The answer is 1.25%
Because $40 is 100% then 40 cents is 1%
50 cents is 1% and 1/4 of a percent
Add 1 and 1/4 to get 1.25

Answer:

1%

Step-by-step explanation:

We need our two numbers to have the same units. Since one number is in cents and the other is in dollars, we should change one of them. It could be either one.

Both numbers in cents:

50/4000

OR, both numbers in dollars:

.50/40.00

Either of these will work. Divide, you will get a decimal answer. Then multiply by 100 to change to a percent.

50÷4000 (OR .5/40)

= 0.0125

times by 100

0.0125 × 100

= 1.25% but the directions said to round to the nearest whole number, that's 1%

A random variable x x has a Normal distribution with an unknown mean and a standard deviation of 12. Suppose that we take a rand
Paul [167]

Answer:

95% Confidence Interval: (94.08,101.92)    

Step-by-step explanation:

We are given the following in the question:

Sample mean, \bar{x} = 98

Sample size, n = 36

Alpha, α = 0.05

Population standard deviation, σ = 12

95% Confidence Interval:

Formula:

\mu \pm z_{critical}\frac{\sigma}{\sqrt{n}}

Putting the values, we get,

z_{critical}\text{ at}~\alpha_{0.05} = 1.96

98 \pm 1.96(\dfrac{12}{\sqrt{36}} ) = 98 \pm 3.92 = (94.08,101.92)

[x] [y]
julsineya [31]

Answer:

B) x = 1, y = 46/3

Step-by-step explanation:

The general equation for a straight line is

y = mx + b

Step 1. Find the <em>slope of the line </em>

The slope m is

m =(y₂ -y₁)/(x₂/x₁)

Two of your points are (0, 2) and (3, 7).

m = (7 – 2)/(3 – 0)

m  = 5/3

Step 2. Find the <em>equation of the line</em>

Use point (0, 2).

2 = ⁵/₃ × 0 + b

2 = 0 + b

b = 2

The equation of the line is

y = ⁵/₃x + 2

===============

Step 3.Find the coordinates of the <em>first missing point</em>.

(x, 11/3)

11/3 = ⁵/₃x + 2     Multiply each side by 3

  11 = 5x + 6       Subtract 6 from each side

  5 = 5x              Divide each side by 5

  x = 1

The missing value is x = 1.

===============

Step 4. Find the coordinates of the <em>second missing point </em>

(8, y)

  y = ⁵/₃ × 8 + 2   Multiply each side by 3

3y  = 40 + 6        Combine like terms

3y = 46               Divide each side by 3

y = 46/3

The missing value is y = 46/3.

Your three known points give the green line in the graph below.

The orange dot represents the first missing point at (1, 11/3).

The red dot represents the second missing point at (8, 46/3).

The table below shows the surface area y, in square inches, of a shrinking puddle in x hours: Time (x) (hours) 1 4 7 10 Surface
zhannawk [14.2K]
The picture of how the graph looks like is shown in the picture.

Part A. The correlation coefficient, R², is the quantitative evaluation of how the data points are well-fitted to a model. The closer it is to 1, the better. But a R²=1 is very ideal and rare. This can be only true if the points coincides exactly with the given model. Since we can see in the graph that the points are exaclty passed through by the linear model, the correlation coefficient is 1.

Part B. The slope of the graph is measured between two points as Δy/Δx. So, between 1 to 4 hours, the slope is: (85-100)/(4-1) = -5. The slope represents the instantaneous rate of change of surface area with time. It is called instantaneous because the change was only between than interval, not the whole set of data. Also, the negative sign signifies that the trend is decreasing.

Part C. The data represents causation if the time was the cause of the change of the pond's surface area. However, this is not technically true because there might be other factors to be considered like environmental conditions. But, definitely, these data are in correlation because together they show an observable trend.
