742,617 to the nearest ten tousand
Answer:
740,000
Step-by-step explanation:
The ten-thousands digit is the 4.
Change all digits to the right of the 4 to 0.
742,617 becomes 740,000.
Since the first digit to the right of the 4 is 2, and not a digit from 5 through 9, we keep the 4 and do not change it to 5.
Answer: 740,000
Answer:
the answer is 740000

Answer:
[tex]x=\begin{bmatrix}-2\\-1\\\end{bmatrix}[/tex]
Step-by-step explanation:

Isolate the X
=> [tex]\left(x+2\right)\left(x+1\right)=0[/tex]

Is this a fair or biased sample.
A store owner wants to survey customers about the products he sells. He programs the computer to select 100 customers from the mailing list and sends them each a survey.
(I'm torn on this one because on one hand, he's only selecting customers from his mailing list which makes me think biased, on the other he is using the computer to randomly select them so that seems fair. Also, of the people who are sent the surveys, everyone may not apply. So I'm leaning towards biased.)
Answer:
biased
Step-by-step explanation:
even with the computer randomly picking people, they are still all on the mailing list.

Answer:
(3, -9)
Step-by-step explanation:
5x + y = 7
-x - 2y = - 15
What we can do is multiply the second equation by 5, as we try to combine both equations to get rid of x.
5x + y = 6
-5x - 10y = 75
-9y = 81
y = -9
Now we plug y back in.
5x - 9 = 6
5x = 15
x = 3

Two laboratory technicians are running product quality tests . One technician takes 6 minutes less than the other . What equation would give the amount of time , t , it would take to run the tests if the technicians work together to split the work on the different tests ? 1/(6t) = 1/x - 1/(x - 6) B 1/t = 1/x + 1/(x - 6) Oct t = x + x - 6 1/t = 1/x - 1/(x - 6)
Answer:
C. t = x + x - 6Step-by-step explanation:
Let the time use by other one technician be x
if the other technician takes 6 minutes less than the first technician, then the time taken by the other technician will (x - 6)
The total amount of time t it would take to run the tests if the technicians work together will be expressed by taking the sum of the time taken by the two technician as shown.
First technician = x
Second technician = x-6
Sum of the time taken
t = x+ (x-6)
Hence option C is correct

About 8% of the population of a large country is math phobic. If two people are randomly selected, what is the probability both are math phobic? What is the probability at least one is math phobic?
Answer:
the chances both are is=.64%
the chances of only one is=15.36%
Step-by-step explanation:
8%=.08
.08x.08= .0064=.64%
1-(1-0.08)×(1-0.08)
1-.92x.92
0.1536=
15.36%
a) The probability both are math-phobic: 0.0064 or 0.64%.
b) The probability that at least one is math-phobic is 0.1536 or 15.36%.
To determine the probability that both selected people are math-phobic, we can use the multiplication rule of probability.
Since the selection is random, the probability that the second person is math-phobic is also 0.08.
To find the probability that both events occur, we multiply the individual probabilities:
Probability of both being math-phobic = 0.08 x 0.08 = 0.0064
Therefore, the probability that both selected people are math-phobic will be 0.0064 or 0.64%.
To find the probability that at least one person is math-phobic, we can use the complement rule of probability.
The probability that the first person is not math-phobic ;
1 - 0.08 = 0.92.
Similarly, the probability that the second person is not math-phobic is also 0.92.
Probability of none being math-phobic = 0.92 x 0.92 = 0.8464
Probability of at least one being math-phobic = 1 - 0.8464 = 0.1536
Therefore, the probability that at least one person is math-phobic is 0.1536 or 15.36%.

Alvin is 15 years younger than Elga. The sum of their ages is 45. What is Elga's age?
Answer:
Elga is 30 and Alvin is 15
Step-by-step explanation:
45-15=30
30-15=15
30+15=45
Answer:
[tex]\huge\boxed{\text{Alvin = 15, Elga = 30}}[/tex]
Step-by-step explanation:
In order to find Alvin and Elgas age, we can use a system of equations.
Let us assume that [tex]a[/tex] represents Alvin's age and [tex]e[/tex] represents Elgas age.
We can create two equations:
[tex]a = e-15[/tex]
[tex]a+e=45[/tex]
We can now use substitution to find each value. Let's substitute [tex]a = e-15[/tex] into [tex]a+e=45[/tex] as a.
[tex](e - 15) + e = 45[/tex]
We can now simplify this equation and solve for e.
[tex]2e-15 = 45\\2e = 60\\e = 30[/tex]
So we know that Elga is 30 years old. To find Alvin's age, we can substitute the value of e (30) back into one of the equations. Let's do it for [tex]a+e=45[/tex].
[tex]a + 30 = 45\\a = 45-30\\a=15[/tex]
So Elga is 30 years old and Alvin is 15 years old.

What value of k makes the equation true?
k – 3(k + 5) – 0.5 = 3(0.25k + 4)
Answer:
k = - 10
Step-by-step explanation:
k - 3(k + 5) - 0.5 = 3(0.25k + 4) ← distribute parenthesis on both sides
k - 3k - 15 - 0.5 = 0.75k + 12
- 2k - 15.5 = 0.75k + 12 ( subtract 0.75k from both sides )
- 2.75k - 15.5 = 12 ( add 15.5 to both sides )
- 2.75k = 27.5 ( divide both sides by - 2.75 )
k = - 10

Write an expression for the
product of 4 and m.
Answer:
4m
Step-by-step explanation:
Expressions do not have equal signs, So for the product of 2 things we just multiply them together.
4m
Answer:
4 × M = P
Explanation:
A product is the result of a multiplication expression, so in this case, We're using variables to represent numbers.
P = Product
We're multiplying 4 and M, so lets rewrite this.
4 × M
This is an incomplete expression, but what will we use for our product We can use a variable. Our variable is P. So lets complete this expression.
4 × m = p.
Or, we can put it in a less complex way.
4m.
This also is a incomplete expression, but it means 4 × m.
