A School Board Randomly Samples 80 Students To Determine Their Opinion On Requiring School Uniforms For

Answers

Answer 1

Answer: 900

Step-by-step explanation:

If 24 out of 80 students are undecided, that is 24/80, or 3/10 (0.3).

To find how many would be undecided out of 3,000 students, multiply 3/10 by 3,000/1, and you get 900, which is your answer

Answer 2

Answer:

900

Step-by-step explanation:

A school board randomly samples 80 students to determine their opinion on requiring school uniforms for the next school year. The table shows the results of the survey.

If there are 3,000 students in the district, how many students do you expect to be undecided about school uniforms?

we can solve with an equation

80 : 24 = 3000 : x

x = 24 * 3000 : 80

x = 900

The statement that is false on Jose drawing cards from the deck is B. For a given number of selections, we can use Joseph's graph to find the number of diamonds that he has picked so far.

What is probability?

Probability can be defined as the ratio of the number of favorable outcomes to the total number of outcomes of an event.

here, we have,

given that,

Jose draws a card from a deck replaces it and draws again he records a number of times he draws an ace. He decides to record the total number of aces that he selects and calculates the proportion of aces that he has selected so far after each pick. He then constructs a graph to visualize his results.

as the graph can not be used:

Jose only recorded the number of aces he selected, not the number of diamonds. Therefore, we cannot use his graph to find the number of diamonds he picked.

However, if we were to use the graph to find the number of aces that Jose has picked so far, then we would be successful. The other statements are true as Jose recorded the cards he took and the cards were replaced after each pick.

The translation used to create the image include the following: A. 5 units down.

What is a translation?

In Mathematics and Geometry, the translation of a geometric figure or graph to the left simply means subtracting a digit from the value on the x-coordinate of the pre-image;

g(x) = f(x + N)

Conversely, the translation a geometric figure downward simply means subtracting a digit from the value on the positive y-coordinate (y-axis) of the pre-image; g(x) = f(x) - N.

Based on the information provided, we have:

(x, y)                               →                  (x + h, y + k)

(1, -1)                              →                   (1, -6).

1 + h = 1

h = 1 - 1

h = 0

-1 + k = -6

k = -6 + 1

k = -5.

Solve the equation using inverse operations. Check your solutions. In your final answer, include all of your work.
1÷4 x³ = –27÷4

Answers

1. First, divide both sides of the equation by 4.

1÷4 x³/4 = –27/4/4

2. Next, on the left side of the equation, use inverse operations to get rid of the division. This will give us x³ = –27.

3. Then, to solve for x, take the cube root of both sides of the equation.

Cube root of x³ = cube root of –27

4. To check your answer, plug in -3 for x in the original equation and solve.

1÷4 x³ = –27/4

1÷4 (-3)³ = –27/4

1÷4 (-27) = –27/4

1 = 1

Since 1 = 1, the answer checks out.

Answer: $158

Step-by-step explanation:

Rita earned a Total of $196 for the time she worked on Monday.

To determine how much money Rita earned for the time she worked on Monday, we need to calculate her earnings for each portion of the day separately.

1. From 8:00 a.m. to 12:00 p.m. (4 hours):

Rita worked for 4 hours within the first 8 hours, so she earns her regular rate of $16 per hour for this time:

Earnings = 4 hours * $16/hour = $64.

2. From 12:30 p.m. to 6:00 p.m. (5.5 hours):

Rita worked for 5.5 hours beyond the initial 8 hours, so she earns 1.5 times her regular rate for each of these hours:

Earnings = 5.5 hours * ($16/hour * 1.5) = $132.

Now, we can sum up Rita's earnings for both periods:

Total earnings = Earnings from the first period + Earnings from the second period

Total earnings = $64 + $132

Total earnings = $196.

Therefore, Rita earned a total of $196 for the time she worked on Monday.

A chemist is weakening an 80% solution by adding a 40% solution. How much of each should he use to get 100 milliliters of a 50% solution? the chemist’s problem is modeled by the system: {0.80x+0.40y=0.50⋅100 (x+y=100 where x is the number of milliliters of 80% solution and y is the number of milliliters of 40% solution.

Answers

Answer: The chemist needs to mix 25 milliliters of the 80% solution with 75 milliliters of the 40% solution to get 100 milliliters of a 50% solution.

Step-by-step explanation:

Let x be the number of milliliters of 80% solution needed, and y be the number of milliliters of 40% solution needed.

From the first equation, we can write:

0.80x + 0.40y = 0.50(100)

Simplifying this equation, we get:

0.80x + 0.40y = 50

Dividing both sides by 0.20, we get:

4x + 2y = 250

From the second equation, we know that:

x + y = 100

Solving this equation for y, we get:

y = 100 - x

Substituting this expression for y into the first equation, we get:

4x + 2(100 - x) = 250

Simplifying this equation, we get:

2x + 200 = 250

Subtracting 200 from both sides, we get:

2x = 50

Dividing both sides by 2, we get:

x = 25

Substituting this value for x into the equation y = 100 - x, we get:

y = 75

Therefore, the chemist needs to mix 25 milliliters of the 80% solution with 75 milliliters of the 40% solution to get 100 milliliters of a 50% solution.
