If

Answer:

1/36

Step-by-step explanation:

Answer:

1/36

Step-by-step explanation:

There is a 1/36 or a ~2.8% chance that a player will roll two sixes. Because the dice is cubed, the player will have a 1/6 probability of rolling a six one time. Because the player needs to get six 2 times in a row, you would simply need to multiply 1/6 by itself twice(1/6•1/6 or 1/6^2) which equals 1/36.

Answer: It is 8/10 Because 7+1 equals 8/10 so 7/10+1/10 equals 8/10.

Answer:

A number, such as 10 is a composite number because it is even.

Answer:

1/36

Step-by-step explanation:

A die can roll a 1,2,3,4,5,6

P (5) = number of 5's / total

        = 1/6

The 2nd roll is independent so the probability is the same

P (5) = number of 5's / total

        = 1/6

P(5, 5) = 1/6*1/6 = 1/36

Answer:

a) H0 : u = 28.5%

H1 : u < 28.5%

b) critical value = - 1.645

c) test statistic Z= - 1.41

d) Fail to reject H0

e) There is not enough evidence to support the professor's claim.

Step-by-step explanation:

Given:

P = 28.5% ≈ 0.285

X = 210

n = 800

[tex] p' = \frac{X}{n} = \frac{210}{800} = 0.2625 [/tex]

Level of significance = 0.05

a) The null and alternative hypotheses are:

H0 : u = 28.5%

H1 : u < 28.5%

b) Given a 0.05 significance level.

This is a left tailed test.

The critical value =

[tex] -Z_0.05 = -1.645 [/tex]

The critical value = -1.645

c) Calculating the test statistic, we have:

[tex]Z = \frac{p' - P}{\sqrt{\frac{P(1-P)}{n}}}[/tex]

[tex]Z = \frac{0.2625 - 0.285}{\sqrt{\frac{28.5(1-28.5)}{800}}}[/tex]

Z = -1.41

d) Decision:

We fail to reject null hypothesis H0, since Z = -1.41 is not in the rejection region, <1.645

e) There is not enough evidence to support the professor's claim that the proportion of obese male teenagers decreased.

Answer:

Step-by-step explanation:

8. Let's call the number x. We can set up the equation -3x - 5 = -10. Adding 5 to both sides, we have -3x = -5, and when we divide both sides by -3, we have x = 5/3.

9. Again, we'll call the number x. The equation is 2x - 3 = -13. We can write -3 instead of +(-3) because adding a negative number is the same as subtracting. Adding 3 to both sides, we have 2x = -10, and dividing bu -2, we have x = -5. Hope this helps!

g = number of goblins

w = number of wizards

There are 220 club members altogether, so

g + w = 220

There are 20% more goblins than wizards, so

g = 1.2 w

Substitute this into the first equation and solve for w, then for g.

1.2 w + w = 2.2 w = 220  ==>  w = 100

g = 1.2 w  ==>  g = 120

Answer:

Step-by-step explanation:

Since each tank is cylindrical, we would apply the formula for determining the total surface area of a cylinder which is expressed as

Total surface area = 2πr² + 2πrh

Where

r represents the height of the cylinder.

h represents the height of the cylinder.

π = 3.14

From the information given,

Height = 1.9

Diameter = 1.4

Radius = diameter/2 = 1.4/2 = 0.7

Total surface area = 2 × 3.14 × 0.7² + 2 × 3.14 × 0.7 × 1.9 = 3.0772 + 8.3524 = 11.4296 m²

Total surface area of the 3 cylinders = 11.4296 × 3 = 34.29 m²

Since a tin of paint covers 5 m², the number of tins paints that Tim will need to buy is

34.29/5 = 6.858

Since the tins of paint must be whole numbers, he needs to buy 7 tins of paints.

Answer:

Step-by-step explanation:

A general equation of a hyperbola is

 x^2     y^2

-------- - ------- = 1   (This applies only when the center of the hyperbola

 a^2     b^2                               is at (0, 0)  ).

You must compare the given equations to this standard form to identify which represents the hyperbola shown, and also you must share the illustration of the hyperbola.

The equation represents the hyperbola shown in the graph is  (y - 1)² / 9 - (x + 4)² / 4  = 1

A hyperbola is a type of smooth curve lying in a plane, defined by its geometric properties or by equations for which it is the solution set.

