You receive a fax with six bids (in millions of dollars):2.2,1.3,1.9,1.2 2.4 and x is some number that is too blurry to read. Without knowing what x is, the median a. Is 1.9 b. Must be between 1.3 and 2.2 c. Could be any number between 1.2 and 2.4

Answers

Answer 1

Answer:

Answer:

b. Must be between 1.3 and 2.2

Step-by-step explanation:

The formula for calculating median is :

When n(number of observations in data) is odd = $((n+1)/(2) )^(th) observation$
When n is even = $(((n)/(2))^(th)obs. + ((n)/(2) + 1)^(th) obs. )/(2)$

Since in our data n is even so we use the formula for calculating median

= $(((n)/(2))^(th)obs. + ((n)/(2) + 1)^(th) obs. )/(2)$

First arranging data in ascending order we get :

1.2, 1.3, 1.9, 2.2, 2.4 and since we know nothing about our sixth value x so we assume that it may take any position in our data.

Now there may be cases for which position is x on ;

If x is the first obs in our data then our median = $(3^(rd)obs + 4^(th)obs )/(2)$ = $(1.3+1.9)/(2)$

= 1.6

If x is between 1.2 and 1.3 then also median will be 1.6 .

If x is between 1.3 and 1.9 then median will be somewhere between 1.3 and 1.9 .
If x is between 1.9 and 2.2 then median will be somewhere between 1.9 and 2.2 .

And If x is between 2.2 and 2.4 or after 2.4 then median = $(3^(rd)obs + 4^(th)obs )/(2)$

= $(1.9+2.2)/(2)$ = 2.05 .

So from all these observations we conclude that without knowing what x median of data must be between 1.3 and 2.2 .

Answer 2

Answer:

Final answer:

The median of a set of bids can be found by arranging them in numerical order and selecting the middle value.

Explanation:

The median is the middle value of a set of data arranged in numerical order. In this case, we have a set of six bids: 2.2, 1.3, 1.9, 1.2, 2.4, and x (blurred number). To find the median, we first need to arrange the bids in numerical order:

Since there are six bids, the middle value will be the fourth number in the ordered list. Therefore, the median is 2.2.

Which polynomials are prime? Check all of the boxes that apply.x² +9
x²_9
x2 + 3x + 9
-2x² +8

Answers

Final answer:

A polynomial is prime if it cannot be factored into polynomials of lower degree. In this case, x² +9 and x² + 3x + 9 are prime polynomials while x² -9 and -2x² +8 are not.

Explanation:

In mathematics, a polynomial is said to be prime if it cannot be factored into polynomials of lower degree, at least one of which must be non-constant. To determine if a polynomial is prime, we try to factor it. In our case:

x² +9 is a prime polynomial because it is a sum of squares and cannot be factored into real polynomials of lower degree.
x² -9 is not a prime polynomial because it can be factored into (x-3)(x+3).
x² + 3x + 9 is a prime polynomial because it cannot be factored into real polynomials of lower degree.
-2x² +8 is not a prime polynomial as it can be factored into -2(x²-4).

Answers

Hello.

The answer is:

First find Lcm of 40 and 30 that is 120 (2*2*2*3*5)

the convert 120 by divinding by 30 = 120/30=4

So that means 2 hours later (2 hours after 12) so the answer is 2 pm

Quan likes to exercise by running every day. On average, he runs 5 miles each day. This varies by about 0.3 mile. What are the maximum and minimum numbers of miles Quan is expected to run each day?

Answers

Answer:

Quan runs a maximum of 5.3 miles and a minimum of 4.7 miles every day.

Step-by-step explanation:

Let x= the actual measurement.

|actual − ideal|≤ tolerance

Use an absolute value inequality to express this situation.

|x−5|≤0.3

Rewrite as a compound inequality.

−0.3≤x−5≤0.3

Solve the inequality.

4.7≤x≤5.3

Answer the question. Quan runs a maximum of 5.3 miles and a minimum of 4.7 miles every day.

Karly is choosing between two health clubs. Yoga Studio A charges a membership fee of $22.00 and $24.50 per month. Yoga Studio B charges a membership fee of $47.00 and $18.25 per month. At how many months will they cost the same? *

Answers

Answer:

4 months

Step-by-step explanation:

Given

Studio A

$Membership = \$22.00$

$Monthly = \$24.50$

Studio B

$Membership = \$47.00$

$Monthly = \$18.25$

Required

Determine when the cost will be the same

For both, we have the total cost to be:

$Cost = Membership + Monthly\ Cost * m$

Where m represents the number of month

For Studio A:

$Cost = 22 + 24.5 * m$

For Studio B:

$Cost = 47 + 18.25 * m$

Equate both expressions to get the required month

$47 + 18.25 * m = 22 + 24.5 * m$

$47 + 18.25 m = 22 + 24.5m$

Collect Like Terms

$47 - 22 = 24.5m - 18.25 m$

$25= 6.25m$

Reorder

$6.25m = 25$

Solve for m

$m = 25/6.25$

$m = 4$

Hence, it'll take 4 months
