Answer:
y = x + 4
Step-by-step explanation:
For a line to be Parallel it has to have the same slope but different y intercept
Answer:
0.9962
Step-by-step explanation:
The z score shows the number of standard deviations by which the raw score is above or below the mean. If the raw score is above the mean then the z score is positive but if the raw score is less than the mean then the raw score is negative. The z score is given by:

μ = 20.66°C, σ = 2°C
For x < Singapore temperature, i.e. x < 26

From the normal distribution table P(x < 26) = P(z < 2.67) = 0.9962
4. Number is 3
I don’t got time to do other ones. Sorry
X intercept is when y = 0
y = 3x + 12
0 = 3x + 12
3x + 12 = 0
3x = 0 - 12
3x = -12
x = -12/3
x = -4
x intercept is = -4.
F=ir^t, f=final amount, i=initial amount, r=common ration or "rate", t=times common ration is applied or "time", in this case:
1200=1000r^2 divide both sides by 1000
1.2=r^2 take the square root of both sides
1.2^(1/2)=r so the equation is:
f=1000(1.2)^(t/2), so in 13 hours
f=1000(1.2)^(13/2)
f=1000(1.2)^(6.5)
f≈3271 bacteria (to the nearest whole number)
