P(2 reds) = 1/45

Step-by-step explanation:

P(2 reds) = P(1st red) * P (2nd red) = 2/10 * 1/9 = 1/45

The side b is approximately 80.02 feet in length. In a right triangle ABC with angle C equal to 90°, if angle B is 37.56° and side a is 49.94 feet, we can solve for side b using the trigonometric function sine.

First, we can label the triangle as follows:

Side a is opposite angle A,

Side b is opposite angle B,

Side c is the hypotenuse.

Let's label the triangle with the given and asked for information. Angle C is the right angle, angle B is 37.56°, side a is 49.94 feet, and side b is the side we are trying to find.

Using the sine function, we have:

sin(B) = opposite/hypotenuse

sin(37.56°) = a/b

Now we can substitute the known values:

sin(37.56°) = 49.94/b

To solve for b, we rearrange the equation:

b = 49.94 / sin(37.56°)

Using a calculator, we find:

b ≈ 80.02 feet.

The true statement exists

2. <1 + <3 = 180 because form a straight angle.

3.  ∠3 ≅ ∠6 because they are alternate interior angles.

4. ∠1 and ∠6 are supplementary because ∠3 ≅ ∠6 and m∠1 + m∠3 = 180°.

If two lines in a plane can be stretched indefinitely in both directions without coming to an intersection, they are said to be parallel.

If the equivalent angles generated when two lines are intersected by a transversal line are equal, the lines are parallel. Typically, the comparable angles are situated side by side and on the same transversal side.

If the alternate internal angles so created are equivalent, two lines sliced by a transversal line are considered parallel. The pairs of the alternate interior are often located on the inner side but are located on the opposing sides of the transversal.

1. <3 = <2 because of vertically opposite angle.

Therefore, it is false

2. <1 + <3 = 180 because form a straight angle.

Therefore, it exists true.

3.  ∠3 ≅ ∠6 because they are alternate interior angles.

Therefore, it exists true.

4. ∠1 and ∠6 are supplementary because ∠3 ≅ ∠6 and m∠1 + m∠3 = 180°.

Therefore, it exists true.

Answer:

a, b and c.

Step-by-step explanation:

The statistical inference may be defined as the process of using the data analysis to infer the properties of an underlying distribution for a probability.

In the context, for testing the population proportion p, the following conditions are used to verify the inference procedures so as to make the statistical inferences :

-- data that are collected by a random assignment or by a random sample.

-- sample size should be less than 10% of population size.

-- The \($n \ p_0 \geq 10$\) and the \($n(1-p_0) \geq 10$\) for the sample size \($n$\) as well as for the  hypothesis proportion, \($p_0.$\)

The significance level is set at 5% and the probability of the result is 3.6% which is less than the significance level. The result is statistically significant

Probability simply means the chance that a particular thing or event will happen. It is the occurence of likely events. It is simply the area of mathematics that deals with the numerical estimates of the chance that an event will occur or that a particular statement is true

The probability of the treatment group’s mean being greater than the control group’s mean by 8 points or more will be:

= (26 + 8 + 2)/1000

= 36/1000

Answer:

Jordan worked 18 hours lifeguarding and 15 hours walking dogs.

Step-by-step explanation:

To solve this problem, we can set up a system of two equations to represent the given information. Let "L" represent the number of hours Jordan worked lifeguarding and "W" represent the number of hours he worked walking dogs.

The first equation will represent the total amount of money Jordan earned:

13L + 10W = 177

The second equation will represent the difference in hours between the two jobs:

L - W = 3

We can solve this system of equations using either substitution or elimination.

Using substitution, we can solve for one variable in terms of the other and substitute that expression into the other equation to solve for the other variable.

Solving the second equation for L, we get:

L = W + 3

Substituting this expression for L into the first equation, we get:

(W + 3) + 10W = 177

Combining like terms, we get:

11W + 3 = 177

Subtracting 3 from both sides, we get:

11W = 174

Dividing both sides by 11, we get:

W = 15.818181818181818

Since the number of hours worked must be a whole number, we can round down to 15 hours. Substituting this value back into the equation L = W + 3, we get:

L = 15 + 3 = 18

Therefore, Jordan worked 18 hours lifeguarding and 15 hours walking dogs.

Answer:

16

Step-by-step explanation:

becasue from -21 to -5 it's 16 units (-21 - -5= 16).

The translation of the parent function f (x) = | x | depends upon whether x value has been changed of whether the y value has been changed.

We are given the parent function as:

f (x) = | x |

Now, we need to match the functions with their correct translations.

For the function f (x) = | x | - 4:

This can also be written as:

f (x) + 4 = | x |

So, the translation will be vertical translation up 4 units.

For the function f (x) = | x + 4 | :

The translation for this will be horizontal translation right 4 units as x will increase by 4 units.

For the function f (x) = | x | + 4:

This can also be written as:

f (x) - 4 = | x |

So, the translation will be vertical translation down 4 units.

For the function f (x) = | x - 4 | :

The translation for this will be The translation for this will be horizontal translation right 4 units as x will increase by 4 units as x will decrease by 4 units.

Therefore, we get that, the translation of the parent function depends upon whether x value has been changed of whether the y value has been changed.

Step-by-step explanation:

Given

Dogs : Cats = 2 : 3

Required

Determine the possible number of dogs and cats at the store

The question requires options; since there are none, I'll answer on a general terms.

We have the dog to cat ratio to be:

Dogs : Cats = 2 : 3

Multiply ratio by any number (say 7)

Dogs : Cats = 2 * 7 : 3 * 7

Dogs : Cats = 14 : 21

This means that if there are 14 dogs, then there are 21 cats.

Multiply the ratio by another number (say 4)

Dogs : Cats = 2 * 4 : 3 * 4

Dogs : Cats = 8 : 12

This implies:

8 dogs and 12 cats

In conclusion, the number of dogs, when divided by the number of cats must equal ⅔.

The graph of the equation y = (s + 2)(s - 3) is plotted and it cuts the x - axis at the points -2 and 3.

Parabola is a plane curve generated by a point moving so that its distance from a fixed point is equal to its distance from a fixed line.

Given is a function as -

y = (s + 2)(s - 3)

We have -

(s + 2)(s - 3)

s(s - 3) + 2(s - 3)

s² - 3s + 2s - 6

s² - s - 6

Replace 's' with 'x'. Now, you will get a quadratic equation as follows -

x² - x - 6

The graph of a quadratic equation represents a parabola. The parabola will cut the x - axis at the points -

(x - 2)(x - 3) = 0

x = -2 and x = 3

Therefore, the graph of the equation y = (s + 2)(s - 3) is plotted and it cuts the x - axis at the points -2 and 3.
