Could it be 12? Difference between 16-13=3, 13-7=6. 4-3=1, 3-1=2. Seems as if for each column, difference between first and second row is one half the difference between the 2nd and third rows
Answer:
p(blue or red) = 0.52 = 52%
Step-by-step explanation:
total number of marbles = 7 + 10 + 14 + 19 = 50
number of blue marbles = 7
number of red marbles = 19
number of blue or red marbles = 7 + 19 = 26
p(blue or red) = 26/50
p(blue or red) = 0.52 = 52%
Begin by using the cosine rule to find the unknown side.
Where a- unknown side, b is 12, c is 16 and angle in between is 108°
The cosine rule...
a² = b² + c² - 2bc cosA
= 12² + 16² - (2×12×16 cos108°)
= 518.655076
Taking the positive
square root...
a = 22.774
a = 22.8 cm nearest tenth
A. 0.250006, 0.250007, 0.250008
b. 0.3330001, 0.3330002, 0.3330003
Answer:
| x - 0 | ≤ 2
Step-by-step explanation:
Given,
The ideal temperature of the freezer = 0° F,
Also, it can fluctuate by 2° F,
Thus, if x represents the temperature of the freezer,
Then, there can be two cases,
Case 1 : x > 0,
⇒ x - 0 ≤ 2
Case 2 : If x < 0,
⇒ 0 - x ≤ 2,
⇒ -( x - 0 ) ≤ 2,
By combining the inequalities,
We get,
| x - 0 | ≤ 2,
Which is the required inequality.
