Answer:
There is no valid value for b
Step-by-step explanation:
We solve the above question using the law of cosines
b² = a² + c² - 2ac × Cos B
B = 42°, a = 6, c = 4
b² = 6² + 4² - 2 × 6 × 4 × Cos 42
b =√6² + 4² - 2 × 6 × 4 × Cos 42
b = √36 + 16 - 48 × Cos 42
Solving the above question, there is no valid value for b
-2k - (-7)k
= -2k + 7k
= 5k
-7(p + 2) + 9(p - 4)
= -7p - 14 + 9p - 36
= 2p - 50
5 cubed ( or an exponent of three )
Answer:
B. 1.70
Step-by-step explanation:
Given:


Substituting the given values into the formula to find the test statistic z:

First let's just combine the shelves to make it easier. 99 + 99 = 198.
We can simply divide 198 by 11/16 to get the answer. First let's convert 11/16 to a decimal.
11 divided by 16 is 0.6875
So 198 divided by 0.6875 is 288.
288 novels can fit on both the shelves.
