Answer:
base edge? height?
Surface area of a square pyramid:
s = length of base edge.
h = height of pyramid from base to top.
A = surface area.
[tex] A \: = s² + 2s \sqrt{\frac{a^{2}}{4}+h^{2}}[/tex]
√ = square root, root of 2, opposite of square.
² = square, power of 2, times itself once.
√n × √n = n
n × n = n²
Dairy farmers are aware there is often a linear relationship between the age, in years, of a dairy cow and the amount of milk produced, in gallons per week. The least-squares regression line produced from a random sample is . Based on the model, what is the difference in predicted amounts of milk produced between a cow of 5 years and a cow of 10 years
Complete question :
Dairy farmers are aware there is often a linear relationship between age, in years, of a dairy cow in the amount of milk produced, in gallons per week. The least squares regression line produced from a random sample is milk=40.8-1.1(Age). Based on the model, what is the difference in predicted amounts of milk produce between a cow of five years in a cow of 10 years?
Answer:
A cow of five years is predicted to produce 5.5 more gallons of milk per week.
Step-by-step explanation:
Given the regression model :
milk=40.8-1.1(Age)
Milk produced by 5 year old cow using the model :
Milk produced = 40.8 - 1.1(5)
Milk produced = 40.8 - 5.5
Milk produced = 35.3
Milk produced by 10 year old cow using the model :
Milk produced = 40.8 - 1.1(10)
Milk produced = 40.8 - 11
Milk produced = 29.8
Difference in volume of milk produced :
Age 5 milk producrion- Age 10 milk production :
35.3 - 29.8
= 5.5
Answer:
Answer B
Step-by-step explanation:
The difference of 5 years produces a 5.5 gallon per week difference in favor of the younger cow.

What’s the surface area in square units if right I’ll mark brainleiest
Answer: 349 square units
============================================
Work Shown:
L = 5.5 = lengthW = 5 = widthH = 14 = heightSA = surface area of rectangular prism
SA = 2*(L*W + L*H + W*H)
SA = 2*(5.5*5 + 5.5*14 + 5*14)
SA = 2*(27.5 + 77 + 70)
SA = 2*(174.5)
SA = 349
The surface area is 349 square units.
Answer:
The answer is 349
Step-by-step explanation:

-x/2+3/2<5/2
Answer:
3x
Step-by-step explanation:
Answer:
-x/2+3/2<5/2=
-x/2+3/2=5/2
subtracting 3/2 from both sides,
-x/2=2/2
simplifying, 2/2=1
-x/2=1
to get rid of the denominator of 2 you must multiply by 2. also to make the answer positive you must multiply both sides by -1,
therefore: x>-2

Are the two triangles above similar? Why or why not?
A. Yes, they are similar by the AA similarity postulate.
B. Yes, they are similar by the SAS similarity theorem.
C. No, there is not enough information given to prove similarity.
D. No, right triangles are never similar.
No, Triangles with one congruent angle are never similar so the correct option is D.
What is similar triangle?Similar triangles are triangles that have constant form, however their sizes might vary. All equal triangles, squares of any aspect lengths are samples of similar objects. In other words, if 2 triangles are similar, then their corresponding angles are congruent and corresponding sides are in equal proportion.
For AAA similarity postulate; Two triangles are similar if two corresponding angles of them are of same measure. It is because when two pairs of angles are similar, then as the third angle is fixed if two angles are fixed, thus, third angle pair also gets proved to be of same measure.
If the triangles, have only 1 congruent angles , it can not be said similar because for a triangle to be similar , minimum two criteria must be equal .
Hence we can conclude that triangles with one congruent angle are never similar.

Sana bought a dress for $32.99 and two purses. The total cost for the three items was $57.97. What was the cost for one purse?
Answer:
$12.49
Step-by-step explanation:
cost of two purses = $57.97 - cost of dress = $57.97 - $32.99 = $24.98
cost of one purse = $24.98 ÷ 2 = $12.49

Given this equation y = x2 + 2x -5 , Find the average rate of change over the interval 2 ≤ x ≤ 4 ?
Answer:
The average rate of change is 8.
Step-by-step explanation:
We are given the equation:
[tex]y=x^2+2x-5[/tex]
And we want to find the average rate of change on the interval [2, 4].
When finding the average rate of change, we essentially find the endpoints and then find the slope between them.
So, the endpoints are:
[tex]y(2)=(2)^2+2(2)-5=3[/tex]
And:
[tex]y(4)=(4)^2+2(4)-5=19[/tex]
So, the average rate of change between them is:
[tex]\displaystyle m=\frac{19-3}{4-2}=\frac{16}{2}=8[/tex]
