Answer: The mechanical advantage of the hammer is 4.

Step-by-step explanation:

We know that the mechanical advantage of the hammer is is given by the ratio between the force applied on the hammer and the force required to overcome the given force.

Force applied = 40 N

Force required= 160 N

Mechanical advantage =\frac{\text{force required}}{\text{force applied}}

Mechanical advantage =\frac{160}{40}=4

Hence, the mechanical advantage of the hammer is 4.

Mechanical Advantage = Force by Hammer / Force by Nail = 160/40 = 4

Each letter of the word "supercalifragilisticexpialidocious" is placed into a bag and drawn at 3 times, replacing the letter aft
Makovka662 [10]

Answer:

P(X ≥ 1) = 0.50

Step-by-step explanation:

Given that:

The word "supercalifragilisticexpialidocious" has 34 letters in which 'i' appears 7 times in the word.

Then; the probability of success = 7/34 = 0.20588

Using Binomial distribution to determine the probability; we have:

P(X = x)  = ^nC_x  \ \beta^x   \  (1 - \beta)^{n-x}

where;

x = 0,1,2,...n    and    0  <  β   <   1

and x represents the  number of successes.

However; since the letter is drawn thrice; the probability that the letter "i" is drawn at least once can be computed as:

P(X ≥ 1) = 1 - P(X< 1)

P(X ≥ 1) = 1 - P(X =0)

P(X \ge 1) =  1 - \bigg [ {^3C__0} (0.21)^0 (1-0.21)^{3-0} \bigg]

P(X \ge 1) =  1 - \bigg [ 1 \times 1 (0.79)^{3} \bigg]

P(X ≥ 1) = 1 - 0.50

P(X ≥ 1) = 0.50

How do u reduce 270/360 to lowest form
Ket [755]
You should simplify it using your Great Common Denominator which is 90
then, you divide each which is
270/90 out of 360/90 
which gives u 3/4 
and there goes your answer :)

Which two values of x are roots of the polynomial below 4x^2-6x+1
goblinko [34]

Step-by-step explanation:

  • Just apply the quadratic formula x=\frac{-b \left \ {{+} \atop {-}} \right. \sqrt{b^{2}-4ac}   }{2a}
  • Your equation is 4x^2-6x+1
  • Every quadratic equation follows the general form ax^2+bx+c
  • In this case a=4,b=-6,c=1
  • Substitute into the quadratic formula:
  • x=\frac{-(-6) \left \ {{+} \atop {-}} \right. \sqrt{(-6)^{2}-4(4)(1)}   }{2(4)}\\x=\frac{6 \left \ {{+} \atop {-}} \right. \sqrt{36-16}   }{8}\\x=\frac{6 \left \ {{+} \atop {-}} \right. \sqrt{20}   }{8} Now take note that the square root of any number gives a (+) and (-) result, so two different answers
  • x=\frac{6 + \sqrt{20}   }{8} ,and\\x=\frac{6 - \sqrt{20}   }{8} are the answers
