Mathematics
1 answer:
Mademuasel [1]3 years ago
4 0

Answer:

0.84

Step-by-step explanation:

From the given histogram we can state that

  • P(x=1)=0.32;
  • P(x=2)=0.24;
  • P(x=3)=0.28;
  • P(x=4)=0.16.

Note that the probability

P(1\le x\le 3)=P(x=1)+P(x=2)+P(x=3)=0.32+0.24+0.28=0.84.

A 14 gram sample of a substance that's used to preserve fruit and vegetables has a k-value of 0.1092. Find the substance's half-
nignag [31]

Answer:

t = 6.3

Step-by-step explanation:

N=Noe^(-kt)

No = 14 grams

k = .1092

We want to find t when N = 7 or 1/2 of 14

N=Noe^(-kt)

7 = 14 e ^ (-.1092t)

Divide each side by 14

1/2 = e ^ (-.1092t)

take the natural log of each side

ln (1/2) = ln e ^ (-.1092t)

ln (1/2) = -.1092t

Divide each side by -.1092

ln (1/2)/ -.1092 = t

t≈6.3475

Rounding to the nearest tenth

t = 6.3
