The required probability for P(x<92) is 0.15866.

Given that,
Sample score = X =  92
Mean = μ = 98
Standard deviation = σ = 6
p(x ≤ 92 ) is to be determined

<h3>What is probability?</h3>

Probability can be defined as the ratio of favorable outcomes to the total number of events.

z = (X - μ) / σ
z = (92 - 98) / 6
z = - 1

Now
Probability,
p(x < 92) = P(z = -1)
p(x < 92)  = 0.15866   (from z score table)

Thus, The required probability for P(x<92) is 0.15866.

pochemuha

Answer: Divide Kayak budget by rental rate

Step-by-step Explanation:

As Joshua is renting for himself alone, the two available options would be the Single Kayak and the Single Sea Kayak.

He can determine the number of hours to rent a Kayak for by dividing his Kayak Budget by the rental rate per hour of the 2 options available to him.

<h2>Single Kayak</h2>

Budget available = $50

Rental rate = $15 per hour

Hours he can rent = 50/15

= 3.33 hours

<h2>Single Sea Kayak</h2>

Budget available = $50

Rental rate = $18 per hour

Hours he can rent = 50/18

= 2.78 hours

If (-2, y) lles on the graph of y = 3^x, then y =
sweet [91]
<h3>Answer:</h3>

\frac{1}{9}

<h3>Step-by-step explanation:</h3>

We know that x=-2, so substitute that into the equation. y=3^{-2}

With negative powers, instead of making the result negative, you divide one by it.  Mathematically speaking, x^{-y}=\frac{1}{x^y}.  This makes our equation: y=\frac{1}{3^2}

Finally, simplify the exponent. y=\frac{1}{9}

What is the slope - intercept equation for this line? ​
Makovka662 [10]

Answer:

y = -2x - 1

Step-by-step explanation:

the ? mark part or the first [] is the slope

the slope is rise / run

the "rise" is 2 down

the "run" is 1 left

so

-2 / 1 is the slope

the y intercept is -1 as the line touches the y axis at -1

so

y = -2x - 1

is your answer
