help me how to answer this please

Step-by-step explanation:
x^2 + 4x - 21 = 0
(x - 3)(x + 7) = 0
x = 3 or x = -7
x^2 - 14x = -24
x^2 - 14x + 24 = 0
(x - 12)(x - 2) = 0
x - 12 = 0 or x - 2 = 0
x = 12 or x = 2
2x^2 - 12 = 2x
x^2 - x - 6 = 0
(x - 3)(x + 2) = 0
x = 3 or x = -2

Which of the following quantities are continuous ?
Answers
Answer: A. only II
Step-by-step explanation:
Mathematics calculus differentiates things into discrete and continuous. Discrete things have indivisible units, the example will be how many dogs in a village. There is no half dog, it's either one, two, etc. But the distance covered by train can be written as half miles, it's the divisible unit.
The number of books and bracelets also discrete, thus the answer is A.

inside each set and subsets .write at least 5 example of each kind of number. integers , whole ,rational ,natural ,irrational
Answers
Answer:
Integers: is the set of all the numbers that can be created by adding ones or subtracting ones a given number of times to zero.
for example:
4 = 0 + 1 + 1+ 1 +1 is an integer.
-3 = 0 - 1 - 1- 1 is an integer.
0 is also an integer, you add ones zero times.
Then 5 examples of integers can be:
-10, -5, 0, 4, 18
Whole numbers: this set is the set of the positive integers and the zero.
Then 5 examples are:
0, 1, 4, 6, 173
Rational: All the numbers that can be written as a quotient of two integers.
5 examples are:
2/2, 7/3, 4/16, 100/10, -500/1048
Natural: Is the set of the positive integers.
5 examples are:
1, 4, 6, 120, 47
Irrational: Are numbers that have infinite digits after the decimal point, such that there is no pattern in those digits. The squareroots of prime numbers are always irrational numbers.
5 examples are:
pi, √2, √3, √5, √13
where pi = 3.141592653...

Suppose that 84% of the cases of car burglar alarms that go off are false. Let p be the proportion of false alarms in a random sample of 110 cases of car burglar alarms that go off. Calculate the mean and standard deviation of p and describe the shape of its sampling distribution.
Round your answer to four decimals places if necessary
up= ______
op= ______
The sampling distribution of p is normal or skewed to the right?
Answers
Answer:
0.84 ; 0.0349545 ; symmetric
Step-by-step explanation:
Given that:
p = proportion of false alarm
Sample size (n) = 110
The mean of p
Since 84% of car buglar alarms turns out as false, then, the mean value of p = 0.84
To obtain the standard deviation ; we use the relation ;
√(p(1 - p) / n)
Standard deviation :
√0.84(1 - 0.84) / 110
√0.84(0.16) / 110
√0.1344 / 110
√0.0012218
= 0.0349545
np = 110 * 0.84 = 92.4 (distribution is symmetric or normal)

GRAPH IS IN THE PICTURE BELOW
Step-by-step explanation:
Assume that process that makes the parts can be altered to adjust the overall mean of the reflectiveness score. Also assume that if an individual part has a score less than 85, then the part is given a passing quality score. The adjusted value of the true mean in population S that would result in approximately 80% of parts from that population being given a passing score is:______
a. greater than 80
b. less than 80
c. equal to 80
Answers
Answer:
c. equal to 80
Step-by-step explanation:
Given that:
The population mean = 80
The standard deviation is = 6
The sample mean = 85
The objective is to find the probability that is less than 85
[tex]P(X < 85) = P( Z < \dfrac{x-\mu}{\sigma})[/tex]
[tex]P(X < 85) = P( Z < \dfrac{85-80}{6})[/tex]
[tex]P(X < 85) = P( Z < \dfrac{5}{6})[/tex]
[tex]P(X < 85) = P( Z < 0.833)[/tex]
From the standard normal table
P(X <85) = 0.7977
P(X< 85) = 79.77%
P(X< 85) = 80%
Therefore, The adjusted value of the true mean in population S that would result in approximately 80% of parts from that population being given a passing score is: equal to 80 .

Which statement is true for all triangles with exterior angle 1 and remote interior angles 2 and 3?
Answers
Answer:
The answer is below
Step-by-step explanation:
The measure of the exterior angle 1 of a triangle is equal to the sum of the corresponding interior angles 2 and 3.
This is evident in the Theorem 3 of a triangle
For example
Given a hypothetical triangle, with the following angle QRS, ∠1, ∠2, and ∠3 are interior angles. And ∠4, ∠5, and ∠6 are the three exterior angles.
We have the following ∠4 = ∠2 + ∠3
∠5 = ∠1 + ∠3
∠6 = ∠1 + ∠2
