P( rolling a number greater than 2 and the coin landing on heads or tails)
irina [24]

The value of P(rolling a number greater than 2 and the coin landing on heads or tails) is 4/6

<h3>How to determine the probability?</h3>

The given parameters are:

Objects = Dice and Coin

The sample space of the objects are:

Dice = {1, 2, 3, 4, 5, 6}

Coin = {Head, Tail}

From the above sample spaces, we have:

P(Rolling a number greater than 2) = 4/6

P(Coin landing on heads or tails)  = 1

The required probability is then calculated as:

P(rolling a number greater than 2 and the coin landing on heads or tails) = P(Rolling a number greater than 2) * P(Coin landing on heads or tails)

Substitute the known values in the above equation

P(rolling a number greater than 2 and the coin landing on heads or tails) = 4/6 * 1

Evaluate the product

P(rolling a number greater than 2 and the coin landing on heads or tails) = 4/6

Hence, the value of P(rolling a number greater than 2 and the coin landing on heads or tails) is 4/6

There are 9.88 grams of sugar in 4 servings of grapes. How many grams of sugar are in a single serving of grapes?
Korolek [52]
Ok so grapes, 

We have 4 servings and 9.88 grams total, so to find one serving we just need to divide by 4. 

9.88/4 = 2.47 per serving

What is the range of the function defined as y=5
seraphim [82]
\bf \begin{array}{cllll}&#10;x&y\\&#10;\textendash\textendash\textendash\textendash\textendash\textendash&\textendash\textendash\textendash\textendash\textendash\textendash\\&#10;-7&5^{-7}\to \frac{1}{5^7}\to \frac{1}{78125}\\\\&#10;-3&5^{-3}\to \frac{1}{5^3}\to \frac{1}{125}\\\\&#10;0&5^0\to 1\\\\&#10;3&5^3\to 125\\\\&#10;7&5^7\to 78125&#10;\end{array}

so... you can keep on going towards the negatives with "x", or towards the positives with "x", notice, if the "x" is negative, "y" is just a fraction, positive, but a fraction

and if "x" is positive, "y" is a positive integer
even when x =0, "y" never became 0, and is never negative either

so, the range is, "y" is always positive, but not 0, or  y>0

Given sinθ = 2/5 and cosθ &lt; 0:<br> 1. Find cscθ<br> 2. Find cotθ
Tems11 [23]

Recall that

sin²(<em>θ</em>) + cos²(<em>θ</em>) = 1

for all <em>θ</em>, and given that cos(<em>θ</em>) < 0, we find that

cos(<em>θ</em>) = -√(1 - sin²(<em>θ</em>)) = -√(1 - (2/5)²) = -√(21)/5

Now,

csc(<em>θ</em>) = 1/sin(<em>θ</em>) = 1/(2/5) = 5/2

and

cot(<em>θ</em>) = cos(<em>θ</em>)/sin(<em>θ</em>) = (-√(21)/5)/(2/5) = -√(21)/2
