Gradient=Change in value of Y coordinates/Change in value of X coordinates.

Take two points on the line.( -2,2) and (-4,3)

Find Delta or change in the values

let assume X is the gradient.

X=3-2/-4-(-2)

X= 1/-4+2

X=1/-2 which is written as -1/2

Answer:

formula = y2-y1/x2-x1

Step-by-step explanation:

(-4,-2) (-3,5)

x1=-4       x2=-3

y1=-2        y2=5

5+2/-3+4=7

so M=7

y-y1=m(x-x1)

y+2=7(x+4)

2y=7x+28

rearrange

-7x+2y-28=0

Answer:

1844

Step-by-step explanation:

For polling firm survey on voters, the smallest sample size which is required to obtain the desired margin of error, is 1850.

The probability or the chances of error while choosing or calculating a sample in a survey is called the margin of error.

[tex]MOE=z\times\dfrac{\sigma}{\sqrt{n}}[/tex]

Here, z is the critical value and n is the sample size.

Here, a polling firm wants to use a one-sample z interval to estimate, the number of proportion of voters in a country plan on voting for a certain candidate.

The margin of error for this test is 3% or 0.03 and the confidence interval is 99 percent.

The z value on the confidence interval of 99 percent is 2.576. Here, the standard deviation for this survey is 50 percent, or 0.50.

Put the value in the above formula as,

[tex]0.03=(2.576)\times\dfrac{0.5}{\sqrt{n}}\\n\approx1850[/tex]

Hence, for polling firm survey on voters, the smallest sample size which is required to obtain the desired margin of error, is 1850.

Answer: 80%

Step-by-step explanation:

Goran watched 55 movies. Out of those movies, he thought 44 were very good.

The question needs to know what percentage this 44 very good movies comprised of the total number of movies.

= Number of very good movies / Total movies * 100%

= 44 / 55 * 100%

= 0.8 * 100%

= 80%

Step-by-step explanation:

Answer:

x = 120°

Step-by-step explanation:

We are given;

sec²x + 4secx = -4

Rearranging gives;

sec²x + 4secx + 4 = 0

Factorizing the left hand side gives;

(sec x + 2)(sec x + 2) = 0

This means that;

(sec x + 2) = 0

From trigonometry, we know that sec x = 1/cos x

Thus;

(1/cos x) + 2 = 0

1/cos x = -2

cos x = -1/2

cos x = -0.5

x = cos^(-1) -0.5

x = 120°

Step-by-step explanation:

a. Let the money in m savings account be represented by x.

If I doubled the money in my savings account, I would have $150.62. This means that:

(2 × x) = $150.62

2x = $150.62

Divide both side by x

2x/2 = $150.62/2

x = $75.31

The amount in the savings account is $75.31

b. Let the hourly wage be represented by x.

Three times the hourly wage plus $7.65 in tips equals $27.90. This will be:

(3 × x) + 7.65 = 27.90

3x + 7.65 = 27.90

3x = 27.90 - 7.65

3x = 20.25

x = 20.25/3

x = 6.75

The hourly wage is $6.75

Answer:

2

Step-by-step explanation:

2 is the only factor that goes into 6 and 16. (6th's Factors) 1, 2, 3 and 6

(16th Factors) 1, 2, 4, 8 and 16.

The greatest common factor of 6 and 16 is 2.

To find the greatest common factor (GCF) of 6 and 16, we need to determine the largest number that can divide both 6 and 16 without leaving a remainder.

First, we find the factors of each number:

Factors of 6: 1, 2, 3, 6

Factors of 16: 1, 2, 4, 8, 16

By comparing the factors, we can identify that both 6 and 16 have a common factor of 2. However, 6 also has a factor of 3, which is not a factor of 16.

To determine the GCF, we select the highest common factor, which is 2.

Therefore, the greatest common factor of 6 and 16 is 2.

The GCF is an essential concept in mathematics as it helps simplify fractions, factorize expressions, and solve various mathematical problems. It allows us to identify the largest number that can evenly divide two or more given numbers.

Answer: A. The probability of drawing a red tile is 36% and the probability of NOT drawing a red tile is 64%

Step-by-step explanation:

Number of red tiles = 9

Number of blue files = 10

Number of green tiles = 6

Total number of tiles = 9 + 10 + 6 = 25

Probability of drawing red tile = 9/25 = 0.36 = 36%

Probability of drawing blue tile= 10/25 = 0.40 = 40%

Probability of drawing green tile = 6/25 = 0.24 = 24%

Based on the explanation above, the correct answe is option A "The probability of drawing a red tile is 36% and the probability of NOT drawing a red tile is 64%".
