What is the probability that 19 tosses of a fair coin will show 8 heads?

1 answer:

8 0

This can be solved by using the binomial distribution:
$P(8\ heads)=19C8\times(\frac{1}{2})^{8}\times(\frac{1}{2})^{11}=0.144$

Determine the x-intercept points of the function h(x) = (x - 5)(x-6)(x + 4).

AlexFokin [52]

Answer:

Step-by-step explanation:

The x-intercepts are the points where the x value is zero. In this case, to find the "zeros" of the function, set each factor to zero. x-5 -> x=5. x-6 -> x=6. x+4 -> x=-4.

I need to drink 8 2/4 cups of water and 2 1/5 cups milk every day. How much fluid do I have to drink?

lidiya [134]

Answer:

The total fluid you have to drink is 10 7/10 = 10.7 cups.

Step-by-step explanation:

The daily requirement of water = 8 2/4 cups

Now, $8 \frac{2}{4} = 8+ \frac{2}{4} = 8+ 0.5 = 8.5$

or, the daily water requirement = 8.5 cups

The daily requirement of milk = 2 1/5 cups

Now, $2 \frac{1}{5} = 2+ \frac{1}{5} = 2+ 0.2 = 2.2$

or, the daily milk requirement = 2.2 cups

So, The total fluid needed = Cups of (Water + Milk) needed

= 8.5 cups + 2.2 cups

= 10.7 cups

Also, $10.7 = 10 + 0.7 = 10 + \frac{7}{10} = 10\frac{7}{10}$

Hence, the total fluid you have to drink is 10 7/10 cups.

18 Given: the sequence 4, 7, 10, 13,...

Sergio039 [100]

a₁ = 4

n = 10

d = 3

a = a₁ + (n - 1)d

a₁₀ = 4 + (10 - 1)3

a₁₀ = 4 + (9)3

a₁₀ = 4 + 27

a₁₀ = 31

The 10th term would be 31 and the d variable will be replaced with the number 3.
