The director of student health at a large university was concerned that students at his school were consuming too many calories each day. For a certain population of college-age students, it is recommended to consume around 2,000 calories/day. The director would like to test the hypothesis that H0:μ=2000 vs. HA:μ>2000. In a random sample of 50 students the director found that the average was 2105 calories/day with a standard deviation of 288 calories/day. Calculate the appropriate test statistic for this situation. Round your answer to 3 decimal places.

What is the solution of the following quadratic inequality? x2 – 4x – 21 ≤ 0

Answers

Answer:

3, and -7

Step-by-step explanation:

First factor the trinomial

y=x2−4x−21

.

Find 2 numbers knowing sum (-4) and product (c = - 21). They are the numbers in the factor pair (3, -7).

y = (x + 3)(x - 7)

Solving the 2 binomials, we get:

x = -3 and x = 7

We want to solve the given quadratic inequality.

The correct option is the second one, counting from the top.

So we need to solve:

x^2 - 4x - 21  ≤ 0

Because we have the graph, we can avoid all the algebra.

Notice that the equation must be equal to or smaller than zero, then we just need to find the values of x such that the graph intersects the x-axis or is below it.

By looking at the given graph, we can see that the given range goes from -3 to 7

Then the solution is:

-3 ≤ x ≤ 7

This would be represented with a number line going from -8 to 8, two closed circles (because we use the symbols ≤ ≥) at negative 3 and 7, and the region between the circles is shaded.

The correct option is the second one.

Savanna is playing a game with her friends. She tells them to each pick a number, and then she directs them to: 1. Multiply their number by 4 2. Subtract 6 from that number 3. Divide that number by 2. Once they do that, they each tell Savanna their number a. Arturo says his "new" number is -15. What number did Arturo start with?

Answers

Answer:

x  = - 6

Step-by-step explanation:

Let  x  b number, according to instructions´ we must

1.-Multiply  by  4

2.-Subtract  6

3.-Divide by 2

4.-Arturo says his new number  - 15

4,.Which one was the original number   ??

The maths expression for that  is :

(4*x - 6 ) / 2  =  -  15

we solve for x

4x  -  6  = - 30

4x   =  - 24

x  = - 6

Final answer:

To find Arturo's starting number, reverse the given steps: divide by 2, add 6, then multiply by 4.

Explanation:

To find Arturo's starting number, we need to reverse the steps Savanna provided. Let's go through the steps backwards:

  1. Arturo's number after dividing by 2 is -15 * 2 = -30.
  2. Arturo's number after adding 6 is -30 + 6 = -24.
  3. Arturo's number after multiplying by 4 is -24 / 4 = -6.

Therefore, Arturo started with the number -6.

How many integers between 160 and 279 inclusive, are divisible by 7?

Answers

Answer:

17

Step-by-step explanation:

We can put this as an AP (arithmetic progression).

The first number, after 160, that is divisible by 7 is:

161

The last number before 279 that is divisible by 7 is:

273

We can use the formula:

t_n=a+(n-1)d

Where

tn is the nth term [here we take the last one, 273

a is the first term [161]

d is the common difference [7]

and n is the number of terms, we are trying to find this.

Substituting we get:

t_n=a+(n-1)d\n273=161+(n-1)(7)\n273=161+7n-7\n273=154+7n\n7n=119\nn=17

Hence, there are 17 integers
