A survey of teens suggested that 33% can name at least one professional baseball player, and 90% of those teens can also name at

loris [4]

Answer:

$d.\ 0.33 + 0.64 – (0.90)(0.33) = 0.673$

Step-by-step explanation:

Given

$P(Baseball) = 33\%$

$P(Baseball\ n\ Football) = 90\%$

$P(Football) = 64\%$

Required

$P(Baseball\ or\ Football)$

This is calculated as:

$P(Baseball\ or\ Football) =P(Baseball) + P(Football) -P(Baseball\ n\ Football)$

$P(Baseball\ or\ Football) = 0.33 + 0.64 - (0.90)(0.33)$

$P(Baseball\ or\ Football) = 0.33 + 0.64 - 0.297$

$P(Baseball\ or\ Football) = 0.673$

For a binomial process, the probability of success is 40 percent and the number of trials is 5. Find the variance.

Natalka [10]

Answer:

1.2

Step-by-step explanation:

The variance of a binomial distribution is:

σ² = n p (1 − p)

where n is the number of trials and p is the probability of success.

Given n = 5 and p = 0.40:

σ² = 5 (0.40) (1 − 0.40)

σ² = 1.2

On a piece of paper, use a protractor and a ruler to construct two equilateral triangles: one with a side length of 4 inches and

sergiy2304 [10]

Answer:

the two triangles are the same shape but not the same size

Step-by-step explanation:

an equilateral triangle has all equal sides. if one triangle has a side length of 4 inches, it'll be smaller than the triangle with the side length of 5 inches but just because they're different sizes doesn't mean they're a different shape. (i don't know if this is right but I'm pretty sure it is)

The ratio of men to women in a certain factory is 3 to 4. There are 210 men.

WARRIOR [948]

There are 490 workers

3/4 = 210/x
Cross multiply, 210x4 and 3x
You're then left with 3x = 840, divide both sides by 3
This answer is 280 and represents the amount of female workers

Then just add 210 and 280, your answer is 490. Hope that helps!
