Answer:
Option (1)
Step-by-step explanation:
Radius of the spherical structure = 37.5 feet
Surface area of each panel = 49 square feet
Sphere is covered with panels.
Therefore, area of the panels needed = [tex]\frac{\text{Total surface area of the sphere}}{\text{Area of one panel}}[/tex]
Surface area of the sphere = 4πr²
Here 'r' = radius of the sphere
For a sphere having radius 'r' = 37.5 feet,
Surface area of the sphere = 4π(37.5)²
= 17671.5 feet²
Number of panels required to cover the sphere = [tex]\frac{17671.5}{49}[/tex]
= 360
Therefore, Option (1) will be the answer.
Answer:
360

Algebra I
TermsStep-by-step explanation:
Step 1: Define Equation
10x - 6 + 2x = 4(3x - 1) - 2
Step 2: Solve for x
Combine like terms: 12x - 6 = 4(3x - 1) - 2Distribute 4: 12x - 6 = 12x - 4 - 2Combine like terms: 12x - 6 = 12x - 6Add 6 on both sides: 12x = 12xDivide 12 on both sides; x = xHere we see that x does indeed equal x.
∴ any value x would work as a solution to the equation, hence we have infinite amount of solutions.
Answer:
The answer is infinite.
Step-by-step explanation:
So if you first simplify the problem you would have:
12x - 6 = 4 ( 3x - 1 ) - 2
I just combined like terms.
Then you distribute the 4 to the 3x and the negative 1.
So you would have 12x - 6 = 12x - 4 - 2
So once again you would combine like terms and get 12x - 6 = 12x - 6
If you simplified it out and subtracted like terms from both sides you would get 0 = 0 which is true so there is infinite solutions.

Jamie is an analyst at an education technology company. She gathered data on the results of a certain type of question. Of the 2,000 responses she looked at, 1,092 responded correctly. What equation could Jamie use to calculate the margin of error at a 90% confidence interval?
Answer:
1st Square - 1.65
2nd Square - 0.546
3rd Square - 0.546
4th Square - 2000
(got it right on edmentum)
for better understanding of what I mean please take your time to look at the picture below↓Step-by-step explanation:
The margin of error for the 90% confidence interval with a probability of success of 0.546 is 0.0183.
What is the margin of error?The probability or the chances of error while choosing or calculating a sample in a survey is called the margin of error.
Jamie is an analyst at an education technology company. She gathered data on the results of a certain type of question. Of the 2,000 responses she looked at, 1,092 responded correctly.
Then the value of p will be
[tex]\rm p = \dfrac{1092}{2000}\\\\p = 0.546[/tex]
And the z-value for the 90% confidence interval will be
[tex]\rm z = 1.645[/tex]
And N = 2000
Then the margin of error (ME) will be
[tex]ME = z \times \sqrt{\dfrac{p(1-p)}{N}}\\\\ME = 1.645\times \sqrt{\dfrac{0.546(1-0.546)}{2000}}\\\\ME = 0.0183[/tex]

Celso's house is on the market for $220,000. Last year is was on the market for $240,000 but didn't sell. What is the percent decrease in the price of his house
Answer:
91.66666666666667
Step-by-step explanation:
240,000/100 = 220,000/x
220,000 x 100 = 22,000,000
22,000,000 divided by 240,000 = 91.66666666666667
Answer:
This type of problem requires you to calculate the Percentage decrease
Step-by-step explanation:
Formula: Percentage Decrease=
Starting Value minus Final Value / Starting Value x 100
240,000 - 220,000 = 20,000
so 20,000/240,000 = 0.0833333333
so 0.0833333333 x 100 =8.33333333%
ans. 8.33333333% decrease in the price of the house.
jeremiah makes 4/5 of the free throw shots he attempts in basketball. Jeremiah likes to shoot free throws until he misses one. Let F be the number of shots it takes Jeremiah to miss his first free throw. Assume that the results of each shot are independent.
Answer:
Mean - 5
Standard Deviation - 4.5
Step-by-step explanation:
Just got it correct on Khan Academy :)
80% is her free throw shooting percentage.
What is Fraction?A fraction represents a part of a whole.
We can construct a fraction in which the numerator is how many shots she makes, and the denominator is how many shots she took overall.
We now have the following fraction:4/5
To convert this to a percentage, we want the denominator to be 20/20
4/5×20/20
80/100
0.8
Now multiply 0.8 with 100
0.8×100=80
Hence, 80% is her free throw shooting percentage.

Answer:
$37623.04
Step-by-step explanation:
The formula we'll use for this is the simple interest formula, or:
[tex]I=p*r*t[/tex]
Where:
P is the principal amount, $1088.00.
r is the interest rate, 839.5% per year, or in decimal form, 839.5/100=8.395.
t is the time involved, 4....year(s) time periods.
So, t is 4....year time periods.
To find the simple interest, we multiply 1088 × 8.395 × 4 to get that:
The interest is: $36535.04
Usually now, the interest is added onto the principal to figure some new amount after 4 year(s),
or 1088.00 + 36535.04 = 37623.04.

What is the classification of the triangle by its angles and by its sides?
Answer:
Step-by-step explanation:Triangles can be classified by their sides and by their angles. When classifying a triangle by its sides, you should look to see if any of the sides are the same length. If no sides are the same length, then it is a scalene triangle. If two sides are the same length, then it is an isosceles triangle.

Step-by-step explanation:
Given
[tex]T_1 =0^{\circ}[/tex]
[tex]T_2 =-12\frac{1}{4}^{\circ}[/tex]
[tex]Time = 3\frac{1}{2}\ hr[/tex]
Required
Determine the change in temperature per hour
This is calculated as:
[tex]Rate = \frac{T_2 - T_1}{Time}[/tex]
[tex]Rate = \frac{-12\frac{1}{4}^{\circ} - 0^{\circ}}{3\frac{1}{2}\ hr}[/tex]
[tex]Rate = \frac{-12\frac{1}{4}^{\circ} }{3\frac{1}{2}\ hr}[/tex]
Convert to improper fractions
[tex]Rate = \frac{-\frac{49}{4}^{\circ} }{\frac{7}{2}\ hr}[/tex]
Express as:
[tex]Rate = -\frac{49}{4}^{\circ} /\frac{7}{2}\ hr[/tex]
