Explain why it is not possible to charge an electroscope by Touch by touching the cup with a finger

Tell whether the angles are adjacent or vertical. Then find the value of x.

Nimfa-mama [501]

Answer:

adjacent, x=15

Step-by-step explanation:

the angels are connected so they are adjacent, the red box shows that it is a 90 degree angle so adding both angels together means 90=6x so x=15

Bill and George go target shooting together. Both shoot at atarget at the same time. Suppose Bill hits the target withprobabilit

german

Answer: (a) $\frac{2}{9}$ (b) $\frac{6}{41}$

Step-by-step explanation:

(a) P( Bill hitting the target) = 0.7 P( Bill not hitting the target) = 0.3

P( George hitting the target) = 0.4 P(George not hitting the target) = 0.6

Now the chances that exactly one shot hit the target is = 0.7 x 0.6 + 0.4 x 0.3

= 0.54

Chances that George hit the target is = 0.4 x 0.3 = 0.12

So given that exactly one shot hit the target, probability that it was George's shot = $\frac{0.12}{0.54}$ = $\frac{2}{9}$ .

(b) The numerator in the second part would be the same as of (a) part which is 0.12.

The change in the denominator will be that now we know that the target is hit so now in denominator we include the chance of both hitting the target at same time that is 0.4 x 0.7 and the rest of the equation is same as above i.e.

Given that the target is hit,probability that George hit it = $\frac{0.4\times 0.3}{0.7\times 0.6 +0.4\times 0.3+0.4\times 0.7}$ = = $\frac{6}{41}$

University officials say that at least 70% of the voting student population supports a fee increase. If the 95% confidence inter

yanalaym [24]

Answer:

We are 95% sure that the true proportion of students that supports a fee increase is between 0.75 and 0.85.

Step-by-step explanation:

The interpretation of a x% confidence interval of proportions being between a and b is that:

We are x% sure that the true proportion of the population is between a and b.

If the 95% confidence interval estimating the proportion of students supporting the fee increase is (0.75; 0.85), what conclusion can be drawn

We are 95% sure that the true proportion of students that supports a fee increase is between 0.75 and 0.85.
