There are 16 boys and 19 girls in a class. The teacher calls the
students' names randomly. What is the probability that the first
student called is a boy, the second student is also a boy and
the third student is a girl if the teacher calls the names with no
repetition? Enter your answer as a decimal rounded to the
nearest thousandth.

Answer:

this is a reflection across the x axis, not the y

Step-by-step explanation:

If it were flipped by the y axis, the d and the t would be on opposite sides of the quadrilateral, but theyre on tge same side, so its only flipped across the x axis. Hope this helps.

Answer:

4a. 13

4b. -4

Step-by-step explanation:

2x-6/5 = 4 (Muti each side by 5)

2x-6 = 20

2x = 26 (Divide each side by 2)

x = 13

7- 2x/4 = 9

-2x/4 = 2 (Muti each side by 4)

-2x = 8 (Divide each side by -2)

x = -4

Answer:

y = 1/2 x+4

Step-by-step explanation:

Slope intercept form is y = mx+b, where m equals the slope and b is the y-intercept.

The slope can be calculated using the formula [tex]m = \frac{y_{1}-y_{2} }{x_{1}-x_{2} }[/tex].

I'll be plugging in (2,5) and (4,6) to calculate the slope.

m = (6-5)/(4-2) = 1/2

The y-intercept is the y-coordinate of where the line meets the y-axis. In the graph, you can see that the line intersects with the y-axis at (0,4). The y-coordinate of (0,4) is 4, so therefore it is the y-intercept.

Plugin m = 1/2 and b = 4 into the slope-intercept formula (y = mx+b), and you get y = 1/2 x+4

Answer:

0.2

Step-by-step explanation:

6+4+3+2=total no of marble

=15

no of blue marble 3

[tex] \frac{3}{15} \\ = \frac{1}{5 } \\ = 0.2[/tex]

The probability that the marble is blue is 1/5 or 0.2.

Probability refers to potential. A random event's occurrence is the subject of this area of mathematics.

The range of the value is 0 to 1. Mathematics has incorporated probability to forecast the likelihood of various events.

The degree to which something is likely to happen is basically what probability means.

Given:

Red marbles= 6

Green marbles = 4

Blue marble = 3

Yellow marbles= 2

Total marbles= 15

So, the probability getting blue marble

= blue marble / total marble

= 3/15

= 1/5

Answer:

yes

Step-by-step explanation:

because although some of the other are missing to be a function, it has to have an element of x and of y, it does not matter that some do not have it with one of y and one of x is enough

And if you are talking about relation it is also because they comply with the rules

Answer:

Diameter:6.08

Radius=D/2=6.08/2=3.04

Step-by-step explanation:

Answer:

The radius is

[tex] \sqrt{29} [/tex]

The diameter is

[tex]2 \sqrt{29} [/tex]

Step-by-step explanation:

The area of the circle is represent as

[tex] a = \pi \times r {}^{2} [/tex]

Where r is the radius and a is the area. Since pi is a irrational number, we won't focus on doing nothing with that instead we just take the sqr root of both sides to find the r or radius.

[tex] \sqrt{29} [/tex]

Which is the radius and it cant be simplified so the radius is

[tex] \sqrt{29} [/tex]

The diameter is twice longer than the radius so we

[tex]2 \times \sqrt{29} [/tex]

Which is

[tex]2 \sqrt{29} [/tex]

Answer:

1/2

Step-by-step explanation:

The slope of the points (4,-3) and (3,-1) is -2

The slope of a line perpendicular to said points would be the opposite reciprocal which would be 1/2
