Answer:

0.6

Step-by-step explanation:

4/7 can be considered a suspended division problem.  To find the answer, 4 must be divided by 7.  This yields the result 0.57142, which can be rounded to 0.6.

Step-by-step explanation:

The way i like to remember it is that the exponent inside of the radical will be the numerator of the fraction and the index of the radical will be the denominator so the answer is 2^(-5/3).

Answer:

A) 0.386

B).0.325

Step-by-step explanation:

probability p will not work = 0.15

Q probability w5ill work = 0.85

Number of flashlight = 3

Probabilty of at least one=

1- probability of none

But probability of none= 3C0(p)^0(q)^3

= 1*(0.15)^0(0.85)^3

= 1*1*(0.614)

= 0.614

Probability of at least one=1-0.614

= 0.386

Probability of two flashlight work

= 3C1(0.15)^1(0.85)^2

= 3*(0.15)*(0.7225)

= 0.325

The solution to [tex]3x\:-\:1\ge 12[/tex] is [tex]x\ge \frac{13}{3}[/tex].

Step-by-step explanation:

An inequality is a mathematical relationship between two expressions and is represented using one of the following symbols: inequalities involving "<", "≠" or ">" are referred to as "strict inequalities", while inequalities involving "≤" or "≥" are not.

Solving an inequality means finding all of its solutions. A solution of an inequality is a number which when substituted for the variable makes the inequality a true statement.

Answer:

The speed of light moving along the shoreline when it is 1 km from P is 2.1064 km

Step-by-step explanation:

We are given that a point 1 km from point P on the shoreline would  form a a right triangle with the lighthouse, point P, and the point 1 km from  point P.

The distance from that point to the lighthouse would be the hypotenuse.

That would also be the radius of the circle the beam of light is making at that point.

To find the hypotenuse

[tex]Hypotenuse^2 = Perpendicular^2 +base^2 \\r^2 = 1^2 +2^2\\r=\sqrt{1^2+2^2}\\r=2.236[/tex]

Circumference =[tex]2 \pi r = 2 \times 3.14 \times 2.236=14.05 km[/tex]

The beam of light is making at point 14.05 km away

One revolution: [tex]\frac{60}{9}= 6.67[/tex] sec per revolution

Speed = [tex]\frac{14.05}{6.67}=2.1064[/tex]

Hence The speed of light moving along the shoreline when it is 1 km from P is 2.1064 km

Answer:

44.70 USD

Step-by-step explanation:

250÷1.3687

=182.655074158

182.655074158-150

=32.655074158

32.655074158×1.3687

=44.6950000001

The 44.70 US dollars Phelan now has if Phelan exchanged 250 US dollars for euros option (A) is correct.

It is defined as the conversion from one quantity unit to another quantity unit followed by the process of division, and multiplication by a conversion factor.

It is given that:

While traveling to Europe, Phelan exchanged 250 US dollars for euros. He spent 150 euros on his trip.

After returning to the United States he converts his money back to US dollars. H

Let x be the total original 250 US dollars Phelan now have:

The value of x can be found as follows:

x = (250/1.3687 - 150)x1.3687

After simplification:

x = 44.69 ≈ 44.70 US dollars

Thus, the 44.70 US dollars Phelan now has if Phelan exchanged 250 US dollars for euros option (A) is correct.

The requried equations that are equivalent to each other are,
(A)  2 + x = 5    (B) x + 1 = 4   (E) -5 + x = -2.

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

Given equations,
(A) 2 + x = 5
Simplifying the above expression,

x = 5 - 2
x = 3

Similarly, simplify all the equations,
(B) x = 3
(C) x = -3
(D) x = 11
(E) x = 3

Therefore, equations that give x = 3, after simplification is equivalent equations.

Answer:

5.37% probability that a bulb picked at random from this company product will have a life time of at least 300 hours

Step-by-step explanation:

Problems of normally distributed samples are solved using the z-score formula.

In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

In this question, we have that:

[tex]\mu = 210, \sigma = 56[/tex]

What is the probability that a bulb picked at random from this company product will have a life time of at least 300 hours?

This is 1 subtracted by the pvalue of Z when X = 300. So

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{300 - 210}{56}[/tex]

[tex]Z = 1.61[/tex]

[tex]Z = 1.61[/tex] has a pvalue of 0.9463

1 - 0.9463 = 0.0537

5.37% probability that a bulb picked at random from this company product will have a life time of at least 300 hours

Answer:

1/5x = h(x)

Step-by-step explanation:

6x+y = 4x+ 11y

Subtract y from each side

6x+y -y = 4x+ 11y-y

6x = 4x+10y

Subtract 4x from each side

6x-4x = 4x+10y-4x

2x = 10y

Divide each side by 10

2x/10 = 10y/10

1/5x = y

1/5x = h(x)

Answer:

fifth angle = 102°

Step-by-step explanation:

A pentagon is a polygon that have 5 sides. A pentagon can be divided into 3 triangles .And the sum of angle in a triangle is 180°. Therefore the sum of interior angle in a pentagon will  be 180 × 3 = 540°. The sum of interior angles of a pentagon = 540°.

The general rule for calculating sum of the interior angles of a polygon is

sum of interior angle = (n−2) × 180°

where

n = number of sides

n = 5 since we are dealing with a  pentagon.

sum of interior  angle of a pentagon = 540°

The fifth angle can be computed when you subtract the sum of the 4 angles from 540°.

fifth angle = 540 - (88 + 118 + 132 + 100)

fifth angle = 540 - 438

fifth angle = 102°
