A company has determined that its weekly profit is a function of the number of items that it sells. Which equation could represent the weekly profit in thousands of dollars, y, when the company sells x items?

Answer:

Width = 64.4 feet

Step-by-step explanation:

A scale is a representative faction that can be used to either increase or decrease the dimension of a given object.

scale = [tex]\frac{nem length}{actual length}[/tex]

But,

1 feet = 12 inches

For the actual MetroPass;

length = 3.4 inches = 0.2033 feet

width = 2.1 inches = 0.175 feet

The MetroPass float has a length of 74.8 feet.

scale = [tex]\frac{74.8}{0.2033}[/tex]

         = 367.93

So that;

the width of the MetroPass float = 0.175 x 367.93

                               = 64.388

Therefore, the width of the MetroPass float is 64.4 feet.

Answer:

A (0,3) (-3,-3)

Step-by-step explanation:

A graph will match the equation if both the coordinates points replaced in the equation generate a identity.

When x = -3

[tex]y + 3 = 2(x + 3)[/tex]

[tex]y + 3 = 2(-3 + 3)[/tex]

[tex]y + 3 = 0[/tex]

[tex]y = -3[/tex]

So (-3,-3) is part of the graph.

When x = 0

[tex]y + 3 = 2(x + 3)[/tex]

[tex]y + 3 = 2(0 + 3)[/tex]

[tex]y + 3 = 6[/tex]

[tex]y = 3[/tex]

So (0,3) is part of the solution.

(-3,-3) and (0,3), so option A.

c. The test statistic for a hypothesis test has a t distribution

Explanation:

The test statistic when the standard deviation is known and population is normally distributed should not have a t-distribution. A t-distribution will be required for the test statistic for the hypothesis if standard deviation is unknown and population is also normally distributed. The other options are correct however.

Explanation:

Convert each percentage to decimal form

Then multiply the decimal values

0.30*0.60 = 0.18

That converts to 18%

So there's an 18% chance that both events happen at the same time. In other words, there's an 18% chance of the temperature falling below zero and the bus being late.

The solution of the logarithmic function log₂₇165  found using logarithmic properties is :

(1 + log ₃55)/3.

What is a logarithmic function?

The logarithm is exponentiation's opposite function in mathematics. This indicates that the exponent to which b must be raised in order to obtain a number x is the logarithm of x to the base b. The usage of logarithmic functions makes it simple to determine some of the non-integral exponent values. The common logarithmic function, which has a base of 10, is identified by the symbols log₁₀ or log.

We are asked to solve the following logarithmic function.

 log₂₇165

Here the base of the log is 27.

According to logarithmic properties, we can write the above functions as:

 log₂₇165  = log 165 /  log 27

If we are dividing the numerator and denominator by log 3, then the new base will become 3.

(log 165 / log 3) / (log 27/log3) = log ₃165 / log₃ 27

Now we can solve as follows,

log ₃165 / log₃ 27 = log ₃(3*55) / log₃ (3³) = [log ₃(3)+log ₃(55)] / 3log₃3

                                          = (1 + log ₃55)/3

Therefore the solution of the logarithmic function log₂₇165  is

(1 + log ₃55)/3.

Step 1: Define

Identify

x = -75.9

y = 2.6

-xy

Step 2: Evaluate

If for example, you were given y = 2(x-3)^2 + 5, then the vertex is (3,5)

As another example, the equation y = 7(x+1)^2 + 10 has the vertex (-1,10)

The general vertex form is y = a(x-h)^2 + k with the vertex (h,k)

Answer:

(-h,k)

Step-by-step explanation:

vertex form:

y＝a(x-h)^2+k

switch sign of h and you get the x

keep sign of k and you get y

ex- 3(x-5)+7

vertex＝（5,7）

Answer:

Step-by-step explanation:

We know that h must be a negative number. In this case, h is equal to -14.

Answer:

N'(9, -1)

Step-by-step explanation:

Transformation is the movement of a point from its initial location to a new location. Types of transformation include translation, reflection, rotation and dilation.

Reflection is the flipping of an object over the line of reflection. If the point A(x, y) is reflected over the line x = a, the y coordinate would remain but the x coordinate will change.

The vertices of figure KLMN are K(−2, −1), L(−2, −3), M(−5, −3), and N(−5, −1). If figure KLMN is reflected across the line x = 2, the new points would be at:

K'(6, -1), L'(6, -3), M'(9, -3) and N'(9, -1)

Answer:

The angles of an equilateral triangle are the same and is 60°. Therefore it is acute ( < 90°)

Answer:

[tex]f(x) = -5(x+1)^2[/tex]

Step-by-step explanation:

We are given the following function:

[tex]f(x) = x^2[/tex]

Shift 1 unit right.

Shifting a function a units to the right is finding f(x+a). So

To shift one unit right:

[tex](x+1)^2[/tex]

Vertically stretch by a factor of 5.

To vertically stretch by a factor of 5, we multiply the function by 5. So

[tex]5(x+1)^2[/tex]

Reflect over the x-axis.

To reflect over the x-axis we multiply the function by -1. So

[tex]f(x) = -5(x+1)^2[/tex]

Ok.

You predicted that your tip will be $200.

You realised that you were wrong by less than 10%.

So,

10% of $200

= (10/100) × $200

= $20

So, your actual tip can be less or more by less than $20.

$160 (less than $200 by $40, so error = 20%)

$180 (less than $200 by $20, so error = 10%)

$200 (equal to $200, so error = 0%)

$220 (more than $200 by $20, so error = 10%)

$240 (more than $200 by $40, so error = 20%)

So, your possible actual tips can be:

$200 (equal to $200, so error = 0%)

Answer: The value to add to the set is 52

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

For a moment, ignore the extra value we'll add in later.

The given set of values add to -34.

Let x be the extra value we add in. It adds to the -34 to get -34+x, then we divide by 6 because the set {-4,-10,-16,8,-12,x} has 6 items.

So we get the mean (-34+x)/6

Set this equal to the mean we want (3) and solve for x

(-34+x)/6 = 3

-34+x = 6*3

-34+x = 18

x = 18+34

x = 52

The set {-4,-10,-16,8,-12,x} updates to {-4,-10,-16,8,-12,52} and this set has a mean of 3.

Answer:

5196

Step-by-step explanation:

So it's 5040+(-156)

We have to find the absolute value

|-156|=156

5040+156=5196

Answer:

5196 m

Step-by-step explanation:

The sea is level = 0

If Punack Jaya, is 5040 m above sea level then it would be = + 5040 m

If Lake Assal is 156 m below sea level then it would be = - 156 m

The difference between the two elevations:

= 5040 - (-156)

= 5040 + 156 --> two negatives create a positive

= 5196 m

Answer:

$133.2

Step-by-step explanation:

[tex]\frac{120*2*5.5}{100\\}[/tex]=13.2

13.2+120

133.2

The simple interest of$13.2  is due on loan of $120 for two years with the annual rate of 5.5%.

simple interest is the interest amount for a particular principal amount of money at some rate of interest.

S.I = (P × R × T)/100

Where,

S.I is simple interest

P is the Principal amount

R is the interest rate

T is time in years

According to the given question.

We have

Principal, P = $120

Interest rate, R = 5.5%

And time, T = 2 years

Therefore, the simple interest for two years for the amount $120 is given by

[tex]S.I = \frac{(120)(5.5)(2)}{100}[/tex]

⇒ [tex]S.I = \frac{1320}{100}[/tex]

⇒ S.I = $13.2

Hence, the simple interest of$13.2  is due on loan of $120 for two years with the annual rate of 5.5%.
