Consider the plane T. and three collinear (but not coplanar) points P, Q, and W.
Can either P, Q, or Wbe a point on the plane T?
A Yes, because if points are collinear, they must all fall on the same plane and be coplanar.
B Yes, because even if points are collinear, one of the points may fall on a plane while the others do not.
C No, because if points are collinear, they must all fall on the same plane and be coplanar.
D No, because even if points are collinear, one of the points may fall on a plane while the others do not.

TWO points A and B on a plan represent two localities 12 m apart. Given that the segment AB is 6 cm long, find the scale used to draw the plan.
Answers
Answer:
The scale used to draw the plan is 1: 200.
Step-by-step explanation:
Given that two points A and B on a plan represent two localities 12 m apart, to determine, given that the segment AB is 6 cm long, the scale used to draw the plan, the following calculation must be performed:
12 m = 12 cm x 100 = 1200 cm
1200/6 = 200
Therefore, the scale used to draw the plan is 1: 200.

A sample of 23 women athletes, aged 20 was taken. The systolic blood pressure of these women had an average of 112 with a standard deviation of 3.3. Calculate a 90% confidence interval for the average systolic blood pressure of 20-year old women athletes.
Answers
Answer:
Step-by-step explanation:
average of 112 with a standard deviation of 3.3. Calculate a 90% confidence interval for the average systolic blood pressure of 20-year old women athletes.
From the above question
Number of samples = 23 , less than 30,
Hence, we find confidence interval using t score
Confidence Interval using t score =
Mean + t score × standard deviation/√n
Step 1
We find the degree of freedom
= N - 1
= 23 - 1

5. Given AADL AAKM with AD = 14, DK = 21, and
AL= 15. What is the measure of LM?
Answers
Answer:
22.5
Step-by-step explanation:
first of all, the first sign in the designations of the triangles is not an A. it is the Greek Delta (capital) sign. standing for "triangle" due to its shape.
as the diagram shows (and the description says correctly), ADL and AKM are similar triangles.
that means they have the same angles.
and in order to keep the same angles even when the lengths of the sides are different, the relative relation of the side lengths must be the same for all sides.
that means, if one side changes by a factor f, then both other sides must change by the same factor.
so, by checking the change factor for AD (to AK), we can then determine the change of AL to AM. and then we simply subtract AL from AM and get LM.
the original AD = 14.
AK = AD + DK = 14 + 21 = 35
the change factor f is then AK/AD = 35/14 = 5/2
in other words AD grew by a factor of 5/2.
AM is then created by applying the same factor to AL.
=> AM = 15 * 5 / 2 = 75 / 2 = 37.5
=> LM = AM - AL = 37.5 - 15 = 22.5

Shawn has a bank account with $3,069. He decides to invest the money at 3.25% interest, compounded annually. How much will the investment be worth after 5 years? Round to the nearest dollar.
Answers
F (3)=300×(1.02)^(3)=318.36
The value of his investment at the fifth year is
F (5)=300×(1.02)^(5)=331.22
The average rate of change of the value is
(331.22−318.36)÷2 years=6.43 per year
The investment worth after 5 years to the nearest dollar will be $3601.
What is compound interest?We know that the compound interest is given as
A = P(1 + r)ⁿ
Where A is the amount, P is the initial amount, r is the rate of interest, and n is the number of years.
Shawn has a bank account with $3,069. He decides to invest the money at 3.25% interest, compounded annually.
The worth of investment after 5 years is calculated as,
A = $3,069 x (1 + 0.0325)⁵
A = $3,069 x 1.0325⁵
A = $3,069 x 1.1734
A = $3601
The investment worth after 5 years to the nearest dollar will be $3601.

Laurie is painting the walls of her kitchen. It took Laurie 3 hours to paint 20% of the walls in her kitchen. How many total hours did Laurie take to paint the walls of her kitchen?
Answers
Answer:
Total time taken by Laurie to cover all kitchen walls = 15 hours
Step-by-step explanation:
Given:
Time taken by Laurie to cover 20% of kitchen walls = 3 hours
Find:
Total time taken by Laurie to cover all kitchen walls
Computation:
Total time taken by Laurie to cover all kitchen walls = Time taken for 20%[100%/20%]
Total time taken by Laurie to cover all kitchen walls = 3[10/2]
Total time taken by Laurie to cover all kitchen walls = 3[5]
Total time taken by Laurie to cover all kitchen walls = 15 hours

Carlos and his family left for the amusement park at 8:35 Ask Your Teacher The trip took 1 hour 55 minutes. What time did they arrive?
Answers
Answer:Carlos and his family arrived at 10:30
Step-by-step explanation:
The time Carlos and his family left for the amusement park =8:35
Since The trip took 1 hour 55 minutes., we have to add it to the time they left for the amusement park to now the time they arrived
8: 35 =8 hrs 35minutes
1 hr 55 minutes
90 minutes
but 90minues is greater than 60 so we convert to hours and minutres by dividing by 60 giving us
90/60=1.5hrs=1hr 30mins
8¹ hrs 35minutes
1 hr 55 minutes
10hrs 30 minutes
Therefore, They arrived at 10:30

What is the slope of the line that passes through the points (26, 7) and (-39, 12)?
Answers
Answer:
Step-by-step explanation:
point P1 = (26,7) in the form (x1,y1)
point P2 = (-39,12) in the form (x2,y2)
slope , m , of a line is:
m = (y2 - y1) / (x2 - x1)
m = (12-7) / ( -39-26)
m = 5 / -65
m = - 1 / 13
