Mathematics

Lina20 [59]3 years ago

Answer:

Step-by-step explanation:

ahh that's like a math tongue twister  :P

so just remember that when you are given the final amount, as the 0.99 is,  then you want to divide by the total, like this

0.99 / 9.90 =  

we don't really need a calculator for this,  b/c you can see that the answer will come out to a one,  but, where is the decimal, huh

my calculator put the decimal here  0.1

so that's 10% right?  which totally makes sense.. right?    0.99 is 10% of 9.90... just move the decimal one place in the 9.9 to get  .99  see?  so that kinda helps us know where the decimal goes in the answer, if that make sense? The decimal gets moved one place to the  LEFT  of the one, in our answer when we just did the math in our head.

anyway.. leave a comment if you have more questions :)

Answer:

10%

Step-by-step explanation:

first let's write out the problem

0.99 is what percent of 9.90     =        0.99=9.90*x

We need to   what c is so we would do the opposite operation of multiplication, division so we get,

0.99/9.90= .1

now we turn .1 into  percent and get out answer

0.1= 10%

Suppose that the probability that a child living in an urban area in the United States is obese is 20%. If a social worker sees
Levart [38]

Answer:

The probability the event that none of them are obese is 0.0352.

Step-by-step explanation:

<h3>Binomial distribution:</h3>

A discrete random variable X having to the set {0,1,2,3....,n} as the spectrum, is said to have binomial distribution with parameters n= the number of trial, and p= probability of successes on an individual trial , if the p.m.f of X is given by,

P(X=x)=\left(\begin{array}{c}n\\x\end{array}\right) p^x(1-p)^{n-x} for x=0,1,2,...,n

                =0                               elsewhere.

where 0<p<1 and  n an positive integer,

Given that,

The probability of the event that a child living in an urban area in the united state is obese is 20%.

n=Number of children = 15, p= 20%= 0.20.

The probability the event that none of them are obese is

=P(X=0)

=\left(\begin{array}{c}15\\0\end{array}\right) (0.20)^0(1-0.20)^{15-0}

=0.0352

Please help i will mark brainlist
Feliz [49]

Answer:

72.22 inches

Step-by-step explanation:

Okay so the formula for circumference is C=2πr so since the diameter is twice the radius, the radius is 11.5. Now you have to multiply 11.5 and 2. That equals 23. Now you have to multiply 23 by π which is about 3.14. 23 times 3.14 is 72.22 inches.

Hope this helped!! :D

Step-by-step explanation:

At the top of the Ferris wheel,the ride is 1/2 done. All that is left is to go down,which is the other half. Maria is wrong in saying they are 1/4 done,that is a quarter,not half.

Two fractions have a common denominator of 8 which of these could be two fractions 1/2 and 2/3 and 1/4 1/2
Anna007 [38]
Hi

Fractions that have a common denominator of 8, would be fractions that have denominators that, when multiplied, equal 8. 

8/2 = 4
8/3 = 2.7
So the first option is incorrect.

8/4 = 2
8/2 = 4
The second option is correct.

The correct answer is 1/4 and 1/2

Hope this helps! :)
