What happens to the center of a figure when it is dilated about the origin?
alina1380 [7]
There are 2 answers for this in my opinion
1. nothing happens because its still in the origin and that won't change
2. depending on which way you turn it the points will change based on that

so if you know how to use a graph you should be good

The mean yield of corn in the United States is about 135 bushels per acre. A survey of 40 farmers this year gives a sample mean
Ostrovityanka [42]

Answer:

z = \frac{138.8-135}{\frac{10}{\sqrt{40}}}= 2.403

Step-by-step explanation:

Data given and notation  

\bar X=138.8 represent the sample mean

\sigma = 10 represent the population standard deviation

n=40 sample size  

\mu_o =135 represent the value that we want to test

t would represent the statistic (variable of interest)  

p_v represent the p value for the test (variable of interest)  

Solution to the problem

We need to conduct a hypothesis in order to check if the true mean for the bushlels per acre is not 135, the system of hypothesis would be:  

Null hypothesis:\mu = 135  

Alternative hypothesis:\mu \neq 135  

And the z statistic is given by:

z= \frac{\bar X -\mu}{\frac{\sigma}{\sqrt{n}}}

And replacing we got:

z = \frac{138.8-135}{\frac{10}{\sqrt{40}}}= 2.403

Can you help me please ​

Answer:

\approx 14.7 \:  {yd}^{2}

Step-by-step explanation:

Area of unshaded sector

=  \frac{(360 - 167 )\degree}{360 \degree}  \times \pi {r}^{2}  \\  \\  17.8=  \frac{197\degree}{360 \degree}  \times \pi{r}^{2}  \\  \\ \pi{r}^{2}  =  \frac{17.8 \times 360}{197}  \\  \\ \pi{r}^{2}  =  \frac{6408}{197}  \\  \\  \pi{r}^{2}  = 32.5279188 \\  \implies \\Area\: of \: circle= 32.5279188\: yd^2 \\\\ Area \: of \: shaded \: sector \\  \\  = 32.5279188 - 17.8 \\  \\  = 14.7279188 \\  \\  \approx 14.7 \:  {yd}^{2}
