Answer:

To find the sum of interior angles in a polygon, we can use the formula:

180(n-2) where n is the number of sides.

Since this is pentagon (5 sides), then 180(5-2)=180*3=540

The missing angle would then be

540-97-111-104-115=113

Since angles on a straight line add up to 180, then

x+113=180

x=67

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 $\mu_1 < \mu_2$

Eight friends are going bowling together if they each rent a pair of bowling shoes for $2.00, they each play two
Mnenie [13.5K]

2.00+1.50= 3.50.

3.50x8= 28.00

I'm assuming they each paid 41.00 dollars for two games,

41.00x8= 328.00

328.00+28.00= $356.00

Hope this is correct and/or it helps!

Sorry, didn't realize my mistake.
