in 1900, half of the babies born in America were born with blue eyes. Which simulation could be used to find the probability that 3 out of 4 babies born had blue eyes? A.) Toss a coin two times B.) Spin a spinner with 4 equal sections two times C.) Roll a six sided number cube two timesD.) Picks a card from 10 cards two times.

Answer:

B.) Spin a spinner with 4 equal sections two times

Step-by-step explanation:

Given that half of the babies born were blue eyes, then the probability of a baby born with blue eye is 50% = 0.5

The probability that 3 out of 4 babies born had blue eyes will be;

0.5*0.5*0.5*0.5=0.0625

This case is similar to the probability of a Spin, a spinner with 4 equal sections spinned two times;

The probability of the spinner in one spin is 1/4 =0.25

If the process is done twice, the probability is : 0.25*0.25 =0.0625

This case is similar to the scenario in question.

1.5r - 3r + 8r + 2.5r solve by combining like terms

The simplified form of the given expression is 9r.

The given expression is 1.5r - 3r + 8r + 2.5r.

We need to solve the given expression.

What is like terms in an expression?In Algebra, the like terms are defined as the terms that contain the same variable which is raised to the same power. In algebraic like terms, only the numerical coefficients can vary. We can combine the like terms to simplify the algebraic expressions so that the result of the expression can be obtained very easily.

Now 1.5r - 3r + 8r + 2.5r

=1.5r+2.5r- 3r + 8r

=4r+5r

=9r

Therefore, the simplified form of the given expression is 9r.

Answer is 63

Hope this helps.

Hope this helps.

Answer:

-63

Step-by-step explanation:

9(-11 - -4)

First you would use PEMDAS

Parenthesis go first so (-11 - -4) and that is -7

The next step is multiplication so you would multiply 9*-7

And that equals -63
