Answer:
50*0.60 or 0.6
Step-by-step explanation:
Since percent is a representation of 1/100, you can use a decimal.
Since 60 percent is 60/100, and 60/100 is equal to 0.60 or 0.6, the 0.6 part of the equation is correct.
And since there is 50 animals, you can multiply this number 0.60, by 50, for the 60 percent.
So, the answer is 50*0.6.
Hope this helps. Have a nice day
Answer:
B
Step-by-step explanation:
(1 1/2,-2)
solve for x and get 1 1/2
solve for y and get -2
D. 11.0% compounded continuously
The probability that a student scored less than 55% on the exam is 0.134%.
<h3>What is a normal distribution?</h3>
It's the probability curve of a continuous distribution that's most likely symmetric around the mean. On the Z curve, at Z=0, the chance is 50-50. A bell-shaped curve is another name for it.
We have:
Mean of the sample = 70
Standard deviation = 5
= P(X<55%)
Z = (55-70)/5
Z = -3
P(X < -3)
From the Z table:
P(x<-3) = 0.0013499
or
P(x<-3) = 0.134%
Thus, the probability that a student scored less than 55% on the exam is 0.134%.
