Use the given information to write the equation of the line in slope-intercept form: y = mx + b

worty [1.4K]

Answer:

$y =2x + 3$

Step-by-step explanation:

Given

(-2,-1) and (3,9).

Required

Determine the line equation

First, we calculate slope (m)

$m = \frac{y_2 - y_1}{x_2 - x_1}$

Where

$(x_1,y_1) = (-2,-1)$

$(x_2,y_2) = (3,9)$

So, we have:

$m = \frac{9 - (-1)}{3- (-2)}$

$m = \frac{9+1}{3+2}$

$m = \frac{10}{5}$

$m = 2$

The equation is then calculated using:

$y - y_1 = m(x - x_1)$

$y - (-1) =2(x - (-2))$

$y - (-1) =2(x +2)$

$y +1 =2(x +2)$

Open bracket

$y +1 =2x + 4$

Subtract 1 from both sides

$y +1-1 =2x + 4-1$

$y =2x + 3$

Im having difficulty pls help me as soon as possible bc im about to have a nervous break down thanks

Answer:

A: 85%, 2 $\frac{1}{5}$ , 3.24, $\frac{19}{4}$

B: covert numbers into percent

Step-by-step explanation:

We have:

$\frac{19}{4}$ , 2 $\frac{1}{5}$ , 85%, 3.24 --> let's convert them into percentages like the 85, to determine which one is greatest/least:

85% --> 85% (already a percent)

$\frac{19}{4}$ --> to convert into percent: (19÷4) x 100 = 475%

2 $\frac{1}{5}$ --> convert first into improper fraction then into percent: (11/5) x 100 = 220%

3.24 --> multiply by 100: 3.24 x 100 = 324%

From least to greatest: 85%, 220%, 324%, 475%

= 85%, 2 $\frac{1}{5}$ , 3.24, $\frac{19}{4}$

Part B:

In part A, to determine the numbers from least to greatest, we rewrote the numbers all into percentage form by first converting into decimal form and then multiplying by 100.

A school will offer pizza on Friday's if at least 30% of the students will buy it. A sample of 50 students asked if they would b

Whitepunk [10]

Answer:

0.0614

Step-by-step explanation:

Solution:-

- The school offers pizza on friday when at-least 30% students are willing to buy.

- The minimum required proportion of students, p = 30%

- A sample of n = 50 students were taken and out of the sample x = 10 people responded willing to buy pizza.

- We will denote a random variable X: the number of students willing to buy Pizza on fridays.

- For the sample of n = 50, for Pizza to be offered on friday the expected number of student who should opt for buying must be at-least:

Expected ( Mean - u ) = n*p = 50*0.3 = 15 people.

- The standard deviation for the normal distribution can be determined as follows:

standard deviation ( s ) = √n*p*(1-p)

= √50*0.3*(0.7)

= √10.5 = 3.2404

- We will assume that the random variable X follows normal distribution:

X ~ Norm ( 15 , 3.2404^2 )

- To determine the probability of sample of size n = 50 with proportion or lower. The number of people willing to buy pizza on friday as per survey are x = 10.

- Evaluate the standard normal ( Z-score ):

P ( X < x ) = P ( Z < ( x - u ) / s )

P ( X < 10 ) = P ( Z < ( 10 - 15 ) / 3.2404 )

P ( X < 10 ) = P ( Z < -1.54301 )

- Use the standard normal tables to determine the value of P ( Z < -1.54301 ):

P ( X < 10 ) = P ( Z < -1.54301 ) = 0.0614

Answer: The probability of getting a sample with the proportion or lower given a population with a proportion of .30 is 0.0614.
