Solve the following :- 2n > 14. n > _ . 2. n/5≥ 11. n ≥ _. 3. –3y ≤ –18. y ≥ _____

1 answer:

3 0

The answers to the numbers are shown below.
1.) Divide both sides by two to yield an answer of n > 7.
2.) Cross multiply by multiplying the denominator, 5, by 11. This gives an answer of n ≥ 55.
3.) Divide both sides by -3. Since we have an operation involving a negative number, we invert the sign. Thus, the answer is y ≥ 6.

A ball is drawn randomly from a jar that contains 7 red balls, 5 white balls, and 4 yellow ball. Find the probability of the giv

Furkat [3]

Missing Part:

a. A red ball is drawn

b. A white ball is drawn

Answer:

a. $P(Red) = 0.4375$

b. $P(White) = 0.3125$

Step-by-step explanation:

Given

$Red = 7$

$White = 5$

$Yellow = 4$

First, we need to calculate the total

$Total = Red + White + Yellow$

$Total = 7+5+4$

$Total = 16$

Solving (a): Probability of Red.

This is calculated by dividing number of red balls by the total

So:

$P(Red) = \frac{Red}{Total}$

$P(Red) = \frac{7}{16}$

$P(Red) = 0.4375$

Solving (a): Probability of White.

This is calculated by dividing number of white balls by the total

So:

$P(White) = \frac{White}{Total}$

$P(White) = \frac{5}{16}$

$P(White) = 0.3125$

15. Use the unit circle to find the value of sin 3x/2 and cos 3x/2

My name is Ann [436]

Answer:

3xpi/2 is 270 degree counter-clockwise from Ox

That time P(x,y) is (0,-1)

=> x= 0 and y = -1 as you can see in picture.

=> Cos 3pi/2 = x = 0

=> Sin 3pi/2 = y = -1

Step-by-step explanation:

Not so slow.

This is a literal equation.

Aleksandr [31]

Assuming this is the equation you want to operate on:
$v^{2} = (v_0)^{2} + 2\cdot a \cdot \Deltax$
$2\cdot a \cdot \Delta x = v^{2} - (v_0)^{2}$
$a = \frac{v^{2} - (v_0)^{2}}{2\cdot \Delta x}$
Before final operation we have to assume that x is not equal to 0. :)
