11x + 6y = 6 then graph the equation

maw [93]

Answer:

Step-by-step explanation:

Use the intercept method of graphing a straight line:

Let x = 0. We get y = 1. This is the y-intercept (0, 1).

Let y = 0. We get x = 6/11. This is the x-intercept (6/11, 0).

Plot both points and then draw a straight line through them.

Solve -11 - x + = - 5 (2x-3) + 7

garri49 [273]

Answer:

Let's see what to do buddy...

Step-by-step explanation:

_________________________________

$- 11 - x = - 5(2x - 3) + 7$

$- 11 - x = - 10x + 15 + 7$

$- 11 - x = - 10x + 22$

Subtract the sides of the equation plus 11 :

$- x = - 10x + 22 + 11$

$- x = - 10x + 33$

Subtract the sides of the equation plus 10x

$10x - x = 10x - 10x + 33$

$9x = 33$

Divided the sides of the equation by 9 

$\frac{9}{9}x = \frac{33}{9} \\$

$x = \frac{33}{9} = \frac{3 \times 11}{3 \times 3} = \frac{11}{3} \\$

And we're done.

Thanks for watching buddy good luck.

Criterion: Identify IV, DV, and hypotheses and evaluate the null hypothesis for an independent samples t test. Data: Use the inf

Papessa [141]

The table is missing in the question. The table is provided here :

Group 1 Group 2

34.86 64.14 mean

21.99 20.46 standard deviation

7 7 n

Solution :

a). The IV or independent variable = Group 1

The DV or the dependent variable = Group 2

b).

$H_0: \mu_1 = \mu_2$

$H_a:\mu_1 < \mu_2$

Therefore, $t = \frac{\bar x_1 - \bar x_2}{\sqrt{\frac{s_1^2}{n_1}+\frac{S_2^2}{n_2}}}$

$t = \frac{34.86 - 64.14}{\sqrt{\frac{21.99^2}{7}+\frac{20.46^2}{7}}}$

t = -2.579143

Now, $df = min(n_1 - 1, n_2 - 1)$

df = 7 - 1

= 6

Therefore the value of p :

$=T.DIST(-2.579143,6,TRUE)$

= 0.020908803

The p value is 0.0209

$p< 0.05$

So we reject the null hypothesis and conclude that $\mu_1 < \mu_2$
