What is the range of y = –5sin(x)? all real numbers Negative 5 less-than-or-equal-to y less-than-or-equal-to 5 all real numbers

Paraphin [41]

Answer:

The range of given function is

$[-5,5]$

Step-by-step explanation:

We are given the function:

$y = -5\sin(x)$

We have to find the range of the given function.

Range of function

Range is the collection of all possible values of y for the domain of function.

Range of basic sine function is

$-1\leq \sin(x) \leq 1$

Multiplying the range by -5

$5\geq -5\sin(x) \geq -5$

Thus, the range of given function is

$-5\leq -5\sin(x) \leq 5$

$-5\leq y\leq 5$

Thus, the range of given function is

$[-5,5]$

The attached image shows the graph for the given function.

Thirty students in the fifth grade class listed their hair and eye colors in the table below: Brown hair Blonde hair Total Green

Mars2501 [29]

Answer:

No, the events "brown hair" and "brown eyes" are not independent.

Step-by-step explanation:

The table that represents the hair and eye colors of thirty students of the fifth grade are given in table as:

Brown hair Blonde hair Total

Green eyes 9 6 15

Brown eyes 10 5 15

Total 19 11 30

No, the events "brown hair" and "brown eyes" are not independent.

Since, two events A and B are said to be independent if:

P(A∩B)=P(A)×P(B)

where P denotes the probability of an event.

Here we have:

A= students having brown hair.

B= students having brown eyes.

A∩B= students having both brown hair and brown eyes.

Now,

P(A)=19/30 (ratio of addition of first column to the total entries)

P(B)=15/30 ( ratio of addition of second row to the total entries)

Also,

P(A∩B)=10/30

Now as:

P(A∩B) ≠ P(A)×P(B)

Hence, the two events are not independent.
