Answer:

Step-by-step explanation:

Total outcomes = 6

Favourable outcomes = 0(As there is no 7 in a dice)

Probability = Favourable Outcome/Total outcomes

=> 0/6

=> 0

Rewrite the function by completing the square. f(x)= x^{2} + x -30f(x)=x 2 +x−30f, left parenthesis, x, right parenthesis, equal

Verizon [17]

Answer:

$f(x)= (x+\frac{1}{2} )^{2}-30\frac{1}{4}$

Step-by-step explanation:

$f(x)= x^{2} + x -30$

To re-write the function by completing the square, the procedure is to first

(i)take the coefficient of x

(ii)Divide it by 2 and Square it

Coefficient of x=1

Divided by 2 = 1/2

Square of 1/2 = $(\frac{1}{2} )^{2}$

Next, we add it to the function and subtract same so that the equation remains balanced

$f(x)= x^{2} + x +(\frac{1}{2} )^{2}-(\frac{1}{2} )^{2}-30$

Pick each of the squared term and square the sum

$f(x)= (x+\frac{1}{2} )^{2}-(\frac{1}{2} )^{2}-30$

$f(x)= (x+\frac{1}{2} )^{2}-30\frac{1}{4}$

The tires on a new compact car have a diameter of 2.0 ft and are warranted for 63,000 miles. (a) Determine the angle (in radians

Damm [24]

Answer:

Tire will be warranted for $3.326\times 10^8radian$

Step-by-step explanation:

We have given that tire is warranted for 63000 miles

We know that 1 mile = 5180 feet

So $63000miles=63000\times 5280=3.3264\times 10^8feet$

Diameter is given d = 2 feet

So radius $r=\frac{d}{2}=1feet$

Angular distance is given by $\Theta =\frac{linear\ distance}{radius}=\frac{3.326\times 10^8}{1}=3.326\times 10^8radian$

Use the given values of n and p to find the minimum usual value μ - 2σ and the maximum usual value μ + 2σ. Round your answer to

fenix001 [56]

Given Information:

number of trials = n = 1042

Probability of success = p = 0.80

Required Information:

Maximum usual value = μ + 2σ = ?

Minimum usual value = μ - 2σ = ?

Answer:

Maximum usual value = 859.51

Minimum usual value = 807.78

Step-by-step explanation:

In a binomial distribution, the mean μ is given by

μ = np

μ = 1042*0.80

μ = 833.6

The standard deviation is given by

σ = √np(1 - p)

σ = √1042*0.80(1 - 0.80)

σ = √833.6(0.20)

σ = 12.91

The Maximum and Minimum usual values are

μ + 2σ = 833.6 + 2*12.91

μ + 2σ = 833.6 + 25.82

μ + 2σ = 859.51

μ - 2σ = 833.6 - 25.82

μ - 2σ = 807.78

Therefore, the minimum usual value is 807.78 and maximum usual value is 859.51
