Answer:
Your answer is x=3
Step-by-step explanation:
So you have the equation 2x+5=11
First, subtract 5 from 5 and from 11.
Then you will cancel out the 5's.
After that, you should have "2x=6"
Now divide 2 from 2x and from 6.
Your answer is x=3
The conditional probability that the carbon emission is beyond the permissible emission level and the test predicts this is given by:
a. 0.2975.
<h3>What is Conditional Probability?</h3>
Conditional probability is the probability of one event happening, considering a previous event. The formula is:
In which:
- P(B|A) is the probability of event B happening, given that A happened.
- is the probability of both A and B happening.
- P(A) is the probability of A happening.
In this problem, we have that the events are as follows:
- Event A: Carbon emission beyond the permissible emission level.
- Event B: Test predicts this.
We have that 35% of the units have carbon emission beyond the permissible emission level, and the test is 85% accurate, hence:
Then:
Which means that option a is correct.

An undefined slope indicates that the line in question is vertical. According to the point (7,-3), this line is described by x = 7.
Answer:
112 dimes and a nickel.
because, one, 110 dimes equals 11.00 (so add the2 extra dimes.)
two, the .05 is a nickel not a .5 dime.
So that's your answer. 112 dimes and 1 nickel.
Answer:
D.
Step-by-step explanation:
In order to answer this question we need to know the definition of the domain. The domain of a function is the complete set of possible values of the independent variable ("x"). In our case we can look at the function and cross out option "A" because the function has no point with a negative "x" value. Option "B" can be also crossed out because it states that "x" values can not go above 3 but by looking at the function we can see multiple point with "x" values larger then 3. Option "C" can also be crossed out because their is not point on the function that would have a negative "x" value which contradicts the statement about all numbers. And finally we are left with "D" and we know it is the right answer since the function has a point with "x" value being equal to 0 and the all other points have the "x" value greater then 0, which is exactly what option "D" states.
