Question 13
Which of the following is an equivalent equation obtained by completing the square of the expression below?

x^2 + 6x - 8 = 0

Answers

Answer:

B) (x + 3)^2 = 17

Step-by-step explanation:

To complete the square you need to put x + or - half of the x coefficient.

So here it would be (x + 3)^2. However, we're trying to find x^2 + 6x - 8 = 0, not x^2 + 6x + 9 =  0, which is what (x + 3)^2 expands to. So we need to -9 from x^2 + 6x + 9 = 0 and add -8 from the original equation.

This simplifies to (x + 3)^2 - 9 - 8 = 0    --> (x + 3)^2 - 17 = 0

Then all you need to do is rearrange to give: (x + 3)^2 = 17

B) Read single-digit numbers until finding the first 0 or 1. Count the number of 0s and 1s.

C) Read single-digit numbers until finding the first 0 or 1. Count the number of digits needed to get the first 0 or 1.

D) Read 100 single-digit numbers. Count the number of digits needed to get a 0 and the number of digits needed to get a 1

Answers

Considering the probability concept, a random number table could be used as follows:

C) Read single-digit numbers until finding the first 0 or 1. Count the number of digits needed to get the first 0 or 1.

What is a probability?

A probability is given by the number of desired outcomes divided by the number of total outcomes.

In this problem, we want to count the number of spins it takes to reach values of 0 or 1, when there are 10 possible outcomes, hence option C is correct.

To find the y-intercept substitute x as 0

[tex]y = 1 \times {0}^{2} + 7 \times 0 - 5[/tex]

[tex]y = 1 \times 0 + 0 - 5[/tex]

[tex]y = 0 + 0 - 5[/tex]

[tex]y = - 5[/tex]

Thus, The y-intercept is -5...~
Explanation:

We know that:

The y-intercept of an equation is the constant. Constants are the numerals in the equation.

Finding the y-intercept.

In the equation provided, we can see only one constant.

=> y = 1x² + 7x - 5

Thus, the y-intercept is -5.

One of the events occurs, or both occur.

B.
Neither event occurs.

C.
One of the events occurs but not both.

D.
Both of the events occur.

Answers

Answer:

a is the answer

Step-by-step explanation:

The equation of P(E1 ∪ E2) that represents the condition that the mutually exclusive events is one of the events occurs, or both occur which is correct option(A).

What are Mutually Exclusive events?

Mutually Exclusive events is defined as in probability the particular addition rule is applicable when two occurrences are incompatible with one another. It claims that the probability of either event is equal to the probability of each event separately.

If E₁ and E₂ are said to be mutually exclusive events then the probability of an event E₁ occurring or the probability of event E₂ occurring is given as P(E₁) + P(E₂) :

P(E₁ ∪ E₂) = P(E₁) + P(E₂)

Hence, the equation of P(E1 ∪ E2) that represents the condition that the mutually exclusive events is one of the events occurs, or both occur.

Given the figure below, find the values of x and z.

Answers

Answer:  z = 107; x = 5

Step-by-step explanation:

z = 107   They are vertically opposite angles, which they are equal.

z + (6x + 43) = 180

1. Plug in 107 for z.

107 + (6x + 43) = 180

2. Get rid of parentheses.

107 + 6x + 43 = 180

3. Sum up the number in the left sides.

      6x + 150 = 180

4. Subtract 150 from both sides.

                6x = 30

5. Divided 6 from both sides.

                  x = 5

The speed of an object can be found by dividing the distance traveled by the time it took. It takes Jamal $36$ seconds to skate once around a $500\text{ }\text{m}$ rink. If it takes Tory $40$ seconds to skate the same distance, what is the difference in their speeds?

Answers

Answer:

Difference = 13.9 m/s

Step-by-step explanation:

Speed of an object = distance traveled/time taken

Jamal takes 36 seconds to skate 500 m rink. Let his speed is v. So,

[tex]v=\dfrac{500\ m}{36\ s}\\\\=13.89\ m/s[/tex]

Tory takes 40 seconds to skate 500 m rink. Let his speed is v'. So,

[tex]v'=\dfrac{500\ m}{40\ s}\\\\=12.5\ m/s[/tex]

The difference in their speeds,

D = 13.89 - 12.5

= 1.39 m/s

Hence, the difference in their speeds is 13.9 m/s.
