Round 452,906 to the nearest hundred thousand, ten thousand, thousand, hundred, ten
Rounding 452,906 to each place is
(a) to nearest hundred thousand is 500,000
(b) to nearest ten thousand is 450,000
(c)to nearest thousand is 453,000
(d) to nearest hundred is 452,900
(e) to nearest tens is 452,910
Given :
Round the number 452,906 to each place given below
(a) Round to nearest hundred thousand
In the given number , 4 is in hundred thousand's place
To round to nearest hundred thousand, we look at the number in ten thousands place that is 5. 5 is equal to 5. So we add 1 with the number in hundred thousand . write 0 in remaining places
452,906, Round to nearest hundred thousand is 500,000
(b) To round to nearest ten thousand, we look at the number in thousands place that is 2. 2 s less than 5. So we keep 5 in ten thousands place . write 0 in remaining places
452,906, Round to nearest ten thousand is 450,000
(c)To round to nearest thousand, we have 9 in hundreds place that is greater than 5. So add 1 with 2 and write 0 in remaining places
452,906, Round to nearest thousand is 453,000
(d) To round to nearest hundred, we have 0 in tens place that is less than 5. So write 9 as it is and 0 in remaining places
452,906, Round to nearest hundred is 452,900
(e) To round to nearest ten , we have 6 in one's place that is greater than 5.
So add 1 with 0 and write 0 in one's place
To round to nearest thousand, we have 9 in hundreds place that is greater than 5. So add 1 with 2 and write 0 in remaining places
452,906, Round to nearest tens is 452,910

You asked a sample of individuals what kind of animal is their favorite. Of the 167 individuals in your sample, 52 of them answered "dog". Which of the following gives a 95% confidence interval for the true percentage of individuals whose favorite animal is a dog
a. (23.4%, 38.9%)
b. (16.8%, 32.3%)
c. (3.1696, 3.2696)
d. (2.21%,4.21%)
Answer:
a. (23.4%, 38.9%)
Step-by-step explanation:
Р = x/∝ = 52/167 = 0.3114
At 95% confidence level
∝ = 1 - 0.95 = 0.05
Zerit = Z0.05/2 = 1.96
Р ± Zerit [tex]\sqrt{P(1-P) / n}[/tex]
= 0.3114 ± 1.96 [tex]\sqrt{0.3114(1-0.3114) / 167}[/tex]
= 0.3114 ± 0.0702
= 0.2412 or 0.3816
= 24.1% or 38.1%
Closest Option = 23.4%, 38.9%
A 95% confidence interval for the true percentage of individuals whose favorite animal is a dog is (23.4%, 38.9%)
The formula for calculating the confidence interval based o proportion is expressed according to the formula:
[tex]p\pm z\sqrt{\frac{p(1-p)}{n} }[/tex]
z is the z-score at 95% confidence interval
p is the proportion
n is the sample size
Given the following parameters
p = 52/167 = 0.31
z = 1.96
n = 167
Substitute the given parameters into the formula to have:
[tex]CI=0.31 \pm 1.96\sqrt{\frac{0.31(1-0.31)}{167} } \\CI=0.31 \pm 1.96\sqrt{\frac{0.31(0.69)}{167} } \\CI=0.31 \pm 1.96(0.035)\\CI=0.31\pm 0.0701\\CI = (0.31-0.0701, 0.31+0.0701)\\CI=(0.234, 0.389)[/tex]
Hence a 95% confidence interval for the true percentage of individuals whose favorite animal is a dog is (23.4%, 38.9%)

