Answer:Extract the formula for the height of a rectangular-based pyramid using your knowledge of algebra. H = V / (L x W) / 3. For instance, V = 60 cubic cm, L = 4 cm and W = 6 cm.
Step-by-step explanation:
Find the interquartile range of the data.
84,75,90,87,99,91,85,88,76,92,94
IQR is shorthand for interquartile range
=========================================================
Explanation:
The original list is {84,75,90,87,99,91,85,88,76,92,94}
It sorts to {75,76,84,85,87,88,90,91,92,94,99}
Pick out the middle most value, which is 88 in slot 6. A quick way to get here is to see that there are n = 11 values in this set. So n/2 = 11/2 = 5.5 which rounds to 6, and that tells us the slot number where the median is held. If n is an even number, then you'll need to use the midpoint formula for the two middle-most items.
After we determine the median is 88, we split the sorted data set as follows:
L = {75,76,84,85,87}
U = {90,91,92,94,99}
Everything in set L is below the median. L for lower.
Everything in set U is above the median. U for upper.
Sets L and U have 5 items each. Note that 5+1+5 = 11 = n.
-------------
The median of set L is 84, so Q1 = 84
The median of set U is 92, so Q3 = 92
Q1 and Q3 are the first and third quartiles respectively. Subtracting them gets us the IQR (interquartile range)
IQR = Q3 - Q1
IQR = 92 - 84
IQR = 8
The IQR helps give us a sense how spread out the data set is. It's similar to the range, which is found by range = max - min. The larger the (interquartile)range, the more spread out the data set will be.

Answer:
89*
Step-by-step explanation:
To find the value of m<1, you need to find the angle right next to it (the third interior angle that isn't labeled).
To find that angle (let's call it x), we have to use an equation.
Since a triangle has a sum of 180* for the interior angles in it, then we can use that to solve for x.
x + 53 + 36 = 180
x + 89 = 180
x = 91
Now to find m<1, we need to use the supplementary angles theorem.
Since m<1 and x are supplementary angles, the sum of those angles would be 180. Using this, we can create an equation.
x + m<1 = 180
91 + m<1 = 180
m<1 = 89
Hence, m<1 is 89*!

Gió thổi trên mặt nước trong các đại dương chịu trách nhiệm cho dòng hải lưu. Tuy nhiên, dòng hải lưu trong đại dương không được hình thành bởi gió đơn thuần. Nước gần cực lạnh trong khi nước gần xích đạo ấm. Sự chênh lệch nhiệt độ giữa hai vùng nước này cũng chịu trách nhiệm cho sự hình thành dòng hải lưu. Địa hình đáy đại dương, mưa và thậm chí thủy triều cũng gây ra dòng chảy trong nước.

Use the trig ratio tan to find b
4.5 x tan (23) = b = 7.14668887526
7.1
Answer:
b ≈ 1.9
Step-by-step explanation:
Using the tangent ratio in the right triangle
tan23° = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{b}{4.5}[/tex] ( multiply both sides by 4.5 )
4.5 × tan23° = b , then
b ≈ 1.9 ( to the nearest tenth )

The hardest part about negative numbers in addition is remembering when to add, rather than subtract. In the last equation, we add the numbers together, because the negative sign cancels out with subtraction. All of the other equations we can follow exactly what it says to do, because there are no minus signs right next to each other.

Answer:
From least to greatest
C

A
Step-by-step explanation:
Function A is the only one with a positive y-intercept
so it's the greatest
Function B has a y-intercept of -1 as read of the graph
it is the middle one
Function C has a y-intercept of -9/4 as given in point (0, -9/4)
this is the least

Find the sum of the first 41 terms of the following series, to the nearest integer. 4, 12,20,...
Answer:
Sum of the first 41 terms = 6724
Step-by-step explanation:
[tex]a_{41} = a_1 + (n - 1 )d = 4 + (41 - 1) \times 8= 4 + 40 \times 8 = 324\\\\S_n = \frac{n}{2}(a_1 + a_n)\\\\s_{41} = \frac{41}{2} (4 + 324) = \frac{41}{2} \times 328 = 41 \times 164 = 6724[/tex]
The sum of the first 41 terms of the following series, to the nearest integer, is 6724.
What is an arithmetic sequence?A series of integers called an arithmetic progression or arithmetic sequence (AP) has a constant difference between the terms.
Given:
An arithmetic sequence,
4, 12,20,...
The common difference d,
d = 20 - 12 = 8.
To find the sum of the first 41 terms:
We will find the 41st term.
Remember that,
aₙ= a₁ + (n-1)d
a₄₁ = 4 + (40)8
= 324
The sum of the first 41 terms,
Sₙ = (41/2)(4 + 324) = 6724.
Therefore, the sum is 6724.

WILL GIVE BRAINLIEST: What is the local minimum value of the function g(x)=x^4-5x^2+4? (Round answer to the nearest hundredth)
Answer:
Step-by-step explanation:
you can find where the first derivative is 0 to find the critical points
g'(x) = ( x^4 -5x^2 +4)' = 4x³-10x
g'(x) =0, make y =0 to find find where g'(x) is 0
4x³-10x =0 , factor 2x
2x(2x²-5)= 0 , each factor must be 0
2x= 0, so x= 0
2x²-5 =0, so x = ±√5/2
we now have 3 critical points -√5/2, 0, and √5/2
make intervals (-∞, -√5/2), (-√5/2, 0) , (0, √5/2) and (√5/2, +∞)
pick a point to test on each interval: -2, -1, 1 and 2 for example, and
calculate g'(x) = 4x³-10x at those points
for x= -2 we have 4(-2)³-10(-2) = -12 , negative number, decrease
for x= -1 we have 4(-1)³-10(-1) =6, positive number, increase
for x= 1 we have 4(1)³-10(1) = -6, negative number, decrease
for x= 2 we have 4(2)³-10(2) = 12, positive number, increase
we went from a decrease to an increase on intervals (-∞, -√5/2), (-√5/2, 0) so x= - √5/2 ≈ -1.58 is a minimum
we went from a decrease to an increase on intervals (0, √5/2), (√5/2, +∞) so
x= √5/2 ≈ 1.58 is a minimum as well

Jack is 5 years older than Mary. In four years the sum of their age is 33 years old. What are their ages?
Answer:
mary=10 jack=15
Step-by-step explanation:
After 4 years Mary (x+4), Jack's age (x+5) + 4.
sum of the ages after 4 years :(x+4) + (x+5) +4=33
Simplifying the equation:
2x+13 = 33 ----->> 2x=20----->>>>x = 10 Mary's age
10 + 5 = 15 which is Jack's age.
