The graph of Y > -2x + 4 can be drawn by plotting points on a coordinate plane and connecting them with a dashed line. The dashed line should be above the line Y=-2x+4.

A sample graph is shown below:

[Graph of Y > -2x + 4]

(0,4), (1,1), (2,-2), (3,-5), (4,-8)

To graph Y > -2x + 4, you need to plot points on a coordinate plane. Start by finding the intersection point of the line Y=-2x+4 and the x-axis, which will be (0,4). From there, you can calculate the coordinates of the other points by substituting x values into the equation and solving for y. For example, when x=1, y=-2x+4=-2+4=2, so the point (1,2) would be plotted. Then, plot the other points (2,-2), (3,-5), and (4,-8). Finally, connect the points with a dashed line to represent Y > -2x+4.

The solid formed by rotating the above rectangle around the horizontal axis shown is best described as a cylinder with radius 3cm and height 6cm. The volume of this solid is 108 cubic centimeters, which can be calculated as follows: V = πr2h, where r is the radius and h is the height. In this case, r = 3cm and h = 6cm, so the volume is π x (3 cm)2 x 6 cm = 108 cubic centimeters.

Answer:

x = 1.636364

x = 1.64 (simplified)

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

0.7x=1.8−0.4x

0.7x=1.8+−0.4x

0.7x=−0.4x+1.8

Step 2: Add 0.4x to both sides.

0.7x+0.4x=−0.4x+1.8+0.4x

1.1x=1.8

Step 3: Divide both sides by 1.1.

1.1x/1.1=1.8/1.1

x=1.636364

x = 1.64 (simplified)

Answer:

x = 1.636364

Explanation:

0.7x = 1.8 − 0.4x

0.7x = 1.8 − 0.4x

0.7x = 1.8 + −0.4x

0.7x = −0.4x + 1.8

0.7x + 0.4x = −0.4x + 1.8 + 0.4x

1.1x = 1.8

Divide both sides by 1.1

1.1x / 1.1 = 1.8 / 1.1

When the area corresponding to the critical value is in the lower tail of the sampling distribution, the p-value is the area under the curve less than or equal to the critical value. Therefore, the correct answer is a. less than or equal to the critical value.

The critical value is the point on the sampling distribution that separates the rejection region from the non-rejection region. If the test statistic falls in the rejection region, we reject the null hypothesis. The p-value is the probability of obtaining a test statistic as extreme or more extreme than the one observed, given that the null hypothesis is true. If the p-value is less than or equal to the critical value, we reject the null hypothesis.

In the case of a lower-tailed test, the critical value is in the lower tail of the sampling distribution, and the p-value is the area under the curve to the left of the test statistic. If the p-value is less than or equal to the critical value, it means that the test statistic falls in the rejection region and we reject the null hypothesis.

To find the average quarterly loads for the rest of the years, you can use the formula below:

Average Quarterly Load = Total Annual Load  4 For example, let's say the total annual load for Year 1 is 800.

To find the average quarterly loads for Year 1, we would divide 800 by 4 to get an average quarterly load of 200. Then, you can use this average quarterly load to find the seasonal indices for each quarter of each year.To find the seasonal index for a given quarter and year, you would divide the actual quarterly load by the average quarterly load for that year.

For example, let's say the actual load for Quarter 1, Year 1 is 240. To find the seasonal index for this quarter and year, we would divide 240 by 200 to get a seasonal index of 1.2. You would repeat this process for each quarter and year to find the seasonal indices for all quarters and years.

Answer:

3:8

Step-by-step explanation:

The ratio of Mina's age to Naomi's age is 3 : 4

Multiplying the above ratio by 2 = 6:8

The ratio of Lev's age to Mina's age is 1 : 2

Multiplying the above ratio by 3

= 3:6

Therefore, ratio of Lev's age to Naomi's age in simplest form.

= 3:8

Answer:

3:8

Step-by-step explanation:

Let L, M, and N stand for the three ages.

The given ratios tell us that

M = 2L

and

N = 4/3M.

Therefore,

N = 4/3 x 2L = 8/3L.

This means that Lev's and Naomi's ages are in the ratio 3:8.

The range of the test scores in Mr. Miller's math class is 42.

Mathematically, the range refers to the difference between the highest value and the lowest value in a data set.

The range is computed by subtraction of the lowest value from the highest value.

Mr. Miller can use the range to measure the spread or dispersion of the test scores.

Test Scores:

52, 61, 69, 76, 82, 84, 85, 90, 94

Highest score = 94

Lowest score = 52

Range = 42 (94 - 52)

Thus, we can conclude that for the math students in Mr. Miller's class, the range of their test scores is 42.

The approximate probability that the observed responses would be as far or farther from the expected responses if there is no association between age-group and preference is approximately 0.1282.

To determine the probability that the observed responses would be as far or farther from the expected responses if there is no association between age-group and preference, we need to calculate the p-value associated with the test statistic.

Since the p-value is not provided directly, we cannot determine the exact probability. However, we can make an estimation based on the given options.

The p-value represents the probability of obtaining a test statistic as extreme or more extreme than the observed value, assuming no association between the variables. A smaller p-value indicates stronger evidence against the null hypothesis of no association.

Among the given options, the smallest value is 0.0001. If this were the correct option, it would suggest a very small probability of the observed responses occurring by chance alone if there were no association.

To make an estimation, we typically compare the p-value to a significance level (usually 0.05) to determine statistical significance. If the p-value is smaller than the significance level, we reject the null hypothesis in favor of the alternative hypothesis.

Based on the options provided, the closest value to the conventional significance level of 0.05 is 0.1282. This suggests that if the p-value associated with the test statistic of 4.108 is approximately 0.1282 or larger, the observed responses would not be considered statistically significant, and we would fail to reject the null hypothesis of no association between age-group and preference.

The given linear function is \(f (h) = - \frac{1}{5} x + 3\). The graph is attached at the end.

Let the independent variable be x.

It is given in the question:

Value of the function, h at 0 = 3

Thus, h(0) =3

Also, when the independent variable decreases by 5, the dependent variable increases by 1.

So, slope = -\(\frac{1}{5}\)

y-intercept = 3

We know the linear equation is-

y = mx + b ... (i)

where y ⇒ linear function

m ⇒ slope of the line

x ⇒ independent variable

b ⇒ y-intercept

Putting the values of each term in equation (i), we get:

\(h (x) = - \frac{1}{5} x + 3\)

Matt drinks water 12 times on his bike ride and eat snack 4 times.

Let us assume that Matt drinks water m times and eat snack n times.

Here, Matt bikes 25 miles, take a short break, and then bikes another 11 mile.

This means that onnhis bike ride he traveled total 25 + 11 = 36 miles.

Matt drinks water every 3 mile.

So, by unitary method,

m = total distance / 3

m = 36/3

m = 12

This means that he drinks water 12 times.

And he eat a snack every 9 mile.

So, by unitary method the value of n would be,

n = total distance / 9

n = 36 miles / 9 miles

n = 4

Answer:

x = 0, y = 1

Step-by-step explanation:

2x + 6y = 6 → (1)

x - 3y = - 3 ( add 3y to both sides )

x = 3y - 3 → (2)

substitute x = 3y - 3 into (1)

2(3y - 3) + 6y = 6 ← distribute parenthesis and simplify left side

6y - 6 + 6y = 6

12y - 6 = 6 ( add 6 to both sides )

12y = 12 ( divide both sides by 12 )

y = 1

substitute y = 1 into (2)

x = 3(1) - 3 = 3 - 3 = 0

solution is x = 0 , y = 1
