The length of the hypotenuse of a right triangle is 145 units. The length of one leg of the triangle is144 units. Mike wrote the

following step to find the length of the unknown leg: Length of the unknown leg = 1452 − 1442 = 21,025 − 20,736 = 289 units Which statement best explains whether Mike's step is correct or incorrect? (5 points)
It is incorrect because the length of the unknown side is the square root of 289. It is incorrect because the length of the unknown side is the square root of 41,761.
It is correct because the length of the unknown side is the difference of the lengths of the sides.

Answer:

Option A.

Step-by-step explanation:

The length of the hypotenuse of a right angle 145 units.

The length of one leg of the triangle can be measured by Pythagoras theorem.

other leg = \sqrt{(Hypotenuse)^{2}-(oneleg)^{2}}

               = \sqrt{(145)^{2}-(144)^{2} } = \sqrt{21025-20736}

               = \sqrt{289}

Therefore, option A is the correct option because the other leg should be  \sqrt{289}.

What are the factors of the square root of 329
Andru [333]

Answer: x=-\dfrac{3}{2}, 7

Step-by-step explanation:

2x^2-10x-26=x-5

2x^2-10x-26-x+5=0  Move all terms to one side

2x^2-11x-21=0 Simplify 2{x}^{2}-10x-26-x+5

2x^2+3x-14x-21=0 Split the second term

x(2x+3)-7(2x+3)=0  Factor out common terms in the first two terms, then in the last two terms.

(2x+3)(x-7)=0 Factor out the common term 2x+3

x=-\dfrac{3}{2}, 7

Today Carly’s bank account contains $96. Yesterday she made a withdrawal of $33. What was the bank account balance before Carly
Artist 52 [7]
96 plus 33 equals 129

so the answer is $129 because she has 96 dollars now but if you add the amount of money she took out to the amount she had before then you will get the amount of money before the withdrawal

Use the given probability value to determine whether the sample results could easily occur by​ chance, then form a conclusion. A
Wittaler [7]

Answer:

It appears that there ▼ is is not sufficient evidence to conclude that pregnant women can correctly predict the gender of their baby.

Step-by-step explanation:

The results occur by chance.

There's not enough evidence to show that the pregnant women can predict the gender of the babies. 0.327 probability of getting such sample results by chance means 1-0.325 = 0.675 women are unable to predict the gender.

This 0.675 tells us that more than 67 % of the women are unable to predict the gender.

The other option  is  incorrect .

The probability shows that the sample results ▼ could not have easily occurred by chance.

The probability does not show how the sample results are affected by chance. There' s no increase in the number of trials , there's no evidence of how they guessed.
