Each centimeter is three people so you just have to count the centimeter and multiply that by three to get the answer

Answer: For part A, Yakob has 9 friends that like Maths best, 6 friends that like History the best, & 15 friends that prefer <em>either</em> English or Science the best.

Part B: There's a graph I made below.

Step-by-step explanation:

You have to use proportions to answer this question. The bar graph is 10 cm total, therefore it is proportional to the 30 friends that Yakob has in total. After that, you can make proportions out of the data in the chart. For example, History is 2 cm out of the 10 cm total. Think proportions! You had to multiply 3 to 10 to get 30, so you have to apply the same thing to the numerator. In this case, multiply 3 to 2 and you'll get 6. 2/10=6/30! I repeated that for the rest and put it into a graph. The prompt wanted you to combine English and Science, so I did that after separately making their proportions. Hope this helps!

Find the probability of having 2, 3, or 4
denis-greek [22]

Answer:

16% for 2 successes, 6.4% for 3 successes, 2.6% for 4 successes, and 1% for 5 successes

Step-by-step explanation:

Since the success rate of a binomial experiment is 40%, converted to 0.4, you get the equation of f(x) = (0.4)^x, for where x is the amount of successful experiments

For the success of 2 experiments:

f(2) = (0.4)^2

     =0.16 => 16%

For the success of 3 experiments:

f(3) = (0.4)^3

     = 0.064 => 6.4%

For the success of 4 experiments:

f(4) = (0.4)^4

     = 0.0256 => 2.56% => ~2.6

For the success of 5 experiments:

f(5) = (0.4)^5

     = 0.01024 => 1.024% => ~1%

Your welcome and comment if you have any questions :)

Mrs. Lavetan has 45 to complete her writing paper. She spend 10 and 1/8 min to planning her paper and 15 and 1/2 minutes weighti
Flura [38]

Answer: 20 minutes

Step-by-step explanation:

She has 45 mins to complete her writing paper.

She spends: 10\frac{1}{8} minutes to plan her paper.

She spends: 15\frac{1}{2} minutes writing rough drafts.

How much time left does she have?

45-(10\frac{1}{8} +15\frac{1}{2})

45-(10+15(\frac{1}{8}+\frac{1}{2}))

45-(25\frac{(1)(2)+(8)(1)}{(8)(2)})

45-(25\frac{2+8}{16} )

45-(25\frac{10}{16}) Simplify the fraction.

45-(25\frac{5}{8})

45-25(\frac{5}{8})

So she has approximately,

20\frac{5}{8} =\frac{165}{8}= 20 minutes.
