Answer:
80 Strawberries
Step-by-step explanation:
If she picked 120 strawberries in 6 hours
Then in 1hour she picked 120/6 = 20 strawberries
Then in 4 hours she picked 20×4 = 80 strawberries
Answer:
The third figure is the answer (Look to the attached figure
Step-by-step explanation:
* The point of symmetry means
- If a figure or graph can be rotated 180° about a point P
and end up looking identical to the original, then P is a point
of symmetry
- The same distance from the central point
but in the opposite direction.
* Lets look to the four answers
- In the 3rd figure first line up can be rotated 180° about a point P
and end up looking identical to the second line down, then P
is a point of symmetry
- The same distance from the point p
but in the opposite direction.
* The figure show the answer
Answer:
a) Scores of 2 and higher are significantly high
b) Scores of -2 and lower are significantly low
c) Scores between -2 and 2 are not significant.
Step-by-step explanation:
Mean = 0
Standard deviation = 1
a. significantly high (or at least 2 standard deviations above the mean).
2 standard deviations above the mean is:
0 + 1*2 = 2
So scores of 2 and higher are significantly high
b. significantly low (or at least 2 standard deviations below the mean).
2 standard deviations below the mean is:
0 - 1*2 = -2
So scores of -2 and lower are significantly low
c. not significant (or less than 2 standard deviations away from the mean).
2 standard deviations above the mean is:
0 + 1*2 = 2
2 standard deviations below the mean is:
0 - 1*2 = -2
So scores between -2 and 2 are not significant.
7) -5-x=0
x=-5
8) 4x-36=0
4(x-9)=0
x-9=0
x=9
Solve for z
3z+4=34
Subtract 4 from both sides.
= 3z=30
Divide both sides by 3
z=10
Hope I helped! :D
