Answer:

The answer is option 2.

Step-by-step explanation:

You have to apply Cosine Rule, cosθ = adjacent/hypotenuse. Then, you have to substitute the values into the formula :

cos(θ) =  \frac{adj.}{hypo.}

let \: θ = 55

let \: adj. = 11

let \: hypo. = x

cos(55) =  \frac{11}{x}

Answer:

cos(55) = 11/x

Step-by-step explanation:

We have the hypotenuse (x) and an angle adjacent to 55 (11). The only trigonometric formula that uses adjacent and hypotenuse is cosine (adjacent/hypotenuse), so that will be your answer.

A freezer has a volume of 54 ft.³ it has a length of 6 feet and a height of 3 feet what is the length of the width of the freeze
gogolik [260]
Ok so let’s see we have L and H but we don’t have the W so to find it we start by multiplying the numbers we do have which is L and H so 6x3=18 know that we did that we tasked the volume number which is 54 and we divide that by 18 so 54➗18 = 3 so our width is 3

Hope this helped :)

roger average 3 hits for every 12 times he is at bat at his. rate how many must he bat to hit 12 hits
Reptile [31]
He can hit 3 out of every 12 bats. This can be translated to 3/12. We want to make the numerator 12, so we multiple the top by 4, so we have to do the same thing on the bottom. This fraction would be 12/48.

He has to bat 48.

a ball is tossed into the air at 20 feet per second from a height of 7 feet. How long will it take the ball to reach the​ ground
nirvana33 [79]

We have been given that the ball is tossed into air at a speed of 20 feet per second and from a height of 7 feet.

We are supposed to use the formula:

s(t)=-16t^{2}+v_{0}t+s_{0}

Upon substituting the given values of initial velocity and initial altitude, we get:

s(t)=-16t^{2}+20t+7

We need to figure out the time that will take the ball to reach the ground. In order to do so, we will substitute s(t)=0 and solve for t.

-16t^{2}+20t+7=0\\

Upon using quadratic formula, we get:

t=\frac{-20\pm \sqrt{20^2-4\left(-16\right)7}}{2\left(-16\right)}\\t=\frac{5\pm\sqrt{53}}{8}\\

Upon finding the values of t using calculator, we get t=-0.285, 1.535

Therefore it will take the ball approximately 1.54 seconds to hit the ground.

Aaliyah wants to determine how age and gender are related to movie genre preference in her town. She selects a simple random sam
-Dominant- [34]

Answer:

The correct option is;

E. She will not be able to tell whether a difference in movie genre preference is related to a difference in age or to a difference in gender

Step-by-step explanation:

The question states that Aaliyah randomly selects the following;

First sample

Sample gender = Males

Sample size = 35

Age bracket of sample = 20 to 30 years

Second sample

Sample gender = Females

Sample size = 45

Age bracket of sample = 45 to 55 years

The plan is to determine how age and gender are related to movie genre preference

Appropriate sample distribution to determine movie genre preference is as follows;

Gender = Male

Age bracket = 20 to 55 years

Gender = Female

Age bracket = 20 to 55 years

Therefore, since the samples selected do not cut across the population of the by age and gender of movie genre preference, she will not be able to tell whether a difference in movie genre preference is related to a difference in age or to a difference in gender.
