Mathematics
2 answers:
Nadusha1986 [10]3 years ago
6 0

Step-by-step explanation:

1). 35 degree

180-59=121

121+24+ m<1= 180

m<1= 35 degree

2) m<CED= 45 degree

As CED is a right angled triangle, one angle is of 90 degree while other 2 angles are of 45 degree which makes a sum of 180.

Consider the two vectors A with arrow = 3 î − ĵ and B with arrow = − î − 2 ĵ. (a) Calculate A with arrow + B with arrow 2 Correc
Verdich [7]

Answer:

Let \vec{A}=3\hat{i}-\hat{j} and \vec{B}=-\hat{i}-2\hat{j}.

a)

\vec{A}+\vec{B}=(3\hat{i}-\hat{j})+(-\hat{i}-2\hat{j})=2\hat{i}-3\hat{j}

b)

\vec{A}-\vec{B}=(3\hat{i}-\hat{j})-(-\hat{i}-2\hat{j})=4\hat{i}+\hat{j}

c) Now we calculate the direction of \vec{A}+\vec{B} and  \vec{A}-\vec{B}

We calculate the direction of \vec{A}+\vec{B} like this:

\theta=tan^{-1}(\frac{-3}{2})=-56,3^{\circ}. Since, 270\leq\theta\leq360, then the direction of \vec{A}+\vec{B} is 360^{\circ}-\theta=360^{\circ}-56.3^{\circ}=303.7^{\circ}.

Now, for \vec{A}-\vec{B}

\theta=tan^{-1}(\frac{1}{4})=14^{\circ}.

Answer/Explanation:

If the divisor is less than the reminder, then the divisor could go into the remainder meaning that the previous remainder wasn't truly the remainder.

50,000 because 8 is larger than 5 so you round up to 5 in the ten thousands place.

Consider a binomial experiment with n = 10 and p = 0.10. (a) Compute f(0). If required, round your answer to four decimal places
ss7ja [257]

Answer:

(a) The value of f (0) is 0.3487.

(b) The value of f (2) is 0.1937.

(c) The value of P (X ≤ 2) is 0.9298.

(d) The value of P (X ≥ 1) is 0.6513.

(e) The value of E (X) is 1.

(f) The value of V (X) is 0.9 and <em>σ</em> is 0.9487.

Step-by-step explanation:

The random variable <em>X</em> follows a Binomial distribution with parameter <em>n</em> = 10 and <em>p</em> = 0.10.

The probability mass function of <em>X</em> is:

P(X=x)={10\choose x}0.10^{x}(1-0.10)^{10-x};\ x=0,1,2,3...

(a)

Compute the value of <em>f</em> (0) as follows:

f (0) = P (X = 0)

       ={10\choose 0}0.10^{0}(1-0.10)^{10-0}\\=1\times 1\times 0.348678\\=0.348678\\\approx0.3487

Thus, the value of f (0) is 0.3487.

(b)

Compute the value of <em>f</em> (2) as follows:

f (2) = P (X = 2)

       ={10\choose 2}0.10^{2}(1-0.10)^{10-2}\\=45\times 0.01\times 0.43047\\=0.1937115\\\approx0.1937

Thus, the value of f (2) is 0.1937.

(c)

Compute the value of P (X ≤ 2) as follows:

P (X ≤ 2) = P (X = 0) + P (X = 1) + P (X = 2)

              =\sum\limits^{0}_{2} {{10\choose x}0.10^{x}(1-0.10)^{10-x}}\\=0.3487+0.3874+0.1937\\=0.9298

Thus, the value of P (X ≤ 2) is 0.9298.

(d)

Compute the value of P (X ≥ 1) as follows:

P (X ≥ 1) = 1 - P (X < 1)

             = 1 - P (X = 0)

             = 1 - 0.3487

             = 0.6513

Thus, the value of P (X ≥ 1) is 0.6513.

(e)

Compute the expected value of <em>X</em> as follows:

E(X)=n\times p

         =10\times 0.10\\=1

Thus, the value of E (X) is 1.

(f)

Compute the variance of <em>X</em> as follows:

V(X)=np(1-p)

         =10\times 0.10\times (1-0.10)\\=0.90

Compute the standard deviation of <em>X</em> as follows:

SD(X)=\sqrt{V(X)}

           =\sqrt{0.90}\\=0.94868\\\approx0.9487

Thus, the value of V (X) is 0.9 and <em>σ</em> is 0.9487.
