What is the slope-intercept form of the following equation?

1 answer:

5 0

Y=-.5x+3
Explanation: Move the x to the other side by subtracting it from both sides, you end up with 10y=30-5x then you divide 10 from both sides and you end up with y=-.5x+3

Assume that a procedure yeilds a binomial with n trial and the probability of success for one trial is p. Use the given values o

Alexeev081 [22]

The value of minimum usual value is, $\mu-2\sigma=-119.2$

The value of maximum usual value is, $\mu+2\sigma=1311.2$

Given the values of the parameters of Binomial Distribution are,

Total number of trials (n) = 1490

probability of success in one trial is (p) = 2/5

The probability of failure in on trial is given by,

$q=1-p=1-\frac{2}{5}=\frac{5-2}{5}=\frac{3}{5}$

For Binomial distribution we know that,

Mean $(\mu)=np=1490\times\frac{2}{5}=596$

and Standard Deviation $(\sigma)=\sqrt{npq}=\sqrt{1490\times\frac{2}{5}\times\frac{3}{5}}=357.6$

Now, calculating the required measurement we get,

The minimum usual value is given by,

Mean -2 Standard Deviation $=\mu-2\sigma=596-2\times357.6=-119.2$

The maximum usual value is given by,

Mean + 2 Standard Deviation $=\mu+2\sigma=596+2\times357.6=1311.2$

Hence the minimum and maximum usual values are -119.2 and 1311.2 respectively.

Can you help me i dont understand U_U

LuckyWell [14K]

Answer:

$7.76

Step-by-step explanation:

So you can express the price in the slope-intercept form: y=mx+b where m is the slope, but in this context it's the price per km, and b is the y-intercept, but in this context it's the base price (how much it costs even if the length is 0 km)

So it gives you the slope of $0.22 per km. so you now have the equation

y = 0.22x + b

To find the base amount or y-intercept, you can take some of the given points, the price will be y, and the length will be x.

I'll use the point (6, 4.68)

Plugging these values into the equation you get:

4.68 = 0.22(6) + b

multiply

$4.68 = 1.32 + b$

subtract 1.32 from both sides

$3.36 = b$

So now we have the full equation:

y = 0.22x + 3.36

Now to find the price if the length is 20km, simply plug in 20 as x

y = 0.22(20) + 3.36

Multiply

y = 4.4 + 3.36

Add

y=7.76

Can someone help me find 5 + 8m = -18, please?

Naddika [18.5K]

Answer:

m=-2.875

Step-by-step explanation:

1:. subtract 5 from both sides --> 8m =-23

2:. divide by 8 --> m= -23/8 or about - 2.875=m

358 tickets to the school basketball game on Friday were sold. Student tickets were $1.50 and adult tickets were $3.25. ASB made

Irina-Kira [14]

Answer:

x+y = 358

1.50x + 3.25y = 725.25

Step-by-step explanation:

Let the number of student tickets be x

Let the number of adult tickets be y

If 358 tickets were sold, then;

x+y = 358

If Student tickets were $1.50 and adult tickets were $3.25 with $725.25 made, the required equation is expressed as:

1.50x + 3.25y = 725.25

Hence the two equations that represent the problems are:

x+y = 358

1.50x + 3.25y = 725.25
