Statistics is not an exact science, meaning that with any answer, there will be variance. This is because the sample size used to obtain values is always smaller than the population being studied.
Answer:
1/2
Step-by-step explanation:
In PEMDAS, there is no parentheses in this equation, so we move on to exponents.
-5^2 is 25
Now, we divide -15/-3 then we get 5
Next, we do -3+20=17
25+5+17 would be 47
Your answer should be 47!
Hope this helps (:
She has more than enough because with 8 cups you only need 2 quarts. She has 3 which gives her 12 cups.
The complete question in the attached figure
we know that
the triangle ACB is an isosceles triangle
AC=AB----------> equals to the radius
so
∡ACB=∡CBA
the angle ∡CAB is equals to 54° by central angle
so
180°=54°+2*∡CBA--------> ∡CBA=[180-54]/2-----> 63°
∡CBA=63°
∡DBC=∡CBA-----------> ∡DBC=63°
the answer is∡DBC=63°
