What is the y intercept of the equation y=4x+1

Answer:

The needed line equation is :  x + y + 2 = 0

Step-by-step explanation:

The slope m of the given line equation = -1

The points through which the line passes  is (1,-3).

Now,as we know:

The POINT SLOPE form of the equation with point (x0,y0) is given as:

y - y0 = m (x-x0)

So, the equation if line q=with m = -1 and (x0,y0) = (1,-3) is given as

y  - (-3)  = -1( x  - 1)  

or, y + 3 = 1 -x

or, x + y + 2 = 0

Hence, the needed line equation is :  x + y + 2 = 0

Final answer:

The price of one movie ticket, represented as p, can be found by dividing the total cost of $35 by the number of friends, which is 4. The equation is 4p = 35, and solving for p gives $8.75 per ticket.

Explanation:

To calculate the price of one movie ticket when you and three friends spend a total of $35 on tickets, you would set up an equation where p represents the price of one ticket. The equation will be:

4p = 35

To solve for p, you would divide both sides of the equation by 4:

p = 35 / 4

p = $8.75

Therefore, the price of one movie ticket is $8.75. The calculated value of p is $8.75, indicating that each movie ticket costs $8.75. This method allows for the precise determination of individual ticket prices based on the total amount spent by the group, facilitating accurate financial planning for movie outings.

Step-by-step explanation:

Sorry I cant explain it.

Answer:

w = (y+1)/(2+a)

Step-by-step explanation:

y-aw=2w-1

y+1 = 2w+aw (collecting the like terms)

y+1 = w(2+a)

w(2+a) =y+1

w = (y+1)/(2+a)

Part A

p = 0.5 is the hypothesized population proportion

x = 570 is the number of successes

n = 1100 is the sample size

phat = x/n = 570/1100 = 0.518182 is the approximate sample proportion

SE = standard error

SE = sqrt(p*(1-p)/n)

SE = sqrt(0.5*(1-0.5)/1100)

SE = 0.015076 which is approximate

----

We have enough to compute the z test statistic

z = (phat - p)/(SE)

z = (0.518182 - 0.5)/(0.015076)

z = 1.206023

z = 1.21

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

Part B

Compute the probability of getting a z score larger than 1.21

P(Z > 1.21) = 1 - P(Z < 1.21)

P(Z > 1.21) = 1 - 0.8869 .... see note below

P(Z > 1.21) = 0.1131

note: the value 0.8869 comes from the table that I've attached as an image below. I have marked in red the proper row and column used to look up the value. The z table is commonly found in statistics textbooks toward the back sections. There are also many free online z tables you can search out as well. I used a z table found online. Alternatively, you can use your TI83 or TI84 calculator to compute the area under the normal curve. You would use the normalCDF function.

The z-statistic for testing whether the proportion of voters favoring the Republican candidate is greater than 0.50 is approximately 1.36. The P-value associated with this z-statistic is roughly 0.0869, indicating the probability of observing such sample results if the true proportion was indeed 0.50.

A newspaper conducted a statewide survey regarding the 1998 race for state senator, sampling n=1100 registered voters, with 570 favoring the Republican candidate. We are testing the hypotheses H₀: p = .50 against Ha: p > .50, where p represents the proportion of registered voters in the state who would vote for the Republican candidate. The steps for calculating the z-statistic and the P-value are outlined.

Calculation of the z-statistic:

To calculate the z-statistic for this test, we use the formula z = (p' - p₀) / √(p0(1 - p₀) / n), where p' = 570/1100 = 0.518 is the sample proportion, and p₀ = 0.50 is the null hypothesis proportion. Plugging in the numbers, we get:

z = (0.518 - 0.50) / √(0.50(1 - 0.50) / 1100) ≈ 1.36.

Calculation of the P-value:

The P-value is the probability that, assuming H0 is true, we would observe a sample proportion as extreme as or more extreme than the one observed. For a z-statistic of 1.36 in a right-tail test, the P-value can be found using a Z-table or software, resulting in:

P-value ≈ 0.0869.

To conclude, based on the calculated P-value, the decision on whether or not to reject the null hypothesis would depend on the level of significance (α) chosen for the test.

Answer:

Teo is 11 years old and Richard is 26 years old.

Step-by-step explanation:

Let R be the age of Richard and T be the age of Teo.

First set up the equations:

The combined age of Teo and Richard is 37:

R+T=37

Richard is four years old than twice Teo's age:

R=2T+4

Then, solve the equations:

Substitute (2) to (1) and solve for T:

(2T+4)+T=37

3T=11

T=11

Solve for R using (2):

R=2(11)+4

R=22+4

R=26

Answer:

t = 0.77

Step-by-step explanation:

f(t) = 11 × (1.5^t)

f(t) = 15

11 × (1.5^t) = 15

1.5^t = 1.364 (3d.p)

log1.5(1.364) = t

t = 0.77 (2d.p)

Answer:

[tex]x=5, y=6[/tex]

Step-by-step explanation:

we know that

If triangles ABC and AED are congruent, then its corresponding sides are congruent

so

BC=ED

AC=AD

substitute the given values

[tex]x=y-1[/tex] ----> equation A

[tex]3x-2=2y+1[/tex] ----> equation B

solve the system by substitution

substitute equation A in equation B

[tex]3(y-1)-2=2y+1[/tex]

solve for y

[tex]3y-3-2=2y+1[/tex]

[tex]3y-2y=1+5[/tex]

[tex]y=6[/tex]

Find the value of x

[tex]x=y-1[/tex] ----> [tex]x=6-1=5[/tex]

therefore

[tex]x=5, y=6[/tex]

Answer:

275 miles in 5 hours

55 miles in one hour

Check

to check if im right

275×2 would be how many miles she drove in 10 hours rght ? 275×2=550

550 miles in 10 hours

we know one hour is 55 miles & 5 hours is 275 & 10 hours is 550

10 hours plus 3 hours = 13 hours right ?

55 ×3 = 165

550 +165=715

715 miles in 13 hours

Step-by-step explanation:

715÷13 to get how many miles she drove in one hour .

=55 miles in 1 hour .

then multiply 55 ×5 to get how many miles she drove in 5 hours

55×5=275

275 miles in 5 hours

The first one considering you are starting at -7/11... no other number line starts at or goes beyond -7/11....

Answer:

The answer would be -3/10. Therefore, the only timeline that has -7/10, 4/10 and -3/10 is the first one.

Step-by-step explanation:

The answer to the problem is -3/10, as -7 + 4 is -3, and the 10 stays the same. The first timeline accommodates all of the numbers well, and you can see how you get the answer. Hope this helps!

Final answer:

The increase in ice cream sales as the weather gets warmer is an example of correlation.

Explanation:

The best description for this situation is b.) Based on the data, this is an example of correlation. Correlation refers to a relationship or pattern between two variables. In this case, as the weather gets warmer, there is an increase in ice cream sales. However, correlation does not imply causation, meaning one variable does not cause the other. It is more likely that the warmer weather influences both the increase in ice cream sales and other factors that may affect sales.
