Answer:
√25 is a rational number
√1 is rational number
√7 is irrational number
Step-by-step explanation:
first one is √25
=√25
=√5² ( 25 is the square of 5)
= 5
another one is √1
= √1
=√1² ( 1 is the square of itself)
= 1
last one is √7..... and it is irrational

Standing side by side, a woman casts a 41.4-inch shadow and her 40-inch-tall son casts a 24-inch shadow. What is the height of the woman to the nearest inch?
Answers
Answer:
25 inches
Step-by-step explanation:
Given
Son:
[tex]Height = 40\ inch[/tex]
[tex]Shadow = 24\ inch[/tex]
Woman:
[tex]Height = 41.4\ inch[/tex]
Required
Determine the height of the woman's shadow
From the question, the height is directly proportional to the height of the shadow:
So, we have:
[tex]40\ inch = 24\ inch[/tex] --- For the son
and
[tex]41.4\ inch = x[/tex]
Where x represents the shadow of the woman
Cross Multiply:
[tex]x * 40 = 24 * 41.4[/tex]
[tex]x * 40 = 993.6[/tex]
[tex]40x = 993.6[/tex]
Make x the subject
[tex]x = 993.6/40[/tex]
[tex]x = 24.84[/tex]
[tex]x = 25[/tex] ---- approximated
Hence, the woman's shadow is 25 inches tall

How to interpret integral multiplication?Suppose that there are two positive integer numbers( numbers like 1,2,3,.. ) as a and b
Then, their multiplication can be interpreted as:
[tex]a \times b = a + a + ... + a \: \text{(b times)}\\\\a \times b = b + b +... + b \: \text{(a times)}[/tex]
For example,
[tex]5 \times 2 = 10 = 2 + 2 + 2 + 2 + 2 \: \text{(Added 2 five times)}\\or\\5 \times 2 = 10 = 5 + 5 \: \text{(Added 5 two times)}[/tex]
Given;
From 100 to 10^6;
100 * 10^4 = 10^6
From 100 to 90;
100/10*9=90
From 90 to 100
90/9*10=100
From 10^6 to 100
10^6/10^4=100
Therefore, by multiplication or division will be 10^6/10^4

Please I need help with this question.
In the store Sara is shopping at, 1 cardboard box with glitter is $10 per box. The other type of cardboard box is $6 per box that has no design. If Sara spent $130, how much of boxes did she get (what type)? What quantity?
Answers
Answer:
(There are so many answers to this question) she could have gotten 13 glitter boxes and none of the other boxes.
Step-by-step explanation:
13x10=130
Answer: 13 glitter cardboard boxes that are $10
Step-by-step explanation:
We have to divide the number $130 by both numbers each cardboard box costs, designed glitter boxes that are $10 and plain cardboard boxes are 6 each. So, let's do that right now.
130 ÷ 6 = 23.333
Sara only bought 13 cardboard boxes, so it is no the answer.
Now, let's try the second number that is $10. We have to remember that the answer has to be 13. So, let's do that as well right now.
130 ÷ 10 = 13
We see that we get 13 while we divide 130 by 10, so Sara bought 13 designed glitter cardboard boxes.
The answer to the question is 13 glitter cardboard boxes that are $10.
Hope this helps you!

3. From the table below, find Prof. Xin expected value of lateness. (5 points) Lateness P(Lateness) On Time 4/5 1 Hour Late 1/10 2 Hours Late 1/20 3 Hours Late 1/20
Answers
Answer:
The expected value of lateness [tex]\frac{7}{20}[/tex] hours.
Step-by-step explanation:
The probability distribution of lateness is as follows:
Lateness P (Lateness)
On Time 4/5
1 Hour Late 1/10
2 Hours Late 1/20
3 Hours Late 1/20
The formula of expected value of a random variable is:
[tex]E(X)=\sum x\cdot P(X=x)[/tex]
Compute the expected value of lateness as follows:
[tex]E(X)=\sum x\cdot P(X=x)[/tex]
[tex]=(0\times \frac{4}{5})+(1\times \frac{1}{10})+(2\times \frac{1}{20})+(3\times \frac{1}{20})\\\\=0+\frac{1}{10}+\frac{1}{10}+\frac{3}{20}\\\\=\frac{2+2+3}{20}\\\\=\frac{7}{20}[/tex]
Thus, the expected value of lateness [tex]\frac{7}{20}[/tex] hours.
An expected value is the theoretical mean value of a numerical experiment over many repetitions of the experiment.
Expected value of lateness is [tex]\frac{7}{20}[/tex] hours.
Let us consider, P(x) is represent that probability of lateness and x represent number of hours late.
So, below a table is formed.
x 0 1 2 3
P(x) 4/5 1/10 1/20 1/20
From formula of expected value,
E(x) = ∑ x P(x)
[tex]E(x)=(0*\frac{4}{5} )+(1*\frac{1}{10} )+(2*\frac{1}{20} )+(3*\frac{1}{20} )\\\\E(x)=0+\frac{1}{10}+\frac{1}{10}+\frac{3}{20} \\\\E(x)=\frac{7}{20}[/tex]
So, expected value of lateness is 7/20 hours.

Answers
Answer:

Step-by-step explanation:
Answer:
No solutions
Step-by-step explanation:
Real number solutions only or real and complex solutions. A solution to the system:
y=-2x+2
y=x2-2x+4
is the value of x such that when you plug it into both equations, they both produce the same value of y, or the value of x such that
-2x+2=x2-2x+4
solving this equation----------> x2=-2, taking square root of both sides gives x= ±√2i, or the system has no real solutions but has 2 complex solutions. If you graph both functions in the xy-plane, where x, y are real numbers, you' ll see they do not intersect, which implies there is no real number solutions.
