Answer:
As per the statement:
Hawick is 15 miles south of Abbotsford, and Kelso is 17 miles east of Abbotsford.
Let H represents Hawick , A represents Abbotsford and K represents Kelso
See the diagram as shown below:
Distance of AH = 15 miles
Distance of AK = 17 miles.
We have to find the distance HK:
Using Pythagoras theorem;
then;
or
miles.
Therefore, the distance from Hawick to Kelso( to the nearest tenth place) is 22.6 miles
Answer:
Yes, it is not a diameter
Step-by-step explanation:
It's going through the circle (sphere) which makes it a diameter
I and D are not going straight through the middle
Answer:
m<4 = 52°
m<BFD = 98°
Step-by-step explanation:
m<1 = (3x)°
m<2 = (5x - 7)°
m<3 = (4x + 15)°
m<AFD = 128°
✔️Find m<4:
m<4 = 180° - m<AFD (angles on a straight line)
Substitute
m<4 = 180° - 128°
m<4 = 52°
✔️m<BFD = m<2 + m<3
Substitute
m<BFD = (5x - 7)° + (4x + 15)°
We need to find the value of x.
Create an equation to find x.
m<1 + m<2 + m<3 = m<AFD (angle addition postulate)
Substitute
3x + 5x - 7 + 4x + 15 = 128°
Add like terms and solve for x
12x + 8 = 128
12x + 8 - 8 = 128 - 8
12x = 120
12x/12 = 120/12
x = 10
m<BFD = (5x - 7)° + (4x + 15)°
Plug in the value of x
m<BFD = 5(10) - 7 + 4(10) + 15
m<BFD = 50 - 7 + 40 + 15
m<BFD = 98°
Answer:
Step-by-step explanation:
1. The independent variable in this experiment would be the separation of students into distinct groups based on standardized tests of ability and achievement.
2. To implement the independent variable, the experimenter needs to divide the 100 volunteers into separate groups based on standardized tests of ability and achievements. He must also make sure that each groups’ students’ ability levels are the same. Then they would be given tasks as per their ability level.
3.The dependent variable here would be the academic achievements of the groups formed based on ability.
4. First, the volunteers’ achievement would be tested. Then based on their abilities as per standardized tests, they would be divided into groups of students with similar abilities. Then they would be given tasks as pr their abilities. Finally, their achievements would be measured to see if there is any significant difference in achievement between them before and after the grouping as per ability.
5.
6. Null Hypothesis: There would be no significant difference between the academic achievements in high school students of varying abilities due to separation into distinct groups based on standardized tests of ability and achievement.
Alternative Hypothesis: There would be a significant difference between the academic achievements in high school students of varying abilities due to tracking.
