Answer: 10.72\ cm

Step-by-step explanation:

Given

Radius of circle r=14\ cm

Length of chord is l=18\ cm

Suppose the distance between the chord and center is x

From figure, we can write

\Rightarrow r^2=x^2+9^2\\\Rightarrow 14^2=x^2+9^2\\\Rightarrow x^2=196-81\\\Rightarrow x^2=115\\\Rightarrow x=\sqrt{115}\\\Rightarrow x=10.72\ cm

When painting my bedroom I used 3 1/2 liters of blue paint and 2 1/4 liters of red paint. How much paint did I use in all
Lubov Fominskaja [6]
Hi there!

To solve this problem, we need to find the total amount of paint used by adding the two fractions.

First, we need to find the common denominators below adding.

1/2 = 2/4
1/4 = 1/4

The common denominator is 4.

Now, we add the mixed numbers together:

3 2/4 + 2 1/4 = 5 3/4

Since 5 3/4 can't be simplified, the answer is:

5 3/4 liters of paint

Hope this helps!

Phonics is an instructional method in which children are taught to connect sounds with letters or groups of letters. A sample of
Fantom [35]

Answer:

A 90% confidence interval for the mean number of letter sounds identified in one minute is: (30.84, 37.34).

Step-by-step explanation:

We have that to find our \alpha level, that is the subtraction of 1 by the confidence interval divided by 2. So:

\alpha = \frac{1 - 0.9}{2} = 0.05

Now, we have to find z in the Ztable as such z has a pvalue of 1 - \alpha.

That is z with a pvalue of 1 - 0.05 = 0.95, so Z = 1.645.

Now, find the margin of error M as such

M = z\frac{\sigma}{\sqrt{n}}

In which \sigma is the standard deviation of the population and n is the size of the sample.

M = 1.645\frac{23.44}{\sqrt{141}}

M = 3.25

The lower end of the interval is the sample mean subtracted by M. So it is 34.09 - 3.25 = 30.84.

The upper end of the interval is the sample mean added to M. So it is 34.09 + 3.25 = 37.34.

A 90% confidence interval for the mean number of letter sounds identified in one minute is: (30.84, 37.34).
