Answer:

y + 1/2 = 4(x - 2)

Step-by-step explanation:

Use the point-slope equation y - k = m(x - h).

Gabby is buying flowers for a friend. She can choose daisies, carnations, or sunflowers. She can put the flowers in a clear, red

Combination tells the number of ways an object can be arranged. The number of all of the possible combinations Gabby can have is 9.

<h3>What is Combination?</h3>

The combination helps us to know the number of ways an object can be arranged without a particular manner. A combination is denoted by 'C'.

$^nC_r = \dfrac{n!}{r!(n-r)!}$

where,

n is the number of choices available,

r is the choices to be made.

We know that the number of options of the flower with Gabby is 3( daisies, carnations, or sunflowers) and the color choices she has is (clear, red, or blue), therefore, she $^3C_1$ choices for the flower, also, she has $^3C_1$ choices for color.

$\text{Total number of choices with Gabby} = \text{Choices of flower} \times \text{Choices of color}$

$= ^3C_1 \times ^3C_1 \\\\= 9$

Hence, the number of all of the possible combinations Gabby can have is 9.

Answer:

$\frac{27}{1024}$

Step-by-step explanation:

So the chance of getting yellow is 0.25

Getting it once is 0.25

Getting it twice is 0.25 • 0.25

Not getting it is 0.75

So we have 0.25 • 0.25 • 0.75 • 0.75 • 0.75 = $\frac{27}{1024}$

Please help, I'm stuck on this question

vesna_86 [32]

Answer: Option C

$a> 0$

Step-by-step explanation:

The graph shows a radical function of the form $f(x)=a(x+k)^{\frac{1}{n}}+c$

Where n is a positive number.

For this type of function, if the coefficient $a> 0$ then then when x tends to $\infty$ f(x) tends to $\infty$ and when x tends to $-\infty$ then f(x) tends to $-\infty$ .

Notice in the graph that as x increases then f(x) also increases and as x decreases f(x) also decreases.

This indicates that the coefficient $a> 0$

There are 125 students in sixth grade. 2/3 of the sixth graders ride the bus. How many sixth graders ride the bus?

Luden [163]

125 ÷ 3 = 41.6666666667

41.66666666667 X 2
= 83.3333......
Technically not correct, because you cannot split sixth graders into pieces, so you would probably round it to 84 students.
