Answer:
Probability that a randomly selected pregnancy lasts less than 233 days is 0.3594.
Step-by-step explanation:
We are given that the lengths of the pregnancies of a certain animal are approximately normally distributed with mean mu equals 238 days and standard deviation sigma equals 14 days.
Let X = <u><em>lengths of the pregnancies of a certain animal</em></u>
So, X ~ Normal(
)
The z score probability distribution for normal distribution is given by;
Z = 
~ N(0,1)
where, 
= population mean = 238 days
= standard deviation = 14 days
Now, the probability that a randomly selected pregnancy lasts less than 233 days is given by = P(X < 233 days)
P(X < 233 days) = P( < 
) = P(Z < -0.36) = 1 - P(Z 
0.36)
= 1 - 0.6406 = 0.3594
The above probability is calculated by looking at the value of x = 0.36 in the z table which has an area of 0.6406.
Answer:
14
Step-by-step explanation:
1/2bh is saying that the base times the height, halved is the area of the triangle.
so
we will do the base times the height
7x4=28
then we will halve it
28/2=14
the answer is 14
I think the answer is D, I've been told it's D by many people.
A table can be represented with a linear function equation as y = mx + b, where m is the slope and b is the y-intercept.
<h3>How to Represent a Table with Linear Function?</h3>
Assuming we have a table of values as shown in the image attached below, to write an equation of linear function for the table, do the following:
Pick two pairs of values, say, (1, 5) and (2, 25) and find the slope (m):
Slope (m) = change in y / change in x = (25 - 5)/(2 - 1)
Slope (m) = 20
Find the y-intercept (b) by substituting (x, y) = (1, 5) and m = 20 into y = mx + b:
5 = 20(1) + b
5 = 20 + b
5 - 20 = b
-15 = b
b = -15
Write the equation of the linear function by substituting m = 20 and b = -15 into y = mx + b:
y = 20x - 15

Answer:
2
Step-by-step explanation:
Each time you flip a coin, there is a 50% change of it landing on tails. So half the time you should get a tails.
Half of 4 is 2, so you will likely get 2 tails.
