Answer:


Step-by-step explanation:

First, we need to add all the jellybeans together to find the chances of a specific bean per type out of all of them.

42 + 45 + 20 + 32 = 139 beans

So now we have to decide individually the probabilities of the two types

The probability of getting a purple bean is equal to

32/139  and the probability of NOT getting a red bean is equal to

97/139

So now you just add them together:

32 + 97 = 129/139

And the percentage of that would be approximately 92.81%

Answer:

\frac{129}{139}

Step-by-step explanation:

Given,

In the bag,

Red candies = 42,

Green candies = 45,

Yellow candies = 20,

Purple candies = 32,

So, the total candies = 42+45+20+32=139

⇒ The probability of purple candies = \frac{32}{139}

Also, the probability of red candies = \frac{42}{139}

⇒ The probability that candy is not red = 1 - the probability of red candies

=1-\frac{42}{139}

=\frac{139-42}{139}=\frac{97}{139}

Hence, the probability that it is purple or not red is,

P (purple or not red) = The probability of purple candies + The probability that candy is not red

=\frac{32}{139}+\frac{97}{139}

=\frac{129}{139}

An aptitude test has a mean score of 80 and a standard deviation of 5. The population of scores is normally distributed. What ra
sdas [7]

Answer:

82.62

Step-by-step explanation:

Mean score (μ) = 80

Standard deviation (σ) = 5

The 70th percentile of a normal distribution has an equivalent z-score of roughly 0.525.

For any given score, X, the z-score can be determined by:

z=\frac{X-\mu}{\sigma}

For z = 0.525:

0.525=\frac{X-80}{5}\\ X=82.62

A raw score of approximately 82.62 corresponds to the 70th percentile.

Multiple Choice!!! A school bought a special type of lock for all student lockers. Every student had to create his or her own pa
Elina [12.6K]
<span>Say the code only needed to be one number long. Going from 0-9, there are ten digits. Therefore, there are ten unique codes.

Now say the code has to be two numbers long. There are ten possibilities for the first digit, 0-9. But the second digit only has nine possibilities, since each number has to be different. (The first number might be 0, so the second can only go from 1-9) For each of the first ten possibilities, there are nine possibilities for the second. We multiply those two numbers together, 10 * 9, and we get 90.

Now we just extend the logic. The third number only has eight possibilities, while the fourth number only has seven. 10 * 9 * 8 * 7 = 5040 possible codes. I hope this helped! has a great day! :)</span>

there are 26 third graders and 32 fourth graders going on a field trip. each van can carry 10 students how many vans are needed
klio [65]
First add how many kids total going on the field trip. 32+26=58
Each van carries 10 students so you can do 10+10+10+10+10=50+8 students left over. So you have 5 vans with 10 students in each plus 1 more van with 8 students so you would need 6 total vans. Hope this helps :)

20% of the children in a sports club play tennis.
padilas [110]

Answer:

160 children

Step-by-step explanation:

We can get this solution by working backwards in the equation.

First, we can treat the total number of strudents who play tennis as 't'. Giving us the equation: 8 = .25(t) . Solving this we get that there are 32 tennis players.

Next, we have to derive the total number of children in the sports club. Setting up 'x' as the total number of children, I get the equation 32 = .2(x) . Which leads us to the solution of 160 children in the sports club.
