Solve for h: a = 1/2bh
h = A over 2b
h = A/b (1 /2)
h = 2Ab
h = 2A/b
Answer:
The answer is the last choice, h= 2a/b
Step-by-step explanation:
If you take the original equation, a=1/2bh, you can first divide each side of the equation by 1/2, this would give you 2a = bh. Next you would divide each side of the equation by b to solve for h. This would give you h= 2a/b, which is your final answer.

find the area of the shaded region of the large circle. give your answer to 1 decimal place.
Answer:
Step-by-step explanation:
area = [tex]\pi r^{2}[/tex]
so the area of the circle is
[tex]8^{2} \pi[/tex] which equals 64pi
BUT we have the white circles so we need to find their areas and subtract it
THE WHITE CIRCLES:
diameter = 4 so radius = 2
[tex]\pi 2^{2}[/tex] which equals [tex]4\pi[/tex]
which you double since theres TWO white circles so = [tex]8\pi[/tex]
so 64[tex]\pi -8\pi =56\pi[/tex]
[tex]56\pi =175.00[/tex]

In order to test for the significance of a regression model involving 14 independent variables and 255 observations, the numerator and denominator degrees of freedom (respectively) for the critical value of F are:_____.
a. 14 and 255.
b. 255 and 14.
c. 13 and 240.
d. 14 and 240.
Answer:
d. 14 and 240.
Step-by-step explanation:
Given that
The regression model involving 14 independent variables and 255 observations
We need to find out the numerator and denominator freedom degrees
k = 14 regression variable
= n - k - 1
= 255 - 14 - 1
= 240 residuals
df=14,240
Now The degrees of freedom for F -critical is
F_{k,n-k-1}=F_{14,240}
So, The df of the numerator is 14 and df of the denominator is 240

Find The sum of the first 10 terms 8,20,32,44
Answer:
S₁₀=620
Step-by-step explanation:
This is an arithmetic sequence with a common difference of d=12
The formula for an arithmetic series is Sₙ=(n/2)(a₁+aₙ) where aₙ is the nth term and a₁ is the first term.
We know that a₁=8 and d=12 where the 10th term would be a₁₀=8+(10-1)12=116.
Therefore, the sum of the first 10 terms of the arithmetic series is S₁₀=(10/2)(8+116)=(5)(124)=620
the wheel on the tv program wheel of fortune is first divided equally into 24 compartments with one labeled"lose a turn" find the probability that the wheel stops a "lose turn" for each of the following a.single spinb.two successive spins c. three successive spins (complete solution)
Answer:
a) [tex]\frac{1}{24}[/tex] probability that the wheel stops a "lose turn" for a single spin.
b) [tex]\frac{1}{576}[/tex] probability that the wheel stops a "lose turn" for two successive spins.
c) [tex]\frac{1}{13824}[/tex] probability that the wheel stops a "lose turn" for three successive spins.
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
24 components on the wheel, one of which is "lose a turn"
This means that each time the wheel stops, there is a [tex]\frac{1}{24}[/tex] probability that it stops at lose a turn.
a.single spin
Only one spin, so:
[tex](\frac{1}{24})^1 = \frac{1}{24}[/tex]
[tex]\frac{1}{24}[/tex] probability that the wheel stops a "lose turn" for a single spin.
b.two successive spins
Two spins, so:
[tex](\frac{1}{24})^2 = \frac{1}{576}[/tex]
[tex]\frac{1}{576}[/tex] probability that the wheel stops a "lose turn" for two successive spins.
c. three successive spins
Three spins, so:
[tex](\frac{1}{24})^3 = \frac{1}{13824}[/tex]
[tex]\frac{1}{13824}[/tex] probability that the wheel stops a "lose turn" for three successive spins.

