Area of a rectangle can be calculated by multiplying the length by the height.
So:

l x w
3 x 13
39 cm squared

Area of a triangle can be calculated by multiply the length by the height and dividing by two. So:

1/2 x l x w
1/2 x 10 x 8
40 m squared

Men women

Sample size 5 5

Mean rate 6.2 5.3

Mean diffference = $6.2-5.3=0.9$

Std error for difference = 0.25 (given)

Since we have two groups and also sample sizes are very small we can use t significant value for finding out confidence interval

df = 5+5-2 =8

t critical value for 80% two tailed = 1.397

Conf interval 80%

= $(0.9-1.397*0.25, 0.9+1.397*0.25)\\= (0.55525, 1.24475)$

The length of the side opposite B measures __ units

Sindrei [870]

For this case what we should do is observe the figure.

We note that the side opposite to vertex B is the AC side.

From here, we can see that the length of the AC segment is given by:

AC = 4

Therefore, the measurement on the side opposite to vertex B is equal to 4 units.

Answer:

The length of the side opposite B measures 4 units
