Answer:
x=3
Step-by-step explanation:
1) 10x+1-1 = 12x-5-1, this becomes a new equation
Equation: 10x = 12x-6
2) 10x-12x = 12x-12x-6, this become a new equation
Equation: -2x = -6
3) Divide both sides by -2: -2x/2 = -6/2
4) Once you simplify, you will get x=3
Hope this helps!
a. No, simply because 20 isn't divisible by 3 without having a decimal, and there must be a whole number because there's no such thing as half of a species.
b. The answer would be the remainder of the fraction ²/<span>₅</span>
Area of triangle = 0.5 * base * height
30 = 0.5 * 6 * base
30 = 3 * base
so , base = 10 inch
Answer:
The range of values likely to contain the true value of the population parameter is between 44% and 52%.
Step-by-step explanation:
Confidence interval concepts:
A confidence interval has two bounds, a lower bound and an upper bound.
These bounds are dependent of the sample mean and of the margin of error.
The lower bound is the sample mean subtracted by the margin of error, while the upper bound is the margin of error added to the sample mean.
The confidence interval is likely to contain the true value of the population parameter.
In this question:
Sample mean: 48%
Margin of error: 4%
48 - 4 = 44%
48 + 4 = 52%
The range of values likely to contain the true value of the population parameter is between 44% and 52%.
This is an equation representing the ellipse
Explanation:
- The general equation for an ellipse is
so, when you simplify it according to the characteristics of a and b, you would end up in the similar form of the equation given
- where a represents half the length of the major axis and b represents half the length of the minor axis.
- The easiest method to identify, look at whether both the variables are squared, and also the coefficient of x and y should be positive but different.
