HELP PLEASE??!!! AHAHHA

What is the value of x? O 6 O 62 O 12 O 122

Taya2010 [7]

Answer:

Step-by-step explanation:

12

This is what we call a 45-45 traingle

This means that the lengths of the two non-hyptonouse lengths are the same

luckily we're given that it's 6√2

We can then use the pathagaryem theory to solve for the last side

we have

(6√2)²+(6√2)²=x²

Put this into your calculator and get

144= x²

x = 12

bagirrra123 [75]

Answer:

Probability that at least one of them suffers from arachnophobia is 0.5160.

Step-by-step explanation:

We are given that a 2005 survey found that 7% of teenagers (ages 13 to 17) suffer from an extreme fear of spiders (arachnophobia).

Also, At a summer camp there are 10 teenagers sleeping in each tent.

Firstly, the binomial probability is given by;

$P(X=r) =\binom{n}{r}p^{r}(1-p)^{n-r} for x = 0,1,2,3,....$

where, n = number of trials(teenagers) taken = 10

r = number of successes = at least one

p = probability of success and success in our question is % of

the teenagers suffering from arachnophobia, i.e. 7%.

Let X = Number of teenagers suffering from arachnophobia

So, X ~ $Binom(n= 10,p=0.07)$

So, probability that at least one of them suffers from arachnophobia

= P(X >= 1) = 1 - probability that none of them suffers from arachnophobia

= 1 - P(X = 0) = 1 - $\binom{10}{0}0.07^{0}(1-0.07)^{10-0}$

= 1 - (1 * 1 * $0.93^{10}$ ) = 1 - 0.484 = 0.5160 .

Therefore, Probability that at least one of them suffers from arachnophobia is 0.5160 .

A child is 12 years old, and his father is 32 years older. In how many years will the age of the father be 2 times the age of th

notsponge [240]

Hello :)

In 8 years, the father will be 2 times older than the child.

In 8 years, the father will be 40

In 8 years, the child will be 20

40 ÷ 20 = 2

So again, the answer is 8 years :)

Hope this helps and have a great day

There are 10 friends who are trying to play and beat the video game, Breath of the Wild. There are 76 side quests in this game.

Answer:

2; 28.5 ; 34 ; 36 ; 38

Step-by-step explanation:

Given the data:

X = 25, 28, 29, 30, 34, 35, 35, 37, 38

n = 9

Values have been arranged in ascending order ;

The 5 number summary :

Maximum value : highest data value in the list = 38

Minimum value : Lowest data value in the list = 25

The lower quartile ; Q1 = 1/4(n+1)th term

Q1 = 1/4(10) th term = 2.5th term

Q1 = (2nd + 3rd) / 2 = (28+29)/2 = 28.5

Q2 = 1/2(n+1)th term

Q2 = 1/2(10) th term = 5th term

Q2 = 34

Q3 = 3/4(n+1)th term

Q3 = 3/4(10) th term = 7.5th term

Q3 = (7th + 8th) / 2 = (35+37)/2 = 36

Maximum value = 38 (highest data value in the list)
