Answer:
Step-by-step explanation:
Arc length of the circle is given by,
Arc length = 
Area of the sector of a circle =
22). Arc length of the circle having central angle = 
= 60°
Arc length = 
= 
= 7.33 cm
23). Arc length of the circle having central angle = 225°
Arc length = 
= 12.5π
= 39.27 km
24). Central angle = 
= 
= 225°
Area of the sector = 
= 43.20 yd²
25). Area of the sector = 
= 65.97 yd²
I think the answer may be C
Hi!
To solve this, we need to know how much the earrings and necklace cost together, then we need to know if it's more or less than how much she has ($20)
So first, add the costs together.
7 . 5 8
+ 1 3 . 3 6
---------------
2 0 . 9 4
The necklace and earrings cost $20.94 which is more than $20.
The answer is no, Doreen does not have enough money.
Hope this helps! :)

The test statistics and the p-value from the research sampling will be 1.57 and 0.119.
<h3>What is test statistic?</h3>
It should be noted that a test statistic simply means a number that's used to describe how the observed value is far from the null hypothesis.
In this case, the test statistics is 1.57. The p value will be:
= 2 × 0.0593
= 0.119
Therefore, the test statistics and the p-value from the research sampling will be 1.57 and 0.119.
