If 1/2 gallon covers 1/12 of a wall, then there are 12 quarts of paint that are needed to cover the entire wall.

One gallon is equal to 4 quarts.

The amount of gallon that covers 1/12 of a wall = 1/2.

1/2 gallon = 2 quarts

This means that 2 quarts are needed to cover 1/12 of a wall.

Now, the number of quarts needed to cover the entire wall = 1/12 × 2= 1.

Therefore, if 1/2 gallon covers 1/12 of a wall, then there are 12 quarts of paint that are needed to cover the entire wall.

The equation in slope-intercept form that represents the situation is y = 7x - 598

The slope of a line is the ratio of the amount that y increases as x increases some amount. Slope tells you how steep a line is, or how much y increases as x increases. The slope is constant (the same) anywhere on the line.

The ordered pair are ( 98, 88) and (107, 151)

Equation of line in slope-intercept form is y = mx + c

at x = 98, y =88

so that by substituting we have,

88 = 98m + c -------------------1

at x = 107, y = 151 and by substituting we have

151 = 107m + c -----------------2

subtract equation 1 from 2

63 = 9m

m = 63/9

m = 7

substitute m = 7 in equation 1

88 = 98(7) + c

c = 88 - 686c

c = -598

Overall, available research suggests jurors exposed to pretrial publicity are more likely to favor the prosecution.

The statement which describes the relationship between the graph of f (x) and the graph of g(x) = f (x) - 4 is the graph of​​ f(x)​ translated 4 units down.

The standard form of transformation can be described as,

g(x) = f(x + a) + b  .... (1)

If a > 0, then the graph of f(x) shifts left side by a unit and if If a < 0, then the graph of f(x) shifts right side by a units.

If b > 0, then the graph of f(x) shifts upward by b unit and if If a < 0, then the graph of f(x) shifts downward by b units.

Since the relationship between the graph of f(x) and g(x) exists,

g(x) = f(x − 4)

From (1), we get

The value of a exists -4, therefore the graph of f(x) translated 4 units down.

The value of a function exists defined on a graph by the vertical distance from the x-axis. When that vertical distance exists reduced by 4, the corresponding point exists shifted down 4 units.

Therefore, the correct answer is option A) The graph of g(x) is the graph of​​ ​f(x)​ translated 4 units down.

The Pythagorean Theorem of an equilateral triangle is a²+b²=c²

The height of an equilateral triangle is defined as a line drawn from any vertex on the opposite side of the triangle. This is the opposite side's perpendicular bisector. This means it cuts the opposite side in half and produces a 90° angle with it. The altitude that separates an equilateral triangle into two congruent right-angled triangles is also known as the triangle's height.

To calculate the missing side lengths of an equilateral triangle, use the Pythagorean theorem and the height of the right triangles within the equilateral.

The area of an equilateral triangle can therefore be determined using the formula A = 3/4 (a2).

The Pythagorean Theorem of an equilateral triangle is,

a(√3/2a)+b(√3/2b)=c(√3/2c)

√3/2a²+√3/2b²= √3/2c²

√3/2(a²-b²)= √3/2(c²)

a²+b²=c²

The classification of the equations as direct or indirect variations are;

1) Direct Variation

2) Direct Variation

3) Indirect Variation

4) Indirect Variation

Direct variation occurs when one quantity changes and the other quantity changes as well in direct proportion. Meanwhile, Inverse variation is exactly opposite of that.

Now, let us answer the questions;

1) y = 4x + 1

This shows that y is directly proportional to x because as x is increasing, y is increasing and vice versa. Thus, it is a direct variation.

2) y = 7.5x

This shows that y is directly proportional to x because as x is increasing, y is increasing and vice versa. Thus, it is a direct variation.

3) y = (1/15)x

This shows that y is inversely proportional to x because as x is increasing, y is decreasing and vice versa. Thus, it is an indirect variation.

4) y = 6/x

This shows that y is inversely proportional to x because as x is increasing, y is decreasing and vice versa. Thus, it is an indirect variation.

Step-by-step explanation:

The radius is equal to half of the diameter. The diameter in this problem is 8 units; half of 8 is 4.

Answer:

The radius would be 4.

Step-by-step explanation:

The radius is always half of the diameter, which would be all the way around the circle. The radius would be halfway around the circle.

So looking at the graph, we can see that the circle surrounds the origin (0) 4 spots to the left and 4 spots to the right. This represents the diameter which is 8 and this can be found by adding the two directions (4 + 4) which gets you 8 as a sum. Now knowing this, we simply divide 8 by 2 and we get the radius which is 4.

Therefore, the answer is 4.

What is standard deviation?

Your dataset's average level of variability is represented by the standard deviation. It reveals the average deviation of each statistic from the mean.

                               A low standard deviation means that values are clustered close to the mean, whereas a high standard deviation means that values are typically far from the mean.

P(X> 30 )

Normal distribution

μ = 25.5

σ = 4.5

P(X > 30 ) = Area to the right of 30

we convert this to standard normal using z = x - μ/σ

 z = 30 - ( 25.5 )/45  = 1.00

P(Z > 1.00 ) = Area to the right of 1.00

P( X > 30) = P( Z > 100) = 1 - P( Z < 1.00 ) = 1 - 0.8413