A hyperbola has two pieces, called connected components or branches, that are mirror images of each other and resemble two infinite bows.

Given that, a graph, showing hyperbola, we need to find the equation,

We have the general equation for up - down facing hyperbola as

(y - k)² / b²- (x - h)² / a²  = 1.

Let's start listing the properties of this graph -

Taking a look at the graph we see that the center point of our hyperbola here is (- 4, 1).

Therefore, (h, k) = (- 4,1).

This is the semi distance from the center to one of the vertices. Here it will be the distance from points (- 4,1) and (- 4,4) or 3 unit difference.

Therefore, a = 3.

That gives asymptotes. Now remember that it will be in the form

y = ± b / a.

We already know a = 3, so we have to find b.

Looking at this graph we can say that another point besides (- 4,1) that lies on the "dotted line" is (- 2, - 2).

Calculating the slope of the dotted line would be as follows,

Given: (- 4,1) and (- 2, - 2)

Slope = - 2 + 4 / - 2 - 1 = 2 / 3

We have the equation y = 2 / 3x.

Therefore, b = 2.

Let's substitute to equation...

h = - 4, k = 1, b = 2, a = 3

(y - 1)² / (3)²- (x + 4)² / (2)²  = 1

(y - 1)² / 9 - (x + 4)² / 4  = 1

Hence, the equation represents the hyperbola shown in the graph is  (y - 1)² / 9 - (x + 4)² / 4  = 1

Answer:

F

Step-by-step explanation:

x = 26-9

Answer:

F. 17

Step-by-step explanation:

There would only be one answer choice, and to find this, all you can do is subtract 9 from both sides, like so:

x + 9 = 26

   - 9    - 9

________

x = 17

This means that when you plug in 17 for x, the answer will come out to 26.

Answer:

  (1 3/4, 2 1/2)

Step-by-step explanation:

The point of intersection is an "ordered pair." That means the order of the two numbers is important. The first number means something different than the second number.

So, if you want a reasonable estimate for (1.8, 2.6), you need to have the first number in the estimate be close to 1.8. The offered choices are ...

  1 3/4 = 1.75

  2 1/2 = 2.5

  1 1/3 ≈ 1.33

The closest of these to 1.8 is 1.75, so the first choice is the best choice so far.

__

The second number of the estimate needs to be close to 2.6. The offered choices are ...

  2 1/2 = 2.5

  1 3/4 = 1.75

  1 1/3 = 1.33

The closest of these to 2.6 is 2.5, so the first choice is still the best choice.

  A reasonable estimate is (1 3/4, 2 1/2).

Answer:

Step-by-step explanation:

Hello!

Inez walked in the treadmill for 7/10hr and had stopped for 1/2hr. How much time he was actually working out?

Time in the treadmill is [tex]\frac{7}{10}[/tex] hr

1 hour is the whole, you can express it as [tex]\frac{10}{10}[/tex].

If you express it in minutes then [tex]\frac{10}{10} = 60min[/tex], then [tex]\frac{1}{10} = \frac{60}{10}= 6 min[/tex]

Now you can calculate the amount of time he was on the treadmill:

[tex]\frac{7}{10}= 7*6= 42 min[/tex]

Time he had stopped

[tex]\frac{1}{2}= 30min[/tex]

Between the time he was on the treadmill and the time he rested, he worked out for 42 + 30= 72 min = 1 hour and 12 minutes.

During a 12- hour period, the temperature dropped 48 °C how many degrees did the temperature dropped each hour?

You can use cross multiplication to calculate how many degrees per hour the temperature decreased:

If in 12 hrs it decreased 48ºC

Then in 1 hr it decreased [tex]\frac{1*48}{12} = \\[/tex] 4ºC

The elevation of Turpan Pendi in China is -185 meters. The elevation of the Qattara Depression in Egypt is -163 meters. Compare the two elevations using < or >.______________

To easily determine which elevation is higher than the other you have to order them from least to greatest in a number line. These measurements are negative, which means that, the "higher" the module is, the less in the number line the negative value will be:

----|---------------------------------------|--------------------------------|--

-185                                        -163                                 0

(The line is not on scale)

Using < or >, you can say that  -163 meters > -185 meters.
