Answer:

Hope that help the answer is 300

Step-by-step explanation he drives for 3 hours at a rate of 80 km per hour, multiply:

Now we need to find how far he goes in 45 minutes. There are 60 minutes in an hour, so write and simplify:

45 is three quarters of an hour, so multiply that by 80 km per hour:

Add the distances together:

At a rate of 80 km per hours, in 3 hours and 45 minutes, Tim drives 300 km.

Answer:

300 km

Step-by-step explanation:

If he drives for 3 hours at a rate of 80 km per hour, multiply:

80*3=240

Now we need to find how far he goes in 45 minutes. There are 60 minutes in an hour, so write and simplify:

\frac{45}{60}=\frac{3}{4}

45 is three quarters of an hour, so multiply that by 80 km per hour:

\frac{3}{4}*80\\\\\frac{3*80}{4}\\\\  \frac{240}{4} =60

Add the distances together:

60+240=300

At a rate of 80 km per hours, in 3 hours and 45 minutes, Tim drives 300 km.

<em>Finito.</em>

Given: is an angle bisector of ∠JMK<br><br><br>Prove: m
astraxan [27]

Answer:

An angle bisector is a line passing through the vertex of the angle that cuts the angle into two equal smaller angles.

Given: MN is angle bisector,

then  

\angle JMN \cong \angle NMK            .......  [1]

Congruent angles are  two or more angles that have the same measure.

then;

by definition of congruent angles

[1]⇒ m\angle JMN = m\angle NMK                ......[2]

By the  Angle addition postulates states that if M is in the interior of ∠JMK then,

m\angle JMN+m\angle NMK =m\angle JMK            ......[3]

Now, by substitution property ; substitute the equation [2] in [3] we get;

m\angle JMN+m\angle JMN =m\angle JMK                 ......[4]

Like terms terms whose variables  are the same

Combine like terms in equation [4] we get

2 \cdot m\angle JMN=m\angle JMK                      ......[5]

Division property of equality states that you divide the same number to both sides of an equation.

Divide by 2 to both sides in equation [5] , we get

m\angle JMN= \frac{1}{2} m\angle JMK

a class with 30 students had an average score of 80 on a test. A class with 20 students had an average score of 90 on the same t
snow_tiger [21]

The average score of all the students in both classes is 84.

<h3>How to calculate the average?</h3>

The class with 30 students had an average score of 80 on a test. The total score will be:

= 30 × 80

= 2400

A class with 20 students had an average score of 90 on the same test. The total score will be:

= 20 × 90

= 1800

Total scores = 2400 + 1800 = 4200

Number of students = 20 + 30 = 50

The average score will be:

= Total score / Total students

= 4200 / 50

= 84

How do I construct a sample data set for which n=7, x=9(x bar), and s=0?
JulijaS [17]
When the standard deviation = 0, there is no deviation at all. So the numbers are all the same. And there are seven of them. And the average is nine. 
So the sample data set would just be seven 9s.
