Mathematics
1 answer:
Ray Of Light [21]3 years ago
3 0

Answer:

Step-by-step explanation:

11.

f(-8) = (-3/2)(-8) +11 = (24/2) +11 = 12+11 = 23

12.

g(-2) substitute x by -2 in the g( x) equation

9(-2) = (-2)²-7(-2) = 4 +14 = 18

13.

h(2/3) = | 15 -9(2/3)| = | 15 -(18/3)| = | 15 -6 | = |9| = 9

12.

the zero is at x= -2 because is the intersection of the graph with the x-axis

13.

the zero are at x=1, x= -2, x= -4 because is the intersection of the graph with the x-axis

Find a so that the point (1,2) is on the graph of f (x)=ax^2+5
12345 [234]
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 :)

Farmers often sell fruits and vegetables at farmers’ markets during the summer. Each tomato stand at the Bentonville farmers’ ma
olga nikolaevna [1]

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%)
