Answer:

1006

Step-by-step explanation:

Take proportion, p = 62%

n = (Z² * pq) / M.E²

Margin error = 0.03

p = 62% = 0.62

q = 1 - p = 1 - 0.62 = 0.38

Zcritical at 95% = 1.96

n = (1.96² * (0.62*0.38)) / 0.03²

n = 0.90508096 / 0.0009

n = 1005.6455

n = 1006

Sample size = 1006

What is the width of the ornament at the volume of 2664.31 cm (use 3.14 for)
Aloiza [94]

Answer:

33.6

Step-by-step explanation:

this is a circle

so

the area of a circle = pi x radius squared(since it's a 2-D shape)

but this is 3-D

so

V = 2664.31 = (4/3)(\pir^{3})

you could also use

A = ³√(36 * π * V²) when A is the surface area

but those are too long, so let us just use the answer choices

V = 3.14 x answer choice x radius sqaured

V = 3.14 x 8.6 x radius sqaured

2664.31 = 3.14 x 8.6 x radius sqaured

radius sqaured =  2664.31/3.14 x 8.6

radius sqaured =  2664.31/27.004

radius sqaured can't be made with this

lets skip V

radius sqaured =  2664.31/3.14 x 17.2

radius sqaured = 2664.31/54.008

since 27.004 didn't work, and 54.008 is 2 times as that

radius sqaured = 2664.31/3,14 x 33.6

radius sqaured =  2664.31/105.504 ≈ 25

25 square rooted is 5

so

33.6

The probability that a plant is edible is 4/5 and the probability that a plant grows at a constant rate and is edible is 14/19.
miskamm [114]

Answer: Probability that a plant grows at a constant rate, given it is edible is given by \frac{35}{38}.

Step-by-step explanation:

Let B be an event that getting a plant grows at a constant rate.

Since we have given that

The probability that a plant is edible is given by

P(A)=\frac{4}{5}

The probability that a plant grows at a constant rate and is edible is given by

P(A\cap B)=\frac{14}{19}

We will use "Conditional probability ", i.e.

P(A\mid B)=\frac{P(A\cap B)}{P(A)}

P(A\mid B)=\frac{\frac{14}{19}}{\frac{4}{5}}\\\\P(A\mid B)=\frac{14\times 5}{19\times 4}\\\\P(A\mid B)=\frac{70}{76}\\\\P(A\mid B)=\frac{35}{38}

Hence, Probability that a plant grows at a constant rate, given it is edible is given by \frac{35}{38}.

Suppose f is a function. If 10 = f(-4), find the coordinates of a point on the graph of f?
Rashid [163]

Given:

For a function f, 10 = f(-4).

To find:

The coordinates of a point on the graph of f.

Solution:

We have,

10 = f(-4)

It means the value of function f is 10 at -4.

On a coordinate plane x-axis represents the input values and y-axis represents the output values of a function. So,

x-coordinate = input value = -4

y-coordinate = output value = 10

Therefore, the required coordinates of a point on the graph of f are (-4,10).

Enter the equation of the line in the form y=mx where m is the slope.Immersive Reader
kari74 [83]

Answer:

y = 1/2x

Step-by-step explanation:

The slope is the rise (up) over run (left or right depending on if the number is negative) between points. So the next point on the graph is up 5 and over 10. this simplified is 1/2. Then you put this into y=mx which is y=1/2x
