_____=amount received after redemption -amount invested

Answer:

1) the probability that the proportion of vegetarians in the sample would be greater than 9% is 0.1902

2) the probability that the mean of the sample would differ from the population mean by less than 1.1 points in the is 0.3616

p( /x" - u/ < 0.47 ) = 0.3616

Step-by-step explanation:

1)

Given that;

p = 8% = 0.08 and n = 569

what is the probability that the proportion of vegetarians in a sample of 569 Americans would be greater than 9% (0.09)

that is;

p( p" > 0.09) = ?

p( p" > 0.09) = p( z > [(0.09 - 0.08)/(√((0.08(1 - 0.08))/569))] )

= p( z > (0.01 / 0.0114))

= p ( z > 0.8772)

= 0.1902

Therefore the probability that the proportion of vegetarians in the sample would be greater than 9% is 0.1902

2)

Given that;

mean points obtained in an aptitude examination u = 166

standard deviation α = 19

sample size n = 66

x" - u = 1.1

first we say

x-score = (x" - u) / (α/√n) = 1.1 / (19/√66) = 1.1 / 2.3387 = 0.47

p( -0.47 < z < 0.47 )

= p( z < 0.47) - p( z < - 0.47)

= 0.6808 - 0.3192

= 0.3616

Therefore the probability that the mean of the sample would differ from the population mean by less than 1.1 points in the is 0.3616

p( /x" - u/ < 0.47 ) = 0.3616

How do I figure out the sales tax?

Calculating Total Cost. Multiply the cost of an item or service by the sales tax in order to find out the total cost. The equation looks like this: Item or service cost x sales tax (in decimal form) = total sales tax. Add the total sales tax to the Item or service cost to get your total cost.

Step-by-step explanation:

Step 1: Define

Find points from chart.

Point (-7, -7)

Point (-4, 14)

Step 2: Find slope m

Answer:

[tex]\boxed {\boxed {\sf m=7}}[/tex]

Step-by-step explanation:

To find the slope, we can use the slope formula.

[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]

where (x₁, y₁) and (x₂, y₂) are points on the line.

We can pick any two points in the chart.

Let's use (-1, 35) and  (2,56).

If we use these points, then the variables are:

[tex]x_1=-1 \\y_1=35 \\x_2=2 \\y_2=56[/tex]

Substitute the values into the formula.

[tex]m=\frac{56-35}{2--1}[/tex]

Solve the numerator.

[tex]m=\frac{21}{2--1}[/tex]

Solve the denominator.

[tex]m=\frac{21}{3}[/tex]

Divide.

[tex]m=7[/tex]

The slope of the line is 7

Answer:

g(f(x)) = 5x^2 - 15x + 36

Step-by-step explanation:

f(x) = x² – 3x + 9

g(x) = 5x – 9

(g o f)(x)

g(f(x))

x = f(x) = x^2 - 3x + 9

g(x^2 - 3x + 9)

= 5(x^2 - 3x + 9) - 9

g(f(x)) = 5x^2 - 15x + 36

Answer:

[tex]4.5\ \text{s}[/tex]

Step-by-step explanation:

t = Time taken

u = Initial velocity =17 m/s

v = Final velocity

s = Displacement

a = Acceleration

g = Acceleration due to gravity = 9.81 m/s² = a

[tex]v^2-u^2=2as\\\Rightarrow s=\dfrac{v^2-u^2}{2a}\\\Rightarrow s=\dfrac{0^2-17^2}{2\times -9.81}\\\Rightarrow s=14.73\ \text{m}[/tex]

Total height the rock is to fall when it is 8 meters from the ground is [tex]14.73+(31-8)=37.73\ \text{m}[/tex]

[tex]v=u+at\\\Rightarrow t=\dfrac{v-u}{a}\\\Rightarrow t=\dfrac{0-17}{-9.81}\\\Rightarrow t=1.73\ \text{s}[/tex]

Time taken to reach the maximum height is 1.73 s.

[tex]s=ut+\dfrac{1}{2}at^2\\\Rightarrow 37.73=0+\dfrac{1}{2}\times 9.81t^2\\\Rightarrow t=\sqrt{\dfrac{37.76\times 2}{9.81}}\\\Rightarrow t=2.77\ \text{s}[/tex]

Time taken from the maximum height to the point which is 8 m from the ground is 2.77 s.

So, time taken from the moment of the throw to the point 8 m from the ground is [tex]1.73+2.77=4.5\ \text{s}[/tex].

Answer:

Rate of Change / Slope = 1.75 (or 7/4)

Step-by-step explanation:

Slope is Rise/Run which is (y2-y1)/(x2-x1). When we plug in both ordered pairs, we get (19.25-14)/(11-8)=5.25/3=1.75 as the slope.

The rate of change is the ratio of the rise and the run of the line. Hence, the rate of change of the line is 1.75

Rise = y2 - y1 = (19.25 - 14) = 5.25

Run = x2 - x1 = (11 - 8) = 3

Rate of change = (5.25 / 3) = 1.75

Therefore, the rate of change for the line is 1.75

Answer:

39

Step-by-step explanation:

Since a square has 4 equal sides, it's safe to do [tex]\frac{52}{4}[/tex] to get each side length (each side is 13 mm).

Dilating a side means you're multiplying it by the scale factor. This means that you're doing [tex]13*3[/tex] to each side (each side is 39 mm).

Work Shown:

P(A or B) = P(A) + P(B) - P(A and B)

P(A or B) = 0.8 + 0.55 - 0.35

P(A or B) = 1.35 - 0.35

P(A or B) = 1

A probability of 1 means there is 100% certainty the event happens. This must mean that there are only possible outcomes are: either event A happens, or B happens, or possibly both A and B happen simultaneously.

Answer:

[tex]Ratio = 0.74[/tex]

Step-by-step explanation:

Represent

- Andy with A

- Christopher with C

[tex]A = 3.5L[/tex]

[tex]C = 2580mL[/tex]

Required

Determine the ratio of C to A

Ratio is represented as thus:

[tex]Ratio = C:A[/tex]

Rewrite as fraction

[tex]Ratio = \frac{C}{A}[/tex]

This gives

[tex]Ratio = \frac{2580mL}{3.5L}[/tex]

Convert L to mL

[tex]Ratio = \frac{2580mL}{3.5*1000mL}[/tex]

[tex]Ratio = \frac{2580mL}{3500mL}[/tex]

[tex]Ratio = \frac{2580}{3500}[/tex]
