Figure are significant if they are a number greater than 0, if they're after a decimal place, or if they're a 0 in between significant numbers

190 has 2 sig figs
1.8 has 2 sig figs
26 has 2 sig figs
206 has 3 sig figs

thus, the answer is 206

Musya8 [376]

Answer: The population proportion is between 0.34 and 0.46 .

Step-by-step explanation:

Interpretation of 95% confidence interval : A person can be about 95% confident that the true population parameter lies in the interval.

A confidence interval is constructed for an unknown population proportion, p. A sample is collected, and the 95% confidence interval is calculated to be 0.40 ± 0.06.

i.e. Lower limit = 0.40-0.06=0.34

Upper limit =  0.40+0.06=0.46

i.e. 95% confidence interval = (0.34, 0.46)

i.e. A person can be about 95% confident that the true population proportion (p) lies in the interval  (0.34, 0.46).

⇒ It is most accurate to say that there is approximately 95% confidence in the assertion that:

The population proportion is between 0.34 and 0.46 .

What is the solution to the equation below? <br>-3 + sqrt 2x - 1 =8​
sattari [20]

Answer:

x=61

Step-by-step explanation:

-3+\sqrt{2x-1} =8

\sqrt{2x-1} -3=8

<u><em>Add 3 to both sides of the equation:</em></u>

\sqrt{2x-1}-3+3=8+3

\sqrt{2x-1}=11

<u><em>Solve the square root:</em></u>

\sqrt{2x-1}=11

2x-1=11^{2}

2x-1=121

2x-1+1=121+1<em> {add 1 to both sides}</em>

2x=122

x=122/2

x=61

<u><em>hope this helps.......</em></u>
