The probability that, before the low fuel light comes on the car will travel is 0.2576

Given,

The average number of miles driven on a full tank of gas before its low fuel light comes on is ( μ )= 320

It follows the standard deviation of ( δ ) = 30

For the normal distribution,

P(X < x) = P( Z < x - μ / δ)

a)

P( X < 330) = P( Z < 330 - 320 / 30)

                   = P( Z < 0.3333)

                   = 0.6306

b)

P( X > 308) = P( Z > 308 - 320 / 30)

                  = P( Z > -0.4)

                  = P( Z < 0.4)

                  = 0.6554

c)

The value of x in the right triangle is 15√2.

A right triangle is a triangle that has one of its angles as 90 degrees.

The sides of a right triangle can be named base on the angle position. This includes hypotenuse side, opposite side and adjacent side.

Therefore, the side x of the right triangle can be found using trigonometric ratios as follows:

cos 45 = adjacent / hypotenuse

cos 45° = x / 30

cross multiply

30 cos 45° = x

Therefore,

x = 30 × 1 / √2

x =  30 / √2 × √2 / √2

x = 30√2 / 2

Answer:

mA = 69 degrees

Step-by-step explanation:

A complementary angle has a measure of 90 degrees.

(2x + 27) + (2x - 21) = 90

Simplify

4x + 6 = 90

-6

4x = 84

/4

x = 21

mA: 2(21) + 27 = 69

Answer:

A = 69°

Step-by-step explanation:

Complementary angles sum 90°

A + B = 90°

(2x + 27) + (2x-21) = 90°

4x + 27 - 21 = 90°

4x + 6 = 90°

4x = 90 - 6

4x = 84°

x = 84°/4

x = 21

Then A:

A = 2x + 27

A = 2*21  +  27

A = 42 + 27

A = 69°

B = 2x - 21

B = 2(21)  + 27

B = 42 - 21

B = 21°

Check:

69 + 21 = 90

The graph of the equation is attached to the solution.

We can graph the equation of the line by finding the x and y intercept of the line.

We know that the equation is in the slope intercept form.

Hence, we can write the y-intercept of the line as 2.

The coordinates of the point will be (0,2).

To find the x - intercept, we can put y = 0

0 = 2x + 2

-2 = 2x

x = -2/2 = -1

x = -1

The coordinates of the point will be (-1,0).

We can find another point on the line.

Let x = 1

y = 2(1) + 2

y = 2 + 2

Answer:

y = 4x - 1.5

Step-by-step explanation:

We need to find the slope (m) and the y-intercept (b), if we are writing this in the slop intercept form of a line.

y =mx + b

The slope is the change in y over the change in x.

The two points give us the y's ad x's

The y's are: -1.5 and 2.5

The x's are: 0 and 1

[tex]\frac{-1.5 - 2.5}{0-1}[/tex] = [tex]\frac{-4}{-1}[/tex] = 4  A negative divided by a negative is a positive.

We have the slope.  The slope is the point (0,b).  We are given that point.

(o, -1.5)  The y-intercept is -1.5

y =mx + b

y = 4x - 1.5

In the question ,

it is given that

the coordinates of the end points of A and B is A(-1,2) and B(5,8) .

also AC = 2/3(AB)

So , AC/AB = 2/3

and given that point C is on the line AB , hence AC+CB=AC

2+CB=3

So , CB=1

hence AC/CB = 2/1

so , the point C divides the line AB in the ration 2:1 .

and we have the coordinates of end points ,

that is x₁[tex]=[/tex] -1 , y₁=2 and x₂=5 , y₂ = 8 and the ratio m=2 and n=1 .

Substituting the above values in the section formula ,

which states that the coordinate of point C will be

((m*x₂+n*x₁)/(m+n)  ,  (m*y₂+n*y₁)/(m+n))

= ((10-1)/3 , (16+2)/3)

Number line:

The proof of (g/n)/(g/m) isomorphic to g/m from the first isomorphism theorem is as shown below.

Let a group g with normal subgroups m and n. Furthermore, n is a subset of m.

Proof: We have to prove (g/n)/(m/n) ≅ g/m           (1)

g/m and g/n are valid because m and n are normal in g. As normality satisfies the intermediate subgroup condition, n is normal in m. because normality is image-closed m/n is a normal subgroup in g/n. Under the quotient map by n, the normal subgroup m of g is sent to a normal subgroup m/n of g/n. Thus the L.H.S of the statement to prove makes sense.

To describe the isomorphism from the left side to the right side

φ: g/n \to g/m

ψ(gn) = gm

So, a coset of n is taken by the map and it gives the corresponding coset of m. This is well-defined, because if h∈ n, thus h∈ m, hence (gh)m = g(hm) = gm.

The map is a homomorphism. So we observe that it maps the identity element to the identity element, keeps group multiplication preserved, and also preserves the inverse map.

Also, the map is surjective because any coset gm is present as the image of gn under ψ.

Lastly, we need to find the kernel of the map which is given by the set of gn such that gm = m. This is those cosets of n that are in m, and this is the same as the coset space m/n. Thus the kernel of the map is exactly g/m. Thus, the surjective homomorphism ψ: g/n → g/m has kernel m/n. And now by the first isomorphism theorem

Average speed is 35.56 mph.

Calculating average speed involves dividing the whole distance travelled by the total time it took to cover that distance. Speed is the rate of movement of something at a specific time. Average speed refers to the average speed during the course of a journey.

We have to find the average speed of the whole journey.

First we have to find total distance for whole journey and then total time for whole journey.

Total distance for whole journey = 30 miles + 50 miles = 80 miles

Time for 30 miles = distance/speed = 30/40 = 3/4 hrs  = 0.75 hrs

Total time = 1.5 + 0.75 hrs = 2.25 hrs

Average speed =  total distance/ total time

= 80/2.25

= 35.56 mph.

The average speed is 35.56 mph.
