Answer:
Photosynthesis equation
Step-by-step explanation:
Answer:
2x-5=4
2x=9
x=9/2=4.5
or
2x-5=-4
2x=1
x=1/2
Step-by-step explanation:
1/3x + 5 = -2 is the way to set up the equation…. You got this!
Answer: a = -5
Heyy, so with this question you would have to substiute 1 for x because normally the coordinates have x first then y. E.g. (x,y)
soo, f(1) = a(1)^2 +5
then, f(1) = a + 5
then equate to zero. E.g. a+5=0
then move over 5 to other side E.g. a=-5
soo.. yah.. pretty sure haha :)
Answer:
the probability that all tomatoes are sold is 0.919 (91.9%)
Step-by-step explanation:
since the random variable X= number of tomatoes that are demanded, is normally distributed we can make the standard random variable Z such that:
Z=(X-μ)/σ = (83 - 125)/30 = -1.4
where μ= expected value of X= mean of X (since X is normally distributed) , σ=standard deviation of X
then all tomatoes are sold if the demand surpasses 83 tomatos , therefore
P(X>83) = P(Z>-1.4) = 1- P(Z≤-1.4)
from tables of standard normal distribution →P(Z≤-1.4)=0.081 , therefore
P(X>83) = 1- P(Z≤-1.4) = 1 - 0.081 = 0.919 (91.9%)
thus the probability that all tomatoes are sold is 0.919 (91.9%)
