Find the cardinal number for the set.
{27, 29, 31, 33, 35)
The cardinal number for the set is 5.
What is the cardinality of a set?
The size of a finite set (even comprehended as its cardinality) exists calculated by the number of elements it has. Remember that counting the number of elements in a set amounts to creating a 1-1 correspondence between its elements and the numbers in {1,2,...,n}.
The cardinal number (or cardinality) of set A, represented by n(A), exists as the number of distinct elements in set A
Since set A contains 5 distinct elements, then:
n(A) = 5
Therefore, the cardinal number for the set is 5.

Answer:
the correct choice is marked
Step-by-step explanation:
The lengths will form a right triangle if the squares of the two shortest legs total the square of the longest. The square of a root is the number under the radical, so you're looking to see if the two smallest numbers under the radicals total the largest number under the radical.
A: 22 +88 = 110 . . . . . a right triangle
B: 66 +99 = 165 ≠ 176 . . . . an obtuse triangle
C: 22 +110 = 132 ≠ 121 . . . . an acute triangle
D: 66 +77 = 143 ≠ 154 . . . . an obtuse triangle
_____
Additional comment
The largest angle is opposite the longest side. If the longest side is too long for the triangle to be a right triangle, then the opposite angle is larger than 90°, and the triangle is obtuse. If the longest side is too short for a right triangle, then the triangle is acute.

there is 30 gallons of water and 12 gallons of lysol in a cleaning mixture. what is the percent of the mixture is lysol?
Answer:
40%
Step-by-step explanation:
To find the percentage, set up a proportion!
12/30 = x/100
Now cross multiply!
30 · x = 30x
12 · 100 = 1,200
You are left with:
30x = 1,200
Divide both sides by 30...
And you get....
x = 40
The mixture is 40% lysol!
I hope this clears up any confusion you may have had :D

Scientists often use mice to study human disease and physiology. Parker et al. (2016) studied over 1000 newborn mice in order to better understand the genetic loci involved in many human diseases. As part of this study, the scientists snipped up to 5 mm from the end of each mouse's tail for the purpose of DNA collection. The scientists weighed each mouse immediately after snipping its tail. The provided data set lists the weights of the mice (in grams) after snipping.
Suppose the researchers wish to determine a range of plausible values for the weights of newborn mice with recently snipped tails. Use software to construct a 95% t-confidence interval for the population mean weight of newborn mice with snipped tails.
Complete the sentence to state how the researchers should correctly interpret the t-confidence interval.
The____that___of____is between the upper and lower limits of the confidence interval.
a. the true population mean weight.
b. the true sample mean weight.
c. researchers are 95% confident

bwo 1200 25.39 3.030 13.40 23.50 25.20 27.40 38.70
Using the t-distribution, it is found that the 95% t-confidence interval for the population mean weight of newborn mice with snipped tails is (42157, 42843).
The interpretation is: The researchers are 95% confident that the true population mean weight of newborn mice with snipped tails is between the upper and lower limits of the confidence interval.
We are given the standard deviation for the sample, which is why the t-distribution is used to solve this question.
The information given is:
Sample mean of [tex]\overline{x} = 42500[/tex].
Sample standard deviation of [tex]s = 6068[/tex].
Sample size of [tex]n = 1200[/tex].
The confidence interval is:
[tex]\overline{x} \pm t\frac{s}{\sqrt{n}}[/tex]
The critical value, using a t-distribution calculator, for a two-tailed 95% confidence interval, with 1200 - 1 = 1199 df, is t = 1.96.
The interval is:
[tex]\overline{x} - t\frac{s}{\sqrt{n}} = 42500 - 1.96\frac{6068}{\sqrt{1200}} = 42157[/tex]
[tex]\overline{x} + t\frac{s}{\sqrt{n}} = 42500 + 1.96\frac{6068}{\sqrt{1200}} = 42843[/tex]
The 95% t-confidence interval for the population mean weight of newborn mice with snipped tails is (42157, 42843).
The interpretation is that we are 95% sure that the population mean weight is in this interval, hence:
The researchers are 95% confident that the true population mean weight of newborn mice with snipped tails is between the upper and lower limits of the confidence interval.

Write an equation of the line that passes through (6, 1) and is perpendicular to x +2y-12=0.
Answer:
y = 2x - 11
Step-by-step explanation:
Perpendicular lines have negative reciprocal slopes—multiplying the slopes of two lines results in a product of -1.
Given the linear equation, x + 2y - 12 = 0, and the other point, (6, 1):
Convert the given linear equation into its slope-intercept form:
x + 2y - 12 = 0
Subtract x from both sides:
x - x + 2y - 12 = - x 0
2y - 12 = -x
Next, add 12 to both sides of the equation:
2y - 12 + 12 = -x + 12
2y = -x + 12
Divide both sides by 2 in order to isolate y:
y = - ½x + 6
Since the slope of the given equation is - ½, then the other line perpendicular to it must have a slope of 2:
Let m₁ = - ½
m₂ = 2
m₁ × m₂ = -1
-½ × 2 = -1
Hence, the slope of the other line, m₂ = 2. Next, using the slope of the other line, m₂ = 2, and the other given point, (6, 1), substitute these values into the slope-intercept form to solve for the y-intercept, (b):
y = mx + b
1 = 2(6) + b
1 = 12 + b
1 - 12 = 12 - 12 + b
-11 = b
Thus, the y-intercept of the other line is b = -11.
Therefore, the linear equation of the line that is perpendicular to x + 2y - 12 = 0 is:
y = 2x - 11.As a proof, attached is the graph of both equations, where it shows that they are perpendicular from each other.

6300kg in grams in standard form
Answer:
6300 kg is equivalent to 6.3·10^5 g
Step-by-step explanation:
Convert 6300 kg TO g in standard form. Recall that 1000 g = 1 kg.
1000 g
Multiplying 6300 kg by ------------- results in 63·10^4, or 6.3·10^5
1 kg
6300 kg is equivalent to 6.3·10^5 g.

Taylor has 4 1/3 inches of ribbon. If she was to cut some off to have 1 3/4 inches left, how much would she need to cut off?
Answer:
2 7/12
Step-by-step explanation:
4 1/3 - 1 3/4
you need a common denominator for 3 and 4 and the lowest would be 12
1/3 = 4/12
3/4 = 9/12
4 4/12 - 1 9/12
we can change 4 4/12 to be 3 16/12 by borrowing 12/12 or 1 from 4
3 16/12 - 1 9/12 = 2 7/12
