Step-by-step explanation:

Here we are going to make the ski slope of the mountain as the hypotenuse of a right-angled triangle where the top of the slope and bottom of the slope are two ends of the hypotenuse.

We first have to find the height of the top of the mountain with respect to the bottom.

Here we have been given heights with respect to sea level above and below.

Clearly, sum of the distances above and below sea level will be total elevation with respect to the bottom.

h1 - Height of summit above sea level

h2 - Height of bottom below sea level

Hb - Elevation of top w.r.t bottom

Hb = h1 + h2

Hb = [tex]17\frac{3}{4}+13\frac{1}{4}[/tex]

Hb = 31 yards

Now, the ski lift is picking them up in the middle of the slope (hypotenuse of the triangle).

By midpoint theorem line segment parallel to base joins the midpoints of the other 2 sides.

Thus the elevation will clearly be half of total elevation.

Height at which they are picked up is Hb/2

Therefore,

They will be picked up at an elevation of 15.5 yards

Answer:

120 calories and 9 grams of fiber.

Step-by-step explanation:

We are told that 1/3 cup serving contains 80 calories and 6 grams of fiber.

Let's multiply everything by 3. So,

1 cup serving has 3*80 = 240 calories and 3*6 = 18 grams of fiber.  

But, we want to really know about 1/2 cup. So, now we multiply everything by 1/2.  

1/2 cup has (1/2) (240) = 40 calories and (1/2) (18 grams) = 9 grams of fiber.

Solution:

Let  the time taken by one machine to fill a certain production alone be[tex]=\text{x}[/tex]

Time taken when three machine operate independently and simultaneously

[tex]\frac{1}{\text{x}}+\frac{1}{\text{x}}+\frac{1}{\text{x}}=\frac{1}{36}[/tex]

Let time taken when one additional machine is used [tex]=\text{y}[/tex]

Time when when one additional machine is used

[tex]\frac{1}{108}+\frac{1}{108}+\frac{1}{108}+\frac{1}{108}=\frac{1}{\text{y}}[/tex]

[tex]\frac{4}{108}=\frac{1}{\text{y}}[/tex]

[tex]\text{y}=27[/tex] [tex]\text{hours}[/tex]

it takes [tex]27[/tex] [tex]\text{hours}[/tex] when one additional machine is used

Now,

fewer hours taken when one additional  machine is used

[tex]=\text{number of hours taken when three machines are used}-[/tex][tex]\text{number of hours taken when one additional machine is used}[/tex]

[tex]36-27[/tex]

Answer:

The answer to your question is Stacy multiplies the second equation by 4.

Step-by-step explanation:

                                             24x - 39y = 165    (I)

                                             - 6x + 13y = -51     (II)

Multiply the second equation by 4

                                             24x -    39 y = 165

                                           -24x  +   52y  = -204  

Simplify

                                              0    +  13y = 39

                                                           y = 39/ 13

                                                           y = 3

Find "x" value                       24x - 39(3) = 165

                                             24x - 117 = 165

                                             24x = 165 + 117

                                             24x = 282

                                                 x = 282 / 24

                                                 x = 47/4

Therefore, cube has congruent squares on all six sides.

Answer:

0.0421

Step-by-step explanation:

Mean(μ) = 12.00 oz

Standard deviation (σ) = 0.11 oz

Z = (x - μ)/σ

Z = (12.19 - 12.00) / 0.11

Z= 0.19/0.11

Z = 1.727

From the normal distribution table, Z = 1.727 = 0.4579

Φ(Z) = 0.4579

Recall that if Z is positive

Pr(x>a) = 0.5 - Φ(Z)

Pr(x > 12.19) = 0.5 - 0.4579

Answer:

Step-by-step explanation:

There are at least a couple of ways you could go at this. Here, we'll use an area formula to find m∠A, then use the law of cosines to find BC. Using BC, we can use the law of sines to find another angle.

  Area = (1/2)·AB·AC·sin(∠A)

  65·2/(12·17) = sin(∠A) ≈ 65/102

  ∠A = arccos(65/102) ≈ 39.587°

From the law of cosines, ...

  BC² = AB² +AC² -2·AB·AC·cos(∠A)

  BC² = 12² +17² -2·12·17·cos(39.587°) ≈ 118.5735

  BC ≈ √118.5735 ≈ 10.889

Then ∠C can be found from the law of sines:

  sin(∠C)/AB = sin(∠A)/BC

  ∠C = arcsin(AB/BC·sin(∠A)) ≈ 44.609°

The measure of ∠B will be the angle that makes the total be 180°:

  39.587° +∠B +44.609° = 180°

  ∠B = 95.804°

_____

There is actually another solution, in which ∠A is obtuse. We thought the diagram showed an acute triangle, so we didn't investigate the other alternative. The above calculations show the triangle is obtuse in any event.

Suppose you drive a car 392 miles on one tank of gas. The tank holds 14 gallons of gas. This means that

1 gallon of gas would be used to drive 392/14 = 28 miles

a) The number of miles traveled varies directly with the number of gallons of gas used.

Let x =number of gallons of gas you use.

Let y = the number of miles travelled.

Since y varies directly with x, we will introduce a constant of proportionality, k. Therefore,

y = kx

If 28 miles will require 1 gallon of gas, it means

28 = 1×k

k = 28

So y = 28x

b) we want to determine how far you can drive with 3.7 gallons of gas.

x = 3.7

y = 28x = 28×3.7

y = 103.6 miles

Step-by-step explanation:

Since, Function of demand is the linear function of quantity.

Let x represents the quantity and p represents the price of each unit.

∵ Manufacture has been selling 1450 television sets a week at $540 each,

i.e. [tex](x_1, p_1) = (1450, 540)[/tex]

Also, for each $13 rebate offered to a buyer, the number of sets sold will increase by 130 per week.

i.e. [tex](x_2, p_2) = (1580, 527)[/tex]

Thus, the linear equation of the price,

[tex]p-p_1 = \frac{p_2-p_1}{x_2-x_1}(x-x_1)[/tex]

[tex]p-540 = \frac{527 - 540}{1580-1450}(x-1450)[/tex]

[tex]p-540 = -\frac{13}{130}(x-1450)[/tex]

[tex]p-540 = -\frac{1}{10}(x-1450)[/tex]

[tex]p = -\frac{1}{10}x + 145 + 540[/tex]

[tex]\implies p = -\frac{1}{10}x + 685[/tex]

Hence, the function representing price as a function of the demand is,

[tex]p(x)= -\frac{1}{10}x + 685[/tex]

To find the probability of both Alex and Bob winning at least 2 games during their 5 games chess play, principles of geometric probability and the Multiplication rule are used. The equation _(p^2)*(5 choose 2)*((p/3)^2)*(5 choose 2)*[(p+(p/3))] is formed considering Alex is 3 times more likely to win than Bob.

Calculating Probability of Games

In this scenario, Alex and Bob are playing 5 games with Alex being 3 times more likely to win than Bob. The primary question is to find the probability for both of them winning at least 2 games.

We would utilize the principles of geometric probability to solve this. Geometric probability treats each game as a Bernoulli trial, a game of win or lose. Moreover, we operate with the Multiplication rule in finding the probability of both events, Alex and Bob winning 2 games, happening.

Firstly, we define the probability of Alex winning as p, therefore, the probability of Bob winning is p/3. Bob and Alex must win 2 games each, leaving one game open to any outcome. Since the games are independent, the Multiplication rule applies. Therefore, the probability is calculated by multiplying probabilities for each win and possible combinations of five games taken two at a time. In other words, the equation will look like  _(p^2)*(5 choose 2)*((p/3)^2)*(5 choose 2)*[(p+(p/3))].

The resulting value will be the probability for both of them winning at least 2 games.

test statistic (Z) is 2.5767 and p-value of the test is .009975

Step-by-step explanation:

[tex]H_{0}[/tex]: percentage of students who smoke did not change

[tex]H_{a}[/tex]: percentage of students who smoke has changed

z-statistic for the sample proportion can be calculated as follows:

z=[tex]\frac{p(s)-p}{\sqrt{\frac{p*(1-p)}{N} } }[/tex] where

Then, z=[tex]\frac{0.25-0.18}{\sqrt{\frac{0.18*0.82}{200} } }[/tex] ≈ 2.5767

What is being surveyed is if the percentage of students who smoke has changed over the last five years, therefore we need to seek two tailed p-value, which is .009975.

This p value is significant at 99% confidence level. Since .009975 <α/2=0.005, there is significant evidence that the percentage of students who smoke has changed over the last five years

Answer:

the answer is 17.7

Step-by-step explanation:

Apply tanθ =  

opposite

adjacent

tanθ =  

7

22

θ = tan−1(

7

22

)

θ = 17.7°

The angle the ladder that will make with the wall is 17.7°.

What is tangent of an angle?

Tangent of the angle is the ratio between the opposite side and adjacent side of the angle in the right angle triangle.

So according to the asked question,

the distance between lader foot and the wall  is 7feet.

the height of the wall is 22feet.

So in triangle ΔABC ,

the height of the wall =AB=22feet

the distance between lader foot and the wall=BC=7feet

∠ABC=90°

the angle between the ladder and the wall= ∠BAC=θ

So in ΔABC,

tan ∠BAC=tan θ=BC/AB

⇒tan θ=7/22

⇒θ=tan⁻¹(7/22)

⇒θ=17.7⁰

Therefore the angle the ladder that will make with the wall is 17.7°.
