I need help ASAP bc its due in a few minutes and I’m IN A RUSH SO SOMEONE PLEWSE TELL ME THE ANSWER TO THIS

Answer:

D

Step-by-step explanation:

Given that :

Mean = 14

Range = 7

Evaluating the options given :

A. $14, $14, $14, $14, $7, $7

For option A :

Mean = (14 + 14 + 14 + 14 + 7 + 7) = 70 / 6 = 11.66 (incorrect)

B. $14, $14, $14, $14, $14, $21

Mean = (14 + 14 + 14 + 14 + 14 + 21) = 91 / 6 = 15.17 (Incorrect)

C. $13, $13, $13, $15, $15, $15

Range = 15 - 13 = 2 ( Incorrect)

D. $13, $12, $15, $15, $11, $18

Range = (18 - 11) = 7

Mean = (13+12+(15*2)+11+18) / 6 = 84/6 = 14

Option D is Correct

Answer:

3. 4 meters

6. wrong, it should be 7000 meters

7. 2 dm > 10 cm

8. 30 cm = 3 dm

9. 6 km > 5000 m

10. 8 m < 90 dm

Step-by-step explanation:

__________

Answer:

3)40 decimeter = 4 meters

6)Jacob is incorrect because 7 kilometer does not equal 700 meters. The right answer would have been 7000 meters.

7)2 decimeters > 10 centimeters

8) 30 centimeters = 3 decimeters

9) 6 kilometers > 5,000 meters

10)8 meters < 90 decimeters

Therefore, 5000 items can maximize the profit

The correct answer is an option (a)

The money that you make when you sell something for more than it cost you.

For given example,

profit is described by the equation :

[tex]P (x) = -x^2 + 10x -4[/tex]

We need to maximize the profit P(x)

[tex]\Rightarrow \frac{d}{dx}P(x)=0\\\\\Rightarrow \frac{d}{dx}( -x^2 + 10x -4 ) =0\\\\\Rightarrow -2x+10=0\\\\\Rightarrow -2x=-10\\\\\Rightarrow x=5[/tex]

since , x is the number of items made in thousand

Therefore, 5000 items can maximize the profit

The correct answer is an option (a)

Answer:

x = 101/20, y = 1/4

Step-by-step explanation:

Solve the following system:

{-y + 5 x = 25 | (equation 1)

3 y + 5 x - 1 = 25 | (equation 2)

Express the system in standard form:

{5 x - y = 25 | (equation 1)

5 x + 3 y = 26 | (equation 2)

Subtract equation 1 from equation 2:

{5 x - y = 25 | (equation 1)

0 x+4 y = 1 | (equation 2)

Divide equation 2 by 4:

{5 x - y = 25 | (equation 1)

0 x+y = 1/4 | (equation 2)

Add equation 2 to equation 1:

{5 x+0 y = 101/4 | (equation 1)

0 x+y = 1/4 | (equation 2)

Divide equation 1 by 5:

{x+0 y = 101/20 | (equation 1)

0 x+y = 1/4 | (equation 2)

Collect results:

Answer:

A

Step-by-step explanation:

Check the solution by substituting x = [tex]\frac{\pi }{2}[/tex] into the left side of the equation

2sin²x - sinx - 1

= 2sin²([tex]\frac{\pi }{2}[/tex] ) - sin ([tex]\frac{\pi }{2}[/tex] ) - 1

= 2(1)² - 1 - 1

= 2 - 1 - 1

= 0

= right side

[tex]\frac{\pi }{2}[/tex] is therefore a solution to the equation

Happy Pride Month!

Answer:

320m

Step-by-step explanation:

let the two runners be A and B

with Va and Vb as their velocities

velocity=distance/time

Va=720/4*60

=3m/s

Vb=720/5*60

=2.4m/s

Let the 2 runners start from a common position X and meet at Y

so the 2 consecutive meetings happen at X and Y

so we have to find time of meeting at Y as we know that of X (which is t=0)

720=Va*t+Vb*t

t(5.4)=720

t=133.33 or t=720/5.4

therefore distance travelled by B =Vb*t

=2.4*720/5.4

=319.99m

=320m

Answer: Coupon B gives the lower price

The price of coupon B is  3.75 dollars   less than the price of coupon A.

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

Explanation:

15% off means she saves 15% of the original price.

15% of 95 = 0.15*95 = 14.25

Rachel saves $14.25 if she goes with coupon A.

We can see that coupon B gives the lower price because we have more in savings (since 18 is larger than 14.25).

If she goes with option A, then she spends 95-14.25 = 80.75 dollars. If she goes with option B, then she spends 95-18 = 77 dollars. Going with option B means she saves 80.75-77 = 3.75 dollars

Or you could note that 18-14.25 = 3.75 is another way to find out how much is saved when comparing the two coupons.

There are 4 3-coin combinations if we can choose from nickels, dimes, quarters, and half-dollars

The coins to select from are nickels, dimes, quarters, and half-dollars.

So, we have:

Coins (n) = 4

The number of coin to select is:

Coin (r) = 3

The coin combination is then calculated using:

Combination = ⁴C₃

Apply the combination formula

Combination = 4

Hence, there are 4 3-coin combinations if we can choose from nickels, dimes, quarters, and half-dollars

Answer:

The answer is 3

Step-by-step explanation:

It's just wisdom I mean think about it it

1.5 then 3

⭐ Initially, we have to find the reason why it was -1.5:

[tex]\large {\text {$ \sf f (n+1) = -2 f(n) $}}[/tex]

➡️ Having n, then we'll find the value of n, then we'll replace it with the found result.

[tex]\large {\text {$ \sf f (x+1) = -2.x = -1,5 $}}[/tex]

⌛ So, we will have to find what x is worth in this case:

[tex]\large {\text {$ \sf f ( 0,75 +1 ) = -2 \cdot 0,75 $}}[/tex]

[tex]\large {\text {$ \sf f ( 0,75) = -1,5 $}}[/tex]

→ Knowing this...

[tex]\large {\text {$ \sf f ( 1,5 + 1 ) = -2 \cdot 1,5 $}}[/tex]

[tex]\large {\boxed {\boxed {\sf f ( 2,5 ) = -3 }}}[/tex]     [tex]\checkmark[/tex]