The component form of a vector is (-7.765,28.978) What is the direction angle for the vector measured counterclockwise from the positive x-axis?
Answer:
The direction angle for the vector measured clockwise from the positive x-axis is approximately 105.001°.
Step-by-step explanation:
Let be [tex]P(x,y)[/tex] a point containing the components of a vector, the direction angle for the vector regarding origin ([tex]\theta[/tex]), in sexagesimal degrees, is determined by the following formula:
[tex]\theta = \tan^{-1} \frac{y}{x}[/tex] (1)
Where:
[tex]x[/tex] - x-coordinate of the point P.
[tex]y[/tex] - y-coordinate of the point P.
Let consider that [tex]P(x,y) = (-7.765, 28.978)[/tex]. After a quick inspection, we note that vector stands in the 2nd Quadrant ([tex]x < 0 , y > 0[/tex]). Then, the direction of the angle with respect to the positive x semiaxis is:
[tex]\theta = \tan ^{-1} \left(\frac{28.978}{-7.765} \right)[/tex]
[tex]\theta \approx 105.001^{\circ}[/tex]
The direction angle for the vector measured clockwise from the positive x-axis is approximately 105.001°.
Angle the given vector makes with the positive x-axis when measured counterclockwise is required.
The direction of the angle for the vector measured counterclockwise from the positive x-axis is 105°. The calculations have been shown below by using the concepts of vector.
VectorsThe given vector is (-7.765,28.978)
The angle is found by the formula
[tex]\theta=\tan^{-1}\dfrac{y}{x}[/tex]
Here,
y = 28.978
x = -7.765
Substituting the given values we get
[tex]\theta=\tan^{-1}\dfrac{28.978}{-7.765}=-74.99=-75^{\circ}[/tex]
So, the required angle is
[tex]180-75=105^{\circ}[/tex]

Step-by-step explanation:
You can simplify the 20 inside of the radical by finding its prime factors. 20 has 3 prime factors: 5, 2, and 2. Since the 2 occurs twice, we can cancel out those 2s in the 20 itself and put a singular 2 outside of the radical. It is essentially turning [tex]\sqrt{20}[/tex] into 2[tex]\sqrt{5}[/tex]. Since we now have simplified that 20, the entire equation is now 4x[tex]\sqrt{5x^2^0}[/tex]. We can root x^20 to get x^10, and [tex]\sqrt{5}[/tex] stays that way. The entire equation is now 4x[tex]\sqrt{5}[/tex]x^10, which can be simplified to [tex]4x^1^1\sqrt{5}[/tex].

a. Is there sufficient evidence to conclude that there is a linear correlation between the two variables?
b. Is there sufficient evidence to conclude that there is a linear correlation the two variables?
Answer:
Since the calculated t= 7.8120 falls in the critical region ≥ 2.306 we reject H0 and conclude that there is a linear correlation between the two variables.
Step-by-step explanation:
We see that r²= 0.981 and r= 0.995 from the figure .
The P- value is less than 0.05 which indicates that the two variables are linearly correlated.
Set up the hypothesis as
H0: β= 0 i.e the two variables X and Y are not related
Ha: β≠0 i.e the two variables are related
The significance Level is set at ∝=0.05
The test statistic , if H0 is true is
t= b/sb
where sb² = s²yx / ∑( x-x`)² = ∑( y-y`)²/n-2 ∑( x-x`)²
assuming that the distribution of Yi for each Xi is normal with the same mean and the same standard deviation , the statistic t conforms to the Student's t distribution with n-2= 8 degrees of freedom
(X - x`)2 (X - x`)(Y - y`) (Y - y`)2

7174.09 6953.87 -82.1²=6740.41

4998.49 5380.27 -76.1²=5791.21
1069.29 1016.97 -31.1=967.21

3102.49 3124.77 -56.1²=3147.21
SS: 32646.1 SP: 32797.3 33,586.9
Sum of X = 3877
Sum of Y = 3991
Mean X = 387.7
Mean Y = 399.1
Sum of squares (SSX) = 32646.1
Sum of products (SP) = 32797.3
b = SP/SSX = 32797.3/32646.1 = 1.00463
a = Y` - bX `= 399.1 - (1*387.7) = 9.60437
Syx= √∑(y-y`)²/n-2= 33,586.9/8= 4198.3625
sb= syx/ √∑(x-x`)²=4198.3625/32646.1 =0.12860
Putting the values in the regression equation
ŷ = bX + a
ŷ = 1.00463X + 9.60437
The critical region is t ≥ t (0.025) (8)= 2.306
t= b/ sb= 1.00463/ 0.12860=7.8120
Since the calculated t= 7.8120 falls in the critical region ≥ 2.306 we reject H0 and conclude that there is a linear correlation between the two variables.
