Answer:
There were approximately 53 cases of measles before the increase.
Step-by-step explanation:
Since there was an increase of 10.2% this means that the value we have now is the value we had prior plus the increase, in other words this is 100% of the cases before the increase plus 10.2%, so we have now 110.2% of cases. We know that this value represents 58 cases, so we can use a rule of three in order to determine the prior value. This is seen bellow:
100% -> x
110.2% -> 58
110.2*x = 100*58
x = 5800/110.2 = 52.63
Which is approximately 53 cases.
Step-by-step explanation:
come on, you should really be able to answer these things yourself now !
in such cases the total is not the whole class, but the sum of all students that satisfy a certain basic criteria. in this case it is "did not complete the homework".
now, from all the students that did not complete the homework (3+5 = 8), how many have still passed the test ?
3.
so the probability to still pass the test although the homework was not completed is
3/8
Answer:
0.30
Step-by-step explanation:
They are independent, so:
P(A and B) = P(A) P(B)
0.24 = 0.80 P(B)
P(B) = 0.30
The equation for monthly payment is b = 49.05M.
<u>SOLUTION:</u>
Given, a cellular family phone plan cost $49 per minute plus five cents per minute of long distance service. We have to write an equation for the monthly payment b when M minutes of long distance service are used.
Now, given that,
<em>Equation:</em>
An equation is a statement that the values of two mathematical expressions are equal <em>(indicated by the sign =)</em>
