What is Pythagoras theorem?
The Pythagoras theorem states that in a right triangle, the square of the hypotenuse is equal to the sum of the square of the other two sides.
Given that;
In triangle ADC,
AC = 9
AD = 16
Hence, We have;
Line l is divide the base AC in two equal parts.
Hence,
⇒ AB = AC
This gives,
AB = 9 units.

In one region, the September energy consumption levels for single-family homes are normally distributed with a mean of 1050 kWh and a standard deviation of 218 kWh. For a randomly selected home, find the probability that the September energy consumption level is between 1100 kWh and 1225 kWh.
a. 0.1971
b. 0.3791
c. 0.2881
d. 0.0910
e. 0.8029
Answer:
a. 0.1971
Step-by-step explanation:
Z score is used to measure by how many standard deviations the raw score is above or below the mean. It is given by the formula:
[tex]z=\frac{x-\mu}{\sigma}\\ \\Where\ \mu=mean, x=raw\ score, \sigma=standard\ deviation[/tex]
Given that:
μ = 1050 kWh, σ = 218 kWh
For x = 1100 kWh
[tex]z=\frac{x-\mu}{\sigma}=\frac{1100-1050}{218} =0.23[/tex]
For x = 1225 kWh
[tex]z=\frac{x-\mu}{\sigma}=\frac{1225-1050}{218} =0.80[/tex]
From the normal distribution table, P(1100 < x < 1225) = P(0.23 < z < 0.8) = P(z < 0.8) - P(z < 0.23) = 0.7881 - 0.5910 = 0.1971

Answer:
The final price is $33.80.You saved $18.20.
Step-by-step explanation:
Answer:
The original price was $80.
Step-by-step explanation:
The original price is x.
x is the full original price, so it is 100% of the original price.
The sale is 35%, so we subtract 35% from 100%.
100% - 35% = 65%
Since the discount was 35%, then the sale price is only 65% of the original price.
65% of the original price is $52
65% * x = 52
0.65x = 52
x = 52/0.65
x = 80
Answer: The original price was $80.

Loop
Answer: 3 × 10⁴ miles²
Step-by-step explanation:
Given that:
Estimated Surface area of Lake = 30,000 square miles
Expressing the estimated area as a whole number multiplied by a power of ten
Hence, we are required to express the surface area in standard form:
30,000 miles ² in standard format:
30,000 is equivalent to (3 × 10,000)
3 is a whole number
10,000 = (10 * 10 * 10 * 10)= 4 th power of 10
10,000 = (10 * 10 * 10 * 10) = 10⁴
Hence,
3 × (10 * 10 * 10 * 10) = 3 × 10⁴ miles²

What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be represented as A
Now , the value of A is
f ( x ) = 2,708.92(1.12) - 12
On simplifying the equation , we get
To find the initial amount , substitute x = 0
when x = 0
Substitute the value of x in equation , we get
f ( 0 ) = 2708.92 ( 0 ) - 12
f ( 0 ) = -12
Therefore , the initial amount is -12
Hence , the value of the equation f ( 0 ) ≠ 2,708.92

Steven Starr has an idea for a desert he is preparing to sell via food truck for restaurant week- grilled bananas with Belgian chocolate ganache. The bananas go through a 4-step process consisting of pealing, filling, grilling, and the last 2 steps are performed simultaneously- splashing and wrapping. Pealing takes 1 minute, filling takes 2 minutes and grilling takes 5 minutes. Splashing takes 3 minute and wrapping takes 3 minutes. a. The bottleneck of the process is _____, with an hourly capacity of _____.
Answer:
a) grilling
b) 12 grilling process per hour
Step-by-step explanation:
the bottleneck in this process is grilling, which slows down production by taking a considerable amount of time.
Grilling takes 5 minutes, which is the longest of any other stage of process
In one hour there are 60 minutes
The hourly rate of grilling is therefore 60/5 = 12 grilling process per hour

Felipe made sand art bottles to sell at his school's craft fair. He wanted to use 9 different colors of sand. So, he bought 1 pound of each color. Then, he filled as many 6-ounce bottles as he could. How many sand art bottles did Felipe make?
Answer: Felipe made 24 sand art bottles.
Step-by-step explanation:
Given: Total different colors of sand = 9
Weight of each color sand = 1 pound
Then, the weight of all 9 colors would be 9 × 1 = 9 pounds
Since 1 pound = 16 ounces
Then, 9 pounds = 9 × 16 = 144 ounces
capacity of each bottle = 6 ounce
Then, the number of bottles required = ( 144 ounces) ÷ 6
= 24
Hence, Felipe made 24 sand art bottles.
Answer:

Answer:
3. Standard deviation is the square root of the variance.
4. Standard deviation is useful because it has the same units as the underlying data.
Step-by-step explanation:
3. In statistics, the dispersion in a given data with respect to its mean distribution can be determined or measured by standard deviation and variance. The standard deviation of a distribution can also be determined as the square root of variance.
4. Standard deviation is measured in the same units as that of the original data. Thus it has the same units as the underlying data.

What is the inverse of f(x) = 1/3 x +2
Answer:
The inverse of this function is f(x) = 3x - 6.
You can find the inverse of any function by switching the f(x) and x values. Once you've done that, solve for the new f(x). The result will be the inverse function. The step-by-step process is below.
f(x) = 1/3x + 2 ---> Switch f(x) and x values
x = 1/3f(x) + 2 ---> Subtract 2 from both sides
x - 2 = 1/3f(x) ----> Multiply both sides by 3
3(x - 2) = f(x) ----> Distribute the 3
3x - 6 = f(x) ----> Place in the proper order for formatting purposes
f(x) = 3x - 6
And that is your inverse function.
