SAM now has 30ml of pop to share equally into glasses.

crimeas [40]

So whole ml's

30 mls
find what 30 is evenly divisble by
factor 30
30=2 times 3 times 5
therefor
30 is divisble by 2,3,5,6,10,15

so he can divide the glass into 2 sevings which is 30/2=15 ml in each

servings ml    fraction
2 15 15/30=1/2
3 10 10/30=1/3
5 6    6/30=1/5
6 5 5/30=1/6
10    3 3/30=1/10
15 2 2/30=1/15

A test consists of 10 true/false questions. To pass the test a student must answer at least 88 questions correctly. If a student

Zanzabum

Answer:

The probability that the student is going to pass the test is 0.0545

Step-by-step explanation:

The variable that says the number of correct questions follows a Binomial distribution, because there are n identical and independent events with a probability p of success and a probability 1-p of fail. So, the probability of get x questions correct is:

$P(x)=\frac{n!}{x!(n-x)!} *p^{x} *(1-p)^{n-x}$

Where n is equal to 10 questions and p is the probability of get a correct answers, so p is equal to 1/2

Then, if the student pass the test with at least 8 questions correct, the probability P of that is:

P = P(8) + P(9) + P(10)

$P=(\frac{10!}{8!(10-8)!}*0.5^{8}*(0.5)^{10-8})+(\frac{10!}{9!(10-9)!} *0.5^{9} *(0.5)^{10-9})+(\frac{10!}{10!(10-10)!} *0.5^{10} *(0.5)^{10-10})$

P = 0.0439 + 0.0097 + 0.0009

P = 0.0545

Write the sum as a product of two factors.

Elena-2011 [213]

A) 81 and 48 have a common factor of 3:
81w+48= 3(27w+16)

b) 10 and 25 have a common factor of 5:
10-25t=5(2-5t)

c) 12, 16 and 8 have common factors of 4:
12a+16b+8=4(3a+4b+2)

Hope this helps :)

Parallelogram Property: opposite angles are congruent<br><br> Solve for x

Anna11 [10]

Answer:

Step-by-step explanation:

Equate the two opposite Angles

7x - 31 = 5x + 13 Subtract 5x from both sides

7x - 5x - 31 = 13 Combine

2x - 31 = 13 Add 31 to both sides

2x = 13 + 31 Combine the right

2x = 44 Divide by 2

x = 44/2

x = 22
