Which graph best represents an exponential function?
• A.
B.
C.

=========================================================

Explanation:

The process of finding the arithmetic mean involves two steps

The first bit of info your teacher gave you is "the mean of five numbers in a set is 12". While we don't know the actual individual values themselves, we know that they must add to some variable y. Dividing y over n gets us the mean

y/n = mean

y/5 = 12

y = 5*12

y = 60

The five values add to 60.

----------

The next bit of info is that "the mean of all six is 14". That allows us to say:

(sum of all 6 values)/6 = mean

(sum of all 6 values)/6 = 14

( (sum of 5 values) + (6th value) )/6 = 14

(y + x)/6 = 14

(60 + x)/6 = 14

where x is the 6th number we want to find.

-----------

Solve for x

(60 + x)/6 = 14

60+x = 6*14

60+x = 84

x = 84-60

x = 24 so choice (1) is the answer

Answer:

a. θ = 6t

b. 1.048 minutes

c. y = 54sin(6t)

Step-by-step explanation:

diameter d = 108 foot

distance above the ground = 58 feet

a.) expression to represent number of radians

radian = 6 rad/min

θ = wt

w = 6

θ = 6t

t is in minutes

b.) we are to find the time period for one full revolution

time period = 2π/6

π = 22/7

[tex]T=\frac{2(22/7)}{6}[/tex]

= 1.048 minutes

c. Expression showing Justins height above the ground

y = rsinθ -----(1)

θ = wt = 6t

we find the radius r

diameter = 2 * radius

108 = 2r

r = 108/2

= 54 foot

we put these values in the equation 1 above

y = 54sin(6t)

Answer:

In an isosceles triangle, 2 of the angles are identical

Sum of the 3 angles of a triangle is always 180

Possibility 1 - 50 is one of the 2 identical angles

The 3 angles will be 50, 50, (180-50-50)

Possibility 2 - 50 is not one of the 2 identical angles

The 3 angles will be 50, (180-50)/2, (180-50)/2

You can work out the above and see which answer is not the possible angle

Please let me know if you have further questions.

Answer:

D

Step-by-step explanation:

In an isosceles triangle two angles are equal to each other, single two sides are congruent. Since the sides of a triangle add up to 180, we can figure out possible answers. This means it could either be

50, 50 and 80

Or 50, 65, 65

Which means the impossible measure would be D 130.

Answer:

th answer is 7:15 pm

Step-by-step explanation:

basically just count with your hands if you want, start with one finger and say 13 and go up from there, 7th finger is the 19th. Thats my easiest way of doing it. Or you can subtract 24-19 and subtract 12 from the remaining sum

Answer:

moderate positive relationship

Step-by-step explanation:

From the data:

The linear relationship between score and rating can be obtained by calculating the Pearson correlation Coefficient between the two variables. This can be obtained more easily by using technology, a linear correlation Coefficient calculator. The result of the correlation Coefficient for the data above is about 0.66. This value is positive which shows that the association between the variables is positive, increase in one leads to increase in the other and vice versa. Also the value shows that the relationship is fairly strong.

Answer:

y = 0.75x + 35

Step-by-step explanation:

y = 0.75x + 35

where: y for cost in $, x for number of stickers ordered

Cost Price= CP= $1.80

Discounted Price = $ 1.53

Amount Saved= $ 0.27

Discount= 15%

The Discounted Price $ 1.53 is obtained after the discount percent applied to the cost price and subtracted from the cost price.

When the discounted price is subtracted from the Cost Price we get the amount saved.

Discount = discount % × Cost Price

Discount = 15% × $ 1.80 = $ 0.27

Discounted Price= Cost Price- Discount

                         = $1.8- $ 0.27= $ 1.53

Answer:

[tex](x -1)^2 + (y+1)^2 = 0.25[/tex]

Step-by-step explanation:

Given

The attached graph

Required

The equation of the circle

The equation of a circle is:

[tex](x - h)^2 + (y - k)^2 = r^2[/tex]

Where

[tex](h,k) \to center[/tex]

[tex]r \to radius[/tex]

From the attached graph,

[tex](h,k) = (1,-1)[/tex]

[tex]r = 0.5[/tex]

So, we have:

[tex](x - h)^2 + (y - k)^2 = r^2[/tex]

[tex](x -1)^2 + (y--1)^2 = 0.5^2[/tex]

[tex](x -1)^2 + (y+1)^2 = 0.5^2[/tex]

[tex](x -1)^2 + (y+1)^2 = 0.25[/tex]

Answer:

There are 36 boys in the class.

Step-by-step explanation:

This question is solved by a system of equations.

I am going to say that:

x is the number of boys

y is the number of girls.

There are 42 pupils in a class.

This means that [tex]x + y = 42[/tex].

Since we want x, we have that [tex]y = 42 - x[/tex]

12 of them are Malays while the rest are Chinese. 1/4 of the boys and 1/2 of the girls are Malay.

This means that:

[tex]\frac{x}{4} + \frac{y}{2} = 12[/tex]

Since [tex]y = 42 - x[/tex]

[tex]\frac{x}{4} + \frac{42 - x}{2} = 12[/tex]

Multiplying everything by 4.

[tex]x + 84 - 2x = 48[/tex]

[tex]-x = -36[/tex]

[tex]x = 36[/tex]

There are 36 boys in the class.

Answer:

0.0006

Step-by-step explanation:

The probability is

Given that

A denotes the bottle being filled improperly

And,  

B denotes the label on the bottle will not be affixed properly

So,

P(A) = 0.02 ,

ANd, P(B) = 0.03

Also that A and B are independent events.

So, by property of independence is

P(A \cap B) = P(A and B) = P(A) P(B)

= P(A and B) =P(A)P(B)

= 0.02 × 0.03

= 0.0006

Answer:

Option 2: -¾

Step-by-step explanation:

First identify 2 points on the line.

(0, 1), (4, -2)

Substitute the coordinates into the gradient formula below:

[tex]\boxed{gradient = \frac{y1 - y2}{x1 - x2} }[/tex]

☆ (x₁, y₁) is the 1st coordinate and (x₂, y₂) is the 2nd coordinate.

Slope of the line

[tex] = \frac{1 - ( - 2)}{0 - 4} [/tex]

[tex] = \frac{1 + 2}{ - 4} [/tex]

[tex] = - \frac{3}{4} [/tex]

☆ Since the line is sloping downwards looking from the left to right, the line must have a negative slope.

Answer:

2(x + 5) = 2x + 10

Step-by-step explanation:

2(x + A) = 2x + 10

2x + 2A = 2x + 10

Equating constant terms on both sides :

2A = 10

A = 5

Therefore , 2(x + 5) = 2x + 10
