Answer:

Step-by-step explanation:

Find the LCM of 30 & 20

30 =  2 * 5 * 3

20 = 2 * 2 * 5

LCM = 2 * 3 * 2 * 5 = 60

60 minutes = 1 hour

So, again at 10am both will leave at the same time

Answer:

11 am.

Step-by-step explanation:

That would be the LCM of 20 and 30 which is 60 minutes.

So the nexrt time will be 10.00 + 60 mins

= 11.00 am.

Answer:

The answer is "0.36".

Step-by-step explanation:

we assume, that they are not blood-relatives, then we need both the dates (birth and death)

Births between 1512 and 2012 may occur at any time, and all of the math forms are what we have to be born at least 100 years apart.

Pr(Mathematician 1 is born inside an interval of 1512-2012 on a particular year)= [tex]\frac{1}{50000}[/tex])

Mathematician 2 born in 1512-2012 interval on every specific year) = [tex]\frac{1}{50000}[/tex]

S Year of birth'

After that, We need to find all of the years of absolute value (birth the year Mathematician 1-birth year of Mathematician 2) <= 100 or give the probability of this happening.

Prob(Mathematician 1 birth between 1512-2012 in a specific group of 100 years):

[tex]\to \frac{100}{500}=\frac{1}{5}[/tex]

For just a mathematician, are using the same rationale 2.

By using fact for freedom now Pr(that the dual births are divided by 100 years)) = 1-Pr(they are divided by more than 100 years):

[tex]\to 1- (\frac{400}{500})^2 \\\\\to 1- (\frac{4}{5})^2 \\\\\to 1- \frac{16}{25}\\\\\to \frac{25 -16}{25}\\\\\to \frac{9}{25}\\\\\to 0.36[/tex]

Answer:

25

Step-by-step explanation:

3x - 5 = 2x + 20 ( corresponding angles)

3x - 2x = 20 + 5

x = 25

Answer:

14.2 years

Step-by-step explanation:

The town grows 4% (0.04) every year.

3000 x 0.04 = 120, so the town gains 120 people every year.

The town needs 1700 more people to get to 4700.

So, 4700/120= 14.1666666667

That rounds up to 14.2 years.

Answer:

a = 3, b = 5, and c = 1.

what is ac + b=8 answer

Step-by-step explanation:

a(c)+b

3(1)+5

3+5= 8

The required solution is 8 when substituting the values of a = 3, b = 5, and c = 1.

Algebraic expressions are mathematical statements with a minimum of two terms containing variables or numbers.

The expression is given in the question, as follows:

ac + b

We have to determine the evaluation when a = 3, b = 5, and c = 1.

As per the question, we have

⇒ ac + b

Substitute the values of a = 3, b = 5, and c = 1 n the above expression,

⇒ 3(1) + 5

⇒ 3 + 5

Apply the addition operation, and we get

⇒  8

Thus, the required solution is 8.

Answer:

Mean:29.25

Median:25

Mode:25

Outlier:69

Range:53

Step-by-step explanation:

mean: 18+69+22+27+32+25+16+25/8=29.25

median: put in order: 16+18+22+25+25+27+32+69

middle is 25+25/2 which is 25.

median:25.

Mode = 25.

Outlier = 69.

Range is 69-16=53

Hope this helps :) pass your test :)

Answer:

mean = 29.25

median = 25

mode = 25

outlier = 69

range = 53

Step-by-step explanation:

Mean: add all values and divide by number of values   234 ÷ 8

Median: middle value if there are an odd number of data values, or the average of the two middle values if there are an even number of data values    

Mode:  data item seen most often

Outlier = data value that is extreme

Range = Highest value minus lowest value

Answer: 80°; the supplementary angle to the 30° angle and ∠1 is a corresponding angle to the 70° angle this means that the supplementary angle to the 30° angle and ∠1 is a 70° angle therefore 30°+m ∠1+ 70° equals 180°. So, m ∠1= 180°.

Step-by-step explanation:

The measure of angle 1 should be 80 degrees.

Two angles whose sum is 180° are called supplementary angles. If a straight line is intersected by a line, then there are two angles form on each of the sides of the considered straight line. Those two two angles are two pairs of supplementary angles.

Then its meaning; supplementary angles are aligned adjacent to each other, and their exterior sides will make a straight line.

The supplementary angle to the 30° angle and ∠1 is a corresponding angle to the 70° angle which means that the supplementary angle to the 30° angle and ∠1 is a 70° angle.

Therefore 30° + m ∠1 +  70° = 180°.

100 + m ∠1= 180°.

So, m ∠1= 80°.
