Answer:
y=-7x+4
Step-by-step explanation:
we konw that it's slope is -7,so we get the dy/dx is -7 and the line must be a linear fuction. So we can get f(x)=-7x+C and wu can substitute the point (0,4) they give us. Then we can get C=4
This means that you are in the experiment group
It is common to choose a group of people to study the effect of certain things like the one given in this question. The selection of people is done after designing the sample size for a certain population. The design varies depending on whether the analysis is qualitative or quantitative.
The people who lie in the sample size actually contribute to the experiment are said to be part of it.
Therefore, if you are part of the study that is used to test the effectiveness of a new drug for treating the common cold. It means you are part of the experiment group.

Volume of the spherical tank will be given by:
V=4/3πr³
thus the volume of the tank will be:
V=4/3×π×(10/2)³=523.59877756~523.6 ft³
Given that 523.6 ft³ can hold 358,000,000 BTUs of propane, the amount that 1 ft³ will be given by:
[total amount]/[total volume]
=358,000,000/523.6
=683,728.0367 BTUs/ft³
=684,000 BTUs/ft³ (in thousand)

Answer:
$2.00
Step-by-step explanation:
$1.20÷3=0.40
therefore a pound of tomatoes is for $0.40¢
so 5lbs is for: 5×0.40
=$2.00
