Answer:

0.210 ; 0.790

Step-by-step explanation:

Given that:

Percentage of correct completion by technician = 21%

Percentage of minor error = 70%

Major error in chemical measurement of sample = 9%

A.) probability that a randomly selected technician completes preparation without error:

This is equal to the percentage of correct completion by technicians :

P(correct completion) = 21% = 0.210

B.) probability that it is completed with either a minor or major error :

P(completion with minor error) + P(completion with major error)

= 70% + 9%

= 0.70 + 0.09

= 0.790

Answer:

97

Step-by-step explanation:

I used the law of cosines:  [tex]t^{2} =s^{2} +u^{2} -2tu cos (t)[/tex]

Let plug the numbers in :  t^2=[tex]13^{2} +84^{2} -2(13)(84)cos (165)[/tex] which approx is 97 to the nearest inch.

The length of 't' is approximately 69 inches.

To find the length of t, we can use the Law of Cosines, which states that for any triangle with sides a, b, and c and opposite angles A, B, and C, respectively:

a²= b² + c² - 2bc cos(A)

In this case, we want to find the length of t, which is opposite to the given angle ∠T. We know that:

u = 84 inches (opposite to angle ∠U)

s = 13 inches (opposite to angle ∠S)

∠T = 165°

Let's substitute these values into the Law of Cosines:

t² = u²+ s²- 2us cos(T)

t²= (84)²+ (13)² - 2(84)(13) cos(165°)

t²= 7,056 + 169 - 2(84)(13)(cos(180°-15°))

t²= 7,225 - 2(84)(13)(cos(15°))

t²= 7,225 - 2(84)(13)(0.9659)

t²= 7,225 - 2,485.68

t² = 4,739.32

t ≈ 68.86

Rounding to the nearest inch, the length of t is approximately 69 inches.

Step-by-step explanation:

just not photosynthesis or gravity so it has to be plasma

also:

The aurora borealis (northern lights) form when charged particles emitted from the sun during a solar flare penetrate the earth's magnetic shield and collide with atoms and molecules in our atmosphere.

and

Because it consists of charged particles, plasma can conduct electricity and respond to a magnetic field.

Answer:

The car is 10 miles from parking lot.

Step-by-step explanation:

Given that:

The car travels 6 miles north and 8 miles east.

This forms the two legs of a right angled triangle.

The distance from car to parking lot will be hypotenuse.

Using Pythagorean theorem;

[tex]a^2+b^2=c^2\\(6)^2+(8)^2= c^2\\c^2 = 36 + 64 \\c^2 = 100[/tex]

Taking square root on both sides

[tex]\sqrt{c^2}=\sqrt{100}\\c=10[/tex]

Hence,

The car is 10 miles from parking lot.

Answer:

y=3x

Step-by-step explanation:

The equation of a line can be written as 'y=mx+b', where 'm' is the slope, 'b' is a number, and 'x' and 'y' represent the 'x' and 'y' co-ordinates of any point on the line.

To find the slope m, take two points (x₁,y₁) and (x₂,y₂) and use the formula

m= (y₂-y₁)/(x₂-x₁)

Our points are (1,3) and (2,6):

(6-3)/(2-1)=3/1=3

Now that we have found the slope, we can write the equation as

y=3x+b

To find b, sub in a point:

9=3(3)+b

9=9+b

b=0

So our equation is y=3x

Answer:

[tex]x^2+(y+1)^2=2[/tex]

Step-by-step explanation:

We use the formula for a circle with center at (0, -1), that goes through the (x, y) point (-1, -2):

[tex](x-0)^2 + (y-(-1))^2 = R^2\\Using \,\,\,point\,\,\,(-1, -2)\\(-1-0)^2+ (-2+1)^2 = 1 + 1 = 2 = R^2[/tex]

Therefore, the equation of this circle can be written as:

[tex]x^2+(y+1)^2=2[/tex]

Answer:

21 yards

Step-by-step explanation:

There will be 21 yards in 63 feet of the measurement.

Expression in maths is defined as the relation of numbers variables and functions by using mathematical signs like addition, subtraction, multiplication and division.

Given that one yard is equal to three feet. There are 63 feet of measurement.

The value of 63 feet in yards will be calculated as:-

1 yard = 3 feet

1 feet = 1 / 3  yards

63 feet = ( 63 / 3 ) yards

63 feet = 21 yards

Therefore, there are 21 yards in 63 feet of the measurement.
