-30<x/-4 answer must be simplified
Answer:
x<120
Step-by-step explanation:
-30<x/-4
In order to simplify this, we must isolate the x value by multiplying both sides by -4
Since we are dealing with inequalities and we are multiplying by a negative number, we have to switch the sign (<,>)
-30(-4)>x
x<120

A medical researcher needs 37 people to test the effectiveness of an experimental drug. If 101 people have volunteered for the test in how many ways can 37 people be selected
Answer:
The number of ways to select 37 people from 101 is, 5,397,234,129,638,871,133,346,507,775.
Step-by-step explanation:
In mathematics, the procedure to select k items from n distinct items, without replacement, is known as combinations.
The formula to compute the combinations of k items from n is given by the formula:
[tex]{n\choose k}=\frac{n!}{k!\cdot (n-k)!}[/tex]
Compute the number of ways to select 37 people from 101 as follows:
[tex]{101\choose 37}=\frac{101!}{37!\cdot (101-37)!}[/tex]
[tex]=\frac{101!}{37!\times 64!}\\\\=\frac{101\times 100\times 99\times....64!}{37!\times 64!}\\\\=5397234129638871133346507775[/tex]
Thus, the number of ways to select 37 people from 101 is, 5,397,234,129,638,871,133,346,507,775.

Jason bought a new truck at $25,000. The truck depreciates 15% of its value continuously each year. How much is it worth after 5 years? Round the answer to nearest dollar.
Answer:
A = $11093
Step-by-step explanation:
Given the following data;
Principal = $25,000
Rate = 15% = 15/100 = 0.15
Time, t = 5
To find the future value, we would use the compound interest formula;
[tex] A = P(1 + \frac{r}{n})^{nt}[/tex]
Where;
A is the future value. P is the principal or starting amount. r is annual interest rate. n is the number of times the interest is compounded in a year. t is the number of years for the compound interest.Substituting into the equation, we have;
r = -0.15 because it's depreciating.
[tex] A = 25000(1 + \frac{-0.15}{1})^{1*5}[/tex]
[tex] A = 25000(1 - 0.15)^{5}[/tex]
[tex] A = 25000(0.85)^{5}[/tex]
[tex] A = 25000*0.4437[/tex]
A = 11092.63 ≈ $11093
Therefore, the future value, A after 5 years is $11093.

40/10
4
Answer:
The mean is 4.
Step-by-step explanation:
When you add 3+0+4+7+0+4+5+3+6+8 you get 40 and because there are 10 numbers you would divide 40 by 10 and get 4.
Mean-the average of all of the numbers in a data set...to find the mean you simply add all of the given numbers together and then divide that sum by the total amount of numbers given, then you will get your mean.

Answer:
-54
Step-by-step explanation:
1.) 12-2/3x=48
2.) Multiple by 3 on both sides
36-2x=144
3.) Move the constant on the other side by subtracting it.
-2x=144-36
4.) Subtract numbers
-2x=108
5.) Divide both sides by -2
-2=108
÷2 ÷2
6,) Then you get x=-54

Which of the following is equivalent to 4x^2+4xy+y^2 ?
A) 4(x^2+y^2)
B) 4(x+y)^2
C) 2(x+y)^2
D) (4x+y^)2
E) (2x+y)^2
Answer:
E
Step-by-step explanation:
if we decidedly factor this expression-
4x^2+4xy+y^2
= (2x)^2 + 2*2xy + y^2
= (2x + y)^2
as you can see it is a perfect square so it can be grouped into (2x+y)^2
hence your solution is option e

daniel watched a beetle and a spider on the sidewalk. the beetle crawled 1/2 of a yard and the spider crawled 1/6 of a yard how much farther did the beetle crawl than the spider
Answer:
2 yards
Step-by-step explanation:
The beetle crawled 3 times more than the spider crawled.
The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.
Given that daniel watched a beetle and a spider on the sidewalk. the beetle crawled 1/2 of a yard and the spider crawled 1/6 of a yard.
The beetle crawled how many times is calculated as:-
Beetle crawled = ( 1 / 2 ) ÷ (1 / 6) x Spider crawled
Beetle crawled = 3 x Spider crawled
Therefore, the beetle crawled 3 times more than the spider crawled.

A local orange grower processes 2,330 oranges from his grove this year. The oranges are packaged in crates that each holds 96 oranges. All but one crate is full. How many oranges are in the last crate?
Answer:
13
Step-by-step explanation:
Given parameters:
Number of oranges processed by grower = 2330 oranges
Number of oranges per crate = 96
Unknown:
Number unpacked oranges
