Mathematics
1 answer:
Ivanshal [37]2 years ago
6 0

Answer:

1.2

Step-by-step explanation:

First, you cancel out \frac{6}{20} to become \frac{3}{10}

Then that becomes -\frac{3}{10}+1.5

Now, you convert the element to a decimal form to be -0.3+1.5

Finally, you subtract them (because a negative plus a positive is subtraction) to get the final answer of 1.2

Hope this helps!

A graph that uses bars of various heights to represent the frequencies.
Sunny_sXe [5.5K]

A graph that uses bars of various heights to represent the frequencies is a <u>Histogram</u>

A histogram is an approximate representation of the distribution of numerical data. The term was first introduced by Karl Pearson. To construct a histogram, the first step is to "bin" (or "bucket") the range of values—that is, divide the entire range of values into a series of intervals—and then count how many values fall into each interval.

Therefore, a graph that uses bars of various heights to represent the frequencies is a <u>Histogram</u>

The sum of the measures of the angles of a triangle is 180. The sum of the measures of the second and third angles is five times
erastova [34]

Answer:

first angle be 30°

second angle be 70°

third angle be 80°

Step-by-step explanation:

first angle be x

second angle be y

third angle be z

x+y+z=180

given, y+z = 5x; z=5x-y

also, z=y+10

5x-y = y+10

5x= 10+y+y = 10+2y

x= (10+2y)/5

x+y+z=180

(10+2y)/5 + y + y+10 = 180

(10+2y)/5 = 180 -2y -10

(10+2y)/5 = 170-2y

multiply both sides by 5

10+2y = 5(170-2y)

10+2y= 850-10y

2y+10y = 850-10

12y= 840

y= 840/12 = 70°

z=y+10 =70+10= 80°

5x= (10+2y) = 10+2(70) = 10+140= 150

x = 150/5 = 30°
