Answer:
Jay is 18
Step-by-step explanation:
Because if Nadia is 6 and Jay is 3 times her age, then he would be 18.
Also, you add 10 to both of their ages, there is an age gap of 12 years.
5 : 3 = 45 : 27
3/5 = 27/?
3 × 9 = 27 5 <span>× 9 = 45
5 : 3 = 45 : 27
45 boys</span>
So there are two ways.
First you could solve for y and plug it into the calculator. one equation for y1 and another for y2. Then go 2nd trace and press 5 and then press enter 3 times to find the intersection.
the second way is to solve by hand. I would suggest solve the first equation for y and plug the equation solved for y into the other equation. so y = -3x + 9 and 3x-5y=15. Then you could do 3x - 5(-3x+9) = 15. Finally solve for x and plug in x into both equations to see if you get the same y value.
The answer should be (10/3, -1)
Answer:
See explanation.
Step-by-step explanation:
First put 2x-4 equal to 0 and solve it.
2x-4=0
2x=4
x=2
Now plug 2 into the polynomial and see if it equals to 0
In case it's not, then it is not a factor of it
2(2)^5 - 4(2)^4 + 2x^2 -2(2) - 4 = 0
So it's indeed a factor of the polynomial.
Hope this helps!
Answer: 0.77
Step-by-step explanation:
Given : The number of interior designers = 400
The number of interior designers prefer red = 92
The number of interior designers do not prefer red =
Now, the probability that a designer does NOT prefer red is given by :-
Hence, the probability that a designer does NOT prefer red = 0.77
