We can use the formula for the area of a triangle to solve for these dimensions.
The formula for the area of a triangle is
.
We know that the area of the triangle is 50, so here's our new equation:
How can we solve for
and
?
Well, we know how to solve equations with one variable.
And since the height is four times the base, we can replace
with
and solve for b!
And of course, since the height is four times that,
Answer:
128 cm^3
Step-by-step explanation:
Answer:
hi if you want to solve fore x and y there must be 2 equations .
Step-by-step explanation:
so that you could solve them simultaneously
-7x + 2y = 4
here 2y - 4 = 7x
( 2y -4)/7 = x
Answer:
Correct option is (A). <em>H₀</em>: = 0.5
Step-by-step explanation:
The (1 - <em>α</em>)% confidence interval for a population parameter can be used to determine whether to reject a null hypothesis or not.
The decision rule is:
If the (1 - <em>α</em>)% confidence interval for a population parameter consists of the null value of the parameter then the null hypothesis will be accepted or else it will be rejected.
A hypothesis test is performed to determine the difference between the ideal and actual heights of college males.
The 95% confidence interval for the mean difference, is:
CI = (0.8, 2.2)
The four null hypothesis provided are:
- H₀: = 0.5
- H₀: = 1.0
- H₀: = 1.5
- H₀: = 2.0
The 95% confidence interval for the mean difference consists of the value, 1.0, 1.5 and 2.0.
But it does not consist the value 0.5.
So, the null hypothesis that can be rejected is:
<em>H₀</em>: = 0.5
Thus, the correct option is (A).
Is the formula you would use.
And the answer is
or 125.66
