Answer:
x = 25
Step-by-step explanation:
Since the triangles are congruent then corresponding angles are congruent.
That is ∠ D and ∠ B are corresponding angles and congruent, thus
4x - 20 = 2x + 30 ( subtract 2x from both sides )
2x - 20 = 30 ( add 20 to both sides )
2x = 50 ( divide both sides by 2 )
x = 25
Remember PEMDAS (Parenthesis, Exponents, Multiplication, Divison, Addition and Subtraction)
Also note that Multiplication and Division needs to be done left to right and the same goes for Addition and Subtraction.
So in your problem, the first operation we need to do is division.
68 - (18/3) x 6
68 - 6 x 6
Now we do multiplication
68 - 6 x 6
68 - 36
Finally we do subtraction because that's the only operation we have left to do
68 - 36 = 32
So your answer should be 32.
Answer:
I got (y-7)=1/13(x+6) for point slope
and y=1/3x+13 for slope intercept form
double check me though I'm new at this
Answer:
$30,000
Step-by-step explanation:
There are 60 minutes in an hour. There are 30 two minutes in 60 minutes. 30*1,000 = 30,000.
Answer:
0.9648
Step-by-step explanation:
Given that:
p = 0.2
Sample size = Number of trials (n) = 15
Probability that atleast one person is infected.
This can be solved using the binomial probability function :
P(x = x) = nCx * p^x * (1 - p)^(n-x)
P(x ≥ 1) = p(1) + p(2) + p(3) +... + p(15)
The sum of the individual probabilities of p(1) up to p(15)
Therefore, to save computation time, we can use the binomial probability calculator :
P(x ≥ 1) = 0.9648
