Answer:

15 minutes and 52 seconds

Step-by-step explanation:

Well you jsut gotta subtract the two times

I would put them liek this

1:39:4

-1:23:12

Since the last part is un doable just add the minute into the seconds and take off a minute

1:38:64

-1:23:12

You’d get if solved correctly, 15 minutes and 52 seconds

Answer:

4(ax + 3) -3ax = 25 + 3

4ax + 12 - 3ax = 25 + 3

4ax - 3ax + 12 = 28

1ax + 12 = 28

1ax = 28 - 12

ax = 16

a = 16/x

x = 16/a

Hey there!

4 (ax + 3) - 3ax = 25 + 3

4ax + 12 - 3ax = 28

4ax - 3ax = 28 - 12

ax = 16.

Solving for 'a'

ax = 16

a = 16/x

Solving for 'b'

ax = 16

x = 16/a

Answer:

d

Step-by-step explanation:

Answer:

Step-by-step explanation:

So we'll take the ratio of  3:8  to mean  3 to 8   ,  which is 11 total parts.

since we know that part, and we can see that the x coordinate goes from -15 to 7, which is a total  of 22  and that y goes from 18 to 7, which is a total of 11 then we know that  we can just break up each into their 3:8 ratios

3:8=11 for the y component

6:16=22 for the x component

so subtract 3 from the B point for the y or add 3 to the A point , either works here,   Let's go from B so y = 10 (7+3)  and x = 1  (7-6)

So a point at (1,10) will be on the line and at a ratio of 3:8  :)

Answer:

The 85% confidence interval for the mean number of dresses purchased each year is (6.1, 6.3).

Step-by-step explanation:

We have that to find our [tex]\alpha[/tex] level, that is the subtraction of 1 by the confidence interval divided by 2. So:

[tex]\alpha = \frac{1 - 0.85}{2} = 0.075[/tex]

Now, we have to find z in the Ztable as such z has a pvalue of [tex]1 - \alpha[/tex].

That is z with a pvalue of [tex]1 - 0.075 = 0.925[/tex], so Z = 1.44.

Now, find the margin of error M as such

[tex]M = z\frac{\sigma}{\sqrt{n}}[/tex]

In which [tex]\sigma[/tex] is the standard deviation of the population and n is the size of the sample.

[tex]M = 1.44\frac{1.1}{\sqrt{208}} = 0.1[/tex]

The lower end of the interval is the sample mean subtracted by M. So it is 6.2 - 0.1 = 6.1

The upper end of the interval is the sample mean added to M. So it is 6.2 + 0.1 = 6.3

The 85% confidence interval for the mean number of dresses purchased each year is (6.1, 6.3).

Answer:

sin(3π/7 - 2π/21)

Step-by-step explanation:

Given

sin 3π /7 cos 2π/ 21 − cos 3π/ 7 sin 2π/ 21

Required

Write a trigonometry formula for the expression

Using sine formula, we have:

sin(A - B) = sinAcosB - cosAsinB

The above formula can be applied to the given expression where

A = 3π/7

B = 2π/21

So, the trigonometry formula is:

sin 3π /7 cos 2π/ 21 − cos 3π/ 7 sin 2π/ 21= sin(3π/7 - 2π/21)

Answer:

sin(π/3), exact value √3/2

Step-by-step explanation:

21 divided by 7 is 3, 3 - 2= 1, 1 is = π

Answer:

[tex]75; 85; 95; 105[/tex]

Step-by-step explanation:

Given

[tex]Angles: x, x + 10, x + 20, x + 30[/tex]

Required

Find the angles

Angles in a [tex]quadrilateral \add\ up\ to\ 360[/tex]

So:

[tex]x+ x + 10+ x + 20+ x + 30 = 360[/tex]

Collect like terms

[tex]x+ x + x + x = 360 - 10 - 20 - 30[/tex]

[tex]4x = 300[/tex]

Solve for x

[tex]x = \frac{300}{4}[/tex]

[tex]x = 75[/tex]

So, the angles are:

[tex]x = 75[/tex]

[tex]x +10= 75 + 10 = 85[/tex]

[tex]x +20= 75 + 20 = 95[/tex]

[tex]x +30= 75 + 30 = 105[/tex]

50-x=30

-x=30-50

-x=-20

x=20

Answer:

No, x=9 it's not the right solution.

