Answer:

[tex] y = 3x - 2 [/tex]

Step-by-step explanation:

The equation that describes how x

and y are related is given in the slope-intercept form, [tex] y = mx + b [/tex]

Where, m = slope, and b = y-intercept.

Let's find the value of m and b using the table of values given.

Using two of the pairs given, (-2, -8) and (-1, -5),

[tex] slope (m) = \frac{y_2 - y_1}{x_2 - x_1} = \frac{-5 -(-8)}{-1 -(-2)} = \frac{3}{1} = 3 [/tex]

Substitute x = -2, y = -8, and m = 3 in [tex] y = mx + b [/tex] to find the value of b.

Thus:

[tex] -8 = (3)(-2) + b [/tex]

[tex] -8 = -6 + b [/tex]

Add 6 to both sides

[tex] -8 + 6 = b [/tex]

[tex] -2 = b [/tex]

Substitute m = 3 and b = -2 in [tex] y = mx + b [/tex].

The equation that describes how x

and y are related would be:

[tex] y = 3x - 2 [/tex]

Consider the following hypothesis test:
H0: µ = 20
Ha: µ < 20
A sample of 50 provided a sample mean of 19.4. The population standard deviation is 2.
a. Compute the value of the test statistic (to 2 decimals).
b. What is the p-value (to 3 decimals)?
c. Using a = .05, can it be concluded that the population mean is less than 20?
d. Using a = .05, what is the critical value for the test statistic?
e. State the rejection rule: Reject H0 if z is the critical value.
f. Using a = .05, can it be concluded that the population mean is less than 20?

Answers

Answer:

[tex]z = - 2.12[/tex]

[tex]p- value = 0.017003[/tex]

There is sufficient evidence to show that the population mean is less than 20

[tex]z_{0.05} =- 1.645[/tex]

The decision rule is

Reject the null hypothesis

The conclusion is

There is sufficient evidence to show that the population mean is less than 20.

Step-by-step explanation:

From the question we are told that

The null hypothesis is [tex]H_o: \mu = 20[/tex]

The alternative hypothesis is Ha: µ < 20

The sample size is n = 50

The sample mean is [tex]\= x = 19.4[/tex]

The level of significance is [tex]\alpha = 0.05[/tex]

The population standard deviation is [tex]\sigma = 2[/tex]

Generally the test statistics is mathematically represented as

[tex]z = \frac{\= x - \mu }{ \frac{\sigma }{ \sqrt{n} } }[/tex]

=> [tex]z = \frac{19.4 - 20 }{ \frac{2}{ \sqrt{50 } } }[/tex]

=> [tex]z = - 2.12[/tex]

From the z table the area under the normal curve to the left corresponding to -2.12 is

[tex](P< -2.12) = 0.017003[/tex]

Generally the p-value is

[tex]p- value = 0.017003[/tex]

From values obtained we see that [tex]p-value < \alpha[/tex] hence

The decision rule is

Reject the null hypothesis

The conclusion is

There is sufficient evidence to show that the population mean is less than 20.

Generally form the normal distribution table the critical value at a level of significance of [tex]\alpha = 0.05[/tex] is

[tex]z_{0.05} =- 1.645[/tex]

Generally given that [tex]z < z_{0.05}[/tex]

The decision rule is

Reject the null hypothesis

The conclusion is

There is sufficient evidence to show that the population mean is less than 20.

What is the rate of change for the line that goes through the points (8,14) and (11, 19.25)

Answers

Answer:

1.75

Step-by-step explanation:

The rate of change for the line that goes through the points (8,14) and (11, 19.25) is known as the slope expressed as;

slope m = y2-y1/x2-x1

Substitute the coordinate pairs into the formula;

m = 19.25-14/11-8

m = 5.25/3

m = 1.75

Hence the rate of change for the line is 1.75.

a snail moves through a garden and travels 1 1/8 meters in 1 1/2 Minutes. What is the snails rate in Minutes per Meters

Answers

Answer:

Step-by-step explanation

Given

a snail moves through a garden and travels 1 1/8 meters in 1 1/2 Minutes.

Solution

the snails rate =11/8÷11/2

= 1/4Minutes per Meters

So the answer is 1/4 minute per meter

It is the quantity of an amount of something at a rate of one of another quantity.

If a snail moves through a garden and travels 1 1/8 meters in 1 1/2 Minutes.

The snail's rate in minutes per meter is 4/3 minutes.

What is a unit rate?

It is the quantity of an amount of something at a rate of one of another quantity.

Example:

3 miles in 60 minutes.

1 mile in 20 minutes.

We have,

Snail travels:

[tex]1\frac{1}{8}[/tex] meters = [tex]1\frac{1}{2}[/tex] minutes

9/8 meters = 3/2 minutes

Multiplying 8/9 on both sides.

1 meters = 8/9 x 3/2 minutes

1 meter = 4/3 minutes

This means that the snail's rate in minutes per meter is 4/3 minutes.

Thus,

If a snail moves through a garden and travels 1 1/8 meters in 1 1/2 Minutes.

The snail's rate in minutes per meter is 4/3 minutes.

Answers

Answer:

x = 30

Step-by-step explanation:

Since this is a right triangle,

90 = (x + 20) + (x + 10)

90 = x + x + 20 + 10

90 = 2x + 30

90 - 30 = 2x

60 = 2x

60/2 = 2x/2

30 = x

Check:

x + 20

30 + 20 = 50

x + 10

30 + 10 = 40

50 + 40 = 90
