How do you do question #5?

Mathematics
1 answer:
andreev551 [17]4 years ago
3 0

Step-by-step explanation:

If two variables x and y are independent, then:

P(x and y) = P(x) P(y)

Or, in terms of conditional probability:

P(x given y) = P(x)

From part 3, 27.3% of the students are sophomores, 57.8% are juniors, and 14.8% are seniors.

From part 4, 31.6% of procrastinators are sophomores, 53.6% are juniors, and 14.8% are seniors.

Since the percent of procrastinators that are sophmores is not the same as the percent of students that are sophmores, the variables are not independent, which means there is a relationship between academic level and whether students procrastinate.

Answer:

Vertex: (3,0)

Max/min: min

axis of symmetry: x=3

Domain: (-∞,∞)

Range: [3,∞)

zeroes: (3,0)

Step-by-step explanation:

Vertex is where the graph changes directions (so in this case it's the point where it changes from decreasing to increasing) which I think is (3,0)

It's a minimum because the coefficent for the degree is positive

The axis of symmetry is just the x value of the vertex (which is x= 3)

the domain is all possible x values (-∞,∞)

The range is all possible y values [3,∞)

The zeroes is where the line hits the x axis, which is (3,0)

Prove that sin(n) diverges
Ivahew [28]
If you look at the graph of sin(n), you can notice that it oscillates every kpi/2 when k is odd. This oscillation proves that sin(n) diverges.

What is the area of the regular trapezoid below?<br> - 6 cm<br> T<br> 8 cm<br> 10 cm
Elenna [48]

Answer:

Area = 64 cm²

Step-by-step explanation:

To find the area, we have to follow some steps:

=> <u>Step 1: Make the bases similar:</u>

Since we have 2 bases given 6 and 10 we have to come up with a third base by finding their average:

(6 + 10) / 2

(16) / 2

8

So now that we know our base,

=><u> Our second step is to multiply the base we found by the height of the trapezoid:</u>

Area = common base * height

Area = 8 * 8

Area = 64 cm²

Hope this helps!

lilavasa [31]

Answer:

f(2) = 9

Step-by-step explanation:

It's give in the question,

Two different functions are,

f(x) = 4x + 1

g(x) = -2x

Then we have to find the output value of function 'f' for the input value x = 2.

By substituting the value of x in the function 'f',

f(2) = 4(2) + 1

     = 9

f(2) = 9

Find the value of x.
Mandarinka [93]

Answer:

⏩12°

Step-by-step explanation:

4x + 7° + 35° = 90° {being complementary angles }

4x + 42° = 90°

4x = 90° - 42°

4x = 48°

x = 48° / 4

x = 12°

Hope it will help :)❤
