Answer: 0.71

Step-by-step explanation:

Since we have just two flavors, the probability of a cup drink being cola flavour will be calculated below:

P(R) + P(C) = 1

0.29 + P(C) = 1

P(C) = 1 - 0.29

P(C) = 0.71

Therefore, the probability of a cup drink being cola flavour is 0.71.

Answer:

Step-by-step explanation:

Length of the cuboid = ((2x + 5) cm

Width of the cuboid = (3 - x) cm

Height of the cuboid = (2x + 5) cm

Since, volume of the cuboid = Length × Width × Height

                                               = (2x + 5)(3 - x)(x + 1)

                                               = [2x(3 - x) + 5(3 - x)](x + 1)

                                               = (6x - 2x² + 15 - 5x)(x + 1)

                                               = (-2x² + x + 15)(x + 1)

                                               = x(-2x² + x + 15) + 1(-2x² + x + 15)

                                               = -2x³ + x² + 15x - 2x² + x + 15

                                               = -2x³ - x² + 16x + 15

                                               ≈ 15 + 16x - x² - 2x³

Answer:

A) 180 square feet.

Step-by-step explanation:

The two rectangles are congruent, therefore having the same area.

The area of a rectangle, or any quadrilateral for that matter, is Length x Width.

12 * 4 = 48

There are two, so multiply this number by 2 and you get 96.

The formula for a trapezoid's area is height *  1/2 * (base 1 + base 2)

The height given is 6 feet. The 1st base is 10 feet, and the longer base is 10 + 4 + 4, this equals 18

The formula is now

[tex]6 * \frac{1}{2} (18 + 10)\\6 * \frac{1}{2} (28)\\6* 14\\=84[/tex]

Now in total, 84 + 96 = 180.

B is not the answer, A is.

Answer:

112 visitors

Step-by-step explanation:

Given the prediction equation :

y = 7x + 42

x = temperature

y = number of visitors (customers)

Number of visitors when temperature is 10 degree

y = 7(10) + 42

y = 70 + 42

y = 112

Hence, the model predicts that 112 customers will visit when temperature is 10 degrees

Answer:

y = 3x

Step-by-step explanation:

Slope equation:

y2 - y1

--------

x2 - x1

----------------------------------------------------------------------------------------------------------------

         6 - 0          6

m = ----------- =   ----- = 3

         2 - 0           2

Your slope is 3.

----------------------------------------------------------------------------------------------------------------

Equation:

y = mx + b

Plug in the slope and you get:

y = 3x + b

----------------------------------------------------------------------------------------------------------------

Now to find b, you can use either coordinate point. So I will show you both ways :)

(0,0)                                                                     (2,6)

0 = 3(0) + b                                                     6 = 3(2) + b

Multiply 0 and 3                                           Multiply 2 and 3

0 = 0 + b                                                         6 = 6 + b

Subtract 0 to 0                                            Subtract 6 from 6

0 = b                                                                    0 = b

There is no y-intercept

----------------------------------------------------------------------------------------------------------------

Your answer: y = 3x

Hope this helped :)

Answer:

D

Step-by-step explanation:

6/12+8/12+9/12=23/12=1 11/12

Answer:

D. 1 11/12

Step-by-step explanation:

Let's set up our common denominator first. To do this we need to find a number divisible by 2, 3, and 4.

Multiply 3 by 4 and you'll come out with 12. 12 is divisible by 2.

Now, multiply your fractions by the numbers they need to get the denominator to 12.

1/2 x 6/6 = 6/12

2/3 x 4/4 = 8/12

3/4 x 3/3 = 9/12

Add your numerators.

6 + 8 + 9 = 23.

Your fraction should look like 23/12.

Subtract 12 from 23 and you should get 11. Because 12 equals a whole, we can go ahead and put one.

1 and 11/12.

Answer:

29 degrees

Step-by-step explanation:

Both angles are the same.

-5 -5

4x = -5y - 2

4x/4 = -5y -2/ 4

x = -5/4 y + -1/2

Answer:

98% C.I. = [-0.1270, 0.0994]

Step-by-step explanation:

Here

p1= proportion of men smokers

p1= 45/175= 0.2571

p2= proportion of women smokers

p2= 42/155= 0.2709

1)  Choose the significance level ∝= 0.02

2) The formula for confidence interval is

(p1^- p2^)- z ∝/2sqrt( p1^(1-p1^)/n1 + ( p2^(1-p2^)/n2))

and

(p1^- p2^) z ∝/2sqrt( p1^(1-p1^)/n1 + ( p2^(1-p2^)/n2))

3)  The z value is 2.05

4) Calculations:

(p1^- p2^)- z ∝/2sqrt( p1^(1-p1^)/n1 + ( p2^(1-p2^)/n2))

Putting the values

= 0.2571-0.2709)(-2.05) sqrt ( 0.2571(1-0.2571)/175+ 0.2709(1-0.2709)/155)

=-0.1270 ( using calculator)

And

(p1^- p2^)z ∝/2sqrt( p1^(1-p1^)/n1 + ( p2^(1-p2^)/n2))

Putting the values

= 0.2571-0.2709)(2.05) sqrt ( 0.2571(1-0.2571)/175+ 0.2709(1-0.2709)/155)

=0.0994  ( using calculator)

and Putting ± 2.05 in the confidence interval formula we get limits (-0.1270, 0.0994)

Answer:

[tex]g'(3)=\frac{1}{4}[/tex]

Step-by-step explanation:

There is a rule in calculus that tells us that:

[tex]g'[f(x)]=\frac{1}{f'(x)}[/tex]

In this case, we know that f(-2)=3, therefore:

g'(3)=g'(f(-2))

So, if we used the rule, we would get that:

[tex]g'[f(-2)]=\frac{1}{f'(-2)}[/tex]

we know that f'(-2)=4, so:

[tex]g'[f(-2)]=\frac{1}{4}[/tex]

or:

[tex]g'[3]=\frac{1}{4}[/tex]
