Answers

Answer:

a₄ = 12

Step-by-step explanation:

To obtain the terms in the sequence add 2 to the previous term, that is

a₂ = a₁ + 2 = 6 + 2 = 8

a₃ = a₂ + 2 = 8 + 2 = 10

a₄ = a₃ + 2 = 10 + 2 = 12

Mrs. Franklin's kitchen is shaped like a rectangle. She has a scale drawing of her kitchen with dimensions 7 inches and 5 inches.

The scale of the drawing is 1/2 inch = 1 foot.

What is the perimeter of Mrs. Franklin's actual kitchen?

Answers

Answer:

48 feet

Step-by-step explanation:

7 inches = 14 feet

There are 14 halves in 7 inches.

5 inches = 10 feet

There are 10 halves in 5 inches

14+14+10+10=48

The perimeter is 48 feet

. A man has the choice of running either a host-snack stall or an ice-cream stall at a sea side resort during the summer season. If it is a fairly cool summer, he should make Rs. 5000 by running the hot-snack stall, but if the summer is quite hot, he can only expect to make Rs. 1000. On the other hand, if he operates the ice-cream stall, his profit is estimated at Rs. 6500, if the summer is hot, but only Rs. 1000 if it is cool. There is a 40 per cent chance of the summer being hot. Should he opt for running the hot-snack stall or the ice-cream stall. Give mathematical argument.

Answers

Answer:

The investment cost from ice cream is significantly smaller than the hot dog shop, the man could perhaps opt for something like a hot dog stall.

Step-by-step explanation:

The given values are:

Percentage of being hot summer,

= 40%  

i.e,

= 0.4

So that,

The percentage of being cold,

= 1 - 0.4

= 60%

Now,

From hot dog, the expected profit will be:

⇒ [tex]5000\times P(cold \ summer) + 1000\times P(hot \ summer)[/tex]

On putting the values, we get

⇒ [tex]5000\times 0.6+1000\times 0.4[/tex]

⇒ [tex]3400[/tex]

From ice-cream stall, the profit will be:

⇒ [tex]6500\times P(hot \ summer)+1000\times P(cold \ summer)[/tex]

On putting the values, we get

⇒ [tex]6500\times 0.4+1000\times 0.6[/tex]

⇒ [tex]3200[/tex]

So the above is the right response.

To start if a total of 13 people got a ticket then we know that

x+y=13

x and y being explained in the problem

then if adult tickets are $40 and children tickets are $20 and the total cost is 360 we can set up the next equation

40x+20y=360

If you were to plug in 1 lets say into x that means that 1 person bought a ticket for $40 this shown by 40 (1) this is the same premise for the childrens tickets.

now we have

x+y=13

40x+20y=360

now we can solve by eliminating one of the variables this is done by either getting rid of the x or y and solving for the other. I solved for the y value first this looks like

-40(x+y=13)

40x+20y=360

Distribute the -40 to each value

giving you

-40x-40y=-520

40x+20y=360

add these together from the top down

the x's cancel leaving

-20y=-160

then isolate the y value by dividing both sides by -20

-20y/-20=-160/-20

leaving you with your y point

y=8

This is how many childrens rickets were sold now we can plug into the first linear equation

x+8=13

now easy subtration to isolate the x point

x+8-8=13-8

x=5

Finally leaving you with point (5,8)

the answer is point (5, 8)

A bottling company uses a filling machine to fill plastic bottles with cola. The bottles are supposed are supposed to contain 300m.

Show your work. (b) What is the probability that the mean contents of six randomly chosen bottles is less than 295 mL? Show your work.

Answers

Answer:

0.15866 ; 0.0071627

Step-by-step explanation:

Given that:

Mean (m) = 298

Standard deviation (s) = 3

A.) P(x < 295)

Using the relation to obtain the standardized score (Z) :

Z = (x - m) / s

Z = (295 - 298) / 3 = - 1

p(Z < - 1) = 0.15866 ( Z probability calculator)

B.)

Z = (x - m) / s /sqrt(n)

Z = (295 - 298) / 3/sqrt(6) = −2.449489

p(Z < - 2.449) = 0.0071627 ( Z probability calculator)

The probability will be:(a) 0.15866(b) 0.007163

Given values are:

Mean,

m = 298

Standard deviation,

s = 3

(a)

P(x < 295)

The standardized score will be:

→ [tex]Z = \frac{(x-m)}{s}[/tex]

By substituting the values, we get

      [tex]= \frac{(295-298)}{3}[/tex]

      [tex]= \frac{-3}{3}[/tex]

      [tex]= -1[/tex]

Now,

By using the Z probability calculator, we get

→ [tex]p(Z< -1) = 0.15866[/tex]

(b)

The standardized score will be:

→ [tex]Z = \frac{x-m}{\frac{s}{\sqrt{n} } }[/tex]

By putting the values,

      [tex]= \frac{295-298}{\frac{3}{\sqrt{6} } }[/tex]

      [tex]= -2.449489[/tex]

Now,

→ [tex]p(Z < -2.449)= 0.007163[/tex]

Thus the responses above are correct.

What is the length of the hypotenuse?
C =
yards

Answers

C = 10 yards because hypotenuse formula is a^2 + b^2 = c^2

Answer:

The length of the hypotenuse is 10 yards.

Step-by-step explanation:

Given that this is a right triangle, you could apply the Pythagorean Theorem to it. Although I'm not exactly sure, given as there's no indication in your question.

The Pythagorean Theorem is a^2 + b^2 = c^2, for context.

So, 6^2 + 8^2 = ?^2.

6^2 = 36

8^2 = 64

64 + 36 = 100

However, 100 isn't the side length of c, it's c squared. To "unsquare" it, you need to find the square root of it.

In this case, the square root of 100 is 10.

6^2 + 8^2 = 10^2. Makes sense, right?

36   + 64  = 100

Hope this helps.
