Answer:

GIVE BRAINLEST PLZ :)

a) 3

b) 24

Step-by-step explanation:

Two right angle triangles that share two lines have a common angle.

Because of this the ratio of dimensions will remain the same, since this inner angle cannot change

This means we can look at the ratio of the lengths (questions calls it widths)

convention is to go from big to small.  The easiest way is to use the large side and divide by the small

RATIO :  =

With this ratio we can convert a small dimension into the relative big one.

W = w * R = 8 * 3 = 24m

EXTRA: Easyier way is to just realize the ratio of both dims must be equal

\frac{w}{l}  = \frac{W}{L}  => \frac{8}{10}  = \frac{W}{30}\\Rearrange and solve :)

19810 rounded to the nearest hundred
Cloud [144]
19,810 rounded to the nearest hundred is 19,800.
8 is in the hundreds place, and the number 1 is in front of it.
 
Numbers 1-4 in front of the number make the number stay the same.

Numbers 5-9 in front of the number make the numbers round up one number.

Lucky Charms are sold in boxes with an advertised mean weight of 20.5 oz. The standard deviation is known to be 2.25 oz. A consu
Alinara [238K]

Answer:

Set of hypothesis.

Step-by-step explanation:

We are given the following in the question:

Population mean, μ =  20.5 oz

Sample mean, \bar{x} = 20.4 oz

Sample size, n = 50

Population standard deviation, σ =  2.25 oz

First, we design the null and the alternate hypothesis

H_{0}: \mu = 20.5\text{ oz}\\H_A: \mu < 20.5\text{ oz}

We use One-tailed z test(left tailed) to perform this hypothesis.

Formula:

z_{stat} = \displaystyle\frac{\bar{x} - \mu}{\frac{\sigma}{\sqrt{n}} }

Putting all the values, we have

z_{stat} = \displaystyle\frac{20.4 - 20.5}{\frac{2.25}{\sqrt{50}} } = -0.3142

Based on the significance level, we can make our decision and complete the hypothesis testing.

We may accept the null hypothesis or fail to accept depending on different significance level.
