Yes, because each input value corresponds to exactly one output value.Yes, because the outputs increase as the inputs increase.No, because the graph is not continuous.No, because the curve indicates that the rate of change is not constant.

-2.1 and 0.2
Answer: 0.1122
Step-by-step explanation:
Let A denotes the event that it snows in Greenland.
Then A' denotes the event that it does not snow in Greenland.
Let G be the event that glaciers grows.
Given : Suppose that it snows in Greenland an average of once every 27 days.
i.e.
Then,
Also, P(G|A)=0.23 and P(G|A')=0.07
By Bayes theorem , we have
Hence, the probability that it is snowing in Greenland when glaciers are growing= 0.1122
The question is incomplete, the complete question is;
A grocer has 18 kg of black tea worth $3.5 per kg. She wants to mix it with green tea worth $2.6 per kg to sell the mixture at $2.9 per kg. How much of green tea should she use?
Answer:
36
Step-by-step explanation:
Let the weight of the green tea used be x kg.
From the question:
We have:
18 kg of black tea at $ 3.5 per kg. Thus total cost of black tea is 18 x 3.5 = $ 63
Cost of green tea is $2.6 per kg. Total cost of green tea is 2.6 * x = $2.6x
Total weight of the mixture is 18 + x kg.
Total cost of the mixture is = $2.9 (18 + x)
Thus,
Total cost of black tea + total cost of green tea = Total cost of the mixture
$63 + $2.6 x = $2.9 (18 + x)
$63 + $2.6x = $52.2 + $2.9x
63 – 52.2 = 0.3 x
10.8 = 0.3 x
x = 10.8/0.3
x = 36
36 kg of green tea is needed
Answer:
Steps to Construct a Perpendicular Bisector of line segment are as follows:
Step 1 : Draw the line segment of given
length or any length.
Step 2 : With W as center, using compass, draw a circle ( or two
arcs one above line and one below line ) . The radius of
circle ( or arcs ) should be more than half the length of
.
Step 3 : With the same radius and with X as center, draw
another circle (or arcs) using compass. Let it cut the
previous circle (or arcs) at A and B.
Step 4 : Join . It cuts at O.
Therefore, is perpendicular bisector of
