in this sentence is stratified.

What is the length of x?

Marat540 [252]

Answer:

The length of 'x' is 4

Step-by-step explanation:

We can use the pythagorean theorem to solve this.

The pythagorean theorem is:

$a ^{2} + b^{2} = {c}^{2}$

$a ^{2} + b^{2} = c^{2} \\ {3}^{2} + {b}^{2} = 5^{2} \\ 9 + {b}^{2} = 25 \\ \frac{ - 9 \: \: \: \: \: \: \: \: = - 9}{b ^{2} = \sqrt{16} } \\ b = 4$

Therefore x = 4
