Answer:

Answer:

50.2

Step-by-step explanation:

$ut = \sqrt{ {6}^{2} + {5}^{2} } \\ \sqrt{36 + 25} \\ \sqrt{61 } \\ using \: cosine \: rule \\ cos \: u = \frac{ {5}^{2} + 61 - 36 }{2 \times 5 \times \sqrt{61} } \\ \\ = \frac{25 + 61 - 36}{78} \\ \\ = \frac{50}{78 } \\ \cos \: u = 0.64 \\ m \:u = 50.2$

Gwent pour 256 milliliters of water in to Ravi Henry pours 189 milliters of water in to Ravis .Ravis now contains 800 Milliters

Contact [7]

Answer:

Ravi had 355ml water to begin with.

Step-by-step explanation:

Given that,

amount of water that Gwent pour in Ravi = 256 ml

amount of water that Henry pour in Ravi = 189 ml

amount of water after each have poured = 800 ml

suppose amount of water ravi had before both poured water in it = x

Equation

256 + 189 + x = 800

445 + x = 800

x = 355ml

Initially ravi had 335ml of water.

Question Help A manufacturer ships toasters in cartons of 1010. In each carton, they estimate a 1010% chance that any one of t

natta225 [31]

Answer:

The probability that there will be repair exactly 3 toaster is 0.0574.

Step-by-step explanation:

Binomial Distribution:

A discrete random variable X having the set {0,1,2,3......,n} as the spectrum, is said have a binomial distribution with parameter n= number of trials and p=probability of number of success on an individual trial, if the p.m.f (probability mass function) of X given by,

$P(X=x)=C(n,x)p^x(1-p)^{n-x}$ x=0,1,2,......,n

=0 elsewhere

where 0<p<1 and n is a positive integer.

Total number of toaster in cartons(n) = 10.

Probability of number of success on an individual trial p= 10% = 0.10

$\therefore P(X=3)= C(10,3)(0.10)^3(1-0.10)^{10-3}$

$=\frac{10!}{3!(10-3)!}(0.10)^3)(0.90)^7$

=0.0574

The probability that there will be repair exactly 3 toaster is 0.0574.

Find the absolute value of 1 and - 1

AlekseyPX

The absolute value of BOTH of those numbers is ' 1 '.

==========================================

Oh ! Wait just a second. Did you mean for the 1 and the -1 to be combined
in some way ? If that's what you had in mind, then you'll have to be more
specific. "And" is no mathematical operation that I know of.
