I think the answer is ur dad
Answer:
I Believe it is 70
Step-by-step explanation:
30 / 6 = 5
375 / 5 = 75
75 - 5 = 70
Here's the first part:
y = 8x - 9 --(i)
y = 4x - 1 -- (ii)
then in eqn( i),
4x - 1 = 8x -9 (from eqn( ii) )
-1 +9 = 8x -4x
8 = 4x
x =2
then in eqn (i),
y = 8*2 -9
= 16 -9
= 7
The 2nd part:
When these two equations are graphed, at point (2,7) the lines representing the two equations intersect because these values (2,7) satisfies the given equations.
Answer:
(a) The probability is 0.64
(b) The probability is 0.59
Step-by-step explanation:
Say that an order requests at least one optional feature is equivalent to say that an order request one or more than one optional feature, So the probability can be calculated as the sum of this two proportions:
P = 0.23 + 0.41 = 0.64
Where 0.23 is the proportion or probability that an order request one optional feature and 0.64 is the probability that an order request more than one optional feature.
On the other hand, say that an order does not request more than one optional feature is equivalent to say that an order request zero or one optional feature, So the probability in this situation can be calculated as the sum of:
P = 0.36 + 0.23 = 0.59
Where 0.36 is the probability that an order doesn't request optional features and 0.23 is the probability that an order request one optional feature.
The domain of a function is defined as the set of values of x that will give out a real value of y, a "real" number is basically a number that can be expressed as itself instead of as a symbol or a calculation, for example -4 would be a real number as we can simply express it as -4, however √-4 would not be a real number as it would be expressed as 2i. For the function y=25-x all values of x will result in a real number therefore we say domain of f(x) is x∈R, or simply saying "the domain of the function y=25-x is all real values of x" will probably suffice.
