Step-by-step explanation:

Given that:

Mean score (m) = 80

Standard deviation = 4

Acore within one standard deviation of the mean:

Zscore = ± 1

Using the relation:

Zscore = (x - mean) / standard deviation

Where x = score

±1 = (x - 80) / 4

4 = x - 80

±4 + 80 = x

x = - 4 + 80 = 76

x = 4 + 80 = 84

Scire with 1 standard deviation of the mean :

76 = 1 standard deviation below

84 = 1 standard deviation above

Answer:

it is still 0.80

Step-by-step explanation:

you don't need to round, just add a zero

Answer:

Kindly check explanation

Step-by-step explanation:

Given the following :

40 metres covered in 6 seconds

Max speed attained after 6seconds

75 meters covered after 11 seconds

Average Speed for first 40 meters :

Speed = distance / time

Speed = 40m / 6s

Speed = 6.67m/s

To obtain the maximum speed :

Next (75 - 40) meters = 35 meters was covered in (11 - 6)seconds = 5 seconds

Speed at this point is maximum :

Hence, maximum speed = (35m / 5s) = 7m/s

Suppose, Manuel runs for an additional z seconds after reaching max speed :

Distance from starting line 6+z seconds after race started?

Distance after 6 seconds = 40 metres

Distance after z seconds = 7 * z

Total distance = (40 + 7z)

What is Manuel's distance from the starting line x seconds after the race started (provided x≥6x)?

Distance for first 6 seconds = 40 meters + distance covered after 6 seconds = (7 * (x-6))

40 + 7(x - 6)

Answer:

60%

Step-by-step explanation:

12/20 or 6/10 or 3/5 simplified would be 60% of her students passed their test.

Answer:

The answer is 60%

Step-by-step explanation:

You have to convert the fraction 12/20. You divide this 12/20 which gives you 0.6. Then multiply 0.6 times 100.

Answer: d

Step-by-step explanation:

The domain of the function that is represented by the graph is: D. x ≥ -7.

The domain of a function are all the possible x-values in a function which are plotted against the y-values on the x-axis.

In the graph given, the x-axis where the line starts from is -7, and it extends to infinity to the right.

Therefore, the domain of the function is: D. x ≥ -7.

Answer:

B

Step-by-step explanation:

A graph is only a function when there is only one y value for each x value.

A trick is to draw a line through some points on the x-axis, and if the line goes through more than one point. Then it is not a function. (See picture)

Sorry, not all the lines are straight, but you get the point. B is the only one that doesn't have more than one point on the lines I drew.

Make a point where it can be at 7 and 4.

Basically, put a point 4 or 5 blocks right of the 7.

Next, put a point where it can be at 21 and 12.

Basically, put a point 11 or 12 block right of the 21.

Answer: You will plot (0,0) which is the beginning, then plot (4,7), then if you multiply 7 times 2 you get 14 flowers. With those 14 flowers you will put them on (8,14) 8 minutes 14 flowers, lastly you will put 12 minutes and 21 flowers down which will be (12,21). since there are 21 flowers and 12 minutes.

Step-by-step explanation:

Step-by-step explanation:

Given that,

A person walks 12.0 m east, then turns and goes 5.00 m west, then turns and goes back 2.00 m east.

(a) Distance is equal to total path covered during the entire journey.

Distance = 12 + 5 +2

Distance = 19 m

(b) The shortest path covered is equal to the shortest path traveled. Let east is positive and west is negative. So,

Displacement = 12 +(-5) +2

Displacement = 9 m

Answer:

Step-by-step explanation:

The distance between two points can be found by using the formula

[tex]d = \sqrt{ ({x1 - x2})^{2} + ({y1 - y2})^{2} } \\[/tex]

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

(-7, -2) and (11,3).

The distance between them is

[tex]d = \sqrt{( { - 7 - 11})^{2} + ({ - 2 - 3})^{2} } \\ = \sqrt{ ({ - 18})^{2} + ( { - 5})^{2} } \\ = \sqrt{324 + 25} \: \: \: \: \: \: \: \: \: \: \: \: \: \: \\ = \sqrt{349} \: \: \: \: \: \: \: \: \\ = 18.681541692... \: \: \: \: \: [/tex]

Step-by-step explanation:

Answer:

I think it will be 3....?

Answer:

mean 5

median 4

mode 3

Step-by-step explanation:

The mean is the average, or add up all the numbers and divide by the number of numbers

(3+5+2+4+3+4+3+5+16)/9

45/9 = 5

The median is the middle number when listed from smallest to largest

2,3,3,3,4,4,5,5,16

Since there are 9 numbers, the middle is the 5th number

2,3,3,3   ,4,     4,5,5,16

The median is 4

The mode is the number that appears most often which is 3 since it appears 3 times

Answer:

Step-by-step explanation:

Mean is an essential concept in mathematics and statistics. The mean is the average or the most common value in a collection of numbers.

How to calculate mean?

There are different ways of measuring the central tendency of a set of values. There are multiple ways to calculate the mean.

Arithmetic mean is the total of the sum of all values in a collection of numbers divided by the number of numbers in a collection. It is calculated in the following way:

Answer:

The value of y when x has a value of 9 is 18

Step-by-step explanation:

Functions

The variables x and y are said to have a quadratic relationship. That information is not enough to set up a general equation for both variables.

Furthermore, we know that tripling the value of x causes the value of y to be multiplied by 9. That leads us to establish a proportional equation between them, as follows:

[tex]y=kx^2[/tex]

Where k is an unknown constant.

Let's use the given point (3,2) to find the value of k:

[tex]2=k(3)^2[/tex]

[tex]2=9k[/tex]

Solving for k:

[tex]\displaystyle k=\frac{2}{9}[/tex]

The equation is now:

[tex]\displaystyle y=\frac{2}{9}x^2[/tex]

Now find y when x=9:

[tex]\displaystyle y=\frac{2}{9}(9)^2[/tex]

[tex]\displaystyle y=\frac{2}{9}\cdot 81=18[/tex]

The value of y when x has a value of 9 is 18
