Answer:
7- 780 m
8- 9,459 cm
9- 864 cm
10- 151 in
Step-by-step explanation:
7- The volume of a rectangular pyramid is:
V=(l x w x h) / 3We just have to substitute the values:
V= 13×12×15 / 3V= 780 m8- The volume of a cone is:
V=hπr² / 3Let's substitute the values and solve:
24×π×19.4² / 39,458.9If you want to round it, the answer will be:
9,459 cm9- The volume of a square pyramid V = a²h / 3, where a is the base and h the height.
So,
V= 12²×18 / 3864 cm10- The volume of the cone is V = hπr² / 3
Then,
V= 16×9×π / 39 is the diameter, which is the radius two times. As you see, what the formula asks is for the radius at the second power -multiplied by itself two times-, but if we get the diameter value instead, there is no need to multiply it. The diameter stays the same.
V= 150.7If you want to round it to the nearest tenth, the answer is:
151 in.Hope this helps!!

A Biology teacher wants to see if there is any difference in the abilities of students enrolled in biology today and those enrolled five years ago. A sample of final examination scores from students enrolled today and from students enrolled five years ago was taken. You are given the following information. Today Five Years Ago 81 85 σ 14.5 8.5 n 81 36 The point estimate for the difference between the means of the two populations is
Answer:
The point estimate for the difference between the means of the two populations is x1`-x2`= 81-85=-4 where x1` is the mean of the of the first population and x2` is the mean of the second population.
Step-by-step explanation:
The data given is
Today Five Years Ago
X` 81 85
σ 14.5 8.5
n 81 36
The point estimate for the difference between the means of the two populations is x1`-x2`= 81-85=-4 where x1` is the mean of the of the first population and x2` is the mean of the second population.
The test statistics that will be used is
Z= x1-x2/ √σ₁²/ n₁ + σ₂²/n₂
Z= 81- 85/ √14.5² /81 + 8.5² /36
z= -4/√210.25/81+ 72.25/36
z= -4/2.1454
z= -1.8644

to spend to much traveling and country the day she arrived the exchange rate was 1.4 country a dollars Per country B dollars if she exchange 500 country B dollars when she arrived how many country eight dollars she receive
Answer:
She receives 700 country A dollars.
Step-by-step explanation:
This question is solved by proportions, using a rule of three.
1.4 country a dollars Per country B dollar
She exchanges 500 country B dollars, so:
1.4 country A dollars - 1 country B dollar
x country A dollars - 500 country B dollars
Applying cross multiplication:
[tex]x = 1.4*500 = 700[/tex]
She receives 700 country A dollars.

9. Multiply the money he has by the portion he spent:
75 x 3/5 = (75 x3)/5 = 225/5 = 45
He spent $45
10. First rewrite 4 1/8 as an improper fraction
33/8
Now multiply by 1/3:
33/8 x 1/3 = (33 x1) /(8 x 3) = 33/24 = 1 3/8

Determine whether the underlined numerical value is a parameter or a statistic. Explain your reasoning. for a certain movie 64.3% of the 112 members of the audience were females
Answer:
The given numerical value is a Parameter.
Step-by-step explanation:
Given - For a certain movie 64.3% of the 112 members of the audience were females.
To find - Determine whether the underlined numerical value is a parameter or a statistic.
Proof -
Given that, 64.3% of the 112 members of the audience were females.
Now,
64.3% of 112 = [tex]\frac{64.3}{100}*112[/tex] = 72.016
Since it is not a perfect number
And Human can not be in fraction
So,
The given numerical value is a Parameter.

solve the following equation 1÷x=2
Answer:
Your answer would be x = 1/2
Step-by-step explanation:
1/x = 2
You would divide x on both sides...then they would cancel each other out.
But now you're left with...
1 = x•2
So, re-order the terms so constants are on the left
1 = 2x
Divide 2 on both sides...
Now you're left with
1/2=x or more practically it would be x = 1/2
Hope this helps!

Which expression is equivalent to (see the picture)
A. 20x-21y +14
B. 20x + 11y + 14
C. 20x - 11y + 6
D. 20x + 21y +6
Answer:
A
Step-by-step explanation:
[tex]\frac{1}{5} (150x-80y+50-50x-25y+20)[/tex]
step 1 apply the 1/5 to everything that inside of the parenthesis
[tex]\frac{150x}{5} =30x\\\\\frac{-80y}{5} =-16y\\\\\frac{50}{5} =10\\\\\frac{-50x}{5} =-10x\\\\\frac{-25y}{5} =-5y\\\\\frac{20}{5} =4[/tex]
we now have 30x - 16y + 10 - 10x - 5y + 4
Step 2 combine like terms
30x - 10x = 20x
-16y - 5y = - 21y
10 + 4 = 14
we're left with 20x - 21y + 14 Which corresponds with answer choice A
Answer:
20x-21y+14
Step-by-step explanation:
1/5(150x-80y+50-50x-25y+20) is equal to 1/5(150x) + 1/5(-80y) + 1/5(50) + 1/5 (-50x) + 1/5(-25y) + 1/5(20)
So if we simplify, we would have 30x + (-16y) + 10 + (-10x) + (-5y) + 4, or 30x -16y + 10 -10x -5y + 4
When organizing the values by variable, the equation would look like this -
30x - 10x -16y -5y + 10 + 4
Combining like terms will result in 20x -21y + 14.
Hope this helps!

Find the solution of the following equation whose argument is strictly between 90° and 180°.
Answer:
180degreesStep-by-step explanation:
Given the complex value
z² = -81i
z = (-81i)^1/2
Get the argument of -81i
theta = arctan(y/x)
theta = arctan(-81/0)
theta = -90degrees
theta = -π/2
Since tan is negative in the secind quadrant
theta = π - π/2
theta = π/2
According to demoivres theorem
theta = 1/2 * π/2
theta = π
theta = 180degrees
