The square root of 1000 is between 28 and 32. so option D is correct.
How to find the closest integer less than and greater than the square root of a number?The function is strictly increasing function for x ≥ 0.
Assuming that all the values of x are ≥ 1, whenever there is increment in the value of 'x', the value of y increases too.
That means, we've got:
[tex]x_1 < x_2 < x_3 \implies \sqrt{x_1} < \sqrt{x_2} < \sqrt{x_3} \: \text{(such that } x_1 \leq 1[/tex]
Perfect square are those integers whose square root is an integer.
Let x-a be the closest perfect square less than x and let x+b be the closest perfect square more than x, then we get: x-a < x < x+b (no perfect square in between x-a and x+b, except possibly x itself).
Then, we get:
[tex]\sqrt{x-a} < \sqrt{x} < \sqrt{x+b}[/tex]
We need to find the square root of 1000
So, the square root of 1000 is 31.6227766017
[tex]\sqrt{1000} = 31.622[/tex]
Thus, The square root of 1000 is between 28 and 32. so option D is correct.

The square root of 1000 lies between 28 and 32, so the correct answer matches option D.
To determine the square root of 1000, we need to find two consecutive integers between which this value lies. We know that:
The square root of 900 (which is 30²) is 30.
The square root of 1024 (which is 32²) is 32.
Therefore, the square root of 1000 lies between 30 and 32.
This matches option D which states between 28 and 32.

9. Lula bought new furniture on her credit card for $993. If she pays it off in 6 months there will be no interest on her purchase. How much will her payments be if evenly distributed over 6 months?
Answer:
$165.50 dollars
Step-by-step explanation:
$993 / 6 = $165.50
Lula will need to pay $165.50 each month for 6 months to pay off her $993 furniture purchase without interest.
Lula purchased furniture on her credit card and plans to make payments over a period of 6 months with no interest charged. To calculate the monthly payment amount, you would divide the total cost of the furniture by the number of months over which she plans to pay.
The formula to find out the monthly payment is:
Monthly Payment = Total Cost / Number of Months
So for Lula, it looks like this:
Monthly Payment = $993 / 6
Monthly Payment = $165.50
Therefore, if Lula pays $165.50 each month, she will have the furniture paid off in 6 months without incurring any interest.

An article reports that blue eyed people earn less than brown eyed people, with these numbers: average blue-eyed salary $35,000, average brown-eyed salary $37,000, p-value 0.45. Based on that reported p-value, and using the common definition of "statistical significance," which is the case?

c.The results are just barely statistically significant.
d.The results are strongly statistically significant.
A group of 10 people is choosing a chairperson and vice-chairperson. They put all 10 people's names into a hat. The first name drawn becomes chair. The second name drawn becomes vice-chair. How many possible combinations of chair and vice-chair are there?
a.19
b.90
c.100
d.10! (10 factorial)
Answer:
a.
Step-by-step explanation:
A p-value less than 0.05 (typically ≤ 0.05) is statistically significant. It indicates strong evidence against the null hypothesis, as there is less than a 5% probability the null is correct (and the results are random). Therefore, we reject the null hypothesis, and accept the alternative hypothesis.
------------------------
First question:
The first question involves the test of an hypothesis.
Tests have significance levels, which normally are either 0.01, 0.05 or 0.1. If the p-value is less than the significance level, the results are significant, while if they are more, the results are not significant.
In this question, the p-value is 0.45, which is considerably more than any significance level, meaning that the results are nowhere near to being statistically significant, and the correct option is:
a. The results are nowhere near to being statistically significant.

Second question:
The order in which the people are chosen is important, as the first and second person chosen have different roles, and thus, the permutations formula is used.

For the geometric sequence: 112.5, 225, 450, 900,..., find the 21st term.
Answer:
Step-by-step explanation:
The 21st term of the given geometric sequence can be found by using the formula for the n-th term of a geometric sequence: a_n = a_1 * r^(n-1). In this case, it is 112.5 * 2^(21-1).
Explanation:In a geometric sequence, each term after the first is found by multiplying the previous term by a fixed, non-zero number called the common ratio. In this case, 225 divided by 112.5 gives us the common ratio of 2. Therefore, to find the 21st term of the given geometric sequence, we use the formula: a_n = a_1 * r^(n-1). Here, a_n is the n-th term, a_1 is the first term, r is the common ratio and n is the term which we want to find.
So, substituting the given values into the formula, a_21 = 112.5 * 2^(21-1). Calculate this and you'll have the 21st term of the geometric sequence.

