The value of b is 61°.
you solve by doing this:
add up the two given angles, 58° and 61° to get 119°. then you subtract from 180° to get 61.
Answer:
0.4
Step-by-step explanation:
Given
60 % wear neither ring nor a necklace
20 % wear a ring
30 % wear necklace
This question can be Solved by using Venn diagram
If one person is choosen randomly among the given student the probability that this student is wearing a ring or necklace is


The sum of probabilty is equal to 1 because it completes the set
Therefore the required probabilty is 0.4
Answer:
x - intercepts are (-7,0) and (-2,0)
A is the correct option.
Step-by-step explanation:
We have been given the equation of the parabola 
For x- intercept, y = 0

We can split the middle term as 9x = 7x +2x

Now take GCF

Factored out the common term

Apply the zero product property

Solve for x

Hence, x - intercepts are (-7,0) and (-2,0)
A is the correct option.
You replace the y with f(x)
So it becomes f(x)=2x+1
The radical function is 3√x + 1.
Since the cubic root of zero is zero, 0 would be x.
Add zero and one, which gives you 1. 1 is y.
You get (0,1)
Since this is a positive radical, it would be going to the top right.
So, the domain is x ≥ 0
the range is y ≥ 1
