Paul has 16 baseballs and 12 golf balls what is the ratio of balls to golf balls

1 answer:

5 0

Ratio is just a fraction in other form. To create ratio we can just make fraction and transform it into ratio, so
$\frac{baseballs}{golf bals} = \frac{16}{12} =16:12$
Now we can simplify the ratio/fraction
$\frac{16}{12} = \frac{4}{3}$ = 4:3 - its the result

If f(x)=5x^2-3 and g(x)=x^2-4x-8, find (f-g)(x)

PSYCHO15rus [73]

Answer:

4x^2 + 4x + 3.

Step-by-step explanation:

(f - g)(x)

= f(x) - g(x)

= 5x^2 - 3 - (x^2 - 4x - 6)

= 5x^2 - 3 - x^2 + 4x + 6

= 4x^2 + 4x + 3.

Color-blindness is any abnormality of the color vision system that causes a person to see colors differently than most people or

Veronika [31]

Answer:

Correct option is (d): Neither X nor Y can be well-approximated by a normal random variable.

Step-by-step explanation:

The sample size of males having color-blindness is, n (X) = 20.

The sample size of females having color-blindness is, n (Y) = 40.

The proportion of males that suffer from color-blindness is, P (X) = 0.08.

The proportion of females that suffer from color-blindness is, P (Y) = 0.01.

Now both the random variables X and Y follows a Binomial distribution,

$X\sim Bin(20, 0.08)\\Y\sim Bin(40, 0.01)$

A normal distribution is used to approximate the binomial distribution if the sample is large, i.e n ≥ 30 and the probability of success is very close to 0.50.

Also if np ≥ 10 and n (1 - p) ≥ 10, the binomial distribution can be approximated by the normal distribution.

For the sample of men (X):

$np=20\times0.08=1.610$

In this case neither n > 30 nor p is close to 0.50.

And np < 10.

Thus, the random variable X cannot be approximated by the normal distribution.

For the sample of men (Y):

$np=40\times0.01=0.410$

In this case n > 30 but p is not close to 0.50.

And np < 10.

Thus, the random variable Y cannot be approximated by the normal distribution.

Thus, both the random variables cannot be approximated by the normal distribution.

The correct option is (d).
