please help me with this answer​

Answer:

The x-intercept is [tex]\frac{1}{8}[/tex]

The y-intercept is -1

Step-by-step explanation:

Lets find x-intercept:

for y substitute 0

4x+0=12x-1

subtract 4x both sides

0=8x-1

add 1 both sides

1=8x

divide 8 both sides

[tex]\frac{1}{8}[/tex]=x

lets find y-intercept:

for x substitute 0

4(0)+y=12(0)-1

multiply 4(0) and 12(0) which would equal 0 in this case, you dont have to write the 0s.

y=-1

Hopefully it helps

Answer:

62.48 ft.

Step-by-step explanation:

Initial height: 50 ft.

First rebound: 10 ft.

Second rebound: 2 ft.

Third rebound: 0.4 ft.

Fourth rebound: 0.08 ft.

If we approximate the fourth rebound to zero, we'll have:

50 + 10 + 2 + 0.4 + 0.08 = 62.48 ft.

Answer:

369000

Step-by-step explanation:

i think its right you have to take 150,000 and subtract 18% from it and then take the new number you get and multiply that by 3

Part A: 5 out 25 lobsters have dangerous levels of mercury

Part B: the 95% confidence interval is given by (4.45, 5.65)

since everything is given all I had to do is find the critical value which can be found from the resource packet = 2.064

Using the formula we find 5.05+-2.064*1.45/5 = ( 4.45,5.65)

For this case, we have 95% of confidence that the true mean for the average number of lobsters with dangerous levels of mercury is between 4.45,5.65

Answer:

160

Step-by-step explanation:

First, lets assign a varible x. Let x be the number where 75% of x is 120. Next, we can convert the words of the problem into an equation. Now we have, 75% * x = 120 = 0.75x = 120. By multiplying both sides by 100, we get, 75x = 12000. So, x = 160.

Answer:

4.5833feet

Step-by-step explanation:

Given the elevation of a water pipe as 4 7/12 feet

Expressing as decimal

4 7/12  

= 4 + 7/12

=  4 + 0.5833

= 4.5833

Hence the elevation of the pipe expressed as a decimal is 4.5833feet

The game is formed such that a duck is either winning duck or a non winning duck .

there is no other result for any duck present in the game .

Also choosing a duck is a fair game it is independent of any prior situation .

here we would be using a basic probability formula , that is

Probability of a result = number of items in favour of that result divide by total number of items present in the game .

Answer:

The answer is 6.

Step-by-step explanation:

you have 3/4 divided by 1/8, first you find a common denominator, which is 8. Second you do 3 x 2 and 4 x 2, you should get 6/8 divided by 1/8, and 6 divided by 1 is still 6.

Answer:

6

Step-by-step explanation:

3 /4   × 8 /1 =

3×8/4×1=24/4

3x8 is the numerator 4x1 is the denominator

24/4=6

3/4÷1/8=6

Answer:

16800

Step-by-step explanation:

since the equaltiuon is 16.8*1000

1 kg = 1000 grams.

16.8 kg x 1000 = 16,800 grams

answer:

y=1/4x-7

Step-by-step explanation:

equations with the same slope are parallel no matter the y-intercept

Answer:

I don't think it's specified but I can tell you the slop has to stay the same but the y-intercept ha

s to be a different number.

if over a certain point the all you have to do is plug the points into x and y and remove the y intercept. An example is what line is parallel to y=1/4x+2 and crosses point (4,2).

Then you first have to plug in x and y and remove the y intercept to find a new y intercept. 2=1/4(4)+B

Next is to put together common like terms. 2=1+B

Then subtract one because that's it's opposite leaving B=1

then you substitute or replace the old y intercept with the new one making the answer Y=1/4x+1

I hope this will help you.

Answer: give me brainliest now

Step-by-step explanation:

Answer:

(-4;2)

Step-by-step explanation:

1. if y=1/2 x+4, then 2y=x+8; it is possible to re-write as x-2y+8=0;

2. if x+4y=4, it is possible to re-write it as x+4y-4=0;

3. if x-2y+8=0 and x+4y-4=0, then x-2y+8=x+4y-4; ⇒ -2y+8=4y-4; ⇒ 6y=12; ⇔ y=2.

4. if y=2, then it is possible to substitute its value into any equation given in the condition:

x+4y=4 (substitution y=2); ⇒ x+8=4; ⇒ x= -4.

5. finally x= -4; y=2. It means (-4;2)

PS. the suggested solution is not the only way to resolve this task.

Answer:

TS=22

Step-by-step explanation: Since we know the triangles are proportional, we need to set up an proportion to find TS. First, let find which sides are correspond with each, TS and MN does and US and NQ does. So we set up a proportion that includes.

TS/US=MN/NQ: Let plug in the numbers

3x+1/26=5x-2/39:  Then cross multiply

39(3x+1)=26(5x-2): Then simplify

117x+39=130x-52: Subtract 117x from both sides

39=13x-52: Add 52 to both sides

  91=13x: Divide 13 by both sides

  7=x: Then plug it in to TS

3(7)+1=22

Answer:

[tex]P_D=61.1*10^{-4}[/tex]

[tex]R_r=480[/tex]

Step-by-step explanation:

From the question we are told that

Homicide rate in US [tex]R_U=62.4\ per\ one\ million[/tex]

Homicide rate in Britain [tex]R_B=1.3\ per\ one\ million[/tex]

Generally the equation for probability of homicide is mathematically given as

[tex]P=\frac{R}{10^6}[/tex]

Generally the equation for probability of homicide in US is mathematically given as

[tex]P_U=\frac{62.4}{10^6}[/tex]

[tex]P_U=62.4*10^{-4}[/tex]

Generally the equation for probability of homicide in Britain is mathematically given as

[tex]P_B=\frac{1.3}{10^6}[/tex]

[tex]P_B=1.3*10^{-5}[/tex]

a)Generally the difference b/w the probabilities P_D is mathematically given as

[tex]P_D=P_U-P_B[/tex]

[tex]P_D=62.4*10^{-4}-1.3*10^{-5}[/tex]

[tex]P_D=61.1*10^{-4}[/tex]

Therefore US annual homicide is [tex]P_D=61.1*10^{-4}[/tex] greater than Britain's

b)Generally the Relative risk is R_r is mathematically given as

[tex]R_r=\frac{P_U}{P_B}[/tex]

[tex]R_r=\frac{62.4*10^{-4}}{1.3*10^{-5}}[/tex]

[tex]R_r=480[/tex]
