Answer: The largest marginal relative frequency is 0.90 and it represents the probability of an individual having brown hair given that they have brown eyes.
Step-by-step explanation:
The reason why 0.90 represents the probability of an individual having brown hair given that they have brown eyes is because the study shows that 90% of the people who have brown eyes also have brown hair. This is a conditional probability, which means that it is the probability of one event happening given that another event has already happened. In this case, the event of having brown hair is conditional on the event of having brown eyes. The probability of 0.90 is calculated by taking the total number of individuals with brown eyes and brown hair and dividing it by the total number of individuals with brown eyes. The number is large because 90% of the individuals with brown eyes have brown hair, it is the largest because it is the highest probability among the other marginal relative frequencies. This indicates that the majority of people with brown eyes also have brown hair

What trigonometry is, explained?Trigonometry is a branch of mathematics that studies how square side length The field's initial development took place during the Baroque era, more likely and around third century BC, as a result of the merger of astronomer and geometry studies. Numerous geometric equations and their potential applications to calculations are covered by precise mathematical approaches. Mathematics has six fundamental operations. They are known by a variety of names and abbreviations, including sine, quadrature, parallel, secant, etc (csc). The study of mathematics is focused mostly on the characteristics of right triangles. The ability to understand geometry, however, necessitates familiarity with each polygon's properties.
Here,
Given : Provided: tan = (-5/3)

what is the solution of √2x+4 - √x = 2
please show with work done!
Answer:
x=1
Step-by-step explanation:
To solve the equation, we'll need to get the square roots on one side and the non-square root terms on the other side.
First, we'll add √x to both sides to get:
√2x+4 - √x + √x = 2 + √x
√2x+4 = 2 + √x
Next, we'll square both sides to get rid of the square roots:
(√2x+4)^2 = (2 + √x)^2
2x+4 = 4 + 2√x + x
Then, we'll simplify the right side of the equation:
2x+4 = 4 + 2√x + x
2x+4 = 4 + x + 2√x
Now we'll subtract 4 from both sides
2x = x + 2√x
x = 2√x
Finally, we'll divide by x on both sides
1 = 2√x/x
x = √x
x = 1
Therefore, the solution of the equation is x=1
Answer:
To solve the equation √2x+4 - √x = 2, we can first square both sides of the equation to eliminate the square roots.
Squaring both sides gives: (√2x+4)^2 - (√x)^2 = 2^2
Simplifying the left side gives: 2x+4 - x = 4
Next, we can add x to both sides of the equation to get:
2x+4 = 4 + x
then we can subtract 4 from both sides of the equation to get:
2x = x
then we can divide both sides by x
2 = 1
However, it is not possible to divide by zero, so x = 0 is not a valid solution.
This equation is an extraneous solution because the assumption that x is not equal to 0 led to a valid solution, but when x = 0, the equation is not defined.
Therefore, the solution of √2x+4 - √x = 2 is x = any value except 0.
16^x^2=8^0
16 to the power of x to the power of 2 equals 8 to the power of 0
The exponent x in the equation must be equal to 0.
How to solve the given equation?Here we have the following equation:
16^x^2=8^0
First, notice that any number to the power of zero (except for the number 0) is equal to 1.
a^0 = 1
16^x^2=8^0
16^x^2 = 1
Now, trivially, if we use x = 0 we will get:
c
Particularly, 0^2 = 0
So we can rewrite:
16^0^2 = 1
16^0 = 1
1 = 1
So the solution is x = 1.

A nine-month old baby drank an average of 7 1/4 oz during each of four feedings. If the baby drank 7 1/2oz, 7 3/8oz, & 6 3/8oz in the first three feedings, how many ounces were taken during the fourth feeding?
A) 7 3/8
B) 6 3/8
C) 6 3/4
D) 7 3/4
Show work please
Answer: D) 7 3/4
Step-by-step explanation:
With averages, we add all the values and divide by the number of values. Here, we know three out of the four days, let's label the day we don't know x. There are four days, so we can divide by four. 7 1/4 is the average, so we can set the equation equal to 7 1/4.
7 1/4 = (7 1/2 + 7 3/8 + 6 3/8 + x) / 4
Let's multiply both sides by 4 to get rid of the fraction. Let's also add what is in the parentheses
29 = 21 1/4 + x
Now we can isolate x by subtracting 29-21 1/4
so
x = 7 3/4 thus the answer is D
Answer:
D) 7 3/4
Step-by-step explanation:
Let x = amount of last feeding.
7 1/4 = (7 1/2 + 7 3/8 + 6 3/8 + x)/4
4 × 7 1/4 = 7 1/2 + 7 3/8 + 6 3/8 + x
28 + 1 = 7 4/8 + 7 3/8 + 6 3/8 + x
29 = 20 10/8 + x
(20 10/8 is the same as 20 + 10/8 = 20 + 8/8 + 2/8 = 20 + 1 + 1/4 = 21 + 1/4 = 21 1/4)
29 = 21 2/8 + x
29 = 21 1/4 + x
x = 29 - 21 1/4
x = 28 4/4 - 21 1/4
x = 7 3/4

a) Show that the two shorter sides in triangle A have the
same length as the two shorter sides in triangle B.
Using pythagoras theorem formula, c² = a² +b² We can see that the two shorter sides have the same length which is 5cm
Since all the sides of the triangle are the same, hence the two triangles are congruent.
What is Pythagoras' theorem ?
Pythagoras' theorem is the square of the hypotenuse in a right-angled triangle is equal to the sum of the squares of the other two sides.
The two shorter sides have the same length which is 5cm
Since all the sides of the triangle are the same, hence the two triangles are congruent.
Let the sides of the triangles be a, b and c. According to Pythagoras theorem;
c² = a² +b²
where:
a is the hypotenuse (longest side)
For triangle A:
c = 13
b = 12
Get "a"
13² = 12² +b²
b² = 25
=> b = 5 cm
Similarly for triangle B:
c² = 5² +12² = 169
=> c=13 cm
We can see that the two shorter sides have the same length which is 5cm
Since all the sides of the triangle are the same, hence the two triangles are congruent.
