Answer:

The correct option is  A

Step-by-step explanation:

From the question we are told that

   The  mean is  \mu  =  0.8 \ pounds

    The standard deviation is  \sigma =  0.25  \  pounds

Generally the the probability that a  randomly selected zucchini will weigh between 0 55 pound and 13 pounds is mathematically represented as

       P(0.55 <  X  <  1.3)  =  P(\frac{0.55 - 0.8}{ 0.25} <  \frac{X -  \mu}{\sigma }  <  \frac{1.3 - 0.8}{0.25})

=>    P(0.55 <  X  <  1.3)  =  P( -1 <  Z  <  2 )

So looking the option of normal curves given in the question we see that it is option A that matches our interval

Ierofanga [76]

Answer:

\cot(x)  =  - 1 \: and \:  \cos(x)  =  -  \frac{ \sqrt{2} }{2}

Step-by-step explanation:

The given point is :

( -  \frac{ \sqrt{2} }{2}, \frac{ \sqrt{2} }{2})

This point is in the second quadrant.

This means:

\cos(x) = -  \frac{ \sqrt{2} }{2},  \sin(x) =  \frac{ \sqrt{2} }{2})

Cotangent is cosine/sine

\cot(x)=\frac{ \frac{ \sqrt{2} }{2} }{ -  \frac{ \sqrt{2} }{2} }  =  - 1

The grade point average (GPA) of the students at Lakeview High School is normally distributed with a mean of 3.1 and a standard
Morgarella [4.7K]
Approximately 1718 have a score within that range.

We calculate the z-score for each end of this spectrum:

z = (X-μ)/σ = (2.5-3.1)/0.3 = -0.6/0.3 = -2

Using a z-table (http://www.z-table.com) we see that the area to the left of, less than, this z-score is 0.0228.

For the upper end:
z = (3.7-3.1)/0.3 = 0.6/0.3 = 2

Using a z-table, we see that the area to the left of, less than, this z-score is 0.9772.

The probability between these is given by subtracting these:
0.9772 - 0.0228 = 0.9544.

This means the proportion of people that should fall between these is 0.9544:
0.9544*1800 = 1717.92 ≈ 1718

natita [175]

Answer: 1 / 27

Step-by-step explanation: p (B1) = 1 / 3

p (B2) = 1 / 3

p (B3) = 1 / 3

pro (B1 X B2 X B3) = 1 / 3 X 1 / 3 X 1 / 3 = 1 / 27

A pebble is tossed into the air from the top of a cliff. The height, in feet, of the pebble over time is modeled by the equation
Charra [1.4K]

Answer:

96

Step-by-step explanation:

The maximum height reached by the pebble modeled by the quadratic function,

h(t)=-16t^2+32t+80, can be found by finding the vertex.

Let's first find the t-coordinate of the vertex . The max height will correspond to this value of t which means we have to find the h(t)-coordinate.

When comparing h to at^2+bt+c, we see that:

a=-16

b=32

c=80

We need to evaluate the following to find the t-coordinate of the vertex:

t=\frac{-b}{2a}

t=\frac{-32}{2(-16)}

t=\frac{-32}{-32}

t=1

So now to find the correspond h(t)-coordinate, we will need to replace t in -16t^2+32t+80 with 1:

-16(1)^2+32(1)+80

-16(1)+32+80

-16+32+80

16+80
