Answer:
Hello your question is incomplete attached Below is the missing histogram
answer: 10 map squares
Step-by-step explanation:
There are 10 map squares that did survive more than 29 pant species because from the given diagram we can see that the plant species above 29 are spotted in 4 map squares ( i.e. from spot 30 to 39 ) and 6 map squares ( i.e. from 30 to 49 )
hence the total number of map squares = 4 + 6 = 10 map squares
A) n + d = 20
B) .05n + .10d = 1.40 Multiplying A) by -.10
A) -.1n -.1d = -2 Then adding it to B
B) .05n + .10d = 1.40
-.05n = -.60
n = 12 nickels
d = 8 dimes
Answer:
0 ≤ u < 7 and 0 > u > - 7 and combining those two we get - 7 < u < 7.
Step-by-step explanation:
The given inequality is |u| - 2 < 5 ....... (1)
We have to solve this inequality.
Now, from the definition of f(x) = |x| we get, f(x) = x, when x ≥ 0 and
f(x) = -x when x < 0.
Hence, for u ≥ 0, the equation of inequality (1) becomes
u - 2 < 5
⇒ u < 7
Therefore, the solution is 0 ≤ u < 7 (Answer)
Again, for u < 0, the equation of inequality (1) becomes
- u - 2 < 5
⇒ u + 2 > - 5
⇒ u > - 7
Therefore, the solution becomes 0 > u > - 7 (Answer)
