for each graph caculate the slope of each line

The correct option 1. the slope of Equation A is steeper because 4/5 is bigger than 2/5.

The format of a linear function is as follows:

y = ax + b

That where:

Given by: Linear equation A

y = 4/5 x.

Points (0, 2) and pass through linear equation B. (5, 4).

Given that changes in y divided by change in x determines the slope between two points, we have that:

m = (4 - 2)/(5 - 0)

m = 2/5

Equation A is steeper as it contains a higher slope, so the appropriate response is:

Due to the fact that 4/5 is greater than 2/5, Equation A has a steeper slope.

Which statement is entirely correct?

Answer: 8 + i

Step-by-step explanation:

The complex number 8/1+i can be written in standard form as 8 + i. In standard form, a complex number is written as a+bi, where a is the real part and bi is the imaginary part. In this case, the real part is 8 and the imaginary part is i. Therefore, the standard form of the complex number 8/1+i is 8 + i.

Answer:  [tex]\textsf{\$1583.9 per day}[/tex]

-------------------------------------------------------------------------------------------------------------

Given:  [tex]\textsf{The table with the information}[/tex]

Find:  [tex]\textsf{The average daily balance of Elliott's account for the month of June}[/tex]

Solution: In order to get the average daily balance, we need to use a formula where we have a weighted balance for each day.  For example, out of the 30 days in June, 9 of the days there was $1223 in the account, for 5 days there was $1223 + $615 in the account, for 7 days there was $1223 + $615 - $63 in the account, and for the last 9 days there was $1223 + $615 - $63 - $120 in the account.  This all happened over 30 days and to translate this to an equation it will look something like the following.

Convert to equation and simplify

Therefore, the final answer would be that the average daily balance of Elliott's account for the month of June would be $1583.9 per day.

The population proportion of red automobiles in the United States exists 22 %.

An analysis of two numbers in terms of their proportion. A ratio is said to be directly proportional to another if two sets of given numbers are increasing or decreasing in the same ratio.

The proportion of red automobiles in the United States(P) is given by:

P = [Number of red automobiles / Number of automobiles in US ]× 100

According to the table

Number of red automobiles = 32 + 29 + 23

Number of red automobiles = 84

Number of automobiles

= 32 + 29 + 23 + 18 + 36 + 25 + 4 + 17 + 11 + 25 + 26 + 39 + 10 + 46 + 33

Number of  automobiles = 374

put the values into the equation

P = [Number of red automobiles / Number of automobiles in US ] × 100

substitute the values in the above equation, we get

P = [84 Cars / 374 Cars] × 100

simplifying the above equation, we get

Proportional = 0.2245 × 100

Proportional = 22.45

Proportional = 22 percentage

Therefore, the correct answer is option D. 22 %.

Therefore the value of the z score comes out to be Z = 1.1261

Simply expressed, a z-score (sometimes called a standard score) gives you a sense of how distant from the mean a data point is. Technically, however, it's a calculation of how far a raw score deviates from or exceeds the population mean.

The range of Z-scores ranges from -3 standard deviations (which would be on the far left of the normal distribution curve) to +3 standard deviation. The mean and population standard deviation must be known in order to use a z-score.

Here,

In a World Atlas study, 10% of people have blue eye color. Lane decided to observe 44 people and she concluded 7 people had blue eyes. Calculating the z-score

Given that :

Sample size (n) = 44

Number of people with blue eyes (x) = 7

Proportion (p) = 10% = 0.1

Using the relation :

Z = (p" - p) / [tex]\sqrt{\frac{pq}{n} }[/tex]

Since : q = 1 - p = 1 - 0.1 = 0.9

p" = x / n = 7/ 44

p"= 0.15909

pq = 0.1 * 0.9 = 0.09

Hence,

Z = (0.15909- 0.1) / [tex]\sqrt{\frac{0.09}{44} }[/tex]

Z = 0.0509 / 0.0452

Z = 1.1261

Therefore the value of the z score comes out to be

A polynomial of degree N with the zeros {x₁, x₂, ...} and a leading coefficient a can be written as:

y = a*(x - x₁)*(x - x₂)*...*(x - xₙ)

Here we know that the degree is 3, and the zeros are {-1, -4, -1}

Then we can write the polynomial as:

y = a*(x + 1)*(x + 4)*(x + 1)

y = a*(x + 1)²*(x + 4)

We also know that the polynomial passes through (0, 8), replacing these values we will get:

Step-by-step explanation:

as percent means per 100

So we can say 0.54 or 54100 is the same as 54%.

hope understand

Answer:

B

Step-by-step explanation:

If we substitute a = 5 into the equation 3a = 15, we get b = 15.

Therefore, a = 5 and b = 15.

We are given that b is 3 times older than a, so b = 3a.

We are also told that in 5 years b will be 2 times older than a, so b = 2(a + 5).

We can set 3a = 2(a + 5) and solve for a.

3a = 2a + 10

2a = 10

a = 5

Therefore, a = 5 and b = 3a = 15.

We know that today, b is 3 times older than a. This means that b = 3a. We can use this equation to help us solve the problem.

We know that in 5 years' time, b will be 2 times older than a. This means that in 5 years, b = 2(a + 5). We can use this equation to help us solve for a and b.

We can set the two equations equal to each other, 3a = 2(a + 5). We can then solve for a, which gives us a = 5.

We can then substitute this value into either of the equations to find the value of b. If we substitute a = 5 into the equation 3a = 15, we get b = 15.

Therefore, a = 5 and b = 15.

Applying the AA similarity theorem, the length of DF is: 15 units.

When two angles in one triangle are congruent to the corresponding two angles in another triangle, both are said to be similar to one another. This means that, the corresponding sides of these two triangles would be proportional or have the same ratio.

In the image attached bellow, triangle DEF and triangle DBC are similar to each other because they have two pairs of corresponding angles that are congruent which are:

<DFE ≅ <DCB [right angles are equal]

<EDF ≅ <BDC [reflexive property of congruence]

Therefore, their corresponding sides will have equal ratios such as:

DC/DF = BC/EF
