180 is the degrees a straight line segment is. This means that
4x + 3x + 2x = 180.
Since these all have the same variable (x), then you can add the coefficients. (4,3,2)
9x = 180
180/9 = x

X = 20

Answer:

The value of x is 20°

Step-by-step explanation:

Here, For a given Straight Line

We know that, The Straight angle is an angle equal to 180°

So,

4x + 3x + 2x = 180°

9x = 180°

Divide by 9 from both side

9x/9 = 180°/9

x = 20°

Thus, The value of x is 20°

<h3>FOR VERIFICATION ONLY:</h3>

4x + 3x + 2x = 180°

9x = 180°

95(20°) = 180°

180° = 180°

Hence, L.H.S = R.H.S

Alan recorded the points he scored on the basketball court in ms2 school yard. What is the mean absolute deviation of his scores

Alecsey [184]

Answer:

The mean absolute deviation is: 7.44

Step-by-step explanation:

Given

$Scores: 98, 78, 84, 75, 91$

Required

The mean absolute deviation

First, calculate the mean

$\bar x = \frac{\sum x}{n}$

$\bar x = \frac{98+78+84+75+91}{5}$

$\bar x = \frac{426}{5}$

$\bar x = 85.2$

The mean absolute deviation (M) is:

$M = \frac{1}{n}\sum|x - \bar x|$

So, we have:

$M = \frac{1}{5}(|98 - 85.2|+|78 - 85.2|+|84 - 85.2|+|75 - 85.2|+|91 - 85.2|)$

$M = \frac{1}{5}(|12.8|+|-7.2|+|-1.2|+|-10.2|+|5.8|)$

Remove absolute brackets

$M = \frac{1}{5}(12.8+7.2+1.2+10.2+5.8)$

$M = \frac{1}{5}*37.2$

$M = 7.44$

Y={1 if x is rational 0 if x is irrational How would you describe it's graph?

Setler [38]

The set of rational plus irrational numbers equals ALL REAL NUMBERS

Yes, it is a function because every x-value maps into only one y-value. In other words, because rational and irrational are mutually exclusive, x does not map into both 0 and 1

Domain is all real numbers.

Range is 0 or 1

y-intercept happens when x=0, so that is a rational number and y = 1

There are an infinite number of x-intercepts. Every irrational number is an x-intercept

Neither even or odd because it is not symmetric with either the y-axis or the origin.

The graph jumps between y=0 and y=1

9.4 Qiz Setting up and solving simultaneous equations B

stellarik [79]

Answer:

building block = 4cm

flag pole = 7 cm

Step-by-step explanation:

9b + f = 43

4b + f = 23

5b = 20

b = 4

16 + f = 23

23 - 16 = 7

f= 7

36 + 7 = 43
