What Is The Solution To The System Of Linear Equations Graphed Here?A (2,-1)B (-1,2)C (2,1)D) No Solution

Answers

Answer 1

Answer:

One solution, A) (2 , -1)

Step-by-step explanation:

The solution is where the two lines intersect. If the lines do not intersect, it is no solution. If the line intersects once (like in the picture), it has one solution. If it intersects more than once (x), then it will have x amount of solutions.

In this case, the intersection is at (2 , -1), therefore, A) (2 , -1) is your answer.

Answer 2
A. (2, -1)
Just look where the red dot is and look from x to y.

is the total they spent?

Answers

they leave a tip of $1.20, the total would be $9.20

Answer:

$9.2

Step-by-step explanation:

Four friends spend 8 dollars. However, they also leave a 15% tip. So, you will have to multiply .15 by 8. However that is not it. After, you have to add the product of that with 8. Which will give you 9.2.

"A supplier of digital memory cards claims that no more than 1% of the cards are defective. In a random sample of 600 memory cards, it is found that 3% are defective, but the supplier claims that this is only a sample fluctuation. At the 0.01 level of significance, test the supplier's claim that no more than 1% are defective."

Answers

Answer:

Both the values fall in the critical region so we reject H0: p ≤ 0.01  and conclude that the results are significantly different from chance identification and it is not a sample fluctuation.

Step-by-step explanation:

1) Formulate the hypothesis

H0: p ≤ 0.01 against  the claim Ha: p > 0.01

2) Choose the significance level ∝= 0.01

3) The test statistics under H0 is

z= x -np /√npq  ( without continuity correction)

z= x ± 1/2 -np /√npq  ( with continuity correction)

4) the critical region is z> ±2.33 because the alternate hypothesis is stated on greater than basis.

5)Computations:

Z=  x -np /√npq  ( without continuity correction)

Z= 6- 600( 0.03)/√ 600( 0.03)(0.97)

z= - 2.82  ( without continuity correction)

z= x ± 1/2 -np /√npq  ( with continuity correction)

Z= (6-0.5)- 600( 0.03)/√ 600( 0.03)(0.97)

z= -12.5/4.1785

z= -0.29915  ( with continuity correction)

6) Both the values fall in the critical region so we reject H0: p ≤ 0.01  and conclude that the results are significantly different from chance identification and it is not a sample fluctuation.

Two barrels contain equal quantities of honey. From one barrel, 37 gallons of honey are drawn. From the other barrel, 7 gallons of honey are drawn. The quantity remaining in one barrel is now seven times that remaining in the other barrel. How much did each barrel contain at first?

Answers

At the start, each barrel has the same amount of honey, so:

Barrel 1 has X gallons

Barrel 2 has X gallons.

from 1, they extract 37 gallos, and from 2 they extract 7 gallons, so now:

Barrel 1 has X - 37

Barrel 2 has X- 7

and now, the quantity in the Barrel 2 is seven times the quantity in the barrel 1, so:

X- 7 = 7*(X - 37)

we need to find X.

X - 7 = 7*X - 37*7 = 7*X - 259

X - 7*X = 7 - 259

-6*X = -252

X = 252/6 = 42

So at the start, each barrel has 42 gallons of honey.

Nancy works at Yogurty's for $5.35 an hour. Last week, she worked 30 hours.
a) How much did she earn?
b) Nancy received a 25¢/hour raise this week. She worked 25 hours. How much did she earn?

Answers

Answer a) $160.5
Answer b) $140
answer for A:

$160.50

explanation:

she worked for 30 hours so that means she earned $5.35 per hour. so all you have to do here is $5.35 x 30 which gives you $160.50.


Answer for B:

$140

explanation:

25¢ is the same as $0.25 so first of all, add 0.25 onto $5.35 which gives you $5.60.

Now, (this is just the same equation as part A but with different numbers), since she earns $5.60 per hour and worked 25 hours, all you have to do it $5.60 x 25 which gives you $140.

B. y=1.5x+7
C. y=2x+5
D. y=1.25x+8

Answer:

y=5/4x+8 Answer Choice D).

Step-by-step explanation:

m=(y2-y1)/(x2-x1)

m=(18-13)/(8-4)

m=5/4

y-y1=m(x-x1)

y-13=5/4(x-4)

If a is inversely proportional to x, a=15 when x=25 find the constant of variation, k

Answers

Answer:

Step-by-step explanation:

"Inversely proportional to x" in this situation is represented by a = k/x.

Find k:

Let a = 15 and x = 25, then calculate k:

15 = k/25)

Multiplying both sides by 25 yields k = 15(25), or k = 3/5

Answer:

4+7/16

Answer is 11/16

Step-by-step explanation:

Transform the expression then calculate

Answer:

11/16

Step-by-step explanation:

First- make sure they have the same denominator (the number located at the bottom)

(the denominator is the least common multiple (LCM) or essentially where the numbers meet up)

^ 4 and 16 meets up at 16.

^7/16 already has 16 as the denominator, however 1/4 does not.

Therefore-

1/4 * 4/4 + 7/16 * 1/1

^ 4/16 + 7/16

(they have the same denominator, therefore when you add you DO NOT change the denominator)

4+7 is 11- and you keep the denominator

11/16 is a number which you can NOT simplify.

Therefore ^ 11/16 is your answer
