Answer:
5% of 13.5 is 0.675
Step-by-step explanation:
We need to determine 5% of 13.5 now and the procedure explaining it as suchStep 1: In the given case Output Value is 13.5.Step 2: Let us consider the unknown value as x.Step 3: Consider the output value of 13.5 = 100%.Step 4: In the Same way, x = 5%.Step 5: On dividing the pair of simple equations we got the equation as under13.5 = 100% (1).x = 5% (2).(13.5%)/(x%) = 100/5Step 6: Reciprocal of both the sides results in the following equationx%/13.5% = 5/100Step 7: Simplifying the above obtained equation further will tell what is 5% of 13.5x = 0.675%Therefore, 5% of 13.5 is 0.675
what is 16/27 reduced to
Answer:
This is the most simplified form of the fraction. As a percentage, 16/27 = 59.3% and as a decimal it is 0.593.
Step-by-step explanation:
Answer:
16/27
Step-by-step explanation:
Here we will simplify 16/27 to its simplest form and convert it to a mixed number if necessary.
In the fraction 16/27, 16 is the numerator and 27 is the denominator.
When you ask "What is 16/27 simplified?", we assume you want to know how to simplify the numerator and denominator to their smallest values, while still keeping the same value of the fraction.
We do this by first finding the greatest common factor of 16 and 27, which is 1.
Then, we divide both 16 and 27 by the greatest common factor to get the following simplified fraction:
16/27
Therefore, this equation is true:
16/27 = 16/27
If the numerator is greater than or equal to the denominator of a fraction, then it is called an improper fraction. In that case, you could convert it into a whole number or mixed number fraction.
16/27 = Proper Fraction
Which of the following are right triangle congruence theorems?
*Check all that apply.* (IMPORTANT)
A. Leg-leg(LL)
B. Hypotenuse-angle (HA)
C. Hypotenuse-leg (HL)
D. Leg-angle (LA)
[tex][Hello,BrainlyUser][/tex]
Answer:
A. Leg-leg (LL)
B Hypotenuse-angle (HA)
C Hypotenuse-leg (HL)
D. Leg-angle (LA)
Step-by-step explanation:
The HA theorem proves that if the hypotenuse and an acute angle of one right triangle are congruent to the hypotenuse and an acute angle of another right triangle, then the two triangles are congruent.
The HL theorem proves that any two right triangles that have a congruent hypotenuse and a corresponding, congruent leg are congruent triangles.
The LL theorem proves that any two right triangles that have a congruent hypotenuse and a corresponding, congruent leg are congruent triangles.
The LA theorem proves that if the leg and an acute angle of one right triangle are congruent to the corresponding leg and acute angle of another right triangle, then the triangles are congruent.
Thus, All of them are Correct.

The times of all 15 year olds who run a certain race are approximately normally distributed with a given mean Mu = 18 sec and standard deviation Sigma = 1. 2 sec. What percentage of the runners have times less than 14. 4 sec? 0. 15% 0. 30% 0. 60% 2. 50%.
The percentage of runners having times less than 14.4 sec is 0.15%. Then the correct option is A.
What is normal a distribution?It is also called the Gaussian Distribution. It is the most important continuous probability distribution. The curve looks like a bell, so it is also called a bell curve.
The times of all 15-year-olds who run a certain race are approximately normally distributed with a given mean (μ) = 18 sec and standard deviation (σ) = 1.2 sec.
The runners have times less than 14.4 sec.
The z-score is a numerical measurement used in statistics of the value's relationship to the mean of a group of values, measured in terms of standards from the mean.
[tex]\rm z-score = \dfrac{X - \mu}{\sigma }\\\\z-score = \dfrac{14.4- 18}{1.2}\\\\z-score = -3[/tex]
Then the Percentage will be

What effect did Geometry bring to the world/humans? Explain your answer in 3-5 sentences.
Answer:
Geometry has influenced how civilizations have constructed buildings and stadiums. In Ancient Greece, the “golden rectangle” was used to build aesthetically pleasing buildings that look to be in perfect proportion. It helps in the accurate calculation of the physical distances. It is employed in the field of astronomy to map the distances between stars & planets and between different planets. It also aids in the determination of a relationship between the movements of different bodies in the celestial environment.

An outlier is a number that is much larger or smaller than the general populous of numbers. For example, if there was a dot plot with dots clustered at 2, 3, and 5, but there was one or two dots around 10, then 10 would be considered an outlier.Let's put the numbers in order to see easier which numbers are outliers. I will not copy down repeating numbers.0, 1, 2, 3, 4, 5, 6, 10, 11.10 and 11 are isolated.If I am incorrect in my reasoning, please let me know so that I can plan better for my future answers.

Answer:
Let 6 men (M1) working 8 hours (D1) earn $8400 (W1).
∴ 9 men (M2) working six hours (D2) earns:
M1 × D1/W1 = M2 × D2/W2
W2 = 8400 × 9 × 6/6 × 8

Step-by-step explanation:
geometric sequence means that every term is created by multiplying the previous term by a constant factor.
we can see the constant factor directly, I am sure, but let's do it formally correct :
-1/8 × f = -1/4
f = -1/4 / -1/8 = -1/4 × -8/1 = -8/-4 = 2
so, yes, every new term of the sequence is created by multiplying the previous term by 2.
a0 = -1/8
a1 = a0 × 2 = -1/8 × 2 = -2/8 = -1/4
a2 = a1 × 2 = a0 × 2×2 = -1/8 × 2×2 = -1/8 × 4 = -4/8 = -1/2
...
an = a0 × 2^n = -1/8 × 2^n
a6 = -1/8 × 2⁶ = -1/8 × 64 = -8
so, the only questing is, where does your teacher start the count for such a geometric sequence ?
do you call the first term a0 or a1 ?
my solution above starts with a0.
but if it should start with a1, then we need to reduce the exponents of 2 by 1 :
an = -1/8 × 2^(n-1)
and a6 would be
a6 = -1/8 × 2⁵ = -1/8 × 32 = -4

D
Answer:
cos F is 15/28
Step-by-step explanation:
Use SOH CAH TOA
CAH is for cosine and it's Adjacent over Hypotenuse
the adjacent side of F is 15 and the hypotenuse is 28
So 15/28 which does not simplify