Step-by-step explanation:

Because :if x=9 the equation would be like 50-x=41 and not 30.

But in these case it's like :50-x=30

                                          50-30=20 and not 9.

Answer:

A

Step-by-step explanation:

(0.5a, 0.5a) is the midpoint of the line BD and a is the value that belongs in the green box.

The midpoint of a line segment is a point that lies exactly halfway between two points.

Consider the points B(0,a) and D(a,0).

The general form of midpoint formula is given by

Midpoint = ( (x₁ + x₂)/2 , (y₁ + y₂)/2)

Here, x₁ = 0, x₂=a and y₁ = a, y₂ = 0

Therefore, the value that belongs in the green box is given by

(x₁ + x₂)/2 = (0+a)/2 = a/2 = 0.5a

(y₁ + y₂)/2 = (a+0)/2 = a/2 = 0.5a

The midpoint is given by

Midpoint = ( (x₁ + x₂)/2 , (y₁ + y₂)/2) = (0.5a, 0.5a)

Hence, the value that belongs in the green box is a and the midpoint of the line BD is (0.5a, 0.5a).

Answer:

Shortest Path : A-C, C-Z

Shortest possible time = 143

Step-by-step explanation:

P.S - The exact question is -

Given -

T1 = 38

T2 = 52

T3 = 63

T4 = 67

T5 = 91

T6 = 62

T7 = 64

To find - What is the shortest path and what is the shortest possible time to travel from A to Z ?

Proof -

Choices for shortest path is -

Choice 1 : A-B, B-E, E-Z ;

Choice 2 : A-C, C-Z ;

Choice 3 : A-B, B-D, D-Z

Now,

For Choice 1 : A-B, B-E, E-Z

Distance between A-B = T1 = 38

Distance between B-E = T4 = 67

Distance between E-Z = T7 = 64

So,

The distance = 38 + 67 + 64 = 169

Now,

For Choice 2 : A-C, C-Z

Distance between A-C = T2 = 52

Distance between C-Z = T5 = 91

So,

The distance = 52 + 91 = 143

Now,

For Choice 3 : A-B, B-D, D-Z

Distance between A-B = T1 = 38

Distance between B-D = T3 = 63

Distance between D-Z = T6 = 62

So,

The distance = 38 + 63 + 62 = 163

∴ By comparing we get

Shortest Path = A-C, C-Z

Shortest possible time = 143

The shortest path is A→C→Z and the shortest possible time is 143 units option second is correct.

It is given that the traveler is trying to determine the fastest way to travel from city A to city Z.

It is required to find the shortest path and the shortest possible time to travel from A to Z.

It is defined as the path in which all the sum of the path will be shortest in a weighted diagram known as the shortest path.

We have the time required to travel from A to B is T1 = 38 units

Similarly, for the path A to C is T2= 52 units

For the path B to D is T3= 63 units

For the path B to E is T4 = 67 units

For the path C to Z is T5 = 91 units

For the path D to Z is T6 = 62 units

For the path E to Z is T7 = 64 units

For the path A→B→E→Z

The total time required = T1+T4+T7

                                       = 38+67+64 ⇒169 units.

For the path A→C→Z

The total time required = T2+T5

                                       = 52+91 ⇒143 units.

For the path A→B→D→Z

The total time required = T1+T3+T6

                                       = 38+63+62 ⇒ 163 units.

Thus, the shortest path is A→C→Z and the shortest possible time is 143 units option seconds is correct.
