Answer:

6/8.

Step-by-step explanation:

the cool part about fractions is that you can convert fractions to decimals using so many tools out there.

first, you could want to convert 3/5 into a decimal. 3/5=0.6.

second, convert 6/8 into a decimal. 6/8=0.75.

now, it should be easier to compare. therefore, 6/8 is greater than 3/5.

here's a helpful tool if you want to convert fractions to decimals;

The probability that a lab specimen contains high levels of contamination is 0.10. A group of 4 independent samples are checked.

galben [10]

Answer:

a) 0.6561

b) 0.2916

c) 0.3439

Step-by-step explanation:

We are given the following information:

Let us treat high level of contamination as our success.

p = P(High level of contamination) = P(success) = 0.10

n = 4

The, by binomial distribution:

$P(X=x) = \binom{n}{x}.p^x.(1-p)^{n-x}\\\text{where x is the number of success}$

a) P(No high level of contamination)

We put x = 0, in the formula.

$P(X=0) = \binom{4}{0}.(0.10)^0.(1-0.10)^{4} =0.6561$

Probability that no lab specimen contain high level of contamination is 0.6561

b) P(Exactly one high level of contamination)

We put x = 1, in the formula.

$P(X=1) = \binom{4}{1}.(0.10)^1.(1-0.10)^{3} =0.2916$

Probability that no lab specimen contain high level of contamination is 0.6561

c) P(At least one contains high level of contamination)

$p(x \geq 1) = 1 - p( x = 0) = 1 - 0.6561 = 0.3439$

Probability that at least 1 lab specimen contain high level of contamination is 0.3439

Can somebody please help me

guajiro [1.7K]

Here is your answer

B. (12,30)

REASON:

Given,

$y= 2x+6$ .......(i)

$3x-y= 6$ .......(ii)

Putting the value of y from eq.i in eq.ii we get

$3x-(2x+6)=6$

$3x-2x-6=6$

$=6+6$

$x=12$

Putting x=12 in eq.i we get

$y= 2x+6$

$y= 2×12+6$

$y= 24+6$

$y= 30$

So,

$\bold{x=12 and y= 30}$

Hence answer is (12,30) in which x=12 and y=30

Use these properties to rewrite 7/4 + 1/2 + 5/3 + 1/3 + 1/4 + 1/2 in a way that makes the addition easier. Explain how your chan

Reptile [31]

It makes the addition easier if you combine like terms like the two 1/2s and then make them all have the denominator of 12 (changing the numerators to equal it out)

A line passes through the point (-8, 6) and has a slope of 3/2

Vladimir79 [104]

Answer:

y-6=3/2(x+8)

Step-by-step explanation:

so the point slope form is y-y₁=m(x-x₁)

so enter the points (-8, 6)

y-6= 3/2(x-(-8))

y-6=3/2(x+8)
