Suppose you have a right triangle with congruent legs and a hypotenuse that measure (12√5)/5. What is the length of the smaller leg? Round to the nearest hundredth
Answer:
5.4 is the length
Step-by-step explanation:
5.333 - (12√5)/5 - round to nearest hundreth (5.4)
length total 5.4
Thanks and Rate my Answer Please!
The length of the smaller leg is 3.8 unit.
What is Pythagoras theorem?Pythagoras theorem states that "the sum of the areas of the two squares on the legs (a and b) equals the area of the square on the hypotenuse (c)" i.e.
[tex]c^{2} = a^{2} + b^{2}[/tex]
Let the length of the leg be b and a.
According to the given question.
We have a rigth triangle which have congruent legs.
And hypotenuse, c = [tex]\frac{12\sqrt{5} }{5}[/tex]
Since, the legs are congruent.
Therefore,
a = b
Now, according to the Pythagoras theorem.
[tex]c^{2} = a^{2} + b^{2}[/tex]
[tex]\implies c^{2} = a^{2} + a^{2}[/tex]
[tex]\implies c^{2} = 2a^{2}[/tex]
[tex]\implies (\frac{12\sqrt{5} }{5} )^{2} = 2a^{2}[/tex]
[tex]\implies \frac{144\times 5}{25} = 2a^{2}[/tex]
[tex]\implies \frac{144}{5} = 2a^{2}[/tex]
[tex]\implies \frac{72}{5} = a^{2}[/tex]
[tex]\implies a = \sqrt{\frac{74}{5} }[/tex]
[tex]\implies a = \sqrt{14.8}[/tex]
[tex]\implies a = 3.84[/tex]
[tex]\implies a = 3.8[/tex] unit
Hence, the length of the smaller leg is 3.8 unit.

A certain type of legal proceeding has three possible outcomes: in favor of party A, in favor of party B, or not in favor of either party. The outcomes are expected to be 40 percent, 20 percent, and 40 percent, respectively. A random sample of 40 cases is selected from a certain judge to investigate whether the judgeâs outcomes are consistent with the expected outcomes. A chi-square goodness-of-fit test is conducted, and the value of the chi-square test statistic is Ï2=9.19 with a corresponding pâvalue of 0.01. Assuming the conditions for inference were met, which of the following is the correct interpretation of the pâvalue?
a. There is a 1 percent chance that the company's claim is correct.
b. If the null hypothesis is true, there is a 1 percent chance that the company's claim is correct.
c. If the null hypothesis is true, there is a 1 percent chance of obtaining a chi-square value of 9.19.
d. If the null hypothesis is true, there is a 1 percent chance of obtaining a chi-square value of at least 9.19.
e. There is a 1 percent chance of obtaining a chi-square value of at least 9.19.
The basically it tells us the chances of the claim being true
If we assume the null hypothesis is correct.
What is the method of chi-square test?The Chi-Square Test of Independence determines whether there is an association between categorical variables.
We have given that,
The outcomes are expected to be 40 percent, 20 percent, and 40 percent, respectively.
If the null hypothesis is true, there is a 1 percent chance that the company’s claim is correct.
The p-value tells us the likeliness of our data occurring under the null hypothesis.
Therefore ,basically it tells us the chances of the claim being true

Answer:
(-10,0)
Step-by-step explanation:
y = 3/2 x + 15
To find the x intercept let y =0 and solve for x
0 = 3/2x +15
Subtract 15 from each side
-15 = 3/2x -15+15
-15 = 3/2x
Multiply each side by 2/3
2/3 *-15 = 2/3 * 3/2x
-10 =x
The x intercept is

Explain how to find the area of the composite figure above in your explanation be sure to include the formulas you will need to solve the problem
9514 1404 393
Answer:
40.5 square inches
Step-by-step explanation:
The figure appears to be a trapezoid with bases 15 inches and 12 inches, and a height of 3 inches. The formula for the area of a trapezoid is useful in this case:
A = 1/2(b1 +b2)h
A = (1/2)(15 in +12 in)(3 in) = (1/2)(27 in)(3 in) = 40.5 in²
The area of the composite figure is 40.5 square inches.
__
Additional comment
You get the same answer if you divide the figure into a rectangle and a triangle. The rectangle is 3 in high by 12 in long, so has an area of ...
A = bh = (12 in)(3 h) = 36 in²
The triangle has a base of (15 -12) = 3 in, and a height of 3 in. It has an area of ...
A = 1/2bh = 1/2(3 in)(3 in) = 4.5 in²
Then the total area is the sum of the rectangle and triangle areas:
figure area = 36 in² +4.5 in² = 40.5 in²
