What is the Slope of 7x+4y=20

yKpoI14uk [10]

Answer:

slope = $\frac{-7}{4}$

Explanation:

The general form of the linear line is:

y = mx + c

where:

m is the slope

c is the y-intercept

The given equation is:

7x + 4y = 20

We will start by putting the equation in the general form:

7x + 4y = 20

4y = -7x + 20

$\frac{4y}{4} = \frac{-7x}{4} + \frac{20}{4}$

y = $\frac{-7}{4} x + 5$

Now, comparing our equation with the general form, we would find that:

m = slope = $\frac{-7}{4}$

c = y-intercept = 5

Hope this helps :)

What is the structure of prokaryotic cells?

Dovator [93]

Step-by-step explanation:

The Prokaryotic Cell

Prokaryotes are unicellular organisms that lack organelles or other internal membrane-bound structures. Therefore, they do not have a nucleus, but, instead, generally have a single chromosome: a piece of circular, double-stranded DNA located in an area of the cell called the nucleoid.

According to the official M&M website, 24% of the plain milk chocolate M&M’s produced by Mars Corporation are blue. Anni

Delicious77 [7]

Answer:

d. Both have the same chance because they are both random samples.

Step-by-step explanation:

Regardless of the size of the candy bag, there is no way to elaborate over 40% of blue m&ms when we don't even know how many are inside each bag. the 24% is based on the company production and it does not mean that a bigger or smaller bag will have an increase in blue m&m's.

How does knowing the double 6+6=12 help you solve the near double 6+7=13

forsale [732]

Answer:

6 + 7 = 13

Step-by-step explanation:

We are given the following information in the question:

We know that

$6 + 6 = 12$

We need this information to evaluate

$6+7$

The evaluation can be done with the help of using associative property and distributive property.

Associative property: (a + b) + c = a + (b + c)

The evaluation can be shown as:

$6 + 7\\= 6 + 6 + 1\\=(6 + 6) + 1\\= 12 + 1\\=13$

What is the approximate area of the unshaded region under the standard normal curve below? Use the portion of the standard norma

Harlamova29_29 [7]

The approximate area of the unshaded region under the standard normal curve is 0.86 the option third is correct.

It is given that the standard normal curve shows the shaded area in the curve.

It is required to find the approximate area of the unshaded region under the standard normal curve.

<h3>What is a normal distribution?</h3>

It is defined as the continuous distribution probability curve which is most likely symmetric around the mean. At Z=0, the probability is 50-50% on the Z curve. It is also called a bell-shaped curve.

In the curve showing the shaded region area between:

$\rm P(1 < Z < 2)$

First, we calculate the shaded region area:

From the data given the value of Ф(1) = 0.8413.

P(Z<1) = 0.8413 and

P(Z<2) = 0.9772

The area of the shaded region:

= P(Z<2) - P(Z<1)

= 0.9772 - 0.8413

= 0.1359

The area of the unshaded region:

= 1 - The area of the shaded region ( because the curve is symmetric)

= 1 - 0.1359

= 0.8641 ≈ 0.86

Thus, the approximate area of the unshaded region under the standard normal curve is 0.86 the option third is correct.
