The y intercept is where the line crosses the y axis or where x=0
basically f(0) which is 1000 or B
the y intercept is when x=0, when time=0, so it represents the amount of cicadas initially on the farm
the 2 means it doubles every week (because x=number of weeks)
B
A
C
Ionic bonding is present for potassium chloride. Two opposite ions attract and for a bond called the ionic bond. On the other, sucrose has a covalent bonding where electrons are shared between atoms. Between this two bonds, ionic is the much stronger bond therefore the correct answer is the first option. Potassium chloride has a higher boiling point than sucrose.

Estimate: 200 x 4 = 800
Answer: the probability that she will be between 65 and 67 inches tall is 0.2077
Step-by-step explanation:
Since heights of women in the United States are normally distributed, we would apply the formula for normal distribution which is expressed as
z = (x - µ)/σ
Where
x = heights of women.
µ = mean height
σ = standard deviation
From the information given,
µ = 63.7 inches
σ = 2.7 inches
We want to find the probability that the height of a woman selected will be between 65 and 67 inches. It is expressed as
P(65 ≤ x ≤ 67)
For x = 65,
z = (65 - 63.75)/2.7 = 0.46
Looking at the normal distribution table, the probability corresponding to the z score is 0.6772
For x = 67,
z = (67 - 63.75)/2.7 = 1.2
Looking at the normal distribution table, the probability corresponding to the z score is 0.8849
P(65 ≤ x ≤ 67) = 0.8849 - 0.6772
= 0.2077
