Answer:

the slope of the line is -2

Step-by-step explanation:

since the line is going downhill the slope is always negative. The top point is 2 lines above the bottom one and 1 over the slope is -2/1 but simplified is just negative 2

Answer:

Step-by-step explanation:

if you use the rise over run equation the slope would be 3/1

The equivalent ratios are 6:3, 24:12 and 18:9.

According to the question,

We have the following information:

We have a table where number of people and  benches are given.

(Note that equivalent ratios mean that when we simplify it then the ratio should be equal to the original ratio.)

Now, we will find the equivalent ratios column-wise:

In first column, we have 6 and 3.

6:3

Now, in second column, we have:

_:12

Now, dividing 12 by 3, we have 4.

Multiplying 4 into 6:

24:12

Now, in third column, we have:

18:_

Dividing 18 by 6:

18/6 = 3

Multiplying 3 by 3:

18:9

Hence, the equivalent ratios are 6:3, 24:12 and 18:9.

gof(x) is x/2+3/4 for functions f(x)=2x+3 and g(x)=x/4

A relation is a function if it has only one y-value for each x-value.

Composite functions are when the output of one function is used as the input of another.

Given,

f(x)=2x+3 and g(x)=x/4

g circle f of x equal to g of f of x.

and gof(x)=g(f(x))

g circle f of x equal to g of two times of x plus three.

gof(x)=g(2x+3)

gof(x)=(2x+3)/4

=2x/4+3/4

gof(x)=x/2+3/4

Hence gof(x) is x/2+3/4 for functions f(x)=2x+3 and g(x)=x/4

The equation of the line y = -x/2 + 6, with slope -1/2,

What is equation straight line?

Y = mx + c is the general equation for a straight line, where m denotes the line's slope and c the y-intercept. It is the version of the equation for a straight line that is used most frequently in geometry. There are numerous ways to express the equation of a straight line, including point-slope form, slope-intercept form, general form, standard form, etc. A straight line is a geometric object with two dimensions and infinite lengths at both ends. The formulas for the equation of a straight line that are most frequently employed are y = mx + c and axe + by = c. Other versions include point-slope, slope-intercept, standard, general, and others.

slope m = -1/2.

So the line can be formed by (y-y1) = m (x-x1)

(y-7) =  -1/2* (x+2)

y = -x/2 - 1+7

y = -x/2 + 6

Hence the equation of the line y = -x/2 + 6.

Answer:

The correct answer is B. Vertical lines have an undefined slope.

30% of the area under the normal curve lies to the left of -0.52 z - score.

What is z - score?

The relationship between a value and the mean of a group of values is quantified by a Z-score. The Z-score is calculated using standard deviations from the mean. When a data point's Z-score is 0, it means that it has the same score as the mean.

To find the z - score, divide your data point by your standard deviation after taking your data point and subtracting the mean from it.

Here, 30% = 0.30

So,

P(Z < z) = 0.30

From z - table, z - score for the probability 0.30 is -0.5244

-0.5244 ≈ -0.52

Hence, 30% of the area under the normal curve lies to the left of -0.52

Val's margin of error is of 10 pounds rounded to the nearest whole number.

In statistics, a confidence interval is a range to estimate for unknown terms. The most common level is the 95% confidence interval.

It can be calculated by

CI = Mean ± margin of error.

Margin of error can be calculated by the following equation:

M = 1.96 s /√n

where s is the standard deviation. n is the sample size.

In this problem:

The standard deviation is 50, hence s = 50

Val weighed 100 cows. n = 100

Then:

M = 1.96 s /√n

M = 1.96 x 50 /√100

M = 1.96 x 50 /10

M = 9.8

Step-by-step explanation:

b² - 4ac = (-6)² - 4(1)(4) = 36 - 16 = 20

The equations that have a true solution include the following:

8⋅72−12=22−2⋅3 fraction numerator 8 times 7 over denominator 2 end fraction minus 12 equals 22 minus 2 times 3.

48 ÷ 8 + 2³ = 5 + 3²

In this exercise, we have to determine the equations that are true and this would  be done by simplifying and evaluating each of the equations as follows:

(8 × 7)/2 - 12 = 22 - (2 × 3)

Opening the bracket on both sides of the equation, we have:

56/2 - 12 = 22 - 6

28 - 12 = 16

16 = 16 (True).

48 ÷ 8 + 2³ = 5 + 3²

Next, we would evaluate the exponents as follows:

48 ÷ 8 + 8 = 5 + 9

6 + 8 = 14

14 = 14 (True).

150/5² = 30 - 4² - 12

By evaluating the exponents, we have the following:

150/25 = 30 - 16 - 12

6 = 2 (False).

9² - 7² = 20 ÷ (7 - 2)

Opening the bracket, we have the following:

9² - 7² = 20 ÷ 5

By evaluating the exponents, we have the following:
