Answer:

Total number of adult tickets sold = 10

Total Number of Students tickets sold = 30

Step-by-step explanation:

Let [tex]x[/tex] be the number of student tickets sold.

Let [tex]y[/tex] be the number of adult tickets sold.

As per the question statement, total tickets sold are 40.

[tex]x +y =40 ...... (1)[/tex]

Price of each student ticket = $5

Sales from students' tickets = Price of each students ticket [tex]\times[/tex] Number of students tickets sold

Sales from student's tickets = 5 [tex]\times x[/tex]

Price of each adult ticket = $9

Sales from adult's tickets = Price of each adult's ticket [tex]\times[/tex] Number of adult tickets sold

Sales from student's tickets = 9 [tex]\times y[/tex]

Total sales is done by students and adult tickets is $240 as per the question statement.

[tex]\Rightarrow 5x + 9y = 240 ......(2)[/tex]

Solving equations (1) and (2) using elimination method:

Equation [tex](2) - 5 \times (1)[/tex] :

[tex]5x + 9y -5x-5y = 240-200\\\Rightarrow 4y = 40\\\Rightarrow y =10[/tex]

Total number of adult tickets sold = 10

Putting [tex]y=10[/tex] in equation (1):

[tex]x+10 = 40\\\Rightarrow x = 30[/tex]

Total number of students tickets sold = 30

Total number of adult tickets sold = 10

Total Number of Students tickets sold = 30

Answer:

The distance Puis still have to travel to reach his destination is 72 km.

Step-by-step explanation:

The given parameters about Puis journey are

Distance covered by Puis = 1/4 of total distance

Distance remaining for Puis to complete the journey = 3/4 of the journey

Distance of Puis from the third-way (central) mark = 24 km

Therefore;

Distance from 1/4 of journey to 1/2 of journey = 24 km

Hence, 1/2 - 1/4 = 1/4 of the journey = 24 km

Which gives Total distance covered by Puis = 24 km

Total distance of the journey = 4 × 24 km = 96 km

The distance Puis still have to travel to reach his destination = 96 - 24 = 72 km.

Answer:

[tex](x+2.3)^{2} +y^{2} =36/49[/tex]

Step-by-step explanation:

To get the equation of a circle we plug your information into this equation:

[tex](x-h)^{2} +(y-k)^{2} =r^{2}[/tex]

Your h is the x coordinate of the center, -2.3 and your k is the y coordinate of the center, 0. The r is your radius. So we plug these values in to get [tex](x+2.3)^{2} +y^{2} =(6/7)^{2}[/tex] which then gives us the final answer of [tex](x+2.3)^{2} +y^{2} =36/49[/tex].

Answer:

Since M1 has the higher probability of being in the desired range, we choose M1.

Step-by-step explanation:

Problems of normally distributed samples are solved using the z-score formula.

In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

Two machines M1, M2 are used to manufacture resistors with a design specification of 1000 ohm with 10% tolerance.

So we need the machines to be within 1000 - 0.1*1000 = 900 ohms and 1000 + 0.1*1000 = 1100 ohms.

For each machine, we need to find the probabilty of the machine being in this range. We choose the one with the higher probability.

M1:

Resistors of M1 are found to follow normal distribution with mean 1050 ohm and standard deviation of 100 ohm. This means that [tex]\mu = 1050, \sigma = 100[/tex]

The probability is the pvalue of Z when X = 1100 subtracted by the pvalue of Z when X = 900. So

X = 1100

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{1100 - 1050}{100}[/tex]

[tex]Z = 0.5[/tex]

[tex]Z = 0.5[/tex] has a pvalue of 0.6915.

X = 900

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{900 - 1050}{100}[/tex]

[tex]Z = -1.5[/tex]

[tex]Z = -1.5[/tex] has a pvalue of 0.0668

0.6915 - 0.0668 = 0.6247.

M1 has a 62.47% probability of being in the desired range.

M2:

M2 are found to follow normal distribution with mean 1000 ohm and standard deviation of 120 ohm. This means that [tex]\mu = 1000, \sigma = 120[/tex]

X = 1100

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{1100 - 1000}{120}[/tex]

[tex]Z = 0.83[/tex]

[tex]Z = 0.83[/tex] has a pvalue of 0.7967.

X = 900

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{900 - 1000}{120}[/tex]

[tex]Z = -0.83[/tex]

[tex]Z = -0.83[/tex] has a pvalue of 0.2033

0.7967 - 0.2033 = 0.5934

M2 has a 59.34% probability of being in the desired range.

Since M1 has the higher probability of being in the desired range, we choose M1.

Step-by-step explanation:

One of the ways you can tell is that g(x) is always even. Only one table has that.

  g(x) = 2(x +2)

g(x) has a factor of 2 in every result, so cannot be odd for any integer x.

Answer:

 [tex]h=26.49m[/tex]

Step-by-step explanation:

First, take a look at the picture I attached you. It is a drawing which represent the problem.

As you can see from the picture the building height [tex]h[/tex] would be the sum of the person's height plus the length of the side [tex]a[/tex] of the triangle:

[tex]h=1,72m+a[/tex]

There are many ways to solve this problem, however I believe that the easiest one is using tangent identity which states:

[tex]tan(\theta) =\frac{opposite}{adjacent}[/tex]

Hence:

[tex]tan(54)=\frac{a}{18}[/tex]

Solving for [tex]a[/tex]:

[tex]a=tan(54)*18=24.77487457\approx24.77m[/tex]

So the building height is:

[tex]h=1.72+24.77=26.49487457\approx26.49m[/tex]

Translation:

Primero, mira la imagen que te adjunté. Es un dibujo que representa el problema.

Como puede ver en la imagen, la altura [tex]h[/tex] del edificio sería la suma de la altura de la persona más la longitud del lado [tex]a[/tex] del triángulo:

[tex]h=1,72m+a[/tex]

Hay muchas maneras de resolver este problema, sin embargo, creo que la más fácil es usar la identidad de la tangente que establece:

[tex]tan(\theta) =\frac{opuesto}{adyacente}[/tex]

Por lo tanto:

[tex]tan(54)=\frac{a}{18}[/tex]

Resolviendo para [tex]a[/tex]:

[tex]a=tan(54)*18=24.77487457\approx24.77m[/tex]

Entonces la altura del edificio es:

[tex]h=1.72+24.77=26.49487457\approx26.49m[/tex]

Step-by-step explanation:

This problem is related to binomial probability

Probability of getting head (success)p= 1/2

Probability of getting tail (failure )q=1/2

Total number of trials(n) = 8

number of success (r)= 3

Binomial probability P(r=3)

[tex]nCr(p)^{n-r}q^r[/tex]

Plug in the values in the formula

[tex]nCr(p)^{n-r}q^r\\8C3(\frac{1}{2} )^{8-3}\frac{1}{2} ^3\\ \frac{8!}{3!(8-3)!} (\frac{1}{2} )^8\\56 \cdot (\frac{1}{256} )\\0.21875[/tex]

To convert it into percentage , multiply by 100

0.21875 times 100= 21.9

Step-by-step explanation:

I’m not sure how technical they’re being with the last prompt but he would actually make 108 checkouts by clock out time. Sooo I’d say true, since he made more than inferred, rather than less.

Answer:

The first one is technically both because he will complete 18 every hour, not 16

The second one is false

Third one is true

and the fourth one is kind of like the first one where he will complete 108 in the span of 6 hours which is more than expected

Answer:

$2.96

Step-by-step explanation:

3x$2.67=$8.01

3x$2.73=$8.19

5x$3.27=$16.35

$8.01+$8.19+$16.35=$32.55

This makes 11 pounds of trail mix.

$32.55 divided by 11 = $2.9590909 = $2.96

Answer:

height = 9.19 ft

Step-by-step explanation:

The ladder is resting on a wall. The angle the ladder makes with the floor is 45°. The ladder is 13 ft. The illustration forms a right angle triangle.

The hypotenuse side of the right angle triangle is 13 ft . The opposite side of the right angle triangle is the unknown which is the height off the ground the top of the ladder. Therefore,

Using ratio

sin ∅ =  opposite/hypotenuse

sin ∅ = opp/13

sin 45° = opp/13

cross multiply

13 sin 45 = opp

opp = 13 × 0.70710678118

opp = 9.19238815543

height = 9.19 ft

You can use the following base on your equation(y = 13 cos ∅)

The other angle will definitely be 45° since total angle in a triangle is 180°. 180 - 90 - 45 = 45°.

The adjacent side of the triangle will be the unknown side if we use cosine ratio.

cos ∅ = adjacent/hypotenuse

cos 45° = adjacent/13

cross multiply

From your equation you represented adjacent as y therefore,

y = 13 cos 45°

y = 13 × 0.70710678118

y = 9.19238815543

y = 9.19 ft (which is the required height)

Answer:

Answer: We need we need 10 pints of the second fruit juice (85% pure fruit juice). Therefore, we need

(60-10 = 50) pints of the first fruit juice (55% pure fruit juice).

Step-by-step explanation:

Let x be number of pints of the first fruit drink which is ( 55% pure fruit juice), while y will be the number of pints of second fruit drink (85% pure fruit juice).

We know that there are 60 total pints. Therefore:

x + y = 60

We also know that 60% of the 60 pints will be pure fruit juice, and the pure fruit juice will either come from

x or y.

For x pints of first juice, there is 0.55x pure fruit juice while for y pints of first juice, there is 0.85y pure fruit juice. Therefore, we get:

0.55x + 0.85y = 60 × 0.6

0.55x + 0.85y = 36

We will get rid of the decimals by multiplying through by 100. This will be:

55x + 85y = 3600

Combining both equations

x + y = 60 .......... i

55x + 85y = 3600 ........ ii

Multiply equation i by 55

Multiply equation ii by 1

55x + 55y = 3300

- 55x + 85y = 3600

Then subtract

-30y = -300

y = 10

Therefore, we need we need 10 pints of the second fruit juice (85% pure fruit juice). Therefore, we need

(60-10 = 50) pints of the first fruit juice (55% pure fruit juice).
