Answer:

y=2x+0

Step-by-step explanation:

y=mx+b, your slope (m) is 2 and your y intercept (b) is 0, so just plug it in

Slope Intercept Form: y = mx + b

Slope: 2

Y-Intercept: 0

Therefore, the slope intercept form of the given values would look like this:

y = 2x + 0 or just y = 2x

11th grade geometry:

Aliun [14]

Answer:

The perimeter is 72 units and the area is 149 square units.

Step-by-step explanation:

$\triangle SBA$ has coordinates $S(15,-8),B(-2,21)$ and $A(0,0)$

Using the distance formula.........

Length of side $SB = \sqrt{(15+2)^2+(-8-21)^2}= \sqrt{17^2+(-29)^2}= \sqrt{1130}$

Length of side $BA= \sqrt{(-2)^2+(21)^2}= \sqrt{445}$

Length of side $AS =\sqrt{(15)^2+(-8)^2}=\sqrt{289}=17$

So, the perimeter of the triangle will be: $(SB+BA+AS)= \sqrt{1130}+ \sqrt{445}+17 =71.71... \approx 72$ units. (Rounded to the nearest unit)

The height of the triangle for the corresponding base $SB$ is 8.89 units.

Formula for the Area of triangle, $A= \frac{1}{2}(base\times height)$

So, the area of the $\triangle SBA$ will be: $\frac{1}{2}(\sqrt{1130}\times 8.89)= 149.42... \approx 149$ square units. (Rounded to the nearest unit)

I need help please I’m confused

Ahat [919]

Answer:

The answer is 50 degrees

Step-by-step explanation:

The small box at the corner of the triangle indicates that the triangle is exactly 90 degrees, or a right angle. In order to solve the expression, you would need to do 40 + x = 90, which would be x = 50

The Carter Motor Company claims that its new sedan, the Libra, will average better than 31 miles per gallon in the city. Assumin

Nutka1998 [239]

Answer:

The null hypothesis $H_o : \mu = 31$

The alternative hypothesis $H_a : \mu > 31$

Step-by-step explanation:

From the question we are told that

The population mean is $\mu = 31 \ miles / gallon$

Generally

The null hypothesis is that the company's new sedan, the Libra, will have an average of $\mu = 31 \ miles / gallon$

This mathematically represented as

The null hypothesis $H_o : \mu = 31$

The alternative hypothesis is that the company's new sedan, the Libra, will have an average better than $\mu = 31 \ miles / gallon$

This mathematically represented as

The alternative hypothesis $H_a : \mu > 31$

When comparing more than two treatment means, why should you use an analysis of variance instead of using several t tests?

Finger [1]

Answer:

Because it increases the risk of Type 1 error

Step-by-step explanation:

ANOVA is the analysis of the variance .

When comparing more than two treatment means we use ANOVA because a t test increases the risk of type 1 error .

For example if we wish to compare 4 population means there will be 4C2 = 6 separate pairs and to test the null hypothesis that all four population means are equal would require six two sample t test. Similarly to test 10 population mean would require 45 separate two sample t test.

This has two disadvantages .

First the procedure is too lengthy and tediuos.

Second the overall level of significance greatly increases as the number of t- tests increases.

The analysis of the variance compares two different estimates of variance using the F distributionto determine whether the population means are equal.
