Answer:

There is a pattern with the ratios of corresponding sides. You can see that the measurement of each side of the first triangle divided by two is the measure of the corresponding side of the second triangle. Use patterns like this to problem solve the length of missing sides of similar triangles.

The formula to convert °C to °F is:

PolarNik [594]

Answer:

80.6

Step-by-step explanation:

F = 9/5 C + 32

F = (9/5)*27 + 32 Substitute 27 into the equation

F = 243 / 5 + 32 Multiply 9 and 27 together

F = 48.6 + 32 Divide by 5

F = 80.6 Add on 32

A very quick way to do this is to double your centigrade temperature and and 30 which you should be able to do in your head.

2*27 = 54 Add 30

54 + 30 = 84

This quick way will tell you if you get near the right answer.

Answer:

The 95% confidence interval $81.852 < \mu < 280.098$

Step-by-step explanation:

From the question we are told that

The sample mean is $\= x = 180.975$

The standard deviation is $\sigma = 143.042$

The sample size is n = 8

Given that the confidence level is 95% then the level of significance is

$\alpha =( 100- 95) \%$

=> $\alpha =0.05$

Generally from the normal distribution table the critical value of $\frac{\alpha }{2}$ is

$Z_{\frac{\alpha }{2} } = 1.96$

Generally the margin of error is mathematically represented as

$E = Z_{\frac{\alpha }{2} } * \frac{\sigma }{\sqrt{n} }$

=> $E = 1.96 * \frac{ 143.042 }{\sqrt{8} }$

=> $E = 99.123$

Generally 95% confidence interval is mathematically represented as

$\= x -E < \mu < \=x +E$

=> $180.975 -99.123 < p < 180.975 +99.123$

=> $81.852 < \mu < 280.098$
