Required data table is attached below :
Answer:
D. The fewest students prefer black Model A1 calculators.
Step-by-step explanation:
From the data Given :
Larger proportion of students prefer White calculators(0.65) to black calculators (0.35)
Also, Fewer proportion of students like black model C3 (0.20) than white model A1 (0.40)
Also, the proportion of students who like model C3 calculators(0.30) are fewer than those who prefer the model A1 (0.45)
Therefore, the true inference which can be derived from the data is, the least preferred calculator is the Black model A1 calculator with a proportion of 0.05
If u can plz give more information I am more than glad to help out
Answer:
x=5 x=3
Step-by-step explanation:
x^2 – 8x + 15
What two numbers multiply to 15 and add to -8
-5*-3 = 15
-5 +-3 = -8
(x-5) (x-3) =0
Using the zero product property
x-5 =0 x-3 =0
x=5 x=3
For this triangle in particular, we can use the special rules of a 30-60-90 triangle
This says:
The opposite side of 30° is: x
The opposite side of 60° is: x * sqrt(3)
The opposite side of the 90° is: 2x
We have our side length for 90° so we just have to work backwards
To find our 30° side length we must divide by 2
8/2 = 4
Which means your y = 4
Now that we have our 30° side length we can just multiple it by sqrt(3)
That means your x = 4 sqrt(3)
