The range of milk production that 95% of the cows will fall within is option B: 4.8 gallons to 7.6 gallons.
To find the range of daily milk production that 95% of the cows will fall within, we can use the empirical rule, which states that for a normal distribution:
About 68% of the observations fall within one standard deviation of the mean.
About 95% of the observations fall within two standard deviations of the mean.
About 99.7% of the observations fall within three standard deviations of the mean.
Since we are looking for the range of milk production that 95% of the cows will fall within, we need to find the range that is within two standard deviations of the mean. That range is:
Mean ± 2SD
= 6.2 ± 20.7
= 6.2 ± 1.4
= [4.8, 7.6]

First, find 12 percent of 1,150,
12 percent of 1,150 = 138.
Now, add 1,150 + 138,
1,150 + 138 = 1,288

Answer:
x=37, Angle A is 74. Exterior angle B is 185
Step-by-step explanation:
I'm pretty sure this right but This is a triangle that is folded to the inside. This means that most likely there is a negative interior degree
angle. Using the interior theorem, we can add up all the non adjacent sides to find the exterior angle of the adjacent side. 79+2x+32=5x, 2x+111=5x, 111=3x, x=37. Then plug 37 in for x Angle A is 74 degree and B exterior angle Is 185 degree.

To compute the perimeter of a rectangle, you add the length, l , and width, w , and double this sum.
This means you can find the perimeter of a rectangle by evaluating the expression 2 (1 + w ).
Use this expression to find the perimeter of a rectangle with length 30 and width 75.
210 (A)
135 (B)
180 (C)
107 (D)
Answer:
210 (A)Step-by-step explanation:
Use the formula:
P = 2(l + w)Substitute the values and find P:
P = 2(30 +75) = 2(105) = 210Correct choice is A
Answer:
given length [l]=30
width[w]=75
perimeter= 2 (l + w )=2(30+75)=210
so
answer is A.210

find the missing length indicated
Answer:
15
Step-by-step explanation:
Answer:
21
Step-by-step explanation:
It is given that two lines are parallel, and hence the corresponding angles are congruent, by corresponding angles postulate. It is also given that the triangles in the photo share an angle, by the reflexive property, the shared angle is congruent. Hence one can use angle-angle to determine that the two triangles in the picture are similar.
Using this, one can set up a proportion with the sides. The ratios of any two corresponding sides are the same as any other two corresponding sides in the triangle, respectively, this is due to the corresponding parts of similar triangles theorem.

Write in Slope Intercept form
Answer:
y=5/2x
Step-by-step explanation:
the y intercept is (0,0) so it isn't included in the equation. now we know the middle solution isn't correct. the points we use to find slope are (-2,-5) and (2,5) which ends up being 5/2.

Step-by-step explanation:
Answer and Explanation:
Problem 1:
4x - 12 = 16
4x = 28
x = 28 / 4
x = 7, G
Problem 2:
5x + 10 = - 25
5x = - 35
x = - 35 / 5
x = -7, C
Problem 3:
x / 2 + 11 = 12
x / 2 = 12 - 11 = 1
x = 2 * 1
x = 2, H
Problem 4:
