=========================================

Explanation:

x = number of people

Without the discount, each person pays $72, so the total cost is 72x dollars if x people go through the gate individually.

Now applying the group discount, those x people pay 72-25 = 47 dollars each. Meaning the total cost is now 47x. Keep in mind that [tex]x \ge 15[/tex] in order for the discount to kick in.

Subtracting the two amounts leads to 72x-47x = 25x. It is not a coincidence that we get a coefficient of 25 here.

Set this equal to 500 and solve for x

25x = 500

x = 500/25

x = 20

------------

If x = 20 people attend individually, then they pay 72*x = 72*20 = 1440 dollars.

If 20 people go as one group, they pay 47x = 47*20 = 940 dollars

We have a savings of 1440-940 = 500 dollars. This confirms the answer.

All 20 people must go as one group if they want to save $500.

Answer:

17:420

Step-by-step explanation:

17 seconds : 7 minutes

7 minutes = 420 seconds

17:420

The ratio of time measurements in two different units is 1/30.

Ratio is the quantitative relation between two amounts showing the number of times one value contains or is contained within the other.

Given are the time measurements in two different units.

Converting 2 minutes into seconds -

2 min = 2 x 60 = 120 seconds

Now, 4 seconds to 120 seconds can be written as fraction below -

x/y = 4/120 = 1/30

Then, the ratio will be -

x : y = 1 : 30

Therefore, the ratio of time measurements in two different units is 1:30

Answer:

81/100

Step-by-step explanation:

Answer:

A) Null Hypothesis: H0: μ ≤ 14

Alternative hypothesis: Ha: μ > 14

B) If the null hypothesis H0 is not rejected, it means that there is no sufficient evidence to support the claim that new bonus plan increases

sales volume.

C) If the null hypothesis is rejected, it means there is sufficient evidence to support the claim that the new bonus plan increases sales volume

Step-by-step explanation:

A) We are told that the mean sales volume is 14 automobiles per month.

The hypotheses is defined as follows;

Null Hypothesis: H0: μ ≤ 14

Alternative hypothesis: Ha: μ > 14

B) If the null hypothesis H0 is not rejected, it means that there is no sufficient evidence to support the claim that new bonus plan increases

sales volume.

C) If the null hypothesis is rejected, it means there is sufficient evidence to support the claim that the new bonus plan increases sales volume.

Answer:

16.8  or 17 blue

50.4  or 50 brown

33.6  or 34 yellow

33.6  or 34 red

16.8  or 17 orange

16.8  or 17 green

Step-by-step explanation:

7 x 24 = 168 candies

blue = b

brown = w

yellow = y

red = r

orange = o

green = g

1b = 3w + 2y + 2r + 1o + 1g

1 +3 + 2 + 2 + 1 + 1 = 10

168/10 = 16.8

1(16.8) +3(16.8) + 2(16.8) + 2(16.8) + 1(16.8) + 1(16.8) =

16.8 blue

50.4 brown

b) y= ¼x +1

Step-by-step explanation:

Please see the attached picture for the full solution.

Further explanation:

b) y-intercept of A= 5

y-intercept of line= 5 -4= 1

Since the gradient of the line is equal to the gradient of line A, gradient of line= ¼.

Answer:

About 25 sandwiches...

Step-by-step explanation:

Answer:

67 sandwiches

Step-by-step explanation:

If you invest 250 dollars to start, you're currently -250. If you gain 5.25 per sandwich you sell, you'd need to sell about 67 sandwiches.

I'm not entirely sure what your question meant though. If the question is simply asking how many sandwiches it would take to make 100 dollars, it would be about 20 sandwiches. If the question is asking how many sandwiches you'd need to sell to gain 100 dollars in profit, covering the cost of the cart, it would be about 67 sandwiches.

Answer:

NO.

Step-by-step explanation:

The Professor's hypothesis:

An introductory course in Logic will affect college students with their other studies (will affect their Great Point Average - GPA).

25 students are used as the experimental group while the rest of the class are the control group.

The mean GPA in a sample size (SS) of 6 is = 2.58

The mean GPA in the full sample size of 25 would be = 10.75 by crossmultiplying.

This makes me believe the question was written wrongly. I assume SD (standard deviation) of 0.6 instead of SS (sample size) of 6.

Going by this, if standard deviation is 0.6 then the interval within which the GPA of the experimental group (the 25 students) falls is:

[2.58 - 0.6] to [2.58 + 0.6]

= 1.98 to 3.18

The rest of the graduating class (the control group) had a mean GPA of 2.33

Can the professor conclude that the GPA for the sample is significantly different from that of the control group?

The answer is NO because the GPA of the control group falls within the GPA interval of the experimental group!

Answer:

  -73 3/10

Step-by-step explanation:

Pronouncing a decimal number can help when you convert it to a mixed number. This one is ...

  "negative seventy-three and three tenths"

Of course, expressing "three tenths" as a fraction, you have 3/10.

Then your number is ...

  -73.3 = -73 3/10

Answer:

37.3 x 10⁶

Step-by-step explanation:

Given parameters:

Number of people in California = 3.9 x 10⁷

Number of people in Idaho = 1.7 x 10⁶

Unknown:

How many more people live in California than live in Idaho = ?

Solution:

To find the number of people living in California more than Idaho, simply find the differences between the number of their population;

     =   3.9 x 10⁷  - 1.7 x 10⁶

    = 39 x 10⁶ - 1.7 x 10⁶

    = (39 - 1.7) x 10⁶

   = 37.3 x 10⁶ people

So, 37.3 x 10⁶ more people live in California than Idaho

Answer:

80

Step-by-step explanation:

These angles are alternate exterior angles and alternate exterior angles are equal when the lines are parallel

12x+8 = 13x+2

Subtract 12x from each side

12x+8-12x = 13x+2-12x

8 = x+2

subtract 2 from each side

8-2 =x

6 =x

Find the measure of the angle

12x+8

12*6+8

Answer:

3.5 yd is your answer

Step-by-step explanation:

First, change in. to ft. Note that the measurement given to you is that 1 ft = 12 in.

Divide the amount of inches you have with 12.

126/12 = 10.5

Next, solve for yards. It is given to you that 1 yard = 3 feet.

Divide the amount of feet you have with 3.

10.5/3 = 3.5

3.5 yd is your answer
