Use slopes and y-intercepts to determine if the lines -3x – 3y = 1 and -3x – 4y = 5 are parallel.

N76 [4]

Answer:

they are not parallel

Step-by-step explanation:

Given the equations -3x – 3y = 1 and -3x – 4y = 5

Get the slope of each line

REwrite in the form y = mx+c

For the line -3x-3y = 1

-3y = 3x + 1

y = 3x/-3 + 1/-3

y = -x - 1/3

Slope m = -1

For the line -3x - 4y = 5

-4y = 3x + 5

y = -3/4 x - 5/4

Slope of the line is -3/4

Hence since both lines have different slopes, they are not parallel

Hailey solved the problem 2.55 ÷ 1.5 and got the quotient 0.17. Her work is below. Is Hailey’s process Correct? Use mathematics

Evgesh-ka [11]

When Hailey solved the problem 2.55 ÷ 1.5 and got the quotient 0.17, the process isn't correct as she should put the 1 before the point.

<h3>What is a quotient?</h3>

A quotient is a quantity produced by the division of two numbers in arithmetic. The quotient is widely used in mathematics and is also known as the integer part of a division, a fraction, or a ratio.

The number that is being divided (in this case, 2.55) is called the dividend, and the number that it is being divided by (in this case, 1.5) is called the divisor. The result of the division is the quotient.

This will be:

= 2.55 / 1.5

= 1.7

She made a mistake by writing 0.17.

Sergeu [11.5K]

Answer:

$\mu_{x}=np$

$\sigma^2_{X}=np(1-p)$

Step-by-step explanation:

∵ When x is a random variable having distribution B(n, p), then for sufficiently large value of n, the following random variable has a standard normal distribution,

$\frac{x-\mu}{\sigma}\sim N(0,1)$
