Intercepts from a graph

Mathematics
1 answer:
Annette [7]2 years ago
8 0

Answer:

Y-intercept: (0,-0.7)

X-intercept: (-1.2,0)

Explanation:

The Y-intercept is the spot where the line crosses the Y axis (the vertical axis). This always occurs where X=0. For this problem the Y value at this point is -0.7. So, for the coordinates (X,Y) X is 0 and Y is -0.7 so it is (0,-0.7)

The X-intercept is the spot where the line crosses the X axis (the horizontal axis). This always occurs where Y=0. For this problem the X value at this point is -1.2. So, for the coordinates (X,Y) X is -1.2 and Y is 0 so it is (0,-0.7)

olga nikolaevna [1]

Answer:

60/100 and x/20 and x=12

Step-by-step explanation:

60 % of 20

60/100 = x/20

cross product

60 * 20 = 100x

divide by 100

1200/100 =x

12=x

Answer:60/100 = x/20    x= 12

hope it's right

1) Your friend Taylor missed class today and needs some help identifying solutions of systems. Explain to Taylor where to find t
Mashcka [7]

Answer:

Ques 1:

Let us consider the system of equations,

2x+y=3 and 3x-y=2

It is known that 'The intersection points of the graphs of the system of equations are the solutions of the system of equations'.

So, after plotting the given graphs, we see that from the first graph,

The only intersection point is (1,1).

Thus, the solution of the system is x= 1 and y= 1.

Ques 2:

We have the functions, f(x)= 2x+1 and g(x)= 2x^2+1.

Plotting the graphs of both the functions is shown by graph 2, we see that,

The intersection points are (0,1) and (1,3)

Hence, the function have equal values only at x= 0 and x= 1 but not at x= 3.

The amount of calories consumed by customers at the Chinese buffet is normally distributed with mean 2617 and standard deviation
Eduardwww [97]

Answer:

a) N(2617, 586)

b) 0.3613 = 36.13% probability that the customer consumes less than 2409 calories.

c) 0.4013 = 40.13% of the customers consume over 2764 calories

d) 3981 calories.

Step-by-step explanation:

Problems of normally distributed samples can be solved using the z-score formula.

In a set with mean \mu and standard deviation \sigma, the zscore of a measure X is given by:

Z = \frac{X - \mu}{\sigma}

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

In this question, we have that:

\mu = 2617, \sigma = 586

a. What is the distribution of X?

Here we first place the mean, then the standard deviation.

N(2617, 586)

b. Find the probability that the customer consumes less than 2409 calories.

This is the pvalue of Z when X = 2409. So

Z = \frac{X - \mu}{\sigma}

Z = \frac{2409 - 2617}{586}

Z = -0.355

Z = -0.355 has a pvalue of 0.3613

0.3613 = 36.13% probability that the customer consumes less than 2409 calories.

c. What proportion of the customers consume over 2764 calories?

This is 1 subtracted by the pvalue of Z when X = 2764. So

Z = \frac{X - \mu}{\sigma}

Z = \frac{2764 - 2617}{586}

Z = 0.25

Z = 0.25 has a pvalue of 0.5987

1 - 0.5987 = 0.4013

0.4013 = 40.13% of the customers consume over 2764 calories

d. The Piggy award will given out to the 1% of customers who consume the most calories. What is the fewest number of calories a person must consume to receive the Piggy award?

Top 1%, so the 100-1 = 99th percentile.

The 99th percentile is the value of X when Z has a pvalue of 0.99. So it is X when Z = 2.327. So

Z = \frac{X - \mu}{\sigma}

2.327 = \frac{X - 2617}{586}

X - 2617 = 2.327*586

X = 3980.6

Rounding to the nearest calorie, 3981 calories.

Can u guys PLEASE answer this question ASAP. THIS IS EXTREMELY URGENT
Ulleksa [173]

Answer:

The answer to your question is $56  

Step-by-step explanation:

Data

Payment before noon = $11.20

Payment after noon = $11.20/2

Time from 9:00 to 16:00

Process

1.- Calculate the hours worked before noon and the hours worked after noon.

    Before noon = 12:00 - 9 = 3 hours

    After noon = 16:00 - 12:00 = 4 hours

2.- Calculate the payment

Payment = (3 x 11.2) + (4 x 11.2/2)

               = 33.6 + 22.4

               = $56
