Answer:
it is greater than ten and less than 100, the answer is 30%
Step-by-step explanation:
600*5=3000
3000/100=30%
1-5x-2y =-22
a) (-4,-6)
b) (6,4)
According to the system:
5 – 7x + 2y² = -10
1 – 5x – 2y = -22
______________
a) No ; (4, 6) is not a solution to the
system. This point does not touch either equation.
b) No ; (6, 4) is not a solution to the system. This point does not touch either equation.
Solutions:
x = ( 122 ∓ 3√101 ) / 25 ≈ 3.674 or 6.086
y = ( -7 ± 3√101 ) / 10 ≈ 2.315 or -3.715
Answer:
relationships between two variables where their ratios are equivalent. Another way to think about them is that, in a proportional relationship, one variable is always a constant value times the other.
Step-by-step explanation:
3/4 of an hour is equal to 45 minutes.
To find 3/4 of an hour, we need to multiply the value of one hour by 3/4.
One hour is equal to 60 minutes.
To calculate 3/4 of an hour:
= 3/4 x 60 minutes
= (3/4) x 60
= 45 minutes.
Therefore, 3/4 of an hour is equal to 45 minutes.

Answer:
3.52
Step-by-step explanation:
Calculation to Find the mean for the random variable X
Using this formula
Mean(μ) =(n*p)
Where,
n=16
p=22% or 0.22
Let plug in the formula
Mean(μ)=16×0.22
Mean(μ)=3.52
Therefore the mean for the random variable X will be 3.52
Answer: 9
Step-by-step explanation: The reason that students get intimidated
by word problems is they try to look at all the information at once.
The best way to approach a word problem
is to break it down sentence by sentence.
In this problem, let's look at the first part of the sentence.
We know that six less than three times a number is 21.
Let's call the number x.
So we know that six less than three times a number means 3x - 6.
A common mistake would be for students to put 6 - 3x.
However, the word "less than" switches the order around.
So we know that six less than three times a number is 21.
So we can write this as 3x - 6 = 21.
Now we have an equation and we can solve for x.
First add 6 to both sides to get 3x = 27.
Now divide both sides by 3 to get x = 9.
So our answer to this word problem is 9.
