Answer:

The value of b is 19.

Step-by-step explanation:

With what the problem states, we have that:

\frac{4b + 19}{6b + 11} = 0.76

Doing cross multiplication

4b + 19 = 0.76(6b + 11)

4b + 19 = 4.56b + 8.36

4.56b - 4n = 19 - 8.36

0.56b = 10.64

b = \frac{10.64}{0.56}

b = 19

The value of b is 19.

A box contains 24 yellow, 33 green and 35 red jelly beans. If 8 jelly beans are selected at random, what is the probability that
tensa zangetsu [6.8K]

Answer:

0.00014

Step-by-step explanation:

The box contains a total of 24 + 33 + 35 = 92 jelly beans

If we need to pick 8 jelly beans and want them all to be green:

We can choose 8 green jelly beans from 33 green in  C₃₃,₈ different ways

The total ways we can choose 8 jelly beans out from 92 is: C₉₂,₈

Thus, the probability we're looking for is C₃₃,₈ / C₉₂,₈ = 13884156/93080887185 =0.00014

Suppose the students who scored 85 and 90 on the math test take the test again and score 95 how manu stars would you have to add
Akimi4 [234]
In this question, each star equal to 4 students. If the people on 85 and 90 take the test again that means their number should be 14+4 people= 18 people. 
If they all get 95, then it means we need to add 18 people to the 95 graph. The number of stars would be: 18 people / (4people/stars)= 4.5 stars

If you add the stars graph it will be easier. It should be clear that 85 will have 1 stars and 90 have 3.5 stars. Adding them up will be 1 stars + 3.5 stars= 4.5 stars