Ashley's Internet service is terribly unreliable. In fact, on any given day, there is a 25 % chance that her Internet connection will be lost
at some point that day. What is the probability that her Internet service is not broken for five days in a row? Enter a fraction or round
your answer to 4 decimal places, if necessary.
Answer:
The probability that her internet service will not be broken for five days in a row is 243/1024
Step-by-step explanation:
Here, we want to calculate the probability that her internet service is not broken for five days in a row
Let the event that her internet will be broken be B and the event that her internet will not be broken be N
P(B ) = 25% = 0.25
P(N) = 1-0.25 = 0.75 = 3/4
Thus, the probability that her internet is not broken for five days in a row = P(N) * P(N) * P(N) * P(N) * P(N)
= 3/4 * 3/4 * 3/4 * 3/4 * 3/4 = 243/1024
Describe the transformation of the graph of the parent function y = √x for the function y = √x + 7 + 5.
Answer:
First part 7 units left and 5 units up
The 2nd part is v ≥-7 and the third part is Y≥5
Step-by-step explanation:
Done it in Edge and got it right :)
The transformation of parent function [tex]y = \sqrt{x }[/tex] to [tex]y = \sqrt{x + 7} + 5[/tex] is first translated 7 units left and then it translated 5 units up.
What is function?"It defines the relation between input and output values.""In function, for each input there is exactly one output."What is transformation of function?"It is nothing but mean transforming the function from one form to another."
For given question,
We have been given a function [tex]y=\sqrt{x}[/tex]
We need to describe the transformation of the graph for the function [tex]y = \sqrt{x + 7} + 5[/tex]
We know, if f(x) is transformed to f(x + a) then it means function f(x) is translated 'a' units left.
So, [tex]y=\sqrt{x+7}[/tex] means the function [tex]y = \sqrt{x}[/tex] is translated 7 units left.
We know, if f(x) is transformed to f(x ) + a then it means function f(x) is translated 'a' units up.
So, [tex]y = \sqrt{x + 7} + 5[/tex] means the function [tex]y = \sqrt{x + 7}[/tex] is translated 5 units up.
Therefore, the parent function [tex]y = \sqrt{x }[/tex] is first translated 7 units left and then it translated 5 units up.

If f(2) = 12 and f '(x) ≥ 3 for 2 ≤ x ≤ 5, how small can f(5) possibly be?
Answer:
21
Step-by-step explanation:
From our previous knowledge, if f'(x) = m ,
Then f(x) = mx+c
For a smaller value of f(5), m should be the smallest possible integer if m = 3
i.e. f(x) = 3x+c
replacing the value of x with 2 given from the question to get the value of c, we have:
f(x) = 3x+c
f(2) = (3×2)+c
where; f(2) = 12
12 = 6+c
- c = -12 + 6
- c = - 6
c = 6
Now, f(x) can now be;
f(x) = 3x + 6
f(5) = (3×5)+6
f(5) = 15 + 6
f(5) = 21
Therefore, smallest possible value of f(5) is 21

g(x) = x - 3
f (x) = x3 + 4x
Find g(x) - f (x)
Answer: g(x)-f(x)=-x³-3x-3
Step-by-step explanation:
Since we are given g(x) and f(x), we can directly subtract them to find g(x)-f(x).
x-3-(x³+4x) [distribute -1]
x-3-x³-4x [combine like terms]
-3-x³-3x [rewrite]
-x³-3x-3
Now, we know that g(x)-f(x)=-x³-3x-3.

Kai had a gross weekly paycheck of $616 last week. Kai worked 6 hours for 4 of the days and 8 hours on 1 day. What is Kai's hourly rate of pay? a. $16.21 b. $19.25 c. $20.53 d. $25.67 Please select the best answer from the choices provided
The correct answer is B. $ 19.25
Explanation:
To calculate the hourly rate of pay, first, let's calculate the total number of hours Kai worked, and then divide the total earned into the number of hours.
6 hours x 4 days = 24 hours
8 hours x 1 day = 8 hours
24 hours + 8 hours = 32 hours
This shows Kai worked a total of 32 hours. Now to find the hourly rate of pay, follow this procedure:
$616 (total earned) ÷ 32 hours = $19.25 each hour
This means Kai earns $19.25 for each hour of work and therefore the hourly rate of pay is $19.25.

what are prime numbers?
Answer:
A prime number is a natural number greater than 1 that is not a product of two smaller natural numbers.
Answer:
Prime numbers are positive integers that have only 2 factors: Itself, and 1.
For example, 13 is a prime number because it has only 2 factors that are: 1 and 13.
1 is NOT a prime number as it only has 1 factor which is 1.
