Answer:
0.96 or .96
Step-by-step explanation:
40 divided by 100 = 0.4 to change the percent to a decimal
and multiply 2.40 to 0.4, 0.4 times 2.40 is 0.96 or .96
Answer:
A. (2(4x+7x))=P
B. 2(4(3)+7(3))=2(12+21)=2(33)=66
Step-by-step explanation:
Answer:
Horizontal line which goes through the y -axis at the coordinate ( 0, C/A ).
Step-by-step explanation:
Since A is not 0 then C can not be 0 This is a logical deduction from the given formula Ay = C
The equation of any line is y = ax + b, where a is the incline and b is the intercept between the line and the y- axis.
Ay = C
Divide left and right of the = sign by A and you get:
y = C/A
This is the formula for a horizontal line which goes through the y -axis at the coordinate ( 0, C/A ).
Because it is a horizontal line it has an incline of 0.
So a = 0
y = ax + b
a = 0 and b = C/A
y = 0*x + C/A
y = 0 + C/A
y = C/A
You have three cases for a discriminant:
1. Zero
A zero in the discriminant means that there is one solution, since it's ... plus/minus zero, which is just ...
2. Negative
Negative means no real solutions, as the square root of a negative number is not real.
3. Positive
If you have a positive number within the square root, it means that your solutions will be ... plus/minus whatever the square root is. One solution is the plus, and one solution is the minus, hence two solutions.
Answer:
The point estimate for estimating the true proportion of employees who prefer that plan is 0.436
Step-by-step explanation:
A confidence interval has two bounds, a lower bound and an upper bound.
A confidence interval is symmetric, which means that the point estimate used is the mid point between these two bounds, that is, the mean of the two bounds.
In this problem, we have that:
Lower bound: 0.366
Upper bound: 0.506
Point estimate:
(0.366 + 0.506)/2 = 0.436
The point estimate for estimating the true proportion of employees who prefer that plan is 0.436
