Solve for x= ax2 + b = c

alekssr [168]

Answer:

x = ± $\sqrt{\frac{c-b}{a} }$

Step-by-step explanation:

Given

ax² + b = c ( subtract b from both sides )

ax² = c - b ( divide both sides by a )

x² = $\frac{c-b}{a}$ ( take the square root of both sides )

x = ± $\sqrt{\frac{c-b}{a} }$

Find both unit rates. 1435 points scored in 25 games + Brainliest!!

kozerog [31]

In this case, the unit is points (1,435) and the time is games (25). So, we divide the unit by the rate to get the unit rate of 57.5.

On the flip side, we can treat the game as the unit and the points as the rate to get 0.017 games per point.

Use the given degree of confidence and sample data to construct interval for the population proportion. Of 369 randomly selected

Alexxx [7]

Answer:

e) (3.77%, 8.70%)

95% confidence interval for the percentage of all medical students who plan to work in a rural community

(3.83% , 8.69%)

95% confidence level for the population proportion who blame oil companies for the recent increase in gasoline prices

(0.406 , 0.454)

Step-by-step explanation:

Step(i):-

Given random sample size 'n' = 369

Sample proportion

$p = \frac{x}{n} = \frac{23}{369} = 0.0623$

95% confidence intervals are determined by

$(p^{-} - Z_{0.05} \sqrt{\frac{p(1-p)}{n} } , p^{-} + Z_{0.05} \sqrt{\frac{p(1-p)}{n} })$

$(0.0623 - 1.96 \sqrt{\frac{0.0623(1-0.0623)}{369} } , 0.0623 + 1.96\sqrt{\frac{0.0623(1-0.0623)}{369} })$

(0.0623 - 0.0246 , 0.0623 + 0.0246)

(0.0383 , 0.0869)

(3.83% , 8.69%)

95% confidence interval for the percentage of all medical students who plan to work in a rural community

(3.83% , 8.69%)

Step(ii):-

Given 43% of those polled blamed of companies the most for the recent increase in gasoline prices

sample proportion 'p' = 0.43

Given Margin of error (M.E) = 0.024

95% confidence intervals are determined by

$(p^{-} - Z_{0.05} \sqrt{\frac{p(1-p)}{n} } , p^{-} + Z_{0.05} \sqrt{\frac{p(1-p)}{n} })$

$(0.43 - 0.024 } , 0.43 +0.024 )$

(0.406 , 0.454)

Final answer:-

95% confidence level for the population proportion who blame oil companies for the recent increase in gasoline prices

(0.406 , 0.454)
