Answer:
The probability is 0.683
Step-by-step explanation:
To calculate this, we shall be needing to calculate the z-scores of both temperatures
mathematically;
z-score = (x-mean)/SD
From the question mean = 78 and SD = 5
For 73
z-score = (73-78)/5 = -5/5 = -1
For 83
z-score = (83-78)/5 = 5/5 = 1
So the probability we want to calculate is within the following range of z-scores;
P(-1 <z <1 )
Mathematically, this is same as ;
P(z<1) - P(z<-1)
Using the normal distribution table;
P(-1<z<1) = 0.68269 which is approximately 0.683
Answer:
3(x−4)(x+2)
Step-by-step explanation:
2 / 0.08 = 25
<span>Therefore, 8 percent of 25 is 2.</span>
The answer is 42
first change the numbers from scientific notations into numbers.
1.47*10^7= 14700000
3.5*10^5= 350000
now divide the number of sweets by the number of packets. the quotient is the answer
14700000/350000= 42
good luck
