which even definition corresponds to exactly one outcome of the experiment?

Answers

Answer: Option 'A' is correct.

Step-by-step explanation:

Since we have given that

There is six sides die :

So, the number of outcomes will be

1,2,3,4,5,6.

There is a card with numbers :

1,2,3,4,5,6,7,8,9,10.

We need to find the event corresponds to exactly one outcome of the experiment.

According to options:

A)Both numbers are 5s.

So, there is exactly one event regarding both numbers are 5's. i.e. (5,5).

B) Neither number is a 5.

There is more than one event having not a 5.

Like (1,1),(1,2) ..........

C) The sum of the numbers is 3.

It can be (1,2),(2,1).

so, there is having two events regarding the sum of the numbers is 3.

D) One of the numbers is a 3.

It can be (3,1), (3,2), (3,4)......

So, we can see that there is more than one event corresponds to one of the numbers is a 3.

Hence, Option 'A' is correct.

The chord of the circle is TR.

Given:

Given that the circle O has the points R, U, S, and T on it. Point O is traversed by segments SR and TU. The diagram also includes segment RT.

We must determine the circle's radii, diameter, and chord.

The circle's radii are as follows:

A circle's radius is the line that connects the circle's center to its perimeter.

The radius of the circle is represented by the letters OR, OT, OS, and OU in the diagram.

Circle circumference:

The diameter of a circle is the straight line that runs through its center and has its ends on the circle.

As a result of the diagram, the circle's diameters are TU and RS.

The circle's chord is:

A circle chord is a straight line with endpoints on the circle.

As a result of the diagram, the circle's chord is TR.

Consider the equation below.
–2(bx - 5) = 16
The value of xin terms of b is
The value of x when bis 3 is

Answers

Answer:

If b is 3, x=-1

Step-by-step explanation:

-2(3x-5)=16

use distributive property

-6x+10=16

take 10 away from both sides

-6x=6

divide both sides by -6

x=-1

The value of x in terms of b is given by equation x = -3/b

The value of x when b = 3 , is x = -1

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as A

Now , the value of A is

Substituting the values in the equation , we get

The given equation is:

-2(bx - 5) = 16

To solve for x in terms of b, we need to isolate x on one side of the equation. We can start by distributing the -2 on the left-hand side:

-2bx + 10 = 16

Next, we can subtract 10 from both sides:

-2bx = 6

Finally, we can divide both sides by -2b to solve for x:

x = -3/b

So the value of x in terms of b is -3/b.

To find the value of x when b is 3, we can substitute b = 3 into the equation we just found:

x = -3/b = -3/3 = -1

Hence , the equation is solved and when b is 3, the value of x is -1.

Answers

Answer:

18 degrees.

Step-by-step explanation:

115-97=18

The calculated measure of the angle MRN is 18 degrees

Calculating the measure of Angle MRN?

From the question, we have the following parameters that can be used in our computation:

Triangle = MNR

Angle N = 97 degrees

From the attached figure

Segment NM is an extension from the exterior angle of M

By the sum of opposite interior angles of triangle, we have

MRN + ∠N = 115 degrees

This means that

MRN + 97 = 115 degrees

Subtract 97 from both sides

MRN = 18 degrees

Hence, the measure of the angle MRN is 18 degrees

How do you set up this equation ?

Answers

Given:

Quadrilateral PQRS is a rhombus.

To find:

The value of y.

Solution:

In the rhombus PQRS,

PS = 10y and SR = y + 45

Property of rhombus:

All sides are congruent.

⇒ PS = SR

⇒ 10y = y + 45

Subtract y from both sides.

⇒ 10y - y = y + 45 - y

⇒ 9y = 45

Divide by 9 on both sides.

[tex]$\Rightarrow \frac{9y}{9} =\frac{45}{9}[/tex]

y = 5

Find the value of x. The diagram is not to scale. Explain your reasoning.

Answers

Answer:

x = 24

Step-by-step explanation:

Since SR = ST then Δ RST is isosceles, thus the base angles are congruent.

