In circle Q with

jonny [76]

Answer:

The minor arc PR is 42 degrees

Step-by-step explanation:

The picture of the question in the attached figure

we know that

The inscribed angle is half that of the arc comprising

so

$m\angle PSR=\frac{1}{2}(arc\ PR)$

we have

$m\angle PSR=21^o$

substitute

$21^o=\frac{1}{2}(arc\ PR)$

$arc\ PR=21(2)=42^o$

Remember that the minor arc in a circle is less than 180 degrees

therefore

The minor arc PR is 42 degrees

Archy [21]

Answer:

$\mathbf{Margin\; of\; error} =$ .0942816

Step-by-step explanation:

Given

Sample size n = 150

Sample proportion ${\widehat{(p)}$ = $\frac{42}{150}$ = 0.28

Confidence interval = $\frac{99}{100}$ = .99

$Margin\; of\; error = z_{\frac{\alpha }{2}}\sqrt{\frac{{\widehat{(p)}}{(1 - \widehat{p})}}{n}}$

$\alpha =$ 1 - confidence interval = 1 - 0.99 = .01

$margin\; of\; error = z_{\frac{.01 }{2}}\sqrt{\frac{(.28) (1 - 0.28)}{150}$

For 99 $\%$ confidence interval

( Z = 2.576 )

$margin\; of\; error = z_{.005 }}\sqrt{\frac{(.28) (1 - 0.28)}{150}$

$margin\; of\; error = 2.576\times\sqrt{\frac{(.28) (1 - 0.28)}{150}$

= .0942816

Rocko paid $12.50 for 25 game tickets.

soldi70 [24.7K]

Answer:

The constant of proportionality is 0.5

Step-by-step explanation:

We are given the following in the question:

Cost of 25 game tickets = $12.50

Cost of 35 game tickets = $17.50

The cost of ticket C(n) is directly proportion to the number of tickets n.

Thus, we can write:

$C(n) \propto n\\C(n) = an$

where a is the constant of proportionality.

Putting values, we get,

$12.50 = 25a\\\\\Rightarrow a = \dfrac{12.50}{25}\\\\\Rightarrow a = 0.5$

Thus, the constant of proportionality is 0.5

Decrease £15890.23 by 16.5%<br> Give your answer rounded to 2 DP.

just olya [345]

Answer:

£13,268.34

Step-by-step explanation:

16.5% of £15890.23

= 16.5/100 × £15890.23

= 0.165 × £15890.23

= £2,621.88795

Therefore,

£15890.23 - £2,621.88795

= £13,268.34205

Approximate to 2 decimal place

= £13,268.34
