(4 + 9 + 16 / 4) - 8 - (3 * 5)
(29 / 4) - 8 - (3 * 5) | Add up the numbers on left side.
(7.25) - 8 - (15) | Divide 29 by 4 and multiply 3 and 5.
-0.75 - (15) | Subtract 8 from 7.25

What is the sign of 3 x y 3xy3, x, y when x > 0 x>0x, is greater than, 0 and y < 0 y<0
Colt1911 [192]

Answer:

The sign is negative

Step-by-step explanation:

Given

Expression = 3xy

x > 0

y

Required

Determine the sign

The expression can be split into 3 factors

(3) (x) (y)

If x > 0 then x is positive and If y < 0 then y is negative

So, the expression becomes:

(+3) (+x) (-y)

<em />

Leave only signs

(+) (+) (-)

+ * + = -

So, we have:

(+*+) (-)

(+) (-)

+ * - = -

So, we have:

(+) (-) = -

<em>Hence, the sign of the expression is negative</em>

<em></em>

Take for instance;

x = 2

y = -4

The expression would be:

3 *2 * - 4 =-24 -- negative

a teacher plans a simulation to estimate the probability that a student will pick a vowel out of a bag of 26 tiles, each with a
Alex Ar [27]

Answer:

Yes

Step-by-step explanation:

Given that a teacher prepares 26 tiles with 5 vowels numbered 1 and 21 consonants numbered 2.

The probability for drawing vowel =\frac{5}{26}

Prob for consonant =\frac{21}{26}

If number of trials is atleast 30 we can expect reliable results.

Here the results are recorded for 120 times at random.

Since number of trials is large, we can expect a reliable and accurate results representing the actual probability.

This is because more the number of trials, the less would be the margin of error i.edeviationfrom the expected probability would be minimum