∠ SRT = ∠ STR = 4x - 60

∠ STR and ∠ STU are adjacent and supplementary, thus

∠ STR + ∠ STU = 180, substitute values

4x - 60 + 6x = 180, that is

10x - 60 = 180 ( add 60 to both sides )

10x = 240 ( divide both sides by 10 )

1. What If? If Alex had saved $333.34 a month for 3 months, how

much money would he have? If he had used his savings instead

of his credit card, how much less would his purchases have cost him?

2. How much less did Barry's loan, at an interest rate of 9%, cost than

Alex's loan at 21%?

Answers

Final answer:

Alex would have saved $1,000.02 over 3 months. The cost of purchases would have been less if he used his savings instead of a credit card because of no interest rates applied. Barry's loan is $120 less expensive than Alex's loan

Explanation:

If Alex had saved $333.34 a month for 3 months, he would have saved $333.34 x 3 = $1,000.02. As for the cost of purchases using savings instead of a credit card, we can't directly answer that without knowing the associated credit card interest rate & the time duration. In general, using a credit card would have cost more due to the interest applied to the unpaid balance.

For the second part of your question related to loans, let's assume both Alex and Barry took out loans of $1,000 each for one year. Alex's loan, with an interest rate of 21%, would cost him $1000 x 21/100 = $210 in interest. Barry's loan, at an interest rate of 9%, would cost him $1000 x 9/100 = $90 in interest. Therefore, Barry's loan costs $210 - $90 = $120 less than Alex's loan.

From the graph we see that there seems to be a linear relationship but not fully perfect.  Because so many points deviate from the line we can only say that there is a moderate association.

Whenever x increases y increases also the linear regression line of fit has a positive scope.

There are 8 marbles in a jar. One of the marbles is clear. What is the decimal expansion of 1/8? please help me

Answers

Answer:

Step-by-step explanation: 1/8 = .125

 move two decimals to right = 12.5

Final answer:

The decimal expansion of 1/8 is 0.125, which is also the probability of drawing a clear marble from a jar of eight marbles, if only one of those marbles is clear.

Explanation:

The question asks for the decimal expansion of 1/8. To determine the decimal expansion of the fraction, you simply divide the numerator (the top number, which in this case is 1) by the denominator (the bottom number, which in this case is 8). When performed, 1 divided by 8 results in the decimal 0.125. This concept is similar to calculating probabilities in which the total number of outcomes is divided by the desired outcome. For example, in the case of the marbles in a jar, if one is clear and there are eight total, the probability of drawing a clear marble is also 1/8 or 0.125.

Answers

Answer:

B, D, E

Step-by-step explanation:

I am assuming that the equation is y = [tex]\frac{1}{3}[/tex] * x and not y = [tex]\frac{1}{3x}[/tex].

Using y = (1/3)x, we can transpose the x, so that now we have y/x = 1/3.

Take note that the given options are in the format of (x, y). You can simply plug all the values, and whichever gave you a result of 1/3 is your answer.

B.) 2/6 = 1/3

D.) 5/15 = 1/3

E.) -1/-3 = 1/3

Final answer:

The ordered pairs that satisfy the equation y = 1/3x are B (6,2), D (15,5), and E (-3,-1). Ordered pairs are verified by substituting the x-value into the equation to see if the resulting y-value matches the pair.

Explanation:

To determine which ordered pairs satisfy the given linear equation y = 1/3x, we need to substitute the x-value of each ordered pair into the equation to see if the corresponding y-value is correct.

For pair A (4, 6), substitute x = 4 into the equation to see if y equals 6: 1/3 * 4  = 4/3 which does not equal 6, so A does not satisfy the equation.For pair B (6, 2), substitute x = 6: 1/3 * 6  = 6/3 which equals 2, so B does satisfy the equation.For pair C (3, 6), substitute x = 3: 1/3 * 3  = 3/3 which equals 1, not 6, so C does not satisfy the equation.For pair D (15, 5), substitute x = 15: 1/3 * 15  = 15/3 which equals 5, so D does satisfy the equation.For pair E (-3, -1), substitute x = -3: 1/3 * -3  = -3/3 which equals -1, so E does satisfy the equation.For pair F (1, 3), substitute x = 1: 1/3 * 1 = 1/3, which does not equal 3, so F does not satisfy the equation.

So the ordered pairs that satisfy the equation y = 1/3x are B (6,2), D (15,5), and E (-3,-1).
