Answer:
Q1 b = 105 c= 75 D=105
Step-by-step explanation:
A aNd C are the same and B and D are the same as they are opposite angles. So , 75 +75 = 150 . Then , 360 - 150 = 210 . 210÷ 2 = 105
Hence,
A= 75 B = 105 C=75 D = 105

The mean height of an adult giraffe is 17 feet. Suppose that the distribution is normally distributed with standard deviation 0.9 feet. Let X be the height of a randomly selected adult giraffe. Round all answers to 4 decimal places where possible.
c. What is the Z-score for a giraffe that is 18.5 foot tall?
d. What is the probability that a randomly selected giraffe will be shorter than 17.5 feet tall?
e. What is the probability that a randomly selected giraffe will be between 16.7 and 17.2 feet tall?
f. The 70th percentile for the height of giraffes is ___ ft.
Answers
Answer:
Median =17
Step-by-step explanation:
Given that the mean height of an adult giraffe is 17 feet. Suppose that the distribution is normally distributed with standard deviation 0.9 feet. Let X be the height of a randomly selected adult giraffe. X is a random variable.
a) X is N(17, 0.9)
b) Median giraffe height = 17 ft since in normal distribution mean = median
c) When x = 18.5, Z = 18.5-17/0.9 = Z= 0.1667
d) P( x < 18) = P( Z < 56)
= 0. 2877
e) P(16.9 < x < 17.9) = P(-0.11 < z < 1) = .0.438 + 0.3413
= 0.3851
f) 75th percentile for z is 0.675
x = 17.9 + 0.9 (0.675)
= 18.5075

Step-by-step explanation:
The object is at h = 0 when it land so
-5x^2 + 20x + 60 = 0
-5(x^2 - 4x) = -60
-5[(x - 2)^2 - 4] = -60
(x - 2)^2 - 4 = -60/-5 = 12
(x - 2)^2 = 16.
Solving the above:
Take the square root of both sides:
x - 2 = 4
x = 2 + 4
x = 6 seconds

Find the area of the triangle below.
Carry your intermediate computations to at least four decimal places. Round your answer to the nearest hundredth
Answers
Answer:
20
Step-by-step explanation:
Since this is not a right angle, we can use the formula [tex]Area= Sin(y) (\frac{1}{2}ab)[/tex]
a=7
b=10
y=35
So, when we plug these values in, we get:
[tex]a=Sin(35)(\frac{(10)(7)}{2})\\\\=35sin(35)\\=20.075\\[/tex]
rounded to the nearest hundredth, I believe it's 20.

Answer:
The answer can be literally anything.
Step-by-step explanation:
The answer can be literally anything. I can see most of the answers says 3 but, that is only one of the solutions. It is the answer when questions defines the relationship as number of characters, but the question never says that. All it says is, find me a relation which satisfies few values, and then find the relationship value at a new point.
Let us start by examining the question. So here is the question in mathematical terms:
Given:
f(1)=3, f(2)=3, f(3)=5, f(4)=4 and f(5)=4
Find f(6).
So if we assume the function to be f(x) then we know its value at 5 points.
Let’s say f(6)=K, so now we know it’s value at 6 points.
Now, given the value of a function at N points, we can always find a (N-1) degree polynomial which will be that function.
Now, you can put whatever value of K you want, and you will get corresponding set of coefficient vector which will satisfy the function values at the given points.
On a side note, I don’t consider this puzzle a good puzzle, since most of the people asking it expect only 3 as answer. They basically want you to limit the way you think, in a particular direction, which I think is not a very great idea.

It concludes that 6 = 3 for the given pattern, because in "six" has "3" letters.
What is the pattern in the reasoning?A pattern is a recurring series of occurrences or elements that can be used to identify and categorize various forms of data or information.
As per the question,
1=3
2=3
3=5
4=4
5=4
If we write "1" in a word then we will write "one" and if we count the letter it will give us "3".
If we write "2" in a word then we will write "two" and if we count the letter it will give us "3".
If we write "3" in a word then we will write "three" and if we count the letter it will give us "5".
Similarly, if we write "6" in a word then we will write "six" and if we count the letter it will give us "3".
Hence, 6 = 3.

Answers
Answer:
point = (-3, 5)
slope = 3/4
Step-by-step explanation:
The formula for point slope is:
y - y1 = m (x - x1)
point (x1, y1)
slope m
So with your equation:
y - 5 = 3/4 (x+ 3)
point = (-3, 5)
slope = 3/4
Answer: M=0,75

We have a linear function y=mx+bwhere m is slope ; by intercept Let's bring the functions to the standard form[tex]\displaystyle y-5 =\frac{3}{4} \cdot (x+3) \\\\ y=\frac{3x+9}{4} +5 \\\\ y=0,75x+2,25+5 \\\\ y=0,75x+7,25 \\\\ y=\boldsymbol {0,75}x+7,25 \\\\ \rm Then : \\\\ M=0,75[/tex]
