Answer:
A cos C = 12/13
Step-by-step explanation:
cos theta = adjacent side/ hypotenuse
cos C = BC/AC
But we don't know BC, but we can find it using the Pythagorean theorem
a^2 +b^2 = c^2
5^2 +BC^2 = 13^2
25 + BC ^2 =169
Subtract 25 from each side
BC^2 = 169-25
BC ^2 = 144
Taking the square root of each side
BC =12
cos C = 12/13
First you need to find how many grams is 1 ounce. 1o z.is 28.35 g, then you need to multiply 28.35 g by 5 which is 141.75. you need to round it to the nearest hundred so it is about 142 grams.
the key here would be
1 oz. = 28.35g or 1 oz. = 28 g

The mean for the second week increased by $0.40.
The mean for the first week is found by adding the data points and dividing by 5:
(12.99+10.50+9.89+6.90+7.58)/5 = $9.57
Since the cost increased by $2 the second week, we add two to the data points before dividing by 5:
(12.99+10.50+9.89+6.90+7.58+2)/5 = $9.97
To find the increase in means, subtract them:
9.97-9.57 = $0.40.
