What is the length, in meters, of the ramp, line segment AC, below? Round to the nearest whole number if necessary.

Brrunno [24]

10 meters.

Step-by-step explanation:

To find the missing side of a right triangle, we can use the Pythagorean theorem.

The Pythagorean theorem is...

$a^2+b^2=c^2$

Please be sure to note that a and b will always be the length of the sides and c will always be the hypotenuse, or in this case the ramp.

Since we know the values of both of the sides we can plug this into the theorem.

$6^2+8^2=c^2$

Now we can solve.

$36+64+c^2$

Add.

$100=c^2$

Many people will make the mistake of thinking 100 is the final answer, but since c is squared we need to find the square root of 100.

$\sqrt{100} =10$

c = 10

The ramp is 10 meters.

A cohort study was conducted to study the association of coffee drinking and anxiety in a population-based sample of adults. Amo

Answer: Relative risk of anxiety associated with coffee use is 5 times the anxiety associated with non coffee use.

Step-by-step explanation:

Since we have given that

Number of coffee drinkers = 10000

Number of whom developed anxiety = 500

Number of non coffee drinkers = 20000

Number of whom developed anxiety = 200

So, probability of getting anxiety from coffee drinkers = $\dfrac{500}{10000}=0.05$

Probability of getting anxiety from non coffee drinkers = $\dfrac{200}{20000}=0.01$

so, Relative risk of anxiety associated with coffee use is given by

$\dfrac{0.05}{0.01}=5$

Hence, Relative risk of anxiety associated with coffee use is 5 times the anxiety associated with non coffee use.

Please can anyone help me on this question information below.

Delvig [45]

Answer:

a) 0.11

b) 60

Step-by-step explanation:

Total frequency:

12+35+11+23+7+12 = 100

P(3) = 11/100 = 0.11

P(6) = 12/100 = 0.12

Expected no. of sixes:

500 × 0.12 = 60

What is the equation of the line that is parallel to the given line and passes through the point (−4,−6 )?

riadik2000 [5.3K]

The question says that the line is parallel to the line above, so it is horizontal. When the line is horizontal it will be a 'Y=' Then, you take a look at the y axis and check to see what part of the axis the line is going through. Therefore, you can figure out that the awnser is C. I hope this explanation helps!