6. The population of a town is 680 000 correct to the nearest 10 000. Write down
(a) The least possible population of the town.
(b) The greatest possible population of the town.
Answer:
a) 675 000
b) 685 000
Step-by-step explanation:
The population of a town is 680 000 correct to the nearest 10 000.
a) To find it lower bound, we level of accuracy by 2 and then subtract from 680 000
The lower bound is:
680 000-5000=675,000
Therefore the least possible population of the town is 675 000
b) We repeat the same process to find the upper bound
680 000+5000=685,000
The sum of two numbers is 14. The larger number minus three times the lesser number is -2. What is the lesser number?
A) 10
B) 12
C) 4
D) 3
Answer:
c) 4
Step-by-step explanation:
The sum of two numbers is 14. The larger number minus three times the lesser number is -2
To solve this question, we need to write the statement mathematically;
Let the two numbers be x and y
"The sum of two numbers is 14" can be mathematically written as x+y = 14
and
"The larger number minus three times the lesser number is -2" can be mathematically written as x - 3y = -2
x + y = 14 ------------------(1)
x - 3y= -2 -------------------(2)
Subtract equation (2) from equation (1)
[x - x = 0 y - (-3y)=4y 14-(-2)=16]
4y = 16
To get the value of y divide both-side of the equation by 4
4y/4 = 16/4
y = 4
Substitute y=4 into equation (1)
x + y =14
x +4 =14
Subtract 4 from both-side of the equation
x + 4 -4 = 10]-4
x = 10
x=10 and y =4
Therefore the lesser number is 4

The solutions to f(x) = 64 is x = 7 and x = –7.
Solution:
Given data:
[tex]$f(x)=x^{2}+15[/tex] and [tex]f(x)=64[/tex]
To find the solutions when f(x) = 64.
Both are equations of f(x), so equate the given equations, we get
[tex]x^2+15=64[/tex]
Subtract 15 from both sides of the equation.
[tex]x^2+15-15=64-15[/tex]
[tex]x^2=49[/tex]
49 can be written as 7².
[tex]x^2=7^2[/tex]
Taking square root on both sides of the equation, we get
x = ±7
The solutions to f(x) = 64 is x = 7 and x = –7.

The projected value (in millions of dollars) of a large manufacturing company is modeled by the function V(t) = 230(1.12)t, where V(t) is the value of the company t years after 2018. What does 230 represent in the function?
A) The growth factor of the company.
B) The value of the company in 2018.
C) The projected value of the company.
D) The value of the company after t years.
230 is the value of the company in 2018.
Option (B) is correct.
To find 230 represent in the function.
What is arithmetic?science that deals with the addition, subtraction, multiplication, and division of numbers.
It is given that:
The equation of a exponential growth function is equal to
[tex]V(t)=a(1+r)^{t}[/tex]
where,
V(t) is the value of the company
t is the number of years after 2018
a is the initial value or y-intercept
r is the rate of change
Put the value,
a=230
1+r=1.12
r=1.12-1=0.12
r=12%
so 230 is the value of the company when the value of t is equal to zero.
Remember that t is the number of years since 2018
Therefore ,230 is the value of the company in 2018.

Two secants drawn from an external point to the circle.
The (outside ) × (whole) of one secant is equal to the (outside) × (whole) of the other secant, that is
(x + 2)(x + 2 + 2x - 8) = (x + 1)(x + 1 + 2x - 5)
(x + 2)(3x - 6) = (x + 1)(3x - 4) ← expand both sides using FOIL
3x² - 12 = 3x² - x - 4 ( subtract 3x² - x - 4 from both sides )
x - 8 = 0 ( add 8 to both sides )
x = 8

Answer:
[tex]B) \frac{DE }{EA} =\frac{CB}{AC}[/tex]
Step-by-step explanation:
If ant two given triangles are SIMILAR, then they have equal corresponding angles and their corresponding sides are PROPORTIONAL.
For example: if Δ ABC ≈ Δ PQR, then
∠A = ∠P , ∠B = ∠Q and ∠C = ∠R
