Answer:

144 inches

Step-by-step explanation:

If they are moving at the same speed and start at the same time, they have to go the same distance

That means they will meet in the middle

If they are 72 inches from the right side that means the middle is 72 inches from the right side

The road is 2 times 72 inches

2*72 = 144

Answer:

1.Random circumstance: Color of traffic light when Robin approaches the main intersection. Possible outcomes: Traffic light is green when Robin arrives, or Traffic light is not green when Robin arrives.

2.Random circumstance: Song on the radio when first turned on. Possible outcomes: Robin's favorite song is playing, or Robin's favorite song is not playing.

4.Random circumstance: Nearest available parking space. Possible outcomes: Robin finds an empty parking space in front of the building, or Robin does not find an empty parking space in front of the building.

Step-by-step explanation:

A random circumstance is one whose outcome cannot be predicted because we either do not have the full details of the matter or it has not been confirmed yet by a reliable source. In the short description of events provided above;

1.The color of the traffic light is unpredictable because it is not under the control of the drivers but is automated.

2. Robin's favorite song playing on the radio is a random circumstance because she has no control over what song is played. So, she might as well have tuned in and it would be her least favorite song playing.

3. Robin driving into the office and finding the parking space empty is a random circumstance because it is not predictable. She might have come in and found the entire space filled.

Answer:

The answer to your question is given below.

Step-by-step explanation:

To know the correct answer to the question, do the following:

√12 + √108

= 12^½ + 108^½

= 4^½ • 3^½ + 36^½ • 3^½

Factorise

3^½ (4^½ + 36^½)

Recall:

4^½ = √4 = 2

36^½ = √36 = 6

Therefore,

3^½ (4^½ + 36^½) = 3^½ (2 + 6)

= 3^½ • 8

Answer:

-1, 0, -1

f(x)=-1(x+0)^2-1

Step-by-step explanation:

vertex translated from (0,0) to (0,-1), so the function translated down by -1

f(x)=a(x-0)^2 -1

substitute (1,-2) to solve a,

a(1-0)^2 -1 = a-1 = -2

a=-1

thus, f(x)=-1 (x+0)^2 -1

Subtract the difference:

14,649 - 2389 = 12,260

Divide that by 2

12,260 / 2 = 6,130

That is the number of shows for B.

For A add the 2,389 to the number of shows for B

2389 + 6130 = 8,519

Show A = 8,519

Show B = 6,130

Answer:

14,649 - 2389 = 12,260

Divide that by 2

12,260 / 2 = 6,130

That is the number of shows for B.

For A add the 2,389 to the number of shows for B

2389 + 6130 = 8,519

Show A = 8,519

Show B = 6,130

-20 and -7 are in circle A, but outside circle B

0, 9, 81 are in circle B

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

Explanation:

The set of whole numbers is

{0, 1, 2, 3, 4, ...}

While the set of integers is

{ ..., -3, -2, -1, 0, 1, 2, 3, ... }

The difference is that integers involves negative numbers.

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

The upper left corner is incorrect because the "0" should be in set B since 0 is also a whole number. The lower left corner is also ruled out because of this reason.

The upper right corner (choice H) is incorrect as well because 10 and 46 are whole numbers also, so they belong in set B which is a better description/place for them.

So basically the numbers 0,1,2,3,... go in circle B. The negatives of those values will go in circle A, but outside circle B. Only choice J describes this kind of situation.

Step-by-step explanation:

For a quadrilateral to be rhombus the diagonals have to be perpendicular bisectors of each other.

Answer:

Step-by-step explanation:

Given that:

The numbers of the possible public swimming pools are 5

From past results, we have 0.007 probability of finding bacteria in a public swimming area.

In the public swimming pool, the probability of not finding bacteria = 1 - 0.007

= 0.993

Thus;

Probability of combined   =  Probability that at least one public

sample with bacteria           swimming area have bacteria

Probability of combined sample with bacteria  = 1 - P(none out of 5 has          

                                                                                bacteria)

Probability of combined sample with bacteria = 1 - (0.993)⁵        

= 1 - 0.9655

= 0.0345

Thus, the probability that the combined sample from five public swimming areas will show the presence of bacteria is 0.0345

From above, the probability that the combined sample shows the presence of bacteria is 0.0345 which is lesser than 0.05.

Thus, we can conclude that;  Yes, the probability is low enough that there is a need for further testing.

The point (0, 6) on the line perpendicular to the given line, passing through the given point that is also on the y-axis.

The given coordinates are (-6, -4) and (0, 6).

The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.

Now, put (x1, y1) = (-6, -4) and (x2, y2)=(0, 6) in slope formula m = (y2-y1)/(x2-x1)

So, m = (6+6)/(0+4)

= 12/4

= 3

The point on the line perpendicular to the given line,

Then the slope = -1/m

= -1/3

Substitute m=-1/3 and (x, y) = (0, 6) in y=mx+c, we get

6 = -1/3 (0) + c

⇒ c = 6

Now, substitute m=-1/3 and c = 6 in y=mx+c, we get

y = -1/3 x+ 6

Line is passing through y-axis, so y = -1/3 (0) +6

y=6

Therefore, the point (0, 6) on the line perpendicular to the given line, passing through the given point that is also on the y-axis.

Answer:

D. Replace f(x) with y

Step-by-step explanation:

apex

Yoshi needs to find the inverse of f(x) = 5x – 2. The first step is to Switch x and y. The correct answer is option C.

In mathematics, an inverse function is a function that "undoes" the actions of another function. If a function f(x) maps an input x to an output y, the inverse function, denoted as f^(-1)(x) or sometimes written as f(x)^(-1), maps the output y back to the original input x. The correct answer is option C.

To find the inverse of a function, the first step is to switch the x and y variables. In this case, the function is f(x) = 5x - 2.

To find the inverse, we need to switch x and y, so the new function becomes x = 5y - 2.

It's important to note that not all functions have an inverse. A function must be one-to-one (each input maps to a unique output) for an inverse to exist. Additionally, the domain and range of a function and its inverse are swapped.

Answer:

The proportion of people who can correctly match a dog to their owner (out of two options) is better than just guessing.

Step-by-step explanation:

In this case we need to test whether the proportion of people who can correctly match a dog to their owner (out of two options) is better than just guessing.

The hypothesis can be defined as follows:  

H₀: The proportion of people who can correctly match a dog to their owner is 50%, i.e. p = 0.50.  

Hₐ: The proportion of people who can correctly match a dog to their owner is more than 50%, i.e. p > 0.50.  

The information provided is:  

[tex]x=14\\n=16[/tex]

The sample proportion is:

[tex]\hat p=\frac {x}{n}=\frac{14}{16}=0.875[/tex]

Compute the test statistic value as follows:  

[tex]z=\frac{\hat p-p}{\sqrt{\frac{p(1-p)}{n}}}[/tex]

  [tex]=\frac{0.875-0.50}{\sqrt{\frac{0.50(1-0.50)}{16}}}\\\\=3[/tex]

The test statistic value is 3.  

The decision rule is:  

The null hypothesis will be rejected if the p-value of the test is less than the significance level.  

Compute the p-value as follows:

[tex]p-value=P(Z>3)\\\\=1-P(Z<3)\\\\=1-0.99865\\\\=0.00135\\\\\approx 0.0014[/tex]

The p-value is, p-value = 0.0014.

The p-value of the test is very small for all the commonly used significance level. The null hypothesis will be rejected.

Thus, there is not enough evidence to support the claim.

Conclusion:

The proportion of people who can correctly match a dog to their owner (out of two options) is better than just guessing.
